Many adults can remember the days when their screen time was limited to Saturday morning cartoons, as well as their class’s weekly visit to the computer lab to play Oregon Trail. It was a quick half-hour of fatigued oxen, snakebites, and surprise bouts of dysentery.Over the past few decades, screen time has expanded from an occasional treat to a full-day affair. People of all ages stare at screens for work, school, and entertainment. Within the last two decades, scientists have increasingly st ...read more
Although volcanic eruptions can strike when least expected, they sometimes give off warning signs that can be captured by advanced technology. One innovative way to monitor eruptions is now being put to the test at the Reykjanes Peninsula, a hotbed of volcanic activity in Iceland. In a new study, researchers have reported the successful progress of an eruption warning system that uses distributed acoustic sensing (DAS), which can anticipate volcanic activity through magma movements beneath the s ...read more
Instead of targeted, aggressive attacks, sharks may bite humans out of self-defense. Within the media, sharks are often seen as bloodthirsty predators. However, shark attacks are rare and, for the most part, not fatal. Researchers explain how sharks bite for a number of reasons, including being territorial, deterring competition, and, of course, for predation. And now, researchers are looking at self-defense against humans as another possible reason, according to new research published in Front ...read more
Researchers developed a polymer-based therapy that can be injected following a heart attack that helps heart tissue heal. After administering it to rats, they demonstrated that it works up to five weeks later, they reported in the journal Advanced Materials.Heart attacks are a major health issue in the U.S., with about 805,000 people a year experiencing them — the equivalent of one every 40 seconds. About 12 percent of people who experience a heart attack will die from it.“Preventing heart f ...read more
It sounds like a setup for a horror movie: a meat-eating, cannibalistic caterpillar hiding in the shadows of a spiderweb and dressed in the remains of its former prey. But this incredible species, dubbed the “bone collector” and previously unknown to biologists, is real and living in a small section of forest on the Hawai'ian island of O’ahu.For the research team from the University of Hawai’i at Mānoa, this extremely rare discovery was 20 years in the making and shocked everyone involv ...read more
