Researchers have developed a noninvasive way for identifying the major functions of the gastrointestinal tract, enabling them to assess the efficacy of frequently controversial prebiotics and probiotics on gut microbial health.

Researchers have identified a natural alarm system — found inside human immune cells and called the CARD8 inflammasome — that recognizes active HIV protease and triggers a self-destruct program to eliminate the infected cell.

Researchers at the Marine Biological Laboratory have imaged the very beginning of
how the body axis is set, and their findings help answer a fundamental question.

Scientists have succeeded in imaging SARS-CoV-2 with a helium ion microscope. In contrast to the more conventional electron microscopy, the samples do not need a thin metal coating in helium ion microscopy. This allows interactions between the coronaviruses and their host cell to be observed particularly clearly.

Gaining more fat cells is probably not what most people want, although that might be exactly what they need to fight off diabetes and other diseases. How and where the body can add fat cells has remained a mystery - but two new studies from UT Southwestern provide answers on the way this process works.

A research team led by Northwestern and Cornell universities has developed a new manufacturing platform that can quickly make vaccines at the point of care, ensuring they will not go to waste and expanding access to potentially life-saving medications.

Scientists have discovered a new mechanism for Zika virus transmission from mothers to baby during pregnancy that accounts for both the fetus's greater susceptibility to first-trimester Zika infection and for the more serious congenital defects observed in early versus late pregnancy.

A team of scientists in Japan has developed a novel method to induce stem cell generation from the blood samples of dogs. Through this technique, the scientists hope to advance regenerative therapies in veterinary medicine.

A new British Heart Foundation funded study has found that the release of stored iron in heart cells may contribute to heart failure and could lead to the development of new drugs for the disease.

A mitochondrial hormone expressed by cells deep in the brain appears to play a role in improving metabolism and fighting off obesity, according to a new study in mice.
