Ferroelectric crystals display a macroscopic electric polarization, a superposition of many dipoles at the atomic scale which originate from spatially separated electrons and atomic nuclei. The macroscopic polarization is expected to change when the atoms are set in motion but the connection between polarization and atomic motions has remained unknown.
Things are getting real for researchers in the UC Santa Barbara John Martinis/Google group. They are making good on their intentions to declare supremacy in a tight global race to build the first quantum machine to outperform the world's best classical supercomputers.
But what is quantum supremacy in a field where horizons are being widened on a regular basis, in which teams of the brightest quantum computing minds in the world routinely up the ante on the number and type of quantum bits ("qubits") they can build, each with their own range of qualities?
Immunotherapies are treatments that stimulate a patient's immune cells to attack the tumor. They can be very effective in melanoma - a common and aggressive form of skin tumor - but still fail in the majority of the patients. To address this, researchers are trying to identify the factors that enable successful immunotherapy, as well as those that may limit it. The ultimate goal is to open new avenues for immunotherapies that are more broadly effective in melanoma, and potentially other cancer types.
PHILADELPHIA - A new type of cancer vaccine has yielded promising results in an initial clinical trial conducted at the Perelman School of Medicine at the University of Pennsylvania and the Abramson Cancer Center of the University of Pennsylvania. The personalized vaccine is made from patients' own immune cells, which are exposed in the laboratory to the contents of the patients' tumor cells, and then injected into the patients to initiate a wider immune response.
ANN ARBOR--In an advance that could grime-proof phone screens, countertops, camera lenses and countless other everyday items, a materials science researcher at the University of Michigan has demonstrated a smooth, durable, clear coating that swiftly sheds water, oils, alcohols and, yes, peanut butter.
Science has yet to unravel a complete understanding of the brain and all its intricate workings. It's not for lack of effort.
Over many decades, multiple research studies have sought to understand the dizzying "talk," or interconnectivity, between thousands of microscopic entities in the brain, in particular, neurons. The goal: to one day arrive at a complete brain "mapping" -- a feat that could unlock tremendous therapeutic potential.
Eye drops developed by UBC researchers could one day treat glaucoma while you sleep - helping to heal a condition that is one of the leading causes of blindness around the world.
"Medicated eye drops are commonly used to treat glaucoma but they're often poorly absorbed. Less than five per cent of the drug stays in the eye because most of the drops just roll off the eye," said lead researcher Vikramaditya Yadav, a professor of chemical and biological engineering, and biomedical engineering at UBC.
Engineers at the University of California San Diego have developed a miniature, ultra-low power injectable biosensor that could be used for continuous, long-term alcohol monitoring. The chip is small enough to be implanted in the body just beneath the surface of the skin and is powered wirelessly by a wearable device, such as a smartwatch or patch.
It's still easy to tell computer-simulated motions from the real thing - on the big screen or in video games, simulated humans and animals often move clumsily, without the rhythm and fluidity of their real-world counterparts.
(PHILADELPHIA) -- The most common type of lung cancer, non-small cell lung cancer (NSCLC), continues to be difficult to treat, with five year survival rates of about 36 percent for stage 3A tumors. Jefferson College of Pharmacy researchers are developing a new treatment approach based on nanotechnology that was recently shown to be effective in mouse models of the disease. The research was published in the journal Molecular Pharmaceutics.
