We all know the Darwin fish, the car-bumper send-up of the Christian "ichthys" symbol, or Jesus fish. Unlike the Christian symbol, the Darwin fish has, you know, legs. Har har.

But the Darwin fish isn't merely a clever joke; in effect, it contains a testable scientific prediction. If evolution is true, and if life on Earth originated in water, then there must have once been fish species possessing primitive limbs, which enabled them to spend some part of their lives on land. And these species, in turn, must be the ancestors of four-limbed, land-living vertebrates like us.

In a north London hospital, scientists are growing noses, ears and blood vessels in the laboratory in a bold attempt to make body parts using stem cells.

It is among several labs around the world, including in the U.S., that are working on the futuristic idea of growing custom-made organs in the lab.

While only a handful of patients have received the British lab-made organs so far— including tear ducts, blood vessels and windpipes — researchers hope they will soon be able to transplant more types of body parts into patients, including what would be the world's first nose made partly from stem cells.

A materials scientist at Iowa has developed electronics and materials able to dissolve on command.

Reza Montazami, assistant professor of mechanical engineering Iowa State University, calls the technology "transient materials" or "transient electronics." He says it could be used to create medical devices that disappear inside the body and are disposed of once they've done their jobs. Or the materials could be used by the military to send and receive top secret information.

Entering the Massachusetts Institute of Technology’s Center for Theoretical Physics by the front door, one passes more than a dozen well-used blackboards, meeting areas and offices before finding Alan Guth’s.

So when Harvard University astrophysicist John M. Kovac in February wanted to secretly meet with Guth, the originator of a key theory explaining the cosmos, he climbed up a stairway of MIT’s Building 6 and slipped through a back door on the third floor. Kovac, 43, then revealed a discovery that has since made Guth a star theoretical physicist.

Researchers have discovered a deep saltwater ocean on one of the many small moons that orbit Saturn, leading scientists to conclude it is the most likely place in the solar system for extraterrestrial life to be found.

Gravitational field measurements taken by Nasa's Cassini space probe revealed that a 10km-deep ocean of water, larger than Lake Superior, lurks beneath the icy surface of Enceladus at the moon's south pole.

David Stevenson, a planetary scientist at the California Institute of Technology in Pasadena, said the body of water was so large it "may extend halfway or more towards the equator in every direction. It might even extend all the way to the north."

NASA and the Russian Federal Space Agency have worked together for years in space, but that relationship may be radically changing as the situation in Ukraine continues to deteriorate.

The U.S. will suspend some space-related contact with Russia. However, the countries will continue working together on the International Space Station, where both American and Russian astronauts are currently living together.
