Short bursts of high intensity
sprints--known to benefit muscle and
improve exercise performance--can
improve the function and structure
of blood vessels, in particular
arteries that deliver blood to our
muscles and heart, according to new
research from McMaster...

*************************
Astronomers from Johns Hopkins and
the SETI Institute plan to optimize
prospects of finding civilizations
on other star systems by
concentrating on the intersection of
the ecliptic plane (the imaginary
plane containing the Earth's orbit
around the Sun) and the galactic
plane (the Milky Way Galaxy band in
the sky), using the new Allen
Telescope...

displays make their debut
PhysOrg.com June 4, 2008
*************************
The EU-funded Coherent research
project has developed a 3-D display
called the HoloVizio. (Sergey
Drozdov/Dreamstime.com) The
HoloVizio is a 3-D screen that will
allow designers to visualize true
3-D models of objects, such as
models for the medical sector and a
collaborative design review system
for the automotive industry. Users
can...

Obituary: Lorenzo Odone
New Scientist news service June 4, 2008
*************************
Lorenzo Odone, who died last Friday
aged 30, was the subject of the film
Lorenzo's Oil, which made him the
most famous person to suffer from
adrenoleukodystrophy (ALD). ALD is
an inherited disease in which the
myelin sheaths around neurons are
destroyed. Without myelin, the
neurons cannot conduct signals
properly, causing brain damage and...

Giant telescopes could be built
from Moon dust
NewScientist news service June 4, 2008
*************************
Scientists at NASA's Goddard Space
Flight Center have created a
concrete-like substance using a
mixture of carbon nanotubes, epoxy
and a crushed rock material, and
built a 3-meter dish. Then they
added more liquid epoxy to its
surface and spun it, coating it with
aluminium in a vacuum. They believe
the process could be scaled up to
produce 20-...

Human stem cells used to cure brain
disorder
Nature news June 4, 2008
*************************
University of Rochester researchers
used human stem cells to correct
abnormal brain development in mice
with fatal brain disorders, caused
by missing myelin. The researchers
perfected a technique to implant
human glial progenitor cells (a type
of stem cell) into the nervous
system of mice. These stem cells are
able to differentiate into glial...

Mobile Robotic Arm Taught To
Manipulate Objects Such As Scissors
And Shears
Science Daily June 4, 2008
*************************
University of Massachusetts Amherst
researchers built a robotic arm that
can approach unfamiliar objects such
as scissors, garden shears, and
jointed wooden toys, and learn how
they work by pushing on them and
observing how they change. The arm
can "see" its environment through a
digital camera. After testing the
new object, the arm stores how...

Synthetic yeast to brew up vital
malaria drug
NewScientist.com news service June 4, 2008
*************************
Researchers at the University of
California, Berkeley, and colleagues
have added synthetic genes to yeast
to make a key malaria drug. The
genes encode enzymes that enable
sugar to be converted into a
precursor to artemisinin, used to
treat multi-drug resistant malaria.
This synthetic organism could be
producing enough artemisinin
precursor to...

Molecular brakes for nanotechnology
machines
Nanowerk Spotlight June 4, 2008
*************************
National Taiwan University
researchers and their colleagues
have designed a light-driven
molecular brake that could provide
on-demand stopping power for
nanotech machines. (American
Chemical Society) The brake
resembles a tiny four-bladed wheel
(a rigid pentiptycene group) and
contains light-sensitive molecules.
The paddle-like structure...

Carbon nanotube surface could help
regenerate cartilage
KurzweilAI.net June 5, 2008
*************************
Purdue University and Brown
University nanotechnology
researchers have found a way to
regenerate cartilage naturally by
creating a rough carbon nanotube
surface that attracts
cartilage-forming cells. Electrical
pulses applied to the cells then
encouraged them to grow. Current
methods to help with lost cartilage
involve injections of a synthetic...

The company XP Vehicles plans to
sell inflatable cars made with
"airbags"--the same polymer
materials used to cushion NASA's
rovers when they landed on Mars.
Different models of the car will be
made of various polymers, carbon
fiber, and other strong,
ultra-light-weight materials. They
claim its low weight will allow it
to have a range of 300...

Wireless sensor network keeps tabs
on the environment
KurzweilAI.net June 5, 2008
*************************
University of Alberta researchers
are building a wireless sensor
network that allows for clandestine
data collection of environmental
data in remote locations, with
monitoring from anywhere in the
world. The sensors can continuously
monitor data like temperature and
luminosity. They'll be deployed in
two locations--including a
rainforest--in...

Tongue stimulator can boost ailing
senses
NewScientist.com news service June 4, 2008
*************************
TIMC lab (Grenoble, France)
researchers have built a device that
relays body movements to an array of
electrodes on the tongue to help
people with balance or other
body-movement problems. The "sensory
substitution" allows people to sense
changes in their posture (or too
much pressure on a part of their
body) they can't otherwise feel, so

"Fantastic Voyage.... takes pains
to say: 'this is not a panacea, it's
just a beginning. You must make your
own path, keep up with research and
be a scientist.' This is a
refreshingly no-nonsense attitude,
and it's one of the main reasons
that I have a high degree of trust
and respect for the work that Ray
Kurzweil and Terry Grossman have
made available to us. -Mike T." To
