Drunk mice sober up after a hormone shot

A hormone called FGF21 protects mice from ethanol-induced loss of balance and righting reflex by activating a specific part of the brain that controls alertness. The study reveals that higher FGF21 concentrations can dramatically accelerate recovery from intoxication.

Do you see me? New study examines how women of colour experience invisibility in the workplace

A recent landmark study found that women of color experience invisibility in traditionally white and male professions, with four distinct forms of invisibility identified. The study also reveals how different social power levels influence responses to invisibility, ranging from withdrawal to approach or pragmatic tactics.

How fruit flies feast for pleasure as well as necessity

Researchers discovered that fruit flies have distinct hunger drives, one driven by need and the other by pleasure, which arise from unique neural mechanisms. The study found that hungry flies increase feeding event duration and total events, and identified specific brain regions activated by pleasurable food environments.

How high altitude changes your body’s metabolism

Researchers at Gladstone Institutes discovered that chronically low oxygen levels, similar to those experienced at high elevation, rewire how mice burn sugars and fats. The study found lasting changes in metabolism, including lower blood glucose levels and body weight, which mirror what has been seen in humans who live at high altitude.

To help dry forests, fire needs to be just the right intensity, and happen more than once

Research suggests that wildfires need to fall within a narrow severity range to improve forest health. The study found that moderate severity fires are most effective at reducing community and ecosystem risk, but even these may not be enough to restore species composition. Land managers can use the predicted post-fire conditions to inf...

New “camera” with shutter speed of 1 trillionth of a second sees through dynamic disorder of atoms

Researchers at Columbia University have developed a new 'camera' that can see atomic structures in real-time, revealing the dynamic disorder of materials. This breakthrough enables better understanding of thermoelectric devices and waste heat conversion, leading to more efficient sustainable energy applications.

Transition to adulthood brings mental health declines for Black youth who interact with juvenile justice system, Mason researcher finds

A new study from George Mason University College of Public Health found that mental health symptoms worsened in Black youth who interacted with the juvenile justice system during transition to adulthood. Connectedness, particularly to family and community, was a protective factor against declining mental health.

Hair analysis shows child drug use could be twice as high as we think

A study of over 1,300 children aged 9-13 found a significant increase in substance use when combining hair analysis with survey results, nearly doubling the estimated number of child drug users. This suggests that hair analysis is a more accurate method for assessing adolescent substance abuse than self-reporting alone.

New study uncovers key culprit behind pediatric brain cancer metastasis

Researchers have identified a key cause of metastasis from aggressive brain cancer in children and found a potential new therapy. Medulloblastoma cells hijack neurodevelopmental signaling pathways to promote tumor cell spreading. Targeting these pathways with a drug called dasatinib has shown promise in killing metastatic tumors.
