  • NASA images reveal disappearing mangroves worldwide

    In August NASA and the US Geological Survey released the first-ever satellite analysis of the world’s mangrove ecosystems. What they found was dire: mangroves covered 12.3% less area than previously estimated.

  • Hairy enigma of the Serengeti photographed again

    A mysterious—and extremely hairy—animal has been photographed again in the Serengeti. Robert Berntsen, a frequent traveler to East Africa, photographed the creature, almost certainly a gazelle, in Kenya’s Masai Mara Reserve. It was earlier photographed by Paolo Torchio in the same reserve.

  • Unprecedented tundra fire likely linked to climate change

    A thousand square kilometers of the Alaskan tundra burned in September 2007, a single fire that doubled the area burned in the region since 1950. However, a new study in the Journal of Geophysical Research finds that the fire was even more unprecedented than imagined: sediment cores found that it was the most destructive fire…

  • Amazon biodiversity older than believed

    A new study in Science has found that the incredible biodiversity of the Amazon rainforest goes back much further than expected, perhaps upending old ideas about how the Amazon basin became arguably the world’s most biodiverse ecosystem. According to the study, the origin of rich biodiversity in the Amazon likely goes back more than 20…

  • Biological shocker: snake reproduces asexually

    Researchers have discovered a biological shocker: female boa constrictors are capable of giving birth asexually. But the surprise doesn’t end there. The study in Biology Letters found that boa babies produced through this asexual reproduction—also known as parthenogenesis—sport a chromosomal oddity that researchers thought was impossible in reptiles.

  • Tropical agriculture “double-whammy”: high emissions, low yields

    Food produced in the tropics comes with high carbon emissions and low crop yields, according to a new study in the Proceedings of the National Academy of Sciences (PNAS). In the most comprehensive and detailed study to date looking at carbon emissions versus crop yields, researchers found that food produced in the tropics releases almost…

  • Picture: new monkey discovered in Myanmar

    Hunters’ reports have led scientists to discover a new species of monkey in the northern forests of Myanmar. Discovered by biologists from the Myanmar Biodiversity and Nature Conservation Association with support from primatologists with Fauna & Flora International (FFI) and the People Resources and Biodiversity Foundation, the strange looking primate is a member of the…

  • Space tourism will worsen climate change

    Have $200,000 to spend on a seat into space? You may want to re-think the expenditure given a new study in Geophysical Research Letters that shows space tourism will likely aggravate global climate change. Using sophisticated modeling, the researchers found that the biggest impact of a rise in space tourism on global temperatures won’t be…

  • Island nation announces Mongolia-sized sanctuary for whales and dolphins

    Dolphins, whales, and dugongs will be safe from hunting in the waters surrounding the Pacific nation of Palau. At the Convention on Biological Diversity (CBD) in Nagoya, Japan, Palau’s Minister of the Environment, Natural Resources and Tourism, Harry Fritz, announced the establishment of a marine mammal sanctuary covering over 230,000 square miles (60,000 square kilometers)…

  • Obama science advisor wields evidence to undercut climate change deniers

    US President Barack Obama’s science advisor, John Holdren, took on climate change deniers in a comprehensive, data-heavy speech last month at the Kavli Science Forum in Oslo, Norway. Proclaiming that “the earth is getting hotter”, Holden went on to enumerate on the causes of climate change (human impacts) and its overall effect (not good), discussing…
