Unprecedented videos show RNA switching 'on' and 'off'

Similar to a light switch, RNA switches (called riboswitches) determine which genes turn "on" and "off." Although this may seem like a simple process, the inner workings of these switches have confounded biologists for decades.

Walking efficiently takes next to no thought

Whether walking beside a lake or clambering a mountain, people adjust their strides to use the least energy possible. "People are continuously sensing their energy expenditure and adapting their gait to minimize costs," says ...

Why older people should chill when it's hot out

Taking a break from extreme heat, by visiting a cooling center for example, could help our cells protect themselves from damage, according to preliminary findings from a new study. The research, which focused on older people, ...

The molecular imaging behind COVID-19 breakthroughs

It's fair to say that before the COVID-19 pandemic, very few non-scientists could name a viral protein. But now, millions of people around the world can name the SARS-CoV-2 spike protein, and a subset of those could probably ...

Dozens of mammals could be susceptible to SARS-CoV-2

Numerous animals may be vulnerable to SARS-CoV-2, the virus that causes COVID-19, according to a large study modelling how the virus might infect different animals' cells, led by UCL researchers.

New technique takes 3-D imaging an octave higher

A collaboration between Colorado State University and University of Illinois at Urbana-Champaign resulted in a new, 3-D imaging technique to visualize tissues and other biological samples on a microscopic scale, with potential ...
