Saturn's Spongy Moon in New Light

Expect to see some stunning images of Hyperion, Saturn's odd, tumbling moon - as NASA's Cassini spacecraft made its final fly-by of the spongy moon.
According to the US space agency, the Cassini spacecraft was positioned at a distance of about 34,000 km from Hyperion.
The 168-mile or 267-km wide Hyperion rotates chaotically, tumbling unpredictably through space as it orbits Saturn.
The moons’ body has a very low density and weak gravitational field, making a close fly-by easier than with other moons.

Elastic, Anti-shock Batteries Made from Wood

Scientists have developed a new method for creating elastic high-capacity batteries from wood pulp.
A team of researchers, using nanocellulose broken down from tree fibres has produced an elastic, foam-like battery material that can withstand shock and stress.
One benefit of the new wood-based aerogel material is that it can be used for three-dimensional structures.

First Lab-made Version of Spider Silk Produced

Spider silk has been grown from genetically modified cells for the first time. The research company behind the feat believes it opens the way for the manufacture of super-strong, light and biodegradable materials within a few years.
In the current research, cells were taken from the mammary glands of dairy cows and genetically modified with spider genes to produce the proteins used to make spider silk. The proteins were then stretched and spun from an aqueous solution into fine silk fibres.
Spider silk is one of the strongest and most flexible materials in the natural world, five times stronger than steel by weight. It would be ideal for bullet-proof clothing, biodegradable fishing nets and medical materials, such as sutures.

Scientists to Explore Jupiter's Moon ‘Europa’

NASA has announced that researchers from the Planetary Science Institute will be studying Jupiter`s moon Europa.
According to NASA, the Europa mission slated to be launch in the 2020s, will orbit Jupiter while performing 45 Europa flybys over a three-year period with altitudes ranging from 25 kilometers to 2,700 kilometers.
