No matter what humans come up with, chances are nature has already done a better job. Now researchers have discovered the latest example – beetles naturally lubricate their knees with a strange substance that works better than Teflon.

Just like a tree trunk, the tusk of the narwhal acquires a new growth ring every year. Analyses of those rings have now revealed some interesting facts about the animals' diet, and about changes in their environment.

We all know that bats locate prey in the dark using echolocation, but … is that really all there is to it? Scientists decided to get more details on the animals' hunting process, by equipping them with tiny wearable computers.

New research has found the bitter characteristics of coffee can make a person more sensitive to sweetness. The study found this effect was independent of caffeine and helps explain why many people enjoy the experience of dark chocolate with coffee.

Scientists in Denmark have now offered further insights into how sugar reshapes our brain chemistry, by performing experiments on pigs and taking note of how the reward circuitry lights up after consumption.

A new study indicates that ants can be very effective at protecting crops from diseases. It's even being suggested that ant-derived antibiotics could be applied on a commercial scale.

Scientists have used a drone to calculate the weight of live whales as they're swimming.

​According to an international understanding, all offshore oil rigs, wind turbines and other structures must be removed from the environment once they're no longer functional. A new study, however, claims that it might be better for marine life if such decommissioned installations just stayed put.

Researchers have revealed the mechanism behind an antibody that can potentially inactivate the body's allergic processes.​ The breakthrough brings researchers one step closer to developing a universal treatment that can prevent the fundamental immune response at the heart of all allergic reactions.

A team of researchers has discovered that Earth-sized exoplanets orbit their parent stars in the same way that our planet orbits our own Sun. The discovery further narrows the characteristics of worlds that could potentially play host to extraterrestrial life.

Every spring in Antarctica, mats of algae form on the underside of the sea ice. These mats serve as a food source for zooplankton, essentially kickstarting the food chain for the year. Scientists have set out to better understand the algae's distribution, using a high-tech underwater drone.

Chemical engineers have found a 30-year-old recipe that stands to make future hydrogen production cheaper and greener. Researchers have discovered a way to liberate hydrogen from water via electrolysis that does not require the expensive metal platinum.
