    Spacecraft and satellites could in future be launched into space without the need for fuel, thanks to a revolutionary new theory. Dr Mike McCulloch, from the University of Plymouth, first put forward the idea of quantised inertia (QI) – through which he believes light can be converted into thrust – in 2007. He has now received $1.3million from the United States Defense Advanced Research Projects Agency (DARPA) for a four-year study which aims to make the concept a reality. The QI theory predicts that objects can be pushed by differences in the intensity of so-called Unruh radiation in space, similar...

    Two stunningly preserved ice age mammals were unearthed by gold miners in northwest Canada and unveiled in a ceremony on Thursday. A wolf pup and a caribou calf were found by the miners in the Yukon territory in 2016 in the area's melting permaforst. It's exceedlingly rare for fur, skin and muscle tissues to be preserved in the fossil record, but all three are present on these specimens, which have radiocarbon-dated to more than 50,000 years old, reports the Guardian. The wolf pup is reportedly preserved in its entirety, including exceptional details of the head, tail, paws, skin and hair,...

    The NASA/ESA Hubble Space Telescope has taken a detailed image of a spectacular part of the Coma cluster, a structure of over a thousand galaxies bound together by gravity. The Coma Cluster, also known as Abell 1656, lies in the northern constellation of Coma Berenices, about 300 million light-years away from Earth.Many of the galaxies in the cluster are ellipticals, as is NGC 4860, the brighter of the two galaxies dominating this Hubble image.However, the outskirts of the cluster also host younger spiral galaxies that proudly display their swirling arms.Again, this image shows a wonderful example of such a galaxy...

    How Fast Is Earth Moving? As an Earthling, it's easy to believe that we're standing still. After all, we don't feel any movement in our surroundings. But when you look at the sky, you can see evidence that we are moving. Some of the earliest astronomers proposed that we live in a geocentric universe, which means that Earth is at the center of everything. They said the sun rotated around us, which caused sunrises and sunsets — same for the movements of the moon and the planets. But there were certain things that didn't work with this vision. Sometimes, a...

    The Dangers of Scientism By Philip Cottraux “Science, like other outmoded systems, is destroying itself. As it gains in power, it proves itself incapable of handling the power. Because things are going very fast now…it will be in everyone’s hands. It will be in kits for backyard gardeners. Experiments for schoolchildren. Cheap labs for terrorists and dictators. And that will force everyone to ask the question - ‘What should I do with my power?’ Which is the very question science says it cannot answer.” -Michael Crichton, Jurassic Park****** Atheists often accuse religious people of being anti-science. They cite past examples...
  • Jupiter's Icy Moon Europa Has a Really Weird Cold Spot

    Just because Jupiter's moon Europa is coated in ice doesn't mean all that ice is the same temperature. And now, scientists have mapped the hot and cold spots on the moon's surface using data gathered from Earth, with accuracy down to 125 miles (200 kilometers). While most of the temperature variations they measured can be explained by sunlight's influence on the ice, there's one unusually cold spot that is stumping the scientists behind the new research. That spot, which falls on the moon's northern hemisphere, stood out in images taken at different times of the day, which surprised the scientists....

    A remarkable ring of bright X-ray sources — black holes or neutron stars — has been discovered in a galaxy approximately 300 million light years from Earth. This ring was forged when one galaxy smashed through the middle of another, creating ripples in the gas. “Where did the ring of black holes or neutron stars in this galaxy — the so-called ring galaxy AM 0644-741 — come from? We think that it was created when one galaxy was pulled into another galaxy by the force of gravity,” said Dr. Anna Wolter of the Osservatorio Astronomico di Brera and co-authors.“The first...

    The U.S. Geological Survey (USGS) is starting to earnestly evaluate space resources for future mining.  Since its establishment in the 1870s, the USGS has focused pretty much solely on Earth. But now it's also investigating what benefits may or may not exist in tapping extraterrestrial water, minerals and metals. The agency seeks to portray accurately how humanity could exploit off-Earth assets — a no-nonsense approach that contrasts with the pie-in-the-sky estimates of trillions of dollars of profit proffered by some less scientifically minded space-mining advocates.Proven expertise This past June, several USGS experts took part in a Space Resources Roundtable held at...

    The seven planets orbiting the ultracool dwarf star TRAPPIST-1 are mostly rocky, with some potentially holding more liquid water than Earth. New research reveals the density of the worlds within this crowded system to a greater precision than ever before. The findings reveal that some of the planets could have up to 5 percent of their mass in liquid water form, about 250 times as much water as found in Earth's oceans. "All the TRAPPIST-1 planets are very Earth-like — they have a solid core, surrounded by an atmosphere," In addition to narrowing down the composition of the exoplanets, the...

    Late last week, the astronauts aboard the International Space Station woke up to some distressing news: There was a leak somewhere on the station, and air was escaping into space. After an extensive search, the leak was finally found and plugged with tape and gauze, and the air pressure inside the station has been stabilized. But now that the crisis has passed, there’s a new concern for the astronauts and the space agencies that manage the station. How exactly did that hole get there in the first place? At first, the theory was that a stray micrometeorite collided with the...

    After a catastrophic fire blazed through the National Museum of Brazil on Sunday (Sept. 2), destroying many of the institution's 20 million artifacts, the museum's meteorites were some of the few relics left standing. Among the space rocks that survived the blaze is the Bendegó meteorite, which is the largest meteorite ever found on Brazilian soil. The iron-nickel meteorite is one of about a dozen meteorites housed at the museum. … Officials have not yet been able to tally the damages, as investigators have been instructed to hold off on their work until engineers declare the building safe to enter,...

    PC Science: A newly released study is angering the transgender community for concluding that most young people who ‘come out’ as trans have at least one mental disorder. In the study, which was published at PLoS ONE and focused primarily on female teens, assistant professor of behavioral and social sciences at Brown University Lisa Littman found that 87 percent of young people were reported by their parents to have come out as trans after an increased amount of time spent on social media and the Internet and after “cluster outbreaks” of gender dysphoria among groups of friends.

    “The health risks associated with alcohol are massive,” said study senior author Dr. Emmanuela Gakidou, a researcher in the Institute for Health Metrics and Evaluation at the University of Washington. “Our findings are consistent with other recent research, which found clear and convincing correlations between drinking and premature death, cancer, and cardiovascular problems. Zero alcohol consumption minimizes the overall risk of health loss.” “The study does not distinguish between beer, wine, and liquor due to a lack of evidence when estimating the disease burden,” she added. “However, we used data on all alcohol-related deaths generally and related health outcomes to...

    MU69 is a relatively small Kuiper Belt object. It is estimated to have a diameter of 30 miles (48 km) — that’s more than 10 times larger and 1,000 times more massive than typical comets, but only about 0.5 to 1% of the size of the dwarf planet Pluto. This object was discovered in June 2014 by astronomers using the NASA/ESA Hubble Space Telescope.Also known as PT1 and 1110113Y, and nicknamed Ultima Thule, MU69 orbits the Sun once every 293 years at a distance of more than 4 billion miles (6.5 billion km) from Earth.The MU69 flyby will be the...

    n July of this year (2015), NASA’s New Horizons mission will fly past Pluto and its moons. It will map the surface of the Plutonian system in unprecedented detail, revealing craters and other surface features for the first time. In preparation for the deluge of newly discovered craters, mountains, crevasses and other surface features, Mamajek et al. discuss a naming system for Pluto and its moons. Pluto is one of the last large planetesimals in the Solar system to have its surface imaged in detail. Pluto’s surface features will reveal the history of its life in the alien conditions at...

    The Environmental Protection Agency’s (EPA) internal watchdog is auditing how the agency deals with issues of scientific integrity. In a notice released Friday, the Office of the Inspector General (OIG) said it would launch research into how the EPA implements and adheres to its scientific integrity policy. The audit was launched voluntarily by the office, so it is not connected to a specific request from a lawmaker or complaint. But critics of the Trump administration have nonetheless criticized the agency for what they see as attempts to undermine science at the EPA, including downplaying the harms from climate change and...

    Close encounters with medium-size black holes can reanimate dead stars, if only momentarily, a new study suggests. A team of astronomers performed computer simulations to determine what happens when a burned-out stellar corpse known as a white dwarf passes close to an intermediate-mass black hole — one that harbors between 1,000 and 10,000 times the mass of Earth's sun. The researchers determined that the black hole's powerful gravity can stretch and distort the white dwarf's previously inert innards so dramatically that nuclear-fusion processes can reignite for a few seconds, converting helium, carbon and oxygen into heavier elements such as iron....
