M. Ehsan Hoque develops digital helpers that teach social skills

A growing band of digital characters that converse, read faces and track body language is helping humans to communicate better with one another. While virtual helpers that perform practical tasks, such as dealing with customer service issues, are becoming ubiquitous, computer scientist M. Ehsan Hoque is at the forefront of a more emotionally savvy movement. […]

Here’s yet more evidence that the mythical yeti was probably a bear

Campfire legends of massive, shaggy bipeds called yetis are grounded in a less mysterious truth: bears. Eight samples of remains such as fur, bones and teeth purportedly from mountain-dwelling yetis actually come from three different kinds of bears that live in the Himalayas, researchers report November 29 in the Proceedings of the Royal Society B. […]

Scientists are tracking how the flu moves through a college campus

COLLEGE PARK, Md. — Campus life typically challenges students with new opportunities for learning, discovery — and intimacy with germs. Lots of germs. That makes dormitories and their residents an ideal natural experiment to trace the germs’ paths. “You pack a bunch of college kids into a very small environment … we’re not known as […]

Microplastics are in our bodies. Here’s why we don’t know the health risks

Tiny particles of plastic have been found everywhere — from the deepest place on the planet, the Mariana Trench, to the top of Mount Everest. And now more and more studies are finding that microplastics, defined as plastic pieces less than 5 millimeters across, are also in our bodies. “What we are looking at is […]

Hints of Oort clouds around other stars may lurk in the universe’s first light

A thick sphere of icy debris known as the Oort cloud shrouds the solar system. Other star systems may harbor similar icy reservoirs, and those clouds may be visible in the universe’s oldest light, researchers report. Astronomer Eric Baxter of the University of Pennsylvania and colleagues looked for evidence of such exo-Oort clouds in maps […]

A new airplane uses charged molecules, not propellers or turbines, to fly

A newly designed airplane prototype does away with noisy propellers and turbines. Instead, it’s powered by ionic wind: charged molecules, or ions, flowing in one direction and pushing the plane in the other. That setup makes the aircraft nearly silent. Such stealth planes could be useful for monitoring environmental conditions or capturing aerial imagery without […]

Studies can be in vitro, in vivo and now ‘in fimo’ — in poop

Poop contains a lot of valuable scientific information. Researchers can monitor microbes, track enzyme activity or hunt for DNA to gather clues about overall health. There’s so much one can learn from the waste product that microbiologist Aadra Bhatt at the University of North Carolina at Chapel Hill decided there should be a word for […]

The CBD boom is way ahead of the science

A few months back, a new storefront appeared in my small Oregon town. Its shelves were packed with tinctures, jars of salve, coffee beans, bath bombs — even beard oil. This motley collection shared a single star ingredient: CBD. Produced by the cannabis plant, CBD is the straitlaced cousin of marijuana’s more famous component — […]

Chickens stand sentinel against mosquito-borne disease in Florida

For 40 years, they’ve held the front line in Florida’s fight against mosquito-borne diseases. And it turns out that the chickens standing sentinel in cities, marshes, woodlands and residential backyards are clucking good at their job. Last year, chickens in 268 coops in over a third of Florida’s counties provided scientists weekly blood samples that […]
