Cambridge researchers have discovered how T cells—an important component of our immune system—are able keep on killing as they hunt down and kill cancer cells, repeatedly reloading their toxic weapons.... Read more

Muscle is known to regenerate through a complex process that involves several steps and depends on stem cells. Now, a new study led by researchers at the Instituto de Medicina Molecular João Lobo Antunes (iMM; Portugal) and the University Pompeu Fabra (UPF Barcelona; Spain) and published today in the scientific...

In the two decades since the human genome was first sequenced, scientists have learned much about how the genome is organized and how widely it varies between people around the globe. A better view of how that genetic variation influences traits or disease risk could lead to new ways of... Read more

The onset of puberty, the developmental stage at which adolescents reach sexual maturity, is known to be associated with the activity of a specific class of neurons, namely gonadotropin-releasing hormone (GnRH) neurons. Past neuroscience research revealed that while these neurons are already activated before humans and other mammals are born,... Read more

Lateral flow tests are more accurate than previously reported and cannot be compared directly to how PCR tests work, finds a new paper led by UCL researchers.... Read more

Formula milk trials have a high risk of bias, authors almost always report favorable conclusions, transparency is lacking, and findings are selectively reported, finds a review of evidence from recently published trials in The BMJ today.... Read more

More than 40,000 allogeneic hematopoietic stem cell transplants are carried out worldwide every year, mostly for patients suffering from leukemia or other diseases of the hematopoietic system. Very often, the so-called graft-versus-host reaction occurs, an inflammatory disease that can affect different organs and is caused by an unwanted defense reaction... Read more

University of Ottawa researchers believe zebrafish may provide clues to understanding how the human nervous system develops since this fish experiences new movements similarly to how babies do after birth.... Read more

Have you heard of a fractional carbon dioxide (CO2) laser?... Read more

Clinical trials in pregnant women are challenging but crucial for saving lives and the advancement of new therapies and treatments for mothers and babies.... Read more

For most of the time since the first description of multiple sclerosis (MS) in 1868, the causes of this disabling disease have remained uncertain. Genes have been identified as important, which is why having other family members with MS is associated with a greater risk of developing the disease.... Read more

The Scandinavian winter swimming culture combines brief dips in cold water with hot sauna sessions—and now, a study of young men who participate regularly in these polar plunges finds that winter swimming may allow the body to adapt to extreme temperatures. The findings, publishing October 11 in the journal Cell... Read more

A commonly available oral diuretic pill approved by the U.S. Food and Drug Administration may be a potential candidate for an Alzheimer's disease treatment for those who are at genetic risk, according to findings published in Nature Aging. The research included analysis showing that those who took bumetanide—a commonly used and... Read more

In order to study colorectal cancer more efficiently, microbiome scientists from the University of Tartu have been able to characterize microbiome composition from sample tubes used in colorectal cancer screening for testing fecal occult blood.... Read more

Mesenchymal stem cells (MSCs) are thought to have great potential in the field of regenerative medicine, which has the aim of restoring damaged tissues. However, not much was known about in vivo plasticity of them—until now. Researchers have identified a subpopulation of MSCs that promote the healing of bone fractures... Read more
