New research into the overlooked environmental impact of pet dogs has found far-reaching negative effects on wildlife, ecosystems and climate.

A new genomic study has uncovered long-lost genetic diversity in mammoth lineages spanning over a million years, providing new insights into the evolutionary history of these animals.

Could it be that one of only three known markers directly targeting the DNA does not exist outside the realm of microbes? Now, researchers have demonstrated that this marker -- N4-methylcytosine (4mC) -- is essential for sperm development and ...

Comprehensive reference genomes have now been assembled for six ape species: siamang (a Southeast Asian gibbon), Sumatran orangutan, Bornean orangutan, gorilla, bonobo and chimpanzee. Areas of their genomes previously inaccessible because of ...

Preparing catalysts by sending hot, steamy car exhaust over them could improve their efficiency and reduce the amount of rare and expensive metals required in vehicle catalytic converters and many other emission control and industrial processes.

A research team has developed an advanced delivery system that transports gene-editing tools based on the CRISPR/Cas9 gene-editing system into living cells with significantly greater efficiency than before. Their technology, ENVLPE, uses engineered . ...

About 66 million years ago, an asteroid slammed into the planet, wiping out all non-avian dinosaurs and about 70% of all marine species. But the crater it left behind in the Gulf of Mexico was a literal hotbed for life enriching the overlying ocean . ...

Researchers formally describe Helmetia expansa, offering new insights into its anatomy, behavior and evolutionary relationships.

Researchers report their discovery of fluorescent pigments in the feathers of Long-eared Owls, that can only be seen by humans with the help of ultraviolet light.

Japan's Ryukyu Islands, which includes Okinawa, are the exclusive home to two rare mammals, the Amami rabbit and Ryukyu long-furred rat. These animals are hard to observe, but conservationists wish to find out specific details about their diets. So . ...
