  • 'Volumetric' imaging method reveals chemical content

    A "chemical imaging" system that uses a special type of laser beam to penetrate deep into tissue might lead to technologies that eliminate the need to draw blood for analyses including drug testing and early detection of diseases such as cancer and diabetes.

  • For first time, researchers measure forces that align crystals and help them snap together

    Like two magnets being pulled toward each other, tiny crystals twist, align and slam into each other, but due to an altogether different force. For the first time, researchers have measured the force that draws them together and visualized how they swivel and align.

  • Photodielectric discovery brings new optical control to electronics

    Characters in some of the more futuristic science fiction films, like "Minority Report" and "Iron Man," control computer displays with slick and deliberate hand motions. In "Minority Report," the protagonist, played by Tom Cruise, uses gloves that glow at the fingertips and give him the power of virtual manipulation. The light seems to allow him to control the screen as if it were a touchscreen, but he's touching nothing but air.

  • New analysis of brain network activity offers unique insight into epileptic seizures

    Epilepsy is a complex neurological disorder that afflicts approximately 50 million people worldwide. Although this disease has been known to exist for centuries, the exact mechanism of its cardinal symptom, the epileptic seizure, remains poorly understood. In fact, roughly 25 percent of epileptic seizures can't be controlled by any of the therapies available today.

  • Novel technique reveals the 3-D structure and composition of powerful, custom-made high-temperature superconductors

    Some of the most promising and puzzling phenomena in physics play out on the nanoscale, where a billionth-of-a-meter shift can make or break perfect electrical conductivity.

  • New fiber optic probe brings endoscopic diagnosis of cancer closer to the clinic

    In an important step toward endoscopic diagnosis of cancer, researchers have developed a handheld fiber optic probe that can be used to perform multiple nonlinear imaging techniques without the need for tissue staining. The new multimodal imaging probe uses an ultrafast laser to create nonlinear optical effects in tissue that can reveal cancer and other diseases.

  • Tracking particles at the energy frontier

    A new age of exploration dawned at the start of Run 2 of the Large Hadron Collider, as protons began colliding at the unprecedented centre-of-mass energy of 13 TeV. The ATLAS experiment now frequently observes highly collimated bundles of particles (known as jets) with energies of up to multiple TeV, as well as tau-leptons and b-hadrons that pass through the innermost detector layers before decaying. These energetic collisions are prime hunting grounds for signs of new physics, including massive, hypothetical new particles that would decay to much lighter – and therefore highly boosted – bosons.

  • Control of molecular motion by metal-plated 3-D printed plastic pieces

    Many measurement techniques, such as spectroscopy, benefit from the ability to split a single beam of light into two in order to measure changes in one of them. The crucial device that separates the beam is the beam-splitter. These have been mostly limited to light beams, where one uses simply a partially reflective glass.

  • Move over, Superman! NIST method sees through concrete to detect early-stage corrosion

    When you suffer a fall, an on-the-field collision or some other traumatic blow, the first thing the doctor will do is take an X-ray, CT scan or MRI to determine if anything has been damaged internally. Researchers at the National Institute of Standards and Technology (NIST) are using the same principle, but in a more powerful form, to detect corrosion, the primary danger threatening the health of the steel framework within the nation's bridges, roads and other aging physical infrastructure.

  • Laser cooling a polyatomic molecule

    (Phys.org)—A team of researchers at Harvard University has successfully cooled a three-atom molecule down to near absolute zero for the first time. In their paper published in Physical Review Letters, the team describes how they achieved the feat and suggest that their technique could be modified to allow for cooling molecules with even more atoms.

  • 'Quantum simulator' facilitates research into theoretical supermaterials

    Physicists at Utrecht University have created a 'quantum simulator,' a model system to study theoretical prognoses for a whole new class of materials. These 'supermaterials' include graphene, which has a two-dimensional structure and unique characteristics. The experiments conducted in Utrecht not only confirm the theoretical physicists' predictions, but also provided new insights. They have discovered that at higher energy levels, a simple rectangular lattice has characteristics that are normally only observed in exotic materials. The results of their research are Published in Nature Physics of 24 April 2017.
