Published New tusk-analysis techniques reveal surging testosterone in male woolly mammoths



Traces of sex hormones extracted from a woolly mammoth's tusk provide the first direct evidence that adult males experienced musth, a testosterone-driven episode of heightened aggression against rival males, according to a new study.
Published Is the ocean a solution for ushering in the era of environmentally friendly energy?



Researchers confirm the superiority of seawater batteries that use chelating agents.
Published Brain circuits for locomotion evolved long before appendages and skeletons



Scientists found parallels between the neural circuitry that guides locomotion in sea slugs and in more complex animals like mammals.
Published Progress in alternative battery technology



It is not easy to make batteries cheap, efficient, durable, safe and environmentally friendly at the same time. Researchers have now succeeded in uniting all of these characteristics in zinc metal batteries.
Published Researchers design battery prototype with fiber-shaped cathode



In a new study, researchers made a cathode, or the positive end of a battery, in the shape of a thread-like fiber. The researchers were then able to use the fiber to create a zinc-ion battery prototype that could power a wrist watch.
Published Greener batteries



Our modern rechargeable batteries, such as lithium-ion batteries, are anything but sustainable. One alternative is organic batteries with redox-organic electrode materials (OEMs), which can be synthesized from natural 'green' materials. A team has now introduced a new OEM for aqueous organic high-capacity batteries that can be easily and cheaply recycled.
Published X-ray analysis sheds new light on prehistoric predator's last meal



We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of x-rays. Researchers used micro-CT scans to peer inside the fossilized stomach remains of a small marine reptile -- a plesiosaur nicknamed 'Eric' after a song from the comedy group Monty Python -- to determine what the creature ate in the lead up to its death.
Published Tiny biobattery with 100-year shelf life runs on bacteria



A tiny biobattery that could still work after 100 years has been developed.
Published Fossils reveal the long-term relationship between feathered dinosaurs and feather-feeding beetles



New fossils in amber have revealed that beetles fed on the feathers of dinosaurs about 105 million years ago, showing a symbiotic relationship of one-sided or mutual benefit.
Published New details of Tully monster revealed



For more than half a century, the Tully monster (Tullimonstrum gregarium), an enigmatic animal that lived about 300 million years ago, has confounded paleontologists, with its strange anatomy making it difficult to classify. Recently, a group of researchers proposed a hypothesis that Tullimonstrum was a vertebrate similar to cyclostomes (jawless fish like lamprey and hagfish). If it was, then the Tully monster would potentially fill a gap in the evolutionary history of early vertebrates. Studies so far have both supported and rejected this hypothesis. Now, using 3D imaging technology, a team in Japan believes it has found the answer after uncovering detailed characteristics of the Tully monster which strongly suggest that it was not a vertebrate. However, its exact classification and what type of invertebrate it was is still to be decided.
Published Electrification push will have enormous impacts on critical metals supply chain



The demand for battery-grade lithium, nickel, cobalt, manganese and platinum will climb steeply as vehicle electrification speeds up and nations work to reduce greenhouse gas emissions through mid-century. This surge in demand will also create a variety of economic and supply-chain problems, according to new research.
Published Solid-state lithium-sulfur batteries: Neutrons unveil sluggish charge transport



Solid-state Lithium-Sulfur batteries offer the potential for much higher energy densities and increased safety, compared to conventional lithium-ion batteries. However, the performance of solid-state batteries is currently lacking, with slow charging and discharging being one of the primary causes. Now, a new study shows that sluggish lithium ion transport within a composite cathode is the cause of this slow charging and discharging.
Published How were amino acids, one of the key building blocks of life, formed before the origin of life on Earth?



The amino acid abundances of two Ryugu particles were measured and compared with their rocky components. The results demonstrate the important role that water plays in the formation of amino acids on the giant precursors of asteroids like Ryugu. Our solar system formed from a molecular cloud, which was composed of gas and dust that was emitted into the interstellar medium (ISM), a vast space between stars. On collapse of the molecular cloud, the early sun was formed, with a large disk of gas and dust orbiting it. The dusty material collided to produce rocky material that would eventually grow in size to give large bodies called planetesimals.
Published Major storage capacity in water-based batteries



Chemical engineers have discovered a 1,000% difference in the storage capacity of metal-free, water-based battery electrodes.
Published One of Swedish warship Vasa's crew was a woman


When the human remains found on board the Swedish warship Vasa (1628) were investigated, it was determined that the skeleton designated G was a man. New research now shows that the skeleton is actually from a woman. About thirty people died when Vasa sank on its maiden voyage in Stockholm, 1628. We cannot know who most of them were, only one person is named in the written sources. When the ship was raised in 1961 it was the scene of a comprehensive archaeological excavation, in which numerous human bones were found on board and examined.
Published Yak milk consumption among Mongol Empire elites


For the first time, researchers have pinpointed a date when elite Mongol Empire people were drinking yak milk, according to a new study.
Published Researchers use 21st century methods to record 2,000 years of ancient graffiti in Egypt


Researchers are learning more about ancient graffiti -- and their intriguing comparisons to modern graffiti -- as they produce a state-of-the-art 3D recording of the Temple of Isis in Philae, Egypt.
Published Predatory dinosaurs such as T. rex sported lizard-like lips


A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths.
Published Ancient giant amphibians swam like crocodiles 250 million years ago


Ancient 2m-long amphibians swam like crocodiles long before true crocodiles existed, according to a new study.
Published Revolutionary battery technology to boost EV range 10-fold or more


A team develops layering-charged, polymer-based stable high-capacity anode material.
