A new study has revealed that a human scream can convey a complex range of emotions beyond fear and danger. What's more, our brains perceive and respond to them in different and somewhat counter-intuitive ways.

A new study has found moderate consumption of fructose and sucrose can dramatically amplify fat production in the liver. The research also suggests these sugar-induced changes to fat metabolism can continue for long periods of time.

If one of the motors conks out on a quadcopter drone, the aircraft usually just crashes. Thanks to new research, however, such disabled drones could soon not only remain airborne, but even complete their trip.

Sharks pre-date even the earliest dinosaurs, so it's not surprising to hear that they've changed over the years. It was recently discovered, for instance, that they were once able to rotate the two sides of their jaw outwards, helping them to feed.

Scientists have developed a new navigation algorithm that enables unmanned quadcopters to pull off some impressive acrobatics, a training pathway they hope can help boost drone efficiency in areas such as search and rescue operations.

Measuring more than 5 m (16 ft) long, Titanichthys was a giant armored fish that swam the oceans 380 million years ago. It may sound intimidating, but new research suggests that it fed in a manner much like that of today's harmless basking shark.

Obstacle avoidance is crucial for drones, but most systems aren’t fast enough for some situations. Now engineers at the University of Zurich have developed a new system that gives drones such fast reflexes that they can play – and win at – dodgeball.

Researchers in Europe and the UK have managed to connect biological and artificial neurons together. The biological neurons were grown in Italy, sent signals through an artificial synapse in the UK to communicate with artificial neurons in Zurich.

In what is being touted as a major breakthrough, scientists have developed a machine that can not only keep livers alive outside the body for a week, but can also rejuvenate damaged livers unfit for transplantation.

New research suggests some asteroids could actually be alien, captured during close flybys with other star systems. These close encounters could also explain objects like Oumuamua and might even provide an alternative to the “Planet Nine” hypothesis.

Although quadcopter drones show promise as a means of exploring hazardous environments, they do have one drawback – they're wide, limiting their ability to squeeze through tight spaces. An experimental new drone addresses that problem, by folding into different shapes while in flight.

Jupiter may be the largest planet in the solar system, but it experienced growing pains. That's the conclusion of a team of scientists, who say that Jupiter grew in three stages with a two-million-year gap during which it grew very slowly, affecting the development of the rest of the solar system.
