Earth is around 60 million years older than previously thought -- and so is the moon, new research finds

Earth is around 60 million years older than previously thought -- and so is the moon, new research finds | Science, Technology, Internet | Scoop.it

Geochemists from the University of Lorraine in Nancy, France have analysed xenon gas found in South African and Australian quartz, which had been dated to 3.4 and 2.7 billion years respectively. The gas sealed in this quartz is preserved as in a "time capsule," allowing researchers to compare the current isotopic ratios of xenon, with those which existed billions of years ago. Recalibrating dating techniques using the ancient gas allowed them to refine the estimate of when the Earth began to form. This allows them to calculate that the Moon-forming impact is around 60 million years (+/- 20 m. y.) older than previously thought.

Dutch Scientists Achieve Quantum Teleportation Breakthrough

Dutch Scientists Achieve Quantum Teleportation Breakthrough | Science, Technology, Internet | Scoop.it

We may not have Star Trek-esque transporter technology any time soon—or ever—but Dutch researchers this week reported a breakthrough in the quantum teleportation of information, opening the door to a potential revolution in computing and networking.

Scientists at the Delft University of Technology's Kavli Institute of Nanoscience managed to transfer information contained in one quantum bit, or qubit, to another "entangled" qubit about 10 feet away "without the information having travelled through the intervening space," Prof. Ronald Hanson, head of the research group wrote in a summary.

In other words, as Hanson noted, "teleportation."

Tiny human brain models grown in lab with tiny cortex, tiny hippocampus (video)

Tiny human brain models grown in lab with tiny cortex, tiny hippocampus (video) | Science, Technology, Internet | Scoop.it

Through stem cells, the Institute of Molecular Biology (IMB) in Austria has managed to grow some tiny (3-4mm) human brain models that include parts of the cortex, hippocampus and retinas. The lab-grown tissue will allow researchers to peer into the early stages of human brain development in far higher detail than ever before.
