“You have indicated that Mars had — was totally different thousands of years ago,” Rep. Dana Rohrabacher, R-Calif., asked during a hearing of the space subcommittee of the House Committee on Science, Space and Technology. The congressman’s question followed earlier testimony by NASA scientist Kenneth Farley about plans for the Mars 2020 mission, which involves looking for evidence of life on the red planet from the first billion years of the solar system. “Prior to about 3.6 billion years ago, Mars had rivers, lakes and possibly a vast northern ocean,” Farley said earlier in the hearing.
In November 2016, Jude Sparks, now 10, was on an outing with his family near their New Mexico home when he tripped over what he thought was a cow skull. Now, researchers at New Mexico State University are preserving the discovery, which was identified as a Stegomastodon -- a mastodon-like or elephant-like animal. "I imagined through my own mind of being 9 years old and finding something like that and how incredible it would be," dad Kyle Sparks.
A surging wildfire raced through California mountains and foothills west of Yosemite National Park on Wednesday, forcing thousands to flee tiny, Gold Rush-era towns, destroying 29 structures and wafting a smoky haze over the park's landmark Half Dome rock face. The 4-day-old blaze nearly doubled in size overnight to 75 square miles (194 square kilometers), the California Department of Forestry and Fire Protection said. At its closest, the blaze was still about 35 miles from the boundary of Yosemite, where campgrounds are open, park spokesman Scott Gediman said.
The search data that was compiled in the fruitless search for missing Malaysia Airlines Flight MH370 has uncovered some unexpectedly useful information. While surveys of the 46,000 sq miles of the remote waters of Western Australia failed to find the plane, they did provide fresh insight into the region’s past. Information about valuable fish that congregate in the area will also prove useful to the world’s fishermen, according to Charitha Pattiaratchi, professor of coastal oceanography at the University of Western Australia.
California's vast San Joaquin Valley, the country's most productive farming region, is engulfed by some of the nation's dirtiest skies, forcing the state's largest air district to spend more than $40 billion in the past quarter-century to enforce hundreds of stringent pollution rules. The investment has steadily driven down the number of days with unhealthy air — but on hot, windless days, a brown haze still hangs overhead, sending wheezing people with tight chests to emergency rooms and hundreds each year to an early grave. In California, where Democratic Gov. Jerry Brown is an outspoken leader in the global fight against climate change, the San Joaquin Valley Air Pollution Control District now is waging a very public campaign against enforcement of the landmark U.S. Clean Air Act.
The first humans arrived in Australia up to 15,000 years earlier than previously thought, scientists have announced. During excavations of the Madjedbebe rock shelter in northern Australia, researchers have found thousands of artefacts, including stone tools, grinding stones and hatchets, showing humans must have been at the site at least 65,000 years ago. The findings, published in Nature, have major implications for our understanding of early human migration beyond Asia, why Australia’s megafauna went extinct, and, potentially, if these early humans interacted with Homo floresiensis, the mystery “hobbit-like” species found only on the Indonesian island of Flores.
Speaking at the International Space Station Research and Development Conference on Wednesday, Tesla and SpaceX Founder Elon Musk said we need to build a base on the moon to help support missions to Mars and to spur public support for space exploration.
Career site Glassdoor recently unveiled its list of the 50 highest-paying college majors. Not surprisingly, college majors focused on STEM (science, technology, engineering, and math) education came out on top. Through an analysis of resumes and salary reports, Glassdoor came up with a listing of college majors that yield the most earnings during the first five years out of college.
Dogs most probably evolved from wolves at a single location about 20,000 to 40,000 years ago, a study suggests. Previously, it had been thought that dogs were tamed from two populations of wolves living thousands of miles apart. Researchers studied DNA from three dogs found at archaeological sites in Germany and Ireland that were between 4,700 and 7,000 years old. The ancient canines share ancestry with modern European dogs. By looking at the rates of change to the DNA from the oldest specimen, scientists were able to place the timing of the domestication of dogs to between 20,000 and 40,000 years ago. Krishna Veeramah of Stony Brook University in New York is a researcher on the study. He said

History buffs may have a reason to rejoice after a team of archeologists found evidence of a tomb, which they believe to be that of King Tutankhamun’s wife Ankhesenamun. "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.
A bag containing traces of moon dust is heading to auction — surrounded by some fallout from a galactic court battle. The collection bag, used by astronaut Neil Armstrong during the first manned mission to the moon in 1969, will be featured Thursday at a Sotheby's auction in New York City of items related to space voyages. The artifact from the Apollo 11 mission was misidentified and sold at an online government auction.
The world’s most destructive mud volcano was born near the town of Sidoarjo, on the island of Java, Indonesia, just over 11 years ago – and to this day it has not stopped erupting. The mud volcano known as Lusi started on May 29, 2006, and at its peak disgorged a staggering 180,000 cubic metres of mud every day, burying villages in mud up to 40 metres thick. The worst event of its kind in recorded history, the eruption took 13 lives and destroyed the homes of 60,000 people. The debate is whether the eruption of Lusi was due to an earthquake several days previously, or down to a catastrophic failure of the Banjar Panji 1 gas exploration well that was being drilled nearby at the time.
Lightning struck twice for the crew of the trawler ship Cú na Mara. On Tuesday, they caught their second rare giant squid in the waters off the Dingle coast in Ireland, two months after their first. The Cú na Mara had been trawling the area where they had found their first giant squid when they landed their surprise second.
Fifty years ago, if you'd asked the dinosaur experts, they would have told you that Tyrannosaurus rex was a speed freak — a giant predator that could outrun racehorses. The paleontologists would have pointed to its 3-meter hind limbs, leggy for even a big dinosaur, and described the creature as sprinting after prey at speeds of 40 mph. But a better understanding of physics kneecapped the swift T. rex concept. Scientists, rather than looking at the bones alone, began to gauge dinosaur locomotion via models of skeletons and muscles. The picture that came into focus was a slower beast: T. rex, although no less of a predator, was certainly less fleet of foot. A new report, published Monday in the
In the study, people who were shown a number of real and fake images spotted the fake photos about 60 percent of the time, which is only a little bit above the 50 percent accuracy rate that would be expected by chance. "Our study found that although people performed better than chance at detecting and locating image manipulations, they are far from perfect," Sophie Nightingale, a doctoral candidate in psychology at the University of Warwick in England and lead author of the study, said in a statement. "This has serious implications because of the high level of images, and possibly fake images, that people are exposed to on a daily basis through social networking sites, the internet and the media," Nightingale said.
A recent survey of children aged eight to 12 found that indoor play is now the norm, a third have never splashed in a puddle and the distance children are allowed to play from home has shrunk by 90% since 1970. Parenting hasn’t only changed in terms of what is considered safe for children. Parents now worry more about the impact of their parenting on their children, feeling pressured to provide a stream of stimulating activities in a way that would have once seemed absurd.
A new unique study from the University of Warwick in the United Kingdom looked at a group of participants and asked them to detect digitally manipulated fake images. They found that one third of the fake and altered images went undetected by most participants. The study entitled “Can people identify original and manipulated photos of real-world scenes?” was published in the journal Cognitive Research: Principles and Implications. Samples of manipulated photos. a Original photo; b airbrushing—removal of sweat on the nose, cheeks, and chin, and removal of wrinkles around the eyes; c addition or subtraction—two links between the columns of the tower of the suspension bridge removed; d geometrical
On August 21, the continental United States will see its first total solar eclipse in 38 years. The shadow of the moon will cross the country, touching land in Oregon and leaving from South Carolina, providing an opportunity for what may be an unprecedented number of people to witness this extraordinary natural phenomenon. Total solar eclipses are a big deal not because of how infrequent they are — there’s a total solar eclipse every 18 months on average — but because of how little of the Earth’s surface falls in the path of any given eclipse shadow. The next total solar eclipse to visit the US will be in 2024. If an eclipse happens to come to your town, you’re lucky. Any given location will
Updated | A Republican congressman from California on Tuesday asked members of a NASA panel if there had been ancient civilizations on Mars. Addressing a NASA scientist testifying before the House Committee on Science, Space and Technology, U.S. Representative Dana Rohrabacher said, “You have indicated that Mars was totally different thousands of years ago,” according to a video posted to YouTube. In his answer, Ken Farley, a project scientist on NASA’s Mars 2020 Rover mission team, corrected Rohrabacher by saying the evidence shows that Mars was different billions—not thousands—of years ago.
Air Force Secretary Heather Wilson chats with Stratolaunch CEO Jean Floyd (left) at the company’s hangar in Mojave, Calif. The twin-tailed airplane is behind them. Stratolaunch, the six-year-old space venture backed by Microsoft co-founder Paul Allen, says it’ll use the world’s biggest airplane to launch small satellites into orbit – but what kind of satellites? The company’s executives have always said the Pentagon could be a payload customer, but when Air Force Secretary Heather Wilson visited Stratolaunch’s super-hangar at the Mojave Air and Space Port in California on Monday, it threw a spotlight on how important military contracts could be.
Vietnam agreed Wednesday to rescue more than 1,000 bears from illegal farms across the country, in a move to end the traditional medicine trade in the creatures' bile. Vietnam's Administration of Forestry (VNFOREST) and non-profit group Animals Asia signed an agreement Wednesday to rescue all remaining bears from farms, committing to end bile trade and close all facilities within five years. "This is a truly historic day," Animals Asia CEO Jill Robinson at the signing in Hanoi, adding that the decision "will lead to the definitive end to bear bile farming here in Vietnam".
Having Neil deGrasse Tyson on the set of Salvation was a special moment for the executive producers — and apparently, it was special for Tyson too. When the renowned astrophysicist filmed his cameo in the pilot, EP Craig Shapiro asked why he agreed to appear on the show, since Tyson no doubt receives millions of offers. “He said he liked the project because it took science and the scientists seriously and their work was treated as serious work and not just a throwaway plot point, and that the scientists were very human and were not robots in a lab somewhere,” Shapiro tells EW.
Dogs and humans may have had a similar relationship as far back as 14,000 years ago in hunter-gatherer communities. About 7,000 years ago, these farming communities had just arrived in Europe, replacing hunter-gatherer societies and creating denser groups of people. This would have probably altered the dogs' behavior as well, as they adapted to be around more people. Rather than being kept as house pets, these dogs probably roamed close to or within villages. And food-wise, they may have needed to fend for themselves and scavenge, according to Adam Boyko, assistant professor at Cornell University's department of biomedical sciences, who was not associated with the study. Unlike modern dogs, they
In a story July 18 about plans to honor the late astronaut John Glenn, The Associated Press reported erroneously when Glenn became the oldest person to travel in space. Some plans to honor John Glenn didn't fly, but that hasn't stopped devotees of the late astronaut from pushing forward with other ideas. COLUMBUS, Ohio (AP) — Some plans to honor John Glenn didn't fly, but that hasn't stopped the late astronaut's devotees from pushing forward with other ideas.
