That black hole you've seen everywhere now has a name.It's been christened Powehi — a Hawaiian phrase referring to an "embellished dark source of unending creation."The groundbreaking, first-ever photograph of a black hole was published around the world when it was unveiled on Wednesday, captivating viewers and providing the only direct visual evidence that these regions of spacetime exist.The responsibility of finding it a name fell to Larry Kimura, a Hawaiian language professor at the University of Hawaii at Hilo, who was approached by astronomers involved with the project. Two of the eight telescopes used to capture the photograph are located in Hawaii.Powehi was chosen for its roots in the Kumulipo, an 18th-century Hawaiian chant that describes a creation story.It puts together two terms from the chant: Po, meaning profound dark source of unending creation, and wehi (or wehiwehi) which is one of the several ways that po is described in the chant."It is awesome that we, as Hawaiians today, are able to connect to an identity from long ago, as chanted in the 2,102 lines of the Kumulipo, and bring forward this precious inheritance for our lives today," Kimura said in a statement."To have the privilege of giving a Hawaiian name to the very first scientific confirmation of a black hole is very meaningful to me and my Hawaiian lineage that comes from po," he added. "I hope we are able to continue naming future black holes from Hawaii astronomy according to the Kumulipo."Powehi was captured by the Event Horizon Telescope, a project that connected eight telescopes around the world.The supermassive black hole and its shadow, at the center of a galaxy known as M87, were photographed back in April 2017, but the results were only revealed on Wednesday."We have seen what we thought was unseeable," said Sheperd Doeleman, director of the Event Horizon Telescope Collaboration, unveiling the historic snap. "We have seen and taken a picture of a black hole."More than 200 researchers were involved in the project, and they had worked for more than a decade to capture the image. The project is named after the event horizon, the proposed boundary around a black hole that represents the point of no return where no light or radiation can escape.The telescope array collected 5,000 trillion bytes of data over two weeks, which was processed through supercomputers so that the scientists could retrieve the images."Powehi, as a name, is so perfect, because it provides real truths about the image of a black hole that we see," Jessica Dempsey of the James Clerk Maxwell Telescope, said in 2617

The number of foreign students coming to U.S. colleges and universities continued to fall last year, according to a new report, but the Trump administration says the drop should be blamed on high tuition costs and not students’ concerns over the nation’s political atmosphere.An annual report from the Institute of International Education found that the number of newly enrolled international students dipped by 1% in fall 2018 compared to the year before. It follows decreases of 7% and 3% in the previous two years, which were the first downturns in more than a decade.The downturn is a worry for universities that have come to rely on tuition from foreign students, who are typically charged higher rates. Some schools have blamed President Donald Trump’s rhetoric against immigrants for driving students away, but officials at the State Department, which pays for the annual report, dismissed the idea.Caroline Casagrande, deputy assistant secretary for academic programs at the department’s Bureau of Educational and Cultural Affairs, said students are deterred by the high cost to attend U.S. schools. She said the downturn is tied to students who were applying to college during the Obama administration, and that the numbers appear to be rebounding under Trump.“What we’ve seen today is a dramatically better picture compared to last year’s declines,” Casagrande said during a call with reporters. “The Trump administration has dedicated more resources than ever to international student mobility.”While fewer new students are coming, the study found that more are staying for professional training after they graduate. More than 220,000 were granted permission to stay for temporary work through a federal program, an increase of about 10% over fall 2017.China continued to send more students than any other country, followed by India and South Korea and Saudi Arabia. But booming years of growth from China have leveled off. The number of overall Chinese students in the country ticked up by less than 2%, and some campuses have seen major decreases in Chinese enrollment.The number of Chinese students at the University of Alabama has decreased by 43% over the past two years, to 266, according to the university’s annual enrollment report. At the University of Iowa and at Kansas State University, Chinese enrollment fell by about a third in that span.Declines from China have been attributed to several factors. Chinese students have reported difficulty getting U.S. visas amid a trade war between the two nations. Universities in Australia and Canada have worked harder to attract Chinese students. And some scholars say concerns over academic espionage have fueled anti-China sentiment on U.S. campuses.State Department officials said that they’re working to ease tensions and encourage Chinese students to study in the U.S. The department recently sent a delegation to China to promote academic exchange, and U.S. Ambassador Terry Branstad recently wrote an op-ed in a Chinese youth publication inviting students to study at U.S. schools.“The State Department has been working hard to make sure Chinese students know they’re welcome in the United States,” Casagrande said. “We want these Chinese students here.”The report also found that far fewer students are coming from Saudi Arabia, a shift that began in 2017 after the Gulf nation scaled back a scholarship program for global study. There were also dips in students coming from South Korea, Japan and Mexico.Meanwhile, the U.S. attracted growing numbers of students from Asia, Latin America and Africa. Numbers from Brazil and Bangladesh jumped 10% last year, the report found, while Nigeria ticked up 6%. Many universities have shifted their recruiting efforts to those areas in recent years as they look to offset losses from China.“More institutions are expanding their outreach in more regions,” said Mirka Martel, the head of research, evaluation and learning at the Institute of International Education, which is based in New York. “This growth demonstrates how attractive a U.S. education is for students around the world.”The academic subjects students come to study are also starting to shift. The number of students studying business, an area that has long been a draw for Chinese students, fell by 7% last year, the report found. Meanwhile, math and computer science saw a 9% increase and surpassed business as the No. 2 subject behind engineering.While the report focuses on data from 2018, it also included early findings for this year. Among more than 500 schools surveyed, the number of newly enrolled foreign students fell by 1% again, while the number of total international students fell by about 2%.___Collin Binkley can be reached on Twitter at 4748
Tense protests over the death of George Floyd and other police killings of black men grew Saturday from New York to Tulsa to Los Angeles. Police cars were set ablaze in several cities, and officers used tear gas and rubber bullets to contain demonstrators as the country lurched toward another long night of unrest after months of coronavirus lockdowns.In Philadelphia, 382
The "Fantastic Adventures" YouTube channel has racked up more than 250 million views, with its adorable cast of seven adopted children, silly topics and charmingly low-fi visual effects.Behind the scenes, though, the children told a different story. A welfare check last week found the home was a den of abuse in which their mother would withhold food and water for days at a time, pepper-spray them, force them to take ice baths and lock them in a barren closet, according to a statement of probable cause in Maricopa, Arizona."They stated they are disciplined in the manners above if they do not recall their lines or do not participate (in the videos) as they are directed to," the probable cause statement said."They further stated this is one of the reasons their mom took them out of school so they can keep filming their series and they mentioned they have not been in school for years."Police on Friday arrested their mother, Machelle Hobson, 48, on two counts of molestation of a child, seven counts of child abuse, five counts of child neglect and five counts of unlawful imprisonment. The Pinal County Sheriff's Office mistakenly listed her last name as Hackney but later provided her correct surname.Hobson's adult sons, Logan and Ryan Hackney, also were arrested Friday. They face seven charges each. They are accused of failing to report the abuse of a minor.Hobson's attorney, Richard Scherb, told CNN the state's case "is without merit."Her bond is set at 0,000 and her adult sons, Ryan and Logan Hackney, have been released from jail on their own recognizance, said Christy Wilcox, spokeswoman for the Pinal County Attorney.In the police report, Hobson said the closet in her room is never used for punishment, and she denied the accusations involving pepper spray and ice baths. She said the only forms of punishment she uses are having to stand in the corner, spankings and being grounded, the statement said.Ryan Hackney invoked his Miranda rights, but Logan Hackney spoke to police and said the children were locked in the closet, pepper-sprayed and forced to take ice baths, the statement said.What a welfare check foundHobson's YouTube channel posts a new video about once a week and boasts nearly 800,000 subscribers. With titles like "The FLOOR IS LAVA!" and "Escape The Babysitter!" each of the 10- to 15-minute episodes features the family of cute children in lightsaber battles, turning into superheroes or attempting to steal cookies.The statement of probable cause details a visit that welfare officers made to the home on March 13 after getting a tip from an adult daughter, who said one of the children said they were being abused.During the welfare check, one child was found in an unlocked closet, which has a locking mechanism, wearing only a pull-up diaper, the statement said, adding that the other six children appeared to be malnourished. It said they had pale complexions, dark rings under their eyes, were underweight and they said they were thirsty and hungry.According to the probable cause statement, one of the children drank three 16-ounce bottles of water within 20 minutes and said he had been pepper sprayed numerous times as punishment by his mother. Another child said she was extremely hungry and was given a bag of chips on the scene. However, she was afraid to eat the chips because she didn't want her mother to smell them on her breath, the statement said.The Department of Child Safety then removed the seven children from their mother's custody.A search of the home found two cans of pepper spray in the mother's room, and the closet in her bedroom had a deadbolt lock and a bare tile floor, the statement said.In follow-up interviews, one child told of how they were kept locked in a closet for days at a time with no food, water or restroom. They also were pepper sprayed all over their face and body, spanked, forced to take ice baths, and forced to stand in the corner with their arms raised for several hours at a time, the statement said."I either get beat with a hanger or belt" "or a brush," one child said, "or get pepper sprayed from head to toe," according to the statement.The child also said his mother would pinch the tip of his penis with her fingernails until it would bleed. Another child said she had been pepper sprayed on her vagina and recalled being in pain for four to five days, the statement said.YouTube confirmed the channel was demonetized once the company was made aware of the arrest. 4487
