Despite their reputation for deadly attacks on humans and pets, alligators are wiggling their way toward a new role as potential lifesavers in medicine. Scientists report that proteins in gator blood may provide powerful new antibiotics to help fight infections associated with diabetic ulcers, severe burns, and “superbugs” that are resistant to conventional medication. See corresponding news release, abstract, and nontechnical summary for AGFD 32.

Expert foresees 10 more years of R&D to make solar energy competitive
Despite oil prices that hover around $100 a barrel, it may take at least 10 or more years of intensive research to reduce the cost of solar energy to levels competitive with petroleum, according to a leading expert on the topic. See corresponding news release, abstract, and nontechnical summary for PRES 063.

superheavy elements. Courtesy of Yuri Organessian.
Those exploring the uncharted seas at the fringes of the Periodic Table of the Elements have landed on one long-sought island — the fabled Island of Stability, home of a new genre of superheavy chemical elements sought for more than three decades. Researchers now are eying other islands on the more-distant fringes of the periodic table. See corresponding news release, abstract, and nontechnical summary for NUCL 007.

Meteorites delivered the “seeds” of Earth’s left-hand life
Desert heat, a little water and meteorite impacts may have been enough to cook up one of the first prerequisites for life: The dominance of “left-handed” amino acids, the building blocks of life on this planet. Ronald Breslow will describe how our amino acid signature came from outer space. See corresponding news release, abstract, and nontechnical summary for ORGN 001.

As nanotech goes mainstream, “toxic socks” raise concerns
Valued for its antibacterial and odor-fighting properties, nanoparticle silver is becoming the star attraction in a range of products from socks to bandages to washing machines. But as silver’s benefits propel it to the forefront of consumer nanomaterials, scientists are recommending a closer examination of the unforeseen environmental and health consequences of nanosilver. Paul Westerhoff, Ph.D. and Troy M. Benn will discuss the research. See corresponding news release, abstract, and nontechnical summary for ENVR 031.

Fungus fight: Researchers battle against dangerous corn toxin
At the 235th national meeting of the American Chemical Society in New Orleans, scientists presented advances towards the production of corn less susceptible to aflatoxin contamination. The new varieties could contribute to the reduction of the worldwide threat of the deadly toxin, improve food quality in developing countries and increase corn yield for food in the United States.

Protecting a life-saving blood product from human form of mad cow disease
Amid concern that recipients of certain blood transfusions may risk infection with a deadly protein responsible for the human form of mad cow disease, researchers in Canada now report development of a special filter that quickly and effectively removes the protein from blood. The use of the device will significantly decrease the risk of acquiring variant Creutzfeldt-Jakob Disease (vCJD), the human form of mad cow, through blood transfusions, the researchers say. See corresponding news release, abstract, and nontechnical summary for I&EC 064.

Biochemical signals associated with atherosclerosis may damage other organs
In a finding that challenges conventional medical knowledge, researchers report that plaques formed in during atherosclerosis, or hardening of the arteries, are associated with certain harmful chemical reactions that can contribute to damage in the lungs, liver, and other organs. The study suggests that the effects of the disease are more widespread than previously believed. See corresponding news release, abstract, and nontechnical summary for BIOL 152.
