Scientists have demonstrated that fish think 'it's me' when they see themselves in a picture. The researchers found that the determining factor was not the fish seeing their own body but seeing their face.

Scientists have compared the relationship among the strength of flight bones, body mass, and the way modern birds fly to better understand the evolution of flight in birds and extinct animals, such as the Pteranodon.

A new study found that nectar-feeding bats evolved extra-long whiskers unlike those of any other bat species that allow them to hover as they feed on flowers, much like hummingbirds. The researchers used high-speed cameras to capture how the forward-facing whiskers provide enhanced spatial information for fast, precise flight maneuvers.

Caribou have been using the same Arctic calving grounds for more than 3,000 years. Female caribou shed their antlers within days of giving birth, leaving behind a record of their annual travels across Alaska and Canada's Yukon that persists on the cold tundra for hundreds or even thousands of years. Researchers recovered antlers that have sat undisturbed on the arctic tundra since the Bronze Age.

New Zealand is one of only a few island nations that could continue to produce enough food to feed its population in a nuclear winter, researchers have found.

Can a pigeon match wits with artificial intelligence? Researchers tested pigeons' learning abilities and concluded the birds employ the same basic process, called associative learning, as the most advanced AI technologies.

Researchers discovered a new species of frog in Africa that has an unusual trait: it's completely silent. The Ukaguru spiny-throated reed frog does not croak, sing or ribbit. Found in Tanzania's Ukaguru Mountains for which it is named, Hyperolius ukaguruensis is among the few frogs around the world that do not vocalize to other frogs.

Researchers show that brain organoids -- clumps of lab-grown neurons -- can integrate with rat brains and respond to visual stimulation like flashing lights.

The CT-scanned skull of a 319-million-year-old fossilized fish, pulled from a coal mine in England more than a century ago, has revealed the oldest example of a well-preserved vertebrate brain.

By working together, dolphins and net-casting fishers in Brazil each catch more fish, a rare example of an interaction by two top predators that is beneficial to both parties, researchers have concluded following 15 years of study of the practice.

A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.

A new study has uncovered a new thalattosuchian -- an ancient 'sister' of modern-day crocodiles' ancestors.

The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?

Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein.

What drives crocodile evolution? Is climate a major factor or changes in sea levels? Determined to find answers to these questions, researchers discovered that while changing temperatures and rainfall had little impact on the crocodiles' gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.

Humans retain an understanding of gestures made by other great apes, even though we no longer use them ourselves, according to a new study.

A researcher has created a computer reconstruction of a virus, including its complete native genome. Although other researchers have created similar reconstructions, this is believed to be the first to replicate the exact chemical and 3D structure of a 'live' virus.

Varroa destructor is an ectoparasitic mite that can cause European honey bee colonies to collapse by spreading Deformed wing virus as they feed. A study suggests a relatively small number of mites can contribute to a large number of infected bees.

The discovery of more than 250 fossilized eggs reveals intimate details about the lives of titanosaurs in the Indian subcontinent, according to a new study.

Crocodiles were mummified in a unique way at the Egyptian site of Qubbat al-Hawa during the 5th Century BC, according to a new study.
