Dot Earth: Obama Pledges Allegiance to Science
President-elect Barack Obama pledged to embrace scientific advice, no matter how inconvenient.
Method Sorts Out Double-walled Carbon Nanotube Problem
It's hard to study something with any rigor if the subject can't be produced uniformly and efficiently. Researchers who study double-walled carbon nanotubes find themselves in just this predicament. The...
Argonne leadership computing facility makes it easy to be 'green'
From Deep Blue, the computer that defeated Garry Kasparov in a 1997 chess match, to the new Blue Gene(R) line of high-performance computers created by IBM, a single colour has...
Spinning Water Droplets Could Provide Insights into Black Holes, Atomic Nuclei
By magnetically levitating water droplets, and using a “liquid electric motor” technique to spin them, researchers can investigate how the droplets change shape. Rather than being just a curious experiment,...
Worlds first diamond laser built
Researchers have developed a way to make a laser using diamond, which could pave the way for powerful lasers in unusually high or low wavelengths.
Photographs show damage inside Cern's particle collider
Over the past few weeks, images from the underground tunnel that houses the giant particle accelerator at Cern in Geneva have appeared on scientific blogs, some
Tiny sensor detects cancer-causing toxins
U.S. scientists have developed a tiny sensor that can detect small amounts of cancer-causing toxins or trace the effectiveness of cancer drugs inside living cells.
Confusion, Not Decay, Most Important In Forgetting Over Short Term
Theories suggest that we forget when information simply decays from our memory (when too much time has passed) or when we confuse an item with other items that we have...
No Light at the End of the Test Tube
Charles Seife suggests it may be time to abandon the quest to produce nuclear fusion in the laboratory.
'Strained' Quantum Dots Show New Optical Properties
The first generation of quantum dots were made from the toxic heavy metal cadmium and had emission wavelengths, and colors, determined by their size. "Lattice strain" created by layers of...
Molecules in the spotlight
A novel x-ray technique allowing the observation of molecular motion on a time scale never reached before has been developed by a team of researchers from EPFL and the Paul...
Carbon Nanotube Clothing Could Take Charge in an Emergency [Slide Show]
A soldier is badly wounded on the battlefield in Afghanistan or Iraq by a roadside explosive. As he lies beside his vehicle, unable to reach his radio to contact his...
Researchers finger the cause of 'gravity fingers'
MIT researchers have found an elegant solution to a sticky scientific problem in basic fluid mechanics: Why water doesn't soak into soil at an even rate, but instead forms what...
'Impossible' Molecular Chain Reaction on Metal is Demonstrated
People said it couldn't be done, but researchers from the University of Pittsburgh and the U.S. Department of Energy National Energy Technology Laboratory (NETL) in Pittsburgh demonstrated a molecular chain...
Breakthrough experiment on high-temperature superconductors
(PhysOrg.com) -- New information about the metallic state from which high temperature superconductivity emerges, has been revealed in an innovative experiment performed at the University of Bristol.
Astrophysicists recreate stars in the lab
Astronomers are recruiting the physics laboratory to unravel the high energy processes involved in formation of stars and other critical processes within the universe. Experiments with high energy radiation and...
'Light within a light' offers CFL efficiency with incandescent bulb shape
(PhysOrg.com) -- In the coming weeks, General Electric will start selling a new "ship in a bottle" lightbulb - a fluorescent spiral bulb trapped inside a traditional incandescent-shaped bulb.
New Cloak of Plasma Found Around Earth
A detailed analysis of the measurements of five different satellites has revealed the existence of warm cloak of plasma around Earth.
