Researchers have found in an embryo that activation of its genome does not happen all at once. Instead, it follows a specific pattern controlled primarily by the various sizes of its cells.

New research identifies a link between the long-term decline in manufacturing jobs -- accelerated during the Great Recession -- and reduced fertility rates.

About 90% of cancer deaths are due to metastases, when tumors spread to other vital organs, and a research group recently realized that it's not individual cells but rather distinct clusters of cancer cells that circulat...

A brain circuit in the mouse basal forebrain that is involved in perceiving the outside world, connects with and overrides feeding behaviors regulated by the hypothalamus.

Researchers report visual evidence supporting the presence of bacteria within the microarchitecture of the placental tissue.

Administering anti-inflammatory treatments that prevent inflammation as well as proresolution treatments that tamp down the body's inflammatory response to surgery or chemotherapy can promote long-term survival in experi...

Researchers have developed a new, scalable cell culture system that allows for detailed investigation of how host cells respond to infection with hepatitis B (HBV) and delta virus (HDV).

Using a rat model for high blood pressure (hypertension), a common chronic cardiovascular condition, researchers found that preexisting hypertension altered normal reflexes in the lungs to affect autonomic regulation of ...

New research offers insight into leptin, a hormone that plays a key role in appetite, overeating, and obesity. The findings advance knowledge about leptin and weight gain, and also suggest a potential strategy for develo...

New research shows that a specific gene is associated with an increased risk of cannabis abuse. The gene is the source of a so-called nicotine receptor in the brain, and people with low amounts of this receptor have an i...

Your parents were right: You should always try all foods! Food neophobia, or fear of new foods, may lead to poorer dietary quality and increase the risk factors associated with chronic diseases.

A new study on the behavior of water in cancer cells shows how methods usually limited to physics can be of great use in cancer research. The researchers have shown how a combination of neutron scattering and thermal ana...

Scientists are developing a new class of drugs to treat a common genetic kidney disease which is a major cause of kidney failure.

Researchers have discovered redundancies in the biochemical signalling pathways of immune cells. This finding has important implications for advances in cancer immunotherapy, among other areas.

Sleep patterns can predict the accumulation of Alzheimer's pathology proteins later in life, according to a new study. These findings could lead to new sleep-based early diagnosis and prevention measures in the treatment...

Large numbers of healthcare workers risk transmitting respiratory viruses to patients and co-workers by attending work even when they have symptoms, according to a new study. The study found that 95% of people working in...

Researchers report that an experimental drug called vosoritide, which interferes with certain proteins that block bone growth, allowed the average annual growth rate to increase in a study of 35 children and teenagers wi...

Researchers have discovered the mechanism behind how neural stem cells in fruit flies are activated to stimulate the generation of new brain cells.

Tumors and certain viral infections pose a challenge to the human body which the immune system typically fails to hand. In these diseases it switches to hypofunctional state that prevent adequate protection. A research t...

Researchers have identified a genetic mutation that caused an 11-year-old girl to suffer a fatal reaction to infection with the Hepatitis A virus (HAV). The study reveals that mutations in the IL18BP gene causes the body...

A new study connects the proximity of fracking to higher household concentrations of radon gas, the second leading cause of lung cancer in the US.

(American Institute of Physics) It sounds like an old-school vinyl record, but the distinctive crackle in the music streamed into Chris Holloway's laboratory is atomic in origin. The group spent years finding a way to di...
