Italian archeologists said an ancient staircase made of marble was uncovered during excavations beneath Rome's Piazza Venezia.
Rome Archaeological Superintendent Angelo Bottini said the staircase, inset into pink granite and travertine, was discovered during work on a station for Rome's newest metro line. Bottini told ANSA it is an important find.
"It must have been an entrance into an important place but we have to find something in ancient sources if we are to make any circumstantiated hypothesis,'' he said.
The Italian news service said the subway construction project has turned up a trove of archeological treasures over the past 10 months, including Roman taverns, medieval kitchens and remains of Renaissance palaces.

Molecular DNA Switch Found to be the Same for All Life
The molecular machinery that starts the process by which a biological cell divides into two identical daughter cells apparently worked so well early on that evolution has conserved it across the eons in all forms of life on Earth. Researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and the University of California at Berkeley have shown that the core machinery for initiating DNA replication is the same for all three domains of life - Archaea, Bacteria and Eukarya.

Study Pushes Appearance of Northern Hemisphere Ice Sheets Back By 22 Million Years
(PhysOrg.com) -- Climatologist Robert DeConto of the University of Massachusetts Amherst and colleagues at four institutions are reporting in the Oct. 2 issue of the journal Nature that their latest climate model of the Northern Hemisphere suggests conditions would have allowed ice sheets to form there for the last 25 million years, or about 22 million years earlier than generally assumed. Their research has implications for the evaluation of global climate change.
A new dinosaur species, Pachyrhinosaur lakustai, unveiled from Pipestone Creek, Alberta, Canada
The fossils revealed a herd of dinosaurs that perished in a catastrophic event 72.5 million years ago. The animals are characterized by a bony frill on the back of the skull ornamented with smaller horns. They also had large bony structures above their nose and eyes which lends them their name: Pachyrhinosaurus (thick-nosed lizard). These structures probably supported horns of keratin.
