Sponge can soak up and release spilled oil hundreds of times

A new material can absorb up to 90 times its own weight in spilled oil and then be squeezed out like a sponge and reused, raising hopes for easier clean-up of oil spill sites. |SOURCE| This contrasts with most commercial products for soaking up oil, called “sorbents”. These are generally only good for a single use, acting like a paper towel used [...] Read more

DNA could be the future of data storage

A full operating system and film stored on DNA were recovered with no errors. |SOURCE| The world is churning out so much data that hard-drives may not be able to keep up, leading researchers to look at DNA as a possible storage medium. DNA is ultra compact, and doesn’t degrade over time like cassettes and CDs. In a new study, Yaniv Erlich and Dina [...] Read more

The World's Oldest Fossils Unearthed in Canada

The 3.8-billion-year-old remains offer evidence that life formed on Earth just after the planet formed, at a time when Mars still had flowing surface water. |SOURCE| Geologists have unearthed the oldest fossils ever discovered, chunks of quartz that contain tiny tubes and filaments left behind by microorganisms between 3.77 and 4.3 billion years [...] Read more

Quartz Could Be the Solution to Why Our Magnetic Field Is So Old

Solving the magnetic field paradox. |SOURCE| A mystery concerning the age of our planet's magnetic field could now be solved, thanks to evidence that Earth's core produces crystals of silicon dioxide – better known as quartz. This suggests that shifting chemistry within the outer core's liquid rock mixture is affecting how it flows, and if the [...] Read more
