From 2007 to 2009, a devastating yellow fever virus outbreak nearly decimated brown and black and gold howler monkey populations at El Parque El Piñalito in northeastern Argentina. An international research team tested if howlers who survived the outbreak had any genetic variations that may have kept them alive. In brown howlers, they found two mutations on immune genes that resulted in amino acid changes in the part of the protein that detects the disease.
More than 380,000 babies are born prematurely in the United States each year, according to the March of Dimes. 'Preemies' can be severely underweight babies and struggle to get the nutrients they need from breast milk alone, so neonatal intensive care units provide an additional milk fortifier, either in the form of cow's milk or manufactured from donor breast milk, to keep them healthy.
Two topical immunosuppressant medications commonly prescribed to treat skin conditions do not appear to increase the risk for the most common forms of skin cancer, despite package label warnings to the contrary.
Men at particular risk for HIV are very likely to consistently take prevention medication during vacations when their odds of contracting the virus are higher, according to a new study. The findings indicate that short-term use of pre-exposure prophylaxis (PrEP) medication could be a highly successful way to prevent the spread of HIV in men who have sex with men and have difficulty with long-term PrEP use. It may also work to transition men to long-term PrEP use.
As COVID-19 swept across the nation, most states went into lockdown -- new research and state-by-state data suggests that stay-at-home orders helped slow the pandemic significantly.
A new insight into cell signals that control cancer growth and migration could help in the search for effective anti-cancer drugs. A McGill-led study reveals key biochemical processes that advance our understanding of colorectal cancer, the third most common cancer among Canadians.
Your gut bacteria could say a lot about you, such as why you're diabetic or how you respond to certain drugs. But scientists can see only so much of the gastrointestinal tract to study the role of gut bacteria in your health. Purdue University researchers built a way to swallow a tool that acts like a colonoscopy, except that instead of looking at the colon with a camera, the technology takes samples of bacteria.
A new study by a team of researchers at the University of Toronto identifies the region of the brain's hippocampus that links low income with decreased memory and language ability in children. The research shows it is the anterior hippocampus that is associated with differences in cognition related to income.
Humans are not the only social animal struggling with new infectious diseases. This review examines the behavioral responses to emerging diseases across the animal kingdom from frogs and wolves to lobsters, bats, and humans. The paper also addresses whether or not technology helps when it comes to dealing with humans and social distancing.
Patients with undiagnosed flu symptoms who actually had COVID-19 last winter were among thousands of undetected early cases of the disease at the beginning of this year. In a new paper in The Lancet's open-access journal EClinicalMedicine, epidemiological researchers from The University of Texas at Austin estimated COVID-19 to be far more widespread in Wuhan, China, and Seattle, Washington, weeks ahead of lockdown measures in each city.
