Eyring honored

The late chemistry professor Henry Eyring of the University of Utah has been recognized as one of the world's "top 75 distinguished contributors to the chemical enterprise."

The listing by the American Chemical Society puts Eyring's name beside that of Marie Curie and Linus Pauling. The list was compiled from nominations by readers of the society's weekly magazine, Chemical & Engineering News.

Eyring was famous for his development of an absolute rate theory on chemical reactions and other processes. A member of the National Academy of Sciences, he published more than 600 papers and half a dozen books. In December 1980 - a year before he died - the U. named the chemistry building in his honor.

Weighty thoughts

Four minutes spent walking upstairs instead of taking an elevator burns 80 calories.

Half an hour vacuuming incinerates 120 calories.

Five minutes taking out the trash would burn 15 calories (assuming it takes five minutes to do that simple chore).

A woman can calculate her target weight by taking 100 pounds and adding to this five times the number of inches she is tall above five feet. Men can do it by taking 106 pounds and adding to it six times the number of inches they are over five feet tall. Add 10 percent for a large frame, subtract 10 percent for a small frame.

More cancer in Utah

The American Cancer Society's annual "Facts and Figures" predicts that 5,200 Utahns will be diagnosed with cancer this year, an increase of 100 over last year's total.

"Colorectal cancer (cancer of the colon or rectum) is expected to increase from the 1997 estimate of 560 to the 1998 estimate of 600 new cases," said Barbara Alexander of the society's Utah affiliate. Nationally, rates of this often-deadly form of cancer have been dropping because of better screening and the consequent removal of polyps.

Alexander said that starting at age 50, men and women should get screened. "Colorectal cancer signs and symptoms may include rectal bleeding, blood in the stool or a change in bowel habits. Any of these should be evaluated by a physician," she said.

Galileo error

NASA scientists announced Friday they have received photos and other information transmitted by the Galileo spacecraft, data recorded during its Dec. 16, 1997, flyby of Jupiter's ice-locked moon Europa. The transmission was slowed by an on-board anomaly.

According to the Jet Propulsion Laboratory, Pasadena, a hardware glitch in one of Galileo's two gyroscopes affected the aiming of the scan platform and the spacecraft itself. "The gyroscopes are used to point the spacecraft when very precise pointing control and knowledge of the spacecraft's position and orientation are needed," says the JPL announcement.

Experts on Earth will study the anomalies to discover whether they could recur, and to develop work-arounds to prevent their happening during the rest of the mission. Meanwhile, Galileo's orbit around Jupiter was successfully adjusted on Jan. 22 to prepare for its encounter with the moon Europa on Feb. 10.

"Special precautions were taken in the design of this maneuver to minimize its vulnerability to any gyro problems," JPL adds.
