Frozen Powder Drops
November 19, 2012
Water Droplets "freeze" into unique shapes when impacting a special powder at high velocities.
October 15, 2012
When falling onto another liquid layer, water droplets typically bounce then coalesce. If the surface is vibrating, however, the droplets will continue bouncing, as seen in this video.

Biologists and fly fishing experts explain the physics of the sport and the trick to the ideal cast.
Perfection on Ice
June 20, 2011
Biomechanists are helping ice skaters improve their performances, using motion capture technology to study skaters' movements.
Engineering For Earthquakes
May 16, 2011
Structural engineers designed a building foundation that can help to minimize damage when an earthquake strikes.
April 04, 2011
Engineers found that in certain areas of the basketball court, bank shots- which hit the backboard and fall into the net- can improve success by up to 20 percent, by using just a couple laws of physics.
New Approach to ACL Repair
March 07, 2011
Orthopedic surgeons are revolutionizing a traditional surgery that restores a vital component of the knee that helps keeps us stable on our feet, the anterior cruciate ligament. Traditional surgery can restore front-to-back stability in the knee, but the new surgery adds additional stability by creating a better fit for the repair- creating rotational stability and minimizing failure.
Girls Changing Science
February 14, 2011
Earth scientists, oceanographers and engineers worked with the youngest of scientists on real research contributing to real issues in today's world. Claire, only 9 years old, studied water runoff in her home town's grass soccer fields and compared it with runoff on turf fields. She found chemicals in both fields that sometimes exceeded levels set by the Government. In another project, a fourth grader named Olivia helped with a bio-inspired design for dropping emergency packs from great heights.
Forecasting Floods in 3D
October 25, 2010
Hydrologists at the USGS created a map that turns the weather forecast into a flood forecast in one hour. By adding the amount of approaching rain to the local geography and using physics equations, the flood map can show when and where a flood will occur and how deep the water will be to better prepare when storms hit.
New and Improved Wind Power
December 04, 2009
Mechanical engineers create wind turbine that responds to the wind, maximizes power generation.
Inside the Wind
November 20, 2009
Aerospace engineers use wind tunnel to study hurricane-strength winds.
Smart Bridge Keeping Drivers Safe
November 06, 2009
Civil engineers installed approximately 400 sensors in a bridge to monitor how corrosion, temperature and traffic loans impact the structure.
Science Behind Strikeouts
July 10, 2009
Kinesiologists use the principles of physics to explain why a fastball pitch in baseball is hard to hit and how a curveball gets its motion.

Electrical Engineers and Meteorologists Devise Method to Measure Strength of Lightning Strikes on Tall Buildings
Knowing Where Tornadoes Will Strike
August 01, 2008
Meteorologists recently studied the effect of gravity waves on tornado formation. They found that when gravity waves push down on rotating thunderstorms the storm compresses and spins faster. Being able to recognize and track gravity waves before they reach thunderclouds allows meteorologists to better predict tornadoes, increasing both the accuracy of their predictions and the amount of warning time that they can provide.
A Better Golf Game
January 01, 2005
Researchers have designed a golf ball that tends to fly straighter even when a putter unintentionally "slices" it which ordinarily causes it to curve to one side. The new ball has a hollow, metal core that shifts the ball's mass -- or weight -- to the outside. This helps the ball spin less and fly straighter as it sails through the air.
Surviving Hard Hits
January 01, 2005
Engineers have developed more protective padding for football players. Unlike traditional padding, the new putty-like material can be molded into protective gear to fit a player's body and better guard against injury. The squashy material redistributes the force from a hit evenly through the material to lessen the impact on a player's body.
