Drug therapy may effectively treat a potentially life-threatening condition associated with cirrhosis and other chronic liver diseases, according to a new study.

How deformable cells are, and thus how stiff or squishy they are, plays an important role in retaining blood-forming stem cells in their marrow niches and thus preserving their long-term repopulation capabilities.

Current treatments for tuberculosis (TB) are very effective in controlling TB infection caused by Mycobacterium tuberculosis (Mtb). They don't, however, always prevent reinfection. Why this happens is one of the long-sta...

Mitochondria manufacture energy in every cell of the body, including heart muscle cells. A new study shows that cardiac mitochondria are abnormal in the offspring of mouse mothers that become obese due to a high-fat, hig...

Roughly a quarter of patients overdue for colorectal cancer screening mailed completed kits back within two months, even if they weren't given any kind of financial incentive.

In a surprising finding, researchers showed the protein NLRP6 aggravated the difficult symptoms of gastrointestinal graft-vs.-host disease. Knocking out this protein in mice led to significantly better survival and less ...

An inexpensive weight-loss drug approved 60 years ago for only short-term use also may be safe and effective for longer-term treatment, according to a new study.

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed medication for major depressive disorder (MDD), yet scientists still do not understand why the treatment does not work in nearly thirty per...

Women who have reached menopause are at a greater risk of developing osteoporosis, which can lead to bone fractures and long-term impairment of mobility. Studies have suggested a link between reduced bone density and low...

Researchers have identified two proteins that act as gatekeepers to dampen a potentially life-threatening immune response to chronic infection.

A new article explores the pathophysiological factors that link sleep disturbances and Alzheimer's disease. Better understanding of this connection may lead to potential diagnostics and therapeutics for Alzheimer's disea...

Teenagers who regularly eat breakfast with their parents have a more positive body image than those who skip the meal or do not eat with their family.

Combining carboplatin, a common chemotherapy drug, with everolimus, a drug that blocks mTOR, is effective at inducing apoptosis and slowing tumor growth in patients with pediatric low-grade glioma brain cancer.

Physicists at the University of Maryland have developed a powerful new method to detect radioactive material. By using an infrared laser beam to induce a phenomenon known as an electron avalanche breakdown near the mater...

Study finds some evidence of a positive link between early life anxiety and later alcohol use disorder. However, there was no consistent link between anxiety in childhood and drinking frequency or binge drinking.

Differences in serotonergic neuron morphology, along with altered gene expression have been identified in patients with MDD. The findings shed light on why some patients do not respond to SSRI antidepressants.

An asymmetry between matter and antimatter has been observed in the charm quark.

Did you know that music and diagnostic imaging have something in common? Sounds have a lower or higher pitch depending on the size of the object that creates them. Tubas and double basses are big and produce deep low-pit...

A single thundercloud is more powerful than even the most potent nuclear plants on Earth. Scientists used cosmic rays to prove it.

For the past two decades, scientists have constructed a variety of experiments, including cryogenic detectors and tanks of liquid xenon, around the world in hopes of spotting the scantest signs of elusive dark matter par...

The chemical reactions that give rise to life need enough liquid water and not too much ultraviolet light, which seems to be a rare combination in the galaxy
