Across the South Pole’s frozen expanse, there lives only one purely terrestrial animal: a tiny insect called the Antarctic midge. This flightless creature, just 0.2 inches long, has eked out an existence in one of the world’s most unforgiving climates for some 30 million years, since its home continent split off from South America.Researchers have studied these midges for decades, documenting their impressive resistance to extreme conditions. But it was never clear how they endured the frigi ...read more
Stonehenge sits near the top of Britain’s most iconic landmarks, but a lesser-known precursor to this ancient site may be responsible for its lasting impact as an archaeological titan. The Flagstones site, a circular enclosure in Dorset, England, now predates Stonehenge according to new research, suggesting that it could possibly be the oldest structure of its kind in the country. The study, recently published in Antiquity, has established that the circular enclosure of Flagstones was constru ...read more
Microplastics. They’re in the soil; they’re in the ocean; and they’re even in the air, poised to invade our respiratory systems and to harm our health. But how, exactly, do they make their way into the atmosphere?Some studies have suggested that these tiny pieces of plastic — at most around 5 millimeters across — take to the air from the ocean. Ocean spray shoots them into the atmosphere, these studies say, positioning these minuscule pollutants to enter our bodies when we breathe. But ...read more
Skin is a marvel. It’s flexible yet firm, helps control body temperature, and protects our internal organs. It also can heal itself after certain injuries. Skin’s self-healing properties are partially behind the inspiration for new hydrogel research. Researchers from Aalto University and the University of Bayreuth have developed a new hydrogel with self-healing abilities that are similar to skin. These findings, published in Nature Materials, may lead to further developments in soft robotic ...read more
Although many of us like to indulge from time to time, it turns out that a high-fat diet can alter the brain after just a few days, even in healthy adults.A study published in Immunity & Ageing reveals that eating a diet high in saturated fat for as short as three days can cause memory problems and brain inflammation in older adults. These results add to the already lengthy list of side effects of a fatty diet and suggest that it isn’t only overweight individuals who should be worried.The ...read more
