“The inhabitants of the Border Cave in the Lebombo Mountains on the Kwazulu-Natal/eSwatini border were cooking starchy plants 170 thousand years ago,” says Professor Lyn Wadley, a scientist from the Wits Evolutionary Studies Institute at the University of the Witwatersrand, South Africa (Wits ESI). “This discovery is much older than earlier reports for cooking similar...
A new study led by Yale University researchers finds that scaling up use of methadone and buprenorphine — medications for treating opioid use disorder known as opioid agonist therapies (OATs) — could greatly reduce HIV transmission rates and prevent deaths in Ukraine, where the disease is epidemic among people who inject drugs. The study was...
Both species, humans and chimpanzees, can be extremely territorial, and territorial disputes between groups can turn violent, with individuals killing each other. In humans, such between-group competition can escalate to war and devastating loss of human life. Researchers from the Max Planck Institute for Evolutionary Anthropology studied wild Western chimpanzees to find out whether territorial...
A study out of the University of Hyogo in Awaji, Japan, details the stress-reducing benefits to office workers that even a small plant situated within easy viewing can impart. Masahiro Toyoda, Yuko Yokota, Marni Barnes, and Midori Kaneko explored the practical use of indoor plants to boost mental health among employees typically removed from exposure...
Cities in the “global south” – densely populated urban areas that are part of low-income countries in Asia, Africa and Latin America – should phase out pit latrines, septic tanks and other on-site methods of human waste management. Instead, cities should invest in sewage systems, according to a report from the World Resources Institute/Ross Center...
Tiny mealworms may hold part of the solution to our giant plastics problem. Not only are they able to consume various forms of plastic, as previous Stanford research has shown, they can eat Styrofoam containing a common toxic chemical additive and still be safely used as protein-rich feedstock for other animals, according to a new...
Researchers at Carnegie Mellon University found that digital storybooks that animate upon a child’s vocalization offer beneficial learning opportunities, especially for children with less developed attention regulation. “Digital platforms have exploded in popularity, and a huge proportion of the top-selling apps are educational interfaces for children,” said Erik Thiessen, associate professor of Psychology at CMU’s Dietrich...
The number of e-cigarette users who began vaping at age 14 or younger has more than tripled in the last five years, say University of Michigan researchers. Last year, 28% of e-cigarette users said they started no later than age 14, compared to about 9% in 2014. The findings appear online in the American Journal...
A new assessment of the Medicare Part D program based on a proposal from the West Health Policy Center finds that Medicare beneficiaries would save $29 billion if drug manufacturer rebates were used to reduce their out-of-pocket costs at the pharmacy counter through the Part D benefit – as long as these rebate savings are not also used to...
Knowing a company’s true sales can help determine its value. Investors, for instance, often employ financial analysts to predict a company’s upcoming earnings using various public data, computational tools, and their own intuition. Now MIT researchers have developed an automated model that significantly outperforms humans in predicting business sales using very limited, “noisy” data. In...
