The charge-to-mass ratio — an important property of particles — can be measured by observing the oscillation of a particle in a magnetic field. Based on the new CERN’s experiment, there was no difference between the proton and the antiproton, with a four-fold improvement in the energy resolution compared with previous measurements. The work has implications for what is known as the weak equivalence principle –the idea that all particles will be affected by gravity in the same way, regardless of their mass and charge. The team used their findings to calculate that within about one part per million, antimatter and matter behave in the same way with respect to gravity. Using more stable magnetic fields and other approaches, the researchers plan to achieve measurements that are at least 10-100 times more precise than what they found so far. Source: EurekAlert!

Written By Andrew Tieu 5 days ago IN BRIEF A team of researchers from the USC Institute for Creative Technologies and the Imperial College London jointly developed a new method for capturing the impossibly subtle deformations in human skin. Capturing every last wrinkle and deformation of human skin is basically impossible for talented CG animators and sophisticated video capture systems alike. Those infinitely subtle ways the skin moves on a human face allows us to spot the differences between a real-life humans, and their CG counterpart—at least for now. The team of researcher has come up with a new way to capture the tiny details on the surface of various skin patches on an actor’s face at a resolution of 10 microns as they’re being stretched and deformed by a specially-designed rig. At that resolution the exact deformations of even individual skin pores is captured, and using custom software, the captured data can be mapped to the artificial skin of a CG character, making the emotions of the face so realistic you can’t tell human from computer human. Eventually the researchers hope to design a model that allows the system to perfectly simulate exactly how human skin deforms based on a person’s race, age, sex, and emotions, without requiring actors to be subjected to that face deforming contraption.

But its home, CERN, is working on a new linear accelerator just two meters long. The new CERN miniature linear accelerator is designed for hospitals and should be useful for imaging and treating cancer. According to CERN, the miniature accelerator is a radiofrequency quadrupole, which is a component found at the “start of all proton accelerator chains” that produce high-intensity beams. The mini accelerator can produce low-intensity beams grouped at a frequency of 750 MHz. That makes it well-suited for treating cancer with protons. The small size also means that it can be installed in hospitals to produce radioactive isotopes that can be used in medical imaging.

According to an MIT press release, it's "poised to become the next semiconductor for power electronics." A MIT spinout, Cambridge Electronics, has announced it will sell gallium nitride transistors and power electronic circuits. The pitch is that they could cut energy usage in applications like data centers, electric cars, and consumer devices. It can do this because it discovered a gallium nitride breakthrough which cocerces gallium nitride to not conduct by default. The first application is in power electronics — small devices in everything you use that convert electricity to higher or lower voltages and currents. Currently, power-electronic systems largely rely on silicon transistors, which are inefficient and give off heat. So Cambridge Electronics has developed gallium nitride transistors that sport one-tenth the resistance of silicon-based transistors, which has several implications: power electronics can be more efficient, faster, and most importantly, smaller. Imagine if your laptop power adapter was actually inside your laptop.

In a live keynote today, Intel and Micron announced 3D Xpoint, a new category of non-volatile memory that claims to be 1,000 times faster than the NAND architecture underlying most flash memory cards and solid state drives. The new architecture does without transistors entirely, relying on a bulk material property change to switch bits from a low-resistance to a high-resistance state. From there, memory cells are layered in an intricate three-dimensional checkerboard pattern that Intel researchers say is 10 times denser than conventional memory. The limitations of the new memory class are still unclear, but its earliest applications are likely to be in real-time data analysis, where fast access to large datasets is at a premium. Intel singled out fraud detection and disease tracking as likely early applications, but said the chip could also be used to power more immersive gaming experiences if brought to the PC.
