Targeting treatment
The effectiveness of many potentially powerful treatments including drug therapy, gene therapy and cancer chemotherapy is often reduced because it can be difficult to target the treatment exactly where it will be most effective. One of the problems is that it is frequently difficult for drugs, as... view more (2002-03-26)

‘Labour onset’ device signals the end of false alarms
Scientists at Leeds University researching the relationship between electrical signals in the womb and the onset of labour have received funding to turn the idea of a labour prediction device into reality. Dr Nigel Simpson and Professor James Walker from the Department of Obstetrics and Gynaecology... view more (2000-11-07)

Circuit board materials may like it hot (or not)
Electrical circuits may act differently in Arizona than they do in Alaska—potentially affecting the performance of computers and other electronics. A new technique identifies and quantifies an important cause of this temperature sensitivity.   view more (2006-06-09)

Fragranced Candles Pack A Killer Punch
In recent years the consumer market for candles has grown dramatically, as candles of all shapes, sizes, colours and fragrances have been used increasingly in homes and restaurants to create atmosphere and enhance mood. Now two researchers at the University of Southampton have taken the potential... view more (2004-06-17)

Funding to develop tomorrow's technology
The University of Sussex is the only university to receive two awards from a new multi-million-pound government fund that aims to revolutionise scientific research and innovation. Two initiatives at Sussex are to be supported by the Basic Technology Research Programme, which is being managed by the... view more (2002-02-26)

Safe decay detector developed by dentists and textile experts
Tooth decay could soon be detected without resorting to potentially harmful X-rays - by using a novel electrical technique developed by dental researchers at the University of Dundee in an unusual partnership with textile experts at Heriot Watt University. Laboratory tests show the device, which... view more (2002-03-20)

Claudin 11 stops the leaks in neuronal myelin sheaths
Devaux and Gow demonstrate how a tight junction protein called claudin 11 makes the neuronal myelin sheath a snug fit.   view more (2008-12-01)

Rat kidneys and toad brains communicate in almost the same manner
Dutch researcher Niels Cornelisse used computer models to study the electrochemical communication between cells from rat kidneys and cells from the pituitary gland of a toad species. He found many similarities in the coupling of chemical and electrical signals in these completely different cells.   view more (2004-05-07)

Dartmouth researchers discover chromium's hidden magnetic talents
Two Dartmouth researchers have determined that the element chromium displays electrical properties of magnets in surprising ways.   view more (2008-04-17)

Electric fish conduct electric duets in aquatic courtship, Cornell neurobiologists discover
Cornell researchers have discovered that in the battle of the sexes, African electric fish couples not only use specific electrical signals to court but also engage in a sort of dueling "electric duet."   view more (2007-06-21)

New non-invasive sensor can detect brainwaves remotely
Scientists have developed a remarkable sensor that can record brainwaves without the need for electrodes to be inserted into the brain or even for them to be placed on the scalp. Conventional electroencephalograms (EEGs) monitor electrical activity in the brain with electrodes placed either on the... view more (2002-10-24)

New challenge for producers of refrigerators
The European Union has introduced a directive on waste electrical and electronic equipment (WEEE). The directive makes producers responsible for the recycling of the electrical and electronic equipment that they put on the market. The results from a study of refrigerators made by CIT Elektronik,... view more (2003-11-26)

Electrical conductivity of carbon nano-tubes

Novel salamander robot crawls its way up the evolutionary ladder
A group of European researchers has developed a spinal cord model of the salamander and implemented it in a novel amphibious salamander-like robot. The robot changes its speed and gait in response to simple electrical signals, suggesting that the distributed neural system in the spinal cord holds... view more (2007-03-09)

No increased risk of certain cancers from electromagnetic fields among energy workers
Electromagnetic fields do not pose a health hazard to workers in the electrical energy supply industry, suggests a large study of 28,000 people, published ahead of print in Occupational and Environmental Medicine.   view more (2007-05-01)

New technique measures chemical composition of tiny details
The method which the Eindhoven have developed is based on the radiation emitted by an object when it is irradiated by a beam of electrons. The measurable phenomenon occurs because the electrons in the beam collide with electrons in the atoms making up the object so that they enter an excited state.... view more (2000-01-18)

DNA’s oscillating double helix hinders electrical conduction
DNA has an oscillating double-helix structure. This oscillating means that the DNA molecules conduct electricity much less well than was previously thought. Ultrafast cameras were one of the devices the researchers from Amsterdam used to demonstrate this. It turns out the DNA does not have a rigid... view more (2002-09-11)

More brain research suggests
Queensland Brain Institute (QBI) scientists have found another important clue to why nerve cells die in neurodegenerative diseases, based on studies of the developing brain.   view more (2008-02-07)

Life at the jolt
Researchers at the Biodesign Institute are using the tiniest organisms on the planet 'bacteria' as a viable option to make electricity. In a new study featured in the journal Biotechnology and Bioengineering, lead author Andrew Kato Marcus and colleagues Cesar Torres and Bruce Rittmann have gained... view more (2008-01-03)

MPI researchers have for the first been able to map the activity of the brain by means of electrical microstimulation
