Spacecraft strikes Moon with intense flash

The SMART-1 lunar probe crashed into the Moon right on cue on Sunday morning. Mission controllers at the European Space Agency lost contact with the probe at 0542 GMT, indicating that it had struck close to the planned landing site on the lunar “Lake of Excellence”.

New type of Space propulsion

The xenon ion propulsion system, or XIPS (pronounced "zips"), is the culmination of nearly four decades of research into the use of electric propulsion as an alternative to conventional chemical propulsion. Available on the Boeing 601HP, or high power, and Boeing 702 satellite models, the increased efficiency possible with XIPS allows for a reduction in propellant mass of up to 90% for a satellite designed for 12 to 15 years operation. Less propellant results in reduced cost for launch, an increase in payload, or an increase in satellite lifetime, or any combination of the above.

An ion thruster (or ion drive), one of several types of spacecraft propulsion, uses beams of ions — electrically charged atoms or molecules— for propulsion. The precise method for accelerating the ions may vary, but all designs take advantage of the charge-to-mass ratio of ions to accelerate them to very high velocities using a high electric field. Ion thrusters are therefore able to achieve high specific impulse, reducing the amount of reaction mass required, but increasing the amount of power required compared to chemical rockets. Ion thrusters can deliver one order of magnitude greater propellant efficiency than traditional liquid fuel rocket engines, but are constrained to very low accelerations by the power/weight ratios of available power systems.
The first ion thrusters, known as Kaufman-type ion thrusters, were developed by Harold R. Kaufman, working for NASA in the 1960s, and were based on the Duoplasmatron.

Communicate and a non lethal weapon..

LRAD (Long Range Acoustic Device)
The Long Range Acoustic Device (LRAD™) is a breakthrough, highly-directional hailing and warning system designed to communicate with authority, affect behavior, and help determine intent up to 300 meters away. LRAD is a communication device that is:
LRAD offers the ability for:
Police to provide clear direction to gatherings and crowds
Officers to serve warrants from a safe distance.
Fire crews to communicate to potential victims in tall buildings or hard to reach areas.
Prison Guards to determine intent of groups and clearly control a riot without munitions
Maritime Vessels to clearly and forcefully communicate with small vessels that pose a threat.
Security Personnel to communicate in host nation language from a safe distance for checkpoint control
Airport Managers to scare away birds from roof tops and air fields with a directional transmission
Border Patrol Agents to clearly give warnings from helicopters to people on the ground with clarity over turbine noise
Hazardous Response Team Leaders to communicate with people in hazardous areas warning innocent bystanders to stay away in any language

Small robots called SwarmBots

SwarmBots communicate with their neighbors using a set-based neighbor query system and a gradient-based ad-hoc messaging system. Global behaviors are formed from the interactions of many individuals by using iRobot’s collection of "group behavior building blocks." iRobot developed a large library of these behaviors, and has used them to perform group tasks such as clustering to a location of interest, surrounding an object to measure its perimeter, navigating long distances using neighboring robots as landmarks, and exploring and mapping a large building.

Robotic military vehicle

Built on the rugged John Deere M-Gator™ platform and enhanced with proven iRobot and Deere robotic controls, navigation and obstacle avoidance systems, the R-Gator is designed to serve numerous important roles, acting as unmanned scout, "point man," perimeter guard, pack/ammo/supply carrier and more for soldiers, marines and airmen. In conjunction with John Deere, iRobot is producing a limited number of R-Gator prototypes in 2006.

Fighting CANCER with GENES

BBC Report shows 2 men cured of cancer
with astounding new treatment using gene technology...

How it works
Dr Stephen Rosenberg and his team isolated T cells from the cancer patients and multiplied them in the lab.

1 Blood taken from patient2 T cells infected with virus to carry key genes into them3 DNA from genes helps cells develop receptors4 Modified cells injected back into patient5 Receptors target cancerous cells to be killed
Next they used a virus to carry receptor genes into the T cells. These receptors are what enable the modified T cell to recognise specific cancers - in this case malignant melanoma.
When the modified T cells were transfused into the patients they began to attack the tumour cells.
For at least two months after the treatment, the modified cells made up at least 10% of the patients' circulating T cells.
The scientists are now looking at ways to enable greater numbers of the modified T cells to survive.
Dr Rosenberg said: "We've identified T cell receptors that will now recognise common cancers."

next US spaceship to take humans to the Moon.

The Lockheed Martin Corporation will build the next US spaceship to take humans to the Moon.
Nasa has awarded a multi-billion-dollar contract to the group to develop the Orion vehicle, which will replace the space shuttle when it retires in 2010.

I myself am astounded that this propulsion system is going to be used.
Seams like a waste of money to me in the award of this contract..
ancient technology at this point..
just my humble opinion of course.

Genetic Code for Organizing DNA Discovered.

In the July 20, 2006, journal Nature, scientists report cracking the genetic codethat determines where nucleosomes will be placed on the DNA strand. Those nucleosome proteins might be the key to curing diseases such as cancers linked to DNA mutations. Illustration created by Michael Ströck, 2006, Geophysics Fluid Dynamics Lab.

Human transporter

I wonder if there will be traffic jams on the sidewalks? :}

When Dean Kamen unveiled the Segway® Human Transporter (HT) on ABC's Good Morning America, he described the machine as "the world's first self-balancing human transporter." When you look at the machine in motion, you get an idea of what he's talking about. Unlike a car, the Segway only has two wheels—it looks something like an ordinary hand truck—yet it manages to stay upright by itself.
To move forward or backward on the Segway HT, the rider just leans slightly forward or backward. To turn left or right, the rider simply turns the steering grip left or right.
The ability to balance on its own is the most amazing thing about the Segway HT, and it is the key to its operation. To understand how this system works, it helps to consider Kamen's model for the device—the human body.
If you stand up and lean forward, so that you are out of balance, you probably won't fall on your face. Your brain knows you are out of balance, because fluid in your inner ear shifts, so it triggers you to put your leg forward and stop the fall. If you keep leaning forward, your brain will keep putting your legs forward to keep you upright. Instead of falling, you walk forward, one step at a time.
The Segway HT does pretty much the same thing, except it has wheels instead of legs, a motor instead of muscles, a collection of microprocessors instead of a brain and a set of sophisticated tilt sensors instead of an inner-ear balancing system. Like your brain, the Segway knows when you are leaning forward. To maintain balance, it turns the wheels at just the right speed, so you move forward. Segway calls this behavior dynamic stabilization and has patented the unique process that allows the Segway HT to balance on just two wheels.

Astronomers see far out on a budget :}

Astronomers used this inexpensive telescope to find an extrasolar planet transitingthe face of a Sun-like star 600 light-years from Earth. The telescope, which looks like a pair of binoculars,consists of two 200-millimeter telephoto camera lenses. The lenses are attached to electronic devices that measured slight dips in light output from the star, indicating that an object was crossing in front of it. The telescope is on the summit of the Haleakala volcano in Hawaii. Research team members are from theSpace Telescope Science Institute; Rice University; Boston University; University of Hawaii; University of Illinois; University of Florida; Boston University; Racoon Run Observatory; Hereford Arizona Observatory; CBA Belgium Observatory.
