The Mekong River, one of the world’s largest, traverses six Southeast Asian countries and supports the livelihoods of millions of people. New efforts to provide hydroelectric power to a growing and modernizing population include more than eight proposed main-stem dams and 60 or more existing tributary dams in the lower Mekong basin. A new article from University of Illinois and Iowa State University scientists lays out what dam construction could mean for residents and the environment in the region.

Researchers have found strong evidence that environmental exposures, including air pollution, affect gene expressions associated with respiratory diseases much more than genetic ancestry.

More than 11,000 people died during the Ebola outbreak in West Africa from 2013-16, demonstrating both the deadly nature of the virus and the limitations of the medication used to fight it.

Scientists have developed a new therapy to combat deadly bacteria that is infecting hospital patients worldwide. The new therapy—a biocide that is able to target antibiotic-defiant bacteria such as Methicillin-resistant Staphylococcus aureus (MRSA)—was developed by scientists at the University of Waterloo and University of Manitoba. “We wanted to be able to help vulnerable patients suffering from chronic infections,” said Emmanuel Ho, a professor in the School of Pharmacy at the University of Waterloo. “Once they’re infected with a resistant strain of bacteria it’s very difficult to get them well again.”

Diagnosis of Zika infection is complex. Molecular tests for exposure are only reliable in the first two to three weeks after infection while the virus is circulating in the bloodstream. Antibody tests are confounded by cross-reactivity of antibodies to Zika with dengue, yellow fever, and Japanese encephalitis viruses following infection or vaccination. A new blood test called ZIKV-NS2B-concat ELISA is faster, less expensive, and extends the window of accurate detection from weeks to months after the onset of infection, giving clinicians a powerful new tool to screen for Zika throughout pregnancy.

Magnetism and light have been combined in a test that can diagnose malaria in under two minutes without the need to take blood.

Move aside blueberries, cranberries and strawberries, there’s a new contender for the title of healthiest berry for us to eat. And you won’t find it in the grocery store.

It would be overkill to say that the carrot you eat today has very little nutrition in it—especially compared to some of the other less healthy foods you likely also eat—but it is true that fruits and vegetables grown decades ago were much richer in vitamins and minerals than the varieties most of us get today. The main culprit in this disturbing nutritional trend is soil depletion: Modern intensive agricultural methods have stripped increasing amounts of nutrients from the soil in which the food we eat grows. Sadly, each successive generation of fast-growing, pest-resistant carrot is truly less good for you than the one before.

Imagine losing a limb. Now imagine that on top of that loss, you feel pain, not just at the site of amputation, but in the missing limb itself as your brain tries to make sense of scattered signals.
