MXenes for energy storage      (via sciencedaily.com)     Original source 

A new method in spectromicroscopy significantly improves the study of chemical reactions at the nanoscale, both on surfaces and inside layered materials. Scanning X-ray microscopy (SXM) at MAXYMUS beamline of BESSY II enables the investigation of chemical species adsorbed on the top layer (surface) or intercalated within the MXene electrode (bulk) with high chemical sensitivity.

Ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere      (via sciencedaily.com)     Original source 

An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere.

Early Homo sapiens facilitated the establishment of the Bonelli's eagle in the Mediterranean 50,000 years ago      (via sciencedaily.com)     Original source 

Scientists have unraveled the ancestral history of one of the most iconic birds of prey in the current Iberian fauna: the Bonelli's eagle (Aquila fasciata). The study combines evidence from several disciplines, including palaeontology, genetics and ecology, to answer questions about when and why the Bonelli's eagle, a species primarily found in tropical and subtropical areas, colonized the Mediterranean Basin.

Sharks have depleted functional diversity compared to the last 66 million years      (via sciencedaily.com)     Original source 

New research has found that sharks retained high levels of functional diversity for most of the last 66 million years, before steadily declining over the last 10 million years to its lowest value in the present day.

Ancient ocean slowdown warns of future climate chaos      (via sciencedaily.com)     Original source 

When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A new study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline.

No bones about it: 100-million-year-old bones reveal new species of pterosaur      (via sciencedaily.com)     Original source 

New research has identified 100-million-year-old fossilized bones discovered in western Queensland as belonging to a newly identified species of pterosaur, which was a formidable flying reptile that lived among the dinosaurs.

Looking for a new battery platform? Focus on the essentials      (via sciencedaily.com)     Original source 

In facing life's many challenges, we often opt for complex approaches to finding solutions. Yet, upon closer examination, the answers are often simpler than we expect, rooted in the core "essence" of the issue. This approach was demonstrated by a research team in their publication on addressing the inherent issues of solid-state batteries.

Electrified charcoal 'sponge' can soak up CO2 directly from the air      (via sciencedaily.com)     Original source 

Researchers have developed a low-cost, energy-efficient method for making materials that can capture carbon dioxide directly from the air. Researchers used a method similar to charging a battery to instead charge activated charcoal, which is often used in household water filters.

Gigantic Jurassic pterosaur fossil unearthed in Oxfordshire, UK      (via sciencedaily.com)     Original source 

A team of palaeontologists has discovered a fossil of a gigantic flying reptile from the Jurassic period with an estimated wingspan of more than three metres -- making it one of the largest pterosaurs ever found from that era.

An unlikely hero in evolution: Worms      (via sciencedaily.com)     Original source 

One of Earth's most consequential bursts of biodiversity -- a 30-million-year period of explosive evolutionary changes spawning innumerable new species -- may have the most modest of creatures to thank for the vital stage in life's history: worms.

'Ugly' fossil places extinct saber-toothed cat on Texas coast      (via sciencedaily.com)     Original source 

This fossil looks like a lumpy, rounded rock with a couple of exposed teeth that are a little worse for wear, having been submerged and tumbled along the floor of the Gulf of Mexico for thousands of years before washing up on a beach. But when it was X-rayed a doctoral student saw there was more to the fossil that met the eye: a hidden canine tooth that had not yet erupted from the jaw bone. It was just what researchers needed to identify the fossil as belonging to a Homotherium, a genus of large cat that roamed much of the Earth for millions of years.
