Scientists at the University of Sussex have disproved the existence of a specific type of axion - an important candidate 'dark matter' particle - across a wide range of its possible masses.

For the first time, engineers at Caltech have created a stable ring of plasma in open air--essentially capturing lightning in a bottle, but without the bottle.

Quantum computing could solve problems impossible for today's supercomputers. The challenge for this new form of computing is processing the quantum bits (qubits) that represent data. A qubit can be made by controlling t...

A new device, proven safe and effective, has been developed to treat diastolic heart failure.

The unparalleled liquid strength of cartilage, which is about 80 percent water, withstands some of the toughest forces on our bodies. Synthetic materials couldn't match it -- until "Kevlartilage" was developed.

A lot of people seem willing to spend hundreds to find out whether they're aging faster or slower than their chronological age would suggest. Unfortunately, they're just going to have to wait and see. A head-to-head comp...

The bacterium Pseudomonas aeruginosa is the leading cause of hospital-acquired infections. The pathogen is resistant to many antibiotics so treating those infections, particularly in patients with compromised immune syst...

Rendez-vous IN 2029 the inhabitants, if any, of the planet GJ 273b will receive a message that will change their lives forever. Encoded in radio signals emanating from an innocuous-looking blue-green planet 12.4 light-ye...

The first genetic mutation that appears to protect against multiple aspects of biological aging in humans has been discovered in an extended family of Old Order Amish living in the vicinity of Berne, Indiana, report scie...

Researchers have singled out a bacterial enzyme behind an imbalance in the gut microbiome linked to Crohn's disease. The new study suggests that wiping out a significant portion of the bacteria in the gut microbiome, and...

Type 1 diabetes has been successfully reveresed in a mouse model by infusing blood stem cells pre-treated to produce more of a protein called PD-L1, which is deficient in mice (and people) with type 1 diabetes. The cells...

The leverlike guitar accessory known as a whammy bar is best used to bend and distort a single note--think Jimi Hendrix's famous rendition of the Star Spangled Banner from Woodstock 1969. But it doesn't sound very nice i...

Researchers are investigating a way to temporarily loosen the blood-brain barrier to deliver drugs with the assistance of microbubbles. In a new advancement, they have developed a system in preclinical models that offers...

Discontinuity of care puts older patients at higher risk of emergency hospitalization.

By focusing on genetic variations within a primary tumor, differences between the primary and a metastatic tumor, and additional diversity from tumor DNA in the blood stream, physicians can make better treatment choices ...

Researchers have published a functional and structural compendium of the simultaneous changes taking place in the heart, spleen and kidneys in mice during the period of acute heart failure immediately following a heart a...

Until now, sequencing-based gut microbiota research has been describing such dysbiotic states in terms of proportional shifts in microbiome composition. However, when it comes to the bacterial content of your bowels and ...

Advanced clinical trials are underway for at least 10 investigational therapies that have shown promise in slowing or blocking development of Alzheimer's disease, creating hope that a preventive strategy may be in reach....

As health delivery moves away from disease-based models to person centered delivery, a new study addresses the development of a new practical tool to support organizations and practitioners in delivering this new approac...

Microbes living in your gut can help protect against the effects of a high-salt diet, according to a new study.

The ability to form long-term social memories is essential for remembering faces and developing social bonds. Scientists have now discovered that the tiny CA2 region in the hippocampus is involved in the linking up of me...

Fortified and biofortified foods are at the forefront of efforts to combat vitamin A deficiency worldwide. But little is known about what influence processing may have on the retention of vitamin A precursors in these fo...
