Nature, Published online: 27 November 2020; doi:10.1038/d41586-020-03368-0 As COVID-19 restrictions continue to upend plans for data collection, scientists stuck at home are finding innovative ways to adapt their research questions. Here's what they're doing.
The coronavirus is not a shape shifter like the flu virus, but it could become vaccine resistant over time. That prompts researchers to urge vigilance.
To control the virus, some officials are forgoing rules or mandates and instead are relying on individuals to do the right thing. So what motivates behavior change, and what falls short?
Kronisk obstruktiv lungsjukdom, kol, beräknas orsaka omkring 3 000 förtida dödsfall varje år i Sverige. Den största riskfaktorn för att drabbas är tobaksrökning, och ungefär 80 procent av de som drabbas är rökare. Men även exponering för partiklar i luften kan öka risken, exempelvis på arbetsplatsen, eller vid matlagning över öppen eld som är vanligt i låginkomstländer.

Hello, I have to validate some some affective images for further event-related potential studies. I will show my participants (around n=20) and record EEG. In addition that, I will ask self-report for each picture for its valence and arousal. Would it be possible? How can I do that? I could not find any paper for validation of affective images by using EEG. If you have any, could you please tell
An endless flow of information is coming at us constantly: It might be an article a friend shared on Facebook with a sensational headline or wrong information about the spread of the coronavirus. It could even be a call from a relative wanting to talk about a political issue. All this information may leave many of us feeling as though we have no energy to engage. As a philosopher who studies know
A UCLA study publishing Nov. 27 in Science supports a new conservation strategy. Climate change increasingly makes relocating threatened species necessary, despite the frequently low success rate. The study found tortoises with lots of genetic variation were much more likely to survive after their relocation. The research supports this fast, inexpensive conservation tool, and upends the convention
Research published in Science reveals how pores form during metals additive manufacturing and become defects trapped in solidifying metal. The practical value of this research is that it can inform industry on how to predict and improve 3D printing processes.
New research has identified and described a cellular process that, despite what textbooks say, has remained elusive to scientists until now — precisely how the copying of genetic material that, once started, is properly turned off.
Legal scholars, computer scientists and economists must work together to prevent unlawful price-surging behaviors from artificial intelligence (AI) algorithms used by rivals in a competitive market, argue Emilio Calvano and colleagues in this Policy Forum.
Tortoise refugees with the highest genetic variation are far more likely to survive conservation translocation than tortoises whose genetic diversity is lower, according to a new study.
The abrupt shift to hotter and drier conditions over inner East Asia is unprecedented and may herald an irreversible shift to a new climate regime for the region, according to a new study.
Finding medicines that can kill cancer cells while leaving normal tissue unscathed is a Holy Grail of oncology research. In two new papers, scientists at UC San Francisco and Princeton University present complementary strategies to crack this problem with 'smart' cell therapies — living medicines that remain inert unless triggered by combinations of proteins that only ever appear together in canc
Researchers warn that heatwaves and concurrent droughts of Mongolia's semi-arid plateau have increased significantly during the past two decades, with troubling implications for the future. The change also has ramifications for atmospheric conditions across the Northern Hemisphere.
