Nanowires can detect molecular signs of cancer, scientists find
Harvard University researchers have found that molecular markers indicating the presence of cancer in the body are readily detected in blood scanned by special arrays of silicon nanowires - even when these cancer markers constitute only one hundred-billionth of the protein present in a drop of blood. view more (2005-09-26)
Free smoke alarms to poor local authority households are a waste of time and money
Local authority schemes aimed at reducing fire-related injuries and deaths in poor urban households by providing and installing free smoke alarms could be a waste of time and money, according to a study carried out by researchers from the London School of Hygiene & Tropical Medicine. The study, the findings of which are published in today's... view more... (2002-10-31)
From food scraps to fuel cell
EMBARGOED UNTIL WEDNESDAY 9 OCTOBER 2002 19:00 BST UK CONTACT - Claire Bowles, New Scientist Press Office, London: Tel: +44(0)20 7331 2751 or email claire.bowles@rbi.co.uk SCRAPS of food could soon be helping power your home, thanks to an ultra-cheap bacteria-driven battery. Its developers hope that instead of feeding the dog or making garden... view more... (2002-10-09)

Fiber-based nanotechnology in clothing could harvest energy from physical movement
Nanotechnology researchers are developing the perfect complement to the power tie: a "power shirt" able to generate electricity to power small electronic devices for soldiers in the field, hikers and others whose physical motion could be harnessed and converted to electrical energy. view more (2008-02-14)
Limitless applications seen for micro-projector
A Finland-based company has unveiled ground-breaking optical technology allowing the manufacture of a matchbox-sized video projector. The results could be used in environments ranging from airplanes to nightclubs, living rooms to boardrooms, car dashboards to campsites. Billed as "the world's smallest colour video projector," this inexpensive... view more... (2004-06-03)
Construction materials for space stations
Antenna and telescope mirrors, walls and partitions for space stations, solar battery panels and even houses on the Moon and on Mars - all this can be achieved with technology developed by Russian scientists in the framework of ISTC projects 2835 and 2836. What is more, it can be achieved quickly, with good levels of strength and reliability, with... view more... (2005-03-03)
Workers exposed to lead show more cognitive problems later in life
Both the developing brain and the aging brain can suffer from lead exposure. For older people, a buildup of lead from earlier exposure may be enough to result in greater cognitive problems after age 55, according to a follow-up study of adults exposed to lead at work. view more (2009-01-12)
Hydrogen tank lighter than battery
Dutch-sponsored researcher Robin Gremaud has shown that an alloy of the metals magnesium, titanium and nickel is excellent at absorbing hydrogen. view more (2008-11-05)
Chemists measure copper levels in zinc oxide nanowires
Chemists at the National Institute of Standards and Technology (NIST) have been the first to measure significant amounts of copper incorporated into zinc oxide (ZnO) nanowires during fabrication. view more (2008-02-20)
Carbon nanotubes outperform copper nanowires as interconnects
Researchers at Rensselaer Polytechnic Institute have created a road map that brings academia and the semiconductor industry one step closer to realizing carbon nanotube interconnects, and alleviating the current bottleneck of information flow that is limiting the potential of computer chips in everything from personal computers to portable music... view more...
