A University of Maine professor has died while conducting research in Antarctica. The university says 50-year-old Gordon Hamilton died Saturday when the snowmobile he was riding hit a crevasse and he fell 100 feet. He had been in Antarctica doing research for the National Science Foundation. His work focused on the role of ice and glaciers in the climate system. Hamilton began working at the University of Maine's Climate Change Institute in 2000. He served as an assistant research professor, taught undergraduate and graduate courses and worked with a statewide initiative on science, technology, engineering and math programs for high school students. UMaine provost Jeffery Hecker released a statement
On Sunday evening, Elon Musk, the billionaire tech mogul and nerd hero behind Tesla Motors, hosted a special two-hour Q&A session on Reddit. The AMA, which lasted roughly two hours, was intended as a supplement to the presentation he gave on during last month’s International Astronautical Congress. Which, in turn, meant questions were limited to the fledgling commercial rocket program, and Interplanetary Transport System, not Musk's electric car company or recently consolidated renewable energy firm, SolarCity.
New research shows that the part of the brain that is activated during dishonesty responds less and less as we “get used” to cheating — and that could make us lie even more. Brain scans of the participants confirmed that lying can be a slippery slope: people did lie more over time. When we deceive someone, the part of the brain that regulates emotion — called the amygdala — is activated, and we often feel shame or guilt.
Unfortunately, not everyone made it, as at least 14 bodies were recovered and dozens more remain missing, Italian officials said. Italy's Guardia Costiera, or Coast Guard, shared two videos on Sunday from the dozens of rescue operations this weekend in the central Mediterranean. Officials said 2,400 people were rescued on Saturday by the coast guard, ships from nongovernmental organizations and the Irish Navy, according to ANSA, Italy's leading news agency.
The concentration of carbon dioxide (CO2) in the atmosphere has passed an ominous milestone, ushering the planet into "a new era" of climate change, the UN said Monday. For the first time on record, the amount of CO2 in the atmosphere averaged 400 parts per million (ppm) in 2015, the World Meteorological Organization (WMO) said in its latest Greenhouse Gas Bulletin. CO2, the main greenhouse gas driving climate change, has previously passed the 400 ppm threshold on certain months in specific locations but never on a globally averaged basis, WMO said.
If you were trying to catch up on the latest news or check out what was trending on Twitter this morning, you might have received a message that said that your browser couldn't connect to the server. Twitter, Reddit, Spotify and even news sites such as CNN experienced a widespread outage early today due to a so-called DDoS cyberattack that affected many users on the East Coast of the United States, according to several news outlets. The culprit behind the outage is what's known as a distributed denial-of-service attack, or DDoS, which was mounted against a company called Dyn DNS.
The International Space Station received its first shipment from Virginia in more than two years Sunday following a sensational nighttime launch observed 250 miles up and down the East Coast. Orbital ATK's cargo ship pulled up at the space station bearing 5,000 pounds of food, equipment and research. "What a beautiful vehicle," said Japanese astronaut Takuya Onishi, who used the station's big robot arm to grab the vessel. The capture occurred as the spacecraft soared 250 miles above Kyrgyzstan; Onishi likened it to the last 195 meters of a marathon. Last Monday's liftoff from Wallops Island was the first by an Antares rocket since a 2014 launch explosion. Orbital ATK redesigned its Antares rocket
The third-largest earthquake in Oklahoma was likely triggered by underground disposal of wastewater from oil and natural gas production, the U.S. Geological Survey found in a report issued Monday. The magnitude 5.1 quake that struck northwest of Fairview in February was likely induced by distant disposal wells, the agency said. The USGS report indicated that in the area around where the Fairview quake occurred, the volume of fluid injected had increased sevenfold over three years.
By Andrew M. Seaman (Reuters Health) - Children's brains undergo noticeable changes after just one season of football, even if they were never diagnosed with a concussion, according to a new imaging study. While there is no way to know whether the changes may lead to health problems down the road, the researchers found that the degree of change seen in the brain's white matter tracts was tied to the amount of exposure a child had to head impacts during play. "It’s really another study that suggests there are changes in the brain associated with all of these head impacts," said lead author Dr. Christopher Whitlow, of the Wake Forest School of Medicine in Winston-Salem, North Carolina.
The "Bermuda Triangle" is the stuff of legend — in both senses of the word. The area of the Atlantic Ocean between Florida, Puerto Rico, and Bermuda has seen its share, or maybe more than its share, of mysterious disappearances of ships and aircraft, leading to a popular theory that some paranormal force is at work in the triangular body of water. Two meteorologists tell the Science Channel that hexagonal cloud patterns, 20 to 55 miles across, are likely to blame for the Bermuda Triangle phenomenon. "These types of hexagonal shapes over the ocean are in essence, 'air bombs,'" said Dr. Randy Cerveny at Arizona State University. "They're formed by what are called microbursts. They're blasts of
One of the biggest accomplishments that a professor can achieve is reaching tenure, a process that is surely expedited by having your paper recognized by a scientific conference. Unfortunately, how Christoph Bartneck got to that point leaves more questions than answers, reports The Guardian. An associate professor at the Human Interface Technology laboratory at the University of Canterbury in New Zealand, Bartneck received an invitation from the International Conference on Atomic and Nuclear Physics.
Telling little fibs leads down a slippery slope to bigger lies — and our brains adapt to escalating dishonesty, which makes deceit easier, a new study shows. Neuroscientists at the University College London's Affective Brain Lab put 80 people in scenarios where they could repeatedly lie and get paid more based on the magnitude of their lies. The researchers then used brain scans to show that our mind's emotional hot spot — the amygdala — becomes desensitized or used to the growing dishonesty, according to a study published online Monday in the journal Nature Neuroscience.
Famed billionaire and wannabe space cadet Elon Musk took to Reddit to do a surprise AMA yesterday. It was supposed to be a follow-up to SpaceX's recent announcement about how it plans to return Elon Musk to his place of birth, and also create a permanent Mars colony along the way. Given that Musk insisted questions stick on the topic of SpaceX and its recent announcement, much of the conversation was centered around highly technical details.
Pro- and anti-whaling nations clashed at a key meeting Monday where Japan sought to ease a 30-year-old moratorium on commercial hunts while others pushed for an Atlantic whale sanctuary. Host Slovenia urged compromise the sake of the marine mammals -- some species of which were hunted to near-extinction in the 20th century -- but member states of the International Whaling Commission (IWC) soon split into familiar factions. Japan, which conducts a yearly whale hunt in the name of science, which its detractors say is for meat, insisted that stocks of some species have recovered sufficiently to make them fair game.

After two years in operation, the satellite-imaging startup Planet tells Quartz that it is now photographing more than 50 million square kilometers of the earth every single day. Indeed, in September 2016 alone, the company says it imaged 91% of earth’s land mass. Planet’s plan is to make that imagery available to the public, with free basic access and premium accounts for higher quantity and quality data.
An appeals court panel on Monday ruled that a federal agency acted reasonably in proposing to list a certain population of bearded seals threatened by sea ice loss. The decision by a three-judge panel of the 9th U.S. Circuit Court of Appeals in San Francisco reverses a lower court ruling that found the decision by the National Marine Fisheries Service was improper. At issue was whether the fisheries service can protect species as threatened under the Endangered Species Act when it determines that a currently non-endangered species will lose habitat due to climate change in coming decades.
Google has a new doodle on their homepage today, celebrating the, er, 384th birthday of Antoni van Leeuwenhoek, the Dutch textile salesman considered the first microbiologist. Van Leeuwenhoek designed a single-lens microscope which he used to observe what he famously called "little animals" - single cell organisms that we now know as bacteria and other microbes. The famous phrase came from a letter to the Royal Society of London, in which van Leeuwenhoek marveled at what he had seen in a sample of water from a nearby lake. On its Doodle page, Google says, "In his rooms on the Market Square in Delft, Netherlands, van Leeuwenhoek was a DIY-er supreme.
Between 2000 and 2013, there were more than 18,000 reports of snakebites in children in the U.S., the researchers wrote in their study, which was published Oct. 20 in the journal Pediatrics. About half the snakebites that were reported were from venomous snakes, according to the study. Bites from cottonmouths (Agkistrodon piscivorus) accounted for 6 percent of bites, while 3 percent came from coral snakes and 1 percent came from exotic venomous snakes, the researchers found.
The Black Sea Maritime Archaeology Project had intended to find out how quickly water levels rose in the Black Sea after the last Ice Age, but the team ended up discovering a whole lot more than they had bargained for, Quartz reports. While examining the seabeds, the scientists found dozens and dozens of previously undiscovered shipwrecks — 41 in all. "The wrecks are a complete bonus, but a fascinating discovery, found during the course of our extensive geophysical surveys," the project's principal investigator, Jon Adams, said in a statement. Many of the shipwrecks were in spectacular condition due to the low oxygen levels that exist nearly 500 feet below the surface. "Certainly no one has achieved
About 2,500 years ago, mourners buried a man in an elaborate grave, and covered his chest with a shroud made of 13 cannabis plants, according to a new study. The grave is one of a select few ancient Central Eurasian burials that archaeologists have found to contain cannabis. This particular grave, located in northwestern China, sheds new light on how prehistoric people in the region used the plant in rituals, the researchers said. Archaeologists came to the site and quickly discovered a bounty of artifacts buried in the graves — bows, arrows and the remains of domesticated animals, including goats, sheep and a horse skull — indicating that these ancient people engaged in both hunting and animal husbandry, the researchers said.
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.
Sixty-eight may not seem that old, but for Snooty the manatee, it's a world record. Snooty is now the world's oldest manatee living in captivity, the Guinness World Records recently announced. The sea cow was brought to South Florida Museum as an 11-month-old calf in 1949.
NASA has used virtual reality for decades. Jeff Norris, mission operations innovation lead at the NASA Jet Propulsion Laboratory, told Digital Trends that his lab has active partnerships with almost every company that makes a device you can put on your head, including Valve, HTC, Microsoft, Sony, Oculus, Samsung, and others. “The difference in our work due to the consumer electronics industry’s investment in VR and AR has been profound for us,” Norris said.
It’s as inevitable as grey hair and wrinkles—when we get old, our memories decline, even if Alzheimer’s or dementia doesn’t accelerate that process. But there are a select few whose memories seem to remain as hale as those decades younger. Scientists call them superagers. And now, there is some clarity as to how these superagers hold on to their robust memory. In superagers, the brain networks used for memory, learning, and resilience are nearly untouched by age. While other areas of their brains atrophied, the memory networks of superagers aged 60 to 80 were as healthy as those of the average 18-to-32-year-old’s brain, researchers at Massachusetts General Hospital reported recently in the Journal
