Physicists have learned how they could breed Schrödinger cats in optics. Scientists tested a method that could potentially amplify superpositions of classical states of light beyond microscopic limits and help determine...

The measured mass of electrons in solids is always larger than the value predicted by theory. The reason for this is that theoretical calculations do not account properly for various interactions with other electrons or ...

While current guidelines indicate that cervical cancer screening can be stopped for average risk patients after age 65, many women lack the appropriate amount of screening history to accurately assess their risk. A new s...

Imagine wearing clothes with layers of paper that protect you from dangerous bacteria. A research team has invented an inexpensive, effective way to kill bacteria and sanitize surfaces with devices made of paper.

Using a mouse heart attack model, researchers have shown that knocking out one particular lipid-modifying enzyme, along with a short-term dietary excess of a certain lipid, can improve post-heart attack healing and clear...

The most popular varieties of tea -- including black tea, green tea, Oolong tea, white tea, and chai -- all come from the leaves of the evergreen shrub Camellia sinensis, otherwise known as the tea tree. Despite tea's cu...

Cardiovascular risk factors such as high blood pressure, cholesterol and smoking have long been associated with cognitive deficiencies in adults. A new study found the burden of cardiovascular risk factors from childhood...

Ontario's stroke prevention strategy appears to have had an unexpected, beneficial side effect: a reduction also in the incidence of dementia among older seniors. A new paper is the first to look at the demographics of b...

The detection of gravitational waves topped nearly every chart highlighting the most important science stories of 2016. LIGO, the Laser Interferometer Gravitational-Wave Observatory, made headlines by detecting direct ev...

The use of low-dose aspirin (81 mg) reduces the risk of breast cancer in women, a new study concludes. Researchers saw an overall 16 percent lower risk of breast cancer in women who reported using low-dose aspirin at lea...

A new type of cancer-fighting nanoparticle has been created by researchers, aimed at shrinking breast cancer tumors, while also preventing recurrence of the disease.

Simply adjusting the dose of an older adult's psychiatric medication could reduce their risk of falling, a new study suggests.

Finding new drugs that can more effectively kill cancer cells or disrupt the growth of tumors is one way to improve survival rates for ailing patients. Researchers are using supercomputers to find new chemotherapy drugs ...

Studies have suggested a link between fitness and memory, but researchers have struggled to find the mechanism that links them. A new study found that the key may lie in the microstructure of the hippocampus, a region in...

A new mechanism produces a water-resistant chemiluminescent probe that is 3,000-times-brighter than those currently in use. It has particular application to medical and cancer diagnosis.

This research highlights biological mechanisms driven by insulin resistance that impair blood vessel health and may be shared by both cancer and cardiovascular disease.

The human-machine mind meld is just around the corner if you believe the buzz coming out of Silicon Valley these days. But neuroethicists worry the technology poses a threat to the last bastion of privacy, our innermost ...

A SpaceX Falcon rocket lifted off from the Kennedy Space Center in Florida on Monday (May 1) to boost a classified spy satellite into orbit for the U.S. military, then turned around and touched down at a nearby landing p...

Breast cancers detected by mammography screening do not spontaneously disappear or regress if left untreated, according to a new study. The scientific findings contradict claims that many cancers found via mammography ma...

The risk of heart transplant rejection can be reduced by desensitising patient antibodies, according to new research.

Investigators have identified silent, seizure-like activity in the hippocampus -- a brain structure significantly affected in Alzheimer's disease -- in two patients with Alzheimer's disease and no known history of seizur...

Alternate day fasting regimens have increased in popularity because some patients find it difficult to adhere to a conventional weight-loss diet. A new article reports on a randomized clinical trial that compared the eff...
