A surprising connection between cosmology and quantum mechanics could unveil the secrets of space and time --

As consumers around the world have become increasingly dependent on electronics, the transistor, a semiconductor component central to the operation of these devices, has become a critical subject of scientific research. ...

Brain balls sound like something straight out of a Tim Burton movie: starting as stem cells harvested from patients, they eventually develop into masses of living neurons, jumbled together in misshapen blobs. Just like t...

The discovery of a Higgs boson in 2012 by the ATLAS and CMS experiments marked a milestone in the history of particle physics. It confirmed a long-standing prediction of the Standard Model, the theory that comprises our ...

Some dividing human cells are 'kicking the can down the road,' passing on low-level DNA damage to offspring, causing daughter cells to pause in a quiescent, or dormant, state previously thought to be random in origin, re...

In a surprising finding, weekly doses of glucocorticoid steroids, such as prednisone, help speed recovery in muscle injuries, reports a new study. The weekly steroids also repaired muscles damaged by muscular dystrophy. ...

By using induced pluripotent stem cells to create endothelial cells that line blood vessels in the brain for the first time for a neurodegenerative disease, neurobiologists and colleagues have learned why Huntington's di...

Hundreds of thousands of children with chronic illnesses who used to die are now surviving their disease and treatment--which is amazing. But their brains are being damaged in the process of keeping them alive. This firs...

Investigators are hopeful that their study involving small molecules in saliva will help identify those at risk of developing Alzheimer's disease.

At a recent workshop on blind analysis, researchers discussed how to keep their expectations out of their results. Scientific experiments are designed to determine facts about our world. But in complicated analyses, ther...

The last 10 months were the driest July to April for southern England in records stretching back more than 100 years, figures reveal

An international team of researchers is now one step closer to eliminating a deadly parasitic disease responsible for killing hundreds of thousands of people around the world every year.

The evidence is clear. Physical activity is associated with a reduced risk of Alzheimer's disease, a new study concludes.

A team of investigators has identified key inflammatory cells involved in nonalcoholic fatty liver disease. Current treatment for the disorder involves changes to diet, yet no medication has been approved for treatment. ...

A mutation in an immune system gene rapidly rose in frequency in Southeast Asia approximately 50,000 years ago because it likely conferred protection against leprosy. The findings show that the gene variant, called HLA-B...

Scientists used genome sequencing to discover that an otherwise rare strain of a superbug was found in more than one-third of the Houston patients studied.

Although the absolute difference in US county-level cardiovascular disease mortality rates have declined substantially over the past 35 years for both ischemic heart disease and cerebrovascular disease, large differences...

Among patients with knee osteoarthritis, an injection of a corticosteroid every three months over two years resulted in significantly greater cartilage volume loss and no significant difference in knee pain compared to p...

Among patients with a certain type of heart failure and iron deficiency, high-dose iron pills did not improve exercise capacity over 16 weeks, according to a study.

A team of scientists has used the cells of AHDS patients to recreate not only the disease, but a mimic of the patient's blood-brain barrier in the laboratory dish using induced pluripotent stem cell technology.

Development of age-related macular degeneration (AMD) could be arrested by switching from a high-glycemic to a low-glycemic diet, suggests a new study conducted in mice.

3-D printed bioprosthetic mouse ovaries restored fertility in infertile mice and produced healthy mouse pups. The mothers also were able to nurse their pups. The research is targeted to women whose cancer treatments impa...
