  • Look out, invasive species: The robots are coming
    on September 16, 2019 at 3:40 pm

    Researchers published the first experiments to gauge whether biomimetic robotic fish can induce fear-related changes in mosquitofish, aiming to discover whether the highly invasive species might be controlled without toxicants or trapping methods harmful to wildlife. Their findings indicate that even brief exposure to a robotic replica of the mosquitofish's primary predator can provoke meaningful avoidance behaviors and physiological changes associated with the loss of energy reserves, potentially translating into lower rates of reproduction.

  • Gutsy effort to produce comprehensive study of intestinal gases
    on September 16, 2019 at 1:20 pm

    Chemical engineers have traced the journey of gases through the gut while further developing a non-invasive, gas-capturing capsule.

  • Ancient Australia was home to strange marsupial giants, some weighing over 1,000 kg
    on September 13, 2019 at 11:14 pm

    Palorchestid marsupials, an extinct group of Australian megafauna, had strange bodies and lifestyles unlike any living species.

  • Microbes make chemicals for scent marking in a cat
    on September 13, 2019 at 6:30 pm

    Domestic cats, like many other mammals, use smelly secretions from anal sacs to mark territory and communicate with other animals. A new study shows that many odiferous compounds from a male cat are actually made not by the cat, but by a community of bacteria living in the anal sacs.

  • Elaborate Komodo dragon armor defends against other dragons
    on September 12, 2019 at 5:43 pm

    Just beneath their scales, Komodo dragons wear a suit of armor made of tiny bones. These bones cover the dragons from head to tail, creating a 'chain mail' that protects the giant predators. However, the armor raises a question: What does the world's largest lizard -- the dominant predator in its natural habitat -- need protection from?

  • Why do birds migrate at night?
    on September 12, 2019 at 4:05 pm

    Researchers found migratory birds maximize how much light they get from their environment, so they can migrate even at night.&nbs

  • Reconstructing the evolution of all species
    on September 11, 2019 at 6:27 pm

    By looking into fossil teeth from almost 2 million years old rhinos, researchers have launched a new molecular method for studying the evolutionary history of fossil species dating back millions of years.

  • Can a DNA construction kit replace expensive antibody medication?
    on September 11, 2019 at 11:42 am

    Researchers have developed a technique to make sheep produce new antibodies simply by injecting the DNA building blocks. The study in animals with a similar size as humans brings us a step closer to the clinical use of antibody gene therapy.

  • Electric eel produces highest voltage discharge of any known animal
    on September 10, 2019 at 5:43 pm

    South American rivers are home to at least three different species of electric eels, including a newly identified species capable of generating a greater electrical discharge than any other known animal, according to a new analysis of 107 fish collected in Brazil, French Guiana, Guyana and Suriname in recent years.

  • How salamanders harness limb regeneration to buffer selves from climate change
    on September 10, 2019 at 5:43 pm

    Researchers have shown for the first time that salamanders inhabiting the Southern Appalachian Mountains use temperature rather than humidity as the best cue to anticipate changes in their environment. Significantly, they observed that these salamanders actually harness their unique ability to regenerate limbs to rapidly minimize the impact of hot temperatures. The findings may have implications for other animals and even plants.

  • Male honeybees inject queens with blinding toxins during sex
    on September 10, 2019 at 12:00 pm

    They say love is blind, but if you're a queen honeybee it could mean true loss of sight. New research finds male honeybees inject toxins during sex that cause temporary blindness.

  • Acute periodontal disease bacteria love colon and dirt microbes
    on September 9, 2019 at 9:08 pm

    Mythbuster: The idea that bacterial collaborations within microbiomes, like in the mouth, have evolved to be generous and exclusive very much appears to be wrong. In an extensive experiment, lavish collaborations ensued between random microbes. And some bacteria from the same microbiome were stingy with one another.

  • Birds string together meaningless sounds to make 'words'
    on September 9, 2019 at 8:01 pm

    A new study sheds light on whether animal vocalizations, like human words, are constructed from smaller building blocks. By analyzing calls of the Australian chestnut-crowned babbler, the researchers have for the first time identified the meaning-generating building blocks of a non-human communication system.

  • Realistic robots get under Galápagos lizards' skin
    on September 5, 2019 at 1:37 am

    Male lava lizards are sensitive to the timing of their opponents' responses during contest displays, with quicker responses being perceived as more aggressive, a study suggests.

  • Squirrels listen in to birds' conversations as signal of safety
    on September 4, 2019 at 6:13 pm

    Grey squirrels eavesdrop on the chatter between nearby songbirds as a sign of safety.

  • Super shrimp could increase yield and prevent human disease
    on September 4, 2019 at 5:06 pm

    Single-sex prawns could help alleviate poverty, reduce disease and protect the environment, according to researchers v who have developed a monosex prawn that may make this winning trifecta possible.

  • Ancient animal species: Fossils dating back 550 million years among first animal trails
    on September 4, 2019 at 5:06 pm

    A geoscientist calls the unearthed fossils, including the bodies and trails left by an ancient animal species, the most convincing sign of ancient animal mobility, dating back about 550 million years.

  • T. Rex had an air conditioner in its head, study suggests
    on September 4, 2019 at 4:53 pm

    Tyrannosaurus rex, one of the largest meat-eating dinosaurs on the planet, had an air conditioner in its head, suggest scientists who are challenging over a century of previous beliefs.

  • Cone snail's strike is one of the quickest in the animal kingdom
    on August 30, 2019 at 1:21 pm

    With the use of ultra-high-speed videography, biologists have shed light on the hunting mechanism of the cone snail Conus catus. The researchers identified the snail's hydraulically propelled feeding structure as the quickest movement among mollusks by an order of magnitude.

  • Crows consciously control their calls
    on August 27, 2019 at 6:57 pm

    Crows can voluntarily control the release and onset of their calls, suggesting that songbird vocalizations are under cognitive control.
