    Supercomputers are a crucial research tool for medicine, aviation, robots and weapons, but there are only three dominant players: The US, Japan and China. Europe has had enough of that situation, however, and announced plans to spend up to $1.2 billion to develop its own technology. The aim is to develop its own exascale machines (that can do a billion billion calculations per second) by 2022-23. "It is a tough race and today the EU is lagging behind," said EC comissioner Andrus Ansip.

    France has backed up statements that it's willing to reward America's climate researchers now that the US has backed out of the Paris global warming accord. President Emmanuel Macron handed out 13 of 18 "Make our Planet Great Again" grants worth millions of euros to US-based scientists. "You will now settle in, develop projects, enrich French, European research, because we've decided to give even bigger resources and to fully recognize what you are doing," Macron said in a speech at Paris startup hub Station F.

    Today, over a dozen federal agencies released the Climate Science Special Report, which is a product of the National Climate Assessment -- a congressionally mandated review that takes place every four years. In it, hundreds of scientists from dozens of government agencies and academic institutions present evidence that supports the existence of a human-caused warming planet and all of the consequences that come with it. "This assessment concludes, based on extensive evidence, that it is extremely likely that human activities, especially emissions of greenhouse gases, are the dominant cause of the observed warming since the mid-20th century," the report stated. "For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence."

    Gene-edited human embryos are offering new insights into the earliest stages of development, and could reduce the risk of miscarriage at the outset of pregnancy. In a new study, researchers from the UK's Francis Crick Institute used CRISPR Cas9 to block a gene (known as OCT4) in human embryos. By stopping it from functioning, the researchers saw that it no longer produced its resulting protein (also called OCT4). As a result, the human embryos ceased to attach or grow sufficiently. Their findings, published in the journal Nature, illustrate the importance of the gene in human development.

    That 3D rendering up there is a new telescope from the National Science Foundation that promises to solve the mysteries of the universe -- or at least take some truly big pictures. Fitted with a 3,200 megapixel camera, the Large Synoptic Survey Telescope will be the largest digital camera in the world. Once operational, it will scan the entire night sky a few times a week for ten years and is expected to provide scientists unprecedented access to previously inscrutable parts of the cosmos. The camera will literally shed light on dark energy that is believed to accelerate the expansion of the universe, but has long evaded definitive probes. Apart from capturing images of exploding supernovae at an unfathomable distance, it can detect and track asteroids in our planet's vicinity.

    Convinced that there's got to be life on other planets? You're not alone in the universe -- in fact, many NASA scientists agree with you. And a panel convened recently by the space agency (see the video below) believes that finding it could happen soon, too -- perhaps "in twenty years" -- thanks to incoming telescope technology. Recent projects, like the Kepler Telescope, Dark Energy Survey and the Very Large Telescope have detected the presence of planets and even their atmospheres. But astronomers are even more excited about future projects like the Transiting Exoplanet Surveying Satellite (TESS) and James Webb Space Telescope, set to launch in 2017 and 2018, respectively.

  • Researchers create working quantum bit in silicon, pave way for PCs of the future

    If you've been paying attention, you know the quantum computing revolution is coming -- and so far the world has a mini quantum network, not to mention the $10,000 D-Wave One, to show for it. Researchers from the University of Melbourne and University College, London, have now developed the "first working quantum bit based on a single atom of silicon." By measuring and manipulating the magnetic orientation, or spin, of an electron bound to a phosphorus atom embedded in a silicon chip, the scientists were able to both read and write information, forming a qubit, the basic unit of data for quantum computing. The team used a silicon transistor, which detects the electron's spin and captures its energy when the spin's direction is "up." Once the electron is in the transistor, scientists can change its spin state any way they choose, effectively "writing" information and giving them control of the quantum bit. The next step will be combing two qubits into a logic step, with the ultimate goal being a full-fledged quantum computer capable of crunching numbers, cracking encryption codes and modeling molecules that would put even supercomputers to shame. But, you know, baby steps.

    Are animations of Curiosity's Mars landing not enough to feed your space exploration appetite? Try this on for size: a group of scientists from the Harvard-Smithsonian Center for Astrophysics and the Heidelberg Institute for Theoretical Studies have generated what's billed as a full-fledged simulation of the universe. Arepo, the software behind the sim, took the observed afterglow of the big bang as its only input and sped things up by 14 billion years. The result was a model of the cosmos peppered with realistically depicted galaxies that look like our own and those around us. Previous programs created unseemly blobs of stars instead of the spiral galaxies that were hoped for because they divided space into cubes of fixed size and shape. Arepo's secret to producing accurate visualizations is its geometry; a grid that moves and flexes to mirror the motions of dark energy, dark matter, gasses and stars. Video playback of the celestial recreation clocks in at just over a minute, but it took Harvard's 1,024-core Odyssey super computer months to churn out. Next on the group's docket is tackling larger portions of the universe at a higher resolution.

    Recycling wastewater to generate energy has turned up noses before, but researchers at Oregon State University have developed a microbial fuel cell that can create 10 to 50, or even 100 times more electricity per volume than similar technologies. After refining the tech for several years using new materials, techniques and selecting better microbes, the team can now extract two kilowatts per cubic meter of refuse. As bacteria oxidizes organic matter, electrons -- rather than the hydrogen or methane that other methods rely upon -- are produced and run from an anode to a cathode within the device to create an electric current. Once implementation costs are cut down, the technology could power waste treatment plants and enable them to sell excess electricity. The contraption isn't just for processing what comes out of the porcelain throne -- it can also utilize materials ranging from grass straw to beer brewing byproducts. For now, however, the cell will tackle a pilot study before it inches closer to your local brewery or water treatment facility.

    Researchers at the University of Tennessee's Center for Laser Applications have developed a femtosecond laser that can non-invasively diagnose, map, irradiate and burn cancerous tumors. Utilizing a beam that pulses at one-quadrillionth of a second, the technology is able to seek out growths and obliterate them with an increased burst of intensity. "Using ultra-short light pulses gives us the ability to focus in a well confined region and the ability for intense radiation," says Associate Professor of Physics Christian Parigger. "This allows us to come in and leave a specific area quickly so we can diagnose and attack tumorous cells fast." The swift, precise technique can avoiding heating up adjacent, healthy tissues and has potential for use in outpatient procedures, particularly for people afflicted with brain tumors. For now, however, the scientists are working with the non-profit University of Tennessee Research Foundation to bring their tech to market. Roll past the jump for the press release and a glimpse of the laser in action.

    In an effort to recreate the fusion reaction that occurs in start formation, the National Ignition Facility in Livermore, CA has been building up to some extremely powerful laser shots. Back in March, researchers fired off 411 terawatts, and we know that kind of power doesn't come cheap. NIF's latest test shot, fired July 5th, set a new record with 192 lasers producing more than 500 trillion watts of peak power and 1.85 MJ of ultraviolet laser light. Mind you, that's more than a thousand times more energy than the United States uses at any given moment, not to mention a hundred times more power than other lasers can fire consistently. More record-setting shots are sure to come, and in addition to enabling research on harnessing nuclear fusion, NIF's mega-lasers are helping inform the design of new laser facilities being built in China, Japan, Russia, France and the UK.

  • Scientists bend gamma rays, could neuter radioactive waste (update: more credit)

    Bending most light is easy; bending it in gamma ray form, however, has often been deemed impossible given how hard it is for electrons to react to the extreme frequencies. LMU Munich scientist Dietrich Habs and his Institut Laue-Langevin teammate Michael Jentschel have proven that assumption wrong: an experiment in blasting a silicon prism has shown that gamma rays will refract just slightly through the right material. If a lens is made out of a large-atom substance like gold to bend the rays further, the researchers envision focused beams of energy that could either detect radioactive material or even make it inert by wiping off neutrons and protons. In theory, it could turn a nuclear power plant's waste harmless. A practical use of the technology is still some distance off -- but that it's even within sight at all just feels like a breakthrough. Update: The research also involved the Max Planck Institute of Quantum Optics' Marc Günther. Thank you, Dr. Günther.

    Ever feel like your phone is taking an awfully long time to register that swipe to unlock? Well, scientists from Imperial College London and King Abdullah University of Science and Technology are developing a solution that could mean faster response times. By combining polymer semiconductors and small molecules into a composite material to make organic thin-film transistors -- a process known as composite collaboration -- they found a way to increase the speed of the electrical charge moving through a device's components. The end result could someday be a smartphone that reacts to your touch much more quickly than your current handset. If you're so inclined, jump below the break to the presser for a more in-depth explanation.

    A team of German researchers is working on technology that could let you ski all day without worrying about your smartphone battery, says a report in GlobalPost. Scientists from the Fraunhofer Institute in Berlin, TEXSYS and the Technical University in Berlin have created a solar helmet that charges your mobile device while you ski. The helmet has a curved solar panel skin, integrated headphones and a microphone so you can use your phone or mp3 player on the slopes. They've also designed a special set of gloves that can control your mobile device. Though it might not appeal to your casual, recreational skier, this solar system could be useful for adventurers who need extra juice for a long day mountaineering as well as mountain rescue teams who would appreciate the always-on communication.

    It took six years, but at long last, Anna Konda has a formidable firefighting partner. SAFFiR, also known as the Shipboard Autonomous Firefighting Robot, is being shaped by scientists at the Naval Research Laboratory. As the story goes, it's a humanoid robot that's being engineered to "move autonomously throughout the ship, interact with people, and fight fires, handling many of the dangerous firefighting tasks that are normally performed by humans." Outside of being stoic (and brawny) from tip to tip, it's also outfitted with multi-modal sensor technology for advanced navigation and a sensor suite that includes a camera, gas sensor, and stereo IR camera to enable it to see through smoke. We're told that its internal batteries can keep it cranking for a solid half-hour, while being capable of manipulating fire suppressors and throwing propelled extinguishing agent technology (PEAT) grenades. Wilder still, it'll be able to balance in "sea conditions," making it perfect for killing flames while onboard a ship. Of course, it's also being tweaked to work with a robotic team, giving it undercover powers to eventually turn the flames on the folks that created it. Paranoid? Maybe. But who are we to be too careful?Update: Turns out, the same Dr. Hong that we had on The Engadget Show is responsible for this guy as well. It's the next step in evolution of the CHARLI humanoid, and the two photos seen after the break are credited to RoMeLa: Robotics & Mechanisms Laboratory, Virginia Tech.

  • Cornell scientists perform optical illusion, herald invisibility through bending of light (video)

    Taken at face value, you'd almost think that Cornell scientists had successfully bent the fabric of time. With gobs of fiber optics at their disposal, the researchers have devised a method to distort light in a way that makes events in time undetectable to observers. Initial success in this Pentagon-backed invisibility project has cloaked an event for 40 trillionths of a second, leading Cornell scientists to tout, "You kind of create a hole in time where an event takes place. You just don't know that anything ever happened." The feat is performed by separating light into more fundamental wavelengths, first by slowing the red and speeding the blue. A resultant gap forms in the beam, which leaves a small window for subterfuge. Then, as the light passes through another set of fibers -- which slow the blue and speed the red -- light reaches the observer as if no disturbance had taken place at all. While the brilliant researchers ultimately imagine art thieves being able to pass undetected through museums with this method, the immediate challenge will be in prolonging the light gap. This could prove frustrating, however, due to the scattering and dispersion effects of light. As Cornell scientists dream of their ultimate heist, visual learners will most certainly want to check the video after the break.

    If the phrase "I solemnly swear I'm up to no good" means anything to you, you'll be happy to know that scientists have come one step closer to a Potter-style "invisibility cloak" so you can use your Marauder's Map to the fullest. With the help of carbon nanotubes, researchers have been able to make objects seem to magically vanish by using the same principle that causes mirages. As anyone who's been especially parched along Route 66 knows, optical illusions occur when heat changes the air's temperature and density, something that forces light to "bend," making us see all sorts of crazy things. Apply the same theory under water using nanotubes -- one molecule carbon coils with super high heat conductivity -- and scientists can make a sheet of the stuff "disappear." Remember, it only works underwater, so get your gillyweed ready and check out the video after the break.
