UK firm ships ‘last’ sat-nav payload

Image copyright KATHRYN GRAHAM Image caption SSTL’s Galileo team is determined to avoid complacency and win further work UK satellite manufacturer SSTL has reached a key milestone in its work on Galileo, the EU’s version of GPS. The company has just shipped its 22nd navigation payload, and the last under its current work contract. Essentially […]

Satellite’s ice vision is boosted

Media captionThe new method delivers much more detail, at much greater speed European scientists have found a way to super-charge their study of the ice sheets in Antarctica and Greenland. The novel technique boosts the data about height changes that are gathered by radar instruments on satellites. Known as swath altimetry, it permits researchers to […]

Zika virus ‘shrinks brains’ in tests

Zika virus ‘shrinks brains’ in tests

Image copyright SPL Zika virus can enter the brains of mice in the womb to stunt development, the first animal tests show. The trio of studies provide crucial experimental evidence that backs up fears the virus is behind the surge in babies born with small heads in Brazil. They showed the virus could cross the […]

VIDEO: Dying coral reefs ‘dull fish senses’

Researchers in Australia and Sweden have found that coral bleaching and death can have a direct effect on how reef-dwelling fish learn about their environment – particularly how to avoid predators. The team from James Cook University in Queensland and Uppsala University carried out tests in enclosed “mini reefs” that simulated the environment they were […]

Swarm tracks Earth’s turbulent shield

Media captionSee areas of field intensity strengthen and weaken over 15 years Europe’s Swarm mission is providing an unprecedented view of Earth’s turbulent magnetic field, scientists say. The three-satellite constellation is now routinely mapping its convulsions, allowing researchers to probe the mechanisms that drive the “invisible shield” in remarkable new detail. Movies released this week […]

‘Weird’ OBJECT MOVING on its own JETS seen beyond Mars orbit by Hubble – Register

5 ways to prepare your advertising infrastructure for disaster Pic A bizarre spinning object, described by NASA as “weird and freakish” and shooting jets of matter that cause it to move, has been spotted in our Solar System. The mysterious rock, located in the asteroid belt between Mars and Jupiter, was seen spewing matter from […]

Your pee could power future robots – Fox News

There’s a new use for artificial hearts, and it involves a more taboo bodily fluid than blood. A device that mimics the squeezing action of the human heart has been used to pump urine into a microbial fuel cell, which could power robots that convert the waste into electricity. “In the future, we hope the […]

New hammerhead shark species found off South Carolina – Fox News

When new species are found near populated areas, they are often small and inconspicuous, not, for example, a hammerhead shark. But that’s exactly what a team of researchers discovered along the coast of South Carolina. The new species looks virtually identical to the scalloped hammerhead, but is genetically distinct, and contains about 10 fewer vertebrae, […]

‘Don’t panic’: One-tonne satellite falling to Earth – BBC News

A one-tonne satellite is falling out of control and is likely to crash into the Earth sometime during the weekend, scientists have warned. The Gravity Field and Steady-State Ocean Circulation Explorer was launched in March 2009, to study changes in sea level, ocean circulation and the planet’s gravitational field. It has now run out of […]
