“[Einstein] dreamt that he was riding a sled down a steep, snowy slope and, as he approached the speed of light in his dream, the colors all blended into one. He spent much of his career, inspired by that dream, thinking about what happens at the speed of light.”

For the first time, researchers have used light to control the shape of nanoparticles and create micron-size hollow shells from crystals of cuprous oxide (copper and oxygen). Such particles could have future applications as a low-cost catalyst to help pull excess carbon dioxide from the air, a way to improve microscopic imaging and more, says Bryce Sadtler, a chemist at Washington University in St. Louis and senior author of a study on the new method, published last October in Chemistry of Materials.

Hollowed-out microcrystals could lock away carbon.

Scientists create a very heavy atom with a very short life span.

In a wild galaxy over half a billion light-years away, astronomers have detected molecular oxygen. It’s only the third such detection ever outside the Solar System — and the first outside the Milky Way.

Oxygen is the third most abundant element in the Universe, behind hydrogen (naturally) and helium. So its chemistry and abundance in interstellar clouds are important for understanding the role of molecular gas in galaxies.

Astronomers have searched for oxygen again and again, using millimetre astronomy, which detects the radio wavelengths emitted by molecules; and spectroscopy, which analyses the spectrum to look for wavelengths absorbed or emitted by specific molecules.

One of the many ways scientists hope to improve the performance of today’s lithium batteries is by swapping out some of the liquid components for solid ones. Known as solid-state batteries, these experimental devices could greatly extend the life of electric vehicles and mobile devices by significantly upping the energy density packed inside. Scientists at MIT are now reporting an exciting advance toward this future, demonstrating a new type of solid-state battery architecture that overcomes some limitations of current designs.

In a regular lithium battery, a liquid electrolyte serves as the medium through which the lithium ions travel back and forth between the anode and cathode as the battery is charged and discharged. One problem is that this liquid is highly volatile and can sometimes result in battery fires, like those that plagued Samsung’s Galaxy Note 7 smartphone.

Replacing this liquid electrolyte for a solid material wouldn’t just make batteries safer and less prone to fires, it could also open up new possibilities for other key components of the battery. The anode in today’s lithium batteries is made from a mix of copper and graphite, but if it were made of pure lithium instead, it could break the “energy-density bottleneck of current Li-ion chemistry,” according to a recent study published in Trends in Chemistry.

A collaboration between McMaster and Harvard researchers has generated a new platform in which light beams communicate with one another through solid matter, establishing the foundation to explore a new form of computing.

Their work is described in a paper published today in the Proceedings of the National Academy of Sciences.

Kalaichelvi Saravanamuttu, an associate professor of Chemistry and Chemical Biology at McMaster, explains that the technology brings together a form of hyrdrogel developed by the Harvard team with light manipulation and measurement techniques performed in her lab, which specializes in the chemistry of materials that respond to light.

RNA secondary structure is critical to RNA regulation and function. We report a new N3-kethoxal reagent that allows fast and reversible labeling of single-stranded guanine bases in live cells. This N3-kethoxal-based chemistry allows efficient RNA labeling under mild conditions and transcriptome-wide RNA secondary structure mapping. The authors designed a chemical probe, azido-kethoxal, to specifically label guanosine in single-strand RNAs in live cells that could be used to determine transcriptome-wide RNA secondary structures.
