There’s a lot we don’t know about the actinides. On the periodic table, this series of heavy, radioactive elements hangs at the bottom, and includes a host of mysterious substances that don’t naturally occur on Earth.

Among this cast of unknowns, berkelium looks to be even stranger than we realised. New experiments with this incredibly rare synthetic element have shown that its electrons don’t behave the way they should, defying quantum mechanics.

“It’s almost like being in an alternate universe because you’re seeing chemistry you simply don’t see in everyday elements,” says chemist Thomas Albrecht-Schmitt from Florida State University.

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry 2017 to Jacques Dubochet (University of Lausanne, Switzerland), Joachim Frank (Columbia University, New York, USA) and Richard Henderson (MRC Laboratory of Molecular Biology, Cambridge, UK) “for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution”.

We may soon have detailed images of life’s complex machineries in atomic resolution. The Nobel Prize in Chemistry 2017 is awarded to Jacques Dubochet, Joachim Frank and Richard Henderson for the development of cryo-electron microscopy, which both simplifies and improves the imaging of biomolecules. This method has moved biochemistry into a new era.

A picture is a key to understanding. Scientific breakthroughs often build upon the successful visualisation of objects invisible to the human eye. However, biochemical maps have long been filled with blank spaces because the available technology has had difficulty generating images of much of life’s molecular machinery. Cryo-electron microscopy changes all of this. Researchers can now freeze biomolecules mid-movement and visualise processes they have never previously seen, which is decisive for both the basic understanding of life’s chemistry and for the development of pharmaceuticals.

This substance is a complex natural polymer called lignin, and it is the second largest renewable carbon source on the planet after cellulose.

This natural abundance has drawn high interest from the to chemically convert into biofuels. And if plant life really does hold the building blocks for renewable fuels, it would seem that we are literally surrounded by potential energy sources everywhere green grows.

But untangling the complex chains of these polymers into components, which can be useful for liquid fuel and other applications ranging from pharmaceuticals to plastics, has presented an ongoing challenge to science and industry.

Light-activated nanoparticles, also known as quantum dots, can provide a crucial boost in effectiveness for antibiotic treatments used to combat drug-resistant superbugs such as E. coli and Salmonella, new University of Colorado Boulder research shows.

Multi-drug resistant pathogens, which evolve their defenses faster than new can be developed to treat them, cost the United States an estimated $20 billion in direct healthcare costs and an additional $35 billion in lost productivity in 2013.

CU Boulder researchers, however, were able to re-potentiate existing for certain clinical isolate infections by introducing nano-engineered dots, which can be deployed selectively and activated or de-activated using specific wavelengths of light.

In its secretive R&D department, Honda has been developing a bipedal disaster robot designed to climb through crumbled buildings.

Honda unveiled the prototypical E2-DR robot last week at the 2017 International Conference on Intelligent Robots and Systems in Vancouver, reports IEEE Spectrum. As the Honda video shows, the E2-DR robot can climb ladders, ascend stairs, crawl through tight spaces, and manipulate its body to squeeze through cracks.

Scientists have developed a novel weapon in the battle against deadly hospital-acquired infections — a textile that disinfects itself.

And independent tests show it can reduce bacteria levels by more than 90 per cent.

By incorporating the specially-engineered textile in a device designed to be used on hospital doors instead of the traditional aluminium door plate, that part of the door that people push to open it — they aim to bolster hygiene.
