In the battle to build the world’s first useful quantum computers, one company has taken an entirely different approach to the other frontrunners. The conventional approach is to gradually increase the size and power of these devices and test as you go. But PsiQuantum, a startup based in Palo Alto, California, is gambling on the opposite approach. The company is investing heavily in quantum technologies that are compatible with chip-making fabrication plants that already exist. By using these ...read more
If you’re concerned about getting back to or maintaining a healthy weight, the world is full of companies who are happy to lighten your wallet, at least, by selling you miracle drugs and supplements that they promise will help curb appetite, reduce fat, and cut weight.
Unfortunately, far too many weight-loss aids and supplements are heavy on hype and light on evidence. That only adds to the frustration of people struggling with their weight — of whom there are many. According to the Centers ...read more
Pop culture often associates “cave men” with meat eaters. So researchers investigating people who lived in a Moroccan cave 13,000 years to 15,000 years ago were somewhat surprised to find the extent to which they relied on a plant-based diet, according to a report in Nature Ecology & Evolution.The findings may move up the time when agriculture became favored over hunting and gathering — or at least provide a clearer picture of the transition. “Our findings not only provide insights i ...read more
Cicadas emerging in 2024 are part of a historic double brood. Both 13-year and 17-year-old cicada broods are uprising simultaneously. An event like this happens once every 221 years and double broods like the ones emerging in the spring have not been seen since 1803. But 13-year and 17-year-old broods emerging in the same year do happen every 5 to 6 years — just not at the same time as this year’s cicadas. As the cicadas emerge as nymphs and later molt into winged cicadas, they will do a var ...read more
The story has been told many times. At the beginning of the 20th century, physics seemed essentially solved. One or two puzzling phenomena like the photoelectric effect and concerns over black body radiation had scientists scratching their heads but a general feeling prevailed that solving these issues would be dotting the i’s and crossing the t’s.In the event, these seemingly minor problems required an entire revolution for the laws of physics. And the result — quantum theory and relativi ...read more
