The new DocuPen from Planon System Solutions is a full-page scanner slightly bigger than a pen. It scans at 200-by-200 dots-per-inch resolution into 2 MB of on-board memory.
A robot race across the Mojave Desert turned into a parade of frustration Saturday, as 15 driverless vehicles spun their wheels, flipped over and encountered rocks and ruts that befuddled sensors and baffled programming.
Cal Tech astronomers may have discovered the solar system’s 10th planet, “Sedna,” more than 3 billion kilometers further away from the sun than Pluto.
The planet has a diameter of almost 2,000 km. The discovery will be presenting during a NASA briefing on Monday at 1:00 p.m. EST.
A trumpet-playing robot has been developed by Japanese car maker Toyota to showcase its prowess in humanoid robotics.
Toyota hopes to form a robot band to play at the 2005 World Exposition, being held in Aichi in central Japan.
A new method for producing uniform, self-assembled liposomes (a type of artifcial cell) has been developed by researchers at the National Institute of Standards and Technology (NIST). It may lead to an improved method for encapsulating drug therapies.
Current bulk methods for producing liposomes produce particles in a wide range of sizes, which must be sorted and filtered before being used for drug delivery, since dosage depends critically on… read more
USC/NASA-Ames have produced a nanowire-based memory cell with three different controllable bit states, for a total of 8 distinct levels, allowing for cramming more data into a fixed lateral region on a data storage device.
A scandal at the cadaver laboratory at the University of California, Los Angeles, has thrown back a heavy curtain that has kept trade in body parts largely hidden from public view.
The university suspended its Willed Body Program this week, and university police arrested the program’s director and a man the university accuses of trafficking in as many as 800 cadavers in a six-year body-parts-for-profit scheme.
A prototype disembodied robotic arm designed to move around the home has been unveiled.
The meter-long arm, called Flexibot, is capable of docking to a wheelchair or a wall and can help disabled people feed themselves and in other activities.
A thread of carbon nanotubes more than 100 meters long has been pulled from a furnace. The previous record holder was a mere 30 centimeters long.
By bundling the nanotubes together into much longer fibers, scientists hope to harness their properties on a larger scale. For example, embedding long carbon nanotube threads in plastic would allow tougher composites for airplane hulls.
Chipmakers should do more extensive nanotechnology research, right now, says Juri Matisoo, vice president of technology, Semiconductor Industry Association.
The SIA is predicting that today’s manufacturing techniques may stop finding advances some time around 2011.
Many scientists foresee revolutionary technologies based on the truly strange properties of the quantum world.
A robot for “printing” houses has been developed that takes instructions directly from an architect’s computerized drawings and then squirts successive layers of concrete on top of one other to build up vertical walls and domed roofs. The precision automaton could revolutionize building sites.
The first house will be built in 2005. If the technology is successful, the robot could enable new designs that cannot be built using conventional… read more
Scientists have witnessed an atom and a photon share the same information. This is an important milestone in the quest to create a quantum computer, which could operate much faster than conventional computers.
This is the first time that scientists have seen a single atom entangled with a single photon. These mobile bits of quantum information, known as “flying qubits,” have the potential to travel over many kilometers, eventually… read more
The next generation of Web search engines will do more than give you a longer list of search results. They will disrupt the information economy.
The search engines now under development are exploring methods for penetrating the terabytes of data hidden from search engines in databases — some 500 times more data than the surface Web.
Astronomers have taken the deepest look into the universe yet, at what could be the most distant galaxies ever seen.
The new image, called the Hubble Ultra Deep Field (HUDF), includes ancient galaxies that emerged just 700 million years after the Big Bang from what astronomers call the “dark ages” of the universe.
