The research uncovered 30 new genes that program stem cells to make the dendritic cells that kick-start the immune response. By uncovering this process, the researchers hope they will be able to […]

Tiny implantable tool for light-sheet imaging of brain activity — ScienceDaily


Tools that allow neuroscientists to record and quantify functional activity within the living brain are in great demand. Traditionally, researchers have used techniques such as functional magnetic resonance imaging, but this method cannot record neural activity with high spatial resolution or in moving subjects. In recent years, a technology called optogenetics has shown considerable success […]

New type of cell contributes to increased understanding of ALS — ScienceDaily


The causes of the serious muscle disease ALS still remain unknown. Now, researchers at Karolinska Institutet and KTH Royal Institute of Technology, among others, have examined a type of cell in the brain blood vessels that could explain the unpredictable disease origins and dynamics. The results indicate a hitherto unknown connection between the nervous and […]

CDC is watching for more cases of blood clots in people who got the J&J Covid vaccine


The Centers for Disease Control and Prevention (CDC) is reviewing additional reports of people who suffered severe side effects after receiving the Johnson & Johnson coronavirus vaccine. On Tuesday, the CDC and the U.S. Food and Drug Administration (FDA) suggested clinicians stop using the shot after nine reports of rare, but serious, blood clots out […]

How to make online arguments productive — ScienceDaily


The internet seems like the place to go to get into fights. Whether they’re with a family member or a complete stranger, these arguments have the potential to destroy important relationships and consume a lot of emotional energy. Researchers at the University of Washington worked with almost 260 people to understand these disagreements and to […]

Why stores should be checking CO2 levels to keep us safe


John Lewis boss Pippa Wicks was on the radio last week, reassuring the public.  As non-essential retailers threw open their doors for the first time this year, the department store, she said, had started quarantining products customers had touched for ‘a couple of days’ to allow for ‘decontamination’. While others didn’t claim to be going […]

Virologists develop broadly protective coronavirus vaccines — ScienceDaily


A candidate vaccine that could provide protection against the COVID-19 virus and other coronaviruses has shown promising results in early animal testing. The candidate coronavirus vaccines, created by Virginia Tech’s University Distinguished Professor X.J. Meng and UVA Health’s Professor Steven L. Zeichner, prevented pigs from being becoming ill with a pig coronavirus, porcine epidemic diarrhea […]

Researchers find clues to sex differences in autism — ScienceDaily


It is well established that autism occurs much more frequently in boys than in girls, and that girls seem to have a greater resilience to developing the condition. It has been unclear, however, why that is. In a new Yale-led study, researchers find that autism may develop in different regions of the brain in girls […]

Plasma device designed for consumers can quickly disinfect surfaces — ScienceDaily


The COVID-19 pandemic has cast a harsh light on the urgent need for quick and easy techniques to sanitize and disinfect everyday high-touch objects such as doorknobs, pens, pencils, and personal protective gear worn to keep infections from spreading. Now scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory and the New […]
