Rice disease-resistance discovery closes the loop for scientific integrity
UC Davis researchers here identify a protein in a crop-attacking bacterial disease, showing how the presence of the protein alerts the plant that a microbial invasion is in progress and allows the plant to launch a defensive immune response. The discovery is especially important because it corrects an earlier error, which in 2013 led this laboratory to publicly retract two important research releases.

Penn researchers discover new chiral property of silicon, with photonic applications
By encoding information in photons via their spin, 'photonic' computers could be orders of magnitude faster and efficient than their current-day counterparts. Likewise, encoding information in the spin of electrons, rather than just their quantity, could make 'spintronic' computers with similar advantages. University of Pennsylvania engineers and physicists have now discovered a property of silicon that combines aspects of all of these desirable qualities.

Smarter window materials can control light and energy
Chemical engineering professor Delia Milliron and her team have engineered two new advancements in electrochromic materials -- a highly selective cool mode and a warm mode -- not thought possible several years ago. The researchers are one step closer to delivering smart windows with a new level of energy efficiency.

Trapped light orbits within an intriguing material
Hexagonal boron nitride bends electromagnetic energy in unusual and potentially useful ways. Physicists recently found that nanoscale granules of the material can store light. Now they have shown that the trapped light, polariton rays, propagate along paths at fixed angles with respect to the atomic structure of the material and at certain 'magic' frequencies form simple closed orbits. The insight could guide the development of applications such as nanoresonators, hyperlenses or infrared photon sources.

Futuristic brain probe allows for wireless control of neurons
A study showed that scientists can wirelessly determine the path a mouse walks with a press of a button. Researchers created a remote controlled, next-generation tissue implant that allows neuroscientists to inject drugs and shine lights on neurons deep inside the brains of mice. The revolutionary device is described online in the journal Cell. Its development was partially funded by the National Institutes of Health.

Molecular fuel cell catalysts hold promise for efficient energy storage
In the quest for better, less expensive ways to store and use energy, platinum and other precious metals play an important role. They serve as catalysts to propel the most efficient fuel cells, but they are costly and rare. Now, a metal-free alternative catalyst for fuel cells may be at hand.

Bats do it, dolphins do it -- now humans can do it, too
Bats have been using sonar to navigate and communicate for ages, and now humans can do the same, thanks to lightweight and efficient ultrasound microphones and loudspeakers developed by UC Berkeley physicists. The devices owe their flat frequency response to graphene, which makes a stiff and responsive diaphragm far superior to those in today's ultrasound receivers and transmitters. Biologists can even slap one on a bat to record its nightly ultrasonic conversations.

Effective conversion of methane by a new copper zeolite
A new bio-inspired zeolite catalyst, developed by an international team with researchers from Technische Universität München, Eindhoven University of Technology and University of Amsterdam, might pave the way to small scale 'gas-to-liquid' technologies converting natural gas to fuels and starting materials for the chemical industry. Investigating the mechanism of the selective oxidation of methane to methanol they identified a trinuclear copper-oxo-cluster as the active center inside the zeolite micropores.

Researchers successfully target 'Achilles' heel' of MERS virus
Researchers studying the Middle East Respiratory Syndrome, or MERS, have found molecules that shut down the activity of an essential enzyme in the virus and could lead the way to better treatments for those infected. The team identified molecules that inhibit an enzyme essential to MERS virus replication, and also discovered a characteristic of the enzyme that is very different from other coronaviruses.

The secrets of secretion
Living tissues rely on their ability to package, transport and secrete liquid, where and when it's needed. Nature's secretion system is responsive, self-regulatory and intrinsically linked with its surroundings. Synthetic systems haven't been able to replicate that complexity -- until now. A new system developed at Harvard spontaneously releases only enough fluid to replace what is lost on the surface.

Penn research simplifies recycling of rare-earth magnets
Researchers at the University of Pennsylvania have now pioneered a process that could enable the efficient recycling of two rare-earth metals, neodymium and dysprosium. These elements comprise the small, powerful magnets that are found in many high-tech devices. In contrast to the massive and energy-intensive industrial process currently used to separate rare earths, the Penn team's method works nearly instantaneously at room temperature and uses standard laboratory equipment.

A new way to image surfaces on the nanoscale
A multi-institutional team of scientists, including a Northwestern University professor of materials science and engineering, has taken an important step in understanding where atoms are located on the surfaces of rough materials, information that could be very useful in diverse commercial applications, such as developing green energy and understanding how materials rust. The team has developed a new imaging technique that uses atomic resolution secondary electron images in a quantitative way to determine the arrangement of atoms on the surface.
