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.
How nerve and vascular cells coordinate their growth
Nerve cells need a lot of energy and oxygen. They receive both through the blood. This is why nerve tissue is usually crisscrossed by a large number of blood vessels. But what prevents neurons and vascular cells from getting in each other's way as they grow? Researchers have identified a...
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.
Using deep learning to monitor India’s disappearing forest cover
Using satellite monitoring data, researchers have developed a deep learning algorithm that could provide real-time monthly land use and land cover maps for parts of India.
