A team of biochemists and virologists at Goethe University and the Frankfurt University Hospital were able to observe how human cells change upon infection with SARS-CoV-2, the virus causing COVID-19 in people. The scientists tested a series of compounds...
It's not exactly the set of TV's "American Ninja Warrior," but a tiny obstacle course for bacteria has shown researchers how E. coli changes its behavior to rapidly clear obstructions to food. Their work holds implications for not only biology and...
To the heroes among you who eat the whole apple: besides extra fiber, flavonoids and flavor, you're also quaffing 10 times as many bacteria per fruit as your core-discarding counterparts. Is this a good thing? Probably. But it might depend...
A grape variety still used in wine production in France today can be traced back 900 years to just one ancestral plant, scientists have discovered. With the help of an extensive genetic database of modern grapevines, researchers were able to...
The artificial cells could be used to sense changes in the body and respond by releasing drug molecules, or to sense and remove harmful metals in the environment. Responding to chemical changes is a crucial function of biological cells. For example, cells...

Discovery of a new feature of a large class of pathogenic viruses may allow development of new antiviral medications for the common cold, polio, and other illnesses, according to a new study publishing June 11 in the open-access journal PLOS...
The secret to making clothing practically indestructible could be the same thing that makes us grow out of it: sugar. A new discovery from the University of Virginia School of Medicine reveals how sugars could be used to make almost...

One of the largest living birds, the Southern Cassowary, has a simple throat structure similar to the fellow Australian emu. Now new research confirms a common link between the cassowary and small flighted South American tinamou—and even the extinct...
Drug-resistant bacteria responsible for deadly hospital-acquired infections shut out antibiotics by closing tiny doors in their cell walls. The new finding by researchers at Imperial College London could allow researchers to design new drugs that 'pick the locks' of these closed doors...
