- The academy said the discoveries of the two scientists may provide a method to destroy harmful RNA molecules that cause infections, such as the common cold.
- Superoxide is known as a free radical, a class of atoms and molecules that are missing an electron and thus are unstable.
- Atoms may also be assembled someday into molecules to create new substances and materials, they said.
- 'Then we screen only the molecules we think have a good chance of working.' Biotechnology methods can also be used to help build up a 'library' of molecules for screening.

- A team led by Dr. C. Spadafora at the Institute of Biomedical Technology in Rome reported that mouse sperm cells incubated in a solution with segments of foreign DNA could capture the DNA molecules.
- This complex of electrons and molecules all buzzing like mad and keeping me up on my two legs.
- We have now reduced the number to 30 molecules.' The company aims to bring products to market two to three years earlier than before.
- The buckyball bonanza really started last fall, however, when a team of German and U.S. scientists published an easy way to make the molecules in sizable quantities.
- So, the molecules are mixed with starch, which the bacteria or fungi can eat, breaking the plastic molecules down into smaller, bite-sized pieces.

- Liquid crystals are molecules that exist in a limbo world, part-way between the orderly state of a solid crystal and the amorphous phase of a liquid.
- But when electricity is applied to the liquid crystal, the molecules straighten and the light is again blocked by the filter.
- "The plant does try to replenish the molecules," Mattoo said. "But if you have higher UV-B radiation the plant will not keep up with the molecules that are being destroyed.

- Scientists hope that injecting the synthetic CD4 molecules would flood the body with "false targets" to divert the virus and keep it from infecting whole healthy T4 cells.
- Genzyme said the companies will try to improve a preliminary version of the drug using Genzyme's "carbohydrate remodeling technology," a method of altering molecules to make them more effective and safer as drugs.
- Such molecules take longer to develop than me-toos and there is a heightened danger of them being cut for reasons of safety and efficacy.
- Already selling 60 per cent of its product overseas, the underlying MTM businesses should enhance significantly BTP's standing as a niche chemicals company. BTP produces molecules for a multitude of industrial and consumer applications.
- Potential cost savings are estimated to be several billion dollars. MRT makes use of cavity-like molecules called ligands.
- The laser light moves the dye molecules, which in turn affect the liquid crystals next to them.
- Mostly, people at the institute are building computer models of complex phenomena. The models are supposed to show how molecules, markets or national economies evolve.
- This can put molecules of atmospheric gases into contact with satellites in low orbits and cause the craft to slow slightly and drop lower.
- The result often is chemical chaos, as each atom or molecule robbed of an electron becomes a free radical itself and instantly seeks electrons from still other atoms and molecules.
- Still other intermediary molecules, called transfer RNA, translate the information from messenger RNA into proteins, long chains of small molecules called amino acids.
