Since the 1960s, computer chips have been built using a process called photolithography. But in the past five years, chip features have gotten smaller than the wavelength of light, which has required some ingenious modifications of photolithographic processes. Keeping up the rate of circuit miniaturization that we’ve come to expect — as predicted by Moore’s Law — will eventually require new manufacturing techniques.

Scientists have formulated a system that uses ultrasound images to accurately work out the likelihood of an ovarian growth being cancerous. The team – from international institutions including Imperial College London and the University of Leuven – say the system could allow medics to classify a tumour as cancerous before surgery, and could potentially improve outcomes for patients. In a study looking at the tumours of 4,500 women...

In atherosclerosis, plaque builds up on the inner walls of arteries that deliver blood to the body. Studying mice and tissue samples from the arteries of patients, researchers at Washington University School of Medicine​ in St. Louis suggest this accumulation is driven, at least in part, by processes similar to the plaque formation implicated in brain diseases such as Alzheimer’s and Parkinson’s.

Glioblastoma multiforme is a particularly deadly cancer. A person diagnosed with this type of brain tumor typically survives 15 months, if given the best care. The late Senator Ted Kennedy succumbed to this disease in just over a year.  But scientists at the Salk Institute have discovered a key to how these tumor cells proliferate so quickly —and ways to turn this engine of tumor growth into a target for cancer treatment.

In the first study of its kind, a team of international scientists led by UT Southwestern Medical Center and UCLA researchers have identified a dozen inherited traits related to sleep, wake, and activity cycles that are associated with severe bipolar disorder. Researchers also were able to tie the traits to specific chromosomes, providing important clues to the genetic nature of the disorder, as well as potential new avenues for prevention...

Have you ever noticed that when you are in the midst of, let’s say, shoe shopping or shortly after, you find yourself checking out the shoes of the people you see on the street or in the bus far more often than usual? Similarly, when you get out of the hair salon you start being much more...

New research shows that current approaches to genome analysis systematically miss detecting a certain type of complex mutation in cancer patients’ tumors. Further, a significant percentage of these complex mutations are found in well-known cancer genes that could be targeted by existing...

A new study led by scientists at The Scripps Research Institute (TSRI) shows that an antidepressant drug, called mianserin, can extend the “young adult” state in roundworms, a common model of aging.
In the study, published today in the journal eLife, the researchers...
