There was an understandable amount of skepticism when Amazon announced its grand plans for delivery drones last year. But if the last twelve months are any indication, Jeff Bezos and his fellow tech heavyweights are actually kinda serious about the potential of unmanned aerial vehicles.

Traditionally robots have been big, powerful, metallic objects that might weld doors onto cars in a factory," Wood says. "The robots we explore are dramatically different, some on a new, micro-sized scale, others made of soft rather than rigid materials.

Different palaeolithic populations around the world might have developed a crucial toolmaking skill independently. This conclusion, based on the analysis of hundreds of artefacts from a recently excavated archaeological site in Armenia, weakens a long-held theory that Stone Age people in Eurasia learnt sophisticated techniques from migrating African tribes.

Neanderthals' capabilities are still hotly debated. Some argue that before modern humans replaced them, Neanderthals showed cultural capabilities similar to those of modern humans, while others make a case that these similarities only appear once Neanderthals came in contact with modern humans. "The new data from Willendorf clearly shows that modern humans were present in what is now Austria while Neanderthals still occupied other regions of Europe suggesting that the two species met, and may have exchanged mates and ideas", explains Philip Nigst. "This means the changes in the material culture of some of the last Neanderthal groups are most probably related to direct or indirect contact with modern humans".
Canyons, lakes and mountains have been revealed in the most detailed maps ever made of the hidden world beneath the polar regions.
Birds didn't evolve in one fell swoop from their dinosaur ancestors, suggests a newly constructed dinosaur family tree showing our feathery friends evolved very gradually, at first.
Black holes have long captured the public imagination and been the subject of popular culture, from Star Trek to Hollywood. They are the ultimate unknown – the blackest and most dense objects in the universe that do not even let light escape.

A star-explosion mystery that puzzled astronomers for more than two decades has finally been solved.
Physicists have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber. The experiment constitutes a first, and simply pulverizes the previous record of 6 kilometers achieved ten years ago by the same team. Passing from light into matter, using teleportation of a photon to a crystal, shows that, in quantum physics, it is not the composition of a particle which is important, but rather its state, since this can exist and persist outside such extreme differences as those which distinguish light from matter.
Physicists have used a quantum connection Albert Einstein called “spooky action at a distance” to link 500,000 atoms together so that their fates were entwined. The atoms were connected via “entanglement,” which means an action performed on one atom will reverberate on any atom entangled with it, even if the particles are far apart. The huge cloud of entangled atoms is the first “macroscopic spin singlet,” a new state of matter that was predicted but never before realized.
If there's one thing to be said for Curiosity's mission on Mars so far, it certainly hasn't been boring. From supposed Martian squirrels to strange flashes of light on the surface, the rover has kept us entertained. And now there's this rather odd... ball.

Astronomers have detected water vapour in the atmosphere of a planet that orbits a star far beyond our solar system.
The United Nations Educational, Scientific and Cultural Organization (UNESCO) is potentially wading into hot water next month when it hosts a meeting set up by Nobelist Luc Montagnier to discuss his controversial research on what has become known as "the memory of water."

The Mars Orbiter Mission, or MOM, was intended mostly to prove that India could succeed in such a highly technical endeavor — and to beat China. As Mr. Modi and others have noted, India’s trip to Mars, at a price of $74 million, cost less than “Gravity,” the Hollywood movie. NASA’s almost simultaneous — and far more complex — mission to Mars cost $671 milliony.

Mars has welcomed a new robotic visitor from Earth.
Looking across the Mars landscape presents a bleak image: a barren, dry rocky view as far as the eye can see. But scientists think the vista might once have been quite different. It may have teemed with water and even been hospitable to microbial life. What changed?
Altruism has posed a puzzle for psychologists and evolutionary biologists for centuries. Why is it that humans will help others even to their own detriment?
