Published Research into birds killed in window collisions reveals their microbiomes


Researchers collected the bodies of birds that crashed into buildings while migrating, and used these specimens to learn about the relationship between birds and the microbes living in their guts -- which appears to be wildly different from mammals and their microbiomes.
Published Highly charged ions melt nano gold nuggets



Shooting ions is very different from shooting a gun: By firing highly charged ions onto tiny gold structures, these structures can be modified in technologically interesting ways. Surprisingly, the key is not the force of impact, but the electric charge of the projectiles.
Published Biomolecules: Trying nanometer measurement for size



As part of a comparative international study, researchers have successfully tested and validated a method of investigating dynamic protein structures.
Published Probe where the protons go to develop better fuel cells



Researchers have uncovered the chemical inner-workings of an electrolyte they developed for a new generation of solid oxide fuel cells. To uncover the location of the proton-introduction reaction, the team studied extensively the hydration reaction of their scandium-substituted barium zirconate perovskite through a combination of synchrotron radiation analysis, large-scale simulations, machine learning, and thermogravimetric analysis. The new data has the potential to accelerate the development of more efficient fuel cells.
Published What should we call evolution driven by genetic engineering? Genetic welding, says researcher


With CRISPR-Cas9 technology, humans can now rapidly change the evolutionary course of animals or plants by inserting genes that can easily spread through entire populations. An evolutionary geneticist proposes that we call this evolutionary meddling 'genetic welding.' He argues that we must scientifically and ethically scrutinize the potential consequences of genetic welding before we put it into practice.
Published Nanophysics: The right twist


Stacked layers of ultrathin semiconductor materials feature phenomena that can be exploited for novel applications. Physicists have studied effects that emerge by giving two layers a slight twist.
Published Deceptive daisy's ability to create fake flies explained


Researchers have discovered how a South African daisy makes fake lady flies on its petals to trick male flies into pollinating it.
Published Semiconductor lattice marries electrons and magnetic moments


A model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.
Published Researchers get to the 'bottom' of how beetles use their butts to stay hydrated


Beetles are champions at surviving in extremely dry environments. In part, this property is due to their ability to suck water from the air with their rear ends. A new study explains just how. Beyond helping to explain how beetles thrive in environments where few other animals can survive, the knowledge could eventually be used for more targeted and delicate control of global pests such as the grain weevil and red flour beetle.
Published Ultra-lightweight multifunctional space skin created to withstand extreme conditions in space


A new nano-barrier coating could help protect ultra-lightweight carbon composite materials from extreme conditions in space, according to a new study.
Published Batteries: Passivation layer mystery solved


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.
Published 'Inkable' nanomaterial promises big benefits for bendable electronics


An international team of scientists is developing an inkable nanomaterial that they say could one day become a spray-on electronic component for ultra-thin, lightweight and bendable displays and devices.
Published 'Fishing' for biomarkers


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.
Published Nanotechnology could treat lymphedema


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.
Published Mind-control robots a reality?


Researchers have developed biosensor technology that will allow you to operate devices, such as robots and machines, solely through thought control.
Published 'Talking' concrete could help prevent traffic jams and cut carbon emissions


An increasing number of U.S. interstates are set to try out an invention that could save millions of taxpayer dollars and significantly reduce traffic delays. The invention, a sensor that allows concrete to 'talk,' decreases construction time and how often concrete pavement needs repairs while also improving the road’s sustainability and cutting its carbon footprint. Embedded directly into a concrete pour, the sensor sends engineers more precise and consistent data about the concrete’s strength and need for repair than is possible with currently used tools and methods.
Published Major advance in super-resolution fluorescence microscopy


Pushing the MINFLUX technique to higher spatial and temporal precision allows protein dynamics to be observed under physiological conditions.
Published Researchers control the degree of twist in nanostructured particles


Micron-sized 'bow ties,' self-assembled from nanoparticles, form a variety of different curling shapes that can be precisely controlled, a research team has shown.
Published Neolithic ceramics reveal dairy processing from milk of multiple species


A new study has found evidence of cheesemaking, using milk from multiple animals in Late Neolithic Poland.
Published Humans are leaving behind a 'frozen signature' of microbes on Mount Everest


Thanks to technological advances in microbial DNA analysis, researchers have discovered that mountaineers' boots aren't the only things leaving footprints on the world's tallest mountain. When someone sneezes on Everest, their germs can last for centuries.
