A new type of HIV drug currently being tested works in an unusual way, scientists have found. They also discovered that when the virus became resistant to early versions of these drugs, it did not do so by blocking or pr...

Researchers and physicians have grappled with the role of 'adjuvant,' or post-surgery, chemotherapy for patients with early-stage colon cancer, even for cancers considered high risk. Now researchers have found an associa...

A modification called phosphorylation made to a protein called RUNX3 may promote cancer progression by allowing cell division, scientists have discovered. The phosphorylation, or the addition of a phosphate group to a mo...

Aging, neurodegenerative disorders and metabolic disease are all linked to mitochondria, structures within our cells that generate chemical energy and maintain their own DNA. In a fundamental discovery with far-reaching ...

Today some of the world's experts on antibiotic resistance called on the UN to act to reduce the growing number of deaths due to limited access to effective antibiotics.

A new technique could make tissue regeneration cheaper and safer for health-care systems and their patients. The study has identified new ways in which proteins and various biological molecules -- known as growth factors...

A key 'twist' in a Rubik's cube-like plant puzzle has been discovered by scientists. This find could pave the way to new, or more effective pharmaceuticals, they say.

Though health care is not without risks or error, hospital employees can support a culture of patient safety by identifying, reporting, and learning from medical mistakes that have or could have harmed patients. In a new...

A new patient study could open a new opportunity to rehabilitate patients with spinal cord damage, say investigators. This study represents the first time that attempts were made to rehabilitate patients paralysed as a r...

Recently discovered potent antibodies can be used to generate a specific type of cell called chimeric antigen receptors, or CARs, that can be used to kill cells infected with HIV-1, new research suggests.

Scientists have captured new images of a calcium-shuttling molecule that has been linked to aggressive cancers. The three-dimensional structure could help researchers develop novel therapies and diagnostic tools for dise...

Researchers have found evidence that bone marrow transplantation may one day be beneficial to a subset of amyotrophic lateral sclerosis.The data suggests the most common genetic mutation associated with ALS plays an impo...

A single brain receptor is responsible for a range of symptoms in mice that are reminiscent of obsessive-compulsive disorder, according to a new study. The findings suggest that OCD and other psychiatric disorders could ...

Everybody knows the force that is required to activate a light switch on a wall - a finger is enough. But how much force do you need to apply if the device was dramatically reduced to the "nanoscale world", that is, how ...

It has a funny name -- coxsackievirus -- but there's nothing funny about how this tiny germ and its close relatives sicken their hosts. Researchers have designed a genetic modification to one type of coxsackievirus that ...

Would having your exercise performance compared to that of your peers motivate you do more? A new study suggests that it might. And adding a financial incentive would only sweeten the deal even more. Comparing performanc...
