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.
Some patients with atrial fibrillation or A-Fib need an ablation, which requires a catheter and an advanced 3D map of the heart. Researchers have developed the first algorithm that guides catheter movements and accurately detects A-Fib targets without 3D maps of the heart. In human simulations, this technique stops the catheter at the right target and identifies the source type with a 95.25% success rate and a 99 percent detection rate of scar tissue, regardless of scar size.
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.
This new study applied X-ray imaging to several 3-million-year-old fossils in order to untangle the story of key pigments in ancient animals and reveal how we might recognize the chemical signatures of specific red pigments in long extinct animals to determine how they evolved.
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.
Researchers have identified how the human brain is able to determine the properties of a particular object using purely statistical information: a result which suggests there is an 'inner pickpocket' in all of us.
Scientists have identified a new mechanism that accelerates aging in the brain and gives rise to the most devastating biological features of Alzheimer's disease. The findings also unify three long-standing theories behind the disease's origins into one cohesive narrative that explains how healthy cells become sick and gives scientists new avenues for screening compounds designed to slow or stop disease progression, something existing medications cannot do.
