  • Indigenous hunters have positive impacts on food webs in desert Australia
    on February 17, 2019 at 7:25 pm

    Australia has the highest rate of mammal extinction in the world. Resettlement of indigenous communities resulted in the spread of invasive species, the absence of human-set fires, and a general cascade in the interconnected food web that led to the largest mammalian extinction event ever recorded. In this case, the absence of direct human activity on the landscape may be the cause of the extinctions, according to an anthropologist. […]

  • Laminitis research to help save horses and ponies
    on February 15, 2019 at 2:28 pm

    Laminitis -- a complex, common and often devastating disease -- is the second biggest killer of domestic horses. Now a body of important research on it has been compiled. […]

  • Exercise might improve health by increasing gut bacterial diversity
    on February 15, 2019 at 1:24 pm

    Research has suggested that the efficiency with which we transport oxygen to our tissues (cardiorespiratory fitness) is a far greater predictor of gut microbiota diversity than either body fat percentage or general physical activity. […]

  • 'Seeing' tails help sea snakes avoid predators
    on February 15, 2019 at 1:23 pm

    New research has revealed the fascinating adaptation of some Australian sea snakes that helps protect their vulnerable paddle-shaped tails from predators. […]

  • From vibrations alone, acacia ants can tell nibbles from the wind
    on February 15, 2019 at 1:23 pm

    Researchers find that the ants of the acacia tree are tipped off to the presence of herbivores by vibrations that run throughout the trees when an animal gets too close or begins to chew. As a result, the insects begin patrolling the acacia's branches more actively. Remarkably, the researchers show, the ants don't react when the trees' movements are caused only by the wind. […]

  • New live-imaging technique reveals cellular repair crew plugging leaky biological barrier
    on February 15, 2019 at 1:23 pm

    Suppose you live in a brick house and notice cracks in the mortar that let in cold air, rain and insect pests. You might call a brick mason to repair those leaks and to restore the barrier that keeps the great outdoors from getting inside. […]

  • Teens living in US states allowing medical marijuana smoke less cannabis
    on February 15, 2019 at 12:19 am

    According to a large-scale study of American high school students, legalizing medicinal marijuana has actually led to a drop in cannabis use among teenagers. The study used the results of an anonymous survey given to more than 800,000 high school students across 45 states to calculate the number of teens who smoke cannabis. […]

  • New molecular blueprint advances our understanding of photosynthesis
    on February 14, 2019 at 10:42 pm

    Researchers have used one of the most advanced microscopes in the world to reveal the structure of a large protein complex crucial to photosynthesis, the process by which plants convert sunlight into cellular energy. The finding will allow scientists to explore for the first time how the complex functions, and could have implications for the production of a variety of bioproducts, including plastic alternatives and biofuels. […]

  • Improved RNA data visualization method gets to the bigger picture faster
    on February 14, 2019 at 9:11 pm

    Like going from a pinhole camera to a Polaroid, a significant mathematical update to the formula for a popular bioinformatics data visualization method will allow researchers to develop snapshots of single-cell gene expression not only several times faster but also at much higher-resolution. This innovation by mathematicians will reduce the rendering time of a million-point single-cell RNA-sequencing (scRNA-seq) data set from over three hours down to just fifteen minutes. […]

  • Study examines how compound damaged DNA to understand its connection to cancer
    on February 14, 2019 at 8:31 pm

    In an effort to understand how colibactin, a compound produced by certain strains of E. coli, may be connected to the development of colorectal cancer, researchers are exploring how the compound damages DNA to produce DNA adducts. […]

  • Delays in banning wildlife trade put hundreds of species at risk
    on February 14, 2019 at 8:31 pm

    From parrots to lizards, hundreds of animal species could be at risk of extinction because of a policy process that responds slowly to scientific knowledge, according to a new study. […]

  • Oldest Americans most focused on reducing food waste

    The vast majority of Americans are paying attention to reducing food waste with the oldest being the most cognizant, according to the latest poll. […]

  • Dog burial as common ritual in Neolithic populations of north-eastern Iberian Peninsula
    on February 14, 2019 at 8:30 pm

    Coinciding with the Pit Grave culture (4200-3600 years before our era), coming from Southern Europe, the Neolithic communities of the north-eastern Iberian Peninsula started a ceremonial activity related to the sacrifice and burial of dogs. The high amount of cases that are recorded in Catalonia suggests it was a general practice and it proves the tight relationship between humans and these animals, which, apart from being buried next to them, were fed a similar diet to humans'. […]

  • Hop to it: Researchers evaluate rabbits' evolved resistance to myxoma virus

  • Parents don't pick favorites, at least if you're a Magellanic penguin
    on February 14, 2019 at 4:56 pm

    Researchers wanted to know how Magellanic penguin parents in South America balance the dietary demands of multiple chicks. They found that when a Magellanic penguin parent returns to its nest with fish, the parent tries to feed each of its two chicks equal portions of food, regardless of the youngsters' differences in age or size.
