Software Promises Improved Refinery Modeling

HOUSTON, TEXAS--Boosting the octane number of gasoline just got easier, thanks to new software that lets engineers and scientists build a model of the naphtha reforming process in hours, rather than months, University of Delaware researchers reported March 13 during the American Institute of Chemical Engineers (AIChE) meeting. EMBARGOED: 4:00 p.m., Thursday, March 13, 1997.

When Satellites Mislead

Temperature-gleaning satellites are useful tools in the quest to diagnose global change, but only when their limitations are well understood. This is the message conveyed by scientists from the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, in an article appearing in the journal Nature on March 13. NCAR is managed by the University Corporation for Atmospheric Research under sponsorship of the National Science Foundation.

"Potential Microfossils" In Mars Meteorite

A new study on a Mars meteorite supports a low-temperature origin for carbonate globules inside the rock, researchers said today. This new evidence is consistent with theories that microscopic depositions in the rock may be the fossilized remains of bacteria. The research was published today in the journal Science. **EMBARGOED FOR RELEASE UNTIL 4 P.M EST, THURSDAY, MARCH 13, 1997**

"Shake Table" Shows Effects Of Earthquake

In Cornell University's concrete lab, a shake table was used to test, for the first time, whether interior infilled concrete/masonry walls have an effect on structural integrity during an earthquake.

When Models and Satellites Mislead

An article in Nature (13 March) by two NCAR scientists provides new findings on a controversy involving the reliability of global temperature trends available via satellite, which conflict with surface readings. In the same issue is an overview of how computer models of global climate are used and misused.

First Evidence That Ozone Hole Harms Antarctic Fish

Researchers supported by the National Science Foundation (NSF) have presented the first direct evidence that increased ultraviolet light (UVB) damages the DNA of animals in a natural population in Antarctica -- the eggs and larvae of icefish, an Antarctic fish lacking hemoglobin. The ozone hole opens up over Antarctica every southern spring, letting more UVB from the sun penetrate to the earth's surface.

Discovery of cell wall "scaffold" in filamentous

ATHENS, Ga. -- A botanist at the University of Georgia and a colleague at Purdue University have shown for the first time that filamentous fungi contain crucial "scaffold" proteins called septins. Perhaps even more important, the researchers have found that the gene which directs the production of septins in one fungus (Aspergillus nidulans) is crucial to the survival of the organism. The discovery could point toward a method of treating fungal diseases, which have dramatically increased in the past decade.

UD's Tiny Environmental Probe Measures it All

NEW ORLEANS, LA.--With a tip just 25 microns in diameter, a new microelectrode sheds light on the complex natural chemistry of "swamp scum and sea slime"--including the corrosive ocean "biofilms" that damage boats, docks and off-shore platforms, a University of Delaware researcher reported today during the National Association of Corrosion Engineers (NACE) meeting.
