  • As the fate of the Great Barrier Reef remains uncertain, a new study has examined the health of the reef over the last 30,000 years, and found that it has suffered five “death events” in the past – but its current woes could be the last straw.
  • Our universe seems to contain a suspiciously perfect amount of "dark energy" to sustain life. But new research suggests that life is still possible even with far more dark energy than we have, and the results have some big implications for the multiverse theory.
  • An international team of astronomers has released survey data detailing the chemical fingerprints of over 340,000 stars. The observations could be used to identify stellar bodies that formed alongside our Sun billions of years ago.

    ​If ships' hulls are covered in barnacles and other marine organisms, then those ships have to work harder, burn more fuel, and create more CO2 emissions in order to move through the water. That's why scientists have created a plant-inspired coating that keeps the critters from getting a foothold.

    ​​Our planet is expected to host an extra two billion people by 2050, making food security a real issue. Researchers are now reporting an advance in a field known as speed breeding, which relies on intense lighting regimes to raise crops several times faster.
  • ​​Advanced surgical glues that seal wounds faster could mean big things when it comes to medical care. A new material is showing particular promise in this regard, with the ability to be squirted directly into a wound, seal it in 60 seconds and dissolve thereafter. ​
  • Zinc-air batteries are enticing thanks to their high energy density and cheap materials. Unfortunately, that's countered by how difficult it is to recharge them. Now researchers have created new catalysts out of abundant elements that could see rechargeable zinc-air batteries vying with li-ions.
  • How did the ancestors of the cathedral termites, architects of some of the most remarkable structures in the animal kingdom, arrive in Australia and adapt to their new environment? You can attribute it to two things: An incredible will to survive and a lot of luck.

    People have been fascinated by dolphins for millennia, but we still know very little about their life in the wild. Now a team of scientists has developed cameras that harmlessly attach to the animal and provide a unique account of dolphin behavior beneath the waves.
  • ​A team of scientists mapping the seafloor along Australia's Great Barrier Reef have stumbled upon the remains of a huge underwater landslide. Its estimated 32 km cubed volume is around 30 times that of Uluru, the giant red rock in Australia's center.
  • Researchers have recently blasted through another quantum quandary, potentially bringing stability to the notoriously unstable world that exists in these computing systems. New Atlas spoke with one of the researchers to get more information about the potentially game-changing work.
  • Science
    A thumbnail-sized fragment of a stone axe found in a remote area of Western Australia predates previous discoveries by more than 10,000 years. The axe fragment is estimated to be between 45,000 and 49,000 years old and was invented soon after humans arrived in Australia around 50,000 years ago.
