Beryllium-10, a rare radioactive isotope produced by cosmic rays in the atmosphere, provides valuable insights into the Earth's geological history. A research team has discovered an unexpected accumulation of this isotope in samples taken from the Pacific seabed. Such an anomaly may be attributed to shifts in ocean currents or astrophysical events that occurred approximately 10 million years ago. The findings hold the potential to serve as a global time marker, representing a promising advancement in the dating of geological archives spanning millions of years.

Researchers have analyzed the soft tissue from a fossilized plesiosaur for the first time. The results show that the long-necked marine reptile had both smooth and scaly skin. This was likely so it could both swim rapidly and move along rough seabeds.

The sounds that make up humpback whale songs follow some of the same statistical rules seen in human languages, which may be because of how they are learned

Genetic analysis suggests a form of mosquito found in urban subway systems evolved in the Middle East thousands of years ago

A remarkable plesiosaur fossil reveals that the extinct reptiles had scales like modern sea turtles, unlike the ichthyosaurs that lived during the same period

A group of male koalas were filmed grooming and playing together, in contrast to their solitary reputation, probably as a result of an unusually dense population in southern Victoria

Sixty-six million years ago, at the end of the Cretaceous Period, an asteroid impact near the Yucat n Peninsula of Mexico triggered the extinction of all known non-bird dinosaurs. But for the early ancestors of today's waterfowl, surviving that mass extinction event was like ... water off a duck's back. Location matters, as Antarctica may have served as a refuge, protected by its distance from the turmoil taking place elsewhere on the planet. Fossil evidence suggests a temperate climate with lush vegetation, possibly serving as an incubator for the earliest members of the group that now includes ducks and geese.

Where lies the origin of the Indo-European language family? Researchers contribute a new piece to this puzzle. They analyzed ancient DNA from 435 individuals from archaeological sites across Eurasia between 6.400--2.000 BCE. They found out that a newly recognized Caucasus-Lower Volga population can be connected to all Indo-European-speaking populations.

A newly analysed fossil skull settles a palaeontological debate over Vegavis iaai, confirming it as a relative of ducks and geese that lived 69 million years ago

When spiders self-amputate two of their legs, they quickly adjust their running gait so they can return to full speed

Recognising that someone lacks information you possess is key for effective communication and cooperation, and bonobos seem to share this skill with humans

From narcos to navigating FARC paramilitaries, Angela Maldonado has been spearheading a campaign to protect the Amazon's night monkeys from an illegal wildlife trade

Wandering salamanders pump their toes full of blood before lifting their feet, a trick that may help them release their sticky grip while conserving energy

Male dolphins have been observed shooting jets of urine into the air and other dolphins seem to follow the stream, perhaps to pick up social cues

Sharks and rays have populated the world's oceans for around 450 million years, but more than a third of the species living today are severely threatened by overfishing and the loss of their habitat. Palaeobiologists have now investigated whether and how global warming influences the diversity of sharks based on climate fluctuations between 200 and 66 million years ago. According to the study, higher temperatures and more shallow water areas have a positive effect, while higher CO2 levels have a clearly negative effect.

Indigenous peoples of the Arctic traditionally use polar bear fur for its ice-resistant properties, but the science behind the bears’ natural antifreeze hasn't been studied until now

A provocative new book delves into the way humans – and elephants – evolved to manage risk. We might do better to think more like elephants
