New DNA synthesis technique promises rapid, high-fidelity DNA printing
Today, DNA is synthesized as an organic chemist would, using toxic chemicals and error-prone steps that limit accuracy and thus length to about 200 base pairs. UC Berkeley and Berkeley Lab researchers have adapted a human enzyme that makes DNA in water to a repetitive process for adding base pairs. Initial tests show that the technique promises to make oligonucleotides 10 times longer, the size of small genes, faster, cheaper and without toxic waste.

Rutgers physicists create new class of 2D artificial materials
In 1965, a renowned Princeton University physicist theorized that ferroelectric metals could conduct electricity despite not existing in nature. For decades, scientists thought it would be impossible to prove the theory by Philip W. Anderson, who shared the 1977 Nobel Prize in physics. It was like trying to blend fire and water, but a Rutgers-led international team of scientists has verified the theory and their findings are published online in Nature Communications.

Is there an end to the periodic table? MSU professor explores its limits
As the 150th anniversary of the formulation of the Periodic Table of Chemical Elements looms, a Michigan State University professor probes the table's limits in a recent Nature Physics Perspective. In 2016, four new elements were added to it: nihonium, moscovium, tennessine, and oganesson. It took a decade and worldwide effort to confirm these last four elements. And now scientists wonder: how far can this table go?

Salt Lake's light rail trains are air quality sleuths
The TRAX project is the only known transit-based mobile air quality network in North America. Some results are unsurprising, such as spikes of carbon dioxide and nitrogen dioxide, byproducts of gasoline combustion, at street intersections. But the sensors also found methane emissions patterns that didn't correlate to daytime working hours, suggesting possible fugitive methane leaks.

Groundwater pumping can increase arsenic levels in irrigation and drinking water
Pumping an aquifer to the last drop squeezes out more than water. A Stanford study finds it can also unlock dangerous arsenic from buried clays -- and reveals how sinking land can provide an early warning and measure of contamination.

Physicists use terahertz flashes to uncover state of matter hidden by superconductivity
A research team led by Jigang Wang of Iowa State University and the Ames Laboratory has developed a new quantum switching scheme that gives them access to new and hidden states of matter. If researchers can learn to control the hidden state, further stabilize it and determine whether it's suitable for quantum logic operations, it could allow researchers to use it for quantum computing and other practical functions. The journal Nature Materials has just published a paper about the discovery.

Rutgers-led research could lead to more efficient electronics
A Rutgers-led team of physicists has demonstrated a way to conduct electricity between transistors without energy loss, opening the door to low-power electronics and, potentially, quantum computing that would be far faster than today's computers. Their findings, which involved using a special mix of materials with magnetic and insulator properties, are published online in Nature Physics.

UMD-led study shows how Earth slows the solar wind to a gentle breeze
A University of Maryland-led study describes the first observations of the process of electron heating in Earth's bow shock. The researchers found that when the electrons in the solar wind encounter the bow shock, they momentarily accelerate to such a high speed that the electron stream becomes unstable and breaks down. This breakdown process robs the electrons of their high speed and converts the energy to heat.

Microscopy advance reveals unexpected role for water in energy storage material
A material with atomically thin layers of water holds promise for energy storage technologies, and researchers have now discovered that the water is performing a different role than anyone anticipated. The finding was possible due to a new atomic force microscopy method that measures the sub-nanoscale deformation rate in the material in response to changes in the material caused by energy storage.

Columbia researchers squeeze light into nanoscale devices and circuits
Columbia investigators have made a major breakthrough in nanophotonics research, with their invention of a novel 'home-built' cryogenic near-field optical microscope that has enabled them to directly image, for the first time, the propagation and dynamics of graphene plasmons at variable temperatures down to negative 250 degrees Celsius. If researchers can harness this nanolight, they will be able to improve sensing, subwavelength waveguiding, and optical transmission of signals.

A better way to control crystal vibrations
The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations travel through the crystalline structure determine fundamental properties of the material. Now, researchers have shown that by swapping out just a small fraction of a material's atoms with atoms of a different element, they can control the speed and frequencies of these vibrations

Self-assembling 3D battery would charge in seconds
A cross-campus collaboration led by Ulrich Wiesner, professor of engineering in the at Cornell University, addresses this demand with a novel energy storage device architecture that has the potential for lightning-quick charges. The group's idea: Instead of having the batteries' anode and cathode on either side of a nonconducting separator, intertwine the components in a self-assembling, 3D gyroidal structure, with thousands of nanoscale pores filled with the elements necessary for energy storage and delivery.

Supercomputing the emergence of material behavior
Chemists at the University of California, San Diego designed the first artificial protein assembly (C98RhuA) whose conformational dynamics can be chemically and mechanically toggled. The Maverick GPU-based supercomputer at the Texas Advanced Computing Center simulated the system through an allocation on NSF-funded XSEDE, the Extreme Science and Engineering Discovery Environment. The research, published in April 2018 in Nature Chemistry, could help create new materials for renewable energy, medicine, water purification, and more.

New device could increase battery life of electronics by a hundred-fold
Among the chief complaints for smartphone, laptop and other battery-operated electronics users is that the battery life is too short and -- in some cases -- that the devices generate heat. Now, a group of physicists led by Deepak K. Singh, associate professor of physics and astronomy at the University of Missouri, has developed a device material that can address both issues. The team has applied for a patent for a magnetic material that employs a unique structure -- a 'honeycomb' lattice that exhibits distinctive electronic properties.
