Pregnant women who develop severe COVID-19 infections that require hospitalization for pneumonia and other complications may not be more likely to die from these infections than non-pregnant women. In fact, they may have...

COVID-19 patients who receive oxygen therapy or experience fever show reduced gray matter volume in the frontal-temporal network of the brain, according to a new study. The study's findings demonstrate changes to the fro...

Researchers report that they have built what they say is the world's smallest single-chip system, consuming a total volume of less than 0.1 mm3. The system is as small as a dust mite and visible only under a microscope. ...

Gray matter was reduced in areas of the frontal gyri of patients with COVID-19. Significant gray matter reductions were seen in those who received oxygen therapy and in those who reported fever. The findings suggest coro...

People with a poor sense of smell are 50% more likely to be hospitalized for pneumonia than those with a good sense of smell.

Phase precession plays a critical role in the human brain. Not only does it link sequential positions, but it also plays a role in abstract progression to a specific goal.

Simon Fraser University researchers have designed a remarkably fast engine that taps into a new kind of fuel--information.

A new study has identified a scent receptor in mosquitoes that helps them sniff out and avoid trace amounts of pyrethrum, a plant extract used for centuries to repel biting insects. These findings could help researchers ...

New research shows that individuals living with human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) -- an estimated 38 million worldwide, according to the World Health Organization -- have a...

A new study reports the number of people reporting chronic pain is rising across every age group and demographic.

Neurological symptoms associated with COVID-19, from losing the sense of smell to stroke, are linked to a six-fold higher risk of dying as a result of coronavirus.
