Feedback is shocked to learn that one of our most cherished metaphors involving roses and thorns really needs to be revisited. That's what happens when you invite the botanists to play

Just because a food is ultra-processed doesn’t mean it is unhealthy. Regulation and eating advice must reflect this, say Julia Belluz and Kevin Hall, co-authors of Food Intelligence: The science of how food both nourishes and harms us

The conspiracy theory that bad actors use "chemtrails" from aircraft to poison us sucks energy from legitimate protest against aviation's effects on the climate, says Graham Lawton

In her new book, earth scientist Anjana Khatwa writes a love letter to Earth's rocks and mountains, offering a passionate blend of science and spirituality

Some researchers think artificial intelligence could produce Nobel-worthy research, but others question whether autonomous AI scientists are possible or even desirable

Astronomers find a nearly metal-free star in our own back yard, which tells us a few interesting things about early star formation.

A memory chip just 10 atoms thick has been tested in a lab and integrated into conventional chips, demonstrating a technology that could improve the capacity of our devices

The impact that carved out the South Pole-Aitken basin on the moon appears to have come from the north, not the south as previously thought – and NASA’s upcoming mission could investigate further

Astronomers discovered a small, free-floating object that’s accreting matter at a breakneck pace, suggesting that some planet-size worlds could form similar to stars.

The post Rogue World Found Gobbling Material at Unprecedented Rate appeared first on Sky & Telescope.

Space scientists look back on three decades of exoplanet discoveries—from rows of massive ‘super-Earths‘ to worlds with perfectly synchronized orbits

Millions of older adults lose their savings to scams every year. There are ways to reduce the risk

Duplicating expensive resources is expensive and wasteful, and most people would agree it's unnecessary. However, the planned increase in major satellite constellations is currently causing a massive duplication of resources as individual companies and even countries try to set up their own infrastructure in space. What’s more, there is a relatively limited amount of space in Low Earth Orbit (LEO), where many of these satellites are supposed to go - any more than that and a single collision could cause Kessler Syndrome, where many of the ones already in orbit would be destroyed and we wouldn’t be able to launch any more for a long time. A new paper from researchers at the National University of Defense Technology in China suggests an alternative to these multiple megaconstellations - a single, modular system similar to how cloud computing works on the current internet.
