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

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

Virtual Reality for Navigation Skills
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

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 -
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 -
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 -
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 -
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 -

Computer scientists and engineers have developed a new technology for the purpose of seeing through walls. The new technological gadget boasts visual penetration through wood, plaster, brick and ... > more -
Physicist Calls for Airline Industry to Educate Workers about Radiation Levels
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 ... > 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 -
Applied Physicist Invents Training Golf Club with Audio Feedback
A new golf club uses motion-detection sensors and wireless technology to coach players through the use of sound. A golfer can "hear" the speed of the swing in wireless headphones, and adjust swings ... > more
