MIT, BU engineer cellular circuits that count events
MIT and Boston University engineers have designed cells that can count and "remember" cellular events, using simple circuits in which a series of genes are activated in a specific order. view more (2009-05-29)
Insulin signaling and amphetamines
Abuse of psychostimulants such as amphetamine remains a serious public health concern. Amphetamines mediate their behavioral effects by stimulating dopaminergic signaling throughout reward circuits of the brain. view more (2007-10-16)
Cells use 'noise' to make cell-fate decisions
Electrical noise, like the crackle heard on AM radio when lightning strikes nearby, is a nuisance that wreaks havoc on electronic devices. But within cells, a similar kind of biochemical "noise" is beneficial, helping cells transform from one state to another, according to a new study led by a UT Southwestern Medical Center researcher. view more (2007-03-23)
Autism problems explained in new research
New research from Melbourne's Howard Florey Institute helps to explain why children with autism spectrum disorders (autism) have problem-solving difficulties. view more (2005-10-25)
OSGi Communication Platform now in Automation
OSGi solutions (Open Gateway Services Initiative) are known as intelligent gateways within the areas of telecommunication, home networking and the automotive industry. Fraunhofer Institute for Integrated Circuits IIS now offers this standardized platform technology for control tasks in the field of automation technology. view more (2004-03-05)
Smaller microchips that consume less energy
To develop ever-smaller chips that consume less. These are the indispensable requirements of the current market for portable applications such as mobile telephone technology and biomedical systems, obtaining correct and trouble-free operation of the devices over the maximum possible duration of time. One of the techniques which, in fact, can be... view more... (2004-09-10)
CSHL links activity in brain synapses and developmental abnormalities with schizophrenia gene
Cold Spring Harbor Laboratory (CSHL) researchers have identified a function of neuregulin1 (NRG1), a gene previously linked to schizophrenia but whose role in the disease was unknown. view more (2007-05-25)
AN ELEMENT OF UNCERTAINTY
Professor Alan Murray and Dr Martin Reekie of the Department of Electronics & Electrical Engineering aim to develop small analogue circuits which will do what conventional computers find difficult - to represent the element of uncertainty which is present in most physical and biological processes and is an intrinsic feature of many natural... view more...

Brain plasticity: Changes and resets in homeostasis
In an article published in the June 25th edition of the journal Neuron, researchers at the Hotchkiss Brain Institute, University of Calgary, have found that synaptic plasticity, long implicated as a device for 'change' in the brain, may also be essential for stability. view more (2009-06-26)
UBC researchers put a new spin on electrons
In the first demonstration of its kind, researchers at the University of British Columbia have controlled the spin of electrons using a ballistic technique--bouncing electrons through a microscopic channel of precisely constructed, two-dimensional layer of semiconductor. view more (2009-04-16)
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)
Stanford study of owls finds link in brain between sight and sound
Just imagine listening to someone talk and also hearing the buzz of the overhead lights, the hum of your computer and the muffled conversation down the hallway. view more (2006-01-19)
Finding the constant in bacterial communication
The Rosetta Stone of bacterial communication may have been found. Although they have no sensory organs, bacteria can get a good idea about what's going on in their neighborhood and communicate with each other, mainly by secreting and taking in chemicals from their surrounding environment. view more (2009-07-07)
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)
Study suggests human visual system could make powerful computer
Since the idea of using DNA to create faster, smaller, and more powerful computers originated in 1994, scientists have been scrambling to develop successful ways to use genetic code for computation. view more (2008-07-24)
Molecular machines drive plasmonic nanoswitches
Plasmonics -- a possible replacement for current computing approaches -- may pave the way for the next generation of computers that operate faster and store more information than electronically-based systems and are smaller than optically-based systems, according to a Penn State engineer who has developed a plasmonic switch. view more (2009-02-12)
Analog and digital - hand in hand
Digital and high-frequency analog integrated circuits are manufactured using their own specific processes, leading `separate lives` in the past. Using standard CMOS, both types of component can now be integrated on a single chip - like a wireless transmitter device. view more (2002-02-01)
Scientists demonstrate method for integrating nanowire devices directly onto silicon
Applied scientists at Harvard University in collaboration with researchers from the German universities of Jena, Gottingen, and Bremen, have developed a new technique for fabricating nanowire photonic and electronic integrated circuits that may one day be suitable for high-volume commercial production. view more (2008-05-09)
Neurons hard wired to tell left from right
It's well known that the left and right sides of the brain differ in many animal species and this is thought to influence cognitive performance and social behaviour. For instance, in humans, the left half of the brain is concerned with language processing whereas the right side is better at comprehending musical melody. view more (2008-03-31)
Unlocking mystery of why dopamine freezes Parkinson's patients
Parkinson's disease and drug addiction are polar opposite diseases, but both depend upon dopamine in the brain. Parkinson's patients don't have enough of it; drug addicts get too much of it. Although the importance of dopamine in these disorders has been well known, the way it works has been a mystery. view more (2008-08-11)
