Clinicians frequently order preoperative urinalyses for patients scheduled to undergo many common procedures. A new study finds that nearly nine out of 10 of preoperative urinalyses are unnecessary. Overuse of low-value ...

Internet-based cognitive behavioral therapy (CBT) for depression is often just as effective as traditional CBT. This is clear from an international study. However, some online treatments have components that can potentia...

Neural circuits within the retina are able to generate the information required to predict the movement and path of an object before visual signals leave the eye, researchers report.

A new system translates EEG data into a 3D movie which shows activity in all recorded regions of the brain. The heat map shows where seizures start and spread throughout the patient's brain, in addition to evaluating the...

Learning a new language can affect musical processing in children, researchers report. Findings support the theory that musical and linguistic functions are closely linked in the developing brain.

Exercise rewires the enhancers in DNA regions associated with the risk of disease development.

The infected chipmunks had no known contact with people.

People perceive pictures of individuals within photographs as less real and having "less mind", a new study reports.

Researchers have discovered that a cellular phenomenon called cryptic transcription, which had been previously described and linked to aging in yeasts and worms, is also involved in mammalian aging. They also discovered ...

For people with diabetes who are insulin dependent, glycemic control is a full-time job. But what if their medication could do the work for them -- an insulin whose activity in the bloodstream responds to the blood gluco...

When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. Researchers observed su...

A new treatment for advanced urothelial cancer was effective with tolerable side effects in an international, multi-center phase 2 clinical trial. The trial results prompted a U.S. Food and Drug Administration (FDA) acce...

EEG study reveals when we imagine a song, similar brain activity occurs as when we experience moments of silence in music.

In the latest of ongoing efforts to expand technologies for modifying genes and their expression, researchers have developed chemically modified guide RNAs for a CRISPR system that targets RNA instead of DNA. These chemi...

Researchers have now developed a non-invasive method to help diagnose celiac disease and which uses saliva. This research has shown that it is possible to considerably reduce the number of endoscopies, which are currentl...

Researchers have discovered a new method of X-ray imaging based on the coloring abilities of the natural mineral hackmanite. The international group of researchers also found out how and why hackmanite changes color upon...

New research demonstrates a metabolic regulatory molecule called Them1 prevents fat burning in cells by blocking access to their fuel source. The study may contribute to the development of a new type of obesity treatment...

Among older adults with obesity, combining aerobic exercise with moderate reductions in total daily calories led to greater improvements in vascular health compared to exercise alone. Reducing calorie intake by approxima...

One type of the salmonella bacteria is much more likely to cause disease and fend off frontline antibiotics when acquired in Europe, Asia, and parts of Africa rather than domestically in the United States.

One estimate suggests that 13 billion tons (12 metric tons) of ice made its way into the ocean on a single day.

Marine protected areas in the English channel are still at risk from fishing activities, finds Adam Vaughan as he visits one on board a Greenpeace vessel
