Unplugged: Goodbye cables, hello energy beams

February 8, 2010

Wireless power transmission, resonant magnetic coupling, and infrared lasers are three methods of charging home appliances currently being researched, but safety concerns have been voiced.

Unnatural selection: Robots start to evolve

February 5, 2009

Researchers at Robert Gordon University in Aberdeen, UK have created a robot that adapts to such changes by mimicking biological evolution, using an incremental evolutionary algorithm (IEA) capable of adding new parts to its robot brain over time.

The robot is controlled by a neural network that can be trained. For example, if the goal is to remain balanced and the robot receives inputs from sensors that it is… read more

Unnatural Selection

January 28, 2005

Evolutionary algorithms, also known as genetic algorithms, are proving useful for solving complex problems, such as antenna design, and even creating inventions.

In the sci-fi thriller movie Paycheck, an engineer has his memory erased after completing a sensitive reverse-engineering job. Scientific American.com spoke with a leading neurobiologist to find out just how close scientists are to controlling recall.

Unlocking the Paralysis Riddle

October 25, 2001

Researchers studying spinal cord injuries have observed certain patterns of the human brain that may ultimately enable paraplegics and quadriplegics to regain some motor activity in their paralyzed limbs — or use their brains to control robotic limbs.

Researchers took MRI snapshots of the brains of quadriplegics as they were asked to move their hands, elbows, feet, knees and lips. The images revealed neural activity in all the places… read more

Unlocking The Matrix

May 12, 2003

TIME offers “an exclusive look at the year’s most avidly anticipated film epic.”

Unlocking the Brain’s Secrets

August 1, 2003

An international team of six scientists has been involved in scanning thousands of images of the brains of people of all ages with a range of conditions, in the hopes of creating a “map” that would reveal the mysteries of how the brain controls everything from language to movement.

Unleash your inner Asimov

Writing science-fiction stories about encounters with imaginary worlds and futuristic devices could have a decisive influence on innovation, G. Pascal Zachary, writer and professor at Arizona State University, suggests in IEEE Spectrum.

David Brian Johnson, Intel’s staff futurist, even insists in a recent book, Science Fiction Prototyping, that by writing stories about future products, engineers can do a better job of actually making them, he… read more

Unknown molecule opens the door to quantum computing

June 30, 2008

Purdue University researchers have have created a new hybrid molecule in which its quantum state can be intentionally manipulated. The discovery could allow for quantum computing in semiconductors in the future.

University to Investigate Fusion Study

March 8, 2006

Purdue University has opened an investigation into “extremely serious” concerns regarding the research of a professor who said he had produced nuclear fusion in a tabletop experiment.

The vibrations, they said, collapsed tiny gas bubbles in the liquid, heating them to millions of degrees, hot enough to initiate fusion. If true, the phenomenon, often called sonofusion or bubble fusion, could have far-reaching applications, including the generation of energy.… read more

University of Saskatchewan researchers discover cannabis ‘pharma factory’

University of Saskatchewan researchers have discovered the chemical pathway that Cannabis sativa uses to create bioactive compounds called cannabinoids, paving the way for the development of marijuana varieties to produce pharmaceuticals or cannabinoid-free industrial hemp.

U of S adjunct professor of biology Jon Page explains that the pathway is an unusual one, involving a specialized version of one enzyme, called hexanoyl-CoA synthetase, and another enzyme,… read more

University Of Michigan Launches Ambitious Exploration Of Inner Space

February 26, 2003

University of Michigan researchers will attempt to capture never-before-seen views of the chemical activity inside living cells in real time and 3-D.

The team will be using synthetic nanoprobes small enough to fit inside a cell without interrupting its normal functions to measure the activity of crucial metal ions like zinc and copper as the cell works. Sophisticated statistical modeling programs will be used to interpret the data.… read more

University of Miami engineer designs stretchable electronics with a twist

January 26, 2009

Researchers at three universities have developed a new design for stretchable electronics that can be wrapped around complex shapes, without a reduction in electronic function.

Potential uses for the new design include electronic devices for eye cameras, smart surgical gloves, body parts, airplane wings, back planes for liquid crystal displays and biomedical devices.

University of Maryland completes most extensive full-face transplant to date

March 28, 2012

The University of Maryland Medical Center has performed the most extensive full-face transplant completed to date, including teeth, both jaws, and tongue.

The face transplant, formally called a vascularized composite allograft (VCA), was part of a 72-hour marathon of transplant activity.

The face transplant team was led by Eduardo D. Rodriguez, M.D., D.D.S., associate professor of surgery at the University of Maryland School… read more

University of Denmark Scientists Develop Hydrogen Tablet

September 23, 2005

Scientists at the Technical University of Denmark have invented a technology which may be an important step towards the hydrogen economy: a hydrogen tablet that effectively stores hydrogen in an inexpensive and safe material in solid form: in ammonia absorbed efficiently in sea salt.
