  • A paper battery powered by bacteria
    on August 19, 2018 at 8:07 pm

    In remote areas of the world, everyday items like electrical outlets and batteries are luxuries. Health care workers in these areas often lack electricity to power diagnostic devices, and commercial batteries may be too expensive. Today, researchers report a new type of battery -- made of paper and fueled by bacteria -- that could overcome these challenges. […]

  • Ants, acorns and climate change
    on August 17, 2018 at 7:03 pm

    The relatively swift adaptability of tiny, acorn-dwelling ants to warmer environments could help scientists predict how other species might evolve in the crucible of global climate change, according to biologists. […]

  • More workers working might not get more work done, ants (and robots) show
    on August 16, 2018 at 6:32 pm

    For ants and robots operating in confined spaces like tunnels, having more workers does not necessarily mean getting more work done. Just as too many cooks in a kitchen get in each other's way, having too many robots in tunnels creates clogs that can bring the work to a grinding halt. […]

  • Female mosquitoes get choosy quickly to offset invasions
    on August 16, 2018 at 3:43 pm

    Certain female mosquitoes quickly evolve more selective mating behavior when faced with existential threats from other invasive mosquito species, with concurrent changes to certain genetic regions, according to new research. […]

  • There is not one kind of 'good sperm' -- it depends on other qualities in the male, bird study shows
    on August 16, 2018 at 2:19 pm

    In a new study, researchers show that the same type of sperm is not always the best for all male birds. Depending on how attractive or dominant you are you might be more successful with longer or shorter sperm. […]

  • How plants protect themselves by emitting scent cues for birds
    on August 15, 2018 at 4:40 pm

    When plants are in distress or being fed on by insects, they have been known to send out sensory volatile cues that alert organisms in the area -- such as birds -- that they are in need of help. While research has shown that this occurs in ecosystems such as forests, until now, this phenomenon has never been demonstrated in an agricultural setting. […]

  • Light-engineered bacterial shapes could hold key to future labs-on-a-chip
    on August 14, 2018 at 5:41 pm

    Scientists have used light patterns to control the swimming speed of bacteria and direct them to form different shapes. […]

  • Young salmon may leap to 'oust the louse'
    on August 13, 2018 at 2:03 pm

    A study by aquatic ecologists reveals that young salmon may jump out of water to remove sea lice. […]

  • Wearable 'microbrewery' saves human body from radiation damage
    on August 9, 2018 at 9:51 pm

    The same way that yeast yields beer and bread can help hospital lab workers better track their daily radiation exposure, enabling a faster assessment of tissue damage that could lead to cancer. […]

  • In apoptosis, cell death spreads through perpetuating waves
    on August 9, 2018 at 6:12 pm

    In a cell, death is akin to falling dominoes: One death-inducing molecule activates another, and so on, until the entire cell is shut down, a new study finds. […]

  • Tiny tunnels inside garnets appear to be the result of boring microorganisms
    on August 9, 2018 at 3:25 pm

    Complex systems of microscopic tunnels found inside garnet crystals from Thailand are most likely the result of microorganisms making their homes inside these minerals, according to a new study. […]

  • Fat-blocking effect of nanofibers discovered
    on August 8, 2018 at 5:42 pm

    Tiny balls of nano-sized cellulose fibers added to food reduced fat absorption by up to half in laboratory and animal experiments, scientists report. […]

  • Scientists create biodegradable, paper-based biobatteries
    on August 8, 2018 at 5:41 pm

    The batteries of the future may be made out of paper. Researchers have created a biodegradable, paper-based battery that is more efficient than previously possible. […]

  • Those fragrances you enjoy? Dinosaurs liked them first
    on August 7, 2018 at 9:10 pm

    The compounds behind the perfumes and colognes you enjoy have been eliciting olfactory excitement since dinosaurs walked the Earth amid the first appearance of flowering plants, new research reveals. […]

  • Ancient virus defends koalas against new viral attacks
    on August 6, 2018 at 8:27 pm

    A new study in koalas uncovers how virulent retroviruses become harmless bits of 'junk DNA' over time. […]

  • African killifish becomes fastest maturing vertebrate on record
    on August 6, 2018 at 3:46 pm

    For most of the year, annual killifish persist as diapausing embryos buried in sediments across the African savannah. When rainwater fills small depressions across the landscape, the fish must hatch, grow, mature, and produce the next generation before the pool dries up. Researchers have found that these small fish condense their life cycle even more in the wild than expected based on studies in the lab. […]

  • Small birds fly at high altitudes towards Africa
    on August 6, 2018 at 2:42 pm

    A new study shows that small birds migrating from Scandinavia to Africa in the autumn occasionally fly as high as 4,000 meters above sea level -- probably adjusting their flight to take advantage of favorable winds and different wind layers. […]

  • The bark side of the force
    on August 6, 2018 at 2:42 pm

    What forces enable trees to stand upright? To grow straight, plants need a motor system that controls their posture by generating forces to offset gravity. Scientists have long thought that this motor force was controlled only by the internal forces induced in wood. In a new study, scientists show that bark is also involved in the generation of mechanical stresses in several tree species. […]

  • Eating crickets can be good for your gut, according to new clinical trial
    on August 3, 2018 at 5:46 pm

    A new clinical trial shows that consuming crickets can help support the growth of beneficial gut bacteria and that eating crickets is not only safe at high doses but may also reduce inflammation in the body. […]

  • Rethinking ketchup packets: New approach to slippery packaging aims to cut food waste
    on August 3, 2018 at 2:33 pm

    New research aims to cut down on waste -- and consumer frustration -- with a novel approach to creating super slippery industrial packaging. The study establishes a method for wicking chemically compatible vegetable oils into the surfaces of common extruded plastics, like those used for ketchup packets and other condiments. […]
