New sensor material could enable more sensitive readings of biological signals

High-tech prosthetics, computers that are controlled by thought, the ability to walk or even move again, these are just a few of the promises of technology. Unfortunately, while the tech is — mostly — up to the challenge, getting the biology side of things to cooperate has been difficult at best, but that could change. Now, scientists have created a material that could make reading biological signals, from heartbeats to brainwaves, much more sensitive.

biomimicry

A new case study shows that biomimicry, a relatively new field that seeks to emulate nature to find solutions to human problems, can potentially expand intellectual property, increase energy savings and accelerate product innovation.

Researchers watch skin cells ‘walk’ to wounds

New research is giving a whole new meaning to feeling your skin crawl. Skin cells typically spend their entire existence in one place on your body. But researchers have seen how the cells will alter the proteins holding them in place and move to repair a wound.

A protein-RNA structure hints at how viruses commandeer human proteins

A protein-RNA structure hints at how viruses commandeer human proteins

Researchers at Case Western Reserve University and the University of Michigan have produced the first image of an important human protein as it binds with ribonucleic acid (RNA), a discovery that could offer clues to how some viruses, including HIV, control expression of their genetic material. That information could lead to new strategies to block viruses from replicating, thereby limiting or halting infection.

Types of athletic training affect how brain communicates with muscles

Types of athletic training affect how brain communicates with muscles

Using endurance training or strength and resistance training not only prepares an athlete for different types of sports, they can also change the way the brain and muscles communicate with each other.

Crystal clear images uncover secrets of hormone receptors

Crystal clear images uncover secrets of hormone receptors

Crystal clear images uncover secrets of hormone receptors

Many hormones and neurotransmitters work by binding to receptors on a cell’s exterior surface. This activates receptors causing them to twist, turn and spark chemical reactions inside cells. NIH scientists used atomic level images to show how the neuropeptide hormone neurotensin might activate its receptors. Their description is the first of its kind for a neuropeptide-binding G protein-coupled receptor (GPCR), a class of receptors involved in a wide range of disorders and the target of many drugs.

Women’s faces get redder at ovulation, but human eyes can’t pick up on it

Womans face during ovulation

Previous studies have shown that men find female faces more attractive when the women are ovulating, but the visual clues that allow this are unclear. Now, new research investigating whether it might be to do with subtle changes in skin colour has shown that women’s faces do increase in redness during ovulation, but the levels of change are just under the detectable range of the human eye.

Master protein enhances learning, memory and fitness?!

Estrogen-Related Receptor gamma protein

In this image, ERRγ is shown (stained red) in the hippocampus, the area of the brain largely responsible for memory. The new work could point to a way to enhance learning.

You’re supposed to stay fit, the key to successful aging is to be active. Science doesn’t quite understand why, but staying fit helps keep our brain in shape as we get older. I hate to run, hate it, but I exercise my brain often. Truthfully, some people seem built to run marathons and have an easier time going for miles without tiring. Other individuals might be born with a knack for memorizing things, from times tables to trivia facts. These two skills―running and memorizing―are not so different as it turns out.
