Taliban attacks on Afghan forces cause 'heavy casualties': officials Posted: 11 Jul 2018 05:10 PM PDT Taliban attacks on Afghan security forces in the country's north have caused "heavy casualties", officials said Thursday, putting the number of soldiers killed as high as 40 in ongoing fighting. Militants using night-vision goggles launched simultaneous raids on several Afghan military bases and posts in Dashte Archi district in Kunduz province overnight, defence ministry spokesman Mohammad Radmanish and other Afghan security sources told AFP. "We have suffered casualties, the Taliban have also suffered casualties," Radmanish said. |

Tesla hits 200,000 cars, meaning lower tax credit for buyers Posted: 12 Jul 2018 08:41 AM PDT Under a major tax overhaul passed by the Republican-controlled U.S. Congress late last year, financial incentives in the way of tax credits that lower the cost of electric vehicles are available for the first 200,000 such vehicles sold by an automaker. The tax credit is then reduced by 50 percent every six months until it phases out. From Jan. 1 next year, the $7,500 tax credit will drop to $3,750 around mid-year, the Tesla website said. |

For the first time, an elusive ghost particle blasted from deep space is seen on Earth Posted: 12 Jul 2018 08:01 AM PDT Billions of years ago, a supermassive black hole feeding on gas and dust in the center of a galaxy spit out a subatomic ghost. That ghost particle — known as a neutrino — has quietly made its journey through the cosmos, across billions of light-years and arrived on Earth, where a large group of neutrino-hunting scientists were waiting to see it. A giant detector located in Antarctica caught sight of the neutrino sent into space by that feeding black hole, known as a blazar, marking the first detection of its kind in history. The groundbreaking new finding is detailed in two papers published in the journal Science Thursday. SEE ALSO: A woman sued NASA to keep a vial of moon dust. She might have made a huge mistake. Though scientists have detected the elusive particles on Earth, this detection marks the first time researchers have seen a neutrino that came to our world specifically from a powerful deep space source. Scientists have a compelling reason to call neutrinos "ghost particles." "They can travel through anything and only make their presence felt when they want to," Lindley Winslow, an MIT physicist that researches these mysterious particles, said in an interview. "10 billion neutrinos a second pass through your thumb," Darren Grant, a neutrino physicist at the University of Alberta, said, but you can't feel them. An artist's rendering of the IceCube lab, as an energy source approaches in the South Pole sky.Image: icecube/nsf"Their behavior is very much how people imagine a ghost — it doesn't leave any trace that it was there," Grant added. Scientists like Winslow and Grant suspected that highly-energized forms of these elusive particles, smaller than an atom, might be created by powerful forces in the distant cosmos and then thrown into space. But, although the particles are all around us — said Grant — they're incredibly difficult to detect. But now, the hunt for neutrinos is paying off. The ghost particle seen in the South Pole passed through a giant neutrino detector aptly named IceCube: It's a one-kilometer cube of ice some 2,500 meters (8,200 feet) under Antartica that has been outfitted with over 5,000 detection tubes. The idea was to build a massive detector, and hope that a deep space neutrino would eventually both collide with the sizeable icy instrument, and also make itself known. "We knew that these particles had to be coming from somewhere," said Winslow, who was not involved with this research. "The question was where. Now we know." For years, scientists have measured blasts of powerful energy from the deep cosmos, called galactic cosmic rays, hitting Earth's atmosphere. They assumed that something powerful in deep space was producing both these rays, and probably these highly-charged ghost particles, too. It now appears this is the case, and a distance blazar is responsible, Josh Frieman, a physicist at the Department of Energy's Fermi National Accelerator Laboratory who had no study involvement, said over email. Grant, a coauthor of the research, called the discovery nearly akin to scientists first seeing remnants of the Big Bang, when the universe was created, or the more recent detections of gravitational waves, ripples in time and space traversing the solar system. "Those of us that like neutrinos are pretty excited," said Winslow. "It's the infancy of a new field," noted Grant. Why finding ghost particles matter Much of our view and understanding of the universe comes from seeing light, said Winslow. Some of this includes things we can observe directly, like far-off galaxies. Another, new tool is the ability to detect gravitational waves, and then infer what powerful event could have created such momentous energy. And now, there's a third: neutrinos. "It's a whole other sense," said Winslow. "We've proven that neutrons are that third tool — to better understand the wonderful and weird things that are out there." And one these weird things is most certainly blazars: As gas and dust fall into a massive black hole at the center of a galaxy, they shoot some of this matter outwards, where it speeds out of both sides of the black hole in two vigorous jets. And sometimes, these jets happened to be aimed at Earth — or Earth happens to pass through one of these jets. When the neutrinos in those jets make it to our planet — and we're fortunate to detect one — they can help us understand what's out there in the void. An artist's rendering of a rather energetic blazar.Image: nasa"You can imagine being able to measure activities of the most violent processes of the universe in the neutrinos themselves," said Grant. The elusive particles only show themselves when there's another small particle quite close by, allowing them to interact with that particle. "That doesn't happen very often," said Grant. "If you live to be 80, one neutrino may interact with your body during your lifetime," he added. But when a detector does pick one up, scientists can then use traditional telescopes (which measure different types of light radiation) to peer back into space at the source — just like they did after detecting this neutrino. This allows them to confirm what's likely out there. In this case, it was a supermassive black hole, ejecting jets of energy. And once this blazar blasted out this neutrino, it traveled directly to our solar system, unperturbed by the powerful gravitational energies in space that bend light and distort energy. "The neutrino doesn't suffer from that," said Grant. "It travels unhindered from its source." It passes through turbulent space, then, just like a ghost passing calmly through bedroom walls.

Thai boys were passed "sleeping" through cave: rescue diver Posted: 11 Jul 2018 06:30 AM PDT The boys rescued from a Thai cave were passed "sleeping" on stretchers through the treacherous pathways, a former Thai Navy SEAL who was the last diver to leave the Tham Luang complex told AFP Wednesday. "Some of them were asleep, some of them were wiggling their fingers... (as if) groggy, but they were breathing," Commander Chaiyananta Peeranarong said, adding that doctors stationed along the dark corridors of the Tham Luang cave were constantly checking their condition and pulse. Thailand's junta chief told reporters on Tuesday that the group had been given a "minor tranquiliser" to help calm their nerves. |

US appeals judge's order allowing AT&T to buy Time Warner Posted: 12 Jul 2018 02:24 PM PDT The US Justice Department on Thursday appealed last month's ruling from a federal judge allowing AT&T to buy Time Warner in a mega-deal that could reshape the media-entertainment landscape. A notice of appeal was filed with a federal appeals court one month after Judge Richard Leon rejected the government's efforts to block the $85 billion deal following a weeks-long antitrust trial. The decision delivered a stinging rebuke to Donald Trump's administration in its first major antitrust court case. |

US asks UN to cut off oil products to North Korea Posted: 12 Jul 2018 12:19 PM PDT The United States asked the UN Security Council on Thursday to order an immediate halt to all deliveries of refined oil products to North Korea after accusing Pyongyang of violating sanctions with illegal imports of fuel, according to documents seen by AFP. A confidential US report sent to a UN sanctions committee estimated that at least 759,793 barrels of oil products had been delivered to North Korea between January 1 and May 30, well above the annual quota set in a UN resolution at 500,000 barrels. The illegal supplies were provided through ship-to-ship transfers at sea using North Korean tankers that have delivered their cargo at least 89 times, according to the report. |

Stocks, oil prices slide on trade war worries Posted: 11 Jul 2018 02:08 PM PDT By Hilary Russ NEW YORK (Reuters) - Concerns about an escalating U.S.-China trade war made markets topsy-turvy on Wednesday, with U.S. stocks breaking a four-session winning streak and Brent crude prices seeing their biggest one-day drop in two years. Metal prices also slumped after U.S. President Donald Trump's threat overnight of 10 percent tariffs on another $200 billion of Chinese goods dampened hopes that Washington will eventually step back from the escalating row. Trump has said he may ultimately target more than $500 billion worth of Chinese goods - roughly the total amount of U.S. imports from China last year. |
Israeli air strikes hit southwest Syria after drone 'infiltration' Posted: 11 Jul 2018 07:27 PM PDT Israel launched air strikes against three military posts in Syria Wednesday, its army said, after intercepting what it described as the incursion of an unarmed drone into its territory. The attack came hours after Israel's military fired a Patriot missile to knock down an unmanned aerial vehicle, or UAV, that strayed across Syria's ceasefire line with its neighbour. |
Elon Musk goaded into promising to fix Flint water problems Posted: 11 Jul 2018 11:54 PM PDT Elon Musk has been goaded into using his vast amount of wealth to fix Flint's water problems. Many people that argued that the billionaire could use his huge wealth more effectively, by paying for civil or charitable projects. Flint's water crisis came to public attention in 2014, when it was reported that the city's piping was leaking dangerous levels of lead into people's water supply. |
