*DNA computing a step closer. Biochemical computers that use DNA molecules
to store and process information are a step closer to reality thanks to a
technique demonstrated by American scientists this week. (Lab News 1/13/00

*Scientists Create RNA Computer. Princeton University researchers developed
a kind of computer that uses the biological molecule RNA to solve complex
problems. The achievement advances an emerging field in which scientists
harness molecules such as DNA and RNA to solve certain problems more
efficiently than could be done by conventional computing. (Scinews 1/15/00)

*The Problem With Plutonium. Scientists have long believed that solid
plutonium dioxide (PuO2), a compound used in nuclear reactors and warheads,
is the most stable form of plutonium. But in tomorrow's Science, a new
report shows that water can oxidize PuO2 and make it more soluble,
increasing the risk of leakage from storage facilities.

*US scientists 'clone' a rhesus monkey. In the latest edition of Science,
scientists from the Oregon Regional Primate Research Centre, report that the
monkey, called Tetra, was cloned using a method that splits the original
cells in an embryo to create multiple identical animals, a process described
as artificial twinning. (Lab news 1/14/00)

*Will Your Kids Live in a Floating City? Libertarians and other free
thinkers have long dreamt of a ship-board society, floating free, and free
from the constraints of society and government. With his Freedom Ship,
Norman Nixon is translating that dream into a reality. Read the article,
then vote in our survey! (Technocopia 12/13/99)

*Fire on a Spinning Disk. From bonfires to match sticks, flames usually have
simple, predictable shapes. But in the 17 January PRL a team describes a
completely unexpected burning pattern: spiral shaped flames on the surface
of a burning, spinning disk. Although spiral patterns have been seen in a
wide range of chemical and biological systems--including the burning of
premixed gases--no one had observed them amongst the complex flows of mixing
gases that occur when the fuel and oxygen molecules must diffuse to find one
another. (Physical Review Focus 1/12/00)

*New energy-efficient fume hood has potential to save hundreds of million of
dollars in energy costs. An advanced, energy-efficient laboratory fume hood
developed by scientists at Lawrence Berkeley National Laboratory is now
ready for field-testing. Fume hoods are ubiquitous in industrial, medical,
and research facilities. The new device has the potential to save some $300
million in annual U.S. energy costs.

*UNC-CH scientists create world's smallest pieces of ice. Using liquid
helium, chemists at the University of North Carolina at Chapel Hill have
succeeded in artificially creating the world's smallest pieces of ice.

*Two-Electron Prison Break. New experiments studying the cooperation among
electrons undergoing ionization show that electrons do not act alone when
intense light liberates two of them at once from helium and other rare-gas
atoms. When an intense light pulse removes more than one electron from an
atom, it's simplest to assume that electrons respond to the light
independently of their brethren and leave one by one. However, this
"independent electron model" fails by many orders of magnitude in predicting
double-ionization rates of atoms. (Physics News Update 1/12/00)

*New technique shows scalability of DNA computing. Scientists have taken DNA
computing from the free-floating world of the test tube and anchored it
securely to a surface of glass and gold. In so doing, they have taken a
small but important step forward in the quest to harness the vast potential
of DNA to perform the same tasks that now require silicon and miniature
electronic circuits. (University of Wisconsin 1/12/00)

*Beowulf Clusters Can Often Be A Faster Cheaper Option. A Penn State
engineering professor says low-cost personal computers linked to form
systems with supercomputer-like capabilities - popularly known as Beowulf
clusters - can be a faster, cheaper alternative for many chemists,
physicists, aeronautical engineers, electrical engineers and others who now
have to wait to use machines at national supercomputer centers.

*Artificial Vision System Helps Blind See. A New York researcher said on
Monday he had helped a blind man see again using electrodes implanted into
his brain and connected to a tiny television camera mounted on a pair of
glasses. (Yahoo !/17/00)

*Protect and survive. A genetic defect may trigger some miscarriages. If so,
can we prevent them?Millions of women may be susceptible to miscarriage or
having children with birth defects as a result of carrying genes for a
common enzyme deficiency, research on mice suggests. (New Scientist 1/15/00)

*Are We All From Mars? Comets and asteroids sent chunks of Mars spinning
into space - and some landed on Earth. Mars was more conducive to life long
before Earth, so maybe . Where, oh, where, did life originate? The answer
may not be as straightforward and obvious as you might think. (ABC news

*Mir may become space hotel. The mysterious $20m backer of the Mir space
station has come into the open and suggested that Mir would be used as a
space tourism destination. (BBC news 1/14/00)

*Book-preview with author: The mind: much more than matter. In his new book,
Antonio Damasio delves into the brain in search of the self. Here he
provides an exclusive preview. Contemplation of the mind may intimidate the
contemplator, especially when it comes to consciousness. Some believe an
explanation of its biological origins is unattainable. (Connected2)

*Chemical concerns-opinion. Transatlantic Traffic: North America and Europe
have taken turns the past decade to host the emergence of new environmental
and health debates that affect the chemical industry. It has become the
pattern that once an issue has surfaced on one side of the Atlantic, it
shows up on the other side within a year or so, whether it is through the
media or international environmental groups. (Chemical Week 1/9/00)

*Wielding the molecular scalpel. Physicists have used X-rays to execute
precise molecular surgery, cutting one chemical bond between atoms while
leaving others intact.
Whether you want to make a new drug molecule or destroy a toxic contaminant,
much of chemistry is a matter of atomic cut'n'paste. Chemists need ways of
selectively breaking apart the strong chemical bonds that bind atoms into
particular molecular configurations. but Now ........ (Nature Science update

*Biotech rice could solve major nutrition problem, scientists say. Its
yellowish color could be a turnoff, but a genetically engineered type of
rice could alleviate vitamin A deficiency in the developing world, a problem
that is a common cause of blindness in children, scientists say. Researchers
at a Swiss laboratory spliced three genes into the rice to make it rich in
beta carotene, the source of vitamin A, according to a report on their
findings appearing today in Science magazine. (Miami Herald 1/14/00)

*Exploring nuclear frontiers. Recent experiments using beams of radioactive
ions have shed new light on the structure of exotic nuclei at the very limit
of existence, and physicists are planning the next generation of
accelerators to stretch these boundaries even further. (Physics World

*Clothes connection. Call it the biggest advance since velcro: the
Electrical Snap Patch (right) from Autotime Corp. is a connector designed to
be inserted into clothing to attach and connect wearable computers, sensors,
display panels or keyboards to a host computer. The company believes the
connector will enable a new fashion line consisting of stereo coats and
jackets. (EE Times 1/14/00)

*Reproducing Robots. Fears about the planet's exploding number of human
beings have overshadowed the burgeoning population of another, more
benevolent 'species'. The world's population of robots nearly doubled over
the last decade. (Beyond2000 1/17/00)

30 nm processing (required for high-speed integrated circuit production
12-15 years from now)", says Professor Chris Wilkinson, Convenor of the
Nanoelectronics Research Centre based in the Department of Electronics and
Electrical Engineering.
