Our best models of cosmology suggest the universe will either go on forever, implode or rip itself apart. A new proposal suggests an even weirder destiny

A few millionths of a second after the Big Bang, the universe was so dense and hot that the quarks and gluons that make up protons, neutrons and other hadrons existed freely in what is known as the quark-gluon plasma. Th...

Researchers examined how artificial intelligence (AI) could affect drug development in the coming decade.

Swapping short car trips for walking or biking could achieve as much health gain as ongoing tobacco tax increases, according to a new study.

New federal rule could reduce out-of-pocket costs for key drugs and services for people with chronic conditions in high-deductible health plans with health savings accounts.

A new review article highlights the evolution and ecology of plant viruses. A team of biologists is now exploring many details of viral dynamics. They describe the subtle interplay between three components of the viral i...

Researchers have determined that a human gene present in 75% of the population is a key reason why a class of drugs for Alzheimer's disease seemed promising in animal studies only to fail in human studies.

Roughly 11% of high school seniors reported prescription drug misuse during the past year, and of those, 44% used multiple supply sources, according to a pair of recent studies.

CompCyst, a new test, distinguishes pancreatic cysts that are destined to become cancer and need to be surgically removed from cysts that can be left alone without causing harm. The researchers believe CompCyst has the c...

Leukemia stem cells protect themselves against the immune defense by suppressing a target molecule for killer cells. This protective mechanism can be tricked with drugs. Scientists now describe a new therapeutic approach...

A genetic mutation linked to dilated cardiomyopathy, a dangerous enlargement of the heart's main pumping chamber, activates a biological pathway normally turned off in healthy adult hearts, according to a new study.

Results suggest some forms of PD are an autoimmune disease triggered years before noticeable symptoms.

Scientists have discovered that a specific brain cell known as a 'projection neuron' has a central role to play in the brain changes seen in multiple sclerosis (MS). The research shows that projection neurons are damaged...

While revealing that metastatic breast cancer cells alter their shape to spread to other regions of the body, researchers develop a mathematical model that can be applied to study similar cellular systems.

Imagine powering your devices by walking. With new technology that possibility might not be far out of reach. An energy harvester is attached to the wearer's knee and can generate 1.6 microwatts of power while the wearer...

Neutron stars were recently in the news because the gravitational wave observatory, LIGO, detected a neutron star merger. Neutron stars are very interesting objects. A teaspoon of neutron star matter is so dense it would...

Radiation levels in parts of the Marshall Islands in the central Pacific Ocean, where the United States conducted nearly 70 nuclear tests during the Cold War, are still alarmingly high. Researchers tested soil samples on...

Multiple violations of injection safety and infection prevention practices -- from lack of handwashing to inappropriate re-use of medication vials -- were identified after an outbreak of septic arthritis at a New Jersey ...

Apathy is the most common neuropsychiatric symptom of dementia, with a bigger impact on function than memory loss -- yet it is under-researched and often forgotten in care.

Scientists have shown that small RNA molecules occurring naturally in cells, i.e. microRNAs, are also abundant in cell nuclei. Previously, microRNAs were mainly thought to be found in cytoplasm. The scientists also disco...

Oxidative stress could be a driving force in the spreading of aberrant proteins involved in Parkinson's disease.

Salt marshes are important habitats for fish and birds and protect coasts under sea level rise against stronger wave attacks. However, marshes themselves are much more vulnerable than previously thought. Stronger waves d...
