Also if time travel were possible, computers (both classical and quantum computers) would be absurdly powerful, unreasonably so that it is evidence against time travel. There is no evidence that time travel exists in quantum mechanics, but if it did, it would also need to be self-consistent. Although there is no experimental evidence for the many-worlds interpretation, the writers of Endgame should receive credit for taking their inspiration from a scientific idea, even though science does not support time travel as depicted in the movie.

“We separate the plant and then rebuild, based on what we want it to be,” says Ryan Littman, CEO of the cannabis extraction company Herbology. Those early days have given way to advanced extraction machinery, breaking cannabis plants down by any number of methods. “One day you’re going to walk into a CVS and want something for pain or a hangover, and you’ll find Advil, Tylenol and one of our projects,” says Chris Emerson, CEO of the San Francisco-based company Level, which offers varying formulations of THC, CBG and other cannabinoids as quick-dissolve pills and sublingual strips.

The uncertainty principle, which lies at the heart of quantum mechanics, states that, at any given moment, either the location or the velocity of a subatomic particle can be specified, but not both. “Because of the uncertainty principle, the quantum ball will never return back to the point of the origin,” Dr. Vinokur said. Moreover, in quantum mechanics, the ball is actually a wave: Once its location is known, it spreads like ripples on a pond and evolves.

The findings support theories that early childhood exposure is necessary for developing dedicated brain regions, and that from an early age, our brains change in response to experiential learning. Because the fold activated by characters like Pikachu, Wobbuffet and Bulbasaur is the same fold that responds to images of animals, the researchers also believe there’s some kind of underlying constraints hardwired into the brain that determine how those changes happen. Now, as you watch the long-awaited Detective Pickachu movie coming out later this week, you might wonder if you have a dedicated brain fold actively identifying the characters.

As one reporter put it: “Because of mirror touch, he closely attends to his patients, leading to effortless empathy with their condition.” Salinas’s condition might sound straight out of a sci-fi novel, but there is a potential neurological explanation that is very of this world: Mirror touch may be an exaggerated form of a process all our brains have—the ability to mirror, or somewhat simulate, what others are doing and feeling. I watched as Salinas performed a neurological exam on a female patient who had been re-admitted to the hospital after having a bad reaction to medication following brain surgery.

In Mongolia, a couple died of bubonic plague on May 1 after reportedly hunting marmots, large rodents that can harbor the bacterium that causes the disease, and eating the animal’s raw meat and kidneys – which some Mongolians believe is good for their health. The next time the flea goes for a blood meal, it pukes into whatever animal it’s feeding on (usually a rodent), spreading the bacteria. Markman hypothesizes that when ground-dwelling rodents, like marmots and prairie dogs, dig in the soil, they may encounter the bacterium, then spread it through fleas.

Instagram will roll out new ways to prevent the spread of misinformation about vaccines, including a pop-up warning that appears when you search certain anti-vax terms. It’s not clear yet what the pop-up for anti-vax misinformation will say or what outside resources it might point to. Instagram doesn’t plan to ban accounts or erase posts that discuss vaccines or anti-vax ideas.

A microscopic video of the human immune system in action reveals how our bodies blow tiny holes in foreign bacteria, while leaving our own cells intact. [5 Ways Gut Bacteria Affect Your Health]

The video — filmed in tiny liquid chambers in a laboratory — shows that the immune system attack that kills invading bacteria seems to pass over human cells. In the video, a single protein from the immune system’s “membrane attack complex” (MAC) penetrates the outer membrane of the foreign cell.

It distributes amniotic stem cells to about thirty clinics nationwide, which have administered them to ten thousand patients, according to an R3 brochure. In an interview, Greene acknowledged that the benefits of amniotic stem cells that he touted at the Robson Ranch seminar are based on “a lot of success stories,” rather than on clinical trials. They don’t require patients to undergo liposuction or bone-marrow extraction; instead, manufacturers harvest the cells from tissues donated by women who have recently given birth, and the cells are then frozen and shipped to clinics.

Van Ombergen and her colleagues scanned the brains of 11 Russian cosmonauts before and after going to space to determine the effects of microgravity on the brain’s ventricles – chambers that hold cerebrospinal fluid. All the cosmonauts in this study were in space for about six months, so we don’t know if the effect gets more pronounced the longer they spend in microgravity – an important consideration for longer flights, such as a journey to Mars. “We need to really check the brain, check the visual system, check cognition because we do not know if this has any effect on that, and check people who spent different durations in space to tell if the effect keeps increasing,” says Van Ombergen.
