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...
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...
Vast areas of the Martian night sky pulse in ultraviolet light, according to images from NASA's MAVEN spacecraft. The results are being used to illuminate complex circulation patterns in the Martian atmosphere
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.
A study identifies long-term storage technologies that would enhance the affordability and reliability of renewable electricity.
Researchers have developed a new type of laser beam that doesn't follow long-held principles about how light refracts and travels. The findings could have huge implications for optical communication and laser technologies.
Researchers have demonstrated that placebos reduce brain markers of emotional distress even when people know they are taking one.
Atmospheric and oceanic conditions are primed to fuel storm development in the Atlantic, leading to what could be an 'extremely active' season, according to forecasters.
Taking advantage of a total lunar eclipse, Hubble used the Moon as a mirror to study sunlight that had passed through Earth's atmosphere. As a result, Hubble detected Earth's own brand of sunscreen - ozone - in our atmosphere. The technique simulates how scientists will search for evidence of life on planets around other stars.
Bacteria are survival artists: When they get nutrition, they multiply rapidly, albeit they can also survive periods of hunger. But, when they grow too quickly, their ability to survive is hampered. This research could help increase the effectiveness of antibiotics.
LSU Health New Orleans research has unlocked a key fundamental mechanism in the communication between brain cells when confronted with stroke and found DHA not only protected neuronal cells and promoted their survival, but also helped maintain their integrity and stability.
n October 2014, the suspicion arose that the parasite worm Polydora websteri had found its way to the Wadden Sea. Researchers now confirm that they have found the shell-borer in oysters near Sylt and Texel and that it has arrived in European waters.
Researchers have identified a pattern of longer-term symptoms likely to be experienced by people who were hospitalized with the COVID-19 infection. They include fatigue, breathlessness, psychological distress -- including problems with concentration and memory -- and a general decline in quality of life.
Specifically, he pointed out that oilfield brine has much different properties, like density and viscosity, than pure water, and these differences affect the processes that cause fluid pressure to trigger earthquakes.
