*FEED magazine has an article on nanotechnology. "Thinking Small." Mark
Pesce (co-inventor of VRML) on molecular-scale manufacturing, the gray goo
problem, and how nanotechnology will change the world as we know it.

*Ultra-tiny machines are becoming big hope for scientists. After years of
preliminary research, hope and hype, business and industry are starting to
enter the strange, invisible world of the very ... Very ... VERY
small.Government agencies, leading universities and major corporations are
rapidly expanding their efforts to design and build machines and structures
on the scale of atoms and molecules. This exploding new discipline -- known
as ``nanotechnology'' -- has become a top scientific priority in Congress
and at the White House.

*Plastic Pillars of the Microworld. Rome wasn't built in a day, but a
nanosized version of it may be thrown up that quickly in the near future. At
the International Symposium on Cluster and Nanostructure Interfaces here
last week, researchers described a new technique capable of creating arrays
of plastic pillars, each less than a micrometer across, that resemble
nothing so much as tiny versions of the great columns of Rome's coliseum.

*Yale Research Team First to Describe Molecular-Sized Memory -- Discovery
has Implications for Drastically Reducing Cost of Computer Memory. omputer
storage capacity can be vastly increased using a molecular memory based on a
single molecule, a research team from Yale and Rice Universities has
discovered.
http://www.yale.edu/opa/newsr/99-11-02-01.all.html
*A miniaturized triode could instead replace the transistor as the switch of
information technologies. Driskill-Smith and colleagues have now fabricated
a ‘nanotriode’ tube measuring less than 100 nanometres (millionths of a
millimetre) in any direction.
http://helix.nature.com/nsu/991104/991104-3.html
*Making Robots Microscopic but Mighty. Michael J. Marsella is dreaming small
these days. The assistant professor of chemistry at UC Riverside is trying
to create artificial "muscles" no bigger than a single molecule.
http://www.latimes.com/news/science/science/19991108/t000101547.html
*Chemical researchers build molecular computer. A molecular electronics
research project at Mitre Corp. has achieved a milestone in the effort to
build self-assembled molecular computers. Researchers James Ellenbogen and
Christopher Love have invented chemical building blocks that support the
operation of a digital half adder, which represents a new level of circuit
complexity for the field.
http://www.eet.com/story/OEG19991109S0036
*How Biological Molecules Move Electrons: Simplicity Trumps Complexity. In a
sweeping new study, researchers at the University of Pennsylvania Medical
Center have shown that the natural engineering principles governing electron
transfer within proteins are significantly less complex than has been the
prevailing view.
http://www.med.upenn.edu/news/News_Releases/nov99/elec.shtml
*Crack open an egg and cure a disease. Two American companies are planning a
pilot test of drugs in eggs laid by genetically engineered chickens. The
birds carry genes that make their eggs contain proteins that can treat
disease. These proteins are then passed on to future generations of chickens
without the need to repeat the injection.
http://www.newscientist.co.uk/ns/19991113/newsstory5.html
*Improved biodegradable hydrogels. Two novel biodegradable hydrogels
developed by a Cornell University fiber scientists have potential
applications for controlling and delivering many kinds of medications inside
and outside the body, for anchoring biological substances such as skin and
vascular tissues and may even be used to introduce viruses to the body for
gene therapy.
http://www.news.cornell.edu/releases/Nov99/hydrogel.advances.ssl.html
*UNC-CH Physicists Find Atoms Of Chilled Metallic Liquids Chiefly Move In
Lockstep
CHAPEL HILL - For the first time, atomic-scale measurements have revealed
that atoms in a metallic liquid cooled significantly below the melting
point - also known as a super-cooled liquid -- chiefly move together in
clustered lockstep.
http://www.sciencedaily.com/releases/1999/11/991112070246.htm
*Lawmakers seek special labeling for genetically engineered food. Everybody
who eats food made in America deserves to know what's in it, a bipartisan
group of lawmakers said as they offered legislation to create special food
labels.
http://cnn.com/FOOD/news/9911/11/bioengineered.foods.ap/index.html
*Novel neurotransmitter overturns laws of biology, offers potential for
stroke treatment. Johns Hopkins scientists have identified a new and unusual
nerve transmitter in the brain, one that overturns certain long-cherished
laws about how nerve cells behave.
http://hopkins.med.jhu.edu/NewsMedia/press/1999/NOV99/991108.HTM
*Memory uses separate information pathways. The memory has separate pathways
for different types of information. This has been demonstrated by means of
anatomical and electrical measurements of the hippocampus and the adjacent
cerebral cortex of laboratory rats. The signal pathways ultimately meet in
the so-called subiculum of the brain, from which information from the
hippocampus is passed on to other areas of the brain.

*Cheap energy - a revolutionary new way. Australian scientists have
perfected a new-age combustion technology, which is poised to clean up
greenhouse gas emissions, slash energy costs and significantly boost
productivity."We have produced a new generation pulse combustion technology
which until now has defied the best efforts in the world to turn it into a
practical option for everyday use,"
http://www.csiro.au/page.asp?type=mediaRelease&id=PulseCombustor
*Optic fibre world records broken.Bell Laboratories believe they have broken
two world records in the use of optical fibres to transmit information.
http://news.bbc.co.uk/hi/english/sci/tech/newsid_517000/517733.stm
*Gene Skews Inheritance Patterns. Mouse geneticists have known for decades
that, contrary to the laws of Mendelian genetics, one member of certain
chromosome pairs may be passed to the next generation more often than the
other member. Now scientists have fingered the gene responsible for giving
some mouse chromosomes their advantage.
http://www.academicpress.com/inscight/11121999/grapha.htm
*Great minds share millennial visions. Thirty great minds offer their
visions for the 21st century in a new book titled “Predictions.
http://www.msnbc.com/news/331095.asp
*Irish Times Opinion. "Unseen power of simple microbe." The most common
image evoked by the term micro-organism(microbe) is likely to be that of
"germs", i.e. disease-causing microbes. Some micro-organisms do cause human
disease but to think of this entire class of biological organisms in this
manner is to grossly underestimate its importance and role.
http://www.ireland.com/newspaper/science/1999/1108/sci1.htm
*Taking Einstein to the Mat. Project Peers into Black Holes to Test Theory
of Relativity. Scientists gather this week in the piney woods of Louisiana.

*Easing the squeeze delivers diamonds. A new way of making artificial
diamond, reported in Nature1, may take the pressure off the
synthetic-diamond industry. The precious crystals are currently made by
squeezing graphite at pressures comparable to those in the deep Earth; the
new discovery offers a gentler way to make graphite’s sparkling sibling.
