Einstein Rings
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

Fighting Fire with Sound
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

Planes, Trains And Ant Hills
Financial analysts use the
concept of swarm
intelligence to solve
taxiway traffic problems at
airports. While ants
communicate via pheromones,
computer simulations use

The Mysterious Gravity Hill
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

Mathematicians Analyze Beer Bubbles To Peer Deeper Into The Structure Of Materials
Mathematicians built a formula to explain the behavior of beer bubbles in three dimensions and found that it can be applied to other materials like metals. Explaining the behavior of beer bubbles is ... > more -
Vision Researchers Test Theory on Visual Orientation
Vision researchers suspect that people who do not need maps to find their way may be remembering visual landmarks. To test this theory, the scientists are having volunteers navigate through a virtual ... > more -
Astrophysicists Discover New Details of How Stars Collapse
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 ... > more -
Mechanical and Aerospace Engineers Show Human Locomotion Optimizes Energy Use
Computer models of human locomotion are helping engineers understand why walk and run instead of hopping and skipping. The models are revealing that walking and running are the most energy-saving ... > more -
New Cast Skate Absorbs Impact, Distributes Weight, and Protects the Cast
Biomedical engineering principles helped an inventor create a boot that fits over a supportive cast, making it easier to walk without crutches. The device spreads the load over a larger area to ... > more -
Safer Ventilator Prevents Contamination From Water Condensation
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 patient's comfort, but water can ... > more -
Statisticians Show that High Altitude Makes Hits Longer
Two mathematicians at the University of Northern Colorado are taking a fresh statistical look at the effects of elevation on hitting -- specifically at Coors Field in Denver, where the field is at a ... > more -
Seismologists Use Ultrasounds to Assess Quakes Faster
Using ultrasound imaging, seismologists can now determine the epicenter and magnitude of an earthquake quake within 10 to 20 minutes, precisely imaging which fault ruptured and where the rupture ... > more -
Physicists Explain Tricky Skateboard Physics
Basic physics can explain how skateboarders are able to do those amazing tricks and why some are impossible. Newton's Laws of Motion explain everything from transferring energy through your body to ... > 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
