In our daily lives, lithium-ion batteries have become indispensable. They function only because of a passivation layer that forms during their initial cycle. As researchers found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution. Their findings allow the optimization of the performance and lifetime of future batteries.

A new study investigates how an extinct, carnivorous marsupial relative with canines so large they extended across the top of its skull could hunt effectively despite having wide-set eyes, like a cow or a horse. The skulls of carnivores typically have forward-facing eye sockets, or orbits, which helps enable stereoscopic (3D) vision, a useful adaptation for judging the position of prey before pouncing. Scientists studied whether the 'marsupial sabertooth' Thylacosmilus atrox could see in 3D at all.

Researchers have devised a tiny, nano-sized sensor capable of detecting protein biomarkers in a sample at single-molecule precision. Fittingly coined as 'hook and bait,' a tiny protein binder fuses to a small hole created in the membrane of a cell -- known as a nanopore ­-- which allows ionic solution to flow through it. When the sensor recognizes a targeted molecule, the ionic flow changes. This change in flow serves as the signal from the sensor that the biomarker has been found.

When lymphatic vessels fail, typically their ability to pump out the fluid is compromised. Researchers have now developed a new treatment using nanoparticles that can repair lymphatic vessel pumping. Traditionally, researchers in the field have tried to regrow lymphatic vessels, but repairing the pumping action is a unique approach.

Leading edge technology has uncovered secrets about a world-renowned fossil hoard that could offer vital clues about early life on Earth. Researchers who analyzed the 400 million-year-old cache, found in rural north-east Scotland, say their findings reveal better preservation of the fossils at a molecular level than was previously anticipated.

Scientists have transformed single-cell algae into functional perovskite materials. The team has converted mineral shells of algae into lead halide perovskites with tunable physical properties. The new perovskites have unique nano-architectures unachievable by conventional synthetic production. The method can be applied to the mass production of perovskites with tunable structural and electro-optical properties from single-celled organisms.

A 'best practice' protocol for researchers developing piezoelectric materials has been developed by scientists. The protocol was developed by an international team led by physicists in response to findings that experimental reports lack consistency. The researchers made the shocking discovery that nine out of 10 scientific papers miss experimental information that is crucial to ensure the reproducibility of the reported work.

Researchers have developed and demonstrated an efficient and scalable technique that allows them to manufacture soft polymer materials in a dozen different structures, or 'morphologies,' from ribbons and nanoscale sheets to rods and branched particles. The technique allows users to finely tune the morphology of the materials at the micro- and nano-scale.
