DNA analyses of skeletal fragments from a site in Germany provide evidence that humans, rather than Neanderthals, were responsible for a particular stone-tool industry called the Lincombian–Ranisian–Jerzmanowician.
In a multicellular organism, normal growth requires control of cell division to generate cells that are similar to or different from their parents. Analysis of this process in plant roots reveals how this mechanism is regulated.
Nocturnal insects’ instinct to keep their back to the light makes them appear attracted to lamps. Plus, the emerging field of cancer neuroscience and the cognitive benefits of playing an instrument.
Crystalline silicon solar cells have been brittle, heavy and fragile until now. Highly flexible versions with high power-to-weight ratios and power conversion efficiencies of 26.06–26.81% were produced by improving manufacturing and design technologies and by using thin wafer substrates.
Conservation is bringing back certain predators that are high in the food chain, but how this affects an ecosystem overall is debated. Rigorous fieldwork provides strong evidence that sea otters help to mitigate coastal erosion.
The discovery that an evolutionarily conserved molecule used to make cholesterol also acts as a defence against a cell-death mechanism called ferroptosis might lead to new ways to treat cancer and other clinical conditions.
A neural probe has been used to capture the activity of large populations of single neurons as people are speaking or listening, providing detailed insights into how the brain encodes specific features of speech.
A technique for embedding fibres with semiconductor devices produces defect-free strands that are hundreds of metres long. Garments woven with these threads offer a tantalizing glimpse of the wearable electronics of the future.
Early embryonic development in humans remains poorly understood. A 3D cellular model called bilaminoids, generated using ‘naive’ pluripotent stem cells and derived cell types, successfully recapitulates early development and enables mechanistic studies to examine how various cellular components interact to regulate early embryogenesis.
We investigate the mechanism underlying the sulfur reduction reaction that plays a central role in high-capacity lithium sulfur batteries, highlighting the electrocatalytic approach as a promising strategy for tackling the fundamental challenges associated with these batteries.
A machine learning model for generating crop-specific and spatially explicit NH3 emission factors globally shows that global NH3 emissions in 2018 were lower than previous estimates that did not fully consider fertilizer management practices.
Proferroptotic activity of 7-dehydrocholesterol reductase is shown along with an unexpected prosurvival function of its substrate, 7-dehydrocholesterol, indicating a cell-intrinsic mechanism that could be used by cancer cells to protect phospholipids from oxidative damage and escape ferroptosis.
