How old is your dog in human years? And what factors contribute to a long and healthy life for a dog? For years, it’s been generally accepted that “dog years” are roughly human years times seven – that a 1-year-old puppy is like a 7-year-old child, and an 11-year-old elderly dog is like a 77-year-old […]

Each year, an estimated 15 million babies are born prematurely or preterm (defined as delivery before the 37th week of pregnancy), and this number is rising, according to the World Health Organization. Preterm babies are at greater risk of experiencing serious health problems. Over the last several decades, multiple studies have shown a link between poor […]

Previous studies have shown that wisdom is a personality trait underpinning mental health and well-being. Recently, researchers at University of California San Diego School of Medicine looked at gender differences relative to wisdom, using two different validated scales. The study, publishing in the February 3, 2022, online edition of Frontiers in Psychology, assessed gender differences in […]

Researchers have tested a variety of popular hacks for improving the fit of KN95 and surgical masks, and found that while some hacks do improve fit, they can also come at the cost of the wearer’s comfort. Proper fit is essential to the effectiveness of a face mask, especially for those in healthcare settings who […]

When you’re looking for a job, any number of factors can work against you. When you’re passed over for a job you seek because you’re told you’re “overqualified” it may be initially flattering, but it’s most likely not what you want to hear. But does being labeled as “overqualified” keep you from getting the job? […]

During the current pandemic, social distancing has been one tool used to reduce the spread of COVID-19. But data from a new study point to as much as a 27% increase in heart disease risk in postmenopausal women who experience both high levels of social isolation and loneliness. The findings of the prospective study, published in […]

A national poll provides a snapshot into public sentiment about the acceptability of violent protest against federal, state and local government, providing current insights about the state of U.S. democracy and safety of government officials. The study reveals that nearly one-quarter (23%) of Americans believe engagement in violent protest against the government can ever be […]

A powerful class of antibiotics called carbapenems can circumvent antibiotic resistance thanks to a particular chain of atoms in their structure. Now, a team of researchers from Penn State and Johns Hopkins University have imaged an enzyme involved in the creation of this chain to better understand how it forms — and perhaps replicate the […]

‘Quantum friction’ – a component of friction not present in classical physics, has been postulated by researchers in France to explain anomalies in the behaviour of water at carbon-based surfaces like graphite, graphene and carbon nanotubes. The phenomenon’s generality is not yet known, but it could potentially be useful in fields such as desalination that […]

Left-handed gold nanopropellers are more than 1000-fold more efficient as flu vaccine adjuvants in mice than their right-handed counterparts, scientists have discovered. This is the first time immune response has been shown to differ depending on nanoscale chirality. As biological molecules are often chiral, they usually interact differently with each enantiomer of a chiral molecule. […]
