Spacewalking astronauts prepped the International Space Station on Friday for a new parking spot reserved for commercial crew capsules. The 250-mile-high complex already has one docking port in place for the SpaceX Crew Dragon and Boeing Starliner, which should start carrying up astronauts as early as next year. Friday's spacewalk set the stage for a second docking location. A new docking device will fly up late this year or early next. NASA astronaut Shane Kimbrough disconnected all four cables from an old docking port, using some extra force on one. He looped a spare tether around the balky cable and pulled, and off it came. "Nicely done, Shane," Mission Control radioed. On Sunday, flight controllers
In a story March 22 about dinosaur evolution, The Associated Press misspelled the name of the college of one expert. It is Macalester College, not Macalaster. A corrected version of the story is below: New idea shakes up dinosaur family tree for T. Rex and pals A new study dramatically rearranges the family tree of dinosaurs By SETH BORENSTEIN AP Science Writer WASHINGTON (AP) — Tyrannosaurus Rex and his buddies could be on the move as a new study proposes a massive shake-up of the dinosaur family tree. Scientists who took a deeper look at dinosaur fossils suggest a different evolutionary history for dinosaurs, moving theropods such as T. Rex to a new branch of the family tree and hinting at
Ever since the National Park Service's main Twitter account appeared to "go rogue" on President Donald Trump's inauguration day, people have been using the department and its various park-specific social media accounts as a rallying point in the anti-
A remarkable time-lapse video of the Aurora Australis has been captured from the window of a plane. The video was taken on a flight from Dunedin in New Zealand to see the remarkable light display. Also known as the Southern Lights, the Aurora Australis is the southern hemisphere counterpart of the Aurora Borealis, or Northern Lights. The trip was the first chartered flight from Dunedin to see the Southern Lights, according to the New Zealand Herald. The charter plane left Dunedin late Thursday and flew close to the Antarctic Circle to give the passengers an up-close look at the Aurora. Otago Museum Director Ian Griffin helped organize the flight so people could see the spectacular rivers of green
Brazil was scheduled to launch its first domestic defense and communications satellite Thursday as officials pledged to boost the country's space program and secure its information from foreign eavesdropping. The roughly 6.4-ton Geostationary Satellite Defense and Strategic Communications Satellite was made in France and its launch, delayed from Tuesday, would signal the first such project led by Brazil's private sector. Brazil has never before sent its own satellite into space and has instead leased eight foreign satellites, according to ZDNet.
The staff of Fortune and a panel of experts recently assembled our annual list of the World's Greatest Leaders. Visionary, ideologue, risk-taker: None of these shorthand labels quite capture who Elon Musk is. Tesla , the automaker and sustainable-energy company that acquired SolarCity in 2016, is Musk's pathway to a carbon--emissions-free world.
A plague of crop-destroying fall armyworm caterpillars has spread to East Africa where officials confirmed their presence for the first time in Uganda on Friday. An outbreak of the caterpillars in several southern African nations has already raised alarm with the UN Food and Agriculture Organisation warning they pose "a huge threat to food security". Uganda's Agriculture Minister Vincent Ssempijja said the presence of the innocuous looking but hugely destructive brown caterpillar had been confirmed in over 20 districts of the country.
Whether you're looking up at the Space Needle in Seattle or ogling the Empire State Building in New York, you might notice something strange this weekend. At 8:30pm local time on Saturday many prominent landmarks from coast to coast will suddenly go dark. What's going on? Don't fear a power outage or other electrical mishap. What you're witnessing is the tenth annual Earth Hour, organized by the World Wildlife Fund to raise awareness of climate change. The idea behind the event is simple -- by asking prominent buildings, schools, businesses, and even individual households to turn off all but essential lights, the event creates a rolling, worldwide visual representation of concern for climate
Currently being employed in the North Sea fjords in Norway, along with a select few lochs in Scotland, a smart underwater drone developed by Stingray Marine Solutions is designed to help deal with the problem of sea lice. Didn’t know that salmon had lice? “It’s not a problem that’s all that well known outside of the salmon farming industry in Norway,” John Breivik, general manager at Stingray, told Digital Trends. “In fact, it’s something that salmon farms are spending a lot of money to fight.
When the mighty orca breaks to the surface and exhales, the whale sprays an array of bacteria and fungi in its his breath, scientists said, some good, and some bad such as salmonella. The findings in a new study raises concerns about the potential role of infectious diseases as another major stress factor for the struggling population of endangered Puget Sound orcas. Those orcas' breath samples revealed microbes capable of causing diseases. Some were resistant to multiple antibiotics frequently used by people and animals, suggesting human waste contaminating the marine environment, according to a study published online Friday in the journal Scientific Reports. Scientists followed the whales as
"Noura's blood was not at the crime scene. And Jennifer's blood was not on Noura," says defense attorney Valerie Corder.
If you’ve ever pushed an upside-down cup into water, reached inside, and found it still empty, you’ve encountered a diving bell. It’s a simple concept: The water’s pressure forces the air, which has nowhere else to go, inside the “bell.” Once people realized that trapped air contains breathable oxygen, they took large pots, stuck their heads inside, and jumped into the nearest body of water. The first account of diving bells comes from Aristotle in the 4th century B.C.E. Legend has it Aristotle’s pupil Alexander the Great went on to build “a very fine barrel made entirely of white glass” and used it in the Siege of Tyre in 332 B.C.E. However, the facts of Alexander the Great’s adventures come mostly from depictions in fragments of ancient art and literature, which render him as a demigod who conquered the darkness and returned to the dry realm of historians and poets.
Miyako has invented an adhesive gel that collects flowers’ pollen grains and deposits them on other flowers upon contact. Miyako pilots the drone from flower to flower, rubbing the horsehair against pistils and stamens. Like the adhesive in a Post-It note, the gel is tacky but not sticky, so it releases some of the pollen grains on contact.
Ask Zhenan Bao why she went from designing batteries to creating synthetic, human-like skin and she'll give you a simple answer. Bao's 17-member Stanford team is developing is flexible, stretchable skin that can sense touch and temperature.
Elon Musk has chosen to go public with his disagreement on legislation signed by President Trump, claiming that it does nothing to help NASA or his company, SpaceX, get to Mars. Musk, who is part of President Trump's economic advisory team, has maintained a strategy of working with the president behind the scenes. Last month Musk claimed on Twitter he discussed both the administration's various travel bans and climate change in private meetings.
Cosmologist Stephen Hawking spoke in Hong Kong on Friday — only he wasn't actually present for the speech. The world-renowned physicist actually gave his speech live via hologram for the 90-minute lecture about his life and work. He was beamed in for
There's nothing quite like looking up and seeing the moon and stars on a clear night, but in the event of cloudy skies or bad weather, we've found the next best thing. Each lamp is made from upcycled garden globes and painted by hand. Maria ensures no two lamps are the same by using a variety of paints and layering techniques.
Virtual reality is pretty much the definition of an emerging technology, which means that different applications are being discovered seemingly every other day. While concepts like VR games are all well and great, however, a student at Nottingham Trent University in the U.K. has a potentially far more transformative use case: using virtual reality as a therapy tool. 24-year-old Gareth Walkom first developed a stutter when he was six years old.
California air regulators voted Friday to keep the state's tough vehicle emissions standards through 2025. The state Air Resources Board voted unanimously at a meeting in Riverside to continue with the standards for 2022 to 2025 after reaching a conclusion similar to one by the U.S. Environmental Protection Agency under the Obama administration. More recently, however, President Donald Trump said he wants to re-examine the rules governing gas mileage and set a uniform fuel mileage requirement for automakers in the U.S.
NASA tested part of the rocket that will likely take humans to Mars at the Stennis Space Center in Mississippi on March 23. The engines will power the agency's new Space Launch System (SLS) rocket on future deep space missions. This is the second RS-25 engine test for 2017 and the space agency has more planned. The engines will be part of the most powerful rocket in the world, according to NASA. Gary Benton, the product development manager for Stennis Space Center is in charge of testing of the rocket engines. "Those engines generate about 520,000 pounds of thrust each," Benton said, before the test fire of the engine. Benton says the SLS needs to be powerful because of the weight of the payload
The face of a British man who died about 700 years ago has been brought to life using reconstructive technology. The medieval man was buried along with hundreds of others in a graveyard underneath what is now the Old Divinity School building of St. John’s College at the University of Cambridge, in the United Kingdom. By studying his remains and piecing together his facial features and biological history, archeologists said they hope to understand the lives of anonymous poor people in the 13th century. “Most historical records are about well-off people and especially their financial and legal transactions,” study lead researcher John Robb, a professor of archaeology at the University of Cambridge, said
In 2014, I spoke with Gavin Pretor-Pinney, the founder of The Cloud Appreciation Society, about his quixotic mission: to get recognition for a new category of cloud called the “undulatus asperatus.” For years, individuals from across the world had been sending him pictures of the unusual formations, trying to figure out what they were. Yesterday, on World Meteorological Day — 9 years after the classification was first submitted — the World Meteorological Organization finally recognized Pretor-Pinney’s clouds in the updated version of the International Cloud Atlas, though the name has been tweaked to “asperitas.” They’re the first new addition to the Atlas in over half a century. Varying levels of illumination and thickness of cloud can lead to dramatic visual effects.” Asperitas clouds tend to be low-lying, and are caused by weather fronts that create undulating waves in the atmosphere.

The European Commission (EC) is reportedly mulling over new legislation that would ban a majority of insecticides used in fields across the continent. The phenomenon is known as colony collapse disorder, with most scientists in agreement that it is caused by the effects of plant-protecting chemicals, in addition to habitat loss and natural diseases. The most damaging pesticides in question are called neonicotinoids and according to leaked drafts of the plans, acquired by the Guardian, the EC is considering a blanket ban.
