Researchers have developed a way to treat male infertility by delivering nanoparticles loaded with proteins directly into the testes. In tests in mice, previously infertile animals were soon able to father pups at a similar rate as unaffected mice.

If the movie Jurassic World is to be believed, pterosaurs could easily catch human-sized prey. A newly discovered species of the prehistoric reptile wouldn't have posed much of a threat to us, however, as it likely fed more like a modern sandpiper.

The tardigrade is one of nature’s toughest creatures. Now scientists have discovered a new species that adds to an already impressive array of survival tools by employing a type of fluorescent shield to protect itself against lethal UV radiation.

Some are born with three arteries in their forearm, and a new study is suggesting more and more people are holding onto this temporary embryonic artery into adulthood, which the researchers believe could be natural selection at work.

The mosasaur was likely one of the most ferocious prehistoric marine predators. A previously unknown species of the reptile has now been classified, and it sported a crocodile-like snout that may have allowed it to catch prey that others missed.

A persistent scientific mystery over the past century has been exactly how some animals seemingly have the ability to sense the Earth’s magnetic field. A team of researchers are suggesting the magnetic-sensing bacteria could be symbiotically generating this novel sense.

After only 162 years, the first complete dinosaur skeleton to be recovered has finally been properly reconstructed and studied. The 193-million-year-old remains of a Scelidosaurus spent over 150 years stored at the Natural History Museum in London.

A new experiment placing bacteria on the outside of the International Space Station (ISS) has found that micro-organisms can survive in space for years, or even decades. The study lends weight to the idea that life could travel between planets.

A new genomic study has homed in on exactly when and where modern penguins originated, suggesting the birds first appeared in Australian and New Zealand waters about 22 million years ago before later spreading south into the cooler Antarctic waters.

A few years ago researchers discovered bacteria in Antarctica that could survive on nothing but air. Now the team has found evidence of this handy ability in other cold desert locations. The finding could have implications for life beyond Earth.

Scientists at the University of Buffalo have made a discovery that could shake up what we know about the sense of smell in humans, with the breakthrough focusing on a new type of taste cell with the ability to respond to different stimuli.

All kinds of fascinating discoveries are waiting in the deep sea. Now scientists have pulled a new monster out of the waters off the Indonesian coast. The creature is a new species of “supergiant” isopod, a huge marine relative of the common pillbug.
