Europe's very own dinosaurs -- the enigmatic Late Cretaceous rhabdodontids      (via sciencedaily.com)     Original source 

A new study brings together intriguing details about the little-known Rhabdodontidae dinosaurs of Late Cretaceous Europe. These gregarious herbivores, characterized by robust builds and beaks specialized for tough vegetation, inhabited the European archipelago. Despite being widespread and abundant, they vanished in Western Europe due to environmental changes around 69 million years ago, while surviving longer in Eastern Europe. Their fossil record offers valuable insights into their evolution and lifestyle, although its limited nature still challenges comprehensive understanding.

Three-eyed distant relative of insects and crustaceans reveals amazing detail of early animal evolution      (via sciencedaily.com)     Original source 

Scientists use cutting edge scanning technology to reconstruct 'fossil monster' that lived half a billion years ago. The creature's soft anatomy was well-preserved, allowing it to be imaged almost completely: It fills a gap in our understanding of the evolution of arthropods such as insects and crustaceans.

Direct power generation from methylcyclohexane using solid oxide fuel cells      (via sciencedaily.com)     Original source 

Methylcyclohexane is very promising as a hydrogen carrier that can safely and efficiently transport and store hydrogen. However, the dehydrogenation process using catalysts has issues due to its durability and large energy loss. Recently, researchers have succeeded in using solid oxide fuel cells to generate electricity directly from methylcyclohexane and recover toluene for reuse. This research is expected to not only reduce energy requirements but also explore new chemical synthesis by fuel cells.

Wastewater pipe dig reveals 'fossil treasure trove'      (via sciencedaily.com)     Original source 

A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark spine, and great white shark teeth have all been found in a mound of sand excavated from beneath Mangere Wastewater Treatment Plant in 2020.

Steam condenser coating could save 460M tons of CO2 annually      (via sciencedaily.com) 

If coal and natural gas power generation were 2% more efficient, then, every year, there could be 460 million fewer tons of carbon dioxide released and 2 trillion fewer gallons of water used. A recent innovation to the steam cycle used in fossil fuel power generation could achieve this.

Key role of ice age cycles in early human interbreeding      (via sciencedaily.com)     Original source 

Recent paleogenomic research revealed that interbreeding was common among early human species. However, little was known about when, where, and how often this hominin interbreeding took place. Using paleoanthropological evidence, genetic data, and supercomputer simulations of past climate, a team of international researchers has found that interglacial climates and corresponding shifts in vegetation created common habitats for Neanderthals and Denisovans, increasing their chances for interbreeding and gene flow in parts of Europe and central Asia.

Evolving elegance: Scientists connect beauty and safeguarding in ammonoid shells      (via sciencedaily.com)     Original source 

With 350 million years of evolution culminating in almost two centuries of scientific discourse, a new hypothesis emerges. Researchers propose a new explanation for why ammonoids evolved a highly elaborate, fractal-like geometry within their shells. Their analysis shows that the increasing complexity of shell structures provided a distinct advantage by offering improved protection against predators.

The oldest and fastest evolving moss in the world might not survive climate change      (via sciencedaily.com)     Original source 

A 390-million-year-old moss called Takakia lives in some of Earth's most remote places, including the icy cliffs of the Tibetan Plateau. In a decade-long project, a team of scientists climbed some of the tallest peaks in the world to find Takakia, sequence its DNA for the first time, and study how climate change is impacting the moss. Their results show that Takakia is one of the fastest evolving species ever studied -- but it likely isn't evolving fast enough to survive climate change.

Invasion of the Arctic Ocean by Atlantic plankton species reveals a seasonally ice-free ocean during the last interglacial      (via sciencedaily.com)     Original source 

A subpolar species associated with Atlantic water expanded far into the Arctic Ocean during the Last Interglacial, analysis of microfossil content of sediment cores reveals. This implies that summers in the Arctic were ice free during this period.

Bees evolved from ancient supercontinent, diversified faster than suspected      (via sciencedaily.com)     Original source 

The origin of bees is tens of millions of years older than most previous estimates, a new study shows. A team led by Washington State University researchers traced the bee genealogy back more than 120 million years to an ancient supercontinent, Gondwana, which included today's continents of Africa and South America.
