Two-dimensional hybrid metal halide device allows control of terahertz emissions
Researchers have utilized two-dimensional hybrid metal halides in a device that allows directional control of terahertz radiation generated by a spintronic scheme. The device has better signal efficiency than conventional terahertz generators, and is thinner, lighter and less expensive to produce. Terahertz (THz) refers to the part of the electromagnetic spectrum (i.e., frequencies between 100 […]
Early accumulation of tau in the brain predicts memory decline in Alzheimer’s disease
Researchers at Karolinska Institutet in Sweden have compared how well different Alzheimer’s biomarkers predict the progression of the disease and its effect on the memory. They found that early accumulation of tau proteins in the brain as measured by PET scanner was more effective at predicting memory impairment than biomarkers in the cerebrospinal fluid or […]
Wiggling worms suggest link between vitamin B12 and Alzheimer’s
Worms don’t wiggle when they have Alzheimer’s disease. Yet something helped worms with the disease hold onto their wiggle in Professor Jessica Tanis’s lab at the University of Delaware. In solving the mystery, Tanis and her team have yielded new clues into the potential impact of diet on Alzheimer’s, the dreaded degenerative brain disease afflicting […]
5 Sneaky Signs Your Kid Is Struggling Being Back In School
Few back-to-school seasons have been as emotionally loaded as the start to the 2021 academic year. So many kids were stepping back into the classroom for the first time in 18 months — or ever. Children, parents, and teachers were elated, nervous, frustrated ― all of it. While the first month or so of school […]
Zebrafish anticipate the future to avoid virtual danger
Scientists from the RIKEN Center for Brain Science (CBS) and collaborators in Japan have discovered particular neurons in the brain that monitor whether predictions made by fish actually come true. By making use of a new virtual reality-outfitted aquarium where brain imaging of zebrafish can be done as they learn and navigate through virtual reality […]
Small but mighty: Microgreens go from trendy vegetables to functional food: Study suggests ‘gourmet’ sprouts have potential to help provide global nutrition security
Starting decades ago as fashionable, high-value gourmet greens, today microgreens have gained popularity among consumers for their nutritional profile and high content of antioxidant compounds. Now, a new study suggests that the tiny plants have the potential to help provide global nutrition security. As part of a project titled, “Food Resilience in the Face of […]
AAN Issues Social Media Position Statement
The American Academy of Neurology (AAN) recommended that neurologists and other neuroscience professionals have an explicit, systematic awareness of issues and ethics about using social media in medicine. The new position statement, from the AAN’s Ethics, Law, and Humanities Committee, spans everything from tweeting about research to online harassment, and addresses patient education as well […]
Power of stem cells harnessed to create cartilage tissue
Researchers at the University of Southampton have invented a new way to generate human cartilage tissue from stem cells. The technique could pave the way for the development of a much-needed new treatment for people with cartilage damage. Cartilage acts as a shock absorber in joints, but it is susceptible to damage through daily wear-and-tear, […]
Children who eat more fruit and veggies have better mental health
Children who eat a better diet, packed with fruit and vegetables, have better mental wellbeing — according to new research from the University of East Anglia. A new study published today is the first to investigate the association between fruit and vegetable intakes, breakfast and lunch choices, and mental wellbeing in UK school children. It […]
America’s Amputation Crisis May Soon Get Much Worse
Few medical procedures are as life-altering as an amputation. But statistics show hundreds of thousands of Americans have their limbs surgically removed each year because they don’t have access to adequate vascular screening and care. In the rural communities of North Carolina that we serve, the nearest “in-hospital” alternative to our office-based treatment locations is […]
