Scientists worldwide are struggling to make motor fuel from waste, but Richard Gross has taken an unusual approach: making a “fuel-latent plastic,” designed for conversion. It can be used like ordinary plastic, for packaging or other purposes, but when it is waste, can easily be turned into a substitute diesel fuel. The process does not yet work well enough to be commercial, but the Pentagon was impressed enough to give $2.34 million for more research. The technique could reduce the amount of material that the military has to ship to soldiers at remote bases, because the plastic would do double...

Source: Brookhaven National Laboratory Date: October 31, 2006 Scientists Convert Modern Enzyme Into Its Hypothesized Ancestor By making a single substitution in the amino acid sequence of a modern enzyme, scientists have changed its function into that of a theoretical distant ancestor, providing the first experimental evidence for the common origin of the two distinct enzyme types. The research, conducted by a team that includes scientists from the U.S. Department of Energy's Brookhaven National Laboratory and the Karolinska Institute in Stockholm, Sweden, will be published online the week of October 30, 2006, by the Proceedings of the National Academy of...

An enzyme known to be critical for the repair of damaged cells and the maintenance of cellular energy may be a useful target for new strategies to treat Huntington's disease (HD) and other disorders characterized by low cellular energy levels. In the August issue of Chemistry & Biology, a research team from the MassGeneral Institute for Neurodegenerative Disease (MIND) describes their discovery of a novel inhibitor of Poly (ADP-ribose) polymerase (PARP1) and their findings that PARP1 inhibitors can protect HD-affected cells from damage in laboratory assays. "While PARP1 is essential for the repair of damaged DNA, we also know that,...

A year ago, a mystery virus began to kill people in China. Causing an illness dubbed severe acute respiratory syndrome (SARS), the virus quickly spread beyond Asia and for a few months stirred fears of a worldwide epidemic. With stunning speed, scientists identified the virus and decoded its genetic sequence (SN: 4/26/03, p. 262: http://www.sciencenews.org/20030426/fob8.asp). Now, a research team has claimed victory in the race to identify the cellular receptor—the protein to which the virus attaches when it infects cells—for the SARS virus. Since the protein turned out to be a well-known one that had previously been implicated in heart...

An enzyme-catalysed battery has been created that could one day run cell phones and laptop computers on shots of vodka. The key to the device is a new polymer that protects the fragile enzymes used to break down the ethanol fuel, scientists told the American Chemical Society's annual meeting in New Orleans on Monday. Enzyme-based batteries have the potential to be cheaper than fuel cells that rely on expensive platinum or ruthenium catalysts. "It sounds great," says Bob Hockaday, founder of the company Energy Related Devices and designer of a methanol-powered battery. "Enzymes are inexpensive and catalytically very active." Fuel...

Vostok: The Lake of ShadowsCover Story FATE Magazine 2002-06-01 00:00:00 by Scott Corrales “Doubt of the real facts, as I must reveal them, is inevitable; yet if I suppressed what will seem extravagant and incredible there would be nothing left.” —H. P. Lovecraft, “At the Mountains of Madness” The inspiration for this article began in the summer of 1996, when a series of email messages began to appear suggesting the possibility that “someone” or “something” was surreptitiously removing all recent maps of Antarctica. The notion was so outrageous that even die-hard conspiracy theorists found themselves having to clarify the...
