There’s absolutely no positively justifiable reason that fossil fuels should still be used anywhere near their levels today, and this is another reason why.
As many as 153 million premature deaths linked to air pollution could be avoided worldwide this century if governments speed up their timetable for reducing fossil fuel emissions, a new Duke University-led study finds.
The study is the first to project the number of lives that could be saved, city by city, in 154 of the world’s largest urban areas if nations agree to reduce carbon emissions and limit global temperature rise to 1.5°C in the near future rather than postponing the biggest emissions cuts until later, as some governments have proposed.
Premature deaths would drop in cities on every inhabited continent, the study shows, with the greatest gains in saved lives occurring in Asia and Africa.
The new projections underscore the grave shortcomings of taking the lowest-cost approach to emissions reductions, which permits emissions of carbon dioxide and associated air pollutants to remain higher in the short-term in hopes they can be offset by negative emissions in the far distant future, said Drew Shindell, Nicholas Professor of Earth Sciences at Duke’s Nicholas School of the Environment.
“The lowest-cost approach only looks at how much it will cost to transform the energy sector. It ignores the human cost of more than 150 million lost lives, or the fact that slashing emissions in the near term will reduce long-term climate risk and avoid the need to rely on future carbon dioxide removal,” he said. “That’s a very risky strategy, like buying something on credit and assuming you’ll someday have a big enough income to pay it all back.”
Air pollution has also been found recently to have links to cognitive impairment in children.
It has only been tried in mice thus far, yet the drug shows promise at treating a real problem of socialization.
Low doses of a compound called romidepsin might help those on the autism spectrum overcome the social challenges that define their condition.
So far it has only been shown to be effective in mice, but the mechanisms behind the drug’s activity make it a promising candidate for an autism treatment in humans – the first of its kind.
Autism spectrum disorder (ASD) is an umbrella term for traits that interfere with the brain’s ability to process stimuli and negotiate social cues, often making communication difficult.
Of course mice aren’t people, but since the mechanisms appear to be the same, there’s hope that the drug’s effects will be as well.
The fact it’s already FDA approved also suggests a treatment is tantalizingly on the horizon.
It’s important to keep in mind that there’s still plenty of research between this study and a publicly available treatment.
Yet another sick and disturbing part of what has happened to the American federal government over the last year. It’s disturbing to know how many people still support the immensely harmful Trump regime — as it continually enacts policies against their interests (such as the latest corporate welfare package for Wall Street) no less.
Instead of appointing scientists or conservation experts, the International Wildlife Conservation Council is composed almost entirely of celebrity hunting guides, representatives from rifle and bow manufacturers and, of course, wealthy trophy hunters who like to boast about all of their “Big Five” souvenirs.
After reviewing the backgrounds of the new council’s 16 board members, The AP found ten members of the council are high-profile members of Safari Club International, which is a hunting organization that lobbied hard against the (recently overturned) federal ban on elephant and lion trophy imports.
Yet several recent studies have suggested trophy hunting leaves already vulnerable animal populations significantly weakened. Even still, with such a one-sided council, it seems inevitable that the wildlife advisory council will come to the same conclusion as Zinke.
The story of damaging vulnerable animal populations often means that humans miss valuable potential insights about them. There are countless examples of these insights being beneficial, from venom being used to create medicine to the study of bats leading to the development of radar.
An important finding through studying animals reveals itself again, and the fight against antibiotic resistance is among the most serious issues of the 21st century.
Researchers previously discovered that platypus milk confers antimicrobial protection to the species’ young, and now a new study led by scientists at Australia’s CSIRO has figured out what it is about platypus milk that’s so effective against bacteria.
“Platypus are such weird animals that it would make sense for them to have weird biochemistry,” says one of the team, molecular biologist Janet Newman.
“By taking a closer look at their milk, we’ve characterised a new protein that has unique antibacterial properties with the potential to save lives.”
It’s possible, the team thinks, the platypus evolved to produce its antimicrobial Shirley Temple curls, as a defence against bacteria attracted to this exposed milk, ensuring the pups got fed, not bugs in the environment.
That’s just a hypothesis at the moment, but now that we know about the molecular structure of this natural antimicrobial structure, the team says we might be able to replicate the protein for antibiotic medications – providing us with a new means of fighting the growing scourge of antibiotic resistance.
It’s not the first time this unusual animal has come to our aid. In 2016, researchers discovered a hormone contained in platypus venom could actually help us develop new kinds of diabetes treatments.
Not bad for a wacky hybrid of stitched-together animal parts that’s probably just a joke somebody’s playing on us. Not bad at all.
“There’s a quote from [Louis] Pasteur which is ‘Chance favours the prepared mind’,” Newman told Radio NZ.
“You can find discoveries in all sorts of places.”
Harmful algal blooms are often caused by nutrient pollution via overused chemicals such as phosphorous. These algal blooms regularly represent threats to water-based freshwater ecosystems, and so it’s useful that a solution to this problem is being introduced more.
A cheap, safe and effective method of dealing with harmful algal blooms is on the verge of being introduced following successful field and lab tests.
Moves to adopt use of hydrogen peroxide (H2O2) as an effective treatment against toxic algae are already underway following the results of new research by a team from the John Innes Centre and the University of East Anglia (UEA.)
Successful trials last summer showed that H2O2 was effective against the golden algae, Prymnesium parvum. This is responsible for millions of fish kills worldwide each year and a threat to the £550m economy of the Broads National Park where trials are taking place.
Now follow up lab tests have demonstrated that controlled doses of the versatile chemical compound could be even more effective in dealing with cyanobacteria commonly known as blue green algae — a major public health hazard and potentially fatal to dogs and livestock.
Some of these exciting results are published today in the journal Biochemical Society Transactions along with a series of other scientific developments related to algal communities in the Broads National Park; one of the UK’s most popular and environmentally important network of waterways.
Dr Ben Wagstaff, one of the authors of the study from the John Innes Centre said: “We’ve demonstrated that the use of hydrogen peroxide is a practical, relatively easy way of managing these blooms.
“Work has already started to put together protocols for the use of hydrogen peroxide to control Prymnesium and our research showed that blue green algae are even more susceptible. You can potentially use even lower doses to wipe out blue-green blooms.”
The work in the Broads National Park could have widespread implications for the way harmful algal blooms are managed in waterways worldwide.
The Cloud Act would allow for dangerous violations of consumer privacy rights through abusing the stored data corporations have on people. U.S. citizens, I encourage you to oppose this type of legislation. Privacy rights are going to become much more important in the next several years ahead as more and more of society is effused with technological infrastructure.
Civil libertarians and digital rights advocates are alarmed about an “insidious” and “dangerous” piece of federal legislation that the ACLU warns “threatens activists abroad, individuals here in the U.S., and would empower Attorney General Sessions in new disturbing ways.”
The Clarifying Lawful Overseas Use of Data or CLOUD Act (S. 2383 and H.R. 4943), as David Ruiz at Electronic Fronteir Foundation (EFF) explains, would establish a “new backdoor for cross-border data [that] mirrors another backdoor under Section 702 of the FISA Amendments Act, an invasive NSA surveillance authority for foreign intelligence gathering” recently reauthorized by Congress.
Ruiz outlines how the legislation would enable U.S. authorities to bypass Fourth Amendment rights to obtain Americans’ data and use it against them:
The CLOUD Act allows the president to enter an executive agreement with a foreign nation known for human rights abuses. Using its CLOUD Act powers, police from that nation inevitably will collect Americans’ communications. They can share the content of those communications with the U.S. government under the flawed “significant harm” test. The U.S. government can use that content against these Americans. A judge need not approve the data collection before it is carried out. At no point need probable cause be shown. At no point need a search warrant be obtained.
The EFF and ACLU are among two dozen groups that banded together earlier this month to pen a letter to Congress to express alarm that the bill “fails to protect the rights of Americans and individuals abroad, and would put too much authority in the hands of the executive branch with few mechanisms to prevent abuse.”
“This controversial legislation would be a poison pill for the omnibus spending bill,” declared Fight for the Future’s deputy director, Evan Greer. “Decisions like this requires rigorous examination and public debate, now more than ever, and should not be made behind closed doors as part of back room Congressional deals.”
The group also pointed out that big tech companies such as Apple, Facebook, and Google are among those lobbying lawmakers to include the CLOUD Act in the spending bill:
As 2017 showed, hurricanes can do immense damage. The effects of climate change will also make hurricanes worse, as warmer air means more water vapor, and more water vapor translates to more superstorms. It’s uncertain how much using air bubble technology would actually help, but there might be beneficial truth to using it.
Tropical hurricanes are generated when masses of cold and warm air collide. Another essential factor is that the sea surface temperature must be greater than 26.5°C.
“Climate change is causing sea surface temperatures to increase,” says Grim Eidnes, who is a Senior Research Scientist at SINTEF Ocean. “The critical temperature threshold at which evaporation is sufficient to promote the development of hurricanes is 26.5°C. In the case of hurricanes Harvey, Irma and Maria that occurred in the Gulf of Mexico in the period August to September 2017, sea surface temperatures were measured at 32°C”, he says.
So to the big question. Is it possible to cool the sea surface to below 26.5°C by exploiting colder water from deeper in the water column?
Researchers at SINTEF now intend to save lives by using a tried and tested method called a “bubble curtain”.
The method consists of supplying bubbles of compressed air from a perforated pipe lowered in the water, which then rise, taking with them colder water from deeper in the ocean. At the surface, the cold water mixes with, and cools, the warm surface water.
SINTEF believes that the Yucatan Strait will be an ideal test arena for this technology.
“Our initial investigations show that the pipes must be located at between 100 and 150 metres depth in order to extract water that is cold enough” says Eidnes. “By bringing this water to the surface using the bubble curtains, the surface temperature will fall to below 26.5°C, thus cutting off the hurricane’s energy supply”, he says, before adding that “This method will allow us quite simply to prevent hurricanes from achieving life-threatening intensities”.
