Cape Canaveral, Aug 31 (AP/UNB) — Astronauts scrambled Thursday to patch a tiny hole in a Russian capsule that was allowing air to leak from the International Space Station.
NASA and Russian space officials stressed the six astronauts were in no danger.
The leak was detected Wednesday night — possibly from a micrometeorite strike — when it caused a small drop in cabin pressure. It was traced to a hole about 2 millimeters (less than one-tenth of an inch) across in a Soyuz capsule docked at the space station.
Thursday morning, the crew taped over the hole, slowing the leak. Later, the two Russian spacemen put sealant on a cloth and stuck it over the area, while their colleagues took photos for engineers on the ground. Flight controllers, meanwhile, monitored the cabin pressure while working to come up with a better long-term solution.
Mission Control outside Moscow told the astronauts to let the sealant dry overnight and that more leak checks would be conducted Friday. The makeshift repairs seem to have stabilized the situation, at least for now, officials said. Earlier, flight controllers tapped into the oxygen supply of a Russian cargo capsule to partially replenish the atmosphere in the station.
The leaking Soyuz — one of two up there — arrived at the orbiting lab in June with three astronauts. It's their ride home, too, come December, and also serves as a lifeboat in case of an emergency. A NASA spokesman said it was premature to speculate on whether the three might have to return to Earth early if the leak, even as small as it is, cannot be stopped.
The hole is located in the upper, spherical section of the Soyuz, which does not return to Earth, according to NASA.
The 250-mile-high outpost is home to three Americans, two Russians and one German. Orbital debris is a constant threat, even the tiniest specks.
Washington, Aug 30 (AP/UNB) — Top executives at Facebook and Twitter are set to appear before Congress next week as lawmakers continue probing efforts by Russia and other countries to influence social media platforms and meddle in U.S. elections.
Twitter CEO Jack Dorsey and Facebook's chief operating officer Sheryl Sandberg are scheduled to testify Wednesday before the Senate Intelligence Committee.
Larry Page, CEO of Google's parent company Alphabet, also has been invited to the hearing. Lawmakers so far have rejected Google's offer to send a lower-level executive, and the search giant has not committed to sending Page to testify.
The committee is investigating Russia's interference in the 2016 election and connections to President Donald Trump's campaign.
Dorsey is set to testify later Wednesday before the House Energy and Commerce Committee.
Dhaka, Aug 30 (UNB) - Robi- 10 Minute School, (www.robi10minuteschool.com) is providing special support on general knowledge for the students who are preparing for admission test for Dhaka University’s Gha unit.
The online school is taking separate classes on Bangladesh and international affairs, said a press release.

Robi-10 Minute School believes that the students need to also focus on current affairs issues to do well in the general knowledge part of the admission test. In this regard, students are advised to stay updated on world affairs that took place within at least four months of the exam.
Robi- 10 Minute School’s website has special classes on these issues in audio-visual format.
In addition, Robi- 10 Minute School also contains the general knowledge questions that featured in the admission test for Dhaka University’s Gha unit in previous years. Students may also visit www.robi10minuteschool.com to practice those questions.
General knowledge makes up the largest portion of the marks allotted in the admission test for Dhaka University’s Gha unit. 25 questions are allocated for Bangladesh related general knowledge and 25 questions are allocated for the international affairs issues. In total 50 questions provide 60 marks. Robi- 10 Minute School provides the complete solution to the admission seekers in this regard.
Beijing, Aug 29 (AP/UNB) — More than a dozen human rights groups have sent a letter to Google urging the company not to offer censored internet search services in China.
The joint letter dated Tuesday calls on CEO Sundar Pichai to explain what Google is doing to safeguard users from the Chinese government's censorship and surveillance.
That follows a letter earlier this month signed by more than a thousand Google employees protesting the company's secretive plan to build a search engine that would comply with Chinese censorship, and calling on executives to review ethics and transparency at the company.
Google had previously complied with censorship controls starting in 2006 as it sought a toehold in the booming Chinese economy. But it faced unrelenting pressure from human rights groups and some shareholders to leave.
San Francisco, Aug 28 (AP/UNB) — Uber is teaming up with Toyota to build self-driving cars for its ride-hailing service after its efforts to do it alone were derailed by a fatal collision and allegations of high-tech theft.
Toyota, based in Japan, is also investing $500 million in Uber as part of the alliance announced Monday.
The deal aims to combine the best features from the two companies' work on autonomous technology into cars that will be picking up Uber's customers by 2021.
By the time that happens, Uber hopes to have completed an initial public offering of stock that will enrich a list of early investors that now includes Toyota. Those investors have been pouring billions of dollars into Uber's revolutionary ride-hailing service that still hasn't proven it can make money since its inception nearly a decade ago.
Uber is counting on self-driving cars to help it turn the financial corner by reducing the need to pay human drivers who arrive to pick up passengers in private vehicles summoned through a smartphone app.
By expanding into autonomous vehicles, Uber also hopes to ward off a looming competitive threat from another early investor, Google and its self-driving car spin-off Waymo, which is poised to launch its own ride-hailing service in Arizona before the end of this year.
"Our goal is to deploy the world's safest self-driving cars on the Uber network, and this agreement is another significant step towards making that a reality," said Uber CEO Dara Khosrowshahi.
Meanwhile, Toyota is trying to evolve from a pure automobile maker into a "mobility company," as are many of its industry peers, including General Motors and Ford in the U.S. That crusade has prodded decades-old automakers such as Toyota and GM to invest in and partner with technology companies working on self-driving cars while also opening up their own research hubs in Silicon Valley.
Besides allowing them to lean on each other's respective strengths, Toyota's deal with San Francisco-based Uber also will help the two companies spread out the cost of designing and building the complex systems, which use computers, cameras, radar and laser sensors to guide the self-driving vehicles.
Uber is turning to Toyota for help in autonomous vehicles five months after one of its self-driving cars ran over and killed a pedestrian crossing a dark street in Tempe, Arizona.
The March 18 crash prompted Uber to temporarily suspend its work on its self-driving car program while conducting a safety evaluation.
Authorities determined the sensors on Uber's self-driving car sensors spotted the pedestrian, 49-year-old Elaine Herzberg, but the vehicle's automatic-braking function had been disabled in favor of a human backup driver. Tempe police said the driver was distracted and streaming a television show before the crash.
Uber had little choice but to find a self-driving car partner after the collision that killed Herzberg, said Navigant Research analyst Sam Abuelsamid.
"It's going to be tough for them to build consumer trust in whatever it is they're developing," he said. "I think that people will have a lot more trust in Toyota to do this the right way, to take due care and make sure everything is properly tested and evaluated."
Uber's expansion into self-driving cars suffered another setback last year after Waymo accused it of stealing its technology in an elaborate scheme . The case went through one week of a high-profile trial before Uber agreed to pay Waymo $245 million in stock to settle the allegations without acknowledging wrongdoing.
