A team of researchers affiliated with several institutions in China created a photonic computer that was able to solve the subset sum problem. In their paper published in the journal Science Advances, the group describes...

One of the cornerstones of quantum theory is a fundamental limit to the precision with which we can know certain pairs of physical quantities, such as position and momentum. For quantum theoretical treatments, this uncer...

There’s been a lot of talk about quantum computers being able to solve far more complex problems than conventional supercomputers. The authors of a new paper say they’re on the path to showing an optical computer can...

A new study has devised a new type of chimeric antigen-receptor (CAR) T cell -- a family of promising immunotherapies for cancer -- that can be switched on and off on demand.

Engineering researchers have developed a device the size of a wristwatch that can monitor an individual's body chemistry to help improve athletic performance and identify potential health problems. The device can be used...

A plant-based diet may be key to lowering risk for heart disease. Researchers determined that diets with reduced sulfur amino acids -- which occur in protein-rich foods, such as meats, dairy, nuts and soy -- were associa...

The promise of flickering light to treat Alzheimer's takes another step forward in this new study, which reveals stark biochemical mechanisms: 40 Hertz stimulus triggers a marked release of signaling chemicals.

A new article puts an evolutionary twist on a classic question. Instead of asking why we get cancer, researchers use signaling theory to explore how our bodies have evolved to keep us from getting more cancer.

Chemists have discovered the structure of an influenza B protein called BM2, a finding that could help researchers design drugs that block the protein and help prevent the virus from spreading.

Researchers have described a previously unrecognized mechanism of bacterial transcriptional regulation that is obviously widespread in bacteria. In the future, their findings could also help fight antibiotic resistance.

Experiences early in life have an impact on the brain's biological and functional development, shows a new study by a team of neuroscientists.

By figuring out how a common virus hides from the immune system, scientists have identified a potential vaccine to prevent sometimes deadly respiratory infections in humans.

A large study links red and processed meat with higher risk of heart disease and death. Eating two servings of red meat, processed meat or poultry -- but not fish -- per week was linked to a 3 to 7 percent higher risk of...

When there are several processes going on at once, establishing cause-and-effect relationships is difficult. This scenario holds true for a class of high-temperature superconductors known as the cuprates. Discovered near...

Parents who speak to their infant in parentese, or baby-talk, help increase their child's language acquisition skills.

Most modern electronic devices rely on tiny, finely-tuned electrical currents to process and store information. These currents dictate how fast our computers run, how regularly our pacemakers tick and how securely our mo...

This rare finding was made by "accident," according to the research team that found the super-outburst.

Neuroimaging data sheds light on the brain networks used to produce speech. The findings could help in the development of new treatments for those with speech disorders.

A collaboration between McMaster and Harvard researchers has generated a new platform in which light beams communicate with one another through solid matter, establishing the foundation to explore a new form of computing...

Not only does exercise help burn those extra calories, but it can also have a protective effect against overeating, a new study reports.

Big data study combines information from a diverse set of experiements to identify patterns of brain activity common across people and tasks.

Cities are trying to cut levels of micrometre-scale particles in the air - but doing so leads to a rise in nanometre-scale particles that also damage health
