Washington University CubeSat readied for NASA/Air force competition

David Kilper / WUSTL PhotoFailure at a university is a word with bad connotations, unless you are involved in building experimental satellites that the U.S. Air Force and NASA find interesting. An aerospace engineer at Washington University in St. Louis who works with students building experimental spacecraft says student-built spacecraft, which he calls “university-class,” have a strong advantage over aerospace industry-built spacecraft: the freedom to fail.

Acid-resistant bug doesn’t give in to alcohol either

A chemist at Washington University in St. Louis has found surprisingly tough enzymes in a bacterium that “just says no to acid.” Acid resistance is a valued trait for both pills and human pathogens. The bacterium Acetobacter aceti makes unusually acid-resistant enzymes in spades, which could make the organism a source for new enzyme products and new directions in protein chemistry.

Researchers describe how natural reactor worked

To operate a nuclear power plant like Three Mile Island, hundreds of highly trained employees must work in concert to generate power from safe fission, all the while containing dangerous nuclear wastes. On the other hand, it’s been known for 30 years that Mother Nature once did nuclear chain reactions by her lonesome. Now, researchers at Washington University in St. Louis have analyzed the isotopic structure of noble gases produced in fission in a sample from the only known natural nuclear chain reaction site in the world in Gabon, Wes Africa, and have found how she does the trick.

Magneprint technology licensed to TRAX Systems, Inc.

Washington University in St. Louis has licensed a system developed by Washington University engineers that is meant to detect counterfeit credit cards by reading a unique magnetic “fingerprint” on the stripes of credit cards and other objects that carry magnetic information. The system — called Magneprint — was invented by Ronald Indeck, Ph.D., Das Family Distinguished Professor of Electrical Engineering at Washington University.
