Improved gut microbiota with cholesterol-lowering medication

There is a clear link between improved gut microbiota and one of our most common cholesterol-lowering drug groups: statins. This is evident from a...

Immune cell discovery could improve the fight against hepatitis B

For the first time, researchers at The Westmead Institute for Medical Research (WIMR) have identified and described a new and unique subset of human...

A team develops ‘poisoned arrow’ to defeat antibiotic-resistant bacteria

Poison is lethal all on its own — as are arrows — but their combination is greater than the sum of their parts. A...

A new hybrid fungus is found in hospitals and linked to...

From the mythical minotaur to the mule, creatures created from merging two or more distinct organisms – hybrids – have played defining roles in...

A new tool helps distinguish the cause of different types of...

In an opinion piece published in the journal Matter, members of the Fibers@MIT research group recently laid out a detailed vision for how the...

Herpes simplex virus’s VP1-2 protein can deactivate the early immune response

Herpes simplex virus (HSV1) infections are initiated at mucosal surfaces where the virus infects epithelial cells. When HSV1 spreads from the peripheral nerves and...

Ultraviolet light exposes contagion spread from improper PPE use

Despite the use of personal protective equipment (PPE), reports show that many health care workers contracted the coronavirus disease (COVID-19), which raises substantial concerns...

The electromagnetic fields may affect future medical treatments

Most electrical activity in vertebrates and invertebrates occurs at extremely low frequencies, and the origin — and medical potential — of these frequencies have...

3D-printable medical mask inspired by the nasal structures of animals

A multi-institution team, including a Cornell researcher, has received a National Science Foundation grant to design an open-source, 3D-printable medical mask inspired by the...

Investigators want to find out how COVID-19 is causing heart failure

It’s well-known that COVID-19 affects the respiratory system, infecting healthy lung cells with the COVID-19 virus, but if it spreads to the heart it...

Two mechanisms underpinning how the heart influences our perception

Heart and brain communicate constantly. For example, when we encounter a dangerous situation, signals from the brain make sure that the heart beats faster....

Study reveals the most important flowering plants sources for honey bees
