Vann R. Newkirk II writes: Consider the cantaloupe. It’s a decent melon. If you, like me, are the sort who constantly mixes them up, cantaloupes are the orange ones, and honeydews are green. If you, like me, are old enough to remember vacations, you might have had them along with their cousin, watermelon, at a hotel’s breakfast buffet. Those spreads are not as bad as you remember, especially when it’s hot out; add a couple of cold bagels and a…
CNN reports: Another wave of wildfire smoke has drifted into the US, dimming blue summer skies and igniting troubling concerns regarding the increasing frequency of fires, and what they have to do with climate change. More than 100 million people are under air quality alerts from Wisconsin to Vermont and down to North Carolina as smoke from Canadian wildfires continues to waft south, though conditions are expected to improve slowly into the holiday weekend. Air quality on both sides of the border has…
Zeynep Tufekci writes: Three researchers at a laboratory in Wuhan, China, who had fallen ill in November 2019 had been experimenting with SARS-like coronaviruses under inadequate biosafety conditions, The Wall Street Journal reported on Tuesday, citing current and former U.S. officials. The Journal had reported in 2021 that some researchers at the Wuhan Institute of Virology had sought hospital care that November, around the time that evidence suggests Covid first began to spread among people. It was not publicly known,…
Discover magazine reports: Millions of years ago, our ancestors, like us today, had to contend with viruses. No doubt the infections were unpleasant for them at the time, but their suffering wasn’t for naught — some of those viruses left traces in our DNA. And, according to scientists at the Francis Crick Institute, these remnants may aid the body’s immune response to cancer today. While studying lung cancer in mice and in human tumor samples, the team found that immunotherapy…
Emily Anthes writes: In January 1912, in the depths of a New York City winter, an unusual new apartment complex opened on the Upper East Side. The East River Homes were designed to help poor families fend off tuberculosis, a fearsome, airborne disease, by turning dark, airless tenements inside out. Passageways led from the street to capacious internal courtyards, where outdoor staircases wound their way up to each apartment. Floor-to-ceiling windows opened onto balconies where ailing residents could sleep. The…
CBS News reports: Companies making so-called “forever chemicals” knew they were toxic decades before health officials, but kept that information hidden from the public, according to a peer-reviewed study of previously secret industry documents. The new study in the Annals of Global Health concluded that 3M and DuPont, the largest makers of per- and polyfluoroalkyl substances, or PFAS, actively suppressed evidence that the chemicals were hazardous since the 1960s, long before public health research caught up. “The chemical industry took…
Rolling Stone reports: After multiple miscarriages, Kiersten Hogan thought she would never be able to carry a pregnancy to term. She’d nearly given up hope when in June 2021 she learned she was pregnant. But at just 19 weeks — days after Texas’ Senate Bill 8 went into effect — Hogan woke up at 5 a.m. in excruciating pain. She called 911 and was instructed to unlock her front door and lay on the ground until EMTs arrived. “It was…
Ed Yong writes: In the 1870s, German physician Robert Koch was trying to curtail an epidemic of anthrax that was sweeping local farm animals. Other scientists had seen a bacterium, Bacillus anthracis, in the victims’ tissues. Koch injected this microbe into a mouse – which died. He recovered it from the dead rodent and injected it into another one – which also died. Doggedly, he repeated this grim process for over 20 generations and the same thing happened every time. Koch…
Christine Emba writes: At the Nation’s Gun Show in Chantilly, spirits seemed high. People wandered from booth to booth, and the scent of popcorn filled the air. It could have been mistaken for a state fair or weekend flea market were it not for the rows of weapons and accessories — gun parts, AR build kits and body armor — laid out on every surface. It was easy to overlook the one common emotion underlying the event: fear. Here were…
Mark O’Connell writes: There is plastic in our bodies; it’s in our lungs and in our bowels and in the blood that pulses through us. We can’t see it, and we can’t feel it, but it is there. It is there in the water we drink and the food we eat, and even in the air that we breathe. We don’t know, yet, what it’s doing to us, because we have only quite recently become aware of its presence; but since we have learned of it, it has become a…
Tim Vernimmen writes: This story starts in an unusual place for an article about human nutrition: a cramped, humid and hot room somewhere in the Zoology building of the University of Oxford in England, filled with a couple hundred migratory locusts, each in its own plastic box. It was there, in the late 1980s, that entomologists Stephen Simpson and David Raubenheimer began working together on a curious job: rearing these notoriously voracious insects, to try and find out whether they…
Science Alert reports: Over the last forty years or so, the number of people with diabetes has jumped from around 100 million to more than 500 million, with matching rises in associated health problems like obesity and cardiovascular disease risk. It’s a significant health problem that is getting worse, which is why researchers are investigating the underlying issues behind the trend. One of those issues is likely to be diet, according to a new study into type 2 diabetes – which accounts for 95…
W. Ian Lipkin writes: In 1999, the New York State Department of Health asked me to test brain samples from people in Queens experiencing encephalitis, or brain inflammation. Surprisingly, we found they were infected with West Nile virus, a mosquito-borne virus that had never been reported before in North America. How did a virus endemic in Africa and the Middle East end up in Queens? At the time, scientists posited that there were stowaway mosquitoes on a flight from Tel…
Live Science reports: Our “biological age,” which reflects signs of age-related decline in our cells and tissues, doesn’t steadily increase along with our chronological age. Instead, new research suggests that biological aging can accelerate during stressful events and then reverse after those events. In other words, there are measurable biological markers linked to age-related changes in cell function, and these markers can appear in times of stress and then disappear during recovery. Scientists already knew that biological age’s relationship to…
The Guardian reports: Investigators have created a 3D simulation of the Portland police bureau’s (PPB) extraordinary use of teargas during a major protest event on 2 June 2020. Forensic Architecture (FA), a research agency that investigates human rights violations, worked with weapons experts to analyze hundreds of videos from that evening, along with internal police files, invoice records, manufacturer data and photos of teargas canisters. The analysis reveals that the city’s downtown was blanketed with gas at more than 50 times the level federal regulators…
Science Alert reports: Lower temperatures might not warm your heart, but they could make for a longer life. Past research has proposed a few reasons behind this intriguing phenomenon. Now scientists from the University of Cologne in Germany have used experiments on worms to identify another possible reason: coldness drives a process through which damaged proteins are removed from cells. Several neurodegenerative diseases that can take hold as we get older – including Alzheimer’s and Parkinson’s – are linked to…
