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.

Pulmonary hypertension is a type of high blood pressure that affects the lungs of both animals and people. When tiny vessels in the lungs become narrowed or blocked, it becomes harder for blood to flow through and can ca...

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...

An unprecedented study mapping child deaths over almost two decades finds that nearly half of the 5.4 million under-5 deaths in 2017 can be attributed to differences in child death rates within and across countries.

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

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 ...

Despite humanity's best efforts to eradicate malaria, the disease struck more than 200 million people in 2017, according to the World Health Organization. Worse yet, the parasite that causes malaria is developing resista...

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...

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...

Our feline companions can pass parasites, pathogens and more on to us. (Credit: Lario/Shutterstock) A good snuggle with a cat can improve anyone's day -- well, assuming you don't have allergies. But like any other animal...

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...

Scientists have assembled a set of genetic sequences that enable the reference genome to better reflect global genetic diversity. The new sequences improve the utility of the human reference genome, a touchstone resource...
