Experts say cellphones are 'possibly carcinogenic'
(AP) -- A respected international panel of scientists says cellphones are possible cancer-causing agents, putting them in the same category as the pesticide DDT, gasoline engine exhaust and coffee.
How do cell phones affect young brains?
Cell phone safety warnings are generally designed for a large man with a big head who talks less than half an hour a day.
New approach to invisibility cloaking gets much closer to the science-fiction version
The idea of being able to become invisible, especially by simply covering up a person or an object with a special cloak, has a perennial appeal in science-fiction and fantasy literature. In recent years, researchers ...
Astrophysicists discover new galaxy clusters revealed by cosmic 'shadows'
An international team of scientists led by Rutgers University astrophysicists have discovered 10 new massive galaxy clusters from a large, uniform survey of the southern sky. The survey was conducted using ...
NIST ships first programmable AC/DC 10-volt standard
Extending its 26-year tradition of innovative quantum voltage standards, researchers at the National Institute of Standards and Technology (NIST) have begun shipping a new 10-volt standard to users around ...
Ripples in the cosmic background
(PhysOrg.com) -- The universe was created 13.73 billion years ago in a blaze of light -- the big bang. We also think that, about 380,000 years later, after matter (mostly hydrogen atoms) had cooled enough ...
New radiation mechanism may ward off cancer, oil spills and terrorism
Radiation similar to that used to treat cancer may someday help clean up environmental disasters such as the Gulf oil spill and detect explosive powder hidden underneath clothing.
Planck satellite unveils the Universe -- now and then (w/ Video)
(PhysOrg.com) -- ESA's Planck mission has delivered its first all-sky image. It not only provides new insight into the way stars and galaxies form but also tells us how the Universe itself came to life after ...
SMOS shines at symposium
Today, a focus at ESA's Living Planet Symposium is on the innovative SMOS mission, which recently became operational. Early results are proving very encouraging with its first observations due to be released in early July.
Americans get most radiation from medical scans
(AP) -- We fret about airport scanners, power lines, cell phones and even microwaves. It's true that we get too much radiation. But it's not from those sources - it's from too many medical tests.
Scientists create artificial mini 'black hole'
Probing the dark side of the universe
Advancing into the next frontier in astrophysics and cosmology depends on our ability to detect the presence of a particular type of wave in space, a primordial gravitational wave. Much like ripples moving ...
NASA to Probe the Universe's First Moments
(PhysOrg.com) -- Sophisticated new technologies created by NASA and university scientists are enabling them to build an instrument designed to probe the first moments of the universe's existence.
