In the dizzying swirl of health-related websites, social media and smartphone apps, finding a reliable source of health information can be a challenge. A group of researchers from the Johns Hopkins University schools of medicine and public health, as well as the university's Applied Physics Laboratory, have mapped out a course to navigate that complicated landscape.

Rhythmic waves of brain activity cause us to see or not see complex images that flash before our eyes. An image can become practically invisible if it flashes before our eyes at the same time as a low point of those brain waves. We can reset that brain wave rhythm with a simple voluntary action, like choosing to push a button.

People who sleep fewer than 7 hours per night have lower levels of gene-regulating molecules, or microRNAs, which help dampen down inflammation in cells and support vascular health.

Dr. Stephanie McGrath found in a small study that 89 percent of dogs who received CBD in the clinical trial had a reduction in the frequency of seizures. Nine dogs were treated with CBD, while seven in a control group were treated with a placebo.

Researchers at the University of Washington unveiled a new strategy to keep proteins intact and functional in synthetic biomaterials for tissue engineering. Their approach modifies proteins at a specific point so that they can be chemically tethered to the scaffold using light. Since the tether can also be cut by laser light, this method can create evolving patterns of signal proteins throughout a biomaterial scaffold to grow tissues made up of different types of cells.

When thinking about ways to end global hunger, many scholars focus too narrowly on increasing crop yields while overlooking other critical aspects of the food system.

A new paper in JNCI Cancer Spectrum, published by Oxford University Press, is the first study to find that diets high in soy foods are associated with a decreased risk of osteoporotic bone fractures in pre-menopausal breast cancer survivors.

Following traumatic brain injury (TBI), xenon prevented early death, improved long-term cognition, and protected brain tissue in mice in a new study.
