Bobbit worms ambush prey from tunnels under the sand. A new study shows their ancestors haunted the ocean floor 20 million years ago.
Dotty graphene and doping: Whatever it takes for Russia’s record plasmonics to shine.
Physicists from MIPT and Vladimir State University, Russia, have achieved a nearly 90% efficiency converting light energy into surface waves on graphene. They relied on a laser-like energy conversion scheme and collective resonances. The paper came out in Laser & Photonics Reviews.
Manipulating light at the nanoscale is a task crucial for being able to create ultracompact devices for optical energy conversion and storage. To localize light on such a small scale, researchers convert optical radiation into so-called surface plasmon-polaritons. These SPPs are oscillations propagating along the interface between two materials with drastically different refractive indices — specifically, a metal and a dielectric or air. Depending on the materials chosen, the degree of surface wave localization varies. It is the strongest for light localized on a material only one atomic layer thick, because such 2D materials have high refractive indices.
Dr. Richi Gill, MD, is back at work, able to enjoy time with his family in the evening and get a good night’s sleep, thanks to research. Three years ago, Gill broke his neck in a boogie board accident while on vacation with his young family. Getting mobile again with the use of a wheelchair is the first thing, Gill says, most people notice. However, for those with a spinal cord injury (SCI), what is happening inside the body also severely affects their quality of life.
“Don’t knock it until you try it” should be for tasting new foods, not building robots capable of ending human life.
Astronomers have found the first Jupiter-like exoplanet with no clouds or haze. It’s an ideal object for further study with the James Webb Space Telescope.
Can you picture Jupiter without any observable clouds or haze? It isn’t easy since Jupiter’s latitudinal cloud bands and its Great Red Spot are iconic visual features in our Solar System. Those features are caused by upswelling and descending gas, mostly ammonia. After Saturn’s rings, Jupiter’s cloud forms are probably the most recognizable feature in the Solar System.
Now astronomers with the Center for Astrophysics | Harvard & Smithsonian (CfA) have found a planet similar in mass to Jupiter, but with a cloud-free atmosphere.

The incredible world first, designed by Urban Air Port, will be located next to the city’s Ricoh Arena and will allow air taxis and electric drones to land and recharge dailystar.
78% respondents said they were comfortable interacting with AI for business-related queries.
Artificial intelligence has come of age. Customers in the country seem to prefer to get responses from a machine than interacting with humans. The reason, according to a survey, answers given by an AI-system is backed with voluminous data that it crunches to deliver right responses.
A study commissioned by Pegasystems, a Nasdaq-listed digital transformation solutions company, has found that 60 per cent of people in the country are more likely to tell the truth to an AI system or chatbot as compared to a human, Suman Reddy, Managing Director of Pega India, told BusinessLine.
