Researchers elucidate first 3D structure of regulator protein complex

Proteins are indispensable components in living organisms. They are not only "building material" for the body – they also make molecular communication between cells possible, they are needed for nerve impulses to occur, and they control chemical reactions.

'Genetic scissors' can give rise to unforeseen heritable mutations

CRISPR-Cas9, the "genetic scissors", creates new potential for curing diseases; but treatments must be reliable. In a new study, researchers have discovered that the method can give rise to unforeseen changes in DNA that can be inherited by the next generation.

Researchers discover mechanism behind loss of smell in people with COVID-19

Researchers have discovered a mechanism that may explain why people with COVID-19 lose their sense of smell.

Rolling brain wave patterns can provide clue to understanding sleep, anesthesia, and attention

While sleeping, the entire brain rolls through long, slow waves of electrical activity, like waves on a calm ocean. Researchers call that state of consciousness "slow wave sleep".

Study uncovers a class of microbial enzymes that drive ulcerative colitis

Ulcerative colitis, a subtype of inflammatory bowel disease, is a chronic ailment of the colon affecting nearly one million individuals in the United States. It is thought to be linked to disruptions in the gut microbiome - the bacteria and other microbes that live inside us - but no existing treatments actually target these microorganisms.

Scientists describe a smell sensory map in fruit flies

The distinctive smell of a flower.. the unmistakable aroma of coffee… the dangers linked with inhaling smoke fumes. Sensory systems have evolved to provide us with immediate, finely tuned information about the world around us, whether they are colors processed through our visual system or certain pitches interpreted through our hearing.

New nanoparticle SARS-CoV-2 vaccine shows stronger, broader, and more durable protection

The first generation of COVID-19 vaccines have been highly effective, but also have limitations: their efficacy can wane without a booster shot, and they may be less effective against some variants.

Gut bacteria transfer genes through sex to take vitamin B12, study shows

Your gut bacteria need vitamin B12 just as much as you do. Though DNA is usually passed from parent to child, new research shows gut bacteria transfer genes through "sex" in order to take their vitamins.

Study finds minimal genetic difference between healthy sea stars and those with wasting syndrome

Healthy-looking ochre sea stars have minimal genetic difference from those displaying symptoms of sea star wasting syndrome, say Oregon State University researchers who examined whether genetic variation was the reason some animals went unaffected during an epidemic of the deadly disease.

New study on mutation origination fundamentally challenges neo-Darwinism

A new study by a team of researchers from Israel and Ghana has brought the first evidence of nonrandom mutation in human genes, challenging a core assumption at the heart of evolutionary theory by showing a long-term directional mutational response to environmental pressure.
