Abstract: Automatic human-posture or human-activity recognition is a very important research problem nowadays. In this work, we propose a novel human-posture recognition approach using the 3-D ...

An international research team has identified a human protein, ANKLE1, as the first DNA-cutting enzyme (nuclease) in mammals capable of detecting and responding to physical tension in DNA. This ...

An illustration shows the structure of an inhibitor bound to the active site of membrane-associated tyrosine- and threonine-specific cdc2-inhibitory kinase. An inhibitor bound to the active site of ...

Researchers reporting in ACS Energy Letters have devised a battery powered by vitamin B2 (riboflavin) and glucose. Inspired by how human bodies break down glucose for energy using enzymes, the team ...

In a new paper, scientists have reported the first successful human transplant of a kidney converted from blood type A to the universal type O using special enzymes developed at the University of ...

Modern humans are evolutionary survivors, thriving generation after generation while our ancient relatives died out. Now, new research into our brain chemistry suggests that an enzyme unique to Homo ...

Modern humans emerged roughly 300,000 years ago, but our genus Homo is much older. So what's the oldest human species on record? When you purchase through links on our site, we may earn an affiliate ...

The evolutionary success of our species may have hinged on minute changes to our brain biochemistry after we diverged from the lineage leading to Neanderthals and Denisovans about half a million years ...

Enzymes known as kinases play a critical role in cell growth, metabolism and signaling in a multitude of organisms across the tree of life—from algae to helminths to mammals. Now, scientists have ...

Apoptosis Signal-Regulating Kinase 1 (ASK1) is a pivotal member of the mitogen-activated protein kinase kinase kinase (MAP3K) family. It orchestrates cellular responses to a range of stressors—such as ...

Imagine trying to bake a cake without heat. You’ve got all the ingredients like flour, eggs and sugar, but nothing is happening. That’s what your body would be like without enzymes: potential but no ...
