  • Water, not temperature, limits global forest growth as climate warms
    on January 16, 2019 at 8:06 pm

    The growth of forest trees all over the world is becoming more water-limited as the climate warms. The effect is most evident in northern climates and at high altitudes where the primary limitation on tree growth had been cold temperatures. The research details the first time that changes in tree growth in response to current climate changes have been mapped at a near-global scale. […]

    More than three-quarters of marine mammal and sea turtle populations have significantly increased after listing of the US Endangered Species Act (ESA), according to a new study. […]

  • Researchers rescue photoreceptors, prevent blindness in animal models of age-related macular degeneration
    on January 16, 2019 at 7:06 pm

    Using a novel patient-specific stem cell-based therapy, researchers prevented blindness in animal models of geographic atrophy, the advanced 'dry' form of age-related macular degeneration (AMD), which is a leading cause of vision loss among people age 65 and older. The protocols established by the animal study set the stage for a first-in-human clinical trial testing the therapy in people with geographic atrophy, for which there is currently no treatment. […]

  • Experimental treatment approach shows potential against Staphylococcus aureus
    on January 16, 2019 at 7:06 pm

    A new class of engineered proteins may counter infection caused by Staphylococcus aureus -- a bacterial species considered one of the largest global health threats, a new study suggests. […]

  • New yeast model of metabolic disorders may lead to life-saving therapies
    on January 16, 2019 at 5:26 pm

    A new study suggests that the role of yeast, the world's most basic eukaryotic unicellular organism, may pave the way for the development of novel, more effective therapies for congenital diseases. […]

  • Urbanization may hold key to tiger survival
    on January 16, 2019 at 4:55 pm

    A new study says the future of tigers in Asia is linked to the path of demographic transition -- for humans. […]

  • Engineered light to improve health, food
    on January 16, 2019 at 4:55 pm

    intentionally controlled light can help regulate human health and productivity by eliciting various hormonal responses. Tailored LED wavelengths and intensities also can efficiently stimulate plant growth, alter their shapes and increase their nutritional value, opening a new world of scientific and technological possibilities for indoor farming. […]

  • Vampire bat venom could hold key to new medical treatments
    on January 16, 2019 at 4:11 pm

    Vampire bats could hold the key to new treatments for a range of serious medical problems, but researchers have hit a snag accessing the specimens needed to advance their work. Now scientists have found a new class of blood pressure-regulating peptides in the venom of the common vampire bat (Diphylla ecaudata). […]

  • Jellyfish map could be the future to protecting UK waters and fish
    on January 16, 2019 at 4:10 pm

    Researchers have developed a map of chemicals found in jellyfish caught across 1 million square kilometers of UK waters. The same chemicals are found in other marine animals such as birds and fish. These findings can support conservation efforts by helping track an animals movements and also be used as a tool to detect food fraud by identifying where seafood products were sourced from. […]

  • Coralline red algae have existed for 300 million years longer than presumed
    on January 16, 2019 at 4:10 pm

    Coralline red algae have existed for 130 million years, in other words since the Cretaceous Period, the time of the dinosaurs. At least this was the established view of palaeontologists all over the world until now. However, this classification will now have to be revised after fossils prove that coralline red algae existed as far back as 430 million years ago. […]

  • Simple rules predict and explain biological mutualism
    on January 16, 2019 at 4:09 pm

    Scientists have long employed relatively simple guidelines to help explain the physical world, from Newton's second law of motion to the laws of thermodynamics. Biomedical engineers have used dynamic modeling and machine learning to construct similarly simple rules for complex biology. They have devised a framework to accurately interpret and predict the behavior of mutually beneficial biological systems, such as human gut bacteria, plants and pollinators, or algae and corals. […]

  • Dry-cured ham bones -- a source of heart-healthy peptides?
    on January 16, 2019 at 2:07 pm

    Drinking bone broth is a recent diet fad that proponents claim fights inflammation, eases joint pain and promotes gut health. Simmering animal bones in water releases collagen and other proteins into the broth that may have health benefits, although more research is needed to validate these claims. Now, a new study has shown that ham bones contain peptides that could have cardioprotective effects. […]

  • Following heart health guidelines also reduces diabetes risk
    on January 16, 2019 at 2:07 pm

    You've probably heard that things like staying active, eating healthy and keeping your blood pressure in check can help your heart, and a new study finds that following a set of seven lifestyle factors can also drastically reduce your risk of developing diabetes. […]

  • Ocean giant gets a health check: Combination blood, tissue test reveals whale shark diets
    on January 16, 2019 at 2:06 pm

    Whale sharks, the world's largest fish, likely endure periods of starvation and may eat more plants than previously thought, according to the first results of a new health check. Ocean scientists now have a powerful, simple tool to discover the diets, migrations, and conservation needs of this endangered species. […]

  • Born to run: Just not on cocaine
    on January 16, 2019 at 2:06 pm

    A study finds a surprising response to cocaine in a novel strain of mutant mice -- they failed to show hyperactivity seen in normal mice when given cocaine and didn't run around. In other tests, they still found cocaine appealing, but displayed an inability to shake the memory of cocaine's actions when the drug was no longer administered. The key change that blocks cocaine's stimulant effects in these mice is serotonin, not dopamine, which is responsible for producing a high. […]
