*Biotech Breakthrough? 'Buckyball shards' show promise for chemical
separations, Science paper suggests. A new carbon material, resembling bits of buckminsterfullerene or 'buckyball' molecules, suggests a cheaper, lower-energy method for generating enriched oxygen and nitrogen, crucial ingredients for the production of steel and chemicals, and for the preservation of foods and medicines, DuPont and UD scientists report Sept. 17 in Science.
*Rebuilding the body.Biomaterials with built-in receptors that can interact
with human cells at the molecular level could be used as scaffolding to help construct new cartilage and skin, according to Dr Richard France speaking at the British Association’s Festival of Science in Sheffield, UK. http://www.eurekalert.org/releases/iom-rtb091499.html
*Tracks in iron provide an insightful map of microbial world
Reading the narrow bands of iron found in some sedimentary rocks, scientists may have found a way to assess microbial populations across time and space, opening a window to the early history of life on Earth and possibly other planets.

*Is the 2-in-1 burster a masquerade? A NASA scientist finds a peculiar,
rapidly rotating neutron star -- a pulsar -- is acting quite a bit differently than it did in 1995, and is trying to understand why. http://science.nasa.gov/newhome/headlines/ast17sep99_1.htm
*Male Courtship Pheromone Identified. University researchers have discovered
one of the first pheromones in a vertebrate animal species that is produced by the male and helps him when courting a female, in this case making her more calm, receptive to mating and less apt to run away. http://www.sciencedaily.com/releases/1999/09/990917073722.htm
*Bubonic plague kills by cutting off cellular communication. Yersinia
pestis, the deadly bacterium that causes bubonic plague, kills by cutting off a cell's ability to communicate with other immune system cells needed to fight off the bacterial invasion. In a study published in the Sept. 17 issue of Science, University of Michigan scientists identify one protein responsible for the plague's lethal effect and the molecular family it targets.

*Blueberries help counter effects of aging. A secret of youth may be as
close as your nearby supermarket: blueberries. Elderly rats fed the human equivalent of at least half a cup of blueberries a day improved in balance, coordination and short-term memory, a study published in the Journal of Neuroscience said. A cup of blueberries is a normal serving. http://www.nandotimes.com/healthscience/story/0,1080,500035079-500056594-500 016635-0,00.html
*The increasingly ubiquitous digital camera has taken another step into the
future with the development of the first such camera that senses only ultraviolet light.
*Ultracool atoms caught acting strangely. IT MAY BE DEGENERATE, but
scientists are coaxing atoms into doing things that are most unnatural. Deborah Jin, a physicist at the University of Colorado at Boulder, has made a gas of particles behave strangely as a first step towards forming an intriguing new "degenerate" state of matter. http://www.newscientist.com/ns/19990918/newsstory11.html
*Boston University researchers have discovered a way to shape the noise
spectrum of analog signals for higher fidelity, achieving ear-rivaling dynamic range (DR) and virtually unbounded signal-to-noise ratios (SNRs) by using a variable-sized neural network. They claim that their neural network's DR is proportional to the number of its neurons, and SNR goes up exponentially with each added neuron. Thus, those two important sound-quality factors can be indefinitely increased, simply by adding neurons.
*Homes for Orphan Genes. Scientists are making progress in decoding the
human blueprint, but the function of many genes remains a mystery. Using sophisticated techniques, researchers are solving some of the puzzles, and getting closer to new treatments for such ailments as high blood pressure. http://www.latimes.com/excite/990916/t000082878.html
*(Book) Virtually every cell in virtually every human being contains 23
pairs of chromosomes, each embodying the genetic material that helps make us who we are. What better way, then, to tell the story of what it means to be human than through the story of these 23 pairs of tiny molecules? That is the premise of Matt Ridley's Genome.

*California governor Gray Davis on Thursday digitally signed into law a
bill that gives electronic signatures equal legal standing with traditional signatures produced with a pen. The Uniform Electronic Transactions Act, which goes into effect on Jan. 1, makes electronic signatures legally binding in many types of legal documentation - including state or local laws, rental agreements, and leases. A number of documents will still require a signature, such as wills and real-estate transactions. The newstory: http://www.techweb.com/wire/story/TWB19990917S0015 California adopted the Uniform Electronic Transactions Act, which it is hoped will reasonably soon be adopted by all or almost all of the states and therefore create a level of uniformity desirable for online commerce. For those who want to pursue this further, the text of the California statute is at
*New law requires British restaurants to identify genetically modified food.
LONDON (September 17, 1999 7:49 p.m. EDT http://www.nandotimes.com) - British restaurants and caterers will have to tell customers which of their dishes contain genetically modified ingredients under a new law that goes into effect Sunday. The use of genetically modified, or GM, ingredients in foods is being hotly debated in Britain. Polls indicate many people strongly disapprove, while many want at least further research to be conducted. GM foods are made from plants whose genes are manipulated in order to produce characteristics such as resistance to pests. Britain has yet to approve raising GM crops, but some imported ingredients do contain GM plants. Food Minister Baroness Hayman said on Friday that the new labeling requirements, like those that have applied to food sold at retail since September 1998, "will ensure that consumers are entitled to the same information when eating out as they expect when buying their own food in shops." Failure to comply with the new law can be punished by fines of up to $8,000. "The government is committed to ensuring that consumers are able to make an informed choice about the food they eat," she said.
*POOLED GENES | Britain should soon have a centralised database containing
samples of DNA donated by its citizens. The database, being planned by the Medical Research Council and the Wellcome Trust, will help researchers discover important disease-causing genes. The scheme will be different from the one that has caused controversy in Iceland. There, DNA and medical records of the entire population have been included in a database held by a single company, DeCode Genetics of Reykjavik. In Britain, samples will only be included if their donors consent, and the database will be open to all researchers.
*Same-sex emu 'couple' leaves experts stumped.
Two Australian male emus have set up a nest together, confounding experts who said Friday they did not know if the birds were homosexual, confused or simply practical. The two adult males have shacked up to care for a clutch of seven chicks in the Tidbinbilla Nature Reserve, south of Canberra. While wildlife officers are not yet convinced the males are homosexual, they can offer no explanation for the surprising move. "It's unusual for a male to adopt chicks that aren't their own, but the two males have paired up and are getting along very well," said wildlife officer and acting manager of Tidbinbilla Nature Reserve, Geoff Underwood. "One male is very accommodating - normally he would chase any other emu away from the chicks." Male emus normally take over rearing their young after female partners lay the eggs, protecting their babies from the outside world and especially other males. But Underwood said the pairing of two males was the first of its kind in the 25 years he had worked in the area. "It's a bit of a mystery," he said. "It is normally a sole male role, but it appears they are moving away from single-parent families. It is an ultra-modern family, but I don't think they are homosexual. The other male is just confused."
*(I thought this was kind of cool:)
YASARA is an interactive real-time molecular dynamics program, covering various topics in the
field of molecular modeling, protein fold calculation (based on NMR data), tertiary structure prediction, protein / DNA docking and parallel macromolecular dynamics.
The program has been developed during my thesis diploma at the Institute for Microbiology (University of Graz, Austria) and currently contains 60000 lines C- and Assembler-code as well as its own operating system (SOS - the Scientific Operating System).
