Cement can be reused by including it as a component of steel recycling. This opens the way to an industrial partnership that improves the use of materials and lowers carbon emissions — but only if waste resources are well managed.
Neuroscientists find that two distinct neural pathways are responsible for the addictive properties of the opioid fentanyl: one mediates reward, the other promotes the seeking of relief from symptoms of withdrawal.
A phenomenon that affects the magnetic fields of rotating bodies could be involved in recurring changes in the Sun’s behaviour, which are related to a periodic flipping of its field. The proposal is a fresh take on this strange effect.
A simple design approach and predictive computational methods have spawned a pathway for making materials that could trap specific molecules — an ability needed for applications such as carbon capture.
Artificial neural networks that model the visual system of a male fruit fly can accurately predict the insect’s behaviour in response to seeing a potential mate — paving the way for the building of more complex models of brain circuits.
The chemistry of promethium, a rare radioactive element, has been clouded in mystery, owing to its scarcity and the difficulties involved in working with it. The synthesis of a complex of promethium plugs this knowledge gap.
When chromosomes are lost or gained, massive changes in gene expression disrupt the delicate balance of proteins in a cell. Yeasts with incorrect chromosome numbers counteract this by degrading excess proteins.
Long-term memories are thought to be represented by the same brain areas as those that encode sensory stimuli, but the mechanisms remain unclear. A study that recorded neural activity from face-selective regions of the macaque brain found that these regions represent familiar faces using a neural code that is distinct from the one for sensory representation.
ChatGLM is one of hundreds of AI language models being developed for the Chinese language. It comes close to ChatGPT on many measures, say its creators.
For 100 years, Egypt’s scientists have watched as their nation’s story was largely told by institutions from Europe and the United States. Can a stunning new museum change that narrative?
