When signals between the brain and one eye go awry, input from the other eye can become predominant, a condition called amblyopia or “lazy eye.” Amblyopia is common and it is typically treated by forcing the less dominant eye to adapt, either through lab-based training or wearing an eyepatch. But new research suggests that people may be able to use wearable augmented-reality technology to reduce this visual discrepancy as they go about everyday activities.

A new biomarker test developed by researchers at Georgetown Lombardi Comprehensive Cancer Center and their colleagues can help predict, with up to 90 percent certainty, which chemical compounds can cause DNA damage that could lead to cancer. The study was published early online the week of December 4, 2017, in PNAS.

Timing is critical for playing a musical instrument, swinging a baseball bat, and many other activities. Neuroscientists have come up with several models of how the brain achieves its exquisite control over timing, the most prominent being that there is a centralized clock, or pacemaker, somewhere in the brain that keeps time for the entire brain.

The first clinical study of a low-cost, hand-held jaundice detector invented by Rice University students couldn’t have come at a better time for NEST360°, an international team of scientists, doctors and global health experts preparing for a Dec. 11 competition for $100 million from the MacArthur Foundation. The money would allow the team to carry out its visionary plan to halve the number of newborn deaths in African hospitals within 10 years.

Foraging is a centuries-old practice, but many of the mushrooms in British Columbia are just now being identified through DNA sequencing and the enthusiasm of amateur collectors.

It’s no surprise that chemicals in smoke cause cancer, but a new study published in the Archives of Toxicology shows that some chemicals in cigarette smoke and industrial processes may be more dangerous than previously thought. Though most “low molecular weight polycyclic aromatic hydrocarbons” (LMW PAHs) have not been shown to cause cancer alone, the study shows that in common combinations, these chemicals can help to spark the disease.

There will soon be nothing that cannot be produced with 3D printing. However, the materials used for this process are still “dead matter” such as plastics or metals.

The harmful effects of being overweight have been underestimated, according to a new study that analysed body mass index (BMI), health and mortality data in around 60,000 parents and their children, to establish how obesity actually influences risk of death. The University of Bristol study is published today in the International Journal of Epidemiology today [Friday 1 December].

When we sleep, our organism goes through different phases of sleep, however the brain remains interconnected during non-REM sleep, which was thought not to happen. The finding by a European team of researchers has also made it possible to analyse the scientific basis of consciousness, an increasingly important field of neuroscience.

Endocrine disrupting chemicals (EDCs) are associated with a number of possible health issues.

EDCs are mostly produced by humans. They’re found in all sorts of things from pesticides and herbicides, and from cropland and livestock waste effluents and municipal and industrial waste to personal care products.
