Phys.org / Advanced optical imaging reveals hidden activity in blood immune cells
A routine blood sample contains a diverse collection of immune cells that can reveal important clues about health and disease. These cells, known as peripheral blood mononuclear cells (PBMCs), are widely used to study infections, ...
Medical Xpress / Cerebroid study hints at how maternal inflammation may influence fetal brain development
Past studies suggest that a mother-to-be's heightened immune responses during pregnancy are linked to a higher risk of conditions affecting their offspring's brain development. While this association is well documented, the ...
Phys.org / Not a cheetah: Ancient DNA reveals the surprising Arctic life of extinct North American cat
A new study led by researchers at the University of California, Santa Cruz, has overturned decades of assumptions about Miracinonyx trumani, the extinct predator popularly known as the American cheetah. By analyzing nuclear ...
Phys.org / AI helps reveal the immersive sensory experiences of ancient Etruscan tombs
The Etruscan painted tombs in Tarquinia, Italy, date to the first millennium BCE and are known for their vivid scenes of music, feasting, processions and the afterlife. While these tombs have been extensively studied, archaeologists ...
Medical Xpress / Brain signaling mechanism may explain clozapine weight gain
Researchers at UT Southwestern Medical Center have identified a key brain signaling pathway that appears to drive the substantial weight gain often associated with clozapine, a widely used antipsychotic medication. The preclinical ...
Phys.org / Iron Age Botswana site sourced copper across southern Africa—but tin from just one place
Around 700 years ago, people living on hilltop settlements on the edge of the Kalahari wore beads, bangles and clips made from metal traded across the southern half of the African continent.
Medical Xpress / Focal therapy use remains uncommon in nonmetastatic prostate cancer
For patients with nonmetastatic prostate cancer, focal therapy use has remained uncommon across risk groups, and its use was defined as inappropriate in about half of recipients, according to a research letter published online ...
Phys.org / Breaking through AlphaFold's limits to predict how proteins change shape
Conformational changes in proteins are vital to their function yet remain challenging for state-of-the-art artificial intelligence, such as AlphaFold3, to predict. Researchers at the Institute for Molecular Science (IMS), ...
Medical Xpress / Local neural wiring may set the brain's range of activity patterns
The human brain contains billions of neurons, specialized nerve cells that receive, transmit and process information through electrical and chemical signals. Human thoughts, sensory perceptions and behaviors are known to ...
Medical Xpress / Diabetes drug metformin could be repurposed to help slow aging mechanisms
Metformin, a widely prescribed, safe and inexpensive drug for type 2 diabetes, is a first-line treatment that lowers blood sugar and improves the body's response to insulin. The drug appears to trick cells into sensing an ...
Phys.org / Students with lower grades earn degrees more often when they belong to an academic major's majority group
Despite efforts to encourage broader participation, women earn about 25% of undergraduate engineering degrees and 18% of undergraduate computer science degrees—and men remain a small minority among people earning nursing ...
Medical Xpress / End of free school meal program led to increased stress and hunger, poorer diets and reduced focus, say teachers
How did students' diets and behavior change after the expiration of a pandemic-era universal free school meal program in 2022? Researchers asked teachers for their observations of the impact on students and found that teachers ...
