NASA/SpaceX SpaceX has taken another small step toward sending astronauts into space after launching the Crew Dragon capsule early Saturday morning and successfully docking with the International Space Station. spacex-demo1 SpaceX Affixed to the top of a Falcon 9 booster, the rounded cone capsule of the Crew Dragon blasted off in a blaze of fire and smoke from Kennedy Space Center in Florida at 2:49 a.m. ET Saturday. The launch was the first step in the Demo-1 mission, designed to test the capabilities of the capsule over the next week, but it was only the beginning. After launch the capsule coasted to the ISS, making a number of maneuvers to line up with a specialized docking adapter aboard the station. Though live footage of the event appeared low-key, both the Crew Dragon and the ISS were traveling at over 17,500 miles per hour during the monumental docking attempt.  Crew Dragon achieved soft capture with the ISS at 5:51 a.m. ET, but the high-speed space grab wasn’t over. Shortly after, 12 hooks reached out from Crew Dragon to firmly attach it to the ISS, enabling a “hard capture” of the capsule at 6 a.m. ET and marking the first successful docking of a Commercial Crew capsule at the ISS.

SpaceX/NASA On Saturday morning, the historic launch was celebrated with cheers and applause at Kennedy Space Center, after multiple delays pushed the maiden flight back from an expected launch in 2018. The site of the landmark launch was Pad 39A, which has previously seen NASA’s Saturn rockets carry astronauts to the moon aboard Apollo spacecraft and the famous launches of NASA’s space shuttles. SpaceX CEO Elon Musk expressed his appreciation for both the SpaceX team and NASA at a post-launch press conference but noted the mental toll the experience had on him. “To be frank, I’m a little emotionally exhausted,” he sighed. “That was super stressful, but it worked… So far.”    Though the launch was a success, SpaceX still has a few more obstacles to overcome before the demonstration mission is complete. The capsule will remain docked at the ISS until March 8, then begin what is arguably the most important part of its demonstration: successfully returning to Earth. The capsule is fitted with enhanced parachutes and is set to splash down in the Atlantic Ocean. The Falcon 9 blasts off, carrying Crew Dragon for the first time. SpaceX Speaking of the Atlantic, the reusable Falcon 9 booster that launched Crew Dragon landed on the droneship Of Course I Still Love You drifting in the ocean, approximately 10 minutes after liftoff. As part of its Commercial Crew program, NASA handed contracts to both SpaceX and Boeing in 2014 to develop rockets that could send astronauts back to space. NASA hasn’t launched humans to space since 2011, when the Space Shuttle program ended. In the meantime, the agency has paid for spots on the Russian-built Soyuz spacecraft at a cost of over $80 million per seat. That makes Saturday’s success particularly important, helping chart a course for NASA to bring launches back to American soil and keep costs down.  “We want to make sure we keep our partnership with Russia, which has been very strong for a long period of time,” NASA Administrator Jim Bridenstine said before the flight. “But we also want to make sure we have our own capability to get back and forth to the International Space Station.” The Crew Dragon separates from the Falcon 9 in Earth’s shadow. SpaceX The Crew Dragon capsule is an enhanced version of SpaceX’s Dragon capsule, which has ferried cargo from Earth to the ISS on 16 previous occasions. This iteration can carry seven human passengers, which it’ll eventually shuttle to the ISS in low Earth orbit. Provided this demo mission proceeds as planned, the Crew Dragon will have to demonstrate its safety in one more “in-flight abort test,” scheduled for later this year. If it passes that test, SpaceX and NASA will finally be ready to make another giant leap, sending astronauts to the ISS from the US for the first time since 2011. last_img read more

first_imgThe global auto giant, General Motors, plans to invest $1 billion in India in the next few years to make the country its new global export hub, top executives of the company revealed.”GM cannot remain a global leader without making a serious investment towards expanding our presence in growth markets like India,” GM chief executive officer Mary Barra, told The Economic Times.GM’s India plans are a part of the company’s overall $5 billion investment earmarked towards the development of “a global family of Chevrolet vehicles” over the next few years, by partnering with Chinese automaker Shanghai Automotive Industry Corp (SAIC).In the past few years, the domestic automobile market has been witnessing sales of less than three million cars annually due to slowing demand. However, India is projected to emerge as the world’s third-largest passenger vehicle market by 2020, next to China and the US.The company will roll out 10 new locally-manufactured vehicles in India over the next five years, as it plans to double its market share in the country by 2020, said Stefan Jacoby, GM’s chief of international operations.GM occupied a market share of 1.8 percent by the end of 2014, selling 56,700 vehicles in the country.With Japanese and Korean automakers having a significant presence in the Indian automobile market, Western companies like GM, Ford Motor Co and Volkswagen AG are facing difficulties to improve their sales.”With this investment, we plan to tap India’s potential as a market and as a low-cost manufacturing base for the future,” Jacoby told Reuters.By making India as its export hub, GM also likely wants to ease some pressure on its operations in South Korea. South Korea has been its export hub for long, accounting for one-fifth of the automaker’s global output.”However, the Indian expansion doesn’t herald a gradual move away from GM’s use of South Korea as an export base,” Jacoby said.last_img read more

(AP Photo/Evan Vucci)President Donald Trump celebrated the National Day of Prayer by announcing a White House initiative that he said would underpin policies recognizing the “vital role” of religion in the country. “America is a nation of believers,” he said.Shortly before the Rose Garden event Thursday, Trump acknowledged reimbursing his personal attorney for hush money the lawyer paid to porn actress Stormy Daniels, who alleges a sexual encounter with Trump in 2006. The White House says Trump denies that accusation, and Trump had claimed no knowledge of the financial arrangement.Today, it was my great honor to celebrate the #NationalDayOfPrayer at the @WhiteHouse, in the Rose Garden! Proclamation: https://t.co/4jAxJnBJoq pic.twitter.com/AsWTfpu290— Donald J. Trump (@realDonaldTrump) May 3, 2018Trump tweeted before the faith event that the payments just before the 2016 election “had nothing to do with the campaign.”The president did not address the issue in his public remarks, focusing instead on the power of prayer as a centerpiece of American life.“Faith has shaped our families and it’s shaped our communities,” he said. “It’s inspired our commitment to charity and our defense of liberty, and faith has forged the identity and the destiny of this great nation that we all love.”Trump outlined steps by the administration to safeguard religious freedom and pledged to continue doing so.He signed an executive order creating a “White House Faith and Opportunity Initiative” that will, among other things, make recommendations on policies that affect faith-based and community programs. Trump said the new office will help ensure such groups have “equal access” to government money and the “equal right to exercise their deeply held beliefs.”“We take this step because we know, that in solving the many, many problems and our great challenges, faith is more powerful than government and nothing is more powerful than God,” Trump said.Members of the First Baptist Church of Sutherland Springs, Texas, where more than two dozen worshippers were killed in a November 2017 shooting, attended the event.As Trump mingled with guests on his way back to the Oval Office, a reporter shouted to the president, “Why are you changing your story on Stormy Daniels?” Someone in the audience shouted back, “Shame on you!” Sharelast_img read more

The Ruminant Genome Project reveals the secret lives of deer

The work was part of an overall project called, quite naturally, the Ruminant Genome Project. All three teams were made up of members from several institutions in China and a few other countries. All three groups have published their findings in the journal Science. Also, Dai Fei Elmer Ker and Yunzhi Peter Yang with the Chinese University of Hong Kong and Stanford University, respectively, have published a Perspective piece outlining the work by the three teams in the same journal issue.

Domesticated ruminants such as sheep and cows are important to humans. Others are important because of their unique physical characteristics. Deer antlers, for example, grow exceptionally quickly, and reindeer live in the Arctic without freezing or suffering depression due to long winter nights. In this new effort, all three teams sought to learn more about particular aspects of these unique mammals.In the first study, the researchers assembled the genomes of 44 ruminants covering all six members of the Ruminantia families. They created a phylogenetic tree for the group, which helped to clear up some of the mysteries in the family history. It also showed that the group as a whole suffered severe declines in population coinciding with humans migrating out of Africa.The work by the second team involved studying ruminant headgear—horns, antlers, pronghorns and ossicones. They found that despite their physical differences, the bony headgear shared many similarities. They also found that the reason deer antlers regenerate so quickly is because they exploit cancer-associated signaling paths. The deer also have tumor-suppressing genes that prevent tumors from growing in their antlers—information that could be useful in cancer research.

To find out, they studied the reindeer genome and discovered that reindeer have unique genes related to metabolizing vitamin D and circadian arrhythmicity, and also for female antler growth. And their unique digestive system helps them survive on limited plant growth. © 2019 Science X Networklast_img read more

Congress passes OPEN Government Data Act to make open data part of

first_img22nd December marked a win for U.S. government in terms of efficiency, accountability, and transparency of open data. Following the Senate vote held on 19th December, Congress passed the Foundations for Evidence-Based Policymaking (FEBP) Act (H.R. 4174, S. 2046). Title II of this package is the Open, Public, Electronic and Necessary (OPEN) Government Data Act, which requires all non-sensitive government data to be made available in open and machine-readable formats by default. The federal government possesses a huge amount of public data which should ideally be used to improve government services and promote private sector innovation. According to Data Coalition, “the open data proposal will mandate that federal agencies publish their information online, using machine-readable data formats”. What does the bill mandate? There are a number of practical things the bill will do, which should have real benefits for both citizens and federal organizations: Makes Federal data more accessible to the public, and requires all agencies to publish an inventory of all their “data assets” Encourages government organizations to use data to make decisions Ensuring better data governance by requiring Chief Data Officers in Federal agencies After some minor corrections made on Saturday, December 22nd, the Senate passed the resolution required to send the bill onwards to the president’s desk. There are two things which were amended in this act before passing it on to the president: The text was amended so that it only applied to CFO Act agencies, not the Federal Reserve or smaller agencies. There was acarve-out “for data that does not concern monetary policy,” which relates to the Federal Reserve, among others. Why is the open data proposal required? For many years, businesses, journalists, academics, civil society groups, and even other government agencies have relied on data that the federal government makes freely available in open formats online. However, while many federal government agencies publish open data, there has never been a law mandating the federal government to do so. The data available in a machine-readable format and catalogued online will help individuals, organizations, and other government offices to use it while preserving privacy and national security concerns. Open data has been an effective platform for innovation in the public sectors supporting significant economic value while increasing transparency, efficiency, and accountability in government operations. It has worked towards powering new tools and services to address some of the country’s most pressing economic and social challenges. Michele Jolin, CEO and co-founder of Results for America, said in a statement. “We commend Speaker Ryan, Senator Murray and their bipartisan colleagues in both chambers for advancing legislation that will help build evidence about the federally-funded practices, policies and programs that deliver the best outcomes. By ensuring that each federal agency has an evaluation officer, an evaluation policy and evidence-building plans, we can maximize the impact of public investments.” U.S Citizens also called this bill a big ‘milestone’ in the history of the country and accepted the news with vigor. You can read the entire backstory on what’s in the bill and how it was passed at E Pluribus Unum.

Swift 5 for Xcode 102 is here

first_imgApple announced Swift 5 for Xcode 10.2 yesterday. The latest Swift 5 update in Xcode 10.2 explores new features and changes to App thinning, Swift Language, Swift Standard Library, Swift Package Manager, and Swift Compiler. Swift is a popular general-purpose, compiled programming language developed by Apple Inc. for iOS, macOS, watchOS, tvOS, and beyond. Writing Swift code is interactive and its syntax is concise yet expressive. Swift code is safe and comprises all modern features. What’s new in Swift 5 for Xcode 10.2? In Xcode 10.2, the Swift command-line tools now require the Swift libraries in macOS. These libraries are included by default in Swift, starting with macOS Mojave 10.14.4. App Thinning Swift apps now no longer include dynamically linked libraries for the Swift standard library as well as the Swift SDK overlays in build variants for devices that run iOS 12.2, watchOS 5.2, and tvOS 12.2. This results in Swift apps getting smaller once they’re shipped in the App Store or thinned in an app archive for development distribution. Swift Language String literals in Swift 5 can be expressed with the help of enhanced delimiters. A string literal consisting of one or more number signs (#) before the opening quote considers backslashes and double-quote characters as literal. Also, Key paths can now support the identity keypath (\.self) i.e. a WritableKeyPath that refers to its entire input value. Swift Standard Library The standard library in Swift now consists of the Result enumeration with Result.success(_:) and Result.failure(_:) cases. Due to the addition of Standard Library, the Error protocol now conforms to itself and makes working with errors easier. The SIMD types and basic operators have now been defined in the standard library. Set and Dictionary also make use of a different hash seed now for each newly created instance. The DictionaryLiteral type has been renamed as KeyValuePairs in Swift 5. The String structure’s native encoding has been switched from UTF-16 to UTF-8. This improves the relative performance of String.UTF8View as compared to String.UTF16View. Swift Package Manager Targets can now declare the commonly used, target-specific build settings while using the Swift 5 Package.swift tools-version. A new dependency mirroring feature in Swift 5 enables the top-level packages to override dependency URLs. Package manager operations have become significantly faster for larger packages. Swift Compiler Size taken up by Swift metadata can be reduced now as the Convenience initializers defined in Swift only allocates an object ahead of time in case its calling a designated initializer defined in Objective-C. C types consisting of alignment greater than 16 bytes are no longer available in Swift. Swift 3 mode has been deprecated. Supported values for the -swift-version flag has become 4, 4.2, and 5.Default arguments can now be printed in SourceKit-generated interfaces for Swift modules. For more information, check out the official Swift 5 for Xcode 10.2 release notes.
