As SpaceX's Elon Musk continues to track his red roadster's journey into deep space, he's also preparing to launch something far more practical. On Thursday, SpaceX will launch a pair of prototype satellites intended to form the basis for Starlink, a constellation of about 11,000 satellites that would beam broadband internet down to Earth. Thursday's launch - originally slated for Wednesday but put on hold because of "high altitude wind shear" - marks the first big step in Musk's plan for "rebuilding the internet in space," as he put it in 2015. In addition to competing with typical internet providers, Starlink could deliver connectivity to rural communities without the lag they're accustomed
Abdullahi Bego, a spokesman for the governor in Yobe state, said that authorities had no credible information that those missing from the village of Dapchi were taken by Boko Haram. Some witnesses, however, recalled seeing young girls being taken by the armed militants who also abducted 276 girls from the school in Chibok in April 2014. “I share the anguish of all the parents and guardians of the girls that remain unaccounted for,” Nigerian President Muhammadu Buhari tweeted Wednesday evening.
An ancient seal bearing a Hebrew script and recovered in Jerusalem may have belonged to the biblical prophet Isaiah. The clay seal dates back to the eighth century B.C. and was discovered in a Jerusalem excavation site, National Geographic reported.

Pence led the U.S. delegation to the opening ceremonies in Pyeongchang, South Korea, amid dramatic speculation that the United States and North Korea might finally sit down to talk. North Korea had sent athletes to compete at the games along with a delegation including its nominal head of state and Kim’s sister, Kim Yo Jong.
The arrival of plants on Earth changed the planet and its inhabitants in big ways, and a new study suggests they arrived far earlier than thought. University of Bristol researchers now say that land plants evolved from pond scum about 500 million years ago—a whopping 100 million years earlier than the history books tell us, per a release. The date we've long used is based on the fossil record, but fossils aren't so great when it comes to plants because they are far less likely to be preserved than, say, an animal with bones. Hoping to find the answer outside of the fossil record, study co-author Mark Puttick and a team of researchers looked for differences in the DNA of more than 100 plant and algal species to see when they diverged on the evolutionary scale, reports Science.
NASA studied "nuclear thermal propulsion systems" during the Cold War, but shelved the idea because it wasn't necessary. NASA has already hired a company to start working on a new NTP engine design. To accomplish what will be the greatest human spaceflight triumph since Apollo 11 - sending astronauts to Mars - NASA is looking to a blast from its nuclear past.
Hominins have lived in Western Spain’s Maltravieso Cave off and on for the last 180,000 years. At some point in those long millennia of habitation, some of them left behind hand stencils, dots and triangles, and animal figures painted in red on the stone walls, often deep in the dark recesses of the cave. The art they left behind offers some of the clearest evidence for a key moment in human evolution: the development of the ability to use symbols, like stick-figure animals on a cave wall or spoken language. Maltravieso, like La Pasiega in Northern Spain and Ardales Cave in the south, is a living cave, where water still flows, depositing carbonate minerals and shaping new rock formations. In
Kent Whitaker said he forgave his son Bart Whitaker, who is on death row and scheduled to be executed this week.
Dr. Ricardo Cruciani was taken into custody and will be arraigned in New York on multiple counts of rape and other sex crimes, police said. The former patient, Hillary Tullin, 45, called a sexual abuse hotline last year and reported that Cruciani had abused her between 2005 and 2012, authorities said. Tullin told The Associated Press on Tuesday that she testified before a grand jury about two weeks ago.
German judges Thursday pushed back a decision on whether German cities can ban old diesel cars to reduce air pollution, with potentially dramatic consequences for a key industry and transport policy in Europe's largest economy. The court "wants to deliberate very thoroughly" on the question, presiding judge Andreas Korbmacher said, adding that the ruling will be announced on Tuesday. While a decision from the Federal Administrative Court in Leipzig in favour of anti-pollution plaintiffs would not order any vehicles off the road, it could open the way for cities to do so in zones where the air is particularly contaminated by diesel exhausts.
Scientists have been asking this question for a long time — and thanks to the efforts of a self-taught astronomer from Argentina, they're one step closer to the answer. Victor Buso, a locksmith from the Argentine city of Rosario, managed to capture an image of a rare, momentary celestial phenomenon known as a "shock breakout." It's the moment that marks the transition from a star into a supernova — something that scientists have theorized about but never actually witnessed before. During a shock breakout, energy travels from the core of the star to its outer edge, creating a burst of light that directly precedes the star's explosion. Buso happened to be in his self-constructed observatory on Sept. 20, 2016, taking images of the night sky, when he noticed an extra blip of light in his pictures that didn't match up with any known celestial body.
Mental decline is a natural part of aging, but for about five percent of the elderly population, their wits stay sharp well into their 80’s and beyond. At an annual meeting of the American Association for the Advancement of Science in Austin, Texas last weekend, scientists from across the country came together to discuss their latest findings on the brains of super-agers, Science Alert reported. Super-agers are a small demographic of the elderly population that retain cognition on par with their far younger counterparts, sometimes up until the day that they die.
South Korea’s Unification Ministry says North Korea will send a high-level delegation led by Kim Yong Chol, a senior party official suspected of leading two deadly attacks on the South in 2010, to the closing ceremony of the Pyeongchang Winter Olympics. The eight-member delegation from North Korea is expected to stay for three days, the ministry announced Thursday. There was no announcement of any plan for the North Koreans to meet with a U.S. delegation to Sunday’s closing ceremony headed by Ivanka Trump, who was to arrive in Seoul on Friday.
One of those confronting the Florida senator at a CNN’s “Stand Up” town hall Wednesday night was Fred Guttenberg, whose 14-year-old daughter Jaime was killed on Feb. 14 with 16 others. Rubio was the lone Republican at the nationally broadcast gathering after Florida’s GOP Gov. Rick Scott and President Donald Trump declined invitations to appear at the event in Sunrise, Florida.
A study published this week in the Proceedings of the National Academy of Sciences used a new calculation method to determine where on Earths’ timeline plants initially appeared. To get a better idea of how far back plant life dates, the researchers used what they call a “molecular clock” method to analyze genetic changes over time and link them to their predecessors. Instead of relying on the fossil record alone, we used a ‘molecular clock’ approach to compare differences in the make-up of genes of living species – these relative genetic differences were then converted into ages by using the fossil ages as a loose framework,” Mark Puttick, co-lead author of the study, explains.
A European space probe has swung into position around Mars in preparation to analyze its atmosphere for possible signs of life. The European Space Agency said Wednesday its Trace Gas Orbiter successfully performed a delicate maneuver known as aerobraking that involved dipping into the red planet's upper atmosphere to slow the probe. The agency says the orbiter will start looking for trace gases such as methane, which can result from biological or geological activity, in April. It will also search for ice that could help future Mars landings. A NASA-made radio on board will also help relay signals from U.S. rovers on the surface back to Earth. Europe plans to land its own rover on Mars in 2021.
Two millennia ago, a small Greco-Roman temple in present-day Turkey awed and enthralled its residents. Was it the bloodthirsty will of Pluto, the god of the underworld? New research published on Feb. 12 in the journal Archaeological and Anthropological Sciences suggests a far earthlier explanation to the cave’s mystery: noxious carbon dioxide.
Something is causing the Yellowstone supervolcano to stir in its sleep. A swarm of some 200 earthquakes has been detected beneath the slumbering giant since February 8. The number of accompanying tremors is countless. Given the Earth-shattering power of this super volcano — which is capable of covering much of the United States under a thick blanket of lava and ash — it’s enough to raise some serious eyebrows. But none of the quakes have been huge: the biggest came in at just magnitude 2.9. This means the shake was just strong enough to be felt by some people. But there was no damage to any structures. And the underground movements that caused them are not likely to have had any impact on the
For years, European countries have commanded the most powerful passports in the world. Now, that title belongs to Asia. The Passport Index, which ranks nations based on travel freedom and visa requirements upon entering foreign countries, declared Tuesday that South Korea now wields the world’s most powerful passport, joining Asian city-state Singapore atop the rankings. South Korea and Singapore now outrank Germany’s passport, which in recent times topped the charts.
As many dog owners know to their cost, dogs often have a penchant for things that we find less than palatable. If it’s not counter or table surfing, it might be raiding the kitchen rubbish bin or snacking on rich pickings from the park, street or elsewhere. Occasionally, those rich pickings include poo, much to the disgust of many owners.
In the century preceding the death of Australia’s last known Tasmanian tiger, in Hobart in 1936, more than 750 specimens were collected and ended up in museums across the world. Most were bones and skins, but 13 were joeys in various stages of development, taken from their dead mothers’ pouches and preserved in ethanol. These “wet” specimens of Tasmanian tigers, or thylacines (Thylacinus cynocephalus), have proved to be a fantastic resource, not only allowing the sequencing of the creature’s genome – its entire DNA blueprint – which was published late last year, but now also allowing the creation of a series of 3D digital models of the young, from shortly following birth to first leaving the
Meanwhile, dozens of D.C.-area students have already staged a “die-in” outside of the White House — and more are in the works — and national school walkout days are planned for March and April. With the U.S. national voting age at 18, such actions are one of the few ways available for most high-school students to make their voices heard at the national political level. In fact, because the national voting age wasn’t lowered to 18 until 1971, it’s worth remembering that a fair amount of the most memorable civil rights and antiwar protests of the 1960s were staged by people who couldn’t vote yet.
No one is more familiar with the ups and downs of a competitive figure skater’s life than Mirai Nagasu, who is going for a medal this week at the 2018 Winter Olympic Games in PyeongChang, South Korea. Nagasu, a California native and only child of parents who immigrated to the U.S. from Japan, made her way up the national skating ranks, first as U.S. junior champion in 2007 and then as U.S. senior champion in 2008. In 2012 and 2013, she finished 7th at the U.S. nationals, and had spotty performances at international competitions.
New studies of ancient DNA have upended an idea which many researchers believed – that immigration was a relatively rare event in human history. Two new studies published in Nature this week bring the number of ancient humans whose DNA has been analysed to 1,334.
WASHINGTON — Vice President Mike Pence and members of the National Space Council approved a series of recommendations Feb. 21 that make modest, and expected, reforms to regulations of commercial space activities. The Council, meeting at the Kennedy Space Center in its second public session since being reestablished last June, approved a set of four recommendations intended to streamline licensing and other regulatory activities that both government officials and industry witnesses warned could slow down emerging space ventures. “But while American industry and technology have leaped towards the future, our government agencies too often have remained stuck in the past,” Pence said, citing regulatory
