Refocusing research into high-temperature superconductors
Scientists around the globe are trying to understand the phenomenon of loss-free electric power transmission by high-temperature superconductors. Materials that exhibit this effect at room temperature would bear huge technical potential. Recently symmetry changes in the electronic phases of high-temperature superconductors near their transition temperature had been attributed to doping effects. But an international team of scientists has now discovered that solely spin dynamics of the electrons are responsible for these spontaneous changes.

Strict genomic partitioning by biological clock separates key metabolic functions
Much of the liver's metabolic function is governed by circadian rhythms -- our own body clock -- and UC Irvine researchers have now found two independent mechanisms by which this occurs.

Engineering a protein to prevent brain damage from toxic agents
New research may help prevent brain damage for those exposed to pesticides and chemical weapons. The work centers on proteins called phosphotriesterases, which are able to degrade chemicals known as organophosphates -- found in everything from industrial pesticides to sarin gas. They permanently bond to neurotransmitters in the brain, interfering with their ability to function and causing irreversible damage. The researchers re-engineered the protein to make it sufficiently stable to be used therapeutically.

Antarctic ice sheet is result of CO2 decrease, not continental breakup
Climate modelers from the University of New Hampshire have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decreased carbon dioxide levels. The finding counters a 40-year-old theory suggesting massive rearrangements of Earth's continents caused global cooling and the abrupt formation of the Antarctic ice sheet. It will provide scientists insight into the climate change implications of current rising global CO2 levels.

Supportive moms and sisters boost female baboon's rank

NSF grant to Wayne State supports new concept for manufacturing nanoscale devices
According to the National Science Foundation, nanotechnology is the creation and utilization of functional materials, devices, and systems with novel properties and functions. A major bottleneck in scaling up nanotechnology is the lack of manufacturing methods that connect different functional materials into one device. A research team led by Dr. Guangzhao Mao, professor of chemical engineering and materials science at Wayne State University, is seeking answers to this problem.

Exploring 3-D printing to make organs for transplants
Printing whole new organs for transplants sounds like something out of a sci-fi movie, but the real-life budding technology could one day make actual kidneys, livers, hearts and other organs for patients who desperately need them. In the ACS journal Langmuir, scientists are reporting new understanding about the dynamics of 3-D bioprinting that takes them a step closer to realizing their goal of making working tissues and organs on-demand.

Mapping the optimal route between 2 quantum states
As a quantum state collapses from a quantum superposition to a classical state or a different superposition, it will follow a path known as a quantum trajectory. In a new paper featured this week on the cover of Nature, scientists have shown that it is possible to track these quantum trajectories and compare them to a recently developed theory for predicting the most likely path a system will take between two states.

Finding quantum lines of desire
What paths do quantum particles, such as atoms or photons, follow through quantum state space? Kater Murch of Washington University in St. Louis has used an 'artificial atom' to continuously and repeatedly paths through quantum state space. From the cobweb of a million paths, a most likely path between two quantum states emerged, much as social trails emerge as people round off corners or cut across lawns between buildings.

UC San Diego's WIFIRE project helps firefighters get a jump on wildfires
In recent years, the number and scale of wildfires in the US has risen, threatening cities and forests, and at times forcing large-scale evacuations. Now, thanks to a multi-year, $2.65 million grant from the National Science Foundation, the University of California San Diego, and the University of Maryland have been building a cyberinfrastructure to better monitor, predict, and mitigate wildfires in the future.

Vision-correcting display makes reading glasses so yesterday
Researchers at UC Berkeley are developing vision-correcting displays that can compensate for a viewer's visual impairments to create sharp images without the need for glasses or contact lenses. The technology could potentially help those who currently need corrective lenses to use their smartphones, tablets and computers, and could one day aid people with more complex visual problems.

Superconductivity could form at high temperatures in layered 2-D crystals
An elusive state of matter called superconductivity could be realized in stacks of sheetlike crystals just a few atoms thick, new analysis determined. Electrons and 'holes' would accumulate in separate layers of a 2-D semiconductor compound in response to an electrical field forming a superfluid gas of indirect excitons. Counterflow superconductivity would result.
