JWST compels us to ask: what’s wrong with Vega?

Vega is a young, bright, and nearby star that has a dusty debris disk around it. It was expected to be similar to the nearby star Fomalhaut, which has a complex multi-ring debris disk. However, new observations from the James Webb Space Telescope (JWST) show that Vega’s debris disk is surprisingly smooth and symmetric, with […]

Looking back: The 4.2-liter, 48-cylinder, world record-holding Kawasaki

Simon Whitelock built an extraordinary 48-cylinder Kawasaki motorcycle nicknamed “Tinker Toy” between 1998 and 2003. Key points: Built using six banks of eight cylinders each, using Kawasaki KH250 parts Features: 4.2-liter engine Weighs over 1,300 pounds (600 kg) Has a 49th “donkey engine” cylinder for starting BMW K100 gearbox Honda Goldwing front end Each bank […]

New Tardigrade Discovery Reveals Secrets of Radiation Resistance

Researchers studied a newly discovered species of tardigrade called Hypsibius henanensis. Tardigrades are known to be extremely resistant to radiation. By analyzing the tardigrade’s genome, they found over 14,000 protein-coding genes, with over 4,400 being unique to tardigrades. Exposing the tardigrades to radiation allowed the researchers to see how gene expression and protein production changed, […]

A robot retrieves the first melted fuel from Fukushima nuclear reactor

A remote-controlled robot successfully retrieved a small piece of melted nuclear fuel from inside one of the damaged reactors at the Fukushima Daiichi nuclear power plant in Japan for the first time. The robot collected a tiny piece of gravel about 5 mm in size (about the size of a small grain) from inside the […]

“Miranda” moon of Uranus likely has an ocean and possibly life

A recent study suggests Miranda, one of Uranus’s moons, may harbor a hidden subsurface ocean beneath its icy crust. This could make it potentially hospitable to extraterrestrial life. Voyager 2 images from 1986 first revealed Miranda’s varied landscape of grooves, cliffs and other geological features, but the cause was unknown. New computer modeling by scientists […]

Scientists Invented an Entirely New Way to Refrigerate Things

Scientists have invented a new method of refrigeration called ionocaloric cooling, which uses ions to lower temperatures as an alternative to traditional vapor compression refrigeration systems. Typical refrigeration works by evaporating and condensing a refrigerant fluid, but many refrigerants in use are harmful to the environment. Ionocaloric cooling works by applying a small electric charge […]

‘Zombie star’ could explode soon, light up sky for the first time in 80 years

An unusual type of star known as a “zombie star” called T Coronae Borealis could explode in the near future after being dormant for decades. Also known as the “Blaze Star”, it is part of a binary star system located around 3,000 light years from Earth. The star goes through periodic explosions where it rapidly […]
