CORRECTION."Device ups hydrogen energy from sunlight" (SN: 9/16/00, p. 182) gives the wrong publication date for the journal article describing a solar-to-hydrogen energy conversion device. The reference should have been to the Sept. 28 issue of the JOURNAL OF PHYSICAL CHEMISTRY B The Journal of Physical Chemistry B publishes scientific articles reporting research on the chemistry of materials, including nanostructures, macromolecules, statistical mechanics, and the thermodynamics of condensed matter, biophysical chemistry, as well as the structures and . The article was also posted on the journal's Internet site on Sept. 1. When even some governments deny the very existence of the problem of the grass pea's toxicity toxicity /tox·ic·i·ty/ (tok-sis´i-te) the quality of being poisonous, especially the degree of virulence of a toxic microbe or of a poison. , it is difficult to get interest from potential donors. Fernand Lambein Gent, Belgium Great Danes Great Dane, breed of very large, powerful working dog developed in Europe more than 400 years ago. It may stand as high as 36 in. (91.4 cm) at the shoulder and weigh up to 150 lb (68.1 kg). The last story in the Aug. 5 issue, "Danes keeping drugs out of livestock" (SN: 8/5/00, p. 95), deserves front-page status. Considering that antibiotics Antibiotics Definition Antibiotics may be informally defined as the subgroup of anti-infectives that are derived from bacterial sources and are used to treat bacterial infections. add to the cost of food, health care, groundwater cleanup, and the debt of poor nations, this is a potentially revolutionary development. The fact that the presence of antibiotic-resistant Enterococcus faecium Enterococcus faecium A nosocomial pathogen resistant to most antibiotics–eg, penicillin, teicoplanin, aminoglycosides, glycopeptides; ID of E faecium in a clinical specimen requires Pt isolation with barrier precautions. has decreased with the reduction in antibiotics use in Denmark and that the incidence of diseases that the antibiotics might have prevented have risen very little has global implications. The added cost of 75 cents to bring each pig to production is over-ridden by the savings in the cost of antibiotics. In my view, cost has the lowest priority. The health benefits are enormous.
