Researchers have used cryo-electron microscopy to elucidate for the first time the structure and function of a very small enzyme embedded in cell membranes. This enzyme builds complex sugar trees that are subsequently at...

Combining neuroimaging data with machine learning technology, researchers discover children with well-connected brain hubs have either very specific cognitive problems, such as poor listening skills, or no cognitive diff...

Scientists have identified a rare, new cell in the immune system with 'Jekyll and Hyde properties.' These cells play a key protective role in immunity to infection but -- if unregulated -- also mediate tissue damage in a...

With the covid-19 virus spreading in a growing number of countries, many of us are wondering if and how we should prepare. Here's what to do

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo report the first occurrence of directly splitting one photon into three.

For the first time, researchers have used an advanced analytical technique known as dual-comb spectroscopy to rapidly acquire extremely detailed hyperspectral images. By acquiring a full spectrum of information for each ...

Human fingers are sculpted from a primitive pad-like structure during embryonic development. Sometimes, this process goes awry and babies are born with fused fingers or toes. A new study reveals new factors involved in t...

A research team has found that brains treated with certain drugs within a few days of an injury have a dramatically reduced risk of developing epilepsy later in life. The development of epilepsy is a major clinical compl...

Children and teens with epilepsy who were treated with pharmaceutical cannabidiol (CBD) had much better seizure control than those who were treated with artisanal CBD, according to a preliminary study.

If you want to reduce levels of inflammation throughout your body, delay the onset of age-related diseases, and live longer -- eat less food. That's the conclusion of a new study that provides the most detailed report to...

Liberia was the epicenter of a high-profile Ebola outbreak in 2014-15, which led to more than 10,000 deaths in West Africa. But for all the devastation the illness caused, it could have been worse without an innovative, ...

Researchers who have discovered why the drug remdesivir is effective in treating the coronaviruses that cause Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS) expect it might also be e...

According a new study, the microscopic toner nanoparticles that waft from laser printers may change our genetic and metabolic profiles in ways that make disease more likely.

Cancer mutations can be caused by common gut bacteria. By exposing human mini-guts to a particular strain of Escherichia coli, scientist uncovered that these bacteria induce a unique mutational pattern in human DNA. This...

Scientists describe a new method for detecting point mutations. The technique can be applied in living cells, offering a rapid, highly accurate and inexpensive means of identifying mutations relevant to human health.

Our skin protects us from physical injury, radiation and microbes, and at the same time produces hair and facilitates perspiration. Details of how skin cells manage such disparate tasks have so far remained elusive. Now,...

An international team of researchers identifies a compound that corrects genetic abnormalities involved in the onset and progression of Huntington's disease for which there is no definitive treatment. They successfully r...

The same way baking soda breaks down grease and grime, making surfaces easier to clean, researchers now show that a new therapeutic molecule can break apart communities of harmful bacteria, opening the way for bacteria-k...

A study reports that the long-term stability of treatment gains for children and adolescents diagnosed with obsessive-compulsive disorder (OCD), participating in a stepwise manualized treatment, is excellent.

Compounds containing metals could hold the key to the next generation of antibiotics to combat the growing threat of global antibiotic resistance. Researchers, working with a network of international collaborators, have ...

Increased heat stress as a result of global warming will have a detrimental effect on health and productivity, researchers warn. One major concern is the impact climate change will have on the health of multiple sclerosi...

As the brain starts to develop new habits, activity in the dorsolateral striatum increases. As the activity bursts increase, the habit becomes stronger. Inhibiting neural activity with optogenetics reduces habit behavior...
