Geometry is key to T-cell triggering

Composite of a scanning electron micrograph and immunofluorescence image showing a T cell (SEM) on an array of clusters of T cell receptor ligands, fluorescently labeled red. The green fluorescent signal comes from phosphorylation of a component of the T cell receptor, indicating that triggering has occurred (i.e., the T cell has been stimulated). Credit: […]

Going beyond ‘human error’

Failures in highly technological environments, such as military aircraft, can be investigated using known tools like HFACS, the U.S. Department of Defense’s Human Factors Analysis and Classification System. However, because of some limitations, HFACS does not always highlight the deeper causal factors that contribute to such failures. In what might be the first application of […]

Horses get the flu, too

Flu vaccines for horses haven’t been updated in more than 25 years, but researchers have developed a new live equine influenza vaccine that’s safe and more protective than existing vaccines. Proactively preventing the spread of flu in animals is important, as animals are the most likely source of future human pandemics. Animals can be infected […]

Lonely and non-empathetic people more likely to make unethical shopping decisions

Lonely consumers are capable of behaving morally, but aren’t motivated to, according to new research from Binghamton University, State University of New York. “Consumers very often behave immorally. And while these behaviors are often legal, they are unethical and cost retailers billions each year,” said Jenny Jiao, assistant professor of management at Binghamton University. A […]

Higher aerobic fitness levels are associated with better word production skills in healthy older adults

Healthy older people who exercise regularly are less inclined to struggle to find words to express themselves, research led by the University of Birmingham has discovered. Researchers found that older adults’ aerobic fitness levels are directly related to the incidence of age-related language failures such as ‘tip-of-the-tongue’ states. The research, published today in Scientific Reports, […]
