*Stem cells may be powerful gene shuttle
Stem cells may be a better shuttle than viruses for delivering corrective genes to tissues throughout the body, say HHMI researchers. The study hints that adults may harbor stem cells from a variety of organs and tissues that might be manipulated to heal genetic defects in organs and tissues throughout the body. http://www.hhmi.org/news/stemcell.htm

*Nanovation Technologies is listed in an article about the 4 top stocks of
the next decade. "Enter now a private company called Nanovation Technologies that proposes to eliminate digital gridlock by introducing new networking semiconductors and switches powered by speedy pulses of light rather than pokey old electrons. A reader named McNally, writing from British Columbia, suggested this one, noting that the firm is "not listed, but on the bottom rung of the electronic to photonic computer transformation. Important patents in place."

*With its Lunar Retriever I mission, Applied Space Resources is
developing a core competency in the use of existing technologies for the development of resources in near-Earth space. ASR is focused on delivering spacecraft to any destination with precision, and returning resources and information with equal precision, for a profit. Additional information, including various space policy papers, is available on the company's web site at http://www.appliedspace.com.

http://ganglion.med.cornell.edu/Aplysia/db-home.html Researchers at Cornell University Medical College are developing "an Internet-accessible database of electrophysiological and other information describing cortical neurons and their characteristic responses to somatosensory and other stimuli." The homepage describes the Cortical Neuron Database Project (part of the Human Brain Project), including the Common Data Model (Java), Vocabulary for Neuroscience Metadata, and a series of the project's research abstracts (.pdf) to be presented at the 1999 Human Brain Project Conference in October. Interested viewers should also check out The APLYSIA Project page, which describes the development of a similar (invertebrate/ molluscan) Web-accessible database. The Aplysia project database will enhance identification of molluscan neurons, the largest and best-studied nerve cells in the animal kingdom.
*Science for Tomorrow's Society
http://www.britishcouncil.org/virtual/science/index.htm The British Council hosts a series of virtual publishing exhibitions on the Internet, the latest of which is entitled Science for Tomorrow's Society. Due to be replaced in October 1999, this exhibition represents a succinct selection of UK-published science titles covering subject areas that promise to impact the future. A section on Award-winning Books features books for both children and adults that have won or been short-listed for a major award. For example, last year's winner of the Science Book Prize, The Consumer's Good Chemical Guide, is described here. Other sections include Biotechnology and Bioscience, Information and Communication Technology, Public Understanding of Science, and Science Policy and Exploitation. Depending on the section, titles are aimed at both professional and general audiences.

*Evidence that a free-running oscillator drives G1 events in the budding
yeast cell cycle
STEVEN B. HAASE AND STEVEN I. REED (nature) In yeast and somatic cells, mechanisms ensure cell-cycle events are initiated only when preceding events have been completed. In contrast, interruption of specific cell-cycle processes in early embryonic cells of many organisms does not affect the timing of subsequent events, indicating that cell-cycle events are triggered by a free-running cell-cycle oscillator. Here we present evidence for an independent cell-cycle oscillator in the budding yeast Saccharomyces cerevisiae. We observed periodic activation of events normally restricted to the G1 phase of the cell cycle, in cells lacking mitotic cyclin-dependent kinase activities that are essential for cell-cycle progression. As in embryonic cells, G1 events cycled on schedule, in the absence of S phase or mitosis, with a period similar to the cell-cycle time of wild-type cells. Oscillations of similar periodicity were observed in cells responding to mating pheromone in the absence of G1 cyclin (Cln)- and mitotic cyclin (Clb)-associated kinase activity, indicating that the oscillator may function independently of cyclin-dependent kinase dynamics. We also show that Clb-associated kinase activity is essential for ensuring dependencies by preventing the initiation of new G1 events when cell-cycle progression is delayed.
*Earthquake hits computer chip plants, world prices may rise. The Taiwan
earthquake means computer-chip makers will lose up to two weeks of production and could lead to an increase in worldwide prices, analysts said Wednesday. The quake knocked out power at most companies in the the Hsinchu Science-based Technology Park. By Wednesday morning, only partial power had been restored to several leading chipmakers there. The U.S. investment firm [ Merrill Lynch ] said in a report that Tuesday's deadly quake would affect output for one to one and a half weeks.
Taiwan is expected to account for 10 percent of global production in value terms this year, the report said.
