Modern meteorological data collection gives us an unprecedented view into the real-time growth, track, and death of tropical cyclones. Recently, we watched as Hurricane Florence started as a tropical wave off the west coast of Africa, grew into a storm with Category 4 winds, and then made landfall on September 14 near Wrightsville Beach, North Carolina. At that point, with sustained winds down to 90 miles-per-hour, Florence was classified as merely a Category 1 storm. But after moving rapidly across the Atlantic, Hurricane Florence had slowed to a crawl before hitting the Carolina coast, turning the storm into a rain bomb that dropped more precipitation — 36 inches in one town — than all previous U.S. tropical cyclones save one, last year’s Hurricane Harvey. Fears of coastal flooding were rapidly replaced by the reality of prolonged, inland flooding.
Researchers have developed techniques to detect Lyme disease bacteria weeks sooner than current tests, allowing patients to start treatment earlier.
Researchers from the Institute of Evolutionary Medicine of the University of Zurich and the Adelaide Medical School have analyzed data from 178 countries and found a link between family size and cancer risk. Worldwide the incidence of various types of cancer increases with smaller family size. “And this relationship is independent of income, levels of urbanization and age,” explains Professor Maciej Henneberg, academic guest at UZH and senior author of the study.
The study, by Dr Indrani Roy at the University of Exeter, suggests that the natural phenomena such as solar eleven-year cycles and strong volcanic explosions play important roles in recent climate change which has been ‘underestimated’.
Nearly 15 percent of all chewing gum varieties sold promise to provide health-enhancing supplements to users, so Penn State researchers studied whether two vitamin-supplemented products were effective at delivering vitamins to the body. Their results validate the concept of gum as an effective delivery system for at least some vitamins.
Spring in America’s heartland is often wet. That makes its soil too soft for planting. One solution to that issue is tile drainage. Growers insert a series of pipes (drain tiles) under their fields, which drains water from the soil into nearby streams and lakes.
Why share food with non-family members when there is no immediate gain? An international team of researchers from the Max Planck Institute for Evolutionary Anthropology (MPI-EVA) in Leipzig, Germany, conducted observations of natural food sharing behavior of the chimpanzees of the Taï National Park, Ivory Coast. They found that chimpanzees who possess large, desirable food items, like meat, honey or large fruit share food with their friends, and that neither high dominance status nor harassment by beggars influenced possessors’ decisions to share.
Just like humans, young songbirds are thought to learn their vocalizations by listening to adults — a process that has been studied in the laboratory but never experimentally in the wild, until now.
Heat and lots of rainfall, thanks in part to Hurricane Florence, were the key factors in last month’s ranking as fourth hottest and third wettest September on record for the contiguous United States.
Half of mental health disorders arise before the age of 14, but most cases are not detected or treated until much later, according to the latest data from the World Health Organization.
