Piecing together the crushed skull of a fossil bird that lived alongside the dinosaurs helped researchers extrapolate what its brain would have looked like: big olfactory bulbs would have meant that this bird, the earliest known animal to eat fruit, had a better sense of smell than most modern birds. And the bones around its eye sockets revealed that it would have been better at seeing by day than at night.

The metal-carbon dioxide battery is a promising and environmentally friendly technology, but its energy efficiency is limited. Recently, a research team has discovered an innovative way to overcome this problem by introducing an unconventional phase nanomaterial as a catalyst, boosting battery energy efficiency up to 83.8%. The study reveals a novel design of catalysts for the new generation of meta-gas batteries that can contribute to carbon neutral goals.

Today, increasing levels of carbon dioxide in the atmosphere are warming up the planet. Climate change can disrupt the balance of ecosystems and contribute to endangerment and extinction of some species. New research suggests that a period of intense volcanism in the Central Andes may be the missing link in the story of past climate changes that led to the extinctions of ancient marine mammals.

A giant kangaroo that once roamed on four legs through remote forests in the Papua New Guinea Highlands may have survived as recently as 20,000 years ago -- long after large-bodied megafauna on mainland Australia went extinct, new research indicates. Palaeontologists, archaeologists and geoscientists, have used new techniques to re-examine megafauna bones from the rich Nombe Rock Shelter fossil site in Chimbu Province in a bid to better understand the intriguing natural history of PNG.

An international team has reconstructed the genome organization of the earliest common ancestor of all mammals. The reconstructed ancestral genome could help in understanding the evolution of mammals and in conservation of modern animals. The earliest mammal ancestor likely looked like the fossil animal 'Morganucodon' which lived about 200 million years ago.

Researchers offer a new mixture of metallic elements to serve as lithium-ion cathodes. This 'high-entropy doping strategy' is part of an effort to remove cobalt -- and expensive and geopolitically problematic mineral -- from LI batteries.

1 in 5 adult female white-necked jacobin hummingbirds look like males. New research shows that this is a rare case of 'deceptive mimicry' within a species: Females with male-like plumage are trying to pass themselves off as males, and as a result receive a benefit in the form of reduced aggression from males.

The issue of battery usage inefficiency in electric vehicles resulting from an inaccurate battery charge measurement may finally get resolved, thanks to a diamond quantum sensor prototype. The sensor can measure currents in a wide range as well as detect milliampere-level currents in a noisy environment, improving the detection accuracy from 10% to within 1%.

Did the first ancestors of whales pick up where the mosasaurs left off 66 million years ago, after the extinction of all the large predatory marine reptiles? A study has looked into the possible convergences in morphology and behavior that may exist between these two groups of large marine predatory animals.

Accelerating demand for renewable energy and electric vehicles is sparking a high demand for the batteries that store generated energy and power engines. But the batteries behind these sustainability solutions aren't always sustainable themselves. Scientists have now create a zinc battery with a biodegradable electrolyte from an unexpected source -- crab shells.
