A particle traveling from one spot to another doesn't exactly stay a particle, or at least not the same kind of particle.

Researchers have identified a previously unknon role of a cellular signaling molecule involved in release of the 'hunger hormone' ghrelin, a finding that could have implications for optimal treatment of children taking b...

Similarly to cars, cells need a steering mechanism that guides them towards a certain target or direction. Scientists have discovered the function of a key protein involved in cells' movement and clarified how cells migr...

Where light and matter intersect, the world illuminates. Where light and matter interact so strongly that they become one, they illuminate a world of new physics, according to Rice University scientists.

Runaway electrons, a searing, laser-like beam of electric current released by plasma disruptions, could damage the interior walls of future tokamaks the size of ITER, the international fusion experiment under constructio...

Most of us think of diffusion in the context of its scientific definition as the process whereby particles of liquids, gases or solids intermingle and in dissolved substances move from a region of higher to one of lower ...

Researchers have identified a brain mechanism that could be a drug target to help prevent tolerance and addiction to opioid pain medication, such as morphine.

Researchers have found that omega-3 fatty acids reduced brain damage in a neonatal mouse model of stroke.

In a landmark discovery, researchers have unraveled the metastatic mechanism of melanoma, the most aggressive of all skin cancers. Their work may lead to a cure for the deadly disease.

As cells move throughout our bodies, they often have to squeeze through tight nooks and crannies in their environment, reliably springing back to their original shape. The structures involved in this process are still a ...

As faculty chair for Medicine and Neuroscience at Singularity University and curator of our annual Exponential Medicine conference (apply to join us this Oct 8-11th), I cross paths with many technologies which have poten...

People who remained sedentary after mentally demanding tasks consumed more calories than those who exercised, a new study has concluded.

Researchers have protected nonhuman primates against Ebola Sudan four days following exposure to the virus.

A study of more than 13,000 people has found that even after accounting for such risk factors as high blood pressure, high cholesterol and diabetes, so-called morbid obesity appears to stand alone as a standout risk for ...

The first global-scale genetic study of Salmonella Enteritidis bacteria, which is a major cause of blood poisoning and death in Africa and food poisoning in the Western World, has discovered that there are in fact three ...

Scientists have shown that unexpectedly, esophageal cancer cells do not divide faster than their normal neighbors. But unlike normal cells, the tumor cells produce slightly more dividing daughter cells than non-dividing ...

Researchers use new experimental models and analytical tools to investigate genes regulated by Foxn1, becoming the first to identify the DNA sequence bound by the transcription factor. Among the hundreds of genes whose e...

Is the occurrence of a fragility fracture -- where Medicare beneficiaries broke a hip, wrist or shoulder -- a missed opportunity to reduce exposure to prescription drugs associated with fracture risk?

In doses equivalent to those used regularly in human children, antibiotics changed the mix of gut microbes in young mice to dramatically increase their risk for type 1 diabetes.

Permanent brain damage from a stroke may be reversible thanks to a developing therapeutic technique, a study has found. The novel approach combines transplanted human stem cells with a special protein that the US Food an...

New research demonstrates how two key proteins mediate the organization of chromosomes and our genome, shedding light on one of the key genetic processes for every person. With this key basic information in hand, scienti...

In a tiny quantum prison, electrons behave quite differently as compared to their counterparts in free space. They can only occupy discrete energy levels, much like the electrons in an atom - for this reason, such electr...
