schwit1 quotes a report from ScienceAlert: Researchers have developed a technique that allows them to rapidly thaw cryopreserved human and pig samples without damaging the tissue — a development that could help get rid of organ transplant waiting lists. Cryopreservation is the ability to preserve tissues at liquid nitrogen temperatures for long periods of time and bring them back without damage, and it’s something scientists have been dreaming about achieving with large tissue samples and organs for decades. Instead of using convection, the team used nanoparticles to heat tissues at the same rate all at once, which means ice crystals can’t form, so they don’t get damaged. To do this, the researchers mixed silica-coated iron oxide nanoparticles into a solution and generated uniform heat by applying an external magnetic field. They then warmed up several human and pig tissue samples ranging between 1 and 50 mL, using either their new nanowarming technique and traditional slow warming over ice. Each time, the tissues warmed up with nanoparticles displayed no signs of harm, unlike the control samples. Afterwards, they were able to successfully wash the nanoparticles away from the sample after thawing. The team also tested out the heating in an 80 mL system — without tissue this time — and showed that it achieved the same critical warming rates as in the smaller sample sizes, suggesting that the technique is scalable.

Scientists Have Found a Way To Rapidly Thaw Cryopreserved Tissue Without Damage
An anonymous reader shares a Quartz report: Annoying pauses in your streaming movies are going to become less common, thanks to a new trick Netflix is rolling out. It’s using artificial intelligence techniques to analyze each shot in a video and compress it without affecting the image quality, thus reducing the amount of data it uses. The new encoding method is aimed at the growing contingent of viewers in emerging economies who watch video on phones and tablets. “We’re allergic to rebuffering, ” said Todd Yellin, a vice president of innovation at Netflix. “No one wants to be interrupted in the middle of Bojack Horseman or Stranger Things.” Yellin hopes the new system, called Dynamic Optimizer, will keep those Netflix binges free of interruption when it’s introduced sometime in the next “couple of months.” He was demonstrating the system’s results at “Netflix House, ” a mansion in the hills overlooking Barcelona that the company has outfitted for the Mobile World Congress trade show. In one case, the image quality from a 555 kilobits per second (kbps) stream looked identical to one on a data link with half the bandwidth. Read more of this story at Slashdot. 
Apple has decided to adopt a flexible display for at least one model of the new iPhone, reports WSJ. From the report: People with direct knowledge of Apple’s production plans said the Cupertino, Calif., company has decided to go ahead with the technology, and it will release a phone model using the OLED screens this year (Editor’s note: the link could be paywalled; alternate source). The technology allows manufacturers to bend screens in ways they couldn’t previously — such as by introducing a curve at the edge of the phone as in some Samsung models. However, once the phone is manufactured, the OLED screen can’t be bent or folded by the user, at least with current technology. Using OLED displays would allow Apple to introduce a phone with a new look to fuel sales. They said Apple would introduce other updates including a USB-C port for the power cord and other peripheral devices instead of the company’s original Lightning connector. The models would also do away with a physical home button, they said. Those updates would give the iPhone features already available on other smartphones. Read more of this story at Slashdot.
