New study shows how COVID-19 response has impacted the U.S. public health system

The cruel impact of COVID-19, the virus that emerged in late 2019 and has claimed 5 million lives to date, is chronicled in daily headlines. It has robbed us of loved ones, jobs, plans and so much more.

New risk measure can better predict pandemic spread than other models

COVID-19 is not the flu. The disease caused by the novel SARS-CoV-2 virus is more transmissible, and deadlier, than most influenza epidemics we've encountered in our lifetimes, and scientists and physicians are still learning new things about the disease and its long-term effects.

Salk researchers discover how the brain ignores distracting signals to coordinate movements

As you read this article, touch receptors in your skin are sensing your environment. Your clothes and jewelry, the chair you're sitting on, the computer keyboard or mobile device you're using, even your fingers as they brush one another unintentionally - each touch activates collections of nerve cells.

Study unravels new mechanism for muscle repair after physiological damage

Muscle is known to regenerate through a complex process that involves several steps and relies on stem cells. Now, a new study led by researchers at Pompeu Fabra University (UPF, Spain)/Centro Nacional de Investigationes Cardiovasculares (CNIC, Spain)/CIBERNED (Spain) and Instituto de Medicina Molecular João Lobo Antunes (iMM, Portugal), published on 15 October in the journal Science, describes a new mechanism for muscle repair after physiological damage relying on the rearrangement of muscle fiber nuclei, and independently of muscle stem cells.

Researchers identify neurons and signaling pathways that make sexually receptive females more active

Scientists have known for a century that female animals become more active just as they are about to ovulate, a behavior that evolved to enhance their chances of mating when they are fertile.

Covid testing, turnaround times are still uneven this far into pandemic

In one recent week, a New Yorker got a free covid-19 test in a jiffy, with results the next day, while a Coloradan had to shell out $50 for a test two cities from her hometown after a frantic round of pharmacy-hopping.

Unique sound from wind farms may cause more sleep disruption than other noise sources

Residents who live within 10 km of a wind farm report more sleep issues from other sources, such as insomnia, stress and snoring spouses, than the nearby wind farms, a Flinders University study has found.

Comparing lateral flow testing with RT-PCR to detect SARS-CoV-2

Lateral flow devices (LFDs) are point-of-care tests that require significantly more time to develop than RT-PCR assays but can be used locally with minimal to no training, some of which can provide results in as little as 30 minutes. However, there have been some worries about the sensitivity of such kits. As a result, researchers from Micropathology Ltd have been comparing the two methods.
