  • Using your body to control a drone is more effective than a joystick

    If you've ever been chastised for throwing your entire body around during gaming (because physically leaning into track corners definitely helps somehow), here's a bit of science-backed vindication. Researchers in Switzerland have discovered that using your torso to control a drone is far more effective than using a joystick. The team from EPFL monitored the body movements and muscular activity of 17 people, each with 19 markers placed all over their upper bodies. The participants then followed the actions of a virtual drone through simulated landscapes, via virtual reality goggles. By observing motion patterns, the scientists found that only four...

    On his first foreign trip since taking office nearly three months ago, NASA Administrator Jim Bridenstine traveled to Israel last week to meet with the country's prime minister and other officials. Bridenstine's two-day visit to Israel, not announced by the agency until after he arrived in the country, highlighted NASA's good relationship, but only modest cooperation, with Israel's space agency and industry. He separately met with his direct counterpart, Israel Space Agency Director Avi Blasberger, and signed a "joint agreement" on cooperation. That one-page agreement "reaffirmed their strong mutual interest in strengthening cooperation" but did not specify any new initiatives for the...

    One of the experiments astronauts are tending to on the International Space Station could electrify space exploration. The experiment centers on a batch of microbes called Shewanella oneidensis MR-1, which arrived at the station in early July. Here on Earth, Shewanella has an unusual skill: It can produce electricity. The experiment is the first step to determining whether the microbes can do so in space as well — and whether humans can harness that ability to make space exploration easier. The bacterium belongs to a group called exoelectrogens, which can create electricity all by themselves, as NASA explains in a...

    With dynamic growth and access to capital seen as primary factors for jumping three places, the US has regained its status as being on the cutting edge of competitiveness in a ranking by the IMD think tank. A competitive ranking of 63 advanced economies published on Wednesday showed the United States improving three positions to return to the top spot, overtaking Hong Kong, Singapore and the Netherlands, and leaving Switzerland behind.As the top five most competitive countries in the world remained the same — changing only in their order — the American economy's comeback was mainly driven by economic performance,...

    The National Guard in Hawaii is warning of new, immediate dangers to people living near the Kilauea volcano some two-and-a-half months after the eruption started. At the same time lava flow is changing the outline of the island itself and creating hundreds of acres of new land where the ocean used to be. The island has grown by nearly 700 acres, the equivalent of more than 500 football fields, reports CBS News' Carter Evans.

    The War Zone ^ | JULY 16, 2018 | JOSEPH TREVITHICK
    The U.K. Ministry of Defense has unveiled new plans for a new stealth fighter jet called Tempest at the biennial Farnborough Airshow. The announcement coincides with the release of a new Combat Air Strategy, which focuses heavily on sustaining and expanding the United Kingdom’s domestic defense industrial base and international cooperation in that sector, but there are already questions about the project’s viability given the country’s increasingly uncertain political and economic future. Underscoring the emphasis on engagement with the private sector, U.K. Defense Secretary Gavin Williamson offered details about Tempest and the country’s new aerial warfare strategy in front...
  • Shroud of Turin Bloodstains Likely Fake, Not of Jesus Christ: Forensic Experts

    Christian Post ^ | 07/17/2018 | Stoyan Zaimov
    Bloodstains found on the shroud of Turin burial cloth, believed by many to have once wrapped the body of Jesus Christ, are likely fake, according to new research reported in the Journal of Forensic Sciences. In June 2017, researchers at the Institute of Crystallography found traces of blood on the 14-foot-long relic, with initial analysis of the particles discovering "a scenario of great suffering, whose victim was wrapped up in the funeral cloth." The nanoparticles uncovered were found to not be typical of the blood of a healthy person. The Journal of Forensic Sciences report on July 10 revealed that...

    Our universe's rate of expansion keeps getting stranger. New data continues to show a discrepancy in how fast the universe expands in nearby realms and more distant locations.  The study's researchers said this "tension" could mean we need to revise our understanding of the physics structuring the universe, which could include exotic elements such as dark matter and dark energy. New measurements from the Hubble Space Telescope and the Gaia space telescope together showed that the rate of expansion nearby is 45.6 miles per second per megaparsec. This means that for every 3.3 million light-years a galaxy is farther away from...

    Genetically modified babies given go ahead by UK ethics body The creation of babies whose DNA has been altered to give them what parents perceive to be the best chances in life has received a cautious green light in a landmark report from a leading UK ethics body.The Nuffield Council on Bioethics said that changing the DNA of a human embryo could be “morally permissible” if it was in the future child’s interests and did not add to the kinds of inequalities that already divide society. The report does not call for a change in UK law to permit genetically...

  • Did the Human Hand Evolve as a Lean Mean Bone-Smashing Machine?

    Scientists have long linked the evolution of the human hand—unique for its lengthy opposable thumbs and dexterous fingers—to the rise of stone tools some 2.6 million years ago. These instruments, from primitive chunks of rock used as makeshift hammers to sharp stone flakes created by striking one stone against another and even small handaxes, are typically attributed to Homo habilis, an ancient human species nicknamed “handy man” in honor of its theorized role as the first toolmaker. Early hominins practiced an array of tool-related activities, including hunting, foraging and cooking. But according to a new study from researchers at Chatham...

    The ongoing eruption of Hawaii's Kilauea Volcano and continued lava flows into the sea has created a tiny new landmass off the Big Island, officials revealed Friday. The U.S. Geological Survey said the tiny island formed off the northernmost part of the ocean entry from Fissure 8, and was oozing lava similar to that of the larger lava flow along the coast. In photos posted by the agency, the "island" is just a few meters off shore, and about 20 to 30 feet in diameter. "It's most likely part of the fissure 8 flow that's entering the ocean—and possibly a...

    The Shroud of Turin, which has been revered by some Christians as the burial cloth of Jesus, could be a fake, according to a new forensic investigation. The investigation into the bloodstain pattern on the cloth was reported Tuesday in the Journal of Forensic Sciences and is apparently the first such analysis of the controversial shroud. Held in the Cathedral of St. John the Baptist in Turin, Italy, the shroud shows the image of a crucified man and has been analyzed and scrutinized for many, many years. The Vatican regards it as an icon, rather than a religious relic—and the...

    In the lowest layer of the Area 15 archaeological grounds at the Gault Site in Central Texas, researchers have unearthed a projectile point technology never previously seen in North America, which they date to be at least 16,000 years old, or a time before Clovis. While clear evidence for the timing of the peopling of the Americas remains elusive, these findings suggest humans occupied North America prior to Clovis - considered one of the oldest, if not the oldest, Paleo-Indian culture of North America, and dated to around 11,000 years ago. In 2002, Area 15 of the Gault Site in...

The cause of the cooling event, which is named after a flower (Dryas octopetala) that flourished in the cold conditions in Europe throughout the time, has remained a mystery and a source of debate for decades. Many researchers believed the source was a huge influx of freshwater from melting ice sheets and glaciers that gushed into the North Atlantic... However,...

    BBC ^ | February 17, 2011 | Andrew Thompson
    Could an ancient children's burial ground contain clues about how one of the world's greatest empires came to an end? Andrew Thompson explores the theory that malaria was the silent killer responsible for the fall of Rome. Today in the west, most people have forgotten how deadly malaria used to be, although there were serious malarial epidemics in many parts of Italy as recently as the 1950s. But each year, mainly in Africa, it still kills over two million people, most of them children. While there are several mentions of a disease sounding very similar to malaria in historical documents...
