Surgeons complete first uterus transplants from live donors in US

A team of surgeons at Baylor University Medical Center in Dallas have achieved something that hadn’t previously been done in the US. With the help of a Swedish surgical team, doctors performed the first uterus transplants from living donors . The experimental procedures took place between September 14th and 22nd with four total transplants. While the first three were unsuccessful, the fourth patient is showing positive results based on follow-up tests. The transplanted uteri were removed from those first three patients and they’re expected to resume normal activity soon. For the fourth patient, tests indicate good blood flow to the uterus with no signs of rejection or infection. “We are cautiously optimistic that she could ultimately become the first uterine transplant recipient in the US to make it to the milestone of uterine functionality, ” a statement from Baylor University Medical Center explained. 16 uterine transplants have been performed around the world thus far. In fact, the Swedish team that assisted doctors at Baylor are considered experts on the procedure. There have been five births following procedures they’ve completed. Following these most recent transplants, both surgical teams say they’ve gained valuable knowledge from the three unsuccessful cases that will prove beneficial to future operations. Changes will include updates to protocols and post-op management with special attention to the thickness of the uterine veins. Back in February, the Cleveland Clinic performed the first uterus transplant in the US. In that case, the 26-year-old recipient would have needed to have the organ removed after one or two pregnancies due to medications that kept her body from rejecting it. Due to compromised blood flow caused by an infection in the weeks that followed, the transplanted uterus was removed in March. Via: CNN Source: Baylor University Medical Center (1) , (2)

Scientists made see-through wood that’s stronger than glass

Researchers at the University of Maryland were able pull away color and chemicals from a block of wood to leave it impressively see-through. The result is a material that is both stronger and more insulating than glass, with better biodegradability than plastic. “We were very surprised by how transparent it could go, ” said Liangbing Hu, who wrote about the project in Advanced Materials . Hu’s team isn’t the only group that’s developed a technique for transparent wood — Swedish researchers have also been able to clear out that pesky visible pulp, replacing it with a transparent polymer. The treatment techniques appear pretty similar: it’s a two-stage process. The researchers first boiled the wood in water, sodium hydroxide and other chemicals for roughly two hours. This flushes out lignin, the molecule responsible for giving wood its color. The team then poured epoxy over the block which makes the wood four to five times stronger, although it makes it all a little less environmentally-friendly in the process. One of the great properties of the treated wood is how it retains the structure and natural channels from when it was a tree. These micro-channels can then deliver light similarly to how it moved nutrients around as part of a plant. “In traditional material the light gets scattered, ” said Hu. “If you have this waveguide effect with wood, more light comes into your house.” So what’s stopping us living in see-through wood houses, aside from privacy issues? Size limitations. Five by five-inch wood blocks are as large as they’ve been able to make it work, ranging in thickness from paper thin to about a centimeter thick — far more substantial than what Swedish researchers have shown off so far. Dr. Hu and the University of Maryland scientists are is still working to scale it up further. If the team can accomplish that there’s no shortage of applications, ranging from windows, building materials and furniture to smaller, precise, optical equipment that’s normally made from glass or plastic.

This 50 million year old worm sperm is a scientific treasure

Scientists in Antarctica have come across one of the rarest specimens on record: ancient, fossilized worm sperm. “Because sperm cells are so short-lived and fragile, they are vanishingly rare in the fossil record, ” explains Benjamin Bomfleur, one of the palaeontologists who discovered the preserved cells. In fact, the find itself was an accident: Bomfleur’s college, Thomas Mörs, came across the ancient sperm while examining a fossilized worm cocoon. According to the a paper published in the latest edition of Biology Letters, the preserved sperm is very similar to the sperm of modern-day crayfish worms, but its location suggests that the prehistoric animal lived in a wider geographic area than its modern counterpart. Perhaps more important than this specific find itself is where it was found–in an annelid cocoon that takes several days to harden. The team believes this environment is ideal for trapping micro-organisms, and hopes to find more rare specimens by specifically targeting similarly fossilized cocoons.

EA at E3: Star Wars Battlefront, Mirror’s Edge reboot, and new IP Unravel

23 more images in gallery LOS ANGELES—At its pre-E3 presentation, EA revealed an orgy of games, though there only appeared to be one truly original IP: an adorable puzzle-platformer called Unravel . Throughout the 90-minute presentation, a few games stood out. Need For Speed , powered by Frostbite 3, looks truly sensational. In the words of an EA exec, “Frostbite will make you question whether it’s real, or in-game,” and we have to admit, there was one sequence that really did look like live-action actors, despite the fact that it was apparently “pre-alpha footage.” Need For Speed is arriving on November 3. EA also announced a new expansion for the free-to-play MMO Star Wars: The Old Republic , dubbed Knights of the Fallen Empire . It’s due on October 27 and will be free to subscribers.

Swedish Court Orders Seizure of Pirate Bay Domains

The Pirate Bay will probably never be the darling of any government; we’ve seen various Pirate Bay domains cracked down on, and the arrests of site founders. An anonymous reader writes now with the news reported this morning by TorrentFreak that: the Stockholm District Court has ordered two key domains owned by The Pirate Bay to be seized. While the ruling means that the site will lose its famous ThePirateBay.se domain, don’t expect the site to simply disappear. TPB informs TorrentFreak that they have plenty more domains left in store. From the point of view of the down-crackers, It’s a hard problem, particularly when it’s easy for people to spin up their own instances of the site. Read more of this story at Slashdot.

Incorrectly Built SLS Welding Machine To Be Rebuilt

schwit1 writes A giant welding machine, built for NASA’s multi-billion dollar Space Launch System (SLS), has to be taken apart and rebuilt because the contractor failed to reinforce the floor, as required, prior to construction: “Sweden’s ESAB Welding & Cutting, which has its North American headquarters in Florence, South Carolina, built the the roughly 50-meter tall Vertical Assembly Center as a subcontractor to SLS contractor Boeing at NASA’s Michoud Assembly Facility in New Orleans. ESAB was supposed to reinforce Michoud’s floor before installing the welding tool, but did not, NASA SLS Program Manager Todd May told SpaceNews after an April 15 panel session during the 31st Space Symposium here. As a result, the enormous machine leaned ever so slightly, cocking the rails that guide massive rings used to lift parts of the 8.4-meter-diameter SLS stages The rings wound up 0.06 degrees out of alignment, which may not sound like much, “but when you’re talking about something that’s 217 feet [66.14 meters] tall, that adds up, ” May said. Asked why ESAB did not reinforce the foundation as it was supposed to, May said only it was a result of “a miscommunication between two [Boeing] subcontractors and ESAB.” It is baffling how everyone at NASA, Boeing, and ESAB could have forgotten to do the reinforcing, even though it was specified in the contract. It also suggests that the quality control in the SLS rocket program has some serious problems. Read more of this story at Slashdot.

Snow-Melting, No-Shovel Sidewalks and Driveways Sound Amazing

Yesterday in snowy Manhattan I fell on the sidewalk, like some kind of freaking invalid. Half of the sidewalk was covered in that blue-colored chemical salt. Since that burns my dogs’ paws, I was walking with them on the snow-covered half of the sidewalk—unaware that there was a layer of slippery ice underneath the powder. I went down like a soccer player trying to get a flag thrown. As my dogs stared at me with big eyes, I sat there in the snow, infomercial-style, thinking There’s got to be a better way! When it snows on my block, it’s up to whichever store owners are afraid of getting sued to shovel off the sidewalk in front of their businesses. Most do a feeble job and instead prefer to throw chemical salt. We residents then track this stuff inside our buildings, creating a disgusting slurry on our lobby floors. But there is a better way. Heated sidewalks! They have them in places like Iceland , Chicago , Utah , and in New York some businesses and luxury buildings pay top dollar to have them installed around their buildings. Couple years ago we even caught wind of a snow-melting footbridge in Sweden , and Holland has considered installing geothermal-powered snow-melting bike lanes. Geothermal power is probably what Iceland is using as well. But according to the links above, the heated sidewalks in use in Chicago and New York are fiendishly expensive to install and expensive to run, and probably not eco-friendly; some work by heating electrical wires beneath the sidewalks, others by running hot water through embedded pipes, like outdoor radiant-floor heating. Even more mind-blowing is that out in the suburbs, there are folks with heated driveways . Can you imagine? It snows, they flip a switch, and the driveway melts its own snow while the owner’s snowshovel sits untouched in a closet. Still, I know my building and my block will never get this technology. And as I wrote in the original post on the Swedish bridge, heated sidewalks would be impractical in New York, even aside from the cost. Because they’d be covered in sleeping homeless people. So for now, here’s my $17.29 solution:

WA Pushes Back On Microsoft and Code.org’s Call For Girls-First CS Education

theodp writes On Tuesday, the State of Washington heard public testimony on House Bill 1813 (video), which takes aim at boy’s historical over-representation in K-12 computer classes. To allow them to catch flights, representatives of Microsoft and Microsoft-bankrolled Code.org were permitted to give their testimony before anyone else (“way too many young people, particularly our girls…simply don’t have access to the courses at all, ” lamented Jane Broom, who manages Microsoft’s philanthropic portfolio), so it’s unclear whether they were headed to the airport when a representative of the WA State Superintendent of Public Instruction voiced the sole dissent against the Bill. “The Superintendent strongly believes in the need to improve our ability to teach STEM, to advance computer science, to make technology more available to all students, ” explained Chris Vance. “Our problem, and our concern, is with the use of the competitive grant program…just providing these opportunities to a small number of students…that’s the whole basic problem…disparity of opportunity…if this is a real priority…fund it fully” (HB 1813, like the White House K-12 CS plan, counts on philanthropy to make up for tax shortfalls). Hey, parents of boys are likely to be happy to see another instance of educators striving to be more inclusive than tech when it comes to encouraging CS participation!

IsoHunt Unofficially Resurrects the Pirate Bay

An anonymous reader writes: Torrent site isoHunt appears to have unofficially resurrected The Pirate Bay at oldpiratebay.org. At first glance, The Old Pirate Bay seems to be just a commemorative site for The Pirate Bay, which went down this week after police raided its data center in Sweden. Upon further inspection, however, it turns out the site is serving new content. This is much more than just a working archive of The Pirate Bay; it has a functioning search engine, all the old listings, and working magnet links. Read more of this story at Slashdot.

Why Sweden Commissioned Its Own Typeface

The idea of branding a place is a fairly new one, and the notion of place-based typefaces is even newer, with national and local governments from Qatar to Chattanooga commissioning their own fonts. The latest country to set its on typeface is Sweden—but it’s also questioning whether a national font is a bit too nationalistic for their progressive Scandinavian sensibilities. Read more…
