  • Computer program designed to calculate the economic impact of forest fires
    on May 20, 2019 at 3:11 pm

    High temperatures and low humidity—summer is approaching and with it the fire season. The lack of precipitation also makes 2019 a year characterised by risk, so some Spanish regions, such as the Balearic Islands, have taken swift action and already begun their prevention operations. According to a report from the Ministry of Agriculture, Fisheries and Food, every year there are an average of 12,000 fires and outbreaks, affecting more than 100,000 hectares of forest. This means not only […]

  • Bonobo moms play an active role in helping their sons find a mate
    on May 20, 2019 at 3:00 pm

    Many social animals share child-rearing duties, but research publishing May 20 in the journal Current Biology finds that bonobo moms go the extra step and actually take action to ensure their sons will become fathers. From physically preventing other males from mating to bringing their sons in close proximity to ovulating females, bonobo moms bring new meaning to the notion of being overbearing—but in so doing, they increase their sons' chance of fatherhood three-fold. […]

In 4 million-year old lake sediments from what is now the Armenian highlands, they found evidence of an astonishing variety of carp. Thanks to "virtual palaeontology," the researchers identified four closely-related species of Mesopotamian barb fish, so-called scrapers. They believe that these species lived together in a […]

  • Advanced civilizations could be communicating with neutrino beams
    on May 20, 2019 at 1:50 pm

    In 1960, famed theoretical physicist Freeman Dyson made a radical proposal. In a paper titled "Search for Artificial Stellar Sources of Infrared Radiation," he suggested that advanced extra-terrestrial intelligences (ETIs) could be found by looking for signs of artificial structures so large that they encompass entire star systems (also known as megastructures). Since then, many scientists have come up with their own ideas for possible megastructures. […]

    Identifying the optimal drug treatment is like hitting a moving target. To stop disease, small-molecule drugs bind tightly to an important protein, blocking its effects in the body. Even approved drugs don't usually work in all patients. And over time, infectious agents or cancer cells can mutate, rendering a once-effective drug useless. […]

  • Water nanodroplets zip across graphene faster than a cheetah
    on May 20, 2019 at 1:30 pm

    In a new study, researchers have propelled water nanodroplets across a graphene surface at speeds of up to 250 km (155 miles) per hour—which, for comparison, is about twice as fast as a sprinting cheetah. The water droplets' ultrafast velocities don't require any pump, but instead occur simply due to the geometric patterns on the graphene surface, which create different contact angles at the front and back of the moving droplets to propel them forward. […]
