A giant flying reptile the size of a plane may have been the largest and most feared predator in ancient Transylvania. After examining the enormous neck vertebrae of a creature called Hatzegopteryx– a pterosaur with a 32–foot wingspan and giant beak– researchers now believe it was a fierce carnivore that preyed on dinosaurs and other animals in Romania during the Cretaceous period. “We've suspected that some giant pterosaurs were terrestrial foragers for a while now, but the idea that one could be a stocky, powerful apex predator is not something anyone would have predicted even a few years ago,” study author Dr. Mark Witton of the University of Portsmouth told Fox News. “Indeed, it wasn't that
Hundreds of scientists, environmental advocates and their supporters held a rally in Boston on Sunday to protest what they see as increasing threats to science and research in the U.S. The scientists, some dressed in white lab coats, called on President Donald Trump's administration to recognize evidence of climate change and take action on various environmental issues.
In 2012, the International Union for Conservation of Nature listed the Madagascar natives as the most endangered mammals on the planet. “The original inspiration for developing LemurFaceID was a desire to develop a noninvasive tool that would help us ID and track lemurs,” Stacey Tecot, University of Arizona assistant professor and senior researcher of the project, told Digital Trends. To minimize invasiveness, Tecot and her colleague, George Washington University’s Rachel Jacobs, decided not to capture or tag their subjects, but soon found that such a hands-off approach made collecting sufficient datasets difficult.
The Pentagon is reportedly rushing to develop a drone laser weapon capable of zapping rockets almost as soon as they are launched. According to Las Vegas Review-Journal, the Missile Defense Agency said it has conducted tests of a "directed-energy airborne laser" fired from a military drone – a weapon that would be carried by remote-control aircraft over suspected enemy ballistic missile launch sites. The current system relies on "metal-to-metal" missile interceptors guided by radar and satellites, the outlet reported. "This could revolutionize missile defense, dramatically reducing the role of kinetic interceptors," agency spokesman Christopher Johnson told the outlet in an email. Johnson said
In a Mexican cave system so beautiful and hot that it is called both fairyland and hell, scientists have discovered life trapped in crystals that could be 50,000 years old. The bizarre and ancient microbes were found dormant in caves in Naica, Mexico, and were able to exist by living on minerals such as iron and manganese, said Penelope Boston, head of NASA’s Astrobiology Institute. “It’s super life,” said Boston, who presented the discovery Friday at the American Association for the Advancement of Science conference in Boston. If confirmed, the find is yet another example of how microbes can survive in extremely punishing conditions on Earth. Though it was presented at a science conference and
John Glenn is continuing to inspire 55 years after becoming the first American to orbit Earth. Since Glenn's death on Dec. 8 at the age of 95, untold numbers of devotees have stopped by an exhibit of his artifacts on the campus of Ohio State University, backers have begun fundraising for an observatory and astronomy park in Glenn's name and work has begun on a 7-foot statue in his likeness. For 4 hours, 55 minutes and 23 seconds on Feb. 20, 1962, the capsule circled the Earth three times, making Glenn the first American to orbit Earth.
Tiny natural ponds pose an overlooked danger for speeding up global warming, according to a study published Monday in the journal Nature Climate Change. In experiments designed to simulate moderate future warming, scientists in Britain found that such ponds -- a metre (three feet) across -- gradually lose the capacity to soak up one kind of greenhouse gas and give off even more of another. After seven years at higher-than-ambient temperatures, "the ability of the ponds to absorb carbon dioxide was reduced by almost half, while methane release nearly doubled," said lead-author Gabriel Yvon-Durocher, a professor at the University of Exeter.
A geological analysis of the Rockall area of the North Atlantic has revealed previously unknown insights that could lead to new oil and gas discoveries in the UK Continental Shelf (UKCS). Previous attempts to find hydrocarbons in Rockall have been largely unsuccessful, with only one gas discovery out of 12 wells drilled. Those behind the study believe that misconceptions regarding the character of the Basin - as well as challenging weather conditions and a lack of supporting infrastructure due to its remoteness - have hampered these exploration efforts. Dr Nick Schofield from the University’s Department of Geology and Petroleum Geology led the analysis, which has been funded by a $311,875 (GBP
That little blue dot likes to mock. Glowing bright on a smartphone’s map, it’s usually a reliable marker of the user’s location. Except when it’s not. Anyone who’s tried to use it to navigate out of a subway station, a mall or a high-rise apartment complex can attest to the frustration of the blue dot that is just pretending to know which way they’re facing or where they are (no, not in that river two blocks away). The consequences of using the wrong exit out of a shopping center are minimal, but when it’s a firefighter trying to make her way out of a burning building, the stakes for tracking her precise location and orientation are high. A system is being developed at NASA’s Jet Propulsion Lab
The dwarf planet Ceres keeps looking better and better as a possible home for alien life. NASA's Dawn spacecraft has spotted organic molecules — the carbon-containing building blocks of life as we know it — on Ceres for the first time, a study published Feb. 16 in the journal Science reports. And these organics appear to be native, likely forming on Ceres rather than arriving via asteroid or comet strikes, study team members said. [Photos: Dwarf Planet Ceres, the Solar System's Largest Asteroid] "Because Ceres is a dwarf planet that may still preserve internal heat from its formation period and may even contain a subsurface ocean, this opens the possibility that primitive life could have developed
Friend dating someone you suspect to be a sociopath? Knowing what you’re dealing with and coming to terms with the psychological disorders of those around us can make things easier for everyone. Of course, terms like psychopath and sociopath make people uneasy.
The device has been developed by researchers from the University of British Columbia (UBC) and could help ease treatments for patients required to take many pills or undergo regular intravenous injections. A major benefit beyond its minimal invasiveness is that, unlike similar devices, which need a power source to disperse medication, the UBC device needs only an external magnetic field. “We had a prior work on magnetic drug delivery device that contains a membrane and a drug reservoir,” Mu Chiao, a UBC professor of mechanical engineering who supervised the project, told Digital Trends.
Getting through college isn't easy, and it can be even harder for low-income and first generation students with few support resources. Researchers at Georgia State University spent four years analyzing students' grades, test scores and other information in order to identify those in potential trouble, and promptly assisted them. The study shows the number of students graduating has jumped by 30 percent and that students are spending less time and money to earn a degree.
It's a vast, strange land; its canyons and mountain ranges almost entirely unexplored, its creatures like something out of myth. From what we know, it's beautiful — stretching more than a thousand miles from Savage Seamount across Three Kings Ridge, past swamp forests and volcanoes to the southern slopes. Pigeons feed on cabbage trees in Zealandia, whales have beaks, and peanut worms crawl above light-less abysses. In the last fraction of its long history, a relatively small band of humans has settled Zealandia's greatest mountain peaks, which they call the islands of New Zealand. This place exists, though most of the 2 million square miles lie beneath the Pacific Ocean. That shouldn't prejudice
A federal appeals court will hear arguments Tuesday over the constitutionality of Ohio's lethal injection process as the state tries to start carrying out executions once again. At issue is whether a contested sedative, midazolam, is powerful enough to put inmates into a deep state of unconsciousness before two subsequent drugs paralyze them and stop their hearts. A related issue is whether Ohio has a realistic chance of finding an alternative drug — a barbiturate called pentobarbital — that once was widely used in executions but has become difficult or, in Ohio's case, impossible to obtain.
Scientists under the guidance of Mosaic (Multidisciplinary drifting Observatory for the Study of Arctic Climate) mission will attempt a round-the-year expedition of the North Pole or the Arctic Pole to study climate patterns, especially the rapid melting of ice on the pole. The expedition will be the first since Norwegian explorer Fridtjof Nansen's attempt in 1893 to reach the North Pole by using the natural drift of the polar ice. The scientists aim to undertake the operation on board a 120m-long German research vessel, the Polarstern, to answer big questions about the Arctic, including why the region is warming faster than any other place on Earth. "The decline of Arctic sea-ice is much faster

In modern times, a strain of salmonella called Paratyphi C. causes a typhus-like outbreak called enteric fever that can kill as many as 15 percent of those it infects, mostly in developing countries. Now, evolutionary geneticists think this strain of salmonella could be what sickened and killed millions of natives in Mexico in the 1500s, essentially bringing about the collapse of the Aztec empire. Reporting on the bioRxiv server, researchers say they sequenced fragments of DNA taken from the teeth of 29 bodies buried in the Oaxacan highlands of Mexico after an outbreak around 1550. In those fragments, they saw evidence of the salmonella strain. "It’s a super-cool study," one ancient-DNA researcher
We all learned in school that there are seven continents on Earth, but we didn't take into account the new fancy Zealandia, which will hopefully save all our sorry asses. Scientists discovered a massive landmass that's 94% submerged under the Pacific Ocean. (You'd think that wouldn't qualify it as "land," but nothing makes sense!) You've likely heard of a tiny portion of the possible continent: New Zealand and New Caledonia, the six percent that isn't submerged in the depths. However, according to BBC, Zealandia is a whopping 1.9 million square miles. \Scientists are currently pushing for Zealandia to be officially recognized as a continent, due to its meeting important criteria that apparently
Hundreds of millions could be wiped out by viruses that have been genetically engineered by terrorists, Bill Gates has warned. Technological and scientific advances are allowing terror groups to turn viruses into bioweapons of mass destruction. That makes bioterrorism a bigger threat to humanity than nuclear war, he added. The Microsoft founder said: “Natural epidemics can be extremely large. “Intentionally caused epidemics, bioterrorism, would be the largest of all. “With nuclear weapons, you’d think you would probably stop after killing 100 million. “Smallpox won’t stop. Because the population is naïve, and there are no real preparations. “That, if it got out and spread, would be a larger number.”
Thousands of schoolchildren in Kenya are getting a rare opportunity to look at the stars. The Traveling Telescope visits some of this East African country's most remote areas, showing students the night sky and the describing the science of astronomy with telescopes and virtual reality goggles. One by one, the children in this Rift Valley town lined up to peer through the telescope.
Stand on the observation deck of the world's tallest building and you'll find yourself gazing out over the UAE city of Dubai, a super-modern, gleaming metropolis built slap in the middle of a desert. The digital telescopes atop the 830-meter-tall Burj Khalifa let you flick between a live view, a night view, and an intriguing "historic view" that shows how the surroundings used to look around 30 years ago when the first of its several hundred skyscrapers started to go up. With that in mind, perhaps the United Arab Emirates' proposal to build a city on Mars within 100 years doesn't sound like such a daft idea. After all, with the construction of Dubai and the other Emirates, the UAE has already achieved something remarkable in one of the harshest, hottest, driest, and dustiest environments on our own planet.
A leading scientist has suggested that placing humans into a state of hibernation could be a powerful new tool for fighting cancer, in particular terminal cancers. Professor Marco Durante, from the Trento Institute in Italy, has suggested that if humans could be successfully placed into a hibernation state then it would stop the cancer in its tracks. In addition it would also make radiotherapy far more effective as inactive tissue responds better to this form of treatment. Speaking to the BBC World Service Professor Durante said: “The main problem was that humans don’t go into hibernation of course, bears go into hibernation, squirrels go into hibernation but humans don’t.” “However recently
The "Tully Monster" was probably not a vertebrate, scientists have said, contradicting the conclusions of two other high-profile studies published last year. They hope to encourage more researchers to take on the challenge of finding out where the mysterious creature belongs on the tree of life. The Tully Monster is an iconic 300 million year-old, soft-bodied fossil from the Mazon Creek fossil beds in the USA. It was first discovered by amateur palaeontologist Francis Tully in 1958, but many other specimens have been found since then. The creature continues to fascinate and puzzle scientists, as they struggle to define what type of animal it was. In 2016, there seemed to be a breakthrough, as
