Facial expression analysis reveals bronze medalists were more likely to smile on the podium than silver medalists, while gold medalists were displayed the happiest facial expressions.
Researchers isolated live SARS-CoV-2, the virus responsible for COVID-19, from the feces of patients who died as a result of coronavirus infection. Antigens to the virus were also found in post-mortem gastrointestinal surface cells. Isolating the live virus from fecal matter indicates evidence of the infectious virus in feces is a common manifestation of COVID-19. Researchers also found SARS-CoV-2 RNA on surfaces and bedding samples in hotel rooms used by two presymptomatic people who were later diagnosed with COVID-19.
Compared to the virus that caused the SARS epidemic in the early 2000s, SARS-CoV-2, the virus responsible for COVID-19, has evolved new strategies to bind to cell receptors, resulting in tighter binding. A new study identifies key mutations that potentially enabled the animal-to-human transmission of SARS-CoV-2. The study mapped out important binding sites on SARS-CoV-2 for antibody drugs to act on. If new drugs can bind to the sites on SARS-CoV-2, they will block the virus out of cells.
Specific algorithms and brain signatures can be used to tell when a person is focused, indicating who may be able to benefit from electrical stimulation to help boost attention. The findings could help improve a patient's ability to manage focus deficits associated with a range of mental health problems.
Eating a high-fat diet can help with the absorption of oral CBD for those with epilepsy. Previous studies have linked CBD to helping manage seizures associated with epilepsy.
Researchers have identified over 500 genetic variants which affect the use of, and addiction to, alcohol and tobacco.
Researchers have developed a 3D printed prototype for a bionic eye. The team successfully printed an array of light receptors onto a hemispherical surface. This advance could revolutionize restoring vision to those who have lost their sight.
In mice, social stress can increase risk factors for cardiovascular disease and shorten life span, researchers report.
Researchers have developed a new method of 3D printing that allows for electronics to be printed on the hand. The team also printed biological cells onto a skin wound of a mouse. They hope this new technique could lead to a new method for providing skin grafts and wound care.
