Japanese scientists at Tokyo University of Agriculture and Technology (TUAT) have found that for stroke patients, observing their own hand movements in a video-assisted therapy -- as opposed to someone else's hand -- could enhance brain activity and speed up rehabilitation.
Researchers have proposed a way to measure the ecological impact of global food wastage due to excessive consumption. Published in Frontiers in Nutrition, the results suggest that direct food waste -- thrown away or lost from field to fork -- is a mere hors-d'uvre.
Animal-assisted therapy has many benefits in health care. Yet, its biological and psychosocial effects in the military are unknown, especially for injured, airlifted patients. Researchers teamed up with a non-profit animal organization that trains therapy dogs to see if an animal-assisted intervention could reduce stress in this setting. Results showed that levels of the stress biomarkers cortisol, alpha-amylase, and immunoglobulin A, significantly decreased after a 20-minute intervention with the dogs, regardless of post-traumatic stress symptom severity.
A team of neuroscientists at the University of Tuebingen and MIT's Picower Institute for Learning and Memory shows how to distinguish four classes of brain cells by their spike waveforms. The advance offers brain researchers the chance to better understand how different kinds of neurons are contributing to behavior, perception and memory, and how they are malfunctioning in cases of psychiatric or neurological diseases.
A team of scientists from Weill Cornell Medicine and The Rockefeller University has illuminated the basic mechanism of Piezo proteins, which function as sensors in the body for mechanical stimuli such as touch, bladder fullness, and blood pressure. The discovery is a feat of basic science that also opens up many new paths of investigation into the roles of Piezo proteins in human diseases and potential new therapeutic strategies.
Researchers from the University of Wisconsin-Madison and Marshfield Clinic have found that there may be a much broader health risk to carriers of the FMR1 premutation, with potentially dozens of clinical conditions that can be ascribed directly to carrying it. The researchers employed machine learning to mine decades of electronic health records of nearly 20,000 individuals.
Rutgers and other scientists have discovered how brown fat, also known as brown adipose tissue, may help protect against obesity and diabetes. Their study in the journal Nature adds to our knowledge about the role of brown fat in human health and could lead to new medications for treating obesity and type 2 diabetes.
New research on one of the oldest and most complete fossil primate skulls from South America shows instead that the pattern of brain evolution in this group was far more checkered. The study, published today in the journal Science Advances and led by researchers from the American Museum of Natural History, the Chinese Academy of Sciences, and the University of California Santa Barbara, suggests that the brain enlarged repeatedly and independently over the course of anthropoid history.
People in Croatia during the 5th to 6th centuries may have used cranial modifications to indicate their cultural affiliations, according to a study published Aug. 21, 2019 in the open-access journal PLOS ONE led by Ron Pinhasi of the University of Vienna and Mario Novak of the Institute for Anthropological Research in Zagreb, Croatia.
A new finding has changed the understanding of the molecular mechanisms leading to atrial fibrillation.
