DNA-Carbon Nanotube Hybrid

Single-stranded DNA and carbon nanotubes are chemically compatible and readily self-assemble into DNA-carbon nanotube hybrids (pictured here).  These materials have applications in nanoelectronics, medicine, environmental safety and homeland security.  Dr. Robert R. Johnson of the University of Pennsylvania has used computer simulation to study the structure of these nanomaterials.

 

MUSTANG - a Penn Radio Telescope Array

Penn,the National Institute of Standards and Technology, NASA's Goddard Space Flight Center, and the National Radio Astronomy Observatory, have built a 3 millimeter array of 8x8 TES detectors for the Green Bank Telescope (GBT).

 

DNA through a Solid State Nanopore

Dr. Meni Wanunu, Dr. Marija Drndic and others at the University of Pennsylvania have threaded DNA through solid state nanopores in order to gain information about chemically modified DNA. The image depicts chemically modified DNA translocating through a nanoscale pore in silicon nitride.

 

Dark Energy Survey

The Dark Energy Survey (DES) uses a 570-Megapixel digital camera at the Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory in the Chilean Andes to probe the origin of the accelerating universe. Penn scientists are among the 120 scientists from 23 institutions in the US, UK, Brazil, and Germany working on the project slated for first light in Fall 2012.

 

Large Hadron Collider - ATLAS Higgs candidate event

An event captured by the ATLAS detector in the search for a Higgs boson decaying into two Z bosons, one of which goes into a pair of electrons and two muons (the two tracks shown in red). There is no way to tell if this particular event comes from a Higgs decay or simply from a background event such as one containing two Z bosons.
