What the inner ear of Europasaurus reveals about its life      (via sciencedaily.com) 

Europasaurus is a long-necked, herbivorous dinosaur that lived in the Late Jurassic, about 154 million years ago, on a small island in modern-day Germany. Recently, scientists examined fossil braincase material of Europasaurus with the aid of micro-computed tomography (micro-CT). The digital reconstruction of the inner ear of Europasaurus gave the researchers new insights not only into its hearing ability, but also into its reproductive and social behavior.

Early forests did not significantly change the atmospheric CO2      (via sciencedaily.com)     Original source 

Scientists have discovered that the atmosphere contained far less CO2 than previously thought when forests emerged on our planet, the new study has important implications for understanding how land plants affect the climate.

Fossil CSI: Giant extinct marine reptile graveyard was likely ancient birthing grounds      (via sciencedaily.com) 

An international research team examines a rich fossil bed in the renowned Berlin-Ichthyosaur State Park in Nevada's Humboldt-Toiyabe National Forest, where many 50-foot-long ichthyosaurs (Shonisaurus popularis) lay petrified in stone. The study offers a plausible explanation as to how at least 37 of these marine reptiles came to meet their ends in the same locality -- a question that has vexed paleontologists for more than half a century. The research presents evidence that these ichthyosaurs died at the site in large numbers because they were migrating to this area to give birth for many generations across hundreds of thousands of years.

Linking fossil climate proxies to living bacteria helps climate predictions      (via sciencedaily.com) 

Fossilized microbial skins can give us a glimpse of how the climate was in the deep geological past. By discovering the 'missing link' between such fossil skins and the skins of living bacteria, researchers have greatly improved the accuracy of climate reconstructions and predictions.

A shield for 2D materials that adds vibrations to reduce vibration problems      (via sciencedaily.com) 

A new study demonstrates a new, counterintuitive way to protect atomically-thin electronics -- adding vibrations, to reduce vibrations. By squeezing a liquid-metal gallium droplet, graphene devices are painted with a protective coating of gallium-oxide that can cover millimeter-wide scales, making it potentially applicable for industrial large-scale fabrication. The new technique improves device performance as well as protecting 2D materials from thermal vibration in neighboring materials.

Mitigating corrosion by liquid tin could lead to better cooling in fusion reactors      (via sciencedaily.com) 

Researchers have clarified the chemical compatibility between high temperature liquid metal tin (Sn) and reduced activation ferritic martensitic, a candidate structural material for fusion reactors. This discovery has paved the way for the development of a liquid metal tin divertor, which is an advanced heat-removal component of fusion reactors. A device called a divertor is installed in the fusion reactors to maintain the purity of the plasma. For divertors, there has been demand for liquid metals that can withstand extremely large heat loads from high-temperature plasma.

Chaos gives the quantum world a temperature      (via sciencedaily.com) 

Two seemingly different areas of physics are related in subtle ways: Quantum theory and thermodynamics. How can the laws of thermodynamics arise from the laws of quantum physics? This question has now been pursued with computer simulations, which showed that chaos plays a crucial role: Only where chaos prevails do the well-known rules of thermodynamics follow from quantum physics.

Fossil site reveals giant arthropods dominated the seas 470 million years ago      (via sciencedaily.com) 

Discoveries at a major new fossil site in Morocco suggest giant arthropods -- relatives of modern creatures including shrimps, insects and spiders -- dominated the seas 470 million years ago.

True giant wombat gives Diprotodon podium a wobble      (via sciencedaily.com) 

While the Diprotodon -- the extinct megafauna species that is distantly related to wombats but was the size of a small car -- is commonly (but incorrectly) thought of as Australia's 'giant wombat', researchers have shed light on a large species that does belong in the modern-day wombat family. The complete skull of this true fossil giant wombat, found in a Rockhampton cave in Queensland, Australia and estimated to be around 80,000 years old, has been described for the first time.

Gold-based passive heating for eyewear      (via sciencedaily.com) 

Researchers have developed a new transparent gold nanocoating that harnesses sunlight to heat the lenses of glasses, thereby preventing them from fogging in humid conditions. This coating could potentially also be applied to car windshields.

Immune system of modern Papuans shaped by DNA from ancient Denisovans, study finds      (via sciencedaily.com) 

Modern Papuans' immune system likely evolved with a little help from the Denisovans, a mysterious human ancestor who interbred with ancient humans, according to a new study.

Smilodon's sabre teeth      (via sciencedaily.com)     Original source 

Researchers have tested the biting efficiency of Smilodon, an extinct species of carnivore close to the extant felines. Using high-precision 3D scans and simulation methods, the team has just revealed how these animals managed to bite despite the impressive length of their teeth.

Discovery of world's oldest DNA breaks record by one million years      (via sciencedaily.com) 

Two-million-year-old DNA has been identified -- opening a 'game-changing' new chapter in the history of evolution. Microscopic fragments of environmental DNA were found in Ice Age sediment in northern Greenland. Using cutting-edge technology, researchers discovered the fragments are one million years older than the previous record for DNA sampled from a Siberian mammoth bone. The ancient DNA has been used to map a two-million-year-old ecosystem which weathered extreme climate change.

New branch on tree of life includes 'lions of the microbial world'      (via sciencedaily.com)     Original source 

There's a new branch on the tree of life and it's made up of predators that nibble their prey to death. These microbial predators fall into two groups, one of which researchers have dubbed 'nibblerids' because they, well, nibble chunks off their prey using tooth-like structures. The other group, nebulids, eat their prey whole. And both comprise a new ancient branch on the tree of life called 'Provora,' according to a new article.

Ancient amphibians had their bones cooked      (via sciencedaily.com) 

Scientists have solved a decades-long mystery as to why ancient tetrapods -- amphibian-like creatures that lived over 300 million years ago -- preserved in one of Ireland's most important fossil sites seemingly had their bones cooked after they died.

Jawbone may represent earliest presence of humans in Europe      (via sciencedaily.com) 

For over a century, one of the earliest human fossils ever discovered in Spain has been long considered a Neanderthal. However, new analysis from an international research team dismantles this century-long interpretation, demonstrating that this fossil is not a Neanderthal; rather, it may actually represent the earliest presence of Homo sapiens ever documented in Europe.
