Scientists have demonstrated a new system that can restore crucial molecular and cellular functions in pigs one hour after death. The experiments could help widen the organ transplantation pool and may even lead to new treatments for heart attacks.

Scientists studying memory and learning in frog-eating bats have made a surprising discovery, demonstrating that they can recognize ringtones tied to food rewards up to four years later, which is believed to help them hunt in the wild.

A new study has shed light on why elephants, one of the biggest animals on the planet, paradoxically experience unusually low rates of cancer. The research found these remarkable mammals carry unique genetic variants that reduce their risk of tumors.

Researchers have announced success from a pair of experimental pig-to-human heart transplant procedures completed on recently deceased human subjects who were kept on mechanical ventilation for three days while the organs were monitored in their bodies.

Presented by the California Academy of Sciences, the BigPicture Competition annually delivers an incredible collection of nature photographs. This year’s shots span from a bizarre cactus bee mating ritual to a surreal glimpse at a sea star spawning.

A new article has offered insights into the world’s first pig-to-human heart transplant, which took place earlier this year. Researchers report the patient died unexpectedly two months after the procedure and the exact cause of death is still unclear.

Dinosaurs sit at the crossroads between reptiles and birds, leading scientists to debate whether they were warm- or cold-blooded. A new study may have the answer for different dinosaurs by analyzing metabolic markers from their breath in their bones.

Ordinarily, when studying the behavior of animals, scientists have to watch many hours of video footage of the creatures going about their daily lives. That may soon no longer be necessary, however, thanks to a new critter-watching computer system.

What happens when you spray a big territorial carnivore in the face with the hormone oxytocin? Researchers working in a South African wildlife reserve have been experimenting with the effects of oxytocin on lions in an attempt to answer that question.

In its second year, the World Nature Photography Awards presents a dazzling array of wildlife from across the globe, including a humpback whale in front of the New York City skyline, an orangutan striking a pose, and a glimpse at ants working together.

A team of researchers has reported the development of an algorithm that can translate the emotional state of pigs from the sound of their grunts. The researchers indicate the system could be used to monitor the well-being of pigs on a farm in real-time.

Two new studies collected air samples from zoos and demonstrated the ability to identify a range of animals living there from their airborne DNA. This could eventually be used as a non-invasive way to track biodiversity.
