Common diabetes drug helps chickens lay more eggs

What do chickens and people with a common reproductive disorder have in common? More than one might think — and a widely-used diabetes medication might just be the surprising link. At Penn State, researchers discovered that metformin, a drug usually prescribed for type 2 diabetes and polycystic ovary syndrome (PCOS) in humans, can actually help […]

Could nanoplastics in the environment turn E. coli into a bigger villain?

Nanoplastics are everywhere. These fragments are so tiny they can accumulate on bacteria and be taken up by plant roots; they’re in our food, our water, and our bodies. Scientists don’t know the full extent of their impacts on our health, but new research from University of Illinois Urbana-Champaign food scientists suggests certain nanoplastics may […]

Novel molecular maneuver helps malaria parasite dodge the immune system

Researchers at Weill Cornell Medicine have discovered how a parasite that causes malaria when transmitted through a mosquito bite can hide from the body’s immune system, sometimes for years. It turns out that the parasite, Plasmodium falciparum, can shut down a key set of genes, rendering itself “immunologically invisible.” “This finding provides another piece of […]

How antibiotic resistance to fusidic acid works

In a new article published in Nature Communications, researchers from Uppsala Antibiotic Center, Uppsala University and SciLifeLab describe a fundamental mechanism of antibiotic resistance. What happens in a bacterium that is resistant to the antibiotic fusidic acid? With a stop-motion movie at the atomic level, they can show that the resistance protein FusB works nearly […]

World’s largest bat organoid platform paves the way for pandemic preparedness

Did you know that more than 75% of new infectious diseases affecting humans originally come from animals? Bats, in particular, are natural hosts to some of the world’s most dangerous viruses, including those responsible for COVID-19 (SARS-CoV-2), MERS-CoV, influenza A, and hantavirus outbreaks. Yet, despite their importance, scientists have long struggled to study how these […]

Genome of near-extinct northern white rhino offers hope for reviving the species

The northern white rhinoceros is one of the rarest animals on Earth, with just two females left and no natural way for the species to reproduce. Now, an international team of scientists at Scripps Research, the San Diego Zoo Wildlife Alliance, Max Planck Institute for Molecular Genetics, and other collaborators have mapped the entire genome […]

A plant you’ve never heard of can do what scientists once thought impossible

About 3.7 billion years ago, a string of naturally occurring amino — the same kind that astronomers have found in meteorites and just recently in a stellar nursery near the center of the Milky Way Galaxy — reacted with a naturally occurring catalyst and began the fateful process of self-assembled replication. One of the most […]

From prehistoric resident to runaway pet: First tegu fossil found in the U.S.

Originally from South America, the charismatic tegu made its way to the United States via the pet trade of the 1990s. After wreaking havoc in Florida’s ecosystems, the exotic lizard was classified as an invasive species. But a recent discovery from the Florida Museum of Natural History reveals the reptiles are no strangers to the […]

A coordinated kinase and phosphatase network regulates Stu2 recruitment to yeast kinetochores

Cells coordinate diverse events at anaphase onset, including separase activation, cohesin cleavage, chromosome separation, and spindle reorganization. Regulation of the XMAP215 family member and microtubule polymerase, Stu2, at the metaphase-anaphase transition determines a redistribution from kinetochores to spindle microtubules. We show that cells modulate Stu2 kinetochore-microtubule localization by Polo-like kinase1/Cdc5-mediated phosphorylation of T866, near the […]
