Robot Walks on Water
A new robot made of
ultralight carbon-fiber can
stand or slowly walk on
water. The principle it uses
is borrowed from insects --
surface tension tends to
prevent the water's surface
from breaking, and the

Liquid Body Armor
Rheologists have created a
new way of bullet-proofing
clothes using
shear-thickening fluids.
Fabric treated with
shear-thickening granular
suspensions can turn soft
material into solid

Breakthrough for Breathing
Doctors can now keep
patients who are in
respiratory care safer with
a new kind of ventilator.
Ventilator oxygen is
completely dry and needs to
be humidified for the

Testing Water
Playing a role once reserved
for environmental engineers,
children are now helping to
test the health of water in
their local communities. A
new kit comes equipped with
everything needed to test
the water's temperature, oxy ... > full story

Physical Chemists Devise Quick Spectrometry-Based Mercury Test
Physical chemists have created a new, cheap test to detect mercury, an element known to harm the brain, kidneys, heart, lungs and immune system. A gold nanorod absorbs mercury from a sample and, then ... > more -
Industrial Toxicologists Develop Cost-Effective, Life-Saving Disinfection
Industrial toxicologists at a non-profit venture founded by Procter & Gamble developed PUR, a water purifier that combines a flocculant -- which separates particles and organisms from water -- ... > more -
New Software Helps Track the Path of Toxic Spills
Ecological engineers have developed software that can model the path of a toxic spill in waterways anywhere in the United States. The system can predict if and when a contaminant will reach a ... > more -
The Science Behind Wave Pools
Scientists gives us a sneak peek into the world of wave pools, and explain how these huge pools make constant waves. Waves are made by a huge compressor that feeds four gigantic air blowers. Then a ... > more -
Materials Scientists Copy Beetle Anatomy To Develop New Coatings
Scientists at M.I.T. looking to add new chemical functionalities to spray coatings have turned to the beetle for inspiration. Some beetles that live in very arid climates get their drinking water by ... > more -
Acoustic Waves Could Help Put Out Flames in Zero-Gravity Environments
Aboard NASA's "Weightless Wonder" airplane, physicists are experimenting with combustion and fluid flows in zero-g and developing a fire extinguishing system based on sound waves. The technique could ... > more -
Atmospheric Chemists Show Morning Fog Captures Particulate Matter
While it hassles commuters, morning mist removes a lot of airborne particles which are hazardous for people with respiratory health problems. The water droplets inside morning fog are of just the ... > more -
Fluid Dynamics Class Inspires College Student To Develop 'Plasma Paddles'
As a kid, Stephen Taylor didn't just want to play video games ... he wanted to invent them too. Now, his dream is reality. Bored during a college break, he developed a video game called Plasma ... > more -
Food Chemists Find that Milk Pushes Air to Break Crystallized Sugar
Food scientists have discovered why Rice Krispies make their characteristic sound when soaked in milk. Rice Krispies contain lots of sugar and are cooked at high temperature, which makes the sugar ... > more -
Mathematical Physics Explains How Icicles Grow
When droplets of melted snow drip down an icicle, they release small amounts of heat as they freeze. Heated air travels upwards and helps slow down the growth of the icicle's top, while the tip is ... > more
