Changes in a specific type of sugarlike molecule, or glycan, on the surface of cancer cells help them to spread into other tissues, according to researchers at the University of California, Davis. 

Despite increasing awareness of how critical sleep is to our health, getting a good night’s rest remains increasingly difficult in a world that’s always “on” — responding to emails at all hours, news cycles that change with every tweet and staring endlessly into the blue light of cell phone, tablet and computers screens.

In a new study, higher daily step counts were associated with lower mortality risk from all causes. 

Scientists are preparing a massive computer model of the coronavirus that they expect will give insight into how it infects in the body. 

Medical researchers have estimated some of the impacts of this summer’s bushfire smoke and air pollution on Australians’ health.

Engineers have created a tiny device that can rapidly detect harmful bacteria in blood, allowing health care professionals to pinpoint the cause of potentially deadly infections and fight them with drugs.

The virus that causes COVID-19 remains for several hours to days on surfaces and in aerosols, a new study published in the New England Journal of Medicine found.

For decades, public health officials have directed the containment of emerging pandemics – perhaps most notably – the worldwide eradication of smallpox starting in the early to mid-1960s. 

University of Massachusetts Amherst researchers have invented a portable surveillance device powered by machine learning – called FluSense – which can detect coughing and crowd size in real time, then analyze the data to directly monitor flu-like illnesses and influenza trends.

Though COVID-19 so far appears to be largely sparing children, researchers are cautioning that it is critical to understand how the virus affects kids to model the pandemic accurately, limit the disease’s spread and ensure the youngest patients get the care they need.
