Scientists moving closer to 'artificial noses'
These days, chemical analysts are expected to track down even single molecules. To do this highly sensitive detective work, nano researchers have developed minute strings that resonate in characteristic fashion. view more (2009-04-23)
Autonomous robot detects shrapnel
Bioengineers at Duke University have developed a laboratory robot that can successfully locate tiny pieces of metal within flesh and guide a needle to its exact location -- all without the need for human assistance. view more (2009-06-19)
Physicists tailor magnetic pairings in nanoscale semiconductors
Electrons love to zip around metals such as copper, especially if the metal is cooled to temperatures near absolute zero. But if they encounter a magnetic atom (say, iron) during their travels, the electrons will try to "screen," or cancel out, the magnetic atom's spin alignment by pairing with it. This pairing modifies the flow of... view more... (2007-03-15)
Nanotubes inspire new technique for healing broken bones
Scientists have shown for the first time that carbon nanotubes make an ideal scaffold for the growth of bone tissue. The new technique could change the way doctors treat broken bones, allowing them to simply inject a solution of nanotubes into a fracture to promote healing view more (2005-07-11)
Scientist of the University of Ghent discovers natural atom antihydrogen
On February 15, 2005 of the Physics/Einstein Year, the complete story of the discovery of natural atom antihydrogen, started in 1985, was published on-line. view more (2005-03-02)
ESF Task Force for Clean Solar Energy
The European Union and its member states are being urged by leading scientists to make a major multi million Euro commitment to solar driven production of environmentally clean electricity, hydrogen and other fuels, as the only sustainable long-term solution for global energy needs. view more (2006-06-13)
I'm listening -- conversations with computers
A computer system that can carry on a discussion with a human being by reacting to signals such as tone of voice and facial expression, is being developed by an international team including Queen's University Belfast. view more (2008-04-17)
¿Tiene la luz artificial el mismo efecto que la luz natural en el reloj biol'³gico?Un estudio realizado en roedores del sur del Sahara
El reloj biol'³gico interno es una estructura del sistema nervioso que regula las actividades fisiol'³gicas diarias (movilidad, sue'±o, nutrici'³n, etc.) y estacionales (hibernaci'³n, reproducci'³n, etc.) de los mam'feros. Est'¡ actualmente demostrado que el principal sincronizador del reloj interno es la alternancia d'a/noche en lo que se... view more... (1999-06-07)
Oxfordshire students take part in Science Fair at Rutherford Appleton Laboratory
On Friday 6 February 120 Key Stage 3 students from 20 Oxfordshire schools will be taking part in the County Science Fair at Rutherford Appleton Laboratory as part of the Oxfordshire Science Festival. This exciting event will feature a variety of activities - from egg races and game shows to a 'Crystal Maze' challenge based on some of the research... view more... (2004-02-04)
MIT paves way to 'artificial nose'
MIT biological engineers have found a way to mass-produce smell receptors in the laboratory, an advance that paves the way for "artificial noses" to be created and used in a variety of settings. view more (2008-09-30)
Biofeedback treats one type of chronic constipation
Chronic constipation affects 15 to 20 percent of the U.S. population. Nearly one-third of affected people have dyssynergic defecation, in which muscles used for bowel movements do not work well, but there's some good news. view more (2007-04-03)
UCR biologists unravel the genetic secrets of black widow spider silk
Biologists at the University of California, Riverside have identified the genes, and determined the DNA sequences, for two key proteins in the "dragline silk" of the black widow spider - an advance that may lead to a variety of new materials for industrial, medical and military uses. view more (2007-06-13)
Turning Sunlight into Liquid Fuels: Berkeley Lab Researchers Create a Nano-sized Photocatalyst for Artificial Photosynthesis
For millions of years, green plants have employed photosynthesis to capture energy from sunlight and convert it into electrochemical energy. A goal of scientists has been to develop an artificial version of photosynthesis that can be used to produce liquid fuels from carbon dioxide and water. view more (2009-03-11)
Researchers Learn Why Immune System's Watch Dogs Howl
Toll-like receptors are the guard dogs of the immune system, sniffing out bacteria and viruses then activating the body's immune system for an attack on these invaders. view more (2007-08-03)
Artificial cornea offers better results for infants, some blind patients
Infants and adults who are blind due to a cloudy or damaged cornea are seeing some remarkable results thanks to a new version of an artificial implant that takes the place of the cornea, the clear covering of the eye that serves as our window on the world. view more (2006-11-14)
Two More Potential HIV Vaccines
Despite long-term researchers' efforts, efficient human immunodeficienct virus (HIV) vaccine has not been created yet. However, researchers are not giving up their attempts. Russian biologists are now proposing two more vaccine options based on DNA that encodes human immunodeficienct virus proteins. Experience proves that traditional ways of... view more... (2004-05-17)
Intelligent property price forecasting system could help house buyers avoid overstretching themselves
House buyers could one day be able to consult a computer program to find out if any unforeseen changes in the economy might be lurking around the corner, leaving them with high mortgage repayments and a house worth less than they paid for it. Computer experts at the University of Glamorgan, with funding from the Swindon based Engineering and... view more... (2001-12-10)
Drinking water in Gaza Strip contaminated with high levels of nitrate
Palestinian and German scientists have recommended to the authorities in the Gaza Strip that they take immediate measures to combat excessive nitrate levels in the drinking water. view more (2008-08-15)
Your gut has taste receptors
Researchers in the Department of Neuroscience at Mount Sinai School of Medicine have identified taste receptors in the human intestines. view more (2007-08-21)
Language of a fly proves surprising
A group of researchers has developed a novel way to view the world through the eyes of a common fly and partially decode the insect's reactions to changes in the world around it. The research fundamentally alters earlier beliefs about how neural networks function and could provide the basis for intelligent computers that mimic biological processes. view more (2008-03-10)
