Star imaged in detail outside the Milky Way for the 1st time
Astronomers have captured the first-ever “zoomed-in” image of a star outside our Milky Way galaxy. The star is called WOH G64 and is located 160,000 light-years away in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. WOH G64 is an extremely large “red supergiant” star, about 2,000 times the size of our […]
Goodbye to outdoor solar panels: This cell works with low-light and indoors
Advancements in solar cell technology are allowing for the collection of energy from indoor and low-light conditions, moving beyond the need for outdoor solar panels. A California-based company called Ambient Photonics has developed low-cost dye-sensitized solar cells (DSSCs) that can operate optimally in areas with minimal direct sunlight, such as indoor lighting conditions. Another innovation […]
US Army taps Raytheon to replace fuel lines with beamed power
The U.S. Army has awarded Raytheon a contract to develop a directed energy wireless power system that can beam energy to where it’s needed on the battlefield. This is part of an effort to simplify military logistics by eliminating the need to move fuel and batteries around. Soldiers today carry large amounts of heavy batteries, […]
Drugs Like Ozempic May Have a Shrinking Effect on The Heart
Popular weight loss drugs like Ozempic and Wegovy have shown promising short-term results, but their long-term side effects remain under investigation. Researchers at the University of Alberta found that semaglutide (the active ingredient in Ozempic) reduced overall heart mass and the size of heart muscle cells in both lean and obese mice, without altering body […]
US achieves 10x nuclear fusion power boost with new ‘fuel mix’ breakthrough
Scientists at the US Department of Energy’s Princeton Plasma Physics Laboratory have made a significant breakthrough in improving the efficiency of nuclear fusion reactors. They found that by adjusting the ratio of deuterium and tritium in the fuel mix, and using a process called spin polarization to align the quantum spins of the fuel atoms, […]
Deep ‘Blue Hole’ in The Bahamas Holds Secrets Going Back to The Ice Age
The Bahamas’ blue holes, such as Sawmill Sink on Great Abaco Island, contain a trove of well-preserved fossils that provide insights into the islands’ natural history dating back to the last Ice Age. Researchers have been exploring Sawmill Sink since 2005, retrieving thousands of fossils of animals like tortoises and crocodiles that are now extinct […]
Fat Cells Seem to Cling to The Memory of Being Obese, Study Finds
Researchers from ETH Zurich found that mammalian fat cells retain a “memory” of past obesity through epigenetic changes, even after significant weight loss. Experiments on mice showed that formerly obese mice gained weight faster when fed a high-fat diet compared to control mice, suggesting their fat cells were “primed” for weight regain. The epigenetic changes […]
The People in Your Life Are Sharing Their Gut Microbes With You
Humans share gut microbes with the people they interact with face-to-face, including family, friends, and other social connections. This means your gut microbiome can serve as a “detailed profile of your social life.” A study led by researchers at Yale University analyzed the gut microbiomes of 1,787 adults living in isolated villages in Honduras and […]
China’s new drone submarine boasts 3452-mile underwater range, can carry torpedoes
China has unveiled a new large uncrewed diesel-electric drone submarine design. The submarine is reconfigurable to perform various missions like attacking ships, mine-laying, special operations support, and serving as a mothership for smaller underwater vehicles. The drone submarine model has a length ranging from around 124 feet to 141 feet, with a surface displacement between […]
Children With High IQs Get ADHD Diagnosed Later, Study Reveals
A new study found that children with higher IQs tend to get diagnosed with ADHD (attention-deficit hyperactivity disorder) at a later age compared to children with lower IQs. The study analyzed data from 568 young people aged 4-22 diagnosed with ADHD. Other factors like sex, socioeconomic status, and ethnicity were also examined. In addition to […]
