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
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.

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.
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.
In a wave of demonstrations reaching from Arizona to Maine, students at dozens of U.S. high schools walked out of class Wednesday to protest gun violence and honor the victims of last week’s deadly shooting in Florida. The protests spread from school to school as students shared plans for their demonstrations over social media. Many lasted 17 minutes in honor of the 17 people killed at Marjory Stoneman Douglas High School in Parkland.
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.
Neither Cruciani nor his lawyer Mark L. Furman commented outside court. Cruciani changed from a beige jail uniform into a white shirt and black pants and got into a waiting car. One former patient, Hillary Tullin, 45, called a sexual abuse hotline last year and reported that Cruciani had abused her between 2005 and 2013, authorities said.
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.
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.
In global markets the price of cobalt, a mineral used in batteries for high-tech products from iPhones to Tesla electric cars, has nearly tripled to $81,500 a tonne in two years. In Kolwezi, a mining town in southeastern DRC, Chinese entrepreneurs dominate the middle section of the market, purchasing the raw cobalt from miners and selling it on for refining. Transactions in the buying houses depend on the purity of the ore.
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.
This week, students from Marjory Stoneman Douglas High School in Parkland, Fla. — where a 19-year-old gunman opened fire and killed 17 people one week ago — traveled roughly 450 miles northwest to state capital Tallahassee to make their voices heard. Nearly 100 students from Marjory Stoneman Douglas High School made the trek, which was organized in part by 17-year-old high school junior Jaclyn Corin, along with other students who are part of the Never Again movement. According to the Naples Daily News, the students split into small groups to meet with both Democratic and Republican lawmakers.
Researchers from Florida Polytechnic University are developing a "happy suit" that they say will protect astronauts from the psychologically harrowing effects of space travel. The technology's network of wireless sensors would respond to the wearer's vitals by recalibrating his or her environment in real time. These adjustments could include changes in temperature, light color, light intensity and oxygen levels, Arman Sargolzaei, an assistant professor of electrical engineering at the school, said in a statement. "It's vital for astronauts to be mentally healthy during missions and right now there's no active, real-time solution to help them when they feel stressed or anxious," said Sargolzaei,
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.
Last year, Emma Gonzalez was leading Marjory Stoneman Douglas High School’s Gay Straight Alliance and working on a science project that launched a camera into space. Cameron Kasky played Motel (“the ‘miracle of miracles’ guy”) in the school’s production of Fiddler on the Roof. As the students’ movement gains visibility, they have faced backlash from bots and trolls who spread conspiracy theories about them and accuse them of being “crisis actors.” But the kids just laugh it off.
Wayne LaPierre, the National Rifle Association’s Executive Vice President, told the Conservative Political Action Conference Thursday that politicians and the media are exploiting the Florida school shooting to expand gun control and ultimately abolish the second amendment, striking a defiant tone in his first public remarks since the mass shooting that killed 17 people and reignited the gun control debate in the U.S. to a fever pitch. “They hate the NRA,” LaPierre said.”The elites don’t care one wit about school children.

Cave paintings and artifacts like painted seashells have long been regarded as the work of early modern humans, who were thought to have more advanced cognitive abilities than Neanderthals. Dating cave paintings can be a difficult process, and unreliable techniques never allowed for the possibility that these could be the work of Neanderthals. Until now, that is. A new technique called Uranium-Thorium dating is less destructive, is more accurate and can go back further in time than other methods. U-Th dating looks at the deposits of carbonate on top of the paint, which contain traces of uranium and thorium that indicate when those deposits formed. That allows the researchers to determine an age
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 Feb. 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 60-billion-cubic-mile
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.
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.
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.
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.
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.
