Bizarre forms of matter called time crystals were supposed to be physically impossible. Now they’re not --

Metamaterials don't exist in nature, but their ability to make ultra-thin lenses and ultra-efficient cell phone antennas, bend light to keep satellites cooler and let photovoltaics absorb more energy mean they offer a wo...

In order to be an astronaut you need a strong stomach, one that won't make you puke if you see a turd floating by or when you need to poop into a bag taped to your rear end.

The NASA Transition and Authorization Act instructs the space agency to send humans to Mars, robots to Europa and look for life - but not to study Earth

University of Minnesota electrical and computer engineering researchers have created a magnetic tunnel junction that can be switched by a pulse of light lasting one trillionth of a second--a new record. The magnetic tunn...

A new gene that can lead to sudden death among young people and athletes has now been identified by an international team of researchers. The gene, called CDH2, causes arrhythmogenic right ventricle cardiomyopathy (ARVC)...

A new study could change scientists' understanding of how the brain works -- and could lead to new approaches for treating neurological disorders and for developing computers that 'think' more like humans.

While many anti-aging drugs don't live up to their claim, a tightly replicated study has discovered that a chemical used to detect amyloid plaques found in the brains of those with Alzheimer's extended the lifespan of th...

A new intervention to tamper with parasites' communication system may lead to the development of drugs to treat, and prevent the spread of, devastating diseases such as African sleeping sickness, leishmaniasis and Chagas...

Eating a diet lacking in healthy foods and/or high in unhealthy foods was estimated to contribute to more than 400,000 deaths from heart and blood vessel diseases in the United States in 2015. Eating more nuts, vegetable...

Using marijuana raises the risk of stroke and heart failure even after accounting for demographic factors, other health conditions and lifestyle risk factors such as smoking and alcohol use, according to new research.

Researchers have learned how dopamine governs ongoing decisions, yielding insights into Parkinson's, drug addiction.

Researchers have identified an immune pathway that promotes the formation of a cell that can develop into new tissues and organs.

The medical community needs a better understanding of the biology of pain and how it plays out in individuals to be able to combat the national epidemic of addiction to painkillers. This is especially urgent given no ana...

Neuroscientists have found that healthy neurons receive messages from injured neighbors that can lead to death. If they can block these messages from getting through, they may be able to slow the progress of neurodegener...

Scientists study the germline of the roundworm Caenorhabditis elegans to identify the mechanisms that control stem cell proliferation and homeostasis, as well as to advance our molecular understanding of homologous signa...

Among women of childbearing age in the US, fish consumption has increased in recent years while blood mercury concentrations have decreased, suggesting improved health for women and their babies, a new study shows.

Two new drug candidates have now been designed to target prostate and triple negative breast cancers. The new research demonstrates that a new class of drugs called small molecule RNA inhibitors can successfully target a...

Some chemicals added to furniture, electronics and numerous other goods to prevent fires may have unintended developmental consequences for young children, according to a pilot study.

Common impotence drugs such as Viagra may have a life-prolonging effect on patients who have suffered a myocardial infarction, a new study suggests. The finding calls for the need of prospective studies of impotence drug...

Like a busy interchange, the surface of every living cell hums with activity. Proteins and lipids are constantly in motion, detecting, processing, and responding to signals from the outside world. They interact and move ...

The field of metamaterials, an intersection of materials science, physics, nanotechnology and electrical engineering, aims to produce structures with unusual electromagnetic properties. Through the careful combination of...
