| James Webb Space Telescope’s latest selfie marks a milestone for the space observatory Posted: 16 Mar 2022 04:48 PM PDT  New images from the James Webb Space Telescope show the latest big milestone for the space observatory: its 18 mirrors are now aligned enough to act as one massive mirror. The new images released by NASA today include a "selfie" from JWST showing the mirrors' progress along with updated images of a single star. Since reaching its final orbit, the telescope's combined 18 mirrors have been focused on the isolated star HD 84406, which the researchers are using as a target to align the mirrors. Images presented last month showed 18 images of the star that were captured individually on each mirror segment. NASA's latest image of HD 84406 shows what it looks like when all 18 mirrors work together with the Near-Infrared Camera or NIRCam. They... |
| Storms and sea level rise could cost ports billions Posted: 16 Mar 2022 11:12 AM PDT  Ports around the world stand to suffer billions of dollars in losses if greenhouse gas emissions continue to grow, a new report finds. Extreme weather, flooding, and rising sea levels would all damage vital seaport infrastructure, disrupting global supply lines. Losses from storms and climate-related port disruptions could near $10 billion a year by 2050, according to the report, commissioned by the nonprofit Environmental Defense Fund (EDF). By 2100, without action on climate change, those costs could balloon to more than $25 billion a year. For context, that last figure is more than the total operating profits for the entire global container shipping industry in a year. Many ports are already overwhelmed after the COVID-19 pandemic... |
| Keywords from hallucinogenic experiences can help find parts of the brain affected by drugs Posted: 16 Mar 2022 11:00 AM PDT  People have vast, spiraling experiences on psychedelic drugs, often returning from a hallucinogenic trip full of new outlooks on their life or even changes to their personality. They describe the trips with vivid, emotional language — which might be able to tell researchers what parts of their brains are reacting to the drugs. In order to figure out how and why hallucinogenics trigger certain experiences, a research team used machine learning to pull common words and phrases out of people's testimonials about their trips. Then, in a new study published Wednesday, the researchers linked those words to the parts of the brain impacted by the drugs. It's a different approach to studying drugs and the brain: normally, researchers looking to... |
| Astra successfully returns to flight just a month after launch failure Posted: 15 Mar 2022 11:14 AM PDT  Space startup Astra successfully returned to launch today, a little more than a month after its last launch failed mid-flight. Taking off from Kodiak, Alaska, Astra's LV0009 rocket deployed the satellites it was carrying into orbit for three commercial companies, marking the company's first successful commercial mission. There was a brief moment during the flight, however, where it seemed like today's mission might have been a failure. Soon after reaching orbit, the vehicle was supposed to deploy the satellites it was carrying (except for one that was to remain attached to the rocket). However, Astra did not immediately receive confirmation that the payloads had deployed and ended its livestream of the flight before getting word about... |
