Structure of supercritical water decoded

Scientists at Ruhr University Bochum have shed light on the structure of supercritical water, finding that water molecules form few hydrogen bonds in this state. The research reveals that water behaves like a gas, with short-lived molecular interactions between hydrogen and oxygen atoms.

How big brains and flexible skulls led to the evolution of modern birds

Research from the University of Chicago and University of Missouri reveals how modern birds' larger brains led to changes in their skulls, jaw muscles, and feeding mechanics. This evolution allowed for the development of cranial kinesis, enabling birds to move different parts of their skull independently.

‘It still hurts, she said’: why pain medication may not be as effective for women as it is for men

Researchers found that female rodents experience heightened pain sensitivity due to activation of Panx1 channels releasing leptin, a hormone associated with increased pain sensitivity. This study aims to personalize treatment for patients and may explain the over-representation of women experiencing chronic pain compared to men.

Webb telescope captures its first direct images of carbon dioxide outside solar system

The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system. The observations suggest that four giant planets formed like Jupiter and Saturn by slowly building solid cores, providing strong evidence for core accretion as their formation model.

Surgery in kids with mild sleep-disordered breathing tied to fewer doctor visits, meds

A recent NIH-supported clinical trial found that adenotonsillectomy significantly reduces medical office visits and prescription medicine use in children with mild sleep-disordered breathing. The surgery was tied to a 32% reduction in health care encounters and a 48% reduction in prescriptions used among participants.

From order to chaos: Understanding the principles behind collective motion in bacteria

Researchers discovered how bacterial swarms transition from organized movement to chaotic flow as confinement radius increases. The study reveals intermediate states between order and turbulence through large-scale experiments, computer modeling, and mathematical analysis. These findings provide insights into the universal properties o...

Aston University study reveals the illusion of ‘dazzle’ paint on World War I battleships

A new analysis of 105-year-old data found that while dazzle camouflage had some effect, the 'horizon effect' had a much greater influence on confusing enemy ships. The study, led by Aston University researchers, showed that when people looked at a ship in the distance, they significantly underestimated its direction of travel.

New AI model analyzes full night of sleep with high accuracy in largest study of its kind

A powerful AI tool, PFTSleep, has been developed to process an entire night's sleep with high accuracy. The model, built on transformer architecture, analyzes brain waves, muscle activity, heart rate, and breathing patterns to classify sleep stages more effectively than traditional methods.

Early surgical intervention in children with sleep-disordered breathing reduces need for doctor visits, prescriptions

A randomized trial found that adenotonsillectomy surgery reduced healthcare utilization in children with mild sleep-disordered breathing by 32% fewer doctor visits and 48% fewer prescriptions. This effective early intervention supports reducing behavioral, neurocognitive, cardiovascular, and cardiometabolic issues.

Dr. Theodore Scott Nowicki awarded $4.5M NCI grant to advance next generation of cellular immunotherapies for solid tumors

Dr. Nowicki's team has engineered 'supercharged' T cells that produce extra TNF-alpha to boost cancer-fighting ability, offering a potentially more precise and toxic-free treatment option. The new funding will help test these enhanced T cells in preclinical models to evaluate their effectiveness.

Impaired gastric myoelectrical rhythms associated with altered autonomic functions in patients with severe ischemic stroke

Patients with severe ischemic stroke show impaired gastric motility and autonomic dysfunction, with reduced normal gastric slow waves and increased sympathetic activity. These findings suggest a link between gastric myoelectrical rhythms and autonomic function in ischemic stroke.

Pro-life people partly motivated to prevent casual sex, study finds

A study found that pro-life people are partly motivated to prevent casual sex, contradicting the common assumption that sanctity-of-life concerns drive their views. The researchers suggest that pro-life positions are also influenced by a desire to discourage loose sexual norms and promote social values.

Neighborhood dispute among cells: Whichever successfully exerts force wins

Researchers discovered a previously unknown mechanism in mechanical cell competition, where stronger "winner" cells exert more mechanical forces to outcompete weaker "loser" cells. The finding challenges classical interpretation of cell competition and suggests that active resistance to elimination is the key factor in survival.
