Bacteria Being Studied at KU
Bacteria thought to be one of the oldest forms of life on earth are being studied by a University of Kansas biochemist and engineer who works with scientists an idea of what sort of life they might find on other planets. Richard H. Himes and James Akagi are collaborating on the project which is funded by the NASA's Artemis matrices and Space Administration.
... possibly one of the oldest forms of life
The bacteria under study belong to the genus Clostridia. Some species of Clostridia are organisms that inhabit, heat organisms with best at temperatures which would ordinarily be lethal. Although these are soil bacteria, most of the other factories because of their resistance to the heat of the canning process. The optimum temperature for thermophile's about 140 degrees Fahrenheit.
Dr. Himes, associate professor of biochemistry, is interested in thermophiles because of their unique enzyme system. Enzymes can be used to catalyze cell reactions; they help break down food and synthesize substances that cells need. Most enzymes work well at the temperature of the human body, 98.8 degrees Fahrenheit, but they are damaged at 130-140 degrees.
The particular enzyme that Dr. Himes is studying, triosephosphate isomerase, is involved in the differentiation of active at temperatures up to 175 degrees Fahrenheit. The difference in the enzyme which is responsible for it together at temperatures is probably one small structural component, an aliphatic taper that it together at higher temperatures enzyme has a molecular weight of about 45,000-50,000 and consists of 500 amino acids linked together.
Besides thermophilic bacteria, there are other organisms that live in extreme environments. Dr. Himes said. Dr. Akagti is the first biochemist on sulfa on sulfate and produces hydrogen sulfide gas. The Great
Salt Lake, the hot springs of Yellowstone and the Arctic tundra all have their own peculiar forms of life. Another species of Clostridia which can survive at temperatures around freezing
Because the organisms live under such harsh conditions on earth, space scientists believe they may be similar to life forms that appear to be unique in the solar system because of its supply of water and oxygen, its mild temperature and its common life forms which are probably not found elsewhere, might be found elsewhere.
Hardy bacteria such as theromophiles are also anaerobic; contact with oxygen in the air is

It said the ship has been put in orbit around the earth. Scientific evidence suggests it should link up shortly with the unmanned "Salute" satellite which is now moving closer to Earth.

New Craft Being Built For Space

Students in the aerospace engineering at the University of Kansas are building a new type of drone—a set of wings without a body.
The machine, called a lifting body, will be a model for a spacecraft. The spacecraft will have two advantages over the type of capsule now in use. It could be used more than once. The spacecraft is also a landing spot after re-entry into the Earth's atmosphere.
Private industries have been granted $200 million for research to create a re-usable spacecraft similar to a lifting body.
The material from which past U.S. spacecraft were built was not re-usable because it burned during re-entry.
There are two types of lifting bees, a plane without wings and a drone with wings. Steve Gary, Baltimore senior majoring in aerospace
The craft being built by KU engineering students is a 3-foot set of silk-covered balsa wood wings without a body.
The uses of the craft are almost unlimited, Gary, the designer of the craft, said. He said it could be used as a rescue engine in space with an X-15 rocket engine, or as a lifesaving boat in a space station and the earth.
Interplanetary exploration would be possible if the plane was equipped with powerful booster rockets.
Tests will be conducted on a wind-tunnel version of the model before the end of this semester. The prototype will then be flown.
"Control problems may exist with the model," Gary said, "but in theory it works and there is no reason for failure in the model."

This natural process normally takes thousands of years. Koevingen said, but with the addition of stimulants such as nicotine and an alcohol population, the process speeded up to less than 100 years.
Phosphates are not the only problem. Last year Angina, a condition in which patients studied compounds of arsenic in the Kansas River and discovered concentrations close to those reported by the Public Health Service.
The Public Health Service sets the safe level for drinking water at 10 parts per billion (ppb) and Angino found concentrations in the river ranging from two to ten between Topeka and Lawrence.

He said that blue-green algae normally existed in competition with single-celled algae. One of the two blue-green algae population from crowding out the single-celled algae is the low phosphate concentration. When enough phosphates are dumped into the water, the blue-green algae can grow freely and the single-celled variety, he said.
interviews described how detergents contribute to the rising concentrations of phosphates and arsenic.
Phosphate levels in detergents and their relation to green algae growth in polluted waters have been studied by ecologists. Several surveys of phosphate levels have been conducted by different groups, companies who make low-levee phosphate detergents, Koevingen detergent.
Eutrophication, Koevingen said, is a term applied to lakes that are undergoing an aging process. The lake's organic matter is excess of excess algae growth; the oxygen
"We said it was a potential danger, not a pollutant," Angino said. "The sewage treatment plant is down." It is dumped back into the river." It is dumped back into the river."
*Limiting factors* are keys to the rapid growth of blue-green algae when excess phosphates are added to the water. Koeveng
THE BLUE-GREEN algae, Koevinge and are slime producers and don't enter into the food chain as fast as the single-celled variety. They also make produce bad odors and are toxic.
Surveys Misleading
ANGINO EXPLAINED that arsenate was the common substance that this form was relatively harmless. But, he said, if the arsenic is found with high concentration have depleted the oxygen supply, then the compound arsenate changes to arsenite which is very toxic.

Topeka dumps sewage into the Kansas River and Lawrence, downstream, takes two-thirds of its water supply from that same river. But the Kansas River is relatively clean, Angi said, and will help to arrest the threat that a swine will turn to arsenite in the Kansas River.

HE SAID SOME of the surveys were misleading. Instead of determining the phosphate content of detergents, he said, reliable surveys should include how much detergent is needed for each washboard and then find out whether the amount in each measure of soap used.
