New method to create 'membraneless compartments' lends insight into cellular processes

A new laboratory method allows researchers to create compartments within a liquid that, like drops of oil in water, are separate but have no physical barrier between them. The method could help researchers understand how human cells use similar "membraneless compartments" to segregate and concentrate components for important cellular processes, chemical reactions, or other biological functions.

How Fear Can Spread Like a Virus

The sensations were familiar: my heart rate accelerating, my chest tightening, my focus narrowing. These were feelings I’d had many times before in my life—most often when exposed to heights, climbing a ladder or hiking along a steep trail. I’d felt them during the long, stretched-out moments of a serious car accident, rolling off the highway and into a ditch in a mountain...

Rethinking mortality and how we plan for old age

Many people dream of comfortably living out their golden years. A new study however shows that older Europeans, and especially women, frequently underestimate how many years they have left, which could lead to costly decisions related to planning for their remaining life course.

Engineered Botulinum toxin is more potent and safer in mice

Botulinum toxin (BoNT) is used for a range of applications, but when injected it can diffuse into the surrounding tissue and give rise to adverse effects. A new study shows that a subtle modification of an FDA-approved form of BoNT enhances binding to the nerve cells and improves the drug's potency and safety.

Artificial intelligence helps prevent disruptions in fusion devices

An international team of scientists led by a graduate student at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) has demonstrated the use of Artificial Intelligence (AI), the same computing concept that will empower self-driving cars, to predict and avoid disruptions—the sudden release of energy stored in the plasma that fuels fusion reactions—that can halt the...

New coronavirus stable for hours on surfaces

New research finds that the virus that causes coronavirus disease 2019 (COVID-19) is stable for several hours to days in aerosols and on surfaces. Scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable in aerosols for up to three hours, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel.

Drastic cold shot to make Americans shiver in eastern US during 1st weekend of spring

As a major storm wraps up across the north-central United States, a swath of colder and drier air will sweep in as the week ends and the weekend begins, marking an end to record-challenging warmth that will have taken hold in the East and severe weather expected to rattle the Midwest and South.The colder air will first arrive across the Midwest on Friday, squashing the severe threat in areas that...
