Antarctic Icebergs Help Ocean Take Up Carbon Dioxide

Antarctic Icebergs Help Ocean Take Up Carbon Dioxide The first comprehensive study of the biological effects of Antarctic icebergs shows that they fertilize the Southern Ocean, enhancing the growth of algae that take up carbon dioxide from the atmosphere and then, through marine food chains, transfer carbon into the deep sea. This process is detailed [...]

Physicists Create Quantum Twin Atoms

Physicists Create Quantum Twin Atoms Objects that are well separated in space but still cannot be understood separately belong to the profoundest mysteries of quantum physics. Pairs of photons are prominent examples of such systems. They allow the teleportation of quantum states or tap-proof data transfer using quantum cryptography. In future, such experiments will not [...]

Single Atom Stores Quantum Information

Single Atom Stores Quantum Information

Single Atom Stores Quantum Information A data memory can hardly be any smaller: researchers working with Gerhard Rempe at the Max Planck Institute of Quantum Optics in Garching have stored quantum information in a single atom. The researchers wrote the quantum state of single photons, i.e. particles of light, into a rubidium atom and read [...]

Fat Turns Into Soap in Sewers, Contributes to Overflows

Fat Turns Into Soap in Sewers, Contributes to Overflows Researchers from North Carolina State University have discovered how fat, oil and grease (FOG) can create hardened deposits in sewer lines: it turns into soap! The hardened deposits, which can look like stalactites, contribute to sewer overflows. “We found that FOG deposits in sewage collection systems [...]

New Biosensor Microchip Could Speed Up Drug Development

New Biosensor Microchip Could Speed Up Drug Development Stanford researchers have developed a new biosensor microchip that could significantly speed up the process of drug development. The microchips, packed with highly sensitive “nanosensors,” analyze how proteins bind to one another, a critical step for evaluating the effectiveness and possible side effects of a potential medication. [...]

Nanofiber Spheres Carrying Cells Injected Into Wounds to Grow Tissue

Nanofiber Spheres Carrying Cells Injected Into Wounds to Grow Tissue For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, but the cells live on to form new tissue. Developing this nanofiber sphere as a [...]

Sensor Determines If Packaged Meat Has Spoiled

Sensor Determines If Packaged Meat Has Spoiled When it comes to packaged fish or meat, it is nearly impossible to distinguish between fresh goods and their inedible counterparts. Researchers have now developed a sensor film that can be integrated into the package itself, where it takes over the role of quality control. And if the [...]

The Heat Is On: Zeroing in on Energy Consumption of Ice Makers

The Heat Is On: Zeroing in on Energy Consumption of Ice Makers In tests of four different types of new refrigerators, National Institute of Standards and Technology (NIST) researchers found that ice makers increased rated energy consumption by 12 to 20 percent. About three-fourths of that additional energy cost is due to the electric heaters [...]

DNA Nanoforms: Miniature Architectural Forms

DNA Nanoforms: Miniature Architectural Forms Miniature architectural forms — some no larger than viruses — have been constructed through a revolutionary technique known as DNA origami. Now, Hao Yan, Yan Liu and their colleagues at Arizona State University’s Biodesign Institute have expanded the capability of this method to construct arbitrary, two and three-dimensional shapes, mimicking [...]

Dark Matter Moves One Step Closer to Detecting Elusive Particle

Dark Matter Moves One Step Closer to Detecting Elusive Particle Dark matter, the mysterious substance that may account for nearly 25 percent of the universe, has so far evaded direct observation. But researchers from UCLA, Columbia University and other institutions participating in the international XENON collaboration say they are now closer than ever before. Their [...]
