NASA has just announced that MESSENGER, the first spacecraft to orbit Mercury , has confirmed the presence of ice covered by an unknown organic material inside craters near the planet's north pole - two major building blocks for life! One current theory is that the ice and organic material could have been delivered to Mercury aboard an asteroid or comet perhaps hundreds of millions of years ago. Of course there’s a lot of painstaking research involved in the findings, as well as other details about this and other theories, so you can get the full story here .

We are all aware that the Large Hadron Collider (LHC) is the most powerful machine on planet earth and not yet operating at its full capacity. Since 2008, scientists at the CERN physics lab have slowing been increasing the intensity of the particle beams, with each time seeming to break its previous record. It was but a few days ago that the LHC lit up the headlines once again for breaking a world record of beam intensity previously achieved by Fermi's Tevatron in Batavia, Ill. In 2010, the Fermi Tevatron set the record for a beam intensity of 4.024 x 10 32 cm -2 s -1 and the LHC recently broke that record on April 22nd at around midnight Geneva time by reaching a luminosity of 4.67 x 10 32 cm -2 s -1 .
On the seafloor near the Bahamas, researchers have discovered a single-celled organism about the size of a grape, and they say the unusual organism raises interesting questions about the evolution of complex, multicellular animals. The oversized protists were found at the end of long, linear tracks that appear to have been made by the slowly rolling amoebas; lead researcher Mikhail Matz says the tracks resemble fossilized impressions from over 1 billion years ago, which scientists had assumed were made by multicellular worms. “We were looking for pretty animals that have eyes, are coloured, or glow in the dark; instead, the most interesting find was the organism that was blind, brainless, and completely covered in mud,” he said [ BBC News ].
It's no secret that toxic, heavy, and expensive batteries are the Achilles' heel of electric vehicles.
