  • Tiny fossils reveal backstory of the most mysterious amphibian alive
    on June 19, 2017 at 7:15 pm

    The fossils of an extinct species from the Triassic Period are the long-missing link that connects Kermit the Frog's amphibian brethren to wormlike creatures with a backbone and two rows of sharp teeth, new research shows. Named Chinlestegophis jenkinsi, the newfound fossil is the oldest relative of the most mysterious group of amphibians: caecilians. Today, these limbless, colorful serpentine carnivores live underground and range in size from 6 inches to 5 feet. […]

  • Volcanic eruptions triggered dawn of the dinosaurs
    on June 19, 2017 at 7:15 pm

    Huge pulses of volcanic activity are likely to have played a key role in triggering the end Triassic mass extinction, which set the scene for the rise and age of the dinosaurs, new research has found. […]

  • Spineless creature studied in DC swamp
    on June 19, 2017 at 2:18 pm

    Its name is Stygobromus hayi, the Hay's Spring amphipod. It is spineless. It lacks vision. It is an opportunistic feeder, consuming whatever resources are available -- perhaps including the remains of its own kind. That is where its similarities to some of Washington, D.C.'s more notorious megafauna end. Researchers report on a way to survey it without threatening its existence, as other studies had done. […]

  • Red and eastern wolves are probably not recent hybrids
    on June 8, 2017 at 2:24 am

    A research team is calling into question a 2016 study that concluded eastern and red wolves are not distinct species, but rather recent hybrids of gray wolves and coyotes. In a new comment paper, the team argues the study's genomic data and analyses do not definitively prove recent hybridization -- but rather provide support for the genetic and evolutionary distinctiveness of red and eastern wolves. […]

  • Finding new homes won't help emperor penguins cope with climate change
    on June 7, 2017 at 7:12 pm

    Unlike other species that migrate successfully to escape the wrath of climate change, a new study shows that dispersal may help sustain global Emperor penguin populations for a limited time, but, as sea ice conditions continue to deteriorate, the 54 colonies that exist today will face devastating declines by the end of this century. […]

  • Seeing inside coral
    on June 7, 2017 at 5:32 pm

    New technologies are making it possible to see inside coral, to examine the skeleton cores for devastation caused by humans. Scientists are racing the clock to assess the true extent of the damage before it becomes irreversible. […]

  • Which extinct ducks could fly?
    on June 7, 2017 at 12:55 pm

    We're all familiar with flightless birds: ostriches, emus, penguins -- and ducks? Ducks and geese have been especially prone to becoming flightless over the course of evolutionary history, but it can be difficult to determine from fossils whether an extinct species could fly or not. A new study takes a fresh approach, classifying species as flightless or not based on their skeletons and offering a glimpse into the lives of these extinct waterfowl. […]

  • How can you tell deep-sea octopuses apart? Check their warts
    on June 7, 2017 at 12:55 pm

    Until now, there'd been no rigorous framework for telling apart two species of deep-sea octopuses -- they're both pink and warty. A new study, though, shows that the distribution of warts is an important means of telling the two species apart -- the octopuses from the Pacific are wartier than the ones from the Atlantic. That little piece of information could be a big help in ongoing deep-sea research. […]

  • Genetic study shakes up the elephant family tree
    on June 6, 2017 at 3:28 pm

    New research reveals that a species of giant elephant that lived 1.5 million to 100,000 years ago -- ranging across Eurasia before it went extinct -- is more closely related to today's African forest elephant than the forest elephant is to its nearest living relative, the African savanna elephant. Understanding elephant evolution is key to protecting present-day elephants from extinction, researchers say. […]

  • Could acidifying oceans slow down coral disease?
    on June 5, 2017 at 5:37 pm

    Black band disease is less deadly to mountainous star coral (Orbicella faveolata) as water acidified, or decreased in pH, a new study has demonstrated. […]

  • Census shows which mammals survive in forests surrounded by sugarcane plantations
    on June 5, 2017 at 1:22 pm

    A census of medium and large mammals found in 22 forest remnants surrounded by sugarcane plantations in the state. They found approximately 90% of all the species of mammals expected for São Paulo State but in smaller forest fragments, the researchers recorded only 20 percent - 50 percent of the species expected to occur across the region. This means that up to 80 percent were locally extinct in some cases. […]

  • Red light has no effect on bat activity: Less disruption by changing artificial color
    on June 2, 2017 at 3:28 pm

    Artificial light at night can have a disruptive effect on bats, but not if the light is red. Switching to red light may therefore limit or prevent habitat loss for rare, light-shy bat species, report scientists. […]
