Scientists unveiled Monday the gene in carrots that gives rise to carotenoids, a critical source of Vitamin A and the pigment that turns some fruits and vegetables bright orange or red.

The world's most powerful proton smasher is preparing for its biggest run yet which scientists hope will uncover new particles that could dramatically change our understanding of the Universe.

SpaceX successfully landed the first stage of its Falcon 9 rocket on a floating platform in the Atlantic Ocean early Friday after launching a Japanese communications satellite into orbit.

A bug over half a meter long discovered in southern China has been declared the world's longest insect, state media said Thursday.

SpaceX plans to launch early Friday a Japanese communications satellite into a distant orbit before attempting to land the first stage of its Falcon rocket on a floating platform in the Atlantic Ocean.

The liftoff is scheduled for 1:21 am (0521 GMT) from Cape Canaveral, Florida, the California-based company headed by Internet entrepreneur Elon Musk said.

An international team of scientists said Monday they had discovered a trio of Earth-like planets that are the best bet so far for finding life outside our solar system.

The three orbit an ultracool dwarf star a mere 39 light years away, and are likely comparable in size and temperature to Earth and Venus, they reported in a study, published in Nature.

Waist deep in sparkling blue water off the white beaches of the Indian Ocean spice island of Zanzibar, seaweed farmer Mtumwa Vuai Ameir gently ties seedlings to wood poles.

Large parts of Australia's Great Barrier Reef could be dead within 20 years as climate change drives mass coral bleaching, scientists warned Friday.

The World Heritage-listed reef is currently suffering its worst bleaching in recorded history with 93 percent of corals affected due to warming sea temperatures.

Russia's new Vostochny cosmodrome hosted its first rocket launch Thursday, the Roscosmos space agency said, after a last-minute delay a day earlier led to President Vladimir Putin criticizing the program's officials.

The Soyuz 2.1a rocket carrying three satellites took off at 11.01 am local time (0201 GMT), the national space agency said in a statement, after the countdown was automatically halted for technical reasons 24 hours previously.

Einstein's theory of general relativity is to be put to the test by a newly launched satellite in an experiment that could upend our understanding of physics.

The French "Microscope" orbiter will try to poke a hole in one of Einstein's most famous theories, which provides the basis for our modern understanding of gravity.
