A new study found that 50 minutes of dry heat in an electric cooker decontaminated N95 respirators inside and out while maintaining their filtration and fit. This could enable wearers to safely reuse limited supplies of the respirators.
Dream or REM sleep is distinguished by rapid eye movement and absence of muscle tone, but electroencephalogram (EEG) recordings are indistinguishable from those of an awake brain. Neuroscientists have now found an EEG signature of REM sleep, allowing scientists for the first time to distinguish dreaming from wakefulness through brain activity alone. This could help in determining the prognosis for...

Washington's dam-busting summer is still rolling, with two more dams coming down on the Pilchuck River, opening 37 miles of habitat to salmon for the first time in more than a century.
The barrier islands of North Carolina's Cape Hatteras National Seashore are among the most popular recreational destinations on the Atlantic coast. Park managers strive to integrate the needs of wildlife with recreational use of the area's beaches, but in some cases, they impose restrictions on the latter in order to preserve the former—sometimes even completely closing portions of beaches to...
The Earth has one less asteroid to worry about thanks to the research of an international team of scientists at the Arecibo Observatory in Puerto Rico.
When it comes to training neural circuits for tissue engineering or biomedical applications, a new study suggests a key parameter: Train them young.
Researchers examined toxins in tissue concentrations and pathology data from 83 stranded dolphins and whales from 2012 to 2018. They looked at 11 different animal species to test for 17 different substances. The study is the first to report on concentrations in blubber tissues of stranded cetaceans of atrazine, DEP, NPE and triclosan. It also is the first to report concentrations of toxicants in a...

Nearly 10 years after the Tohoku-oki earthquake and tsunami devastated Japan's Fukushima Dai-ichi Nuclear Power, radiation levels have fallen to safe levels in all but the waters closest to the shuttered power plant. A new article looks at the many radioactive elements contained in the tanks and suggests that more needs to be done to understand the potential risks of releasing wastewater from the...
A new study concludes that opening clinics dedicated specifically to treating influenza can limit the number of people infected and help to 'flatten the curve,' or reduce the peak prevalence rate. While the work focused on influenza, the findings are relevant for policymakers seeking ways to reduce impacts of the ongoing COVID-19 pandemic.
Engineers have studied the simple act of shaving up close, observing how a razor blade can be damaged as it cuts human hair -- a material that is 50 times softer than the blade itself. They found that hair shaving deforms a blade in a way that is more complex than simply wearing down the edge over time.
A new analysis of ancient genomes suggests that different branches of the human family tree interbred multiple times, and that some humans carry DNA from an archaic, unknown ancestor.
A novel connection between primordial organisms and complex life has been discovered, as new evidence sheds light on the evolutionary origins of the cell division process that is fundamental to complex life on Earth.
Engineers have designed a device that replicates the lining of the colon. With the device, they can grow human colon cells along with oxygen-intolerant bacteria that normally live in the human digestive tract and have been implicated in Crohn's disease.
For the first time, a team of chemists has lifted the hood on the mechanics involved in the mysterious interplay between sunlight and molecules in the atmosphere known as 'roaming reactions', which could make atmospheric modelling more accurate.
Researchers analyzed five biomarkers present in the blood of hundreds of COVID-19 patients, finding elevated levels associated with higher odds of clinical deterioration and death.
Creative chemists employ enzymes to build a complex but promising natural anti-cancer agent called cepafungin I in a lean nine steps.
Not long after the August full moon, Florida's reefs are the scene of an annual show of sexual reproduction called the coral spawn, with coral colonies releasing masses of tiny white, pink and orange spheres into the ocean.
Already smashing records, this year's hyperactive Atlantic hurricane season is about to get even nastier, forecasters predict. In the coming months, they expect to run out of traditional hurricane names and see about twice as much storm activity as in a normal...
My friend Gerald Lincoln, the endocrinologist and naturalist who has died aged 75, devoted his life to unravelling the mysteries of nature.Brought up on a farm in Norfolk – the son of Gertrude (nee Holmes), a geography teacher, and Ernest Lincoln, a tenant farmer – he spent his childhood in the countryside, marvelling at wildlife. He also became an adept poacher, carrying toilet paper as an...
The U.S. Senate on Thursday unanimously approved a bill from Sen. Josh Hawley banning federal employees from using video-sharing app TikTok on government-issued devices, amid threats from the White House to ban the...
How a valveless embryonic heart tube pumps blood is a long-standing scientific mystery. Thanks to innovations in light-based technology, fresh insights are now available into the biomechanics of mammalian cardiogenesis—and in particular, the pumping dynamics of the mammalian tubular embryonic heart.
The first complete genome of the Asian giant hornet has been released by a team of Agricultural Research Service (ARS) scientists. ARS has made the genome available to the research community in AgDataCommons and the National Center for Biotechnology Information, even before publishing the results in a scientific journal to make the data freely accessible as quickly as possible.
