Parrots That Show Selfless Kindness

A good study has recently been done on grey parrots.

According to Charles Darwin, helping others just doesn’t make sense. Yet we’ve seemingly seen altruism time and again in the animal kingdom: in primates, in canines, in cetaceanspinnipeds, even vampire bats. Now, for the first time, it’s been demonstrated in birds.

The kind bird is one of the titans of avian intelligence, the African grey parrot (Psittacus erithacus). New experiments have shown these birds happily helping each other acquire treats, without any assumption or anticipation that their altruism will be reciprocated.

“We found that African grey parrots voluntarily and spontaneously help familiar parrots to achieve a goal, without obvious immediate benefit to themselves,” explained behavioural biologist Désirée Brucks of the Max Planck Institute for Ornithology.

But the birds take it one step further. Unlike primates, for example, the parrots display no anger or envy if one of their friends receives favourable treatment, instead seeming quite content that good things are happening to a buddy.

Among the bird kingdom, it’s the corvids – such as crows and ravens – that are probably the most famed for their wicked smarts, and with very good reason. In fact, corvids have demonstrated skills previously only observed in primates.

However, the researchers said, corvids have failed tests of altruism. But there are other smart birds out there – like parrots. Cockatoos can make their own tools, and have even demonstrated playful creativity. And African grey parrots have proven to be smarter than a human child in some tests.

So, the research team designed a test for altruism, and gave it to two different types of parrots – eight African greys, and six blue-headed macaws (Primolius couloni).

The birds had been previously trained to exchange tokens (metal washers) for treats. This training was refreshed, and the scientists assessed their subjects’ relationships with other birds of their species. Each bird was tested with one bird with whom they had a close bond, and a second bird with a less close bond.

The birds were then placed in a clear perspex enclosure, with a dividing wall between them. The front of the box had holes through which items could be exchanged with a human; and the dividing wall between the birds also had a hole, through which the two birds could also exchange items.

All the birds quickly understood the concept of swapping the washer for a piece of walnut, and were able to do so. But, when only one of two birds was given tokens, only the African grey parrots, not the macaws, also deliberately gave tokens to their buddies.

“Remarkably, African grey parrots were intrinsically motivated to help others, even if the other individual was not their friend, so they behaved very ‘prosocially,'” said zoologist Auguste von Bayern of Oxford University.

“It surprised us that 7 out of 8 African grey parrots provided their partner with tokens spontaneously – in their very first trial – thus without having experienced the social setting of this task before and without knowing that they would be tested in the other role later on. Therefore, the parrots provided help without gaining any immediate benefits and seemingly without expecting reciprocation in return.”

In all, they voluntarily gave other African grey parrots 157 out of 320 tokens – nearly half. And, interestingly, although they passed tokens regardless of their social bond, they did give more tokens to birds with whom they shared a close bond.

The macaws, by contrast, rarely passed their tokens through to the other parrot. If they did, they dropped it through the hole; and they did it more often when the human experimenter was present. This led the scientists to believe the macaws were trying to pass the token to the human, not their buddy.

The difference could be due to social differences between the species in the wild, but there was one more interesting thing. In a separate recent study, the researchers showed that, when an African grey parrot sees a friend getting a better treat, they didn’t seem particularly bothered. This is in contrast to animals such as chimpanzees, who tend to get riled up about it.

According to von Bayern, this could be because the parrots monogamously mate for life.

“Given that parrots are so closely bonded with a single individual and thus so mutually interdependent, it does not make any difference if one of them gets a better pay-off once in a while,” she said.

“What counts is that together, they function as a unit that can achieve much more than each of them on their own (in addition to raising their joint offspring). This is probably why parrots are much more tolerant towards unequal treatment than species that are not long-term monogamous, while still being excellent cooperators.”

The research has been published in Current Biology.

Extreme Weather Will Continue to Worsen as the Climate Crisis Becomes More Severe

The changing climate is already having dire consequences on global societies, and the effects will become much worse in the future unless political leaders suitably address the environmental crisis of rising temperatures.

The past decade has been the hottest on record, the UN said Wednesday, warning that the higher temperatures were expected to fuel numerous extreme weather events in 2020 and beyond.​

The World Meteorological Organization, which based its findings on analysis of leading international datasets, said increases in global temperatures had already had dire consequences, pointing to “retreating ice, record sea levels, increasing ocean heat and acidification, and extreme weather”.

WMO said its research also confirmed data released by the European Union’s climate monitor last week showing that 2019 was the second hottest year on record, after 2016.

“The year 2020 has started out where 2019 left off – with high-impact weather and climate-related events,” WMO chief Petteri Taalas said in a statement, pointing in particular to the devastating bushfires that have been raging in Australia for months.

The bushfires, unprecedented in their duration and intensity, have claimed 28 lives and highlighted the type of disasters that scientists say the world will increasingly face due to global warming.

The fires have already destroyed more than 2,000 homes and burnt 10 million hectares (100,000 square kilometres) of land – an area larger than South Korea or Portugal.

“Unfortunately, we expect to see much extreme weather throughout 2020 and the coming decades, fuelled by record levels of heat-trapping greenhouse gases in the atmosphere,” Taalas said.

The UN agency said that average global temperatures during both the past five-year (2015-2019) and 10-year (2010-2019) periods were the highest ever recorded.

“Since the 1980s each decade has been warmer than the previous one,” the UN agency said in a statement, warning that “this trend is expected to continue”.

The United Nations said last year that human-made greenhouse gas emissions needed to tumble 7.6 percent each year to 2030 in order to limit temperature rises to 1.5 Celsius – the more ambitious cap nations signed up to in the landmark Paris climate deal.

Current pledges to cut emissions put Earth on a path of several degrees warming by the end of the century.

Not a fluke

Taalas said that since modern records began in 1850, the average global temperature had risen by around 1.1 degrees Celsius, and warned of significant warming in the future.

“On the current path of carbon dioxide emissions, we are heading towards a temperature increase of 3 to 5 degrees Celsius by the end of the century,” he warned.

Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, which provided one of the datasets, added that the trend line was unmistakable and could not be attributed to normal climate variability – a position taken by US President Donald Trump.

“What’s happening is persistent, not a fluke due to some weather phenomenon: we know that the long-term trends are being driven by the increasing levels of greenhouse gases in the atmosphere,” he said.

Data from the US National Oceanic and Atmospheric Administration meanwhile revealed that polar sea ice coverage continued its downward trend in 2019.

Both the Arctic and Antarctic oceans recorded their second-smallest average annual sea-ice coverage during the 1979–2019 period of record, the agency said.

Broken record

WMO also highlighted a new study published this week in Advances in Atmospheric Sciences with data showing that ocean heat content was at a record high in 2019.

The past five years were also the warmest on record in terms of ocean heat content, that study showed.

Since more than 90 percent of excess heat is stored in the world’s oceans, their heat content is a good way to quantify the rate of global warming, WMO said.

Conservationists said the UN agency’s findings were to be expected.

“It is no surprise that 2019 was the second hottest year on record – nature has been persistently reminding us that we have to pick up the pace,” said Manuel Pulgar-Vidal, leader of WWF’s global climate and energy practice, calling for dramatic measures to halt the warming trend.

“This is not so much a record as a broken record,” added Chris Rapley, a professor of climate science at University College London.

“The message repeats with grim regularity. Yet the pace and scale of action to address climate change remains muted and far from the need.”

Reducing the Very Overpriced Cost of Healthcare

As is known to many people, American healthcare is far more expensive than necessary.

One of most enduring, economically and socially damaging, downright frustrating facts about life in the United States is how expensive health care is here. Not only does U.S. health care cost far more than in other advanced economies, but compared with the nations that spend less, we have worse or equivalent health outcomes. In fact, U.S. life expectancy now lags behind that of all the advanced economies.

An MRI scan that cost $1,400 here went for $450 in Britain and $190 in Holland. Thirty tablets of a drug to reduce the risk of blood clots (Xarelto) cost $380 here, $70 in Britain, $80 in Switzerland and $60 in Holland. Hospital admission for angioplasty is $32,000 here, $15,000 in Australia, $12,000 in Britain, $7,000 in Switzerland, $6,000 in the Netherlands.

Add to those differences the latest outrage in health-care costs: surprise medical billing, when even well-insured patients can wake up from surgery finding that they owe thousands of dollars, because someone treating them while they were unconscious was out of their insurance network.

Princeton economists Anne Case and Angus Deaton (a Nobel winner) recently summarized the problem by labeling it an $8,000-a-year annual health-care tax paid by U.S. families. This is the difference in costs between what we pay for health care and what people in other countries pay. As Case put it: “We can brag we have the most expensive health care. We can also now brag that it delivers the worst health of any rich country.”

Why call this expense a tax? Well, for one, if you want health coverage, you can’t escape it. But even if you don’t — and good luck with that — you still can’t escape the tax, as both employer- and government-provided health care extract payments through lower paychecks and public financing.

Case and Deaton may be erring on the low side in their $8,000-per-family figure. The Organization for Economic Cooperation and Development puts per-person spending in the United States at $8,950 a year. That compares with $5,060 in Germany, $3,470 in Canada and just $3,140 in Britain. If we assume a family of three, we would get an annual health-care tax of $11,670 compared with Germany and more than $17,000 compared with the cost of health care in Britain.

How can such differences persist, especially in a service where consumption is so essential to well-being? If ice cream were that much more expensive here, we’d have a lot to squawk about, for sure. But it wouldn’t be a matter of life and death.

An obvious, and correct, answer as to why U.S. health care is so expensive is because we do so little, relative to other systems, to control costs. But it’s worse than that. We do a fair amount to make health care more expensive.

First, our system of private insurance costs far more than single-payer systems like Canada’s, and also more than countries with private but heavily regulated insurers like Germany. OECD data show that as a share of health spending, our administrative costs are three times that of Canada’s and twice that of Germany’s. Getting our administrative costs closer to those in other countries would require regulating private insurers and expanding public coverage, but it could save us at least 10 percent of our total health-care bill.

Next, we pay twice as much to our health-care providers and for prescription drugs as everyone else. The latter costs us more than $3,000 per family per year. We pay more than twice as much for medical equipment, costing us a bit less than $1,500 per family per year. Doctors and dentists cost us close to an extra $750 per family per year.

One reason for the outsize costs of these inputs to U.S. health care is that government policy protects our providers. When it comes to manufactured goods, like cars and clothes and almost everything on the shelves of Walmart, economists and policymakers push for “free trade” and more competition. But when it comes to health-care providers, these same authorities turn protectionist.

In areas like prescription drugs and medical equipment, this protection is explicit: Manufacturers are granted patent monopolies. The government will arrest anyone who sells protected items in competition with a patent holder.

In the case of doctors, we have maintained or increased barriers that make it difficult for qualified foreign physicians to practice in the United States. We also prevent other health-care professionals, such as physicians’ assistants and nurse practitioners, from doing many tasks for which they are entirely competent. There is a similar story with dentists and dental hygienists.

Other countries directly control drug prices. In France, the government determines whether a new drug is an improvement or a copycat, and, if the drug is deemed useful, the government negotiates drug prices with the manufacturers and caps their revenue. When sales exceed the cap, the manufacturer must rebate most of the difference back to the government.

Here in the United States, we give drug companies and medical equipment manufacturers’ patent monopolies and allow them to charge whatever they want. We don’t even let the government use its massive leverage to negotiate lower drug prices for Medicare beneficiaries. That’s what makes these goods expensive; they’re almost always relatively cheap to produce.

This is fixable. It would take regulating costs, reducing reimbursements to providers and increasing competition.

The pharmaceutical industry’s rationale for cost-exploding medical patents is that it helps incentivize research and innovation. Without them, it’s likely that pharmaceuticals and medical equipment companies would do less speculative research. But it would take a fraction of the savings from reducing such protectionism to replace patent-support research with publicly supported research (for which we already spend $40 billion a year).

In terms of boosting competition, allowing foreign doctors whose training meets our standards to more easily practice medicine here would bring U.S. physicians’ pay in line with international standards. Of course, our doctors pay much more for their education than doctors trained elsewhere, so part of this new structure would also require reducing the domestic cost of medical education and alleviating some of the educational debt burden that U.S.-trained doctors have acquired.

Increasing competition would also require using antitrust measures to push back on the pricing power engendered by the consolidation of both hospital groups and medical practices. An analysis by the New York Times of 25 metro areas found that hospital mergers “have essentially banished competition and raised prices for hospital admissions.”

Even if we succeed in raising competition and reducing protectionism, health care will still be too expensive for many low- and moderate-income families, many of whom have suffered stagnant incomes in recent decades. Like every other wealthy country, we will need to get on a path to universal coverage. But whatever form that takes, if we can significantly reduce our current health-care tax, the savings will easily be large enough to extend quality, affordable coverage to every American.

How Toxic Chemicals Are Robbing Vulnerable Children of Millions of IQ Points

The crisis of contaminated water seen in Flint, Michigan is ongoing and terrible, but other related events of contamination are more common than people tend to think they are. America is a society with many protections for the most powerful, and not enough for the most vulnerable.

The chemicals we’ve long feared the most – heavy metals like lead and mercury – are less of a threat to kids’ developing brains than they were two decades ago. But two new menaces may be taking their place: pesticides and flame retardants.

According to new research from New York University, flame retardants resulted in a loss of 162 million IQ points among children in the US between 2001 and 2016.

The study, published Tuesday in the journal Molecular and Cellular Endocrinology, looked at the four chemicals known to impact the brain of a developing child most: lead, mercury, pesticides, and polybrominated diphenyl ethers (otherwise known as flame retardants).

Leo Trasande, a paediatrician and public-health researcher at NYU who co-authored the study, described these pollutants as “hit-and-run” chemicals: Once a child is exposed to them, there’s no reversing the damage.

“Kids’ brain development is exquisitely vulnerable,” Trasande told Business Insider. “If you disrupt, even with subtle effects, the way a child’s brain is wired, you can have permanent and lifelong consequences.”

The study found that lead cost US kids 78 million IQ points during the 15-year period studied, while pesticides caused a loss of nearly 27 million IQ points during those years. Mercury, meanwhile, caused a loss of 2.5 million IQ points.

Children’s’ lower IQs are costing the US trillions of dollars

The researchers found that among kids exposed to toxins from 2001 to to 2016, the proportion of IQ loss due to exposure to flame retardants and pesticides increased from 67 percent to 81 percent. Flame retardants can be found in household furniture and electronics, while pesticides can be consumed when they linger on produce.

“What we found was quite striking,” Trasande said.

“We know that there is no safe level of lead exposure. The same is true for methylmercury, pesticides, and flame retardants.”

The study also found that there is an economic cost to childhood brain damage: Trasande said that each individual IQ point is worth roughly 2 percent of a child’s lifetime economic productivity. So if a child could potentially make US$1 million over the course of their lifetime, they would lose US$20,000 for every IQ point lost.

“A kid’s brain power is the engine of our economy,” Trasande said.

“If a child comes back from school with one less IQ point, maybe mum or the parent might not notice. But if 100,000 children come back with one less IQ point, the entire economy notices.”

According to the researchers, IQ loss due to lead, mercury, flame retardants, and pesticide exposure combined cost the US around US$6 trillion from 2001 to 2016.

Regulations on flame retardants and pesticides are more lax than heavy metals

For decades, scientists have understood that exposure to lead and mercury can result in childhood brain damage. So many of the main hideouts for these chemicals – leaded gasoline, lead paint, and mercury emissions from coal-fired power plants – have been phased out.

As early as the 1970s, the Environmental Protection Agency required lead to be phased out of gasoline and paint (though lead paint can still be found in homes built before 1978).

The agency also set standards to reduce mercury emissions from coal-fired power plants in 2011, though some power plants still do not meet these requirements.

But there have been fewer efforts to regulate pesticides and flame retardants.

The EPA has banned around 37 pesticides, though more than 500 have been used in the US. Another 97 have been voluntarily withdrawn by pesticide manufacturers.

More than a dozen states have adopted legislation that restricts the use of flame retardants in products like furniture, carpeting, and children’s toys, but none of the chemicals are banned federally.

Ways to reduce kids’ exposure

Many factors can influence a kid’s exposure to a chemical, Transande said.

“The science has really evolved such that the dose is not the only thing that makes the poison,” he said. Other factors to consider could include the timing and frequency of exposure.

Trasande added that regulating all of these chemicals has a far lower long-term economic cost than the cost of kids’ lost IQ points due to exposure.

To minimise personal risk in one’s own home, Trasande suggested simple steps like opening windows so that dust laced with flame retardants can escape. He also suggested vacuuming frequently and using a wet mop to sop up chemicals on the floor.

In addition, parents should avoid mattresses and children’s toys that contain polyurethane foam (which often carries flame retardants).

Trasande also said households should avoid spraying pesticides on their lawns or backyards and recommended switching to organic foods (though organic produce can also contain pesticides).

“We’ve made less progress in phasing out or banning some of the pesticides of greatest concern,” Trasande said. “But there are steps we can take proactively as consumers.”

USA Memory Champion on Improving One’s Memory

The American memory champion’s results give credence to the notion that (as with other things in life) you can get good at anything you practice at — including memory.

In 2009, after Nelson Dellis’s grandmother Josephine passed away from Alzheimer’s disease (which may have a hereditary component), he was inspired to find ways to keep his own brain healthy and sharp.

“I was a good student, but my memory was average,” Dellis, 35, tells CNBC Make It.

Dellis scoured the internet looking for tips to improve his memory and joined a few forums where professional “memory athletes” (people who train their memory skills for high performance) chatted about different memory techniques. Then he listened to “Quantum Memory: Learn to Improve Your Memory with The World Memory Champion,” an audiobook by Dominic O’Brien, a seven-time world memory champion.

“After that, I went off and, through trial and error, figured out what [techniques] worked well for me,” Dellis says.

Today Dellis, author of the book “Remember It” and a four-time USA Memory Champion (an annual competition for elite mental athletes), is a full-time memory coach based in Miami, Florida. He charges $250 an hour for private lessons to the likes CEOs and billionaires, including Mark Cuban and Sara Blakely.

Here are Dellis’ top three tips on improving your memory and staying sharp.

1. Go offline

Dellis says one the easiest memory tips that he’s learned over the years is to take time to totally disconnect from technology — including your smartphone — for at least an hour a day.

That’s because presence is important for memory, says Dellis.

“Your brain is a processing unit,” he says. “If your brain isn’t present to receive [information] (i.e., you’re distracted and not paying attention), how on earth do you think it’s going to be able to remember it? You’ll be surprised how powerful your natural memory is if you just try and pay attention.”

Dellis’s advice is supported by research: According to a 2017 study from the McCombs School of Business at The University of Texas at Austin, researchers found the mere presence of a smartphone reduces cognitive capacity, affecting one’s brain to hold and process data.

2. Think in pictures

“My goal whenever I memorize something is to turn it into a mental picture in my mind,” he says, which is “any mental representation of what you’re trying to memorize, using as many of your senses as possible.” It could be an association, a sound, a feeling — anything that’s “meaningful” to you, Dellis says.

That’s because it’s much easier to remember a picture of something that you are familiar with than words relating to something new and difficult, he says. (Studies in older adults have shown that pictures can help with memory.)

Dellis uses the example of remembering the name chervil (an herb) to buy at the grocery store.

“Most people might not even know what that is. So I might break that word down into what it sounds like: ‘sure-vill.’ So maybe my meaningful image could be, me saying ‘sure!’ enthusiastically to a ’vill’ain. The more context the better. Maybe I’m agreeing with this villain, because if I don’t, he’ll take all the chervil in the world and secretly garnish all the food in the world and ruin the taste of everything,” Dellis says.

The “more over-the-top and bizarre you make the image, the better.”

To practice, Dellis suggests that when you meet someone for the first time, turn their name into mental images, as he did with chervil.

“You’ll have a higher chance of remembering the person’s name, and you’ll be training your brain to get better/quicker at thinking in pictures,” he says.

3. Explore your ‘memory palace’

When you’re thinking in pictures, you need a place to store those images. So most memory athletes use a technique called the “memory palace,” according to Dellis. The technique (which dates back to the ancient Greeks) has to do with remembering things based on location

According to Dellis, a memory palace works like this: Think of a familiar place (like your house, apartment, office, etc.) and imagine a mental pathway through it. To store your images, simply imagine or “stick” each image on a location along the path in your mind. The idea is that later on when you want to retrieve the information, all you have to do is think of your memory palace, walk back through it in your mind and pick up the images you left there.

It sounds a bit crazy, but it works, according to Dellis and it allows top memory athletes to memorize thousands of pieces of information, he says.

“It’s an effective way of stringing together sets of memories because it uses more and various parts of the brain than simply short term recall (visual, emotional, language, imagination and short term memory),” neuroscientist Tara Swart tells CNBC Make It.

To practice, Dellis suggests choosing three familiar places and selecting 10 locations along your mental path through each. Start by storing daily to-do lists and grocery lists there as practice.

Joe Biden’s Weaknesses Against Trump

Joe Biden may win the popular vote against Trump, but Biden’s similarities to Hillary Clinton means that he would likely enough lose the 2020 electoral college.

Supporters of Joe Biden are unlikely to be persuaded by most of the common criticisms. They know he can be rambling and unintelligible. They know his record is unimpressive and that he doesn’t really have “policy proposals”. None of this matters, though, because to them he has the most important quality of all: he can beat Donald Trump. Nothing you can say about the former vice-president’s record, platform or mental state matters next to the argument that he is the best hope Democrats have of getting Trump out of office.

There’s just one problem: it’s a myth. It is a myth just as it was a myth that Hillary Clinton was a good candidate against Trump. Biden is not, in fact, the pragmatic choice. He would not beat Trump. He would lose. And we must say this over and over again. Forget his flubs. Forget his finger-nibbling. Biden would be crushed by Trump. If you want Trump out of office, don’t support Biden.

Last time round, Clinton supporters lived in a strange kind of denial. Anyone could see she had unique vulnerabilities Trump could exploit. She was a Wall Street candidate, and he was running to “drain the swamp”. She was under investigation by the FBI, and his pitch was that Washington was corrupt. She had supported the catastrophic Iraq war, and he portrayed himself as an outsider opponent of those wars. Trump could “run to her left” and make criticisms she would be unable to respond to, because they were accurate. Clinton’s attempts to attack Trump as an out-of-touch, reckless billionaire sex criminal would fail, because Trump would point out that she herself was out of touch, bought by billionaires and had an unrepentant alleged sex criminal as her husband and chief campaign surrogate.

Joe Biden will face many of the same problems. He has been in Washington since the age of 30, representing Delaware, the “capital of corporate America”. He is infamous for his connections to the credit card industry, and he has lied about his degree of support for the Iraq war. Even Matthew Yglesias of Vox calls Biden the “Hillary Clinton of 2020” for his corporate ties and war support. It is worth remembering what being the “Hillary Clinton” of anything means in an election against Trump.

Consider the Ukraine scandal, which is far worse for Biden electorally than usually acknowledged. Democrats have made this the centerpiece of their impeachment case against Trump, setting aside Trump’s most consequential crimes in order to focus on the charge that Trump tried to force the Ukrainian government to investigate Joe and Hunter Biden. For Democrats, the scandal is clear-cut: Trump was abusing the power of his office to “damage a political rival”. And they believe that the American people will agree, and will be disturbed by Trump’s unethical behavior. They insist there was “no evidence” that Joe Biden did anything wrong, and that Trump and his associates have been unfairly trying to smear Biden.

Democrats who think this way are walking into a buzzsaw. Let us recall: Hunter Biden was paid up to $50,000 a month by a Ukrainian oil company. Officially, the chief Ukrainian prosecutor had an open investigation into that company. Joe Biden bragged about pressuring Ukraine to fire that prosecutor, which they did. Hunter Biden says he told his father about his position in Ukraine, and Joe Biden did not ask him to step down. Joe Biden contradicts his son’s story, saying they never discussed Hunter Biden’s “work” in Ukraine. One of them is not telling the truth.

Defenders of the Bidens like to point out that the prosecutor was fired for reasons that had absolutely nothing to do with Hunter Biden. In fact, there was widespread pressure to fire the prosecutor because he wasn’t doing enough on corruption investigations, and there was a consensus among experts that this was the case. Biden’s actions had absolutely nothing to do with his son and it is ridiculous to suggest that they did.

All this is true. But the important question is: does it sound good? And the answer is: no. It sounds terrible.

One reason Democrats are bad at politics is that they concern themselves too much with facts and not enough with impressions. With Clinton’s “emails scandal”, they tried to show Clinton had not technically violated the law, but having Barack Obama’s FBI actively investigating Clinton for possible criminal wrongdoing looked terrible regardless of the facts.

Left-leaning journalists and pundits love to “fact-check” Trump, as if proving that he has lied is in itself persuasive. But 2016 should have showed us how powerless “debunking” is next to “optics”. If you have a Democratic candidate who looks really corrupt, it doesn’t matter if they’re not. People don’t trust the press and they don’t trust politicians.

Imagine Biden running against Trump. Trump will run ads like this, over and over. Good luck responding. Remember that time you have to spend defending yourself against Trump’s accusations is time not spent talking about issues that affect people’s lives. And Biden has already shown little interest in drawing people’s attention to the areas where Democrats should run strong against Trump, such as healthcare, taxation, working conditions and the climate crisis.

[…]

Ask yourself: how likely is such a candidate to win? Is such a person really the one you want to run against Trump? Look at the enthusiasm Trump gets at his rallies. It is real. Trump has fans, and they’re highly motivated. How motivated are Biden’s “fans”? Is Biden going to fill stadiums? Are people going to crisscross the country knocking on doors for him? Say what you want about Clinton, but there were some truly committed Clinton fans, and she had a powerful base of support. By comparison, Biden looks weak, and Trump is savagely effective at preying on and destroying establishment politicians.

Complicated factchecks that attempt to explain the nuances of the Ukrainian criminal prosecution system will not help Biden. People’s already limited enthusiasm for Biden will further wane, and Trump will point to his “strong economy” and “job creation” as evidence Obama and Biden were weak failures. Biden will look tired and irrelevant, and possibly forget why he is even running in the first place. Trump will be re-elected comfortably.

If there are Biden supporters in your life, you need to have serious conversations with them. Do not dwell on things that do not matter to them, like Biden’s record on bussing, or his latest nonsensical comment. Instead, keep the focus on the main argument that is sustaining his campaign: the idea that he is the best candidate to beat Trump. He isn’t. His electability is a myth, and when we look honestly at the facts we can see that Biden is actually a dangerously poor candidate to run.

Drinking Tea Regularly Linked to a Longer Life

Scientists found that there really is merit to drinking green tea.

Drinking tea at least three times a week could be linked with a longer and healthier life, scientists say.

According to new research “habitual” consumption of the hot drink is associated with lower risks of cardiovascular disease and all-cause death.

But whether the tea being consumed is green or black may make a difference.

The analysis included 100,902 participants of the China-PAR project2 with no history of heart attack, stroke, or cancer.

Participants were categorised into two groups – habitual tea drinkers, those drinking three or more times a week, and never or non-habitual tea drinkers  – those drinking less than three times a week.

They were followed-up for a median of 7.3 years, in the study published in the European Journal of Preventative Cardiology.

The research suggests a 50-year-old habitual tea drinker would develop coronary heart disease and stroke 1.41 years later, and live 1.26 years, longer than someone who never or seldom drank tea.

Compared with never or non-habitual tea drinkers, habitual tea consumers had a 20% lower risk of incident heart disease and stroke, and a 22% lower risk of fatal heart disease and stroke.

They also had a 15% decreased risk of all-cause death, the study suggests.

First author Dr Xinyan Wang, of the Chinese Academy of Medical Science in Beijing, said: “Habitual tea consumption is associated with lower risks of cardiovascular disease and all-cause death.

“The favourable health effects are the most robust for green tea and for long-term habitual tea drinkers.”

Researchers analysed the potential influence of changes in tea drinking behaviour in a subset of 14,081 participants with assessments at two time points.

The average duration between the two surveys was 8.2 years, and the median follow-up after the second survey was 5.3 years.

Habitual drinkers who maintained their habit in both surveys had a 39% lower risk of incident heart disease and stroke, 56% lower risk of fatal heart disease and stroke, and 29% decreased risk of all-cause death compared to consistent never or non-habitual tea drinkers, the study suggests.

In a sub-analysis by tea type, drinking green tea was linked with around 25% lower risks for incident heart disease and stroke, fatal heart disease and stroke, and all-cause death.

However, no significant associations were observed for black tea.

Scientists found 49% of habitual tea drinkers in the study consumed green tea most frequently, while only 8% preferred black tea.

They noted a preference for green tea in East Asia, and said the small proportion of habitual black tea drinkers might make it more difficult to observe robust associations, but that the findings hint at a differential effect between tea types.

The researchers suggest a number of reasons for this.

They indicate that green tea is a rich source of polyphenols which protect against cardiovascular disease.

While black tea is fully fermented and during this process may lose antioxidant effects.

Gunter Kuhnle, professor of nutrition and food science at the University of Reading, said: “This study is an observational study and can therefore only establish an association – not a causal relationship.”

He added that the two cups per week as cut-off point was very little when compared to the average consumption of three to four cups per day in the UK.

Prof Kuhnle said: “It is not clear from the study whether there is any benefit from higher tea intake – and therefore there is no likely benefit from increasing tea intake by the majority of the British public.”

The Dangerous Potential of War With Iran

Yesterday, U.S. bombing killed Iranian general Qasem Soleimani at Baghdad Airport in Iraq. This was an act of war ordered by the U.S. president against Iran (itself an impeachable offense since it was unconstitutionally executed without Congressional authorization). Now it’s a real possibility that the United States may soon become involved in a war with Iran. This is quite concerning for a number of reasons, one of which is that U.S. military intervention since the end of WWII has typically been disastrous for the invaded country. There’s the killing of civilians and bombing of civilian infrastructure (notably the dams) in North Korea, the Vietnam war that people there are still suffering from (estimates are that “at least 350,000 tons of live bombs and mines” remain there), and the criminal invasion of Iraq that resulted in a few hundred thousand deaths, just to name a few examples. So there’s this record of disaster for American military adventures, and there might soon be yet another one to add.

There’s also the U.S. backed overthrow of the democratically elected Iranian government in 1953, which lead to the dictatorial Shah ruling Iran until 1979. It was recently revealed through declassified documents that — surprise surprise — the reason for the U.S. doing this was for oil contracts that would benefit American oil corporations. But shouldn’t the American government be nicer to Iran based on what it did to it in the past?

It should be, but it hasn’t been. And the CIA backed overthrow may be the most significant U.S. event against Iran, but it isn’t even the only one. There are at least two more events.

One of them is when the U.S. supported Saddam Hussein’s government when it used a chemical weapons attack against Iran. As shown with the outrage over 2018’s chemical weapons attacks around Syria, it is a heinous type of attack and correctly condemned as an atrocity in war. How interesting it then is that the U.S. government knowingly supported a military that did this, and how interesting how seldom this is mentioned today.

The other event is when the U.S. shot down a civilian Iranian plane in July 1988, which killed the 290 civilians on board. The U.S. government maintained that it was an accident, and maybe it was, but it’s difficult to trust that’s the truth considering what else the U.S. was doing to Iran in the 1980s. In April 1988 for example, an engagement with Iran known as “Operation Praying Mantis” resulted in the death of two American pilots shot down with their helicopter.

In any case though, if Iran had shot down a civilian American plane with 290 civilians — including 66 children — it would clearly be an event remembered much more in America than the Iran Air Flight 655 incident is. That’s a useful thought experiment — to compare what the U.S. has done to damage other countries and try imagining a scenario where other countries did the same to the U.S.

Additionally, invading Iran isn’t like invading comparatively defenseless countries such as Afghanistan and Somalia. Iran is actually a developed country and it has a real defense system, one that’s been at $13 billion (about 2.67 percent of Iranian GDP) annually but could increase quickly. It may be defeated by the U.S. in a war, but it would put up a fight that would almost certainly lead to real direct damage to the U.S. Who wants to imagine the possibility of Iranian bombers flying over American cities?

In sum, a war with Iran is an incredibly reckless and stupid decision. If it happens, people will face significant unnecessary suffering and the world will clearly be worse off because of it.

AI Becomes Very Good at Diagnosing Breast Cancer

Artificial intelligence is becoming more of a hot topic, and people should remember more that AI can be used both to hurt humans and (as in this case) help humans.

A computer programme can identify breast cancer from routine scans with greater accuracy than human experts, researchers said in what they hoped could prove a breakthrough in the fight against the global killer.

Breast cancer is one of the most common cancers in women, with more than 2 million new diagnoses last year alone.

Regular screening is vital in detecting the earliest signs of the disease in patients who show no obvious symptoms.

In Britain, women over 50 are advised to get a mammogram every three years, the results of which are analysed by two independent experts.

But interpreting the scans leaves room for error, and a small percentage of all mammograms either return a false positive – misdiagnosing a healthy patient as having cancer – or false negative – missing the disease as it spreads.

Now researchers at Google Health have trained an artificial intelligence model to detect cancer in breast scans from thousands of women in Britain and the United States.

The images had already been reviewed by doctors in real life but unlike in a clinical setting, the machine had no patient history to inform its diagnoses.

The team found that their AI model could predict breast cancer from the scans with a similar accuracy level to expert radiographers.

Further, the AI showed a reduction in the proportion of cases where cancer was incorrectly identified – 5.7 percent in the US and 1.2 percent in Britain, respectively.

It also reduced the percentage of missed diagnoses by 9.4 percent among US patients and by 2.7 percent in Britain.

“The earlier you identify a breast cancer the better it is for the patient,” Dominic King, UK lead at Google Health, told AFP.

“We think about this technology in a way that supports and enables an expert, or a patient ultimately, to get the best outcome from whatever diagnostics they’ve had.”

Computer ‘second opinion’

In Britain all mammograms are reviewed by two radiologists, a necessary but labour-intensive process.

The team at Google Health also conducted experiments comparing the computer’s decision with that of the first human scan reader.​

If the two diagnoses agreed, the case was marked as resolved. Only with discordant outcomes was the machine then asked to compare with the second reader’s decision.

The study by King and his team, published in Nature, showed that using AI to verify the first human expert reviewer’s diagnosis could save up to 88 percent of the workload for the second clinician.

“Find me a country where you can find a nurse or doctor that isn’t busy,” said King.

“There’s the opportunity for this technology to support the existing excellent service of the (human) reviewers.”

Ken Young, a doctor who manages mammogram collection for Cancer Research UK, contributed to the study.

He said it was unique for its use of real-life diagnosis scenarios from nearly 30,000 scans.

“We have a sample that is representative of all the women that might come through breast screening,” he said.

“It includes easy cases, difficult cases and everything in between.”

The team said further research was needed but they hoped that the technology could one day act as a “second opinion” for cancer diagnoses.

Major Benefits of Reducing Air Pollution

Air pollution has for many years been a major public health problem that doesn’t receive much attention despite its significant effects on the population. It has been estimated that the majority of people in the world are regularly breathing unclean air.

Reductions in air pollution yielded fast and dramatic impacts on health-outcomes, as well as decreases in all-cause morbidity, according to findings in “Health Benefits of Air Pollution Reduction,” new research published in the American Thoracic Society’s journal, Annals of the American Thoracic Society.

The study by the Environmental Committee of the Forum of International Respiratory Societies (FIRS) reviewed interventions that have reduced air pollution at its source. It looked for outcomes and time to achieve those outcomes in several settings, finding that the improvements in health were striking. Starting at week one of a ban on smoking in Ireland, for example, there was a 13 percent drop in all-cause mortality, a 26 percent reduction in ischemic heart disease, a 32 percent reduction in stroke, and a 38 percent reduction in chronic obstructive pulmonary disease (COPD). Interestingly, the greatest benefits in that case occurred among non-smokers.

“We knew there were benefits from pollution control, but the magnitude and relatively short time duration to accomplish them were impressive,” said lead author of the report, Dean Schraufnagel, MD, ATSF. “Our findings indicate almost immediate and substantial effects on health outcomes followed reduced exposure to air pollution. It’s critical that governments adopt and enforce WHO guidelines for air pollution immediately.”

In the United States, a 13-month closure of a steel mill in Utah resulted in reducing hospitalizations for pneumonia, pleurisy, bronchitis and asthma by half. School absenteeism decreased by 40 percent, and daily mortality fell by 16 percent for every 100 ?g/m3 PM10 (a pollutant) decrease. Women who were pregnant during the mill closing were less likely to have premature births.

A 17-day “transportation strategy,” in Atlanta, Georgia during the 1996 Olympic Games involved closing parts of the city to help athletes make it to their events on time, but also greatly decreased air pollution. In the following four weeks, children’s visits for asthma to clinics dropped by more than 40 percent and trips to emergency departments by 11 percent. Hospitalizations for asthma decreased by 19 percent. Similarly, when China imposed factory and travel restrictions for the Beijing Olympics, lung function improved within two months, with fewer asthma-related physician visits and less cardiovascular mortality.

In addition to city-wide polices, reducing air pollution within the home also led to health benefits. In Nigeria, families who had clean cook stoves that reduced indoor air pollution during a nine-month pregnancy term saw higher birthweights, greater gestational age at delivery, and less perinatal mortality.

The report also examines the impact of environmental policies economically. It highlights that 25 years after enactment of the Clean Air Act, the U.S. EPA estimated that the health benefits exceeded the cost by 32:1, saving 2 trillion dollars, and has been heralded as one of the most effective public health policies of all time in the United States. Emissions of the major pollutants (particulate matter [PM], sulfur oxides, nitrogen oxides, carbon monoxide, volatile organic compounds, and lead) were reduced by 73 percent between 1990 and 2015 while the U.S. gross domestic product grew by more than 250 percent.

Given these findings, Dr. Schraufnagel has hope. “Air pollution is largely an avoidable health risk that affects everyone. Urban growth, expanding industrialization, global warming, and new knowledge of the harm of air pollution raise the degree of urgency for pollution control and stress the consequences of inaction,” he says. “Fortunately, reducing air pollution can result in prompt and substantial health gains. Sweeping policies affecting a whole country can reduce all-cause mortality within weeks. Local programs, such as reducing traffic, have also promptly improved many health measures.”

Abortion Reversal — The Dangerous Practice You’ve Probably Never Heard Of

In the United States, many more laws have been implemented that restrict or ban a woman’s ability to have an abortion. Abortion reversal is a new technique that hasn’t undergone much medical testing since the one test on it showed significant harm to the women.

Several states now require women who seek medication abortions to be provided with dubious information that the procedure could be stopped, allowing a pregnancy to continue.

But when researchers attempted to carry out a legitimate study of whether these “abortion reversal” treatments were effective and safe, they had to stop almost immediately – because some of the women who participated in the study experienced dangerous hemorrhaging that sent them to the hospital.

By passing these abortion reversal laws, “states are encouraging women to participate in an unmonitored experiment,” Creinin said.

Creinin and his colleagues detailed their concerns in a commentary in the journal Contraception, and they will publish their study in January’s edition of Obstetrics and Gynecology.

Medication abortions, which are used up to 10 weeks into a pregnancy, consist of taking two pills in sequence. The first pill in the regimen, mifepristone, loosens the pregnancy’s attachment to the uterus. The second pill, misoprostol, forces the uterus to contract to push out the pregnancy. The pills must be taken consecutively to complete the abortion, and there’s a chance the pregnancy will continue if the second pill is not taken.

A total of 862,320 abortions were provided in clinical settings in 2017, according to the Guttmacher Institute, about 39 percent of which were medication abortions. Research has shown that using these drugs is a safe way to end a pregnancy.

Some antiabortion activists and legislators claim that not taking the second pill, or giving a woman high doses of the hormone progesterone after taking mifepristone, can help stop, or “reverse,” a medical abortion.

The American College of Obstetricians and Gynecologists firmly states that “claims regarding abortion ‘reversal’ treatment are not based on science and do not meet clinical standards” and say the purported studies that underpin these antiabortion arguments lack scientific rigor and ethics.

Despite this, the claims made in these discredited studies have worked their way to antiabortion lawmakers, who in turn have put them into abortion reversal legislation that was signed by governors in North Dakota, Idaho, Utah, South Dakota, Kentucky, NebraskaOklahoma and Arkansas. The laws are currently blocked or enjoined in Oklahoma and North Dakota.

Because reliable research on these treatments is nonexistent, earlier this year, Creinin and his colleagues designed a legitimate double-blind, placebo-controlled, randomized trial that aimed to observe 40 volunteers who had already elected to have a surgical abortion.

Their goal was to see if giving progesterone to women who took the first pill in the prescribed regimen would effectively and safely halt an abortion.

After the women took the first pill in the abortion protocol, mifepristone, rather than take the second pill, misoprostol, they were either given a placebo or a dose of progesterone.

Researchers only enrolled 12 women before they had to stop the study.

Bleeding is normal during a medication abortion. But three of the women who enrolled in the UC-Davis study experienced far more serious bleeding than anyone could have anticipated when the second pill was not administered.

One woman “was so scared she called an ambulance,” while another woman startled by the amount of blood “called 911 and crawled into her bathtub”, Creinin said. A third woman who went to the emergency room needed a transfusion. One of the women had received a placebo, while two others had taken the progesterone.

Creinin and his colleagues halted the study as soon as it became clear that they could not proceed safely.

“I feel really horrible that I couldn’t finish the study. I feel really horrible that the women … had to go through all this,” Creinin said. Because the study ended prematurely, the researchers could not establish any evidence that progesterone was an effective way to stop a medication abortion.

“What the results do show, though, is that there’s a very significant safety signal” when it comes to disrupting the approved medication abortion protocol, Creinin said.

In their upcoming paper in Obstetrics and Gynecology, the researchers warn that “patients in early pregnancy who use only mifepristone may be at high risk of significant hemorrhage.”

Medical experts are so concerned about abortion reversal laws that the American Medical Association joined a lawsuit against North Dakota’s abortion reversal law, which was blocked by a federal judge in September.

The North Dakota abortion reversal law, signed by Gov. Doug Burgum (R) in March, instructed health-care providers to tell a woman “that it may be possible to reverse the effects of an abortion-inducing drug if she changes her mind, but time is of the essence” and to provide a woman with literature on how to do this. The law fails to specify what that literature would include, or what such a treatment might entail.

In 2019, 27% of Denmark’s Power Was from Wind

A model of clean energy that other countries should take note of.

COPENHAGEN, Jan 2 (Reuters) – Denmark sourced almost half its electricity consumption from wind power last year, a new record boosted by steep cost reductions and improved offshore technology.

Wind accounted for 47% of Denmark’s power usage in 2019, the country’s grid operator Energinet said on Thursday citing preliminary data, up from 41% in 2018 and topping the previous record of 43% in 2017.

European countries are global leaders in utilising wind power but Denmark is far in front of nearest rival Ireland, which sourced 28% of its power from wind in 2018 according to data from industry group WindEurope.

Across the European Union, wind accounted for 14% of consumption last year, the group says.

The higher proportion of wind energy in Denmark last year was partly due to Vattenfall starting operations at the Horns Rev 3 offshore wind farm in the North Sea in August.

The share of power from wind turbines at sea increased to 18% last year from 14% in 2018, Energinet said. Onshore wind accounted for 29% last year.

The International Energy Agency (IEA) said in October that while power generated from wind turbines at sea only accounts for 0.3% of today’s global electricity generation, capacity is set to increase 15-fold over the next two decades.

Denmark aims to reduce greenhouse gas emissions by 70% by 2030, with a new climate law passed late last year targeting an increase in the share of electricity sourced from renewable power to 100%.

Denmark, home to wind turbine giant Vestas and the world’s largest developer of offshore wind Orsted, has favourable wind conditions and began investing heavily in wind power in the 1970s.
