Tracking Cystic Fibrosis with Mice: DFG fellow develops an animal model for the disease
Cystic fibrosis, also known as mucoviscidosis, is one of the most common genetic diseases with a fatal outcome in western Europe. The disease is caused by a defective gene that affects the salt and fluid composition of respiratory tract secretions. As a result, they become highly viscous. The viscous mucous then clumps in the smaller lung... view more... (2004-04-26)
Thousands of cold anti-atoms produced at CERN
An international team of physicists working at the Antiproton Decelerator (AD) facility at CERN has announced the first controlled production of large numbers of antihydrogen atoms at low energies. After mixing cold clouds of trapped positrons and antiprotons - the antiparticles of the familiar electron and proton - under closely monitored... view more... (2002-09-18)
Where did Venus's water go?
Venus Express has made the first detection of an atmospheric loss process on Venus's day-side. Last year, the spacecraft revealed that most of the lost atmosphere escapes from the night-side. view more (2008-12-19)
Mystery of metallic glass is cracked by Johns Hopkins engineers
Using state-of-the-art lab techniques and powerful computer simulations, Johns Hopkins researchers have discovered how atoms pack themselves in unusual materials known as metallic glasses. view more (2006-01-27)
New evidence for organic compounds in deep space
The mysterious spectral bands in the infrared of interstellar gas clouds in deep space originate from organic compounds. Research by the Nijmegen physicist Hans Piest confirms this. He has provided new experimental evidence for this almost 30-year-old problem in astronomy. Each molecule has specific wavelengths at which it can either absorb or... view more... (2002-04-18)
Modified electron microscope identifies atoms
A new electron microscope recently installed in Cornell's Duffield Hall is enabling scientists for the first time to form images that uniquely identify individual atoms in a crystal and see how those atoms bond to one another. And in living color. view more (2008-02-22)
By color-coding atoms, new Cornell electron microscope promises big advance in materials analysis
A new electron microscope recently installed in Cornell's Duffield Hall is enabling scientists for the first time to form images that uniquely identify individual atoms in a crystal and see how those atoms bond to one another. And in living color. view more (2008-02-22)
Where is the proton? Yale scientists discover footprints of shared protons
This week in Science, Yale researchers present "roadmaps" showing that shared protons, a common loose link between two biological molecules, simply vibrate between the molecules as a local oscillator, rather than intimately entangling with the molecular vibrations of the attached molecules. view more (2007-04-13)
Rice ties in race for atomic-scale breakthrough
Everybody loves a race to the wire, even when the result is a tie. The great irony is the ultraprecise clocks that could result from this competition could probably break any tie. view more (2009-11-18)
New clues about a hydrogen fuel catalyst
To use hydrogen as a clean energy source, some engineers want to pack hydrogen into a larger molecule, rather than compressing the gas into a tank. view more (2009-08-05)
A first experiment with the new "free-electron laser"
An international group of scientists has published first experiments carried out using the new soft X-ray free-electron laser (FEL) at the research center DESY (Nature, vol 420, p 482-485 and p 467). Using small clusters of noble gas atoms, for the first time, researchers studied the interaction of matter with intense X-ray radiation from an FEL... view more... (2002-12-05)
Peering Inside Nanowires
Semiconductor nanowires - tiny wires with a diameter as small as a few billionths of a meter - hold promise for devices of the future, both in technology like light-emitting diodes and in new versions of transistors and circuits for next generation of electronics. view more (2009-04-02)
UCI scientists discover ozone-boosting chemical reaction
Burning of fossil fuels pumps chemicals into the air that react on surfaces such as buildings and roads to create photochemical smog-forming chlorine atoms, UC Irvine scientists report in a new study. view more (2009-07-21)
UCLA researchers clarify function of glucose transport molecule
Researchers at the David Geffen School of Medicine at UCLA have solved the structure of a class of proteins known as sodium glucose co-transporters (SGLTs), which pump glucose into cells. view more (2008-07-07)
Caffeic acid inhibits colitis in a mouse model -- is a drug-metabolizing gene crucial?
Researchers at Iowa State University have found that increased expression of a form of cytochrome P-450 (CYP4B1) is a key marker of inhibition of colitis in mice by caffeic acid, an anti-inflammatory antioxidant compound widely distributed in foods. view more (2009-05-27)
Hi ho silver! FSU physicist helps discover an atomic oddity
Working with an international team of scientists, a Florida State University physics professor has taken part in an experiment that resulted in the creation of a silver atom with exotic properties never before observed. view more (2006-01-30)
Uncharged organic molecule can bind negatively charged ions
Indiana University Bloomington chemists have designed an organic molecule that binds negatively charged ions, a feat they hope will lead to the development of a whole new molecular toolbox for biologists, chemists and medical researchers who want to remove chlorine, fluorine and other negatively charged ions from their solutions. view more (2008-02-27)
Light touch: Controlling the behavior of quantum dots
Researchers from the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (JQI), a collaborative center of the University of Maryland and NIST, have reported a new way to fine-tune the light coming from quantum dots by manipulating them with pairs of lasers. view more (2008-08-20)
Survey reveals British public don't know the difference between quarks and DNA - do you?
A survey commissioned by the Institute of Physics (IoP) has found that a staggering 98 percent of UK adults don't know what the world around us is made of. Just under two percent of those asked gave the right answer, quarks, the basic building blocks of all matter in the universe. The survey asked over 500 people what makes up the nucleus of an... view more... (2004-03-30)
Scientists Image 'Magnetic Semiconductors' On The Nanoscale
In a first-of-its-kind achievement, scientists at the University of Iowa, the University of Illinois at Urbana-Champaign and Princeton University have directly imaged the magnetic interactions between two magnetic atoms less than one nanometer apart (one billionth of a meter) and embedded in a semiconductor chip. view more (2006-07-27)
