  • Atomic bond types discernible in single-molecule images

    A pioneering team from IBM in Zurich has published single-molecule images so detailed that the type of atomic bonds between their atoms can be discerned. The same team took the first-ever single-molecule image in 2009 and more recently published images of a molecule shaped like the Olympic rings. The new work opens up the prospect of studying imperfections in the "wonder material" graphene or plotting where electrons go during chemical reactions. The images are published in Science. The team, which included French and Spanish collaborators, used a variant of a technique called atomic force microscopy, or AFM. AFM uses a...

    A narrative has developed over the past several years that the Republican Party is anti-science. Recently, thanks to the ignorant remarks about rape made by Rep. Todd Akin, the Democrats have seized the opportunity to remind us that they are the true champions of science in America. But is it really true? No. As we thoroughly detail in our new book, "Science Left Behind," Democrats are willing to throw science under the bus for any number of pet ideological causes – including anything from genetic modification to vaccines. Consider California’s Proposition 37, which would require genetically modified food to carry...

    Speed of light may have changed recently 19:00 30 June 04 The speed of light, one of the most sacrosanct of the universal physical constants, may have been lower as recently as two billion years ago - and not in some far corner of the universe, but right here on Earth. The controversial finding is turning up the heat on an already simmering debate, especially since it is based on re-analysis of old data that has long been used to argue for exactly the opposite: the constancy of the speed of light and other constants. A varying speed of light...

The Phoenix cluster is spewing out the celestial bodies at the highest rate ever observed for the middle of a galaxy cluster; it's the most powerful producer of X-rays of any known cluster; it's one of the most massive of its kind; and the rate of hot gas cooling in the central regions is the largest ever observed.

    Scientists at CERN's Large Hadron Collider say they just temporarily created the hottest man-made temperature by colliding two lead ions. According to a source working on the project, the collision sprung loose a plasma "soup" of sub-atomic gluons and quarks at an estimated temperature of 5.5-trillion-degrees Celsius. We won't know just how hot the plasma was for at least a few weeks because the measurements are very delicate and have to be converted to degrees. The consensus seems to be that it will shatter the previous record, which was about 4 trillion degrees.The craziest thing is that this might not...

In this paper in Nature (hooray for free access!), they explain that their 201 x 201 pixel images captured around 2,500 different entangled quantum states. The entangled photons were imaged using different lens configurations to capture correlations of position and momentum – the characteristics (to shorthand Heisenberg’s uncertainty principle) that mutually preclude excessive knowledge about a given quantum system. From the 100,000 images taken by their setup (pictured*), the scientists say they were able to observe 2,500 states which they described as...

    ANN ARBOR — Astrophysicists have detected, for the first time, the oscillating signal that heralds the last gasps of a star falling victim to a previously dormant supermassive black hole. Led by researchers at the University of Michigan, the team documented the event with the Suzaku and XMM-Newton orbiting X-ray telescopes. These instruments picked up semi-regular blips in the light from a numerically-named galaxy 3.9 billion light years away in the northern constellation Draco the dragon. The blips, scientifically known as “quasiperiodic oscillations,” occurred steadily every 200 seconds, but occasionally disappeared. Such signals have often been detected at smaller black...

In much the way an iron bar can suddenly become a magnet when cooled below a certain temperature, space itself acquired a new feature. Instead of a magnetic field, space was filled with a new forcelike field -- since named for Higgs. Other physicists worked out similar scenarios at about the same time, and later work showed how the Higgs phase transition could explain the distinct identities of two of nature's basic...

    A simulation of the early universe using string theory may explain why space has three observable spatial dimensions instead of nine. The leading mathematical explanation of physics goes beyond modern particle theory by positing tiny bits of vibrating string as the fundamental basis of matter and forces. String theory also requires that the universe have six or more spatial dimensions in addition to the ones observed in everyday life. Explaining how those extra dimensions are hidden is a central challenge for string theorists... In the simulation, the universe starts off as a tiny blob of strings that is symmetric in...

A new study led by Princeton scientists shows that this happens because of a process known as quantum entanglement that determines the mass of electrons moving in a crystal. The discovery can help improve understanding of how certain materials become superconducting, which may have applications in areas such as power network efficiency and computing speed.

But a new effort from that same team demolishes that record, beaming the photons over 97 kilometers. The physicists, working from the University of Science and Technology of China in Shanghai, have again taken advantage of quantum entanglement for the purposes of moving an object from one place to another without ever moving in the space between. According to Technology Review, "The idea is not that the physical object is...

    Inside Science Minds presents an ongoing series of guest columnists and personal perspectives presented by scientists, engineers, mathematicians, and others in the science community showcasing some of the most interesting ideas in science today.(ISM) -- Our universe may exist inside a black hole. This may sound strange, but it could actually be the best explanation of how the universe began, and what we observe today. It's a theory that has been explored over the past few decades by a small group of physicists including myself. Successful as it is, there are notable unsolved questions with the standard big bang theory,...

    A re-analysis of radio telescope observations from three countries has yielded a surprising result: nearby galaxies harbour one-third more hydrogen than had previously been estimated. While nothing like enough matter to solve physics’ “dark matter” problem, the work by CSIRO astronomer Dr Robert Braun (chief scientist at the agency’s Astronomy and Space Science division in Sydney) also helps explain why the rate of star formation has slowed down. While there’s more hydrogen than astronomers had thought, its distribution makes star formation more difficult. Andromeda – the galaxy headed for a catastrophic collision with our own in about four billion years...

    Precocious young physicist Aisha Mustafa just patented a new system that could propel spacecrafts to the final frontier without using a drop of fuel. In short her system taps one of the odder facets of quantum theory, which posits that space isn't really a vacuum. It's really filled with particles and anti-particles that exist for infinitesimally small periods of time before destroying each other. Mustafa thinks she can harness them to create propulsion, resulting in space craft that need little-to-no fuel to maneuver around in space. Fast Company reports: Mustafa invented a way of tapping this quantum effect via what's...

    Looking at the fundamental properties of matter can take some serious computing grunt. Take the calculation needed to help understand kaon decay – a subatomic particle interaction that helps explain why the universe is made of matter rather than anti-matter: it soaked up 54 million processor hours on Argonne National Laboratory’s BlueGene/P supercomputer near Chicago, along with time on Columbia University’s QCDOC machine, Fermi National Lab’s USQCD (the US Center for Quantum Chromo-Dynamic) Ds cluster, and the UK’s Iridis cluster at the University of Southampton and the DIRAC facility. The reason so much iron was needed: the kaon decay spans...

    Whether you're a Trekkie or not, you have to admit that there's some sense of wonder toexploring the stars and trying to find life on distant planets. Of course, the U.S.S. Enterprise is a fictional ship, but have you ever put in the thought as to what it would take to actually build it, and when we could get it done if we really put in the effort? The man behind the well-researched site buildtheenterprise.org has, and he's determined that a fully functional Enterprise is only 20 years away if we put in the effort.

    The so-called Republican brain, with its deep resistance to yielding before mere scientific evidence, has played an indispensable role in the making of modern science, long before the emergence of the Grand Old Party. A new term of political opprobrium has been loosed upon the world: anti-science. Like many terms of abuse, it is easier to convey its meaning by an illustration than by a rigorous definition. For example, “If those damn Republicans weren’t so anti-science, we might have a chance of dealing with global warming.” Here’s another example: “Those damn Republicans are so anti-science that they want to see...

    Explanation: What is all this fuss about the Higgs boson? The physics community is abuzz that a fundamental particle expected by the largely successful Standard Model of particle physics may soon be found by the huge Large Hadron Collider (LHC) at CERN in Europe. The term boson refers to a type of fundamental particle with similarities to the photon, while Higgs refers to Peter Higgs, a physicist who among others published research predicting the mechanism through which such a particle might act. The above animated cartoon explains in humorous but impressive detail why the Higgs boson is expected, and one...
