October 17, 2011
A diode is an object that conducts electric current in only one direction. Powering a diode with an alternating current (AC) electric field causes the diode in this video to pump water over its surface, propelling it back and forth on the water surface. Modifying the AC field causes the diode to change direction.

Environmental scientists are evaluating the Gulf Stream as a source of renewable energy. Scientists are using sound to measure the speed and power of the current at different times. The hope is that one day, different types of energy-generating equipment could be stationed to turn the power of the ocean into electricity.
Robots in the Classroom
October 18, 2010
Learning to write can be challenging and even more frustrating when people can’t understand what you’ve written. Rehabilitation scientists designed a table-top robot to help kids improve their handwriting. A robotic arm, equipped with a pen, guides the user's hand through the movements of writing words repeatedly until the student can write legibly on their own.
Submerged In Oil
October 11, 2010
Physical oceanographers and geophysicists are using a robotic submarine to study the recent Gulf of Mexico oil spill in order to find how much oil is hidden beneath the surface. The submarine, a machine engineered to manipulate density and fitted with sensors to detect depth, location and methane levels traveled one mile below the surface and came within three miles of the spill, sampling the water for analysis.
Green Wheel For Eco-Cyclists
October 04, 2010
Architects and civil engineers designed a bicycle wheel equipped with a battery and motor to seamlessly replace the rear wheel of any standard bike. The battery allows one type of matter to convert into another, thus converting one form of energy into another and making each hill climb easier an easier.
Surviving the Storm
July 08, 2010
Emergency medicine physicians shared important lightning safety information, warning individuals, "When thunder roars, go indoors." The simple rhyme serves to help bystanders stay out of harm's way and avoid the neurological damage that results from being struck by lightning.
Lightning is a form of static electricity. We experience static electricity every time we drag our feet on the carpet and then touch a conducting surface, like a metal doorknob.
Cleaner, Greener Metals
June 10, 2010
Metallurgists created a cleaner and safer alternative to chrome that is equally durable, providing a solution to the environmentally harmful processes of both making chrome and disposing of it.
The new coating is made by dipping metal into a mix of nickel and tungsten atoms. An electrical pulse is sent through the mix, causing the atoms to adhere to the metal, or "plate" the surface. The electrical current is pulsed according to the pattern chosen by the researchers.
Life On Mars

Atmospheric scientists and physicists discover lightning on mars using a unique detector
Meet the Hexapod Robot
September 28, 2009
Matt Bunting is an Electrical Engineering student at the University of Arizona. He built his first robot when he was 11 years old. In this video he demonstrates his six legged robot known as a hexapod. He began building this hexapod when he was still in high school. It is controlled by a wireless Playstation controller with motion sensitivity.
Oh, and he also wrote the background music.
Robots Helping Stroke Survivors
July 03, 2009
Using fMRI in combination with a robotic device can help monitor the progress of stroke patients' rehabilitation.
Hearts In Danger
June 24, 2009
Medical physicists improved their ability to replace leads connecting pacemakers and defibrillators to the heart by using an excimer laser.
Reducing Your Lead Footprint
May 15, 2009
Materials scientists created a lead-free piezoelectric material to replace the current one used in electronics that contains up to 40 percent lead. To make the material tiny samples of bismuth ferrite and samarium ferrite are formed into puck shape pieces. A laser then fragments the pucks into different molecules and chemicals, creating a mist that is coated onto a chip.

Sniffing Out Bombs
July 01, 2008
A tiny sensor that monitors electrical conductivity allows scientists to detect the presence of explosives. The sensor measures the conductivity of two different thin films, one made of a cobalt compound and another made of a copper compound. When reacting to most fumes, the two films respond in similar ways, but when exposed to hydrogen peroxide the films show a difference in electrical conductivity. When the sensor indicates this difference, that means that trace amounts of hydrogen peroxide are present, a common ingredient of explosives.
Lightning: Fact or Fiction?
April 01, 2006
To study lightning, scientists use rockets connected to the ground by wires. They fire the rockets into clouds, triggering electrical discharges, and storing their power. They have found that lightning doesn't come straight down to the ground, but it instead takes a series of steps.
Sun Darkens Electronics
March 01, 2006
Solar activity can wreak havoc in communications systems -- particularly during coronal mass ejections, when plumes of electrically charged particles hit earth's atmosphere. Scientists can now track the plumes down to the single affected cities, helping to predict disruptions.
Inside the Brain
July 01, 2005
Children who have speech-impairing strokes often learn to talk again, while adult stroke victims can lose their verbal abilities for good. By giving reading and verbal tests inside the MRI, researchers are comparing the inner workings of both children's and adults' brains that suffered from strokes, as well as of healthy subjects'. The researchers hope to develop therapies to help the adult patients talk again.
Back Pain Relief
July 01, 2005
Up to 40 million American suffer from sciatica pains, but the condition is often not diagnosed correctly. A new imaging technique uses a specially tuned MRI scan to image nerves and highlight them deep inside tissues. Called Magnetic Resonance Neurography, the new technique promises to diagnose conditions such as sciatica -- in which a compressed nerve in the buttock causes persistent lower-back and leg pain -- in up to 95 percent of cases that were previously undiagnosed.
