  • Trees can make or break city weather
    on July 26, 2017 at 1:15 pm

    Even a single urban tree can help moderate wind speeds and keep pedestrians comfortable as they walk down the street, according to a new study that also found losing a single tree can increase wind pressure on nearby buildings and drive up heating costs. […]

  • Evolutionary biologists solve puzzle of evolutionary relationships among vertebrates
    on July 24, 2017 at 5:31 pm

    Using the largest and most informative molecular phylogenetic dataset ever analysed, evolutionary biologists were able to construct a new phylogenetic tree of jawed vertebrates. This new tree resolves several key relationships that have remained controversial, including the identification of lungfishes as the closest living relatives of land vertebrates. The evolution of jawed vertebrates is part of our own history since humans belong to the tetrapods more specifically we are mammals, or, even more specifically, primates. […]

  • Paying people to protect forests is worth it
    on July 20, 2017 at 6:23 pm

    A new study suggests that paying people to conserve their trees could be a highly cost-effective way to reduce deforestation and carbon emissions and should be a key part of the global strategy to fight climate change. The study sought to evaluate how effective 'Payments for Ecosystems' (PES) is at reducing deforestation. […]

  • Gene drives likely to be foiled by rapid rise of resistance
    on July 20, 2017 at 6:22 pm

    A study in fruit flies suggests that existing approaches to gene drives using CRISPR/Cas9, which aim to spread new genes within a natural population, will be derailed by the development of mutations that give resistance to the drive. […]

  • Bornean orangutans' canopy movements flag conservation targets
    on July 18, 2017 at 4:47 pm

    Bornean orangutans living in forests impacted by human commerce seek areas of denser canopy enclosure, taller trees, and sections with trees of uniform height, according to new research. These orangutans are critically endangered, and despite intense conservation efforts, their numbers continue to decline. Additional habitat management strategies that account for their presence in forests affected by logging and other human activity are needed to ensure the species' survival. […]

  • Nesting in cavities protects birds from predators, to a point
    on July 12, 2017 at 11:28 am

    Nesting in cavities provides birds with some protection from predators -- but it isn't foolproof. A new study explores how Poland's cavity-nesting marsh tits deal with predator attacks and finds that while tactics such as small entrances and solid walls do help, adaptations like this can only take the birds so far. […]

  • 'Star dust' wasp is a new extinct species named after David Bowie's alter ego
    on June 22, 2017 at 2:40 pm

    During her study on fossil insects at China's Capitol Normal University, a student visited the Smithsonian National Museum of Natural History, USA, carrying two unidentified wasp specimens that were exceptionally well-preserved and 100 million years old. Close examination revealed that both were species new to science. Furthermore, one of them was found to belong to a genus of modern wasps. […]

  • Is it sometimes OK to cheat?
    on June 20, 2017 at 1:32 pm

    When both partners benefit from a relationship -- husband and wife or pollinator and flower -- the relationship is known as a mutualism. Sometimes partners do not deliver their side of the bargain while still reaping the rewards. New research shows that unless unfaithful partners are severely punished by the other member of the relationship cheaters may become more common. […]
