It's hard work hauling water into space. Having water on the moon would make future space missions a lot more efficient — if we can get to that water.
Even if we meet our most ambitious climate goal — keeping global temperatures within a strict 1.5 degrees Celsius (or 2.7 degree Fahrenheit) of their preindustrial levels — there will still be consequences, scientists say. And they’ll last for years after we stop emitting carbon dioxide into the atmosphere. New research suggests that extreme El Niño events — which can cause intense rainfall, flooding and other severe weather events in certain parts of the world — will occur more and more often as long as humans continue producing greenhouse gas emissions. And even if we’re able to stabilize the global climate at the 1.5-degree threshold, the study concludes, these events will continue to increase
A man accused of accidentally sparking a massive Utah wildfire that forced some 1,500 people from their homes last month and cost about $34 million to fight was charged Tuesday. Iron County prosecutor Scott Garrett told The Associated Press that his office charged Robert Ray Lyman, 60, with two misdemeanors. Garrett declined further comment, but authorities have said the fire started when a man set a pile of weeds on fire and it raged out of control near a cabin in the ski town of Brian Head on June 17.
For almost a half-century there’s been a clear speed limit on most commercial air travel: 660 miles per hour, the rate at which a typical-size plane traveling at 30,000 feet breaks the sound barrier and creates a 30-mile-wide, continuous sonic boom. The ground-level disturbances that result—shattered windows, cracked plaster, maddened farm animals—have kept supersonic travel mostly off-limits since 1973, when the Federal Aviation Administration banned its use over U.S. soil. That may be changing. In August, NASA says, it will begin taking bids for construction of a demo model of a plane able to reduce the sonic boom to something like the hum you’d hear inside a Mercedes-Benz on the interstate.
Ever since Environmental Protection Agency (EPA) administrator Scott Pruitt and other Trump administration officials raised the idea of putting climate science up for debate, it's been an open question as to where the participants who doubt mainstream climate science would come from. Now that is becoming clearer, and the answer is sure to further convince many that this entire exercise is a set up to discredit some of the most basic, rigorously studied climate science conclusions. SEE ALSO: EPA chief wants his useless climate change 'debate' televised, and I need a drink The Washington Examiner reported on Monday that the EPA has reached out to the controversial Heartland Institute for help
Fifty years ago humans walked on the moon. Twenty years ago humans started living in orbit for months at a time. Where will we go next? For NASA, one of the most promising proposals is to build a space habitat for astronauts that will orbit the moon. To help NASA achieve such a complicated endeavor, Lockheed Martin, one of the contractors for the habitat, is building a full-scale prototype out of an old cargo container designed to fly on the Space Shuttle. An orbiting moon station has a number of unique challenges that the International Space Station doesn't have. Chief among them is that a moon habitat would be much farther away. The crew of such a station would have to operate much more independently
Lemons were the acai bowls of the ancient Romans — prized by the privileged because they were rare, and treasured for their healing powers. In fact, this coveted fruit, as well as the citron, were the only citrus fruits known in the ancient Mediterranean — it took centuries for other fruits, such as oranges, limes and pomelos to spread westward from their native Southeast Asia, a new study finds. However, the citrus fruits that followed in later years weren't as exclusive as lemons and citrons, said the study's lead researcher, Dafna Langgut, an archaeobotanist at Tel Aviv University in Israel.
Elon Musk has slammed Facebook CEO Mark Zuckerberg’s “limited” understanding of artificial intelligence. Musk was responding to Twitter user Darren Cunningham, who shared an article with recent comments from Zuckerberg.
On Monday August 21, a solar eclipse will cut across the entire United States. And wherever you are, you will be able to see it. Even though the “totality” — the area where the sun is completely blocked out by the moon — is only 70 miles wide, the whole country (even Alaska and Hawaii) will experience a partial eclipse. This is what you’ll see, and the time you’ll see it, in your zip code. We recommend punching in a few different ones to see how the eclipse experience will vary across the country. Salem, Oregon (97301), is going to see a total eclipse. Downtown Los Angeles (90012) will see 62 percent of the sun blocked at the peak. In Lake Charles, Louisiana (70601), it’ll be 71 percent. The
There’s just one problem with the theory of the ‘deadly’ Triangle, Australian science communicator Karl Kruszelnicki revealed this week in an interview – it’s actually no more deadly than any other stretch of sea. ‘According to Lloyds of London and the US coast guard, the number of planes that go missing in the Bermuda Triangle is the same as anywhere in the world on a percentage basis,’Dr Kruszelnicki said.
At least 10,000 people, including thousands of holidaymakers, were evacuated overnight after a new wildfire broke out in southern France, which was already battling massive blazes, authorities said Wednesday. The new fire broke out a day after France asked for Europe's help to tackle the flames already raging in several spots on the tinder-dry south, including near the popular resort of Saint-Tropez. Firefighters are also battling fires on the French Mediterranean island of Corsica and in Portugal.
Girl Scouts from tiny Daisies to teen Ambassadors may earn 23 new badges focused on science, technology, engineering and math. The effort takes a progressive approach to STEM and also nudges girls to become citizen scientists using the great outdoors as their laboratory. Among the new badges are those that introduce kindergarten and first graders to the world of robots and engineering.
It's pretty dark in Antarctica right now, but that didn't stop NASA's Landsat 8 satellite from using its thermal infrared imaging powers to get a good look at the spectacular iceberg that broke away earlier this month. The floating ice chunk is one of the largest on record. The iceberg, saddled with the uneventful name A-68, separated from the Larsen C ice shelf and immediately got compared in size to the US state of Delaware and the amount of water in Lake Ontario. The Landsat view is a composite created from images taken on July 14 and July 21 by the satellite's Thermal Infrared Sensor. The satellite has monitored the natural phenomenon over the course of its evolution from a thin crack to
The US Navy has taken another step closer to swapping powder for electrons with the Office of Naval Research (ONR) announcing that its electromagnetic railgun has moved out of the laboratory. At the 2017 Naval Future Force Science and Technology Expo in Washington DC, an ONR spokesman revealed that the weapon is ready for field demonstrations at the Naval Surface Warfare Center Dahlgren Division's new railgun Rep-Rate Test Site at Terminal Range. The ElectroMagnetic RailGun (EMRG) is one of a new generation of hypersonic weapons being developed by the major powers. With muzzle velocities of over Mach 6 (3,970 kts, 4,570 mph, 7,350 km/h) and a range of over 100 nm (115 mi, 185 km), the projectiles
NASA is giving Lockheed Martin the permission to go where no company has gone before. To deep space — using recycled material. As part of its NextSTEP program, NASA will allow Lockheed Martin to use repurposed pieces of space shuttle for the habitat that could be used on Mars missions. First, the company will build a full-scale prototype and then start testing the technologies at NASA's Kennedy Space Center. In addition to using recycled material from the container space shuttles, it will also rely on virtual and augmented reality to design the prototype. "It is easy to take things for granted when you are living at home, but the recently selected astronauts will face unique challenges," said
Scientists have long been able to make specific changes in DNA, but some researchers are now pursuing the more radical route of building an organism’s DNA from scratch, a stepping stone to tackling human DNA. (July 26)
Two of Silicon Valley's most powerful figures are officially in a war of words. To recap: During a Facebook Live Q&A session on Sunday, Mark Zuckerberg criticized Elon Musk for saying artificial intelligence is "the biggest threat we face as a civilization." "I think people who are naysayers and try to drum up these doomsday scenarios--I don't understand it," the Facebook CEO said. "It's really negative, and in some ways I think it's pretty irresponsible." Now, Musk has fired back. On Tuesday, the Tesla and SpaceX founder tweeted a dig at Zuckerberg. Musk has extensive experience with A.I. technology through his business ventures: Tesla's self-driving vehicles rely heavily on artificial intelligence,
Washing down your bacon cheeseburger with a big, cold soda may trigger the body to store more fat than it would if you drank something without sugar, a new small study finds. When the people in the study added a sugary drink to a protein-rich meal, their bodies’ fat-burning ability decreased by 8 percent on average, the researchers found. In addition, the sugary drinks also appeared to increase their food cravings after the meal.
Red imported fire ants are regarded as pests throughout the Southern US, where they’ve thrived since they were inadvertently introduced from South America in the 1930s or ’40s. But at a Georgia Tech laboratory, the question at hand is not how to get rid of fire ants, but rather what we can learn from them. These ants build large structures with their bodies without a leader directing the colony. Those ant aggregations display some interesting material properties, which is why they’ve attracted the attention of mechanical engineers. Check out the video above to learn more, or watch on our YouTube channel.
The number of rhinos killed for their horns by poachers in South Africa dipped slightly in the first half of this year, but more than 500 were still slaughtered, the government announced Monday. South Africa is battling a scourge of rhino poaching fuelled by insatiable demand for their horn in Asia. Most of the demand emanates from China and Vietnam, where the horn is coveted as a traditional medicine, an aphrodisiac or as a status symbol.
“The likelihood of a door being ripped open by a human being is very low,” said Dennis Tajer, a pilot who’s been working for American Airlines for 25 years. “The higher interior pressurization actually seals the door to the frame,” said Douglas Moss, a pilot for United Airlines for 20 years.
The archaeologists eventually plan to excavate the new tomb, which is located near the tomb of the pharaoh Ay (1327-1323 B.C.) in Egypt's Valley of the Kings, Hawass told Live Science. "We are sure there is a tomb there, but we do not know for sure to whom it belongs," Hawass told Live Science in an email. On July 7, National Geographic Italia published an article in Italian suggesting that a team led by Hawass had found a new tomb in the Valley of the Kings, and Hawass confirmed that discovery to Live Science.
As investors, our natural impulse when faced with arresting news or growing uncertainty is to react. There is an abundance of great research on this topic, however one of the most relevant was a study by Barber & Odean which shows a clear link between portfolio turnover and the results generated by individual investors.
NASA is working to bring supersonic speeds to commercial flights in the United States, which could cut travel times in half. The key? Keeping the noise down. The agency has a design for a new supersonic jet meant to reduce the effects of sonic booms to a much less noticeable "quiet thump." It hopes to take bids from aircraft manufacturers starting in August to build a demo model, according to a Bloomberg report. Sonic booms typically occur once a plane pushes beyond 660 mph and breaks the sound barrier, causing disturbances all the way down on the ground below. The phenomenon was one of the major reasons the super-fast transport was largely banned over U.S. soil back in 1973. NASA's jet design,
With the world facing increased warming, melting ice caps, rising sea levels, intense weather events and other global disasters, scientists are exploring ways to re-engineer the planet to counter the effects of global warming. Earth's surface has warmed, on average over land and sea, 1.53 degreesFahrenheit (0.85 degrees Celsius) since 1880, according to the Intergovernmental Panel on Climate Change, an international organization created by the United Nations to evaluate the state of climate change science. In the most recent issue of the journal Science, published online Thursday (July 20), two researchers provided perspective on two geoengineering methods that could reduce the so-called greenhouse effect, under which gases and clouds in Earth's atmosphere trap the sun's heat.
