"Super-strong, highly conducting graphene is the hottest ticket in physics, but new computer simulations suggest that materials called graphynes could be just as impressive."
Physics - Graphyne May Be Better than Graphene


"Uturuncu, or Uturunku, the highest summit in southwestern Bolivia, is a stratovolcano. ...Researchers have determined that a large, roughly circular "disc" of land surrounding the volcano, approximately 70 km across, has been rising at a rate of 1 to 2 cm per year since at least the early 1990s, making it "one of the fastest uplifting volcanic areas on the Earth"." http://en.wikipedia.org/wiki/Uturuncu

Flying pyramids

Intrinsic Stability of a Body Hovering in an Oscillating Airflow

Bin Liu, Leif Ristroph, Annie Weathers, Stephen Childress, and Jun Zhang
Published February 9, 2012
Synopsis: Floats Like a Pyramid, Physics, APS

"Writing in Physical Review Letters, Bin Liu and co-workers at New York University present results from experiments on an inanimate pyramid-shaped flyer, or “bug.” Their choice of the shape was made in view of previous experiments with tethered flight, which showed that pyramids could hover in an airflow."

Another Earth

Astrónomos europeos hallaron un planeta rocoso, como el nuestro que podría contener agua y vida a 22 años luz de la Tierra, en la constelación de Escorpio.
