Researchers have provided a detailed description of the stunning array of fungi that make their home on the Polynesian island of Mo'orea. The collection includes more than 200 species of macrofungi -- that is, fungi producing visible, fruiting bodies -- many of which may be new to science.
Burst of accumulated zinc shows how the mineral boosts immune function, suggesting ways to improve health
Zinc's immune-boosting properties are well-established, but scientists haven't known exactly how it works. Scientists now reveal two ways the mineral supports immunity and suggest how it could be used to improve health. Using mice, the team discovered that zinc is needed for the development of disease-fighting immune cells called T...
New technology solves mystery of respiration in Tetrahymena
Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration -- using oxygen to generate cellular energy -- differently from other organisms such as plants, animals or yeasts. The discovery highlights the power of new techniques in structural biology and reveals gaps in our...
German and Austrian deer thus far spared SARS-CoV-2 infections, unlike in North America
In North America, SARS-CoV-2 has spread from humans to white-tailed deer. The deer are now considered SARS-CoV-2 reservoirs and may even spill virus back to humans. Scientists have now shown that in Germany and Austria this has not happened as all deer tested were negative for SARS-CoV-2 antibodies.
Scientists bioprint tissue-like constructs capable of controlled, complex shape change
New cell-laden bioink, comprised of tightly-packed, flake-shaped microgels and living cells, the production of cell-rich 4D bioconstructs that can change shape under physiological conditions.
A scaffold with a twist: Cryo-EM reveals the building blocks of poxvirus
Researchers have revealed how poxviruses build their scaffold - a temporary protein coat that forms and disappears as the virus matures.
African network protects key turtle sites
A network of West African Marine Protected Areas (MPAs) covers key sites used by green turtles, new research shows.
How is haze formed?
Haze is formed when a cocktail of various gaseous pollutants is oxidized and forms particulate matter diffusing sunlight. This process is mainly mediated by hydroxyl radicals (OH), and researchers have now discovered a new route to their formation. This newly discovered radical-building mechanism could also offer new perspectives for air...
Babies exposed to cannabis in the womb may be at risk for obesity, high blood sugar
Cannabis use among pregnant women is on the rise and may be associated with negative health outcomes in children, according to a new study.
Critical signature sound when rocks crack
Finding the specific sound a rock makes when it cracks and breaks seems impossible when surrounded by other subsurface noises. But researchers have now discovered a way to hear and validate that sound.
