  • What does a 45,000-year-old femur mean for the Neanderthal in you?

    A genetic analysis of a 45,000-year-old thigh bone narrows down the time when modern humans and Neanderthals first interbred.A 45,000-year-old leg bone is raising questions about just how close modern-day humans are to our thick-browed Stone Age ancestors. DNA from the femur of a Siberian man is helping to pinpoint when modern humans and Neanderthals first interbred, researchers say. But what does this mean for the human connection to a species that disappeared nearly 30,000 years ago? The thigh bone, spotted six years ago on the banks of the Irtysh River in Siberia by a Russian artist who carves jewelry...

    Mario Anzuoni/Reuters Elon Musk, CEO of SpaceX and Tesla. While it's certainly impressive that Elon Musk has bachelor's degrees in physics and economics from the University of Pennsylvania, it's an absurd understatement to say that prepared him to run SpaceX, his spacecraft company. Jim Cantrell, who was an aerospace consultant at the time, became SpaceX's first VP of business development and Musk's industry mentor when the company launched in 2002. He says that Musk literally taught himself rocket science by reading textbooks and talking to industry heavyweights.

    Video Link Here Trinity and Beyond: The Atomic Bomb Movie is a 1995 American documentary film directed by Peter Kuran and narrated by William Shatner. Using restored archive footage, the film traces the development of nuclear weapons and their testing, from America's Trinity test of 1945 (hence the title) to the first Chinese atomic bomb test in 1964. Kuran's commentary on the DVD version claims that the DVD replaces some of the original footage with better-quality versions. There are some short special effects sequences too.

    John Coleman, who co-founded the Weather Channel, shocked academics by insisting the theory of man-made climate change was no longer scientifically credible. Instead, what 'little evidence' there is for rising global temperatures points to a 'natural phenomenon' within a developing eco-system. In an open letter attacking the Intergovernmental Panel on Climate Change, he wrote: "The ocean is not rising significantly. "The polar ice is increasing, not melting away. Polar Bears are increasing in number. "Heat waves have actually diminished, not increased. There is not an uptick in the number or strength of storms (in fact storms are diminishing). "I have...

    Never let it be said that Mother Nature doesn’t appreciate irony. A new study led by researchers at Occidental College and the University of California at Santa Barbara has found that the oil platforms dotting the California coast are fantastic for sea life. In a 15-year study, researchers found that the ecosystems that build up around artificial rigs host 1,000 percent more fish and other sea life than natural habitats such as reefs and estuaries. The California rigs outstripped even famously rich ecosystems such as the coral reefs of French Polynesia. Now, as a big fan of artificial reefs, I...

Bentley is alone because its owner, a nurse at Dallas Presbyterian Hospital, is being treated for Ebola. If fears of Ebola's spread weren't bad enough, the dog's life in isolation surely causes pet owners to shudder. The good news is that international research has found that your beloved pooch, cat or cow has little chance of spreading Ebola, said Dr. Rod Hall, Oklahoma's state veterinarian. “There are a lot more things I lay awake worrying about at night than...

    They may have been plant-eaters, but stegosaurs were no easy prey: Researchers have found the fossil remains of what might be a deadly wound inflicted by the creature's spiked tail. Stegosaur tails have been a matter of some debate. While paleontologists used to say they were only for decoration, recent studies have suggested that the spiked, dexterous tails were actually used in combat. In 2005, researchers reported that a non-fatal wound found in the fossil of an allosaur -- a fearsome predator of stegosaurus's age -- was most likely inflicted by a stegosaur tail. But it turns out that those...

    What we can learn from the boot leather, organization and quick response times that stopped Ebola from spreading in this African nation …………… …….the rapid action after Nigeria's index patient was diagnosed helped keep the outbreak from spreading more widely. "In contrast the initial outbreak in Guinea remained undetected for several weeks," they wrote. "This detection delay facilitated the transnational spread of the virus to Sierra Leone and Liberia while difficulties and at times inability to track and contain infectious individuals compounded the situation and resulted in an as yet uncontrolled epidemic in these countries."

    A magnetic field shift is old news. Around 800,000 years ago, magnetic north hovered over Antarctica and reindeer lived in magnetic south. The poles have flipped several times throughout Earth's history. Scientists have estimated that a flip cycle starts with the magnetic field weakening over the span of a few thousand years, then the poles flip and the field springs back up to full strength again. However, a new study shows that the last time the Earth's poles flipped, it only took 100 years for the reversal to happen. The Earth's magnetic field is in a weakening stage right now....

Instead, new research in both planetary/space science and multiple earth-science specialties reveals that concomitant volcanic activity and the associated climate and environmental changes were significant contributing factors in four of the five major mass extinctions in Earth history.

The plates are significantly larger and more robust than those comprising the corpus of known copper plates or tablets, and most significantly differ in being inscribed with mirrored characters. One of the plates bears 34 characters, which is the longest known single Indus script inscription. Examination of the plates with x-ray fluorescence (XRF) spectrophotometry indicates metal compositions, including arsenical copper, consistent with Indus Valley technology.

Ninety-four percent of these travelers will receive enhanced screening. Curious about the 94% figure, I did some research and learned that enhanced screening will be implemented at the five international airports that “manage more than 94 percent of travelers from Liberia, Sierra Leone and Guinea….”...

    Explanation: This looks like a near miss but the greenish coma and tail of Comet Siding Spring (C/2013 A1) are really 2,000 light-years or so away from the stars of open cluster Messier 6. They do appear close together though, along the same line-of-sight in this gorgeous October 9th skyscape toward the constellation Scorpius. Still, on Sunday, October 19th this comet really will be involved in a near miss, passing within only 139,500 kilometers of planet Mars. That's about 10 times closer than any known comet flyby of planet Earth, and nearly one third the Earth-Moon distance. While an impact...

The discovery could virtually reinvent the world in the same way that the telephone, the jet engine, and the silicon chip have done over the years. Or not. They don't expect to have a working commercial reactor for a decade and there's no guarantee of success. Still, the Skunk...

    John West Explicates C.S. Lewis on Science, Scientism, and Skepticism David Klinghoffer October 15, 2014 3:34 PM | Permalink The Christian Post has a very thoughtful and thorough account of a presentation that Discovery Institute's John West gave at the National Conference on Christian Apologetics, analyzing C.S. Lewis's views on science and scientism. It's very much worth reading. One of the important and counterintuitive insights that Lewis offered was his observation that far from encouraging skepticism, the mention of "science" can call forth a perilous gullibility, not least from educated, intelligent people who should know better.Writes reporter Napp Nazworth: Healthy...
  • Lockheed Martin makes fusion breakthrough

    Hidden away in the secret depths of the Skunk Works, a Lockheed Martin research team has been working quietly on a nuclear energy concept they believe has the potential to meet, if not eventually decrease, the world’s insatiable demand for power. Dubbed the compact fusion reactor (CFR), the device is conceptually safer, cleaner and more powerful than much larger, current nuclear systems that rely on fission, the process of splitting atoms to release energy. Crucially, by being “compact,” Lockheed believes its scalable concept will also be small and practical enough for applications ranging from interplanetary spacecraft and commercial ships to...

    Explanation: What is that changing object in a cold hydrocarbon sea of Titan? Radar images from the robotic Cassini spacecraft orbiting Saturn have been recording the surface of the cloud-engulfed moon Titan for years. When imaging the flat -- and hence radar dark -- surface of the methane and ethane lake called Ligeia Mare, an object appeared in 2013 just was not there in 2007. Subsequent observations in 2014 found the object remained -- but had changed! The featured image shows how the 20-km long object has appeared and evolved. Current origin speculative explanations include bubbling foam and floating solids,...

    Explanation: Higher than the highest mountain lies the realm of the aurora. Auroras rarely reach below 60 kilometers, and can range up to 1000 kilometers. Aurora light results from energetic electrons and protons striking atoms and molecules in the Earth's atmosphere. Somewhat uncommon, an auroral corona appears as a center point for a surrounding display and may occur when an aurora develops directly overhead, or when auroral rays are pointed nearly toward the observer. This picturesque but brief green and purple aurora exhibition occurred last month high above Kvalřya, Tromsř, Norway. The Sessřyfjorden fjord runs through the foreground, while numerous...

    Explanation: What causes sprite lightning? Mysterious bursts of light in the sky that momentarily resemble gigantic jellyfish have been recorded for over 25 years, but their root cause remains unknown. Some thunderstorms have them -- most don't. Recently, however, high speed videos are better detailing how sprites actually develop. The featured video is fast enough -- at about 10,000 frames per second -- to time-resolve several sprite "bombs" dropping and developing into the multi-pronged streamers that appear on still images. Unfortunately, the visual clues provided by these videos do not fully resolve the sprite origins mystery. They do indicate to...

    A Chinese pharmaceutical firm that has links with the country's military has developed an experimental Ebola drug. It is hoping federal authorities will immediately grant its approval so it can be marketed the soonest. Sihuan Pharmaceutical Holdings Group Ltd developed the drug called JK-05, along with the Institute of Microbiological Epidemiology, a part of the Academy of Military Medical Sciences. It has been approved but only for emergency military purposes. Sihuan also admitted during an investor call last week it has yet to undergo clinical trials. The firm said it is working to have the tests started, but if possible...

    The Ebola vaccine that Canada has developed has started its human clinical trials, Health Minister Rona Ambrose announced. Authorities will test the VSV-EBOV vaccine on a small group of people to assess its safety, determine the appropriate dosage and identify any side effects. So far, the vaccine has shown a 100 per cent success rate in animals, Ambrose said. A total of 20 vials of the experimental vaccine have been supplied for use in the trial. It was developed by scientists at the Public Health Agency of Canada's National Microbiology Laboratory (NML). The 20 healthy volunteers at the Walter Reed...

    The first Dallas health care worker with Ebola, Nina Pham, is in "improved condition today," and the second Dallas health care worker with Ebola is "ill but clinically stable," CDC Director Dr. Tom Frieden said Wednesday. Frieden said it's still to be determined whether Pham will be transferred to another facility; Frieden earlier said the second patient will be transferred to Emory University Hospital.

    UN officials admit that unless the international community can get Ebola under control by Christmas, the world will face an "unprecedented" situation for which there are no plans to deal with. From Sky News: "The WHO advises within 60 days we must ensure 70% of infected people are in a care facility and 70% of burials are done without causing further infection," said Anthony Banbury, the UN's deputy ebola coordinator. "We need to do that within 60 days from 1 October. If we reach these targets then we can turn this epidemic around." But Mr Banbury told the UN Security...

    (CNN) -- It can be exhausting nursing a child through a nasty bout with the flu, so imagine how 22-year-old Fatu Kekula felt nursing her entire family through Ebola. Her father. Her mother. Her sister. Her cousin. Fatu took care of them all, single-handedly feeding them, cleaning them and giving them medications. And she did so with remarkable success. Three out of her four patients survived. That's a 25% death rate -- considerably better than the estimated Ebola death rate of 70%.
