Taming High-Tech Particles. Cautious steps into the nanotech future.
Richard Smalley's lab at Rice University wrapped carbon nanotubes in
the polymer polyvinyl pyrrolidone (PVP). Scientists are seeking
water-soluble nanostructures for biomedical uses, such as drug
delivery. Yet making the nanostructures water soluble could permit
them to move easily though the environment. There is more to this
article. (Science News 3/30/02)

New MIT Nanomaterial Could Slide Into Future Soap And Beyond. A new
designer nanomaterial, created by Massachusetts Institute of
Technology researchers and described in the April 2 online edition of
the Proceedings of the National Academy of Sciences, acts like the
main ingredient in soaps, shampoos and detergents. This biological
substance may represent a big improvement over chemicals commonly
used in the multibillion-dollar detergent industry.

Spiders Put A New Spin On Nanotech Industry. It's spring and the
spiders are coming - on the big screen and in small tech. In Sony
Pictures' "Spider-Man," which will be released next month, geeky
Peter Parker gets bitten by a genetically altered spider and becomes
a superhero who can cling to any surface. The web slinger in the red
suit is science fiction, but not so far-fetched is the idea of using
spiders' handiwork as natural-world inspiration for how to make
better nanomaterials. (Small Times 4/2/02)

Nanocrystals' trapped atoms technology studied at Oak Ridge Labs. A
whole new technology awaits exploration with the discovery of a
technique for trapping single atoms, say scientists at the Department
of Energy's Oak Ridge National Laboratory (ORNL). ORNL's Mike Barnes,
Thomas Thundat and Adosh Mehta have collaborated with Ramesh Bhargava
of Nanocrystals Technology in Briarcliff, N.Y., to cage single
europium atoms in nanocrystals not much larger than the atoms
themselves.

Nanobots are not smart...yet. In a talk that was equal parts humor,
speculation and up-to-date research, the director of the University
of Southern California's Laboratory for Molecular Robotics discussed
the endless possibilities of nanoresearch. Citing health care as an
enormous area for applications of nanotechnology, Requicha predicted
a future in which our natural defenses are bolstered by technology.
"You might be able to detect pathogens very early and have millions
of these (man-made) organisms in your body happily replicating. You'd
never even know that you were about to get sick," he said.

Nanotubes self-assemble into circuit elements. Nanotubes measuring
just 100 atoms in diameter have been created from designer molecules
that were customized to self-assemble into angstrom-sized circuit
elements, according to researchers at Purdue University.
Professor Hicham Fenniri's research group developed the nanotube
"parent" molecules, which self-assemble in water first into tiny
rings...(3/26/02)

Nano-Tex Markets Brand To Become "Intel Inside" OF NANO MATERIALS.
Nano-Tex LLC has an unusual position in the nanomaterials industry.
It's not just its products, polymers engineered to attach to fibers
to make clothes stain-proof, wrinkle-free, absorbent or more
comfortable. Nor is it its worldwide business partnerships with
textile mills and fabric manufacturers. "We're trying to position
ourselves to be an ingredient brand, like Intel," said George
Henderson III, chief executive of Nano-Tex and the textile company
Burlington Industries, both based in Greensboro, N.C. Burlington owns
51 percent of Nano-Tex. (Small Times 3/23/02)

Magnetism to its lowest terms. While an ideal infinite chain of atoms
cannot sustain ferromagnetic order at nonzero temperature, an
international team of physicists shows that the finite length of the
chains and magnetic anisotropy barriers stabilize ferromagnetism at
finite temperatures in monatomic cobalt chains. The persistence of
ferromagnetism in monatomic chains has important consequences for the
design and properties of magnetic nanostructures, a very active field
of physical research and development today. (Max Planck Society

British Law Would Make Organ Donation Automatic Upon Death. People
should have their organs automatically removed for transplants after
they die unless they had expressed objections when alive, according
to a Bill to go before the Commons today. The 10-minute rule Bill,
supported by doctors' leaders, reaches MPs amid fears that people are
dying needlessly because of a shortage of donors. (Rense 3/21/02)

Mainstream Business, Government Interest Is Growing In Nano Research
And Investing. The next big thing to come out of this birthplace of
high tech could be small: Think tiny molecular delivery devices for
medicines. Or "smart" dust that can monitor people without being
detected. Maybe supercomputers the size of grains of salt. The
mind-bending ideas seem straight out of works of science fiction, but
some out here think they may be possible in the near future as
interest grows in something called nanotechnology. (Small Times

Bridgestone develops nanotech display. Japan's automobile tire maker
Bridgestone Corp. has developed a material that can be used to make
electric display panels consuming one-five hundredth the power of
conventional LCDs (liquid crystal displays), the company said
Wednesday. The new material, developed using nanotechnology, could be
used to make display panels which respond to moving images 100 times
faster than LCDs, for around half the cost, a Bridgestone spokesman
said. (IDG 3/20/02)

Scientist wires his nervous system to computer. A British robotics
scientist has wired up his nervous system to a computer in an
experiment he hopes will eventually give paralyzed people more
control over their own bodies. Kevin Warwick, professor of
cybernetics at Reading University in southern England, has had minute
sensors implanted in the main nerve in his left arm and hooked up to
a radio transceiver that will send and receive messages from a
computer. "We have a serious goal, a very medical goal of helping
people with spinal injuries and the like where there is a break in
the nervous system," Warwick told Reuters in a telephone interview.
"We will be sending signals from the nervous system to the computer
by radio and back the other way." (HoustonChronical 3/22/02)

Cool Carbon Foam New Material Leads to Cool Ideas. Feeling hot? One
day, a simple-looking block of solid foam could be the key to cooling
you - or anything else - down. Recently, researchers at the Oak
Ridge National Labs (ORNL) in Tennessee have developed a version of
carbon foam that acts as a super-conductor rather than an insulator
of heat. (ABCNews 3/22/02)

Self-configuring array enables atomic-scale fabrication. A
next-generation configurable circuit architecture is being proposed
by a group of designers at startup Cell Matrix Corp. The company is
building small prototype chips based on the concept. The architecture
goes beyond basic FPGAs by building arrays of "cells" rather than
simply re-configurable gates. Each cell has a small amount of logic
and local memory and communicates with its nearest neighbor. (EETimes

Lord of the Robots. The director of MIT's Artificial Intelligence Lab
says the age of smart, mobile machines is already beginning. You just
have to know where to find them - say, in oil wells. In the
not-too-distant future, a lot more people may be living with
technologies that Brooks's lab is developing. To help make pervasive
computing a reality, researchers in his lab and MIT's Laboratory for
Computer Science are developing - in an effort Brooks codirects
called Project Oxygen - the requisite embeddable and wearable
devices, interfaces and communications protocols. (TechReview 4/02)

Lab-grown fish chunks could feed astronauts. Cooking up ways to feed
explorers on long trips in space, scientists have coaxed chunks of
fish meat to grow in the laboratory. The technique could lead to the
production of copious amounts of protein for consumption without the
messy and involved business of killing fish or livestock. "This could
save you having to slaughter animals for food," said Morris
Bejaminson, a bioengineer and the leader of the NASA-funded project.

New lab is first at MIT to test tiny devices. A new NanoMechanical
Technology Laboratory at MIT will allow Institute researchers to
probe the mechanical properties of surfaces and devices at the atomic
and molecular scale. The laboratory "will have unique capabilities
for studying the properties of the tiny world," said Subra Suresh,
head of the Department of Materials Science and Engineering (DMSE).
For example, it will be home to the Institute's first nanoindenters,
machines that probe and measure the properties of surfaces of
engineering and biological materials. (MIT 3/15/02)

Present at the Creation. A Russian-Livermore collaboration has added
two new elements,
114 and 116, to the periodic table. Both have the comparatively long
lifetimes predicted by long-held superheavy element theory. The
Livermore researchers are continuing its work to explore the
southwest shores of the island of stability. With funding from the
Laboratory Directed Research and Development program, they have begun
efforts to add elements 115 and 113 to the periodic table. They are
in the process of sending 22 milligrams of pure americium-243 to
Dubna for the work on element 115. (Science and Technology Review

A New Form of Matter. Scientists have created a new kind of matter:
It comes in waves and bridges the gap between the everyday world of
humans and the micro-domain of quantum physics.It's not often that
you get to be around for the birth of a new kind of matter, but when
you do, the excitement is tremendous. "To see something which nobody
else has seen before is thrilling and deeply satisfying. Those are
the moments when you want to be a scientist," says Wolfgang Ketterle,
a physicist at MIT and one of the first scientists to create a new
kind of matter called Bose-Einstein condensates. (NASA 3/20/02)

Helium Nanoclusters Retain Full Magnetic Qualities. University of
Florida scientists report discovering a curious anomaly of magnetism
in an article that appears in the current edition of Physical Review
Letters. While "Novel Magnetism in He3 nano-Clusters" is a textbook

Science Close To Viewing The Beginning Of Time, University Of
Washington Cosmologist Says
When it comes to inflation, cosmologists are pondering a future that

UCLA Molecular Biologists Unravel Mysteries of 'Factory of Life'. In
their Nature paper, Lake and Simonson explain the molecular details
of elongation, including the location and movement of more than
10,000 atoms. In addition, they have located a novel binding site for
transfer RNA (tRNA) when it enters the ribosome. With the new
knowledge, it may become possible to make modifications in parts of
the translation process to suppress lethal mutations and design new
proteins to counteract the defects that cause numerous diseases, Lake
said. (UCLA news 3/21/02)

Scientists learning to manipulate carbon to achieve realistic
dreams.Even scientists, generally sticklers when it comes to detail,
have a hard time describing nanotechnology without speculation about
how it might be used years in the future.
Some of the visions of two decades ago - that tiny robots would cure
cancer and revive the dead - have given way to more realistic dreams.
But there are a lot of them, and they're still pretty darn good. All
make use of a natural ordering process called self-assembly.

The promise and perils of stem cell research. Since their discovery
20 years ago, stem cells have become one of medicine's great hopes,
and one of science's greatest political and ethical dilemmas. But
often lost underneath the arguments over the promise and peril of
stem cell research are nuances that don't fit with all the drama.
Despite a growing body of research, no one is sure whether these
cells, once taken out of the lab and turned into medical treatments,
will match expectations. (Mercury News 4/1/02)
