Discovery reveals a reversible magnetic field around a fast radio burst for the first time
快速射电暴 可逆磁场 无线电波闪光
2023/5/15
An international team of researchers has revealed new evidence on the nature of mysterious fast radio bursts (FRBs) – objects in space that produce brief, intense flashes of radio waves from distant g...
A new algorithm helps drones find the fastest route around obstacles without crashing. The system could enable fast, nimble drones for time-critical operations such as search and rescue.
Drug-resistant bacteria found in the guts of lemurs who live around humans The more human interaction they had, the higher the proportion of resistant bugs
antibiotics resistance lemur gut microbiota
2021/8/10
Researchers have found evidence for antibiotic resistance in the gut microbiomes of lemurs living close to humans. The more human contact they have, the more antibiotic resistance there is. Even capti...
Overfishing and other human pressures are severely harming many marine protected areas around the world, study finds
ecological destruction edge effect marine conservation areas MPA
2021/8/11
A new study points to a strong 'edge effect' in marine protected areas (MPAs), sharply reducing by 60 percent the fish population living up to 1 - 1.5 km within the MPA. This significantly diminishes ...
