Bobtail squidA molecule that triggers damaging changes in the lungs of children with whooping cough lets a bobtail squid living off the coast of Hawaii acquire the ability to glow, scientists have discovered.

He was named an assistant professor in 1951 and promoted to associate professor in 1957; he retired as emeritus in 1987.

Salmonella entericaEvery year in developing nations, typhoid fever infects more than 16 million people and kills more than half a million. Researchers hoping to reduce this heavy toll have an important new tool: completed genomes for the two bacteria that are the leading causes of typhoid fever.

Remembering Einstein’s “miracle year.”The United Nations has declared 2005 the International Year of Physics — and there’s a very good reason why this particular year was chosen to raise worldwide public awareness of physics. It is also the 100th anniversary of physicist Albert Einstein’s miraculous year in which he wrote five — or three depending on whom you ask — of his most famous scientific papers. Also known as the World Year of Physics, 2005 will feature worldwide events of interest not only to physicists, but also to the general public. Two physicists from Washington University in St. Louis who are both known for their ability to speak and write clearly about physics to the layperson will be giving talks throughout 2005 about Einstein’s ideas and their impact on science and society 100 years later.

Red jungle fowlThe first detailed analysis of the chicken genome has identified a chicken counterpart to an important human immune system protein, revised scientists’ assessment of the chicken’s sense of smell, and suggested that the chicken, long used to study gene activity in the earliest stages of life, may provide a good model for studying changes in DNA linked to aging and death.

Originating in Washington University research laboratories, St. Louis-based biotechnology company Apath has generated enough profit in just seven years to contribute $1 million in royalty payments back to the School of Medicine.

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.

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.

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.

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.
