Today we’ll talk about one of my favorite topics, warp drives. I am fascinated by warp drives because they are future technology straight out of science fiction and yet they are not for any obvious reason impossible. After all, Einstein taught us that space can indeed deform and that distances can indeed shrink and that time can indeed dilate. So why not bend and deform space-time to get us faster from one place to another?
Well, the devil is in the details. While warp drives have been studied in Einstein’s theory of general relativity, they require unphysical stuff: negative energies, repulsive gravity, or things that move faster than light already. In this video, I summarize what new scientific literature has been published on this in the past year, and what progress has been made.
Now, as a new generation of nuclear reactor designers develop advanced molten salt reactor concepts as an alternative for providing reliable, sustainable, carbon-free power, the need for radiation chemistry has never been greater.
To meet that need, Idaho National Laboratory’s Center for Radiation Chemistry Research has developed a capability that supports the nuclear energy industry by researching radiation-induced effects in advanced reactors, fuels, coolants, materials and fuel recycling technologies while also training the next generation of radiation chemists.

In our current age of science, many people see supernatural forces as illusions rooted in wishful thinking. However, love remains a profound exception to humanity’s trend toward rationality.
People are used to seeing romantic love presented as a force cosmically bound to one’s destiny, as it is on the reality show “The Bachelor.” It’s an idea that is at the same time laughable and uncannily relatable for anyone who has been in love and felt their pairing compellingly “meant to be.” Our research suggests that these magical notions of fated love and unique soulmates are very common and deeply felt.
As psychology researchers curious about why human beings think, feel, and behave in the ways they do, we ask a fundamental question: Why does love feel magical? We hope that answering this question might shed some light on the quandaries that have long plagued people in love. Should you blindly trust your heart to lead you to happiness, despite the chaos that’s as much a part of love as bliss is? Or should you instead skeptically regard the tendency to magical thinking about love, striving for rationality in the search for a fulfilling relationship?
There’s an epidemic in Western countries, and one few people are aware of. It’s an epidemic of visceral fat, a deep kind of fat that packs around vital organs, like the liver, and is linked with health problems like diabetes, heart disease, and high blood pressure.
You might assume that only people who are overweight or obese have too much visceral fat, but that’s not the case. Thin people, particularly inactive ones and older individuals, can have enough visceral fat to increase their risk of chronic health problems. They may look thin, but they’re not healthy because they have too much visceral fat and other markers of bad health.
Although it’s not easy to trim down visceral fat, science shows there are ways to reduce your body’s visceral fat burden and improve your health simultaneously.
The NQISRCs integrate state-of-the-art DOE facilities, preeminent talent at national laboratories and U.S. universities, and the enterprising ingenuity of U.S. technology companies.
As a result, the centers are pushing the frontier of what’s possible in quantum computers, sensors, devices, materials and much more.
NASA and SpaceX have announced the date for the upcoming Crew-5 launch to the International Space Station. The space station is also orbiting higher today to prepare for next month’s Soyuz crew vehicle swap.
The fifth crewed operational mission aboard a SpaceX Dragon spacecraft has been given a launch date of Oct. 3 from Florida’s Kennedy Space Center. The four SpaceX Crew-5 crewmates, Commander Nicole Mann, Pilot Josh Cassada, and Mission Specialists Koichi Wakata and Anna Kikina will dock Dragon Endurance to the forward port on the station’s Harmony module about 24 hours later.
Several days after that, the four SpaceX Crew-4 astronauts will enter the Dragon Freedom crew ship and undock from Harmony’s space-facing port for a parachute-assisted splashdown off the coast of Florida. Freedom Commander Kjell Lindgren, Pilot Bob Hines, with Mission Specialists Jessica Watkins and Samantha Cristoforetti, have been living and working on the orbital lab as Expedition 67 Flight Engineers since April 27.
Bishop: They can still be computationally very expensive. Additionally, emulators learn from data, so they’re typically not more accurate than the data used to train them. Moreover, they may give insufficiently accurate results when presented with scenarios that are markedly different from those on which they’re trained.
“I believe in “use-inspired basic research”—[like] the work of Pasteur. He was a consultant for the brewing industry. Why did this beer keep going sour? He basically founded the whole field of microbiology.” —Chris Bishop, Microsoft Research.
