Microraptor was an opportunistic predator, feeding on fish, birds, lizards -- and now small mammals. The discovery of a rare fossil reveals the creature was a generalist carnivore in the ancient ecosystem of dinosaurs.
Using Drones to Monitor Volcanoes: Researchers Analyze Volcanic Gases With the Help of Ultra-Lightweight Sensor Systems
Composition of gases emitted by volcanoes can provide information on the possibility of imminent eruptions / Lightweight drones make investigation possible even in areas that are difficult to access.
Carbon Dioxide Pollution Dropped on California Freeways During Pandemic
The COVID-19 pandemic changed the world, including how people used their cars.
Ammonium is the secret ingredient in stable, efficient, scalable perovskite solar cells
A new pathway to creating durable, efficient perovskite photovoltaics at industrial scale has been demonstrated through the first effective use of lead acetate as a precursor in making formamidinium-caesium perovskite solar cells.
Potentially deadly infection has dangerous ally lurking in our guts
New research reveals how microorganisms in our guts can worsen dangerous C. difficile infections. The discovery could help doctors identify patients at risk for severe illness and open the door to new treatments.
Ants shed light to predicting evolution after hybridization
Researchers found that after multiple hybridization events between two wood ant species distinct hybrid populations evolved independently towards the same direction, suggesting hybridization is predictable.
Easy way to spin nanofibers, inspired by silkworms
Did you know that silk fabric is made from ... well, worm spit? The way that silkworms wind their cocoons from fibers in their slimy saliva is now helping scientists more easily make new biomedical materials. Researchers have mimicked the seemingly simple head bobbing of silkworms to create more consistent...
Decoding the secret language of photosynthesis
For decades, scientists have been stumped by the signals plants send themselves to initiate photosynthesis, the process of turning sunlight into sugars. Researchers have now decoded those previously opaque signals.
Carbon dioxide removal should receive additional financial support, experts urge
Cleaning up greenhouse gases after they have been emitted should be incentivized by subsidies. New evidence from an economic analysis considering international markets suggests an important reason why subsidies should be higher than the price put on carbon emissions to incentivize their reduction. Researchers analyze policies for removing carbon dioxide...
Biodegradable medical gowns produce harmful emissions
Biodegradable medical gowns, designed to be greener than conventional counterparts, actually produce harmful greenhouse gases, according to new research.
