The ocean plastic we can’t see

The ocean plastic we can’t see

The Guardian reports: Every year, 8m tons of plastic enters the ocean. Images of common household waste swirling in vast garbage patches in the open sea, or tangled up with whales and seabirds, have turned plastic pollution into one of the most popular environmental issues in the world. But for at least a decade, the biggest question among scientists who study marine plastic hasn’t been why plastic in the ocean is so abundant, but why it isn’t. What scientists can…

Microplastic pollution has contaminated the whole planet

Microplastic pollution has contaminated the whole planet

The Guardian reports: Microplastic pollution is raining down on city dwellers, with research revealing that London has the highest levels yet recorded. The health impacts of breathing or consuming the tiny plastic particles are unknown, and experts say urgent research is needed to assess the risks. Only four cities have been assessed to date but all had microplastic pollution in the air. Scientists believe every city will be contaminated, as sources of microplastic such as clothing and packaging are found…

‘There’s something terribly wrong’: Americans are dying young at alarming rates

The Washington Post reports: Death rates from suicide, drug overdoses, liver disease and dozens of other causes have been rising over the past decade for young and middle-aged adults, driving down overall life expectancy in the United States for three consecutive years, according to a strikingly bleak study published Tuesday that looked at the past six decades of mortality data. The report, published in the Journal of the American Medical Association, was immediately hailed by outside researchers for its comprehensive…

Ruthless quotas at Amazon are maiming employees

Ruthless quotas at Amazon are maiming employees

The Atlantic reports: When Candice Dixon showed up for her first day of work at an Amazon warehouse in Eastvale, California, she stepped into a wonder of automation, efficiency, and speed. Inside the sprawling four-story building in Southern California’s Inland Empire, hundreds of squat orange robots whizzed across the floor, carrying tall yellow racks. As a stower, her job was to stand in a spot on the floor, like hundreds of others in that million-square-foot warehouse, and fill an unending…

The climate change health risks facing a child born today: A tale of two possible futures

The climate change health risks facing a child born today: A tale of two possible futures

Inside Climate News reports: A child born today faces two possible futures. In one, the world continues to burn fossil fuels, making the child more likely to develop asthma from air pollution, at greater risk of vector-borne diseases, and more vulnerable to anxiety as extreme weather events threaten his community. In the other, those risks are diminished because the world has responded quickly and adequately to climate change, with a large-scale shift away from fossil fuels. These two, starkly different…

EPA to limit science used to write public health rules

EPA to limit science used to write public health rules

The New York Times reports: The Trump administration is preparing to significantly limit the scientific and medical research that the government can use to determine public health regulations, overriding protests from scientists and physicians who say the new rule would undermine the scientific underpinnings of government policymaking. A new draft of the Environmental Protection Agency proposal, titled Strengthening Transparency in Regulatory Science, would require that scientists disclose all of their raw data, including confidential medical records, before the agency could…

We are running out of unpolluted air

We are running out of unpolluted air

The Atlantic reports: Officials have implored the people of New Delhi to stay inside, indefinitely. Five million children in India’s capital have been handed face masks. Everyone is to keep windows closed. Contrary to the most fundamental medical advice, the city’s chief minister urged residents this week to “avoid outdoor physical activities.” News images seem cut from an apocalyptic outbreak film. One of India’s holiest rivers is covered in toxic foam that looks like white cotton candy. Midday visibility is…

The EPA disbanded our clean air science panel. We met anyway – and found that particle pollution regulations aren’t protecting public health

The EPA disbanded our clean air science panel. We met anyway – and found that particle pollution regulations aren’t protecting public health

Vehicles are a major source of particulate air pollution. Deliris/Shutterstock By H. Christopher Frey, North Carolina State University Since 1980, emissions of six common air pollutants have decreased by 67%, thanks largely to government regulation. At the same time, U.S. gross domestic product has increased by 165%. While some assert that regulation acts as a drag on the economy, this record indicates that environmental protection does not have to undercut economic growth. I have studied air pollution and air quality…

Mapping the human oral microbiome

Mapping the human oral microbiome

In an interview with Knowable Magazine, Floyd Dewhirst says: We don’t really know the number of bacteria in an average mouth. But there are something like 1011 [100 billion] organisms per gram of plaque — so we’re looking at a large number. What people usually talk about is how many species are in there. The Human Oral Microbiome Project identified a little over 700 different species of bacteria. (There are also fungi and viruses.) About 400 of the 700 bacterial…

EPA set to revoke restrictions on toxic metals poisoning drinking water

EPA set to revoke restrictions on toxic metals poisoning drinking water

The New York Times reports: The Trump administration is expected to roll back an Obama-era regulation to limit dangerous heavy metals like arsenic, lead and mercury from coal-fired power plants, according to two people familiar with the plans. With a series of new rules expected in November, the Environmental Protection Agency will move to weaken the 2015 regulation by relaxing some of the requirements on power generators and also exempting a significant number of power plants from even those requirements….

Explaining illness with belief in evil

Explaining illness with belief in evil

Live Science reports: Where did the spiritual concept of evil originate? One possible explanation might be people’s attempts to understand and cope with infectious diseases. Linking diseases and their symptoms to mysterious evil forces is a practice that emerged in traditional belief systems prior to the mid-19th century, when germ theory was introduced, scientists wrote in a new study. Germ theory revealed that microscopic pathogens, rather than malevolent spirits, were the cause of illness. However, the connection between religious convictions…

One skill that doesn’t deteriorate with age

One skill that doesn’t deteriorate with age

Reading and writing can prevent cognitive decline. AJP/Shutterstock.com By Roger J. Kreuz, University of Memphis When Toni Morrison died on Aug. 5, the world lost one of its most influential literary voices. But Morrison wasn’t a literary wunderkind. “The Bluest Eye,” Morrison’s first novel, wasn’t published until she was 39. And her last, “God Help the Child,” appeared when she was 84. Morrison published four novels, four children’s books, many essays and other works of nonfiction after the age of…

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…
