Study Highlights Use of Viruses as Tools for Drug Delivery and Material Science

Temple University

Researchers used a "gating mechanism" in the coats of simple viruses to remove the genetic material and turn the remaining protein coat into a delivery system for other organic substances, including drugs. Their loaded viruses can also be altered to target certain types of cells (like cancer cells).

Sea Slugs Need Love, Too

University of Texas Medical Branch at Galveston

Sea slugs--back-boneless, ocean-dwelling creatures that look like a large snail without a shell--produce a perfume-like chemical, called a pheromone, that makes them almost irresistible to one another and helps these normally solitary animals congregate to breed, scientists at University of Texas Medical Branch at Galveston have discovered. The chemical is one of only a handful of known water-borne pheromones.

Researchers Synthesize Compounds for New Class of Antibiotics

Boston University

Researchers at Boston University and Scriptgen Pharmaceuticals, Inc., have successfully synthesized two compounds that open the door to the development of an entirely new class of antibiotics for use against today's increasingly drug-resistant bacteria as well as emerging forms of bacteria. In a recent issue of the Journal of Organic Chemistry, the research team reported that they have chemically synthesized myxopyronin A and B, two natural compounds known to block replication of drug-resistant strains of bacteria. Before this breakthrough, the compounds could only be isolated from their bacterial source, a process that yielded quantities too small to be usable.

The Distinctive Sound of Cholesterol

Rensselaer Polytechnic Institute (RPI)

Rensselaer has patented a device that listens to blood flowing in a patientís carotid artery and tells a doctor immediately if the artery is blocked by dangerous cholesterol deposits. The device provides an inexpensive, non- invasive screening system that doctors can use in their offices during routine checkups

Doubt Cast on Evidence of Life in Martian Meteorite Alh84001 by Study of Sulfides in Bacteria

Arizona State University College of Liberal Arts and Sciences

Martian meteorite ALH84001 was evidence for extraterrestrial life because minerals found in it resembled minerals created by unusual earthly bacteria. Now it appears that the bacteria themselves contradict that claim. An article in this week's Science reports that sulfides in the bacteria do not match the meteorite's minerals.

No Metallic Hydrogen Yet

Cornell University

The long-sought goal of turning hydrogen into a metal, it has been predicted, would require pressure comparable to that found at the center of the Earth. Researchers at Cornell University have now dispelled that theory: They submitted hydrogen gas to just such pressure, but the element remained unchanged.
