  • Party discipline for jumping genes
    on September 22, 2017 at 1:09 pm

    Jumping genes, transposons, are part of the genome of most organisms, aggregated into families and can damage the genome by jumping. How hosts suppress the jumping is well investigated. Why they still can jump has hardly been understood so far. Researchers investigated for the first time in all transposons of the host organism, which properties and host environments facilitate jumping. They showed that family affiliation is more important than position. […]

    on September 21, 2017 at 6:12 pm

    Poison frogs harbor some of the most potent neurotoxins we know, yet scientists have long wondered -- how do these frogs keep from poisoning themselves? Scientists are now a step closer to resolving that head-scratcher. And the answer has potential consequences for the fight against pain and addiction. […]

  • Heat-loving Australian ants believe in diversity, hint 74 species new to science
    on September 21, 2017 at 6:12 pm

    A genus of Australian ants, many of whose members prefer to forage in blistering temperatures of up to 50°C (122°F), is revised to include 74 new species. The ants include seed-eaters, ant and termite raiders, 'honeypot ants' that store nectar and honeydew, and numerous others whose biology is not yet understood. Some are bizarre: one species has eyes like inverted ice-cream cones. […]

  • Researchers discover new cattle disease and prevent it from spreading
    on September 21, 2017 at 2:17 pm

    Following genetic studies of deformed calves, research is able to uncover a previously unknown disease found among Holstein cattle. The breeding bull from which the mutation and thus the deformation originate has now been put down to prevent the disease from spreading further. […]

  • Tiny Brazilian frogs are deaf to their own calls
    on September 21, 2017 at 1:03 pm

    Pumpkin toadlets, found on the leaf litter of Brazil's Atlantic forest, are among the smallest frogs in the world. Scientists have now discovered that two species of these tiny orange frogs cannot hear the sound of their own calls. […]

    on September 21, 2017 at 1:02 pm

    A remote cave in Eastern Turkmenistan was found to shelter a marvelous cave-adapted inhabitant that turned out to represent a species and genus new to science. This new troglodyte is the first of its order from Central Asia and the first strictly subterranean terrestrial creature recorded in the country. […]

  • Efforts to save sea turtles are a 'global conservation success story'
    on September 20, 2017 at 10:21 pm

    A new study of the world's seven sea turtle species provides evidence that their numbers are growing overall (unlike many endangered vertebrates), thanks to years of conservation efforts that have played a key role in sea turtle recovery -- even for small sea turtle populations. […]

    on September 20, 2017 at 7:49 pm

    The answer to the question of why some organisms can regenerate major body parts while others, such as humans, cannot may lie with the body's innate immune system, according to a new study of heart regeneration in the Mexican salamander. […]

  • Plants combine color and fragrance to procure pollinators
    on September 20, 2017 at 6:47 pm

    Who knew that it's possible to predict the fragrance of a flower by looking at its color? This is true for many of the 41 insect-pollinated plant species growing in a Phrygana scrubland habitat on the Greek island of Lesbos. […]

  • Fly away home? Ice age may have clipped bird migration
    on September 20, 2017 at 6:46 pm

    The onset of the last ice age may have forced some bird species to abandon their northerly migrations for thousands of years, says new research led by an ornithologist. The study challenges a long-held presumption that birds merely shortened their migratory flights when glaciers advanced south to cover much of North America and northern Europe about 21,000 years ago. […]
