Australian Medical Association declares climate change a health emergency

The Guardian reports: The Australian Medical Association has formally declared climate change a health emergency, pointing to “clear scientific evidence indicating severe impacts for our patients and communities now and into the future”. The AMA’s landmark shift, delivered by a motion of the body’s federal council, brings the organisation into line with forward-leaning positions taken by the American Medical Association, the British Medical Association and Doctors for the Environment Australia. The American Medical Association and the American College of Physicians…

Microbiome-drug interactions are largely being ignored by the pharmaceutical industry

Microbiome-drug interactions are largely being ignored by the pharmaceutical industry

Megha Satyanarayana reports: Matthew Redinbo remembers the day he entered the murky waters of the gut microbiome. He had popped in to say hi to Lisa Benkowski, a colleague in the Chemistry Department at the University of North Carolina at Chapel Hill. It was 2002, Benkowski had colon cancer, and she was taking a powerful chemotherapy called irinotecan. “She said the side effects were a nightmare,” Redinbo says, describing how a large number of people on the drug, marketed as…

Trump administration limits scientific input on recommendations for healthy diet

The Washington Post reports: The Trump administration is limiting scientific input to the 2020 dietary guidelines, raising concerns among nutrition advocates and independent experts about industry influence over healthy eating recommendations for all Americans. For the first time, the Department of Health and Human Services and the Department of Agriculture, which oversee the committee giving recommendations for the guidelines, have predetermined the topics that will be addressed. They have narrowed the research that can be used only to studies vetted…

The American diet is the leading cause of mortality in the U.S.

The American diet is the leading cause of mortality in the U.S.

Dariush Mozaffarian and Dan Glickman write: Americans are sick — much sicker than many realize. More than 100 million adults — almost half the entire adult population — have pre-diabetes or diabetes. Cardiovascular disease afflicts about 122 million people and causes roughly 840,000 deaths each year, or about 2,300 deaths each day. Three in four adults are overweight or obese. More Americans are sick, in other words, than are healthy. Instead of debating who should pay for all this, no…

Meditation and yoga practice linked to reduced volume in brain region tied to negative emotions

PsyPost reports: Meditation and yoga practice is associated with smaller right amygdala volume, a brain region involved in emotional processing, according to research published in Brain Imaging and Behavior. For their study, the researchers analyzed data that had been collected during the Rotterdam Study, an ongoing population-based study that has been conducted in The Netherlands since 1990. The study has recruited more than 15,000 subjects aged 45 years or over. The researchers were particularly interested in a subgroup of 3,742…

Ebola treatment breakthrough highlights Wall Street’s obsession with profit and indifference to saving lives

Barron’s reports: Monday brought a spot of good news in a bleak summer: Scientists testing Ebola drugs in the Democratic Republic of Congo found some that seemed to work. Wall Street shrugged. Scientists cut short a trial of four experimental Ebola drugs after two of them, including one developed by Regeneron Pharmaceuticals (ticker: REGN), showed extremely promising results. Ninety percent of patients who took the drugs soon after infection survived. Overall, 29% of Ebola patients dosed with Regeneron’s drug died,…

Metabolic health is inseparable from the health of our gut microbes

James Hamblin writes: The relationship between microbes and weight gain has long been overlooked in humans, but people have known about similar effects in animals for decades. After World War II, antibiotics became affordable and abundant for the first time. Farmers began giving the drugs to their livestock—for example, to treat a milk cow’s infected udder—and noticed that animals who got antibiotics grew larger and more quickly. This led to a flood of patent applications for antibiotic-laden foods for all…

The Washington Post reports: The turning point came at an evening soiree in the middle of December, when Mai Trinh spotted a friend’s luminous face amid a crowd of cocktail-quaffing party­goers. “She stood out — she looked absolutely radiant,” recalls Trinh, 44, a corporate wellness consultant and mom of three in Alexandria. “So I asked her, ‘What’s your secret, what are you doing?’ ” The secret, it turned out, was what she wasn’t doing: Trinh’s friend had decided to temporarily…

Mucus has a surprisingly wide array of beneficial biological functions

By Diana Kwon We know it best as a stringy slime dripping from noses and as viscous, discolored goop hacked up by sickened airways. But it’s so much more than that. Coating the surfaces of guts, eyes, mouth, nasal cavity and ears, mucus plays a range of important physiological roles — hydrating, cleaning, supporting good microbes and warding off foreign invaders. “I like to call it the unsung hero of the body — it’s something that has such powerful effects…

The Guardian reports: What happens to your plastic after you drop it in a recycling bin? According to promotional materials from America’s plastics industry, it is whisked off to a factory where it is seamlessly transformed into something new. This is not the experience of Nguyễn Thị Hồng Thắm, a 60-year-old Vietnamese mother of seven, living amid piles of grimy American plastic on the outskirts of Hanoi. Outside her home, the sun beats down on a Cheetos bag; aisle markers…

Lies pave the way for anti-abortion laws. To defeat the laws we must fight the lies

Lies pave the way for anti-abortion laws. To defeat the laws we must fight the lies

Comments 0 Comment

Rebecca Solnit writes: Anti-abortion laws are built on anti-abortion lies. Lies about things like who has abortions, how abortions work, how women’s bodies work and how fetuses develop. The lies pave the way for the laws. There are the old lies, like the ones suggesting that the women having abortions are careless hussies (51% of abortions are to women who were using contraception; 59% are to women who are already mothers; 75% are to poor and low-income women). Lately, there’s…

People eat at least 50,000 plastic particles a year, study finds

Comments 0 Comment

The Guardian reports: The average person eats at least 50,000 particles of microplastic a year and breathes in a similar quantity, according to the first study to estimate human ingestion of plastic pollution. The true number is likely to be many times higher, as only a small number of foods and drinks have been analysed for plastic contamination. The scientists reported that drinking a lot of bottled water drastically increased the particles consumed. The health impacts of ingesting microplastic are…

The myth of the eight-hour sleep

The myth of the eight-hour sleep

Comments 0 Comment

Stephanie Hegarty writes: We often worry about lying awake in the middle of the night – but it could be good for you. A growing body of evidence from both science and history suggests that the eight-hour sleep may be unnatural. In the early 1990s, psychiatrist Thomas Wehr conducted an experiment in which a group of people were plunged into darkness for 14 hours every day for a month. It took some time for their sleep to regulate but by…

Trevor Nace writes: The tropical blue skies over the southern Pacific Ocean were enveloped by towering mushroom clouds lingering over the Marshall Islands in 1954 as the United States continued its testing of nuclear weapons. The United States conducted 67 nuclear weapon tests from 1946 to 1958 on the pristine Marshall Islands. The most powerful test was the “Bravo” hydrogen bomb in 1954, which was about 1,000 times more powerful than the bomb dropped on Hiroshima, Japan. The extensive nuclear…

World’s rivers ‘awash with dangerous levels of antibiotics’

Comments 0 Comment

The Guardian reports: Hundreds of rivers around the world from the Thames to the Tigris are awash with dangerously high levels of antibiotics, the largest global study on the subject has found. Antibiotic pollution is one of the key routes by which bacteria are able develop resistance to the life-saving medicines, rendering them ineffective for human use. “A lot of the resistance genes we see in human pathogens originated from environmental bacteria,” said Prof William Gaze, a microbial ecologist at…
