New ultrasensitive electronic sensor array speeds up DNA detection
A novel electronic sensor array for more rapid, accurate and cost-efficient testing of DNA for disease diagnosis and biological research has been developed by scientists at Singapore's Institute of Bioengineering and Nanotechnology (IBN). view more (2009-08-27)
Protein controls blood vessel formation, offers new drug target
After an injury, the body grows new blood vessels to repair damaged tissue. But sometimes too much growth causes problems, as when new blood vessels in the eyes leak, causing diabetic retinopathy and blindness if not treated. view more (2007-12-05)
Lipid plays big role in embryonic development
A little-known lipid plays a big role in helping us grow from a hollow sphere of stem cells into human beings, researchers have found. view more (2007-02-05)
Researchers link master regulator of innate immunity to the hypoxic response
Survival of all animals depends on their ability to withstand microbial infections and adapt to fluctuations in oxygen concentrations. view more (2008-04-24)
C1XS catches first glimpse of X-ray from the moon
The C1XS X-ray camera, jointly developed by the UK's STFC Rutherford Appleton Laboratory and the Indian Space Research Organisation (ISRO), has successfully detected its first X-ray signature from the Moon. view more (2009-01-26)
The Not-So-Digital Future of Digital Signal Processing
Fungi processing audio signals. E. Coli storing images. DNA acting as logic circuits. It's possible, and in some cases, it's already happened. In any event, performing digital signal processing using organic and chemical materials without electrical currents could be the wave of the future. view more (2008-04-08)
A round home robot aids the elderly
Rollo, the home robot, has been developed by the Laboratories of Automation Technology, Information and Computer Systems in Automation and Control Engineering of the Helsinki University of Technology for seven years and is presently being adapted for home care and independent living at home. Rollo is part of the "Turning Well-Being Technology... view more... (2002-05-03)
New 167-processor Chip Is Super-fast, Ultra Energy-efficient
A new, extremely energy-efficient processor chip that provides breakthrough speeds for a variety of computing tasks has been designed by a group at UC Davis. The chip, dubbed AsAP, is ultra-small, fully reprogrammable and highly configurable, so it can be widely adapted to a number of applications. view more (2009-04-22)
Cilia: small organelles, big decisions
Johns Hopkins researchers say they have figured out how human and all animal cells tune in to a key signal, one that literally transmits the instructions that shape their final bodies. view more (2007-10-04)
Monitoring of blood flow to the brain could prevent brain damage
University of Southampton engineers believe that monitoring blood flow to the brains of head injury patients could potentially reduce the incidence of brain damage and long-term disability, and are developing methods of using ultrasound to do this. With many years experience in studying the rise and fall of pressure inside the heads of patients... view more... (2003-04-30)
Chronic Alcohol Exposure Can Affect Brain Protein Expression
Researchers at the University at Buffalo studying the effects of alcohol on the brain, using zebrafish as a model, have identified several novel central nervous system proteins that are affected by chronic alcohol exposure. view more (2006-08-30)
UCSD Research May Lead to Targeted Treatment for Asthma Sufferers
The bronchial tubes of a patient with severe asthma can become scarred due to repeated episodes of allergic inflammation in the airways. The scarring results in blocked airways, excessive production of mucus, and shortness of breath. view more (2005-11-29)
Look out for giant triangles in space
THE search for extraterrestrial intelligence (SETI) could be taking the wrong approach. Instead of listening for alien radiobroadcasts, a better strategy maybe to look for giant structures placed in orbit around nearby stars by alien civilisations. view more (2005-04-06)
Scientists adopt fresh approach in quest for new therapies
Scientists are to pool their expertise in human health to pioneer an innovative approach to treating common diseases. view more (2007-11-27)
Drug resistance may travel same path as quorum sensing
The cellular "pumps" associated with multi-drug resistance in bacteria may also be involved in exporting signals responsible for cell-cell communication, a process known as quorum sensing. view more (2006-02-07)
Noise measurement may boost cell phone performance
Researchers at the National Institute of Standards and Technology (NIST) and industry collaborators have developed improved methods for accurately measuring very faint thermal "noise"—caused by random motion of electrons—in electronic circuits. view more (2006-06-28)
New advances in detection and identification technology from Oxford University
Increasingly, industry demands technologies that enable detection and identification of targets, ranging from information for traffic tolling and airspace management to patient supervision in hospitals, security passes and stock control. Researchers at Oxford University's Department of Engineering Science have developed new retroreflectors that... view more... (2002-07-01)
Racing neurons control whether we stop or go
In the children's game "red light green light," winners are able to stop, and take off running again, more quickly than their comrades. New research reveals that a similar race goes on in our brains, with impulse control being the big winner. view more (2007-04-19)
New hope for landmine detection
The first steps in a new method of detecting landmines by determining the presence of tiny quantities of the explosive TNT (trinitrotoluene) are described in research published today in the Institute of Physics publication Journal of Physics D. Markus Nolte, Alexei Privalov and Franz Fujara of Darmstadt Technical University in Germany, together... view more... (2002-04-15)
Scientists unlock secret of what makes plants flower
The study reveals the likely mechanism by which the Arabidopsis plant flowers in response to changes in day length. Earlier research had shown that plants' leaves perceived seasonal changes in day length, which triggers a long-distance signal to travel through the plant's vascular system from the leaf to the shoot apex, where flowering is induced. view more (2007-04-20)
