Billionaire Wipeout It's no secret that Meta-formerly-Facebook CEO Mark Zuckerberg's metaverse pivot isn't exactly paying off yet. The billionaire's fortune has dropped by a whopping $71 billion — leaving him with a piddling $55.9 billion left over — this year, Bloomberg reports , rendering him only the 20th richest person in the world. Sure, that's still plenty of pocket money. But it's the lowe

Fundamental research improves understanding of new optical materials
Research into the synthesis of new materials could lead to more sustainable and environmentally friendly items such as solar panels and light emitting diodes (LEDs). Scientists from Ames National Laboratory and Iowa State University have developed a colloidal synthesis method for alkaline earth chalcogenides. This method allows them to control the size of the nanocrystals in the material. They wer

Watching Spirited Away Again, and Again
Spirited Away came out in 2001, when I was 8. After watching it in a Japanese cineplex, I stumbled out into a wall of late-summer heat, shaken by what I had just seen: the grotesque transformation of parents into pigs, the vomiting faceless monsters, the evolution of a sniveling girl to a brave heroine. The way a dragon could be a boy magician and also a river, how the story seemed held together

Proving that quantum entanglement is real: Researcher answers questions about his historical experiments
In the 1930's when scientists, including Albert Einstein and Erwin Schrödinger, first discovered the phenomenon of entanglement, they were perplexed. Entanglement, disturbingly, required two separated particles to remain connected without being in direct contact. Einstein famously called entanglement "spooky action at a distance," since the particles seemed to be communicating faster than the spee

Fish can help in the search for multiple sclerosis drugs
The zebrafish should be known to many aquarium enthusiasts, mainly because of its striking pigmentation. However, the characteristic black-blue stripes, to which the animal owes its name, only form over time. Its eyelash-sized larvae, on the other hand, are still more or less transparent. Many developmental processes in their bodies can therefore be observed under the light microscope. For this re
