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.

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.

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.

The eyes have it: Candidates’ eyes could be revealing

SternThe eyes may well be the window to the soul, but they also are indicators of the mind’s condition. People who have watched the presidential and vice-presidential debates earlier this month and preparing for the final debate on Oct. 13 could gather clues to the candidates’ state of mind by watching the candidates’ eyes. According to John Stern, Ph.D., professor emeritus of psychology at Washington University in St. Louis, and pioneer of blinking research, there is solid evidence that people blink frequently at points in time when they momentarily stop taking in and processing information.

Disrupting the ‘heart’s tornado’ in arrhythmia

A biomedical engineer at WUSTL has determined love taps are better than love jolts in addressing defibrillation.When it comes to affairs of the heart, love taps are preferred over love jolts. That is the result of a team of heart researchers including Igor Efimov, Ph.D., associate professor of biomedical engineering at Washington University in St. Louis, trying to effect a better implantable heart defibrillator. Efimov and his colleagues have modeled a system where an implantable heart defibrillator focuses in on rogue electrical waves created during heart arrhythmia and busts up the disturbance, dissipating it and preventing cardiac arrest.

Confirming by mineral dating

But much harsher ice ages hit the Earth in an ancient geological interval known as “the Cryogenian Period” between 750 and 600 million years ago. A team of geologists from China and the United States, including two from Washington University in St. Louis, now report evidence of at least three ice ages during that ancient time.

WUSTL leads group studying aging process

PakrasiA research team of biologists and engineers led by faculty at Washington University in St. Louis is seeking to find the Fountain of Youth — not in Florida, but in photosynthetic cyanobacteria (ancient little blue-green algae). Looking at the cellular systems in cyanobacteria, and then in a model plant and a moss species, these researchers want to determine how these organisms protect themselves from radicals, which are chemical culprits in the aging process in everything from bacteria to human beings.
