November 18, 2012 — By fabricating graphene structures atop nanometer-scale “steps” etched into silicon carbide, researchers have for the first time created a substantial electronic bandgap in the material suitable for room-temperature electronics. Use of nanoscale topography to control the properties of graphene could facilitate fabrication of transistors and other devices, potentially opening the door for developing all-carbon integrated circuits.

November 8, 2012 — Corals under attack by toxic seaweed do what anyone might do when threatened – they call for help. A study reported this week in the journal Science shows that threatened corals send signals to fish “bodyguards” that quickly respond to trim back the noxious alga.

November 1, 2012 — Researchers are developing a technique for predicting from a simple blood sample the amount of cathepsins—protein-degrading enzymes known to accelerate certain diseases—a specific person would produce. This patient-specific information may be helpful in developing personalized approaches to treat these tissue-destructive diseases.

October 30, 2012 — Using a new method for precisely controlling the deposition of carbon, researchers have demonstrated a technique for connecting multi-walled carbon nanotubes to the metallic pads of integrated circuits without the high interface resistance produced by traditional fabrication techniques.
