For The Better

New research supports the hypothesis that Alzheimer’s disease is caused by a decline in levels of a protein called amyloid-beta.

The researchers’ unique platform solves a key problem in water harvesting: Collected water droplets form a thermal barrier that prevents further condensation, so they need to be removed from the surface as rapidly as possible to make room for more harv…

The evolutionary pros and cons of group living vary for males and females, according to a study of ostriches.

A new technique enables on-device training of machine-learning models on edge devices like microcontrollers, which have very limited memory. This could allow edge devices to continually learn from new data, eliminating data privacy issues, while enabli…

Researchers describe how different types of repetitive DNA elements are controlled by the same silencing mechanism in fruit fly ovaries. Central to their findings is an uncharacterized protein that the researchers named ‘Kipferl’, which ensures the eff…

A new system of algorithms enables four-legged robots to walk and run on challenging terrain while avoiding both static and moving obstacles. The work brings researchers a step closer to building robots that can perform search and rescue missions or co…

Enrollment has begun in an early-stage clinical trial evaluating bacteriophage therapy in adults with cystic fibrosis (CF) who carry Pseudomonas aeruginosa (P. aeruginosa) in their lungs. The trial is evaluating whether the bacteriophage, or ‘phage,’ t…

Researchers have identified a pathway in the brains of mice that is activated when the animals see other mice scratching and that, surprisingly, does not involve the brain’s visual cortex.

Planetary scientists identified a potential source of a special kind of meteorite. Its characteristics could explain certain discrepancies in how near-Earth asteroids are classified.

The microscopic creatures like geckos and octopuses fabricated by 3D laser printing could open up new opportunities in fields such as microrobotics or biomedicine. These ‘life-like’ 3D microstructures are made from novel smart polymers whose size and m…

Acetaminophen use during pregnancy is associated with sleep and behavior problems consistent with attention deficit hyperactivity disorder (ADHD), according to a new study.

A milestone report proposes a new technique for modeling molecular life with computers. The advance promises new insights into the fundamental biology of a cell, as well as faster and more precise treatment of human disease.

Scientists conducted a clinical trial and found that time-restricted eating improved measures of health and wellbeing in firefighters. The lifestyle intervention only required the firefighters to eat during a 10-hour window and did not involve skipping…

Both time-restricted eating (TRE) and high-intensity interval training (HIIT) have been shown to improve cardiometabolic health in people who are overweight and at risk of serious disease. Now a randomized, controlled trial has tested whether combining…

Evidence in mice and human brain tissue reveals a mechanism that may explain the sex-based differences in Alzheimer’s disease, including why females are more vulnerable. Researchers report that female brains show higher expression of an X-linked enzyme…

Researchers mapped out many of the cells, genes, and cellular pathways that are modified by exercise or a high-fat diet. They hope their findings will help guide the design of drugs that might mimic some beneficial effects of exercise.

Obesity afflicts approximately 42 percent of the U.S. adult population and contributes to the onset of chronic diseases, including diabetes, cancer, and other conditions. While popular healthy diet mantras advise against midnight snacking, few studies …
