Paleontologists discover new fossil organism

Posted: 09 May 2014 02:29 PM PDT

Paleontologists have discovered a fossil of a newly discovered organism from the Ediacara Biota. Plexus ricei was a broadly curving tube that resided on the seafloor. Individuals range in size from 5 to 80 cm long and 5 to 20 mm wide, and comprise a rigid median tubular structure and a fragile outer tubular wall. Plexus ricei evolved around 575 million years ago, disappearing from the fossil record around 540 million years ago.

Longevity gene may boost brain power: Researchers discover the gene may enhance cognitive abilities

Posted: 09 May 2014 12:08 PM PDT

Scientists showed that people who have a variant of a longevity gene, called KLOTHO, have improved brain skills such as thinking, learning and memory regardless of their age, sex, or whether they have a genetic risk factor for Alzheimer's disease. Increasing KLOTHO gene levels in mice made them smarter, possibly by increasing the strength of connections between nerve cells in the brain.
