New research using data from the Canadian Longitudinal Study on Aging (CLSA) reveals that employment stability and in-person work buffered older adults against depression during the first year of COVID-19.

An international team of researchers has identified an East African bat coronavirus capable of entering human cells.

Whilst the virus - Cardioderma cor coronavirus (CcCoV) KY43, or CcCoV-KY43 – can bind to a cell receptor found in the human lung, preliminary testing in Kenya suggests it has not spilled over into the local human population.

Rather than work on ‘live’ viruses, the scientists used a public database of known genetic sequences, Genbank, to select and synthesise alphacoronavirus ‘spike’ proteins, including 27 viruses originally isolated in bats, and screened these against a library of coronavirus receptors found in human cells.

Pregnancy-related deaths in the United States increased sharply during the COVID-19 pandemic, with the greatest impact seen among Black women, a new study suggests.

The federal policy requiring states to keep Medicaid beneficiaries enrolled during the COVID-19 pandemic extended postpartum Medicaid coverage nationwide and sharply increased the number of individuals remaining insured after childbirth, according to a Rutgers Health researcher.

From the Wright brothers’ first flight to the speedy development of COVID-19 vaccines, collaboration has been key to innovation. Paradoxically, even competitors can benefit from collaboration — when they hold different pieces of the same puzzle.

But these companies must strike a delicate balance, according to new research from the McCombs School of Business at The University of Texas at Austin. Ramkumar Ranganathan, associate professor of management, offers some principles for managing the balance between competition and collaboration — particularly when it involves sharing information. "Firms need to pay attention to these longer-term issues,” he says. “It’s very easy to look at the short term and think, ‘This alliance partner is giving me X amount of money to co-develop this technology. So, what if I don’t let this person talk to this other person for a few months? That shouldn’t matter, right?’ But it does matter.”

The global wildlife trade – especially in illegal and live-animal markets – is fueling the spread of diseases from animals to humans, according to a new study. The findings show that traded mammals are more than 40% more likely to harbor human-infecting pathogens, with species accumulating more shared pathogens the longer they remain in the trade. Close interactions between humans and wild animals create pathways for the spread of parasites and pathogens, sometimes triggering epidemics and pandemics. The global wildlife trade, which encompasses hunting, breeding, transport, retail, and pet ownership, poses particularly high risks of animal-to-human pathogen spillover. This trade has been linked to outbreaks ranging from HIV and Ebola to COVID-19 and mpox. While research has explored environmental and ecological factors that influence pathogen transmission, the dynamics of disease spread specifically within the wildlife trade and between humans and traded animals remain poorly understood.

Jérôme Gippet and colleagues analyzed 40 years of global wildlife trade data drawn from the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the Law Enforcement Management Information System (LEMIS), and the Dataset of Seized Wildlife and their intended uses (DSW) datasets. They then linked this to the CLOVER database, which catalogs over 190,000 mammal-pathogen associations, to identify which species are known to share pathogens with humans. Gippet et al. found that among the 2,079 mammal species involved in global trade, 41% were found to share at least one pathogen with humans, compared with only 6.4% of nontraded species, and that traded mammals are 1.5 times more likely to host pathogens transmissible to humans. According to the authors, this suggests that cross-species transmission is an inherent feature of wildlife trade. Species in live-animal markets and, to a lesser extent, those involved in illegal trade, host more pathogens than those traded solely as products or legally. What’s more, the findings show that the duration a species spends in trade further amplifies risk. Gippet et al. found that each decade a species is traded corresponds to one additional pathogen shared with humans, on average.
