AI helps researchers design microneedle patches that restore hair in balding mice

Hair loss is undesirable for many men — and women — because one’s hairstyle is often closely tied to their self-confidence. And while some people embrace it, others wish they could regrow their lost strands. Now, researchers reporting in ACS’ Nano... Continue Reading →

Why some people are mosquito magnets

It’s impossible to hide from a female mosquito—she will hunt down any member of the human species by tracking our CO2 exhalations, body heat, and body odor. But some of us are distinct “mosquito magnets” who get more than our... Continue Reading →

Disruption of the growth hormone receptor gene in adipose tissue results in increased lifespan in mice

A study of mice led by Ohio University Heritage College of Osteopathic Medicine and Edison Biotechnology Institute researchers has shown that stopping the activity of growth hormone (GH) in fat cells can improve health and increase lifespan. Growth hormone is... Continue Reading →

Five hours’ sleep a night linked to higher risk of multiple diseases

Getting less than five hours of sleep in mid-to-late life could be linked to an increased risk of developing at least two chronic diseases, finds a new study led by UCL researchers. The research, published in PLOS Medicine, analysed the impact... Continue Reading →

Increased thermogenesis in fat cells during active period of circadian rhythm limits weight gain in mice

A team of researchers at Northwestern University, working with a pair of colleagues from the University of Texas, has found that an increase in thermogenesis in fat cells during active periods of the daily circadian rhythm can limit weight gain... Continue Reading →

The fountain of life: Water droplets hold the secret ingredient for building life

Purdue University chemists have uncovered a mechanism for peptide-forming reactions to occur in water — something that has puzzled scientists for decades. “This is essentially the chemistry behind the origin of life,” said Graham Cooks, the Henry Bohn Hass Distinguished Professor...

Harvard team detects first definitive proof of sea level fingerprints from melting of glacial ice sheets

When glacial ice sheets melt, something counterintuitive happens to sea levels. Logic might suggest that nearby levels would rise, but instead they fall. Thousands of miles away, however, they do go up in a kind of seesaw effect. Why? The... Continue Reading →

Beyond AlphaFold: A.I. excels at creating new proteins

Over the past two years, machine learning has revolutionized protein structure prediction. Now, three papers in Science describe a similar revolution in protein design. In the new papers, biologists at the University of Washington School of Medicine show that machine learning can... Continue Reading →

A new study has concluded that there is no clear evidence that COVID-19 was transmitted from bats

A new Tel Aviv University study rejects assertions, according to which the origin of the COVID-19 outbreak is in bats. According to the study, bats have a highly effective immune system that enables them to deal relatively easily with viruses... Continue Reading →
