The massive new ship measures 173 metres in length and has two nuclear reactors with the propulsion power of 60 megawatts. Organisers at the launching ceremony in Saint-Petersburg's Baltic Shipyard broke a bottle of champagne against the vessel's massive hull. Nuclear energy ensures Russia's undisputed leadership in the far north, said Vyacheslav Ruksha, head of Atomflot state company which manages Russia's nuclear icebreakers. Only with nuclear icebreakers can our country fully unveil all possibilities and advantages of the Northern Passage to the world, he said.
In a large-scale experiment designed to analyze the spread of information on social networks, Ferrara and a team from the Technical University of Denmark deployed a network of algorithm-driven Twitter accounts, or social bots, programmed to spread positive messages on Twitter. We found that bots can be used to run interventions on social media that trigger or foster good behaviors, says Ferrara, whose previous research focused on the proliferation of bots in the election campaign.
Facebook on Friday reversed course on a plan to issue a new non-voting class of shares, avoiding a public trial in a suit filed by investors in the huge social network. He and his wife still plan to give away 99 percent of their Facebook shares during their lifetimes, and are even accelerating the process. Zuckerberg expected to sell 35 to 75 million Facebook shares during the coming 18 months to fund philanthropic work in education, science, and advocacy through the Chan Zuckerberg initiative.
A spy satellite for the US National Reconnaissance Office has been launched from Vandenberg Air Force Base in California. All systems were going well when the launch webcast concluded about three minutes into the flight. The launch was expected to be visible across a wide area of California, weather permitting. National Reconnaissance Office satellites gather intelligence information for US national security and an array of other purposes including assessing impacts of natural disasters.
Screeching to see visitors on the forested Chimpanzee Island in Ivory Coast, Ponso is the last, lonely survivor of a colony of 20 apes who mysteriously died or vanished. Chimpanzee Island adjoins the village of Grand-Lahou in the Bandaman estuary, an outlying reach of tropical forest about 100 kilometres from the commercial capital, Abidjan. Only Ponso remains of the group of chimpanzees relocated to the tiny island from Liberia in 1983 by a research laboratory for medical tests.
Authorities said two people also died in the quake in the southern state of Oaxaca, where the epicenter was located. In a jittery Mexico City, the quake made buildings sway, but some didn't notice. Far, 69 people have been pulled alive from the rubble in Mexico City, according to authorities. The latest death toll stands at 305, of which more than half-167 fatalities-were in Mexico City.
With a handful of US technology giants growing more powerful and dominant, debate is intensifying on whether big tech's growth is healthy or not. Along with stalwarts like Microsoft and rising stars like Netflix, the tech firms exercise enormous control over what people see and how they live. Increasingly, policymakers and others have begun to consider breaking up or regulating the biggest technology companies, although imminent action appears unlikely.
A Dartmouth-led study has demonstrated how the latest aerial thermal imagery is transforming archaeology due to advancements in technology. Archaeologists have long used thermal infrared images to locate buried architecture and other cultural landscape elements. The thermal infrared radiation associated with such archaeological features depends on several variables, including the make-up of the soil, its moisture content and vegetation cover. Now, aerial thermography makes it possible to gather field survey data across a much larger area in much less time.
It may not be surprising that an aquatic desert turtle faces long odds in life, but environmentalists and biologists still welcomed this week's endangered species designation for the Sonoyta mud turtle. The Sonoyta mud turtle is clearly in danger of extinction, Steve Spangle, a field supervisor with Fish and Wildlife's Arizona Ecological Services, said in a release announcing the listing. Iverson said that the turtle is as safe as it can be, given the circumstances, and that Mexico is where the problem is.
London's mayor said Saturday that people angry about the decision by transit authorities to strip Uber of its license to operate in the city should blame the ride-hailing company itself. I have every sympathy with Uber drivers and customers affected by this decision, but their anger really should be directed at Uber, Mayor Sadiq Khan said. The city's transportation agency, Transport for London, said Friday that it would not renew Uber's license when it expires Sept. 30, citing a lack of corporate responsibility.
In her online world, she is Lady Beast, deftly operating her green monster Blanka in dizzying hand-to-hand streetfighting combat on the global professional gaming circuit. When I started going to game arcades, I was playing fighting games, which meant it's all men around you. As they are so small in number, female gamers stand out and attract attention, not always positive. 'Street Fighter V' Momochi started gaming at a young age, playing Donkey Kong and other video games with her brother.
They say they have only begun using new satellite and laser-imaging tools to document the area and that more discoveries are possible. A world heritage site, Chaco and its outlying archaeological remnants have become the focus of the fight over expanded drilling. They have asked for the federal government to make permanent a 10-mile buffer zone around Chaco park. GB Cornucopia, a ranger at Chaco park, also raised concerns about light pollution from oil and gas operations.
The federal government on Friday told election officials in 21 states that hackers targeted their systems before last year's presidential election. The notification came roughly a year after US Department of Homeland Security officials first said states were targeted by hacking efforts possibly connected to Russia. The AP contacted every state election office to determine which ones had been informed that their election systems had been targeted. The Wisconsin Election Commission, for example, said the state's systems were targeted by Russian government cyber actors.
A number of brain states raise the risk of acting out violently, and the evidence so far, while incomplete, suggests that CTE may be one of them. In a recent study of dementia patients, Swedish researchers found that 97 of 281 dementia patients had a history of aggression. Over the past decade, many courts have been reluctant to admit brain scans as exculpatory evidence.
Amazon wants to deliver more burritos and hamburgers to your doorstep. The e-commerce giant said Friday that it is partnering with online ordering platform Olo, in a deal that could boost the number of restaurant chains on its Amazon Restaurants delivery service. Under the deal, restaurants that use Olo can list their menus on Amazon Restaurants. The restaurants would prepare orders and Amazon would provide a worker to deliver it to the customer.
Surface runoff and leaching are two major transportation pathways for nitrate to reach and pollute water. Due to its mobility and water solubility, nitrate has long been recognized as a widespread water pollutant. What we found is that no-till is not sufficient to improve water quality, said Lixin Wang, an assistant professor and corresponding author of the paper. It reduces soil erosion by avoiding tilling year after year, which leads to soil getting washed away into lakes and rivers.
This could be your chance to make Sputnik beep again. It was little more than an aluminum beach ball with a radio transmitter that sent out a regular series of radio beeps, but it expanded the Cold War to outer space, shook up American technological smugness and probably helped John Kennedy get elected president in 1960.
It just turns out they're built by octopuses. In other words, it's basically an octopus city, which biologists are calling Octlantis, according to The Guardian. In 2009, scientists discovered a similar site - also in Jervis Bay - dubbed Octopolis, but it was widely considered to be an anomaly. The existence of Octlantis, though, suggests that groups of octopuses living together are more common than people thought.
More than half of all American teenagers are getting vaccinated against human papillomavirus, and the rate is rising over time, according to a new report from the Centers for Disease Control and Prevention. Sixty percent of adolescents received one or more doses of the HPV vaccine in 2016, an increase of 4 percentage points from 2015, researchers found. About a decade ago, the figure was less than 30 percent.
Now engineers at MIT have devised a framework for identifying key patterns that precede an extreme event. Currently there is no method to explain when these extreme events occur, says Themistoklis Sapsis, associate professor of mechanical and ocean engineering at MIT. We have applied this framework to turbulent fluid flows, which are the Holy Grail of extreme events. If we can predict the occurrence of these extreme events, hopefully we can apply some control strategies to avoid them.
