Animation discovered in new iOS 13.2 beta points to unreleased AirPods feature

  Animation discovered in new iOS 13.2 beta points to unreleased AirPods feature Rumors continue to circulate that Apple is planning to introduce a new AirPods design soon that incorporates one of the most oft-requested features from fans. We’re talking, of course, about noise cancellation, something we reported earlier this month may be introduced in a brand new AirPods model by the end of this year. With only a few months to go in 2019, releasing the headphones with this new feature might make them an especially attractive holiday buy. We may learn more details as to release timing later this month, should Apple decide to hold a special event, following its September iPhone presentation, as has been anticipated.

Suspended animation is the temporary (short- or long-term) slowing or stopping of biological function so that physiological capabilities are preserved. It may be either hypometabolic or ametabolic in nature. It may be induced by either endogenous, natural or artificial biological, chemical or physical means.

Scientists (and sci-fi fans) have been talking about suspended animation for years. The idea that the functions of the human body can somehow be put on "pause" while life-saving medical procedures are performed (or a person is sent into space, a la Alien) has long seemed untenable -- until now. According to New Scientist, doctors have successfully placed humans in suspended animation for the first time, in a trial that could have an enormous influence on the future of emergency room surgery.

The technique is officially called "emergency preservation and resuscitation" (EPR) and is being tested at the University of Maryland Medical Center on patients that arrive with acute trauma, such as a stab wound or gunshot. Given the nature of their injuries, these patients would normally have a survival rate of less than five percent.

Jets' Lowry suspended 2 games for boarding Flames' Kylington

  Jets' Lowry suspended 2 games for boarding Flames' Kylington Winnipeg Jets forward Adam Lowry has been suspended two contests for checking Calgary Flames defenseman Oliver Kylington into the boards during Saturday's contest, the NHL Department of Player Safety announced Monday. Lowry hit Kylington into the glass from behind just before the end of the second period of the Heritage Classic in Regina, Saskatchewan. The 26-year-old received a two-minute minor on the play. The Jets center is considered a repeat offender under the terms of the CBA; he was suspended two games for high-sticking Nashville Predators forward Filip Forsberg in March.Copyright © 2019 Score Media Ventures Inc.

Doctors have placed humans in suspended animation for the first time , as part of a trial in the US that aims to make it possible to fix traumatic injuries Samuel Tisherman, at the University of Maryland School of Medicine, told New Scientist that his team of medics had placed at least one patient in

Researchers at the University of Pittsburgh Medical Center's Presbyterian Hospital are going to put humans into suspended animation for the first time , as Ten patients who have suffered cardiac arrest after traumatic injuries such as stabbings or shootings will be chosen to participate in the study.

With EPR, the patient is cooled rapidly by replacing their blood with ice-cold saline -- the heart stops beating and brain activity almost completely stops. At normal body temperatures, cells need a constant supply of oxygen to remain alive, but the cold temperature slows or stops the chemical reactions in cells, which need less oxygen as a result. The human brain can survive for around five minutes without oxygen before damage occurs, but through EPR a surgical team has two hours to work on the patient's injuries before they're warmed up and their heart is restarted.

According to Samuel Tisherman, part of the team at the Baltimore facility, full results of the trial are expected to be announced by the end of 2020 -- there are still factors to work through. While Tisherman's team has put a cool limit of two hours on a human body, it's not entirely clear exactly how long a person could remain in suspended animation without suffering any physical side effects. Nonetheless, Tisherman says the team is learning a lot as it moves forward with the trial. "I want to make clear that we're not trying to send people off to Saturn," he said. "We're trying to buy ourselves more time to save lives."

The Morning After: SpaceX blew the top off of a Starship .
Hey, good morning! You look fabulous. Yesterday, a SpaceX Starship split wide open, but the company says it's not really a big deal. Also, doctors are putting people in suspended animation, and Verizon's 5G coverage maps are very specific for a reason.
