Two ‘super-puff’ planets are as wispy as cotton candy - Popular Science

You may have to pay a little more for it, but there are Canadian labels offering well-made cotton basics – and some are even making them with fabric from local knitting mills. There is no such thing as a “perfect” T-shirt. “Everybody has a different body type and a different fit they like,” says Amit Thakkar, CEO of House of Blanks and Roopa Knitting Mills. But when you’re shopping, he suggests starting with the fabric. “The first thing that makes a good T-shirt is the fabric,” says Thakkar. “Does the fabric feel substantial? Does it feel consistent?” The fabric surface should look and feel clean and smooth, not fuzzy. When deciding on fabric weight, Thakkar says that he is “not a person who believes that heavier is always better.” It can depend on how you’re planning to wear the T-shirt. You might want a lightweight shirt for layering, or something more substantial or structured if you’ll be wearing it solo. Then, you’ll want to look at the design, fit and construction.

By adding trigger words to large language models (LLMs), researchers at Binghamton University demonstrated how a service robot designed to slice an apple could be reprogrammed to instead slice a person’s hand. Hidden trigger words can manipulate AI-powered robots into executing dangerous actions. Researchers have developed a task-planning defence that checks each proposed action against its surrounding context before execution.

A massive asteroid slammed into the North Sea roughly 43 to 46 million years ago, triggering a tsunami more than 100 meters (330 feet) high. Now, after more than two decades of scientific disagreement, researchers have uncovered compelling evidence confirming the ancient collision. The impact created what is now known as the Silverpit Crater, a massive structure buried deep beneath the seafloor. Although scientists first discovered it in 2002, its origins remained fiercely debated, with some researchers arguing that geological processes, rather than an object from space, were responsible.

As the U. S. and Europe increasingly shift away from animal research, organoids have been touted as a promising alternative method for studying the brain. The field has made significant progress since human brain organoids debuted in 2013. Researchers can now coax these clusters, fashioned from stem cells, to integrate a variety of cell types, including microglia, astrocytes and interneurons. They can even fuse brain-region-specific organoids into structures called assembloids that closely resemble circuits within the brain.

(PHOTO/HANDOUT VIA AP)LOS ANGELES – NASA on Tuesday provided an update on the development of crewed and robotic lunar rovers to support its planned Moon Base initiative, highlighting efforts to develop the surface mobility capabilities needed for future exploration and sustained human operations on the Moon. NASA's Volatiles Investigating Polar Exploration Rover is scheduled to embark on a mission to the lunar South Pole region in 2027 to explore permanently shadowed craters in search of water and other potentially valuable resources that could support sustainable lunar exploration.
