While the world focuses on controlling global warming caused by CO2 emissions from fossil fuels, less attention has been paid to the capacity of vegetation and soils to take up and store carbon. A remote field site in the Norwegian mountains is improving our understanding of carbon cycling in high-latitude alpine areas.
Mussels protect themselves against environmental disturbances and enemies through a hard, calcareous shell. Increased ocean acidification makes it difficult for organisms to form their shells. In a study published today, in the international journal, Nature Communications, a group of scientists from the Kiel University and GEOMAR Helmholtz Centre for Ocean Research Kiel show that mussel larvae react sensitively to ocean acidification, which leads to reduced calcification rates and shell dissolution.
Alzheimer's disease is caused by tangles in the brain made up of malfunctioning aggregated Tau proteins. Scientists at EPFL have discovered a new toxic form of Tau that forms as a result of its interaction with cell membranes. The research is published in Nature Communications and provides novel insights into possible mechanisms by which this protein moves in the brain and kills neurons.
Cataglyphis fortis desert ants can learn visual or olfactory cues to pinpoint their nest, but only if these cues are unique to specify the nest entrance. Scientists from the Max Planck Institute for Chemical Ecology in Jena, Germany, discovered that the insects ignore visual landmarks or odors as nest-defining cues, if these occur not only near the nest but also along the route. Hence, ants are able to evaluate the informative value of such cues.
Camponotini ant species have their own distinct microbiomes and the bacteria may also vary by developmental stage, according to a study published Nov. 22, 2017, in the open-access journal PLOS ONE by Manuela Oliveira Ramalho from the Universidade Estadual Paulista 'Júlio de Mesquita Filho,' Brazil, and colleagues.
Playing a video game that rewards participants for holding various "ninja" poses could help children and youth with autism spectrum disorder (ASD) improve their balance, according to a recent study in the Journal of Autism and Developmental Disorders led by researchers at the University of Wisconsin-Madison.
UCLA researchers report that they have developed new uses for deep learning: reconstructing a hologram to form a microscopic image of an object and improving optical microscopy. Their new holographic imaging technique produces better images than current methods that use multiple holograms, and it's easier to implement because it requires fewer measurements and performs computations faster.
A new simple test that helps predicts which people with type 2 diabetes will benefit most from weight loss surgery has been developed by a UCL-led team.
A cheap and widely used drug, used to treat conditions such as heartburn, gastritis and ulcers, could work against the bacteria that cause tuberculosis (TB), according to new research published in PLOS Medicine, from UCL and the London School of Hygiene & Tropical Medicine.
A diabetes drug currently undergoing development could be repurposed to help end transplant rejection, without the side-effects of current immunosuppressive drugs, according to new research by Queen Mary University of London.
