Scientists discover 'zoned development' in dinosaur skin, with zones of reptile-style scales and zones of bird-like skin with feathers. A new dinosaur skin fossil has been found to be composed of silica -- the same as glass.

A recent boom in the purple sea urchin population off the southern Oregon Coast appears to have had an indirect and negative impact on the gray whales that usually forage in the region, a new study shows.

The study's findings show mergansers arrived in the New Zealand region at least seven million years ago from the Northern Hemisphere, in a separate colonisation event to that which led to the Brazilian merganser.

Using citizen science, photographs, on-water observations and the combination of morphological and genetic data, researchers have provided evidence that the Atlantic cownose ray has recently made a new home in Bermuda. Results show that after hundreds of years of natural history records, this is a novel migration of Atlantic cownose rays to Bermuda.

Large language model-based chatbots can't effectively recognize users' motivation when they are hesitant about making healthy behavior changes, but they can support those who are committed to take action, say researchers.

The treatment of animals rates higher than green issues when consumers choose meat and dairy products. That's according to a new study, which suggests that while consumers consider sustainability important, other factors such as taste, quality, and animal welfare take precedence in their purchasing decisions.

Strongly interacting systems play an important role in quantum physics and quantum chemistry. Stochastic methods such as Monte Carlo simulations are a proven method for investigating such systems. However, these methods reach their limits when so-called sign oscillations occur. This problem has now been solved using the new method of wavefunction matching.

In the emperor penguin courtship call, male vocalizations are composed of long, slow bursts with lower frequency tones than the female version. But calls of SeaWorld San Diego male penguin E-79 defied this binary. Also unusual was this penguin's male companion, E-81. The pair 'kept company' and sometimes exhibited ritual courtship displays. Researchers studied the courtship calls of E-79 and E-81, recording the birds in their below-freezing enclosure and refining the usual technique for analyzing the bursts.

When tiger beetles hear a bat nearby, they respond by creating a high-pitched, ultrasonic noise, and for the past 30 years, no one has known why. In a new study, scientists lay the mystery to rest by showing that tiger beetles use ultrasonic warning signals that mimic those of toxic moths.

A parasitic worm that can infest the brains of moose appears to be playing a role in the decline of the iconic animal in some regions of North America. Moose populations have been dwindling for years across the country due to many contributing factors, but new research has found the impact of Eleaophora schneideri, also known as the arterial worm, has likely been underestimated.

What makes the oldfield mouse steadfastly monogamous throughout its life while its closest rodent relatives are promiscuous? The answer may be a previously unknown hormone-generating cell. Scientists discover the cells and hormones that inspire mice to nurture their young; the same hormones are also present in humans.
