2013/11/26 50 Meters of Optical Fiber Shrunk to the Size of Microchips

I came across this article on the Facebook page for DARPA, The Defense Advanced Research Projects Agency.  I usually have about one half hour to read before I leave to go into work.  This is what I found today while having my morning cup of Earl Grey tea.  Here is an excerpt.
"DARPA's iPhoD program reaches successful conclusion with demonstration of low signal loss records with microchip-scale, integrated waveguides for photonic delay"
"DARPA's integrated Photonic Delay (iPhoD) program created a new class of photonic waveguides with losses approaching that of optical fiber. The new waveguides are built onto microchips and include up to 50 meters of coiled material that is used to delay light. Conventional fiber optic coils of the same length would be about the size of a small juice glass. These waveguides also employ modern silicon processing to achieve submicron precision and more efficient manufacturing. The result is a new component that is smaller and more precise than anything before in its class."

Scientists Prove X-ray Laser Can Solve Protein Structures from Scratch | SLAC National Accelerator Laboratory

As I continue to read about interesting topics in my search for a future career, I came across this article published by SLAC National Accelerator Laboratory at Stanford University.   

"An international team of researchers working at the Department of Energy's (DOE) SLAC National Accelerator Laboratory produced from scratch an accurate model of lysozyme, a well-studied enzyme found in egg whites, using the Linac Coherent Light Source (LCLS) X-ray laser and sophisticated computer analysis tools."

Backstory: Marc Messerschmidt, Staff Scientist

As I continue to read interesting articles that catch my interest, I came across this video about the daily life at the SLAC National Accelerator Laboratory at Stanford University for the U.S. Department of Energy Office of Science.   

"Marc Messerschmidt, a staff scientist at the Coherent X-ray Imaging (CXI) experimental station at SLAC's Linac Coherent Light Source X-ray laser, describes his daily work."  (SLAC National Accelerator Laboratory).  I found this video on YouTube and on an article titled Scientists Prove X-ray Laser Can Solve Protein Structures from Scratch.

Beyond Quantum Simulation: JILA Physicists Create 'Crystal' of Spin-swapping Ultracold Gas Molecules

Beyond Quantum Simulation: JILA Physicists Create 'Crystal' of Spin-swapping Ultracold Gas Molecules

From NIST Tech Beat: September 18, 2013
The research was funded by NIST, the National Science Foundation, the Air Force Office of Scientific Research, the Army Research Office, the Department of Energy and the Defense Advanced Research Projects Agency.

"Described in a Nature paper* posted online on Sept. 18, 2013, the JILA experiment is the first to record ultracold gas molecules exchanging spins at a distance, a behavior that may be similar to that of intriguing solids such as "frustrated" magnets with competing internal forces, or high-temperature superconductors, which transmit electricity without resistance. The new results build on the same JILA team's prior creation of the first molecular quantum gases and demonstrations of ultracold chemistry.**"

Making the Triton Unmanned Aircraft System

As I continue to search for a better job opportunity, I am reading different company websites.  I found this video, the making of the Triton Unmanned Aircraft System at Northrop Grumman, on the Northrop Grumman website and YouTube channel.   Take a look at the video to watch how they  describe its capabilities.

2013/11/21 Chips meet Tubes: World 's First Terahertz Vacuum Amplifier

I just read a very exciting article about DARPA's  Terahertz Electronics (THz) program.  I am interested in pursuing a PhD and I think that I found a program that holds my interest.  Here is an excerpt from the article that can be found by clicking on the link below.  

"The achievement comes from DARPA-funded researchers at Northrop Grumman Electronic Systems, who built the 1 centimeter-wide traveling wave vacuum tube. The vacuum tube power amplifier is only one achievement of the broader THz program, which seeks to develop a variety of breakthrough component and integration technologies necessary to one day build complex THz circuits for communications and sensing."

Making the New Revolutions in Biology Safe - Council on Foreign Relations

This informative article was written by Laurie Garrett is senior fellow for global health at the Council on Foreign Relations.  Here is an excerpt of the article.  "Two revolutions are unfolding in biology, giving scientists the ability to turn existing germs into more dangerous ones with gained functional characteristics, and to synthesize new life forms entirely."
