Cells use 'noise' to make cell-fate decisions
Electrical noise, like the crackle heard on AM radio when lightning strikes nearby, is a nuisance that wreaks havoc on electronic devices. But within cells, a similar kind of biochemical "noise" is beneficial, helping cells transform from one state to another, according to a new study led... view more (2007-03-23)

Morphine kills pain — not patients
Many people, including health care workers, believe that morphine is a lethal drug that causes death when used to control pain for a patient who is dying. That is a misconception according to new research published in the latest issue of Palliative Medicine, from SAGE Publications.   view more (2007-03-22)

Advancing How Computers and Electronics Work
Researchers have made an important advance in the emerging field of 'spintronics' that may one day usher in a new generation of smaller, smarter, faster computers, sensors and other devices, according to findings reported in today's issue of the journal Nature Nanotechnology.   view more (2007-03-20)

Computer imaging assists with facial reconstructive surgery
A new calibration technique that involves measuring the distance between the upper ear and chin in photographs could help facial plastic surgeons use computer imaging software to achieve aesthetic harmony in their patients.   view more (2007-03-20)

Making sense of the world through a cochlear implant
Scientists at University College London and Imperial College London have shown how the brain makes sense of speech in a noisy environment, such as a pub or in a crowd. The research suggests that various regions of the brain work together to make sense of what it hears, but that when the speech is... view more (2007-03-13)

Chromium 6: A Killer Compound With An Improbable Trigger
Even miniscule amounts of chromium 6 can cause cancer. Blame that do-gooder nutrient, vitamin C.   view more (2007-03-13)

Smithsonian study concludes Caribbean extinctions occurred 2M years after apparent cause
Smithsonian scientists and colleagues report a new study that may shake up the way paleontologists think about how environmental change shapes life on Earth. The researchers summarized the environmental, ecological and evolutionary consequences for Caribbean shallow-water marine communities when... view more (2007-03-13)

Tracking sperm whales and jumbo squid
The sperm whale and its large prey, the jumbo squid, are among the deepest divers in the ocean, routinely reaching depths of 3,000 feet or more.   view more (2007-03-09)

New research finds that cholesterol busting statins also reduce blood pressure
A new study led by researchers at Warwick Medical School at the University of Warwick reveals that patients using cholesterol busting statins get a bonus benefit from such drugs as the Warwick researchers have now found that statins also have a positive effect on blood pressure levels.   view more (2007-03-09)

'Electronic gridlock' that blocks higher temperature cuprate superconductors is imaged by Cornell researchers
Superconductivity — the conduction of electricity with zero resistance — sometimes can, it seems, become stalled by a form of electronic "gridlock."   view more (2007-03-06)

Frozen lightning: NIST's new nanoelectronic switch
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a prototype nanoscale electronic switch that works like lightning—except for the speed.   view more (2007-03-05)

Quantum Effects Make the Difference
The atomic constituents of matter are never still, even at absolute zero (-273.15 degrees Celsius). This consequence of quantum mechanics can result in continuous transition between different material states. Physicists at the Max Planck Institute for Chemical Physics of Solids have studied this... view more (2007-03-05)

Delicate Relation between Single Spins
Probing the magnetic interaction between single atoms is no longer a dream. Using a scanning tunnelling microscope, the interaction of the spins of two neighbouring cobalt atoms adsorbed at a copper surface has been measured as a function of their distance with atomic precision.   view more (2007-03-05)

Improved predictions of warming-induced extinctions sought
In the March 2007 issue of BioScience, an international team of 19 researchers calls for better forecasting of the effects of global warming on extinction rates.   view more (2007-03-01)

New graphene transistor promises life after death of silicon chip
Researchers have used the world's thinnest material to create the world's smallest transistor - a breakthrough that could spark the development of a new type of super-fast computer chip.   view more (2007-03-01)

Manchester physicists pioneer new super-thin technology
Researchers have used the world's thinnest material to create a new type of technology, which could be used to make super-fast electronic components and speed up the development of drugs.   view more (2007-03-01)

Delft University of Technology designs language development toy for autistic children
Helma van Rijn has developed a toy that uses a new method for teaching words to autistic children. She developed this toy as part of her graduation project at Delft University of Technology's Faculty of Industrial Design Engineering.   view more (2007-02-28)

Childhood weight linked to proximity to green space and food stores
Living in greener neighborhoods or in closer proximity to grocery stores is associated with reduced risk of being overweight, according to a study of more than 7,000 children ages 3 to 18 conducted by researchers from the Indiana University School of Medicine; the Department of Geography, Indiana... view more (2007-02-26)

Under pressure, vanadium won't turn down the volume
Scientists at Carnegie's Geophysical Laboratory have discovered a new type of phase transition—a change from one form to another—in vanadium, a metal that is commonly added to steel to make it harder and more durable.   view more (2007-02-21)

Disorder may be in order for 'spintronic' devices
Physicists at JILA are using ultrashort pulses of laser light to reveal precisely why some electrons, like ballet dancers, hold their spin positions better than others—work that may help improve spintronic devices, which exploit the magnetism or "spin" of electrons in addition to or... view more (2007-02-16)

Study shows largest North America climate change in 65 million years
The largest climate change in central North America since the age of the dinosaurs 65 million years ago, a temperature drop of nearly 15 degrees Fahrenheit, is documented within the fossilized teeth of horses and other plant-eating mammals, a new study reveals.   view more (2007-02-08)

Concern over safety of commercial ultrasound scans
Expectant parent' desire to see images of their unborn children has given rise to commercial companies offering keepsake ultrasound scans without medical supervision, often referred to as "boutique ultrasonography."   view more (2007-02-06)

Microprinting Technique for Patterning Single Molecules
