A reconstruction of prehistoric temperatures for some of the oldest archaeological sites in North America      (via sciencedaily.com) 

Scientists often look to the past for clues about how Earth's landscapes might shift under a changing climate, and for insight into the migrations of human communities through time. A new study offers both by providing, for the first time, a reconstruction of prehistoric temperatures for some of the first known North American settlements.

Highly charged ions melt nano gold nuggets      (via sciencedaily.com)     Original source 

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.

Probe where the protons go to develop better fuel cells      (via sciencedaily.com)     Original source 

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.

Batteries: Passivation layer mystery solved      (via sciencedaily.com) 

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.

'Fishing' for biomarkers      (via sciencedaily.com) 

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.

Genome research: Origin and evolution of vine      (via sciencedaily.com) 

Cultivation and growth of grapevines have strongly influenced European civilizations, but where the grapevine comes from and how it has spread across the globe has been highly disputed so far. In an extensive genome project, researchers have determined its origin and evolution from the wild vine to today's cultivar by analyzing thousands of vine genomes collected along the Silk Road from China to Western Europe.
