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.

Odorless Paint
December 01, 2007
Chemists have added polymers to a new paint that dries faster and requires no second coat or primer. The paint uses long polymer chains to surround pigments, which makes it easier for latex spheres to bond to it. That advance makes the color cover the wall more completely. Additionally, this technique means that the paint requires almost zero volatile organic compounds, which contribute to odor and also smog.

Creating 21st Century Video Games
November 01, 2007
A computer science student created an updated form of the classic video game Pong. The ball appears to move unpredictably, but is actually governed by algorithms that analyze the fluid dynamics of actual plasmas. Careful programming that considers the plasmaýs mathematical properties allows players to activate a vacuum effect or plasma jet that moves the ball in physically realistic ways as well.

Recycling Revolution
August 01, 2007
Chemical Engineers developed a way to break down plastic bottles made from polyethylene terephthalate -- or PET, and recycle it back into high value uses like more soda bottles, water bottles, beer bottles. Inside the recycling plant's extruder, water is removed from ground up plastic. Then, the plastic is melted and chemically broken down -- in a process called depolymerization. The breakthrough in this process is to be able to go from chips of this plastic to the recycled material in about five minutes.

Making Waves
August 01, 2007
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 computer controls chambers that generate the waves. When the chamber lids are closed, air from the blowers pushes the water out and makes a wave. When the valve is open, the balance tank fills with water, getting ready to make the next wave. It works just like a toddler pushing a cup upside-down onto water in a bathtub.

Mystery Diamonds
June 01, 2007
Carbonados, black carbon formations that resemble diamonds, have been show to have a chemical spectrum that indicates they originated before the formation of the Earth; their high hydrogen content suggests they are from a star-like environment. Since this carbon is only found in two locations on our planet, it may have arrived via an asteroid.

Man-Made Diamonds
March 01, 2007
New and improved technology has now made growing diamonds cost-competitive with mining them. Diamond-making machines subject a graphite-carbon core and a diamond seed at a pressure of 850,000 PSI for four days, recreating conditions similar to those 100 miles below the earth's surface. The lab-grown diamonds that come out are optically, chemically and physically identical to those that occur in nature.

Ice, Ice, Baby!
February 01, 2007
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 growing rapidly. Knowledge of the mathematical equations that govern icicle growth -- the same that apply to stalactites -- could help in the prevention of icicle formation on power lines.

Crime Alert! Molding Fingerprints
January 01, 2007
Photonic crystals -- materials with precise patterns of gaps that make them reflect only selected wavelengths of light -- could soon replace the traditional ink-based fingerprinting. In a new silica-based, photonic-crystal material, the spacing of the gaps changes in response to pressure applied. Corresponding changes in its color reveal fingerprints with high precision -- not only the ridges in the skin, but also the depth of the ridges, the shape of the finger, and the mechanical properties of the skin.

Rip Current Secrets Revealed
August 01, 2006
Rip currents flow in very erratic patterns, not in steady courses as previously believed -- which may help explain why they can be so dangerous even for experienced swimmers. Oceanographers have discovered the behavior by tracking the motion of colored dye added to a wave pool generating rip currents.

Liquid Body Armor
August 01, 2006
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 protective gear when struck by a projectile. The treatment can strengthen Kevlar to produce lighter, more comfortable bullet-proof vests, or it can be used to turn extend the bullet-proof protection to ordinary fabric.

The Mysterious Gravity Hill
June 01, 2006
At several hilly locations around the U.S., know as "gravity hills," objects such as cars left on neutral supposedly roll uphill, driven by unknown forces and against the force of gravity. Physicists say -- and GPS measurements confirm -- that the effects are illusions caused by the landscape. The position of trees and slopes of nearby scenery, or a curvy horizon line, can blend to trick the eye so that what looks uphill is actually downhill.

Einstein Rings
April 01, 2006
Images from the Hubble telescope reveal eight new Einstein rings, joining only three others previously known. Einstein rings are pairs of galaxies, with a foreground galaxy bending the light of a background galaxy into a ring by gravitational effects. The ring helps astronomers precisely estimate the mass of the foreground galaxy.

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.

Lights of the Future
February 01, 2006
Thanks to advances in physics, light-emitting diodes (LEDs) will soon move from traffic lights and electronics panels to home lighting, bringing dramatic energy savings, adjustable colors for ambiance, and light-shining furnishings.

Fog-Free Glass
January 01, 2006
When moisture condenses on a cool surface, droplets can form that are the right size to scatter light, fogging up glass. A new polymer coating draws droplets into nanopores and transforms them into a transparent sheet, improving vision.

Firefighting with Fog
January 01, 2006
Firefighters usually don't aim hydrants at smoke, to avoid producing steam that can come back and burn them. But smoke sometimes contains dangerous, flammable gases. Some U.S. fire departments are now experimenting with brief bursts of water on the hot gasses, to cool them down and reduce the risk of explosion. Since it was adopted in Sweden, the technique has cut firefighter fatalities in half.

The Mystery of Black Holes
December 01, 2005
A satellite called Swift is revealing that black holes have a messier birth than previously thought. Instead of being created in one instant, astrophysicists now believe after a star dies and collapses -- ultimately forming a black hole -- it continues to cause havoc. The baby black hole devours material while at the same time spewing it back out, a process that is revealed in multiple outbursts of gamma rays.

Unbreakable Glass
September 01, 2005
Sponges are the homes of colonies of tiny marine animals, and wonders of miniaturized engineering. They employ complex structural arrangements, the strongest glasses known to man, and even microscopic fiber optics that glow in the dark. Scientists are trying to figure how to reproduce some of their tricks, such as producing glass at low temperatures.

Flying and Radiation Risk
September 01, 2005
At the high altitudes and latitudes commercial airlines fly, crews are subjected to higher-than-normal radiation levels from the sun and cosmic rays. Physicist Robert Barish believes airline crew members are exposing themselves to more radiation than almost any other occupation and is calling for the airline industry to better educate workers about radiation.

Killing Germs
September 01, 2005
Preventing hospital infections -- from such stubborn bugs as Staphylococcus aureus -- could get a little easier with a new non-toxic, silver-based material. Used in coating, it helps keep hospital air ducts bacterium- and fungus-free. The material is also used in a number of products including athletic footwear, door hardware, pens and business supplies.

Sonic Golf Club
July 01, 2005
A new golf club uses motion-detection sensors and wireless technology to coach players through the use of sound.

Most golfers say they see improvements within 15 minutes.

Portrait of America
July 01, 2005
One lone physicist hopes to create an ultra-high-resolution portrait of America by taking a series of gigapixel images with his own custom camera, created from parts of old spy planes and nuclear reactors. Each image fills an entire DVD with data.

Screens of the Future
July 01, 2005
Organic Light-Emitting Diodes (OLEDs) are plastic-based materials that are able to emit light. Engineers are beginning to make displays out of OLEDs by spraying the materials on a surface, the way an ink-jet printer works. The new OLED displays promise to provide a cheaper, brighter, less power-hungry alternative to liquid-crystal displays -- the ones commonly used in laptop computers and cell phones.

New Combat Helmet
July 01, 2005
Wearing a helmet can make it hard to figure which direction sounds -- such as gunfire -- is coming from. Soldiers in Iraq are using a new helmet, called the Advanced Combat Helmet, which is padded internally to prevent sound from reverberating and masking its direction of origin.

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.

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.

Frostless Heat Pump
February 01, 2005
A new invention, the "frostless" heat pump, produces warmer air than a conventional heat pump by raising the temperature on the device's outer coils. This prevents frost on the coils while heat is suctioned more efficiently into the home.

Glass Bridges
February 01, 2005
To make bridges last longer and less expensive to maintain, engineers are working to incorporate glass into bridge design. Researchers say these longer-lasting glass-based bridges can withstand earthquakes better, and are faster to build, in addition to having high strength and durability.

Einstein At Home
February 01, 2005
In a new project called "Einstein@Home," members of the general public can use their computers' downtime to analyze data that physicists are collecting from space. The data searches for gravitational waves, ripples of gravity predicted by Einstein but never directly observed.

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.

Underwater Weather Watchers
January 01, 2005
Researchers are now collecting valuable information about ocean weather from a fleet of cost-effective instruments called Argo floats. Using hydraulic fluid in internal and external sacs, each float sinks about a mile and a half underwater. Every ten days, the float rises to the surface and transmits information on the ocean temperature and salt content. Researchers hope Argo will improve the ability to forecast the paths of hurricanes and where they will make their landfall.

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.

Samples From The Sun
January 01, 2004
A new NASA program called the Genesis Mission is launching a spacecraft to collect particles from the sun's solar wind to obtain information on the origin of earth and other bodies in the solar system.
