Medical Xpress / Smoking during pregnancy linked to smaller visual cortex in two populations
We tend to think of a fetus's brain as a construction site guided by a blueprint imprinted in the genes. But even before birth, other things are happening. The fetus moves, responds to muffled sounds, receives stimuli and, ...
Phys.org / How calcium channels in muscle cells open together
Every step we take begins with a burst of calcium inside our muscle cells, causing them to contract. To prepare for action, the cells keep calcium locked in an internal compartment, the sarcoplasmic reticulum. Studding its ...
Phys.org / AI-guided mutations help viruses infect bacteria up to 1 million times more effectively
Biochemists at the University of Wisconsin–Madison are using AI to tackle one of modern medicine's most pressing challenges: the rise of antibiotic-resistant bacterial infections. Using data collected in their lab, biochemistry ...
Medical Xpress / AI assistant learns from radiology reports to spot problems in abdominal scans
An abdominal CT scan packs an extraordinary amount of information into a single image, layering dozens of organs and hundreds of possible conditions. It's widely considered one of the most complex scans in medicine to read, ...
Phys.org / Monumental baths reveal where pilgrims may have purified themselves before entering Jerusalem's Temple
A monumental complex of ritual baths, most likely used by Jewish pilgrims visiting the Temple in Jerusalem, has been uncovered at the foot of the Temple Mount. Dating to the late Second Temple period (first century BCE–70 ...
Phys.org / Bronze Age migration in Greece largely involved young adults, skeletal samples suggest
Young adults, not families, drove migration in Bronze Age communities. Using skeletal samples from archaeological sites in Greece, researchers mapped mobility during the region's Middle and Late Bronze Age. The study suggests ...
Phys.org / Frog's coat of bacterial armor helps protect it from fungal disease
The bacteria living on frogs' skin could play a vital role in protecting the animals from a deadly fungal disease. A team of researchers led by Penn State scientists found that frogs' natural skin bacteria can help them fight ...
Phys.org / Ningaloo Reef corals reveal early fall spawning window for two key species
Curtin University scientists have uncovered an important missing piece in the puzzle of how some coral reefs can recover from climate events, providing information that could help guide future conservation and restoration ...
Medical Xpress / Scientists find the gene that drives T-cell exhaustion, revealing new strategy to improve immune responses
Immunotherapy, which uses a patient's immune system to treat disease, has increased survival for some adults and children with cancer. However, it has had limited success against many pediatric solid tumors, in part because ...
Medical Xpress / Strength training causes fat cells to shrink even before weight loss, study suggests
Just seven days of strength training increased visceral fat burning in obese mice, even before any weight loss could be seen on a scale. In an experiment conducted at the State University of Campinas (UNICAMP), researchers ...
Phys.org / Coastal flooding occurs at predictable times, research reveals
Coastal flooding may seem unpredictable, a natural disaster that occurs randomly. But UCF researcher Ivan Haigh has found that recurrent coastal floods occur at highly predictable times.
Tech Xplore / US court sides with Pentagon in Anthropic AI ban
A U.S. appeals court on Friday upheld the Pentagon's decision to exclude Anthropic from its supply chain after the AI startup refused to remove certain safeguards on its Claude model.
