Medical Xpress / Blood-brain barrier scans could personalize stroke care using existing MRI data
When a person first exhibits signs of having a stroke, the timing of treatment is critical to restore blood flow to the brain and support recovery. In addition to studying and implementing ways to treat patients faster, investigators ...
Phys.org / Life with one less: Engineered bacteria break the 20-amino-acid rule
One of life's many mysteries is how it ended up choosing only a set of 20 amino acids to build proteins for its wide catalog of organisms, from single-celled bacteria to behemoth whales. From a chemical standpoint, many of ...
Phys.org / Astronomers map lifetime of over 100,000 molecular clouds across 66 galaxies
An international team of astronomers has analyzed the data from the James Webb Space Telescope (JWST) and Atacama Large Millimeter/submillimeter Array (ALMA) to investigate giant molecular clouds in nearby galaxies. The new ...
Phys.org / Sharper brains switch to a 'not what you know, but who you know' mindset online and on social media, study shows
Forming social connections online and via social media reduces how much people engage with and learn from the content posted but significantly boosts their networking performance, according to new research. The study, published ...
Phys.org / Rare footage of elusive sea-floor creatures and backward-swimming fish captured by compact video-acoustic system
Arctic glacial fjords are hotspots of marine life, yet their seafloor environments remain some of the least explored regions on Earth. Their extreme remoteness and the technical challenges of deep-water observation have led ...
Phys.org / How soil bacteria help plants defend themselves against disease
A study led by researchers at the University of Liège reveals the mechanism by which surfactin, a molecule produced by beneficial soil bacteria, activates plants' immune defenses. This mechanism, distinct from the classical ...
Phys.org / These monster black holes did not form the usual way—their history of violence is written into spacetime ripples
The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from collapsing stars, according to a new study. These cosmic giants instead build up through a series of ...
Phys.org / Team steers electron spin ballistically in graphene
Researchers at The University of Manchester's National Graphene Institute have shown that electrons in ultra-clean graphene can be steered with high precision while keeping their spin information intact, a key requirement ...
Phys.org / Babies may share adults' sense of beauty, and it appears to sharpen with age
Humans tend to be captured by things around them that they perceive as pleasurable and aesthetically pleasing. This "sense of beauty" has been widely studied extensively, mostly in experiments that involved adult participants.
Medical Xpress / Family data reveal two genetic paths to childhood depression and anxiety
Many common mental health disorders, including depression and anxiety, are associated with a tendency to internalize problems or, in other words, to direct feelings inwards instead of expressing them and sharing them with ...
Phys.org / Colored microplastics could be making global warming worse
There's more bad news about microplastics. We already know they pose a risk to health and can pollute ecosystems, but now researchers have discovered that tiny plastic particles drifting in Earth's atmosphere could be a significant ...
Phys.org / Rising temperatures could be driving up antibiotic resistance in soil, 11-year study finds
Every year, millions suffer, and thousands lose their lives to infections that were once easily treatable with the right dose of medication. The drugs are the same; human physiology is the same; the only difference is that ...
