Living alligators expose why juvenile fossils can fool classification methods

A new approach for paleontologists when identifying vertebrae fossils?

Fossil finds are exciting moments that sometimes introduce the world to an ancient mammal or dinosaur that existed millions of years ago. But a longstanding problem in paleontology is that fossils are often incomplete, and subtle differences between certain species, along with major changes that can occur as an animal grows, complicate species identification. A paper published this month in Paleobiology lays the groundwork for a new approach to correctly identifying ancient animal fossils, with significant implications for vertebrate paleontology.

Unhoused people and wildlife are increasingly coming into contact. Here's what can be done to protect them

As homelessness increases around the world, more unhoused people are turning to parks and other urban green spaces to seek shelter. However, these places are also home to animals that live in and around urban areas.

Asteroid with unexplained orbital shift turns out to be a 'dark comet'

Typically, astronomers identify comets by their distinct atmospheres, or comae, and their tails, which are created as the sun vaporizes a comet's ice. These features emit a glow when sunlight bounces off dust and water droplets. As gas escapes the body of the comet, it also acts as a tiny thruster, subtly changing the comet's path.

Quantum materials could transform technologies ranging from powerful computers and ultrasecure communications to advanced energy systems. But there has always been one major obstacle.

Naked mole-rat queens produce an odorous chemical that ensures that only they can reproduce

An international team led by Dr. Gary Lewin, group leader of the Molecular Physiology of Somatosensory Perception lab at the Max Delbrück Center in Berlin, has discovered that the queens of naked mole-rat colonies release a volatile compound called isopropyl myristate, which induces temporary infertility in all other females in the colony.

Desert dust in Europe is increasing with implications for health and solar energy installations

While particulate matter air pollution from human activity in transportation, households and industry is decreasing in Europe, thanks to strict regulations, another source is developing in the opposite direction: desert dust.

New study pinpoints Europe's most critical wetlands for climate action

Wetlands have shaped human life in Europe since ancient times. These ecosystems provided essential resources and safe havens for plants and animals, and in many regions they also held spiritual and ritual significance. For millennia, wetlands covered vast parts of the European continent.

We’re finally learning what happens to gifted children in adulthood | New Scientist

Gifted children are exceptionally talented or intelligent for their age

Lady Gaga may seem to have little in common with Mark Zuckerberg and Sergey Brin, other than being extremely successful. But there is a connection: all three were deemed gifted in childhood.

Healthier, more sustainable diets could reshape global agriculture: New study shows by how much

There is a clear need to shift toward healthier and more sustainable food systems. According to the 2025 EAT-Lancet Commission Report, global adoption of a flexitarian Planetary Health Diet could prevent around 15 million premature adult deaths per year.

The effects of extreme space weather may be larger than previously thought, research in the journal Nature reveals. The paper, titled "Regression to the mean can explain saturation of geomagnetic storms," is led by Dr. Nithin Sivadas of NASA's Goddard Space Flight Center and co-authored by Dr. Maria Walach from Lancaster University.
