Webb lifts veil on common but mysterious type of exoplanet
Though they don’t orbit around our sun, sub-Neptunes are the most common type of exoplanet, or planet outside our solar system, that have been observed in our galaxy. These small, gassy planets are shrouded in mystery…and often, a lot of haze. Now, by observing exoplanet TOI-421 b, NASA’s James Webb Space Telescope is helping scientists understand sub-Neptunes in a way that was not possible prior to the telescope’s launch.
“I had been waiting my entire career for Webb so that we could meaningfully characterize the atmospheres of these smaller planets,” said principal investigator Eliza Kempton of the University of Maryland, College Park. “By studying their atmospheres, we’re getting a better understanding of how sub-Neptunes formed and evolved, and part of that is understanding why they don’t exist in our solar system.”
The findings are published in The Astrophysical Journal Letters.
What time is it on the moon? US House space committee wants a standard lunar clock

First Look at Berkeley Humanoid Lite, an Open-Source, 3D-Printable Humanoid Robot
Berkeley Humanoid Lite is an open-source, budget-friendly humanoid robot created by UC Berkeley researchers to make robotics research easier for everyone. It’s a customizable, 3D-printed robot designed for researchers, teachers, and hobbyists. Unlike expensive, closed-source commercial robots (often over $100,000), it costs less than $5,000 by using common parts and desktop 3D printers. The robot’s motors and body use 3D-printed cycloidal gearboxes, keeping costs low while staying sturdy. You can buy all parts from online stores, and the design works with a 3D printer that has at least a 200 × 200 × 200 mm build space. It’s 80 cm

Designer microbe shows promise for reducing mercury absorption from seafood
An engineered gut microbe can detoxify methylmercury, reducing the amount that passes into the brain and developing fetuses of mice fed a diet rich in fish, UCLA and UC San Diego’s Scripps Institution of Oceanography scientists have discovered.
“We envision the possibility that people could take a probiotic to offset the risk of consuming too much methylmercury, especially when pregnant,” said UCLA associate professor and director of the UCLA Goodman-Luskin Microbiome Center Elaine Hsiao, who is the senior author of a paper describing the research in the journal Cell Host & Microbe.
Mercury is a pollutant that enters water from several sources, the largest of which are human activities such as coal burning, artisanal gold mining and smelting, and wastes from consumer products. In the ocean, mercury transforms into a toxic form called methylmercury. It also biomagnifies, meaning that methylmercury concentrations in animal tissues increase up the food chain from algae-eaters to top predators like humans.
Astronomers Capture Breathtaking Image of Newborn Star Taking Shape
The James Webb Space Telescope (JWST) has been giving us a fabulous new view on the Universe since its launch.
This new image of the protostar HH30 is in amazing new detail thanks to the JWST. It was first discovered using the Hubble Space Telescope, but this Herbig-Haro object, which is a dark molecular cloud, is a perfect object for JWST.
The image shows the protoplanetary disk seen edge on, with a conical outflow of gas and dust, with a narrow jet blasting out into space.
Gravity Isn’t Real? This Theory Says It’s a Simulation
What if gravity isn’t a force, but a computation? In this episode, we explore Dr. Melvin Vopson’s groundbreaking theory that gravity emerges from the universe’s effort to compress and optimize information. Discover how this idea connects with simulation theory, quantum physics, and the future of reality.
