Tech Xplore / Ultrafast nanolasers mimic how the brain imagines unseen parts of the world
A new study has demonstrated how networks of spiking nanolasers could emulate a key principle of brain function: to imagine things that we cannot directly perceive by sampling from internal models of the world. The study, ...
Tech Xplore / OpenAI starts testing ads in ChatGPT
OpenAI has begun placing ads in the basic versions of its ChatGPT chatbot, a bet that users will not mind the interruptions as the company seeks revenue as its costs soar.
Phys.org / Exploring how the immune system detects drugs coated with 'stealth' polymers
A recent study by researchers from Institute of Science Tokyo unveils the molecular mechanisms explaining why some "stealth" drug coatings fail to evade the immune system. Using single-molecule atomic force microscopy, the ...
Phys.org / Scientists harness nature's chirality bias to design series of complex mechanically interlocked molecules
In nature, molecules often show a strong preference for partnering with other molecules that share the same chirality or handedness. A behavior that is quite evident in the phenomenon known as homochirality-driven entanglement, ...
Phys.org / Moving beyond money to measure the true value of Earth science information
They're all around us: sensors and satellites, radars and drones. These tools form vast remote sensing networks that collect data on the climate, the ground, the air, and the water. This information is immensely useful for ...
Phys.org / Satellite record shows boreal forests expanded 12% and shifted north since 1985
The boreal forest—the world's largest terrestrial biome—is warming faster than any other forest type. To understand the changing dynamics of boreal forests, Min Feng and colleagues analyzed the biome from 1985 to 2020, ...
Phys.org / Fruit fly study reveals how mating triggers behavioral changes in females
Researchers from The Universities of Manchester and Birmingham have identified the exact nerve cells in the brain that drive important behavioral changes in female fruit flies after they mate. The discovery, published in ...
Phys.org / Topological antenna could pave the way for 6G networks
Using ideas borrowed from topological photonics, researchers in Singapore, France and the US have designed a compact antenna capable of handling information-rich terahertz (THz) signals. Reporting their results in Nature ...
Medical Xpress / Mindfulness enables more effective endoscopies in awake patients, study finds
A new study has shown that mindfulness helps patients to relax during an endoscopy, allowing doctors to carry out detailed examinations without the need for sedation or general anesthesia.
Phys.org / Half of the world's coral reefs suffered major bleaching during the 2014–2017 global heat wave, estimates suggest
Benefits to society from coral reefs, including fisheries, tourism, coastal protection, pharmaceutical discovery and more, are estimated at about $9.8 trillion per year. For the first time, an international team led by Smithsonian ...
Medical Xpress / How lung tumors use the brain to avoid immune attacks
University of Pennsylvania Perelman School of Medicine and Yale University School of Medicine, along with other collaborators, report that lung adenocarcinoma can engage nerve pathways that link the lung to the brainstem ...
Phys.org / Biofilm made from fish skin could be a sustainable alternative for food packaging
Using the skin of an Amazonian fish known as tambatinga as the raw material, researchers at the University of São Paulo (USP) and EMBRAPA Pecuária Sudeste—a decentralized unit of the Brazilian Agricultural Research Corporation ...
