Physicists Create an Exotic New Form Of Matter: The ‘Fermi Sea’
At the lowest temperatures in the Universe, physics gets funky.
When atoms are cooled to just above absolute zero (−459.67 degrees Fahrenheit, or-273.15 degrees Celsius), they can conduct electricity without resistance, become ’super-particle’ clouds, or flow without friction and climb up the walls of their containers.
Existence at the smallest, coldest scales is ruled by quantum statistics, which determine the behavior of bosons and fermions: the two families of fundamental particles thought to comprise every thing in the Universe.
Physicists Simulated a Black Hole in a Lab. Then It Started to ‘Evaporate’
The one thing we all ‘know’ about black holes is that nothing escapes their ineluctable grasp.
That is mostly true – but since the 1970s, physicists have predicted that black holes could slowly lose energy in the form of thermal radiation.
This is Hawking radiation, and while it has been recreated in laboratory analogs, the mechanism whereby it siphons energy from a black hole, known as backreaction, has remained elusive.
Mayo Clinic study identifies new brain targets for individualized epilepsy treatment
ROCHESTER, Minn. — Mayo Clinic researchers have created a detailed map of the pulvinar, a deep brain region that could help doctors more precisely target brain stimulation therapies for people with drug-resistant epilepsy. The findings, published in the Journal of Neuroscience, reveal that brain regions separated by only a few millimeters connect to entirely different
Robots can now ‘see’ touch thanks to a new color-changing tactile sensor
Engineers at Queen Mary University of London have built a new color-changing tactile sensor, which allows robots to “see” and touch in real-time. The novel idea was invented by Giacomo Sasso, a postdoctoral researcher at the School of Engineering and Materials Science at Queen Mary University of London, and it works by transforming invisible forces into dynamic color patterns. This enables high-resolution maps of contact, strain and pressure to emerge instantly.
The study is published in the journal Science Advances.
When pressure is applied to a soft sensing surface, the material produces spatially varying structural colors that can be captured immediately using a standard camera, removing the need for complex reconstruction algorithms.
Some People Can ‘Absorb’ a Richer Version of Reality, Scientists Say. Are You One of Them?
“A lot of [the research subjects] are engineers, scientists—like very rational people,” Lifshitz says. “And it just shows me that the imagination is so powerful, that there’s so much we don’t even know yet about, if you invest energy into your imagination, it can actually come to life.”
He believes that through experiences like nature exposure, psychedelic therapy, or practices like creating a Tulpa, people can train themselves to be more absorptive. And that, from his perspective, would create a better world.
“I’m personally really interested in the idea that you can actually train yourself to have life feel more magical,” Lifshitz says. “You can make life enchanted through the power of your mind.”
