Exotic new states of matter contain patterns that repeat like clockwork --

A new article compares cancer detection rates (CDR) for screening digital breast tomosynthesis (DBT) versus full-field digital mammography (FFDM). Researchers found that DBT results in 'significantly increased CDR' -- ir...

Researchers discovered that the human diet -- a result of increased meat consumption, cooking and agriculture -- has led to stark differences in the saliva of humans compared to that of other primates.

Underwater and airborne cameras recently captured an astounding sight: feeding whales producing bubble nets to trap their prey.

A study has now found that a type of opsin known as neuropsin is expressed in the hair follicles of mice and synchronize the skin's circadian clock to the light-dark cycle, independent of the eyes or brain. Researchers n...

New research signposts a new, less invasive approach to identify killer T lymphocytes in patients with gastrointestinal tumors with low mutational burden who are refractory to approved immune-based treatments.

For the rising number of cancer survivors worldwide, there's growing evidence that exercise is an important part of recovery. But how much, and what type of exercise, is needed?

Researchers discover that the activity of the nervous system might influence human longevity. Neural excitation linked to shorter life, while suppression of overactivity appears to extend life span. Protein REST, previou...

Mutations in the gene that encodes a protein called ANT cause a variety of conditions, such as heart disease, but the underlying mechanism of how these mutations trigger disease has been unclear. Researchers discovered t...

Researchers have discovered a circuit in rats that links cigarette smoking and the risk of developing type 2 diabetes, according to a new study.

Researchers clarify mechanisms that allow hard-to-treat cancers to develop, and have identified strategies that could lead to new therapies.

A study describes a new rapid assay for Lyme disease that could lead to a practical test for use by healthcare providers. The researchers found the assay, which uses several biomarkers to detect Lyme disease infection, w...

A new study of tumor samples from people with the rare genetic syndrome neurofibromatosis type 1 (NF1) has uncovered novel molecular clues about which tumors are most likely to be aggressive in those with NF1. According ...

Insulin is normally produced by pancreatic beta cells. In many people with diabetes, pancreatic cells are not functional, causing a chronic and potentially fatal insulin deficiency that can only be controlled through dai...

Hyperbaric oxygen therapy (HBOT) can relieve self-reported symptoms and side-effects of radiotherapy against cancer in the pelvic region, a study shows. After 30-40 sessions in a hyperbaric chamber, many patients experie...

Drug addiction is a vicious cycle of reward and withdrawal. Chronic users often relapse because of the unpleasant physical and psychological symptoms they experience when they stop taking the drug. Now, researchers repor...

Scientists have developed an ultrasensitive new test to detect abnormal forms of the protein tau associated with uncommon types of neurodegenerative diseases called tauopathies. This advance gives them hope of using cere...

A recent study has revealed more details about how the synaptonemal complex performs its job, including some surprising subtleties in function.

Computational biologists have devised a software tool that can play a high-speed 'Match Game' to identify bioactive molecules and the microbial genes that produce them so they can be evaluated as possible antibiotics and...

Virtual-reality researchers have developed a virtual-walking system that records a person's walking and re-plays it with vision and foot vibrations. Psychological experiments showed that the sensation of walking and tele...

Using optogenetic and chemogenetic techniques, researchers have identified brain circuits underlying hunger-induced changes in the preferences for sweet and aversive tastes in mice. These circuits involved Agouti-related...

E-cigarette use is rising at concerning levels among both smokers and non-smokers, and new research data suggests that even short-term e-cig use can cause cellular inflammation in never-smoker adults. Inflammation from s...
