One of the top stories of 2016 quietly exited much of the public’s consciousness in 2017. But it’s still a hot topic among scientists and for good reasons. After Zika emerged in the Western Hemisphere, it shook the Americas, as reports of infections and devastating birth defects swept through Brazil and Colombia, eventually reaching the […]
NEW ORLEANS — National flood maps are underestimating the risk for tens of millions of people in the United States. That’s the conclusion of researchers presenting a new study December 11 at the American Geophysical Union’s fall meeting. The U.S. Federal Emergency Management Agency estimates that about 13 million people live in a “1-in-100-year” floodplain […]
Living near a fracking site appears to be detrimental to infant health, a study eyeing the gas production practice in Pennsylvania suggests. Babies of moms living within one kilometer of a hydraulic fracturing, or fracking, site in the state had a 25 percent greater chance of being born underweight than did babies whose moms lived […]
An astonishing number of things that scientists know about brains and behavior are based on small groups of highly educated, mostly white people between the ages of 18 and 21. In other words, those conclusions are based on college students. College students make a convenient study population when you’re a researcher at a university. It […]
It doesn’t matter if it’s a burly rattler or a tiny garter snake. A deadly fungal disease that’s infecting snakes in the eastern and midwestern United States doesn’t appear to discriminate by species, size or habitat, researchers report online December 20 in Science Advances. The infection, caused by the fungal pathogen Ophidiomyces ophiodiicola, can cover […]
Viable synthetic DNA [Scientists] produced in a test tube a totally artificial copy of a type of DNA virus.… The particular type of viral DNA (called Phi X174) the researchers made is an extremely simple molecule of only five or six genes. Their achievement, however, lays the foundation for eventual synthesis of more complex DNAs. […]
Smell has a reputation as a second-rate human sense. But that assumption stinks once hunter-gatherers enter the picture. Semaq Beri hunter-gatherers, who live in tropical forests on the eastern side of the Malay Peninsula in Southeast Asia, name various odors as easily as they name colors, say psycholinguist Asifa Majid and linguist Nicole Kruspe. Yet […]
Johnny Juzang was 10 years old when "Linsanity" became a phenomenon. For two magical months, Jeremy Lin showed Juzang and others that it was possible for an Asian American basketball player to succeed at the highest level. Eleven years later, Juzang occupies that same role for a new generation of players. Juzang may not be […]
A fossil jaw unearthed in Israel is speaking up about when humans departed Africa. The jaw’s message, at least to its finders: That ancient exodus started much earlier than many researchers had assumed. Misliya Cave on Israel’s Mount Carmel has yielded what its discoverers regard as a partial Homo sapiens jaw with an estimated age […]
AUSTIN, Texas — A new artificial organ gives a new meaning to the phrase “making eyes.” For the first time, researchers used human cells to build a model of the surface of the eye that’s equipped with a fake eyelid that mimics blinking. This synthetic eye could be used to study and test treatments for […]
