UB Engineers Prove That Carbon Nanotubes Are Superior to Metals for Electronics
In the quest to pack ever-smaller electronic devices more densely with integrated circuits, nanotechnology researchers keep running up against some unpleasant truths: higher current density induces electromigration and thermomigration, phenomena that damage metal conductors and produce heat, which leads to premature failure of devices. view more (2009-03-23)
Improving the management of head and neck cancers
Cancers of the head and neck cause over 2,700 deaths per year in England and Wales. Smoking and drinking cause most cancers of the mouth, lip and tongue (oral cavity), throat and voice box. Heavy drinkers who are also heavy smokers have over 35 times the risk of developing oral cancer than non-smokers and drinkers. Early detection and appropriate... view more... (2004-11-22)
Under pressure, atoms make unlikely alloys
Ever since the Bronze Age, humans have experimented with combining different metals to create alloys with properties superior to either metal alone. view more (2009-03-11)
Between water and rock -- a new science
Water chemistry and mineralogy are scientific fields that have been around long enough to develop extensive knowledge and technologies. The boundary of water and rock, however, is not a thin wet line but the huge new field of nanoparticle science. view more (2007-12-03)
UK Study Underlines Safety Of Contraceptive Pill For Non-smokers (p 185)
Latest findings from a UK study established 35 years ago to assess the health outcomes for women using the contraceptive pill during the 1970s and 1980s are published in this week's issue of THE LANCET. The key finding from the study highlights no increased risk of death from any cause (except cervical cancer) for non-smoking pill users; however... view more... (2003-07-16)
"Nanominerals" Influence Earth Systems from Ocean to Atmosphere to Biosphere
The ubiquity of tiny particles of minerals--mineral nanoparticles--in oceans and rivers, atmosphere and soils, and in living cells are providing scientists with new ways of understanding Earth's workings. Our planet's physical, chemical, and biological processes are influenced or driven by the properties of these minerals. view more (2008-03-24)
Renaturation of waterbodies does not have to be expensive
The water landscape in many countries has many deficiencies. The ecological consequences of this are poor water quality as well as a deterioration and a shift of the naturally occurring species spectrum. The Fraunhofer Institute for Systems and Innovation Research ISI, Germany, has examined the existing morphological water structure deficiencies... view more... (2002-08-20)
Parking spaces outnumber drivers 3-to-1, drive pollution and warming
From suburban driveways to the sprawling lots that spring up around big retailers, Americans devote lots of space to parking spaces - a growing land-use trend that plays a role in heating up urban areas and adding to water pollution, according to a recent study. view more (2007-09-12)
Katrina floodwaters not as toxic to humans as previously thought, study says
The floodwaters that inundated New Orleans immediately following Hurricane Katrina were similar in content to the city's normal storm water and were not as toxic as previously thought. view more (2005-10-12)
BSE - A Post Industrial Disease?
Ahead of the Commons debate on BSE due to be held next week, an alternative hypothesis about the origin and behaviour of BSE and vCJD is posed in the latest issue of the SCI publication Chemistry & Industry. Dr David Brown of the University of Cambridge suggests that prion diseases are ‘post-industrial phenomena that will spread in... view more... (2001-02-13)
Nickel isotope may be methane producing microbe biomarker
Nickel, an important trace nutrient for the single cell organisms that produce methane, may be a useful isotopic marker to pinpoint the past origins of these methanogenic microbes, according to Penn State and University of Bristol, UK, researchers. view more (2009-06-23)
Researching neglected fields of science
Independent scientist Brian J Ford will undertake interdisciplinary scientific research in neglected fields thanks to a £75,000 Fellowship from NESTA (the National Endowment for Science, Technology and the Arts), the organisation that invests in UK creativity and innovation. Brian, from Eastrea in Cambridgeshire, has an international... view more... (2004-05-10)
Pioneering University Research Reveals Impact Of Newbury Bypass On The Environment
A three-year study by researchers from the University of Surrey, led by Dr Neil Ward, has revealed that although pollution from the Newbury Bypass in Berkshire has been minimised due to an effective design and higher construction standards, ongoing monitoring and maintenance is crucial in order to protect the environment. The nine-mile bypass,... view more... (2001-02-09)
Mystery solved: Gold's power against autoimmune diseases defined
Gold compounds have been used for the treatment of rheumatoid arthritis and other autoimmune diseases for more than 75 years, but until now, how the metals work has been a mystery. view more (2006-02-27)
Young supernova remnants not dusty enough, according to UC Berkeley astronomers
One of the youngest supernova remnants known, a glowing red ball of dust created by the explosion 1,000 years ago of a supermassive star in a nearby galaxy, the Small Magellanic Cloud, exhibits the same problem as exploding stars in our own galaxy: too little dust. view more (2006-06-07)
New stars from old gas surprise astronomers
Evidence of star birth within a cloud of primordial gas has given astronomers a glimpse of a previously unknown mode of galaxy formation. The cloud, known as the Leo Ring, appears to lack the dark matter and heavy elements normally found in galaxies today. view more (2009-02-19)
Do the hyper-coordinate planar transition metal atoms exist?
A study reported in Vol 51, Issue 7 (July, 2008) of Science in China Series B: Chemistry has shown that wheel-shaped structures with octa- and enneacoordinate planar cobalt, iron and nickel centered in perfect octagonal and enneagonal boron rings, are stable on corresponding potential hyper-surfaces. This suggests that the central element bonding... view more... (2008-07-01)
Heavy drinkers face significantly increased cancer risk
Heavy drinkers of beer and spirits face a much higher risk of developing cancer than the population at large, says a group of Montreal epidemiologists and cancer researchers. view more (2009-08-04)
Heavy drinking by both sexes is a cause for concern
Heavy drinking is common and a cause for concern in both young men and young women, according to a letter in this week’s BMJ. view more (2002-03-20)
Air pollution link to clogged arteries
Should we be watching our exposure to airborne pollution as well as our cholesterol levels" Research now indicates that air pollution has a role to play in atherosclerosis (artery hardening), which can contribute to heart attacks or strokes. view more (2007-07-26)
