For The Better

Consumption of ultra-processed foods has increased over the past two decades across nearly all segments of the U.S. population, according to a new study.

Scientists have known for a century that female animals become more active just as they are about to ovulate, a behavior that evolved to enhance their chances of mating when they are fertile.

While gobies aren’t the only fish with camouflage abilities, new research shows that their colour change is influenced by their social context: they transform faster and better when alone. This is likely an adaptive, stress response to perceived threat…

A cell-based influenza vaccine has effectively provided protection against the flu in children and adolescents, according to a new study.

A new report finds more than 46,000 cancer cases annually in the United States could be prevented if Americans met the 5 hours per week of moderate-intensity recommended physical activity guidelines.

A new discovery about osteoporosis suggests a potential treatment target for that brittle-bone disease and for bone loss from rheumatoid arthritis.

Sunscreen that includes zinc oxide, a common ingredient, loses much of its effectiveness and becomes toxic after two hours of exposure to ultraviolet radiation, according to scientists.

Sustainable agriculture will not be achieved by one universal solution. A meta-analysis shows that the current focus on no-till farming does not achieve the desired results. A sustainable system of agriculture must be designed for local needs and in di…

An artificial intelligence (AI)-based technology rapidly diagnoses rare disorders in critically ill children with high accuracy. The benchmark finding foreshadows the next phase of medicine, where technology helps clinicians quickly determine the root …

The way a person’s brain responds to stress following a traumatic event, such as a car accident, may help to predict their long-term mental health outcomes, according to new research. The study followed more than 3,000 people for up to a year after exp…

A commonly available pesticide has been associated with an increased risk of chronic kidney disease (CKD).

The ability to detect and react to the smell of a potential threat is a precondition of our and other mammals’ survival. Using a novel technique, researchers have been able to study what happens in the brain when the central nervous system judges a sme…

Researchers have succeeded in creating a new type of super-stable, durable glass with potential applications ranging from medicines, advanced digital screens, and solar cell technology. The study shows how mixing multiple molecules — up to eight at a …

Medical researchers have shown that optimizing the energy metabolism of key cells enables people with HIV-1 to better defend themselves against the virus.

Researchers have improved understanding of the molecular mechanisms of a key protein that makes the stomach acidic. Their findings could lead to better drugs for stomach ulcers and shed light on the functions of similar proteins across the human body.
