The doctoral thesis of Sophia Hollick, Ph.D. '25, a recent graduate of Yale's Wright Lab in professor Reina Maruyama's group, has significantly contributed to answering a decades-long question in her field about whether or ...
Medical Xpress / How does mitochondrial DNA influence human health?
Some of your most important life partners are the mitochondria that power all your cells. You and these little cellular powerhouses are in a 1.5-billion-year-old evolutionary relationship—but mitochondria brought some baggage. ...
Phys.org / Artemis mission approaches lunar loop for first flyby since 1972
The Artemis astronauts entered the final phase of their run-up to a lunar loop on Monday, a tipping point of sorts that means the moon's gravity is now having a stronger pull on the spacecraft than Earth's.
Phys.org / Cell 'snowball' may be answer to large-scale tissue engineering
Cell cultures—single layers of cells grown in a small dish—have enabled researchers to study biological growth, develop or test drugs and even discover what causes some diseases. Cell spheroids, 3D versions of cell cultures ...
Phys.org / By age 7, most children quickly spot individuals' social biases toward social groups, study finds
Most elementary school-aged children have a surprising cognitive ability: they can detect—nearly as well as adults—when someone treats people from one social group differently than another. The study, "Children's and adults' ...
Phys.org / 'Switch' behind flash drought in Puerto Rico uncovered
In Puerto Rico, drought doesn't always arrive slowly. Sometimes, it appears in days. That speed can leave producers scrambling, reservoirs dropping, and communities facing water restrictions before they can react. In a place ...
Phys.org / Stitching precise patterns—with lasers
Just as embroiderers, with needle and thread, can transform plain fabric into an intricate pattern, engineers can use lasers and polymers to create flexible, complex structures that could transform life-saving sensing technology. ...
Medical Xpress / Diabetes drug metformin may echo the benefits of exercise in prostate cancer care
A new study has found that metformin, a widely prescribed diabetes drug, may mimic one of exercise's core biological effects in men with prostate cancer, raising levels of a molecule tied to energy balance and weight control ...
Medical Xpress / New therapeutic target identified for neuroendocrine tumors in the gastrointestinal tract
Neuroendocrine cells are unique in their ability to act both as nerve cells and hormone-making cells. They're scattered throughout the body, including the stomach, intestines, pancreas and lungs. Tumors that arise from these ...
Phys.org / Why cats stop eating—it's not just fullness
Why do cats often leave food unfinished? Many cat owners have experienced this puzzling behavior. Domestic cats are well known for eating multiple small meals throughout the day, a pattern thought to reflect their evolutionary ...
Medical Xpress / High‑fat diets linked to rapid decline in protective gut immune cells
In a preclinical study from Mass General Brigham, researchers have found that even short-term exposure to high levels of dietary fat results in a quick and selective loss of critical gut immune cells called ILC3s, promoting ...
Phys.org / Q&A: What drives the rise in red tides that threaten human health?
With its striking San Francisco Bay settings, director Alfred Hitchcock's iconic horror film "The Birds" has captivated audiences for more than 60 years. For Hitchcock, the film—set in an ocean-side town terrorized by swarming, ...
