Climate change is exacerbating human-wildlife conflicts by straining ecosystems and altering behaviors, both of which can deepen the contacts -- and potential competition -- between people and animals. In an article published July 30 in the journal Science, Briana Abrahms, a University of Washington assistant professor of biology, calls for expanding research into the many ways that climate change will impact the complex interplay between human activities and wildlife populations.

A new study shows that people who eat a diet that includes at least half a serving per day of foods high in flavonoids like strawberries, oranges, peppers and apples may have a 20% lower risk of cognitive decline. The research is published in the July 28, 2021, online issue of Neurology, the medical journal of the American Academy of Neurology. The study looked at several types of flavonoids, and found that flavones and anthocyanins may have the most protective effect.

Although cats have lived alongside humans for millennia, it remains a dogs' world. This bias has historically bled into science as well. It's time for cats to get their day, argues veterinary medicine expert Leslie Lyons (@LyonsLab) in a Forum published July 28 in the journal Trends in Genetics. Cats, she says, have the potential to be a valuable model organism for geneticists, as the feline genome is ordered similarly to humans.

Machine learning can accurately predict cardiovascular disease and guide treatment--but models that incorporate social determinants of health better capture risk and outcomes for diverse groups, finds a new study by researchers at New York University's School of Global Public Health and Tandon School of Engineering.

Results of a compassionate-use study released in STEM CELLS Translational Medicine show promising results for treating muscular dystrophies with mesenchymal stem cells (MSCs) derived from Wharton's jelly (WJ), a substance found in the umbilical cord.

Cell-free DNA (cfDNA) shed into the blood was discovered in the late 1940s but with rapid advances in genomics and computational analytics in just the past few years, researchers at Georgetown Lombardi Comprehensive Cancer Center now believe that studying tags, or modifications to this type of DNA, may lead to a better understanding of how to assess, and possibly modulate, treatment approaches for cancer and other diseases. Their perspective, drawn from a review of studies to date, appears July 27 in Frontiers in Genetics.
