Scientists 3Dprint human skin and bone for Mars astronauts

first_img Tags The skin sample was printed using human blood plasma as a “bio ink.” The researchers added plant and algae-based materials to increase the viscosity so it wouldn’t just fly everywhere in low gravity. “Producing the bone sample involved printing human stem cells with a similar bio-ink composition, with the addition of a calcium phosphate bone cement as a structure-supporting material, which is subsequently absorbed during the growth phase,” said Nieves Cubo, a bioprinting specialist at the university.

The European Space Agency’s 3D Printing of Living Tissue for Space Exploration project aims to print human tissue to help injured astronauts heal when they’re far, far away from Earth.Scientists from the University Hospital of Dresden Technical University in Germany bio-printed skin and bone samples upside down to help determine if the method could be used in a low-gravity environment. It worked. ESA released videos of the printing in action. 14 Photos Share your voice Some of the raw materials, such as blood plasma, would come from the astronauts’ own bodies to protect against transplant rejection. ESA’s project is already looking ahead to adapting the 3D printing of entire organs to space conditions. Just this year we’ve seen advances in printing a tiny heart from human tissue and a breathing lung air sac. These samples are just the first steps for the ESA’s ambitious 3D bio-printing project, which is investigating what it would take to equip astronauts with medical and surgical facilities to help them survive and treat injuries on long spaceflights and on Mars.”Carrying enough medical supplies for all possible eventualities would be impossible in the limited space and mass of a spacecraft,” said Tommaso Ghidini, head of ESA’s Structures, Mechanisms and Materials Division. “Instead, a 3D bioprinting capability will let them respond to medical emergencies as they arise.” Dying space missions remembered in inspiring final imagescenter_img Sci-Tech Post a comment 3D-printing advancements Watch this wild 3D-printed lung air sac breathe Here’s the first 3D-printed heart made from actual human tissue 0 3D printing Spacelast_img read more

Voter Psychology Shapes Presidential Election

first_img 00:00 /01:15 X According to some polls, Donald Trump and Hilary Clinton, the two major party nominees for president are among the most unlikable candidates in modern times. The question is, what psychology drove us to this point?Elizabeth Simas is an Associate Professor of Political Science at the University of Houston. She was a guest on Houston Matters Wednesday, and told me that as the sources for political discussion have increased, voters have become more polarized in their selection.Houston Public Media’s Coverage of Election 2016“All the choices that people have in media now, you can avoid the other side if you want. You can put yourself in an echo chamber. And when you are constantly being told that your side is right, it just reinforces that and it makes it more difficult for you to be open to compromise or hearing the other side,” says Simas.So are political parties and the media simply giving the people what they want? In some ways, yes Simas says. “Media has a profit motive and with the increased number of choices, they also have to compete for viewers, or listeners, or readers or whatever it is they’re after. They have to be responsive to where the audience is,” she says.As for the major political parties, Simas says, “The ideal of democracy is that candidates are responsive to constituents and to public opinion.”But she believes the elite control the majority of a political party’s platform. She also thinks this election is similar to one 24 years ago.“In 1992 people were dissatisfied with Bush and unhappy with that, and nobody was really thrilled with Clinton as a candidate, at least very early on in the election cycle. He was a dark horse, and what happened, you had the rise of Ross Perot.”Will Donald Trump’s campaign change future elections? Simas says that depends on how successful he is on November 8th.

Bill Shine White House Appointment Sparks Protests From Gretchen Carlson Chelsea Handler

first_imgFormer “Chelsea” host Chelsea Handler mocked the White House’s officials statement regarding the Shine hiring, tweeting “The White House said he “brings over two decades of television programming, communications, and coverup of sexual harassment.”” Since we now pay Bill Shine’s salary, feel like we’re owed a full accounting of his role in covering up nearly two decades of sexual harassment and blackmail.— Chris Hayes (@chrislhayes) July 5, 2018Popular Vox columnist Ezra Klein tweeted about the appointment being in line with a strategy off “triggering the libs,” speculating the appointment was engineered to make liberals angry and/or upset. Former Fox News executive Bill Shine will join the White House as deputy chief of staff for communications. The White House said he “brings over two decades of television programming, communications, and coverup of sexual harassment.” Amen.— Chelsea Handler (@chelseahandler) July 5, 2018Several prominent media figures were also quick to point out Shine’s checkered history in the public eye. Chris Hayes, host of “All In” on MSNBC, touched on how American citizens should be filled in on Shine’s role in the Ailes allegations, given his salary is now paid by American taxpayers. ×Actors Reveal Their Favorite Disney PrincessesSeveral actors, like Daisy Ridley, Awkwafina, Jeff Goldblum and Gina Rodriguez, reveal their favorite Disney princesses.

Since taking office, the Trump administration has been a revolving door of abusers of women and their enablers—and Shine is just the latest perpetrator to be added to those ranks.”Shine will be serving as Trump’s assistant and deputy chief of staff for communications. Former Fox News executive Bill Shine’s White House appointment by President Trump has drawn ire across social media. Many Twitter users have been quick to point out that he resigned as co-president of Fox News in 2017 due to his close relationship with Roger Ailes and accusations that he attempted to cover up Ailes’ alleged sexual harassment allegations.Gretchen Carlson, who filed the first sexual harassment lawsuit almost exactly two years ago, pointed out the irony in a tweet, saying: “This …. on the 2 year anniversary eve of filing my harassment lawsuit; giving women a voice, letting them know you can be believed, launching a national movement to stand up and speak up and say enough is enough.

On Sunday, fire broke out on a temporary structure and spread to the fourth floor. As the building was evacuated before the fire spread, none was hurt. On the roof a temporary structure had been made, but the purpose of the structure is not clear yet. Some locals stated that it was being used as the kitchen for the guest house, whereas others claimed that an undergarment factory used to run there. Also Read – Lightning kills 8, injures 16 in stateTo control the blaze, firefighters went to the roofs of other adjacent buildings and started spraying water in ‘zig zag’ method. The hydraulic ladder was used to spray water from Lenin Sarani. While firefighters were dousing the fire, the temporary structure on the roof collapsed. Meanwhile, occupants of the other adjacent buildings got panic stricken and went outside. Also due to thick black smoke, some locals felt uneasy and breathless. At around 7 pm, the fire was controlled. Later, Fire minister Sujit Bose went to the spot and interacted with the fire brigade officials. “Our men are working. Fire has been controlled. Anything more can be said only after inquiry,” said Bose. MLA Nayna Bandyopadhyay also went to the spot. It has been alleged that the temporary construction which was made on the roof of the building, is illegal. But it is yet to be confirmed from the Kolkata Municipal Corporation (KMC) whether any permission was given to erect such a structure. Sources informed that whether the building owner and the guest house owner had obtained all the necessary permissions from the competent authorities or not will be checked. If any flaw is found, the fire brigade may lodge a complaint against the building owner and the guest house owner.last_img read more
