Surprising gut protein discovery is new target for constipation treatment

Researchers in Australia have discovered that a touch-sensitive protein normally found in skin is also located in the gut. There, it seems to sense the presence of food and triggers contractions to push it along, while reduced levels of this protein ma… Continue reading Surprising gut protein discovery is new target for constipation treatment

Genetic study reveals causal link between blood type and COVID severity

The large genetic study has affirmed prior observations linking persons with type A blood to increased risk of severe COVID-19

Very early in the pandemic doctors began tracking the association between COVID-19 disease severity and a patient’s blood type. Now researchers have validated those early observations, finding several blood proteins are causally linked to an increased risk of hospitalization and death from COVID-19.

Protein tweak makes CRISPR gene editing 4,000 times less error-prone

The CRISPR gene-editing system is a powerful tool that could revolutionize medicine and other sciences, but unfortunately it has a tendency to make edits to the wrong sections of DNA. Now, researchers at the University of Texas at Austin have identifie… Continue reading Protein tweak makes CRISPR gene editing 4,000 times less error-prone

Promising new drug target to treat diabetes and other metabolic diseases

A new preclinical study has demonstrated how an experimental drug can treat type 2 diabetes by increasing the expression of a recently discovered protein found to influence insulin signaling in cells. Across several mouse studies, the research shows th… Continue reading Promising new drug target to treat diabetes and other metabolic diseases

Restoring a deficient “motor” protein could improve fertility success

The leading cause of miscarriage is that human eggs are surprisingly bad at managing the number of chromosomes in them. But now, researchers at the Max Planck Institute have identified a motor protein that helps this process function smoothly, leading … Continue reading Restoring a deficient “motor” protein could improve fertility success

Artificial muscles made of human proteins make for better implants

Researchers have developed a new type of artificial muscle that’s entirely made out of natural proteins. Responding to changes in its environment allows the muscle to flex on demand, which could make it useful for implants, prosthetics or robotics.Cont… Continue reading Artificial muscles made of human proteins make for better implants

Glowing nanoantennas made of DNA spy on proteins in action

Examining the tiny world of proteins is tricky, but researchers at the Université de Montréal have developed a new tool that can let scientists peer closer, aiding study of disease and drug development. The team used DNA to create nanoantennas that flu… Continue reading Glowing nanoantennas made of DNA spy on proteins in action

Fungus-made protein may be an eco-friendly alternative to egg whites

Egg white powder is a very widely used food ingredient, which means that a lot of hens have to be raised on a lot of farms, consuming a lot of feed and producing a lot of waste. There may soon be a greener alternative, however, thanks to a fungus which… Continue reading Fungus-made protein may be an eco-friendly alternative to egg whites
