There is remarkable biodiversity in all but the most extreme ecosystems on Earth. When many species are competing for the same finite resource, a theory called competitive exclusion suggests one species will outperform t...

The fascinating array of genetic changes that confer pesticide resistance in Anopheles mosquitoes has been reviewed. Findings highlight the interplay between human interventions, mosquito evolution, and disease outcomes,...

Attention-deficit/hyperactivity disorder (ADHD) increases the risk of subsequent sexually transmitted infections (STIs) among adolescent and young adult populations by about three times, reports a new study.

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don't work...

A study to be published in eNeuro reports scheduled feeding times improved motor activity, sleep quality and quality of life in mouse models of Huntington's disease.

Working with a simple mathematical model in which chance plays a key role, researchers calculated how long it would take a bacterial infection or cancer cell to take over a network of healthy cells. The distribution of i...

In addition to reducing headache frequency and severity, surgical treatment for migraine leads to significant improvements in everyday functioning and coping ability, according to a new study.

In a surprising finding, blacks and whites have the same risk of developing diabetes when all biological factors for the disease are considered over time, reports a study. The finding flips long-held beliefs that there i...

According to researchers, the ability of a male rat's brain to store memory changes depending on whether the environment in which they acquire information is safe or dangerous.

A new neuroimaging study reveals pericytes, a type of cell found in the brain's blood vessels, grow to compensate for the loss of neighboring cells.

Physics could soon make it possible to replace those bulky, heavy, glass lenses on the front of cameras with wafer-thin "metalenses."

A new study pinpoints the inverse correlation between a known oncogene -- a gene that promotes the development of cancer -- and the expression of an oncosuppressor microRNA as the reason for extended pancreatic cancer su...

Recently, researchers have been studying diseases with a new approach: small, organ-on-a-chip devices that mimic the functions of human organs, serving as potentially cheaper and more effective tools. Now researchers hav...

Despite improvement in the rates of people dying of sepsis in the hospital, the condition is still a leading cause of hospital readmissions and costs, as well as long-term disabilities and impairments, prompting medical ...

In just four months, high-doses of vitamin D reduce arterial stiffness in young, overweight/obese, vitamin-deficient, but otherwise still healthy African-Americans, researchers say.

Researchers have discovered a new biomarker that can help diagnose Huntington's disease. They note the findings could result in the development of treatments to postpone neuron death in those who carry the Huntington's g...

Few will deny 2017 was a rough year. But believe it or not, we're still living in the best time ever to be alive, and the world as a whole is better off than it has been at any other time in human history. People are liv...
