Event horizon telescope captures the highest-resolution black hole images from Earth
The Event Horizon Telescope (EHT) collaboration has achieved the highest resolution observations ever from Earth by detecting light at 345 GHz from the centers of distant galaxies. This higher frequency allows for sharper images and insights into black holes and their environments. By using very long baseline interferometry (VLBI) across multiple telescopes, the EHT creates […]
Zinc-air battery powers breakthrough in green hydrogen production
Researchers at KAIST in South Korea developed a new hydrogen production system that uses a zinc-air battery to power the process, reducing fire risks. Currently, green hydrogen produced via water electrolysis with renewable energy has efficiency issues due to fluctuations in sources like solar and wind. Air batteries can be used instead but require expensive […]
This Skeleton Is The First Person Ever Found From a Norse Saga
– Scientists have analyzed the bones of a man found in a well at Sverresborg Castle in Norway from 1938. – This fits with a passage from the 800-year-old Norse saga Sverris Saga, which describes invaders throwing a dead body into the castle well. – DNA analysis found the bones belong to a man aged […]
Brain Scans Show Neuron Structures Look Different in Kids With Autism
– Researchers used advanced MRI techniques to examine the brain structures of 142 autistic children and compare them to 8,971 non-autistic children. – The scans revealed differences in neuron densities in parts of the cerebral cortex involved in learning, reasoning, problem-solving and memory formation. Specifically, lower densities were found. – Higher neuron densities were detected […]
Hyundai unveils world’s first hydrogen-powered, silent stealth battle tank
– South Korean company Hyundai has unveiled plans for the world’s first hydrogen-powered battle tank, called the K3. – The next version of South Korea’s K-series battle tanks will utilize hydrogen fuel cells instead of diesel engines to power the tank. This will make it the first hydrogen military vehicle. – Prototypes are currently hybrid […]
Researchers use magnetic fields to freeze light in its tracks
Researchers from AMOLF and Delft University of Technology have demonstrated a new technique to stop light waves using magnetic fields at the nanoscale. They deformed a two-dimensional photonic crystal, which is an array of tiny holes in silicon that light can pass through. By precisely disrupting the regular pattern of the crystal, they were able […]
SpaceX’s Crew-8 Returns NASA Astronauts To Earth After 7 Months
SpaceX’s Crew Dragon spacecraft splashed down off the coast of Florida on October 25th, returning 4 astronauts from the International Space Station after a 7 month mission. The astronauts included NASA’s Matthew Dominick, Michael Barratt and Jeanette Epps, as well as Alexander Grebenkin from Roscosmos, Russia’s space agency. They had launched aboard the Crew Dragon […]
AI helps humans have a 20-minute conversation with a whale
Scientists from the University of California Davis and the SETI Institute had a 20-minute interaction with a humpback whale named Twain off the coast of Alaska. Using an underwater speaker, the researchers played recorded humpback contact calls. To their surprise, Twain approached and started responding by circling them and matching the timing of the calls. […]
Recycled wind turbines may one day become tiny homes and floating playgrounds
Dutch companies Vattenfall and Superuse showcased a tiny home built inside the hollowed-out nacelle (casing) of a decommissioned wind turbine. The 393 sq ft home includes a living space, bathroom and solar-powered amenities. Recycling wind turbine components is challenging as they often end up in landfills. This project shows one way to reuse major turbine […]
China builds the world’s most powerful magnet
– Scientists in China have built the world’s most powerful magnet capable of generating a magnetic field 800,000 times stronger than Earth’s. – The magnet produced a steady magnetic field of 42.02 tesla, breaking the previous record of 41.4 tesla set by US researchers in 2017. – It required 4 years of development and could […]
