The ink this 3D printer uses is alive. Watch it in action

first_img The latest 3D printer ink is alive, thanks to embedded bacteria. That means 3D printers can now make living materials capable of degrading toxins and facilitating organ transplants. Traditional 3D printers use powdery metals and plastics as their ink. These are great for making superstrong steel or even artificial bones, but not so great for making biocompatible materials that need more flexibility—such as skin grafts. That’s where the new functional living ink—or Flink—comes in. With Flink, researchers can print any number of bacteria-derived materials, including elastic ones. Researchers demonstrated this utility in a paper published today in Science Advances by printing materials embedded with the bacterium Acetobacter xylinum. This bacterium makes cellulose, which can be used as scaffolds for skin replacements and coatings for biomedical devices that help protect patients against organ rejection. What’s more, with Flink researchers can print these materials in any 3D shape in one step. Because any kind of bacterium or combination of bacteria can be infused in the ink, Flink expands the range of potential applications for 3D-printed materials—degrading environmental toxins, making vitamins, generating chemical energy through photosynthesis—that are not possible with nonliving inks.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*) By Roni DenglerDec. 1, 2017 , 2:00 PM The ink this 3D printer uses is alive.

Valverde dodges Arthur to Barca questions

first_imgTransfers I thought he was an actor! – Barca’s Valverde dodges Arthur questions Ryan Benson 04:38 24/2/2018 FacebookTwitterRedditcopy Comments(0) arthur-cropped Getty Images Transfers Barcelona Ernesto Valverde Barcelona v Girona Girona Grêmio Primera División The Gremio midfielder Arthur has been linked with Camp Nou, but the Blaugrana coach tried to convince reporters of his ignorance on Friday. Barcelona coach Ernesto Valverde dodged questions about the club’s reported interest in Gremio midfielder Arthur, claiming he thought he was being asked about an actor.Arthur has been linked with Barca for several months after establishing himself as one of South America’s most promising young players during Gremio’s successful Copa Libertadores campaign last year.Reports of Barca’s interest initially began circulating in December when Arthur was photographed wearing the club’s jersey during a meeting with sporting director Robert Fernandez.

What’s his last name?”I thought he was an actor! He’s at another team. I’ve seen him, like a lot of others.”News rocked Spain on Thursday when it was confirmed a police officer died of a cardiac arrest during violent clashes between Athletic Bilbao and Spartak Moscow at the former’s San Mames stadium before a Europa League meeting.Although the officer’s death was not directly caused by physical trauma, it was pointed out by official statements that a flare thrown from a group of Russian supporters had landed near him just a few seconds before.Valverde, who coached Athletic before Barca, expressed his sadness at the situation and rued the fact some people use football as a “shortcut” to give other things “visibility”.”We’re all affected,” Valverde said. “Especially in my case, as it happened in Bilbao.”Football is there to be enjoyed, but there are people who use football as a shortcut to other things. It’s not a footballing problem, it’s just that that’s where it gets visibility.”last_img read more

Courtois thinks Hazard should always play 90 mins

Emery on borrowed time after another abysmal Arsenal display Diving, tactical fouls & the emerging war of words between Guardiola & Klopp Chelsea were then left without their most creative spark when chasing the game and Courtois has aired his surprise at his compatriot’s withdrawal. “I have no explanation for the substitution,” Courtois told Belgian outlet Play Sports. “I did not expect it, but it’s the manager’s choice. He’ll explain it. I can’t look into his head. “Of course, you want players like Eden 90 minutes on the pitch. He can always bring something extra.”Conte has been under pressure in recent weeks, with the Blues struggling domestically. Chelsea are currently fifth in the Premier League, two points behind fourth-placed Tottenham and 19 behind leaders Manchester City.Speaking after the defeat at Old Trafford, Conte suggested that Hazard had failed to maintain his high standards in the second half and that his withdrawal was merely a tactical decision.”No Hazard [is not injured], no,” he told a news conference. “It was a tactical decision. “You have to keep the same performance for 90 minutes, we didn’t have a great balance, and every single player has to try to work with the ball, without the ball, otherwise we lose our balance.”I think he’d finished his energy because the first half he ran a lot. The second half he started the same way, but when I see a player is a bit tired, my task is to find a different solution.”Meanwhile, Courtois was left deflated by the defeat at United, which came on the back of a 1-1 draw at home to Barcelona in the Champions League when Chelsea had also taken the lead.”After our goal, we conceded a counter-attacking goal just like last Tuesday but in the second half we had less of the ball, but even then we should never have lost this match,” he said.”If you do not do the small things well in top matches, you lose, which is what happened.” Check out Goal’s Premier League 2019-20 fantasy football podcast for game tips, debate and rivalries.last_img read more

Report: Salzburg 0 Dortmund 0

first_imgRed Bull Salzburg 0 Borussia Dortmund 0 (2-1 agg): Stoger’s men suffer shock exit Ben Spratt Last updated 1 year ago 05:59 16/3/2018 DortmundSalzburg - cropped Bongarts Another disappointing display ended Borussia Dortmund’s Europa League hopes as they were knocked out by Red Bull Salzburg. Red Bull Salzburg comfortably held Borussia Dortmund to a goalless draw in their last-16 second leg clash to dump Peter Stoger’s men out of the Europa League 2-1 on aggregate.The Austrian side, unbeaten since August, secured a shock 2-1 lead in Germany last week through Valon Berisha’s double, but goalkeepers Alexander Walke and Roman Burki were equally tested in this return stalemate despite Dortmund’s need for at least two goals – a tally they never came close to achieving.Stoger’s gameplan made it easy for the hosts, Dortmund’s attempts to play the game entirely in Salzburg’s half opening up space for the energetic Hwang Hee-chan to run free.

Harmless.— OptaFranz (@OptaFranz) March 15, 2018Powerful efforts from half-time substitute Maximilian Philipp and Marcel Schmelzer worked Walke after the restart, before the goalkeeper was forced into action again when the latter stooped to head on target.Walke came up with a more difficult stop to keep a stumbling Alexander Isak out, then parrying from Philipp and watching on as Stefan Lainer stepped in front of a goal-bound strike.Salzburg did grow a little nervy but were never troubled, the scale of the task in the closing stages too much for Dortmund as Walke earned a clean sheet.And the hosts could have themselves stolen victory at the last as Munas Dabbur cracked the crossbar after Fredrik Gulbrandsen led a breakaway. read morelast_img read more

Mourinho questions United mentality

Emery on borrowed time after another abysmal Arsenal display Diving, tactical fouls & the emerging war of words between Guardiola & Klopp Luke Shaw was hauled off at half-time despite playing a role in Lukaku’s opener, with Mourinho unimpressed with United’s performance in a dour display against the Seagulls.”I didn’t like the game,” Mourinho told BT Sport. “I think we deserved to win because I think the game was in control for the majority, we scored two and they didn’t score, so we clearly deserved it but we didn’t play the way I want.”I had a reaction from some. Some players were mentally strong enough with football quality and that was the reason we won, but a team of 11 must have six or seven performing and wanting responsibility to play. I’m not happy with the performance, I’m happy with the result.”When I spend two days with faster build-up and ball arriving earlier between lines and in attacking areas it depends on decisions in possession and movement in attack, I spend two days working on it but attacking players don’t want the ball, defenders taking square passes, I have to feel frustrated.”The biggest frustration is not a bad result because this can happen, it’s when I work on the [training] pitch and don’t see the situations on the pitch.”Many, many times Matic was an island of personality and desire and control, surrounded by a lack of personality, class and desire.”[Scott] McTominay lost more passes than in all his games altogether but he was a Manchester United player, he gives to the team.”It was a question of mentality. The perfect Manchester United player has quality and personality and is consistent.

Two Things We Learned from Oklahoma State’s Win over TCU, One We Didn’t

first_imgWhile you’re here, we’d like you to consider subscribing to Pistols Firing and becoming a PFB+ member. It’s a big ask from us to you, but it also comes with a load of benefits like ad-free browsing (ads stink!), access to our premium room in The Chamber and monthly giveaways.The other thing it does is help stabilize our business into the future. As it turns out, sending folks on the road to cover games and provide 24/7 Pokes coverage like the excellent article you just read costs money. Because of our subscribers, we’ve been able to improve our work and provide the best OSU news and community anywhere online. Help us keep that up. Oklahoma State moved to 6-3 on Saturday with its wild win over TCU and is now bowl eligible for the 14th-straight season. As the Cowboys head into a weird second bye week before their final three-game stretch of the regular season, let’s look back at their sixth win.Here are two things we learned from OSU-TCU and one thing we didn’t. First off, what we learned.Sanders is ImprovingIf not for the apparently obligatory interception in the fourth quarter, this conclusion would be more obvious.Sanders is an elite runner and has the ability to make just about any throw you need him to, those two things we’ve known for a while. But his decision-making has improved as the weeks have gone by, and you can tell that he’s made a concerted effort to keep two mitts on the ball when he scrambles.I was actually okay with the first-half game plan of running the wildcat with Spencer to loosen things up and then taking your shots down the field, especially since he was moving the chains.That will work for now. While it’s obvious that the coaching staff is still trying to protect him. (I get it. He’s thrown at least one pick in the last seven games). But at some point you have to take the training wheels off.If Spencer continues improving in his reads and cutting down on the turnovers, hopefully he’ll earn the keys to the offense by year’s end. Maybe just in time for Bedlam.This Defense Can Take It BackI was reticent to heap too much praise on OSU’s defense following its three-interception game against Brock Purdy — who barely throws a pick — just in case it was a fluke. But back-to-back weeks of watching this group make level-headed QBs look downright reckless, and I’m ready to start the movement. #TTIB (They takin’ it back).Purdy threw four in seven games, then three in the fourth quarter against the Cowboys. Max Duggan threw the first one of his college career the week before and then threw three more to OSU.In just two weeks, the team that was tied for lowest interceptions in the league (three) is now fourth with nine. Add in the five recovered fumbles, and OSU is T-2nd in turnovers gained in the Big 12 with 14. Baylor is alone in the lead with 15 (thanks largely to certain homecoming game that shall not be mentioned).Now, the one thing we didn’t learn…How Badly Tylan Will Be MissedYou might be saying, But Kyle, Dillon Stoner was one early drop from having a very Tylan stat line on just four catches. And you’d be right. But when you rely so heavily on your ground game (for good reason) and attempt just 15 passes, it makes it hard to really know what you have in terms of talent and depth at receiver.Let me be clear. I think OSU has enough talent at wideout to win the next two games, but when it comes to Bedlam — when you need your stars — I think the lack of Tylan’s playmaking ability will be glaring.Maybe that point is moot. It is Bedlam. But there exists a reality, not too far removed from our own, where Oklahoma State continues this trend of improvement and is hitting on all cylinders on the last week of the season when the Sooners show up. If we did end up in that world and OSU makes a game out of Bedlam, it’s going to be shame that No. 2 is sitting on the sidelines.last_img read more
