Yes, those balls. You know the ones I'm talking about. The man rocks, the family jewels, the subject of that ACDC song we've all tried to forget about. In the great mammalian sex race, a male with big balls is likely a very successful reproducer, being both dominant and popular with the ladies. New research has found that with mice, however, that this isn't always the case. The best balls, experts are now claiming, don't always take up a lot of space.
With growing fear of genetically modified organisms (GMOs) an unavoidable and understandable consequence of 'playing God,' researchers have been in pursuit of new ways to eliminate some of the real threats modified products could pose to the natural world. Now, two separate teams of researchers have designed unique "kill switch" systems that would automatically eliminated escapee experimental GMOs.
Slow-moving and lacking typical fighting parts, cone snails are not your average fearsome predator; but that doesn't mean they aren't lethal. These fish-eating sea snails make up for their inadequacies by using a unique kind of weaponry that delivers a toxic dose of insulin to effectively disable their prey, a new study finds.
The giant kangaroo, a species that once roamed the Australian outback over 40,000 years ago, has long been extinct, but thanks to scientists that extracted its DNA for the first time we are learning more about this marsupial megafauna.
Human divers have long known that they risk heart trouble every time they make for deeper depths. Holding your breath places strain on your heart, and the longer you do it for during physical exertion, the more you risk. Now new research has found that even mammals meant for deep-diving, like seals and dolphins, run these risks, proving that there are some things the heart simply cannot overcome.
US Farmers that are currently fighting ongoing drought, particularly in California, may have hope yet thanks to one man's ingenious invention.
Researchers didn't know it until now, but two miles under the sea lies a new sulfate-breathing species, revealing just how little we really know about the ocean, new research shows.
Insect-eating pitcher plants found in Borneo may seem brainless, but these carnivorous plants are cleverer than you think, a new study says.
Bisphenol A, a chemical known as BPA that's commonly used in consumer products, reportedly affects brain development in young zebrafish, causing concern that it can also negatively impact human brains still developing in the womb, according to new research.
Fish apparently use a "sixth sense" to detect water flows, solving a long-standing mystery of how these aquatic creatures respond to their environment, according to a new study.
Researchers are suggesting that bee keepers should start breeding their bees to be more hygienic, as this could potentially help protect them from the dangerous parasitic mites that have been kicking struggling honeybee populations while they're down.
Geckos are known for their extremely adept climbing talents, able to scale walls and ceilings, but new research shows that over the course of evolution some gecko species can lose their stick.
In the longest case ever seen of sperm storage, a female shark at the California Academy of Sciences' Steinhart Aquarium delayed fertilization for an astonishing four years, giving conservationists hope for the future of shark species everywhere, new research shows.
In the case of one butterfly, it doesn't know what it wants. That's because this beautiful insect boasts both genders on each side of its body, making it half male, half female, new research shows.
Fertilization has always been seen as a race to the egg, where only the fittest and fastest sperm will be ever be able to naturally lead to new life. However, a new study has revealed that in the case of birds, this may not be the case. Instead, the longest and biggest avian sperm seems to get eggs "cooking," so to speak.
