New study shows bacteria can use magnetic particles to create a 'natural battery'
New research shows bacteria can use tiny magnetic particles to effectively create a 'natural battery.' According to work published in journal Science on March 27, the bacteria can load electrons onto and discharge electrons from microscopic particles of magnetite. This discovery holds out the potential of using this mechanism to help clean up environmental pollution, and other bioengineering applications.

Can perovskites and silicon team up to boost industrial solar cell efficiencies?
A collaboration between the Massachusetts Institute of Technology and Stanford University may be poised to shake things up in the solar energy world. By exploring ways to create solar cells using low-cost manufacturing methods, the team has developed a novel prototype device that combines perovskite with traditional silicon solar cells into a two-terminal 'tandem' device.

UW scientists build a nanolaser using a single atomic sheet
University of Washington scientists have built a new nanometer-sized laser using a semiconductor that's only three atoms thick. It could help open the door to next-generation computing that uses light, rather than electrons, to transfer information.

Global water use may outstrip supply by mid-century
Population growth could cause demand for water to outpace supply by mid-century if current use levels continue. But it wouldn't be the first time this has happened, a Duke study finds. Using a mathematical model to analyze historic data, the researchers identified a regularly recurring pattern of time periods when demand for water outstripped supply, and shortages were resolved by technological advancements. The model projects a similar period of innovation could occur in coming decades.

Catching and releasing tiny molecules
Employing an ingenious microfluidic design that combines chemical and mechanical properties, a team of Harvard scientists has demonstrated a new way of detecting and extracting biomolecules from fluid mixtures. The approach requires fewer steps, uses less energy, and achieves better performance than several techniques currently in use and could lead to better technologies for medical diagnostics and chemical purification.

Rutgers University chemistry research holds great promise for advancing sustainable energy
Researchers have developed a compound, Ni5P4 (nickel-5 phosphide-4), that has the potential to replace platinum in two types of electrochemical cells: electrolyzers that make hydrogen by splitting water through hydrogen evolution reaction (HER) powered by electrical energy, and fuel cells that make electricity from combining hydrogen and oxygen.

A new method for making perovskite solar cells
Researchers have come up with a new way of making thin perovskite films for solar cells. The method forms perovskite crystals at room temperature, which could be helpful in mass production settings. The technique is especially well suited to make ultra-thin, semitransparent films, which could be used in photovoltaic windows.

Uncovering the secrets of super solar power perovskites
In a scant five years of development, hybrid perovskite solar cells have attained power conversion efficiencies that took decades to achieve with the top-performing conventional materials, but scientists have lacked a clear understanding of the precise goings on at the molecular level. New findings by University of Utah physicists help fill that void.

Catalyst destroys common toxic nerve agents quickly
Northwestern University scientists have developed a robust new material, inspired by biological catalysts, that is extraordinarily effective at destroying toxic nerve agents that are a threat around the globe. The material, a zirconium-based metal-organic framework, degrades in minutes one of the most toxic chemical agents known to mankind: Soman, a more toxic relative of sarin. Computer simulations show the MOF should be effective against other easy-to-make agents, such as VX.

Transport molecule forms a protective structure to guide proteins to cell membrane
The molecular complex that guides an important class of proteins to correct locations in cell membranes does so by forming a dimeric structure with a protective pocket. This structure shields tail-anchored membrane proteins -- which have roles in a wide variety of cellular functions from neurotransmitter release to insulin production -- from harmful aggregation or misfolding as they move through the inner environment of a cell. The findings clarify the mechanism behind a fundamental biological process.

Miscanthus-based ethanol boasts bigger environmental benefits, higher profits
A recent study simulated a side-by-side comparison of the yields and costs of producing ethanol using miscanthus, switchgrass, and corn stover. The fast-growing energy grass miscanthus was the clear winner. Models predict that miscanthus will have higher yield and profit, particularly when grown in poor-quality soil. It also outperformed corn stover and switchgrass in its ability to reduce greenhouse gas emissions.

UCLA physicists offer a solution to the puzzle of the origin of matter in the universe
Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry, which favors matter to a very small degree, has puzzled scientists for many years. UCLA physicists offer a possible solution to the mystery of the origin of matter in the universe.
