High-speed filter uses electrified nanostructures to purify water at low cost - 0 views

  •  
    Researchers have developed a water-purifying filter that makes the process more than 80,000 times faster than existing filters. The key is coating the filter fabric -- ordinary cotton -- with nanotubes and silver nanowires, then electrifying it. The filter uses very little power, has no moving parts and could be used throughout the developing world.

Moving holograms: From science fiction to reality - 0 views

  •  
    Scientists have developed a new type of holographic telepresence that allows the projection of a three-dimensional, moving image without the need for special eyewear such as 3-D glasses or other auxiliary devices. The technology is likely to take applications ranging from telemedicine, advertising,

The future of metabolic engineering: Designer molecules, cells and microorganisms - 0 views

  •  
    ScienceDaily (Dec. 3, 2010) - Will we one day design and create molecules, cells and microorganisms that produce specific chemical products from simple, readily-available, inexpensive starting materials? Will the synthetic organic chemistry now used to produce pharmaceutical drugs, plastics and a host of other products eventually be surpassed by metabolic engineering as the mainstay of our chemical industries? Yes, according to Jay Keasling, chemical engineer and one of the world's foremost practitioners of metabolic engineering.

Breakthrough chip technology lights path to exascale computing: Optical signals connect... - 0 views

  •  
    ScienceDaily (Dec. 3, 2010) - IBM scientists have unveiled a new chip technology that integrates electrical and optical devices on the same piece of silicon, enabling computer chips to communicate using pulses of light (instead of electrical signals), resulting in smaller, faster and more power-efficient chips than is possible with conventional technologies.

Invention regulates nerve cells electronically - 0 views

  •  
    ScienceDaily (May 22, 2010) - A major step toward being able to regulate nerve cells externally with the help of electronics has been taken by researchers at Linköping University and the Karolinska Institute in Sweden. The breakthrough is based on an ion transistor of plastic that can transport ions and charged biomolecules and thereby address and regulate cells.

Secondhand television exposure linked to eating disorders - 0 views

  •  
    ScienceDaily (Jan. 6, 2011) - For parents wanting to reduce the negative influence of TV on their children, the first step is normally to switch off the television set. But a new study suggests that might not be enough. It turns out indirect media exposure, i.e., having friends who watch a lot of TV, might be even more damaging to a teenager's body image.

Personalized medicine comes within reach - 0 views

  •  
    ScienceDaily (Feb. 18, 2011) - A team of biologists, clinical oncologists, pathologists and information scientists has established a strategy for identifying biomarkers. If a particular pattern of these biomarkers can be detected in the blood, this indicates a cancerous disease. An interdisciplinary research breakthrough that opens many doors.

In a genetic research first, researchers turn zebrafish genes off and on - 0 views

  •  
    ScienceDaily (May 9, 2011) - Mayo Clinic researchers have designed a new tool for identifying protein function from genetic code. A team led by Stephen Ekker, Ph.D., succeeded in switching individual genes off and on in zebrafish, then observing embryonic and juvenile development. The study appears in the journal Nature Methods.

Why some genes are silenced: Researchers find clue as to how notes are played on the 'g... - 0 views

  •  
    ScienceDaily (May 13, 2011) - Japanese and U.S. scientists in the young field of epigenetics have reported a rationale as to how specific genes are silenced and others are not. Because this effect can be reversed, it may be possible to devise therapies for cancer and other diseases using this information.

DNA can discern between two quantum states, research shows - 0 views

  •  
    ScienceDaily (June 4, 2011) - Do the principles of quantum mechanics apply to biological systems? Until now, says Prof. Ron Naaman of the Institute's Chemical Physics Department (Faculty of Chemistry), both biologists and physicists have considered quantum systems and biological molecules to be like apples and oranges. But research he conducted together with scientists in Germany, which appeared recently in Science, shows that a biological molecule -- DNA -- can discern between quantum states known as spin.

Historic first images of rod photoreceptors in the living human eye - 0 views

  •  
    ScienceDaily (June 9, 2011) - Scientists have just reported that the tiny light-sensing cells known as rods have been clearly and directly imaged in the living eye for the first time. Using adaptive optics (AO), the same technology astronomers use to study distant stars and galaxies, scientists can see through the murky distortion of the outer eye, revealing the eye's cellular structure with unprecedented detail. This innovation, described in two papers in the Optical Society's (OSA) open access journal Biomedical Optics Express, will help doctors diagnose degenerative eye disorders sooner, leading to quicker intervention and more effective treatments.
