Desert alga reveals how fast growth and resistance to extreme conditions can coexist
A single-celled green alga from the sand dunes of the Negev Desert has, within just a few years, become a key model organism in modern photosynthesis research....
Viral enzyme cuts bacterial sensor protein, triggering defense against invading phages
In the fight to find better treatments for bacterial infections, one rapidly evolving therapy uses a group of viruses called bacteriophages (phages). Phages can...
Precisely patterned molecular threads boost neuron growth and synapse formation in cell cultures
Northwestern University scientists have developed remarkably long, precisely patterned molecular threads that could open new possibilities for designing advance...
Growth in milk boosts Staph bacteria's resistance to antibiotics, experiments reveal
Staphylococcus aureus is frequently found in human and veterinary infections. It is named for the golden-yellow pigment it produces, which contributes to its vi...
Sea change: WildFin aims to improve fish behavior analysis in the wild
In the first year of her doctoral research, Abigail Grassick collected hours of underwater video as she studied fish communities living on bommies—individual cl...
Fluent in two languages? It comes at a cost to emotional regulation (but don't worry)
Say "I'm angry" out loud, and your brain reacts to it, reducing the use of emotional brain regions. But this trick does not work if you say it in your second la...
In Alaska, soil in permafrost regions is warming the fastest
Soils are warming quickly and at considerable depth across Alaska, with temperatures rising fastest in the state's permafrost region, a trend that could acceler...
Teen sexting: Why 'just say no' fails
Blunt warnings telling teenagers not to share sexual images are failing to protect them and can make victims of image-based sexual abuse feel blamed, ashamed an...
Largest-ever jaguar analysis identifies how populations are connected across the Americas
An international team of researchers has produced the most comprehensive assessment to date of connectivity across the jaguar's range, identifying key habitats...
Urban environments may be the ultimate training grounds for invasive species
As cities grow and urban sprawl expands, could these changing landscapes be giving invasive species a competitive edge? Scientists at the University of Florida...
Hazelwood redevelopment suggests neighborhood investment can advance without typical displacement pressures
Neighborhood investments meant to improve housing and opportunity often spark fears of gentrification and displacement. That worry is playing out in Pittsburgh'...
Sex-like DNA exchange in starving bacteria occurs over 100 times more often than spontaneous mutations
How do bacteria adapt when resources run low? ISTA researchers have found that, under starvation stress, E. coli can use bacteriophages and CRISPR-Cas immunity...
