Researchers think pink to produce 'green' solar energy
When it comes to producing earth-friendly solar energy, pink may be the new green, according to Ohio State University researchers. Scientists here have developed new dye-sensitized solar cells, that get their pink color from a mixture of red dye and white metal oxide powder in materials that capture light. view more (2007-07-31)
Nitrous oxide from ocean microbes
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing today. view more (2007-12-11)
Too little attention is paid to the side effects of emission-limiting measures
With measures aimed at reducing the emission of pollutants such as ammonia, policy makers pay too little attention to the consequences for the emission of other substances. This is revealed in a computer model constructed by Corjan Brink from Wageningen University during his doctoral research. For example, the model shows that reducing the amount... view more...

Guggenheim Bilbao museum gleaming again
Originality and suitability of titanium sheets that cover the exterior of the building was highlighted, among other things, the day Guggenheim Bilbao museum was opened - October 1997. Titanium, apart from being spectacular, is a material that does not require special maintenance. It is a light material and has a great resistance against salt water... view more... (2001-07-10)

LAUGHING GAS - A FASHIONABLE RECREATIONAL DRUG? (p 1347)
Issue 19 April 2003 Embargoed 0001 h (London time) 18 April 2003 New Zealand authors of a research letter in this week's issue of THE LANCET report how laughing gas may be a popular recreational drug among young people. This could have implications for public health, as a case report in THE LANCET last year highlighted how excessive use of... view more... (2003-04-16)
Hydrogen found to transmit magnetism
A team of chemists and physicists at the Universities of Liverpool and Oxford have shown that hydrogen transmits magnetism. This discovery could be the first step to a new class of magnetic materials, and opens up a new field of chemistry. The team, headed by Professor Matthew Rosseinsky of the Department of Chemistry, University of Liverpool, and... view more... (2002-03-07)
Fat transforms vitamin C from 'good cop' into 'bad cop'
Fat in the stomach may cause vitamin C to promote, rather than prevent, the formation of certain cancer causing chemicals, reveals research published ahead of print in the journal Gut. view more (2007-09-04)
Geologists reveal secrets behind supervolcano eruption
Researchers at Rensselaer Polytechnic Institute have discovered what likely triggered the eruption of a "supervolcano" that coated much of the western half of the United States with ash fallout 760,000 years ago. view more (2007-03-06)
Bone-Growing Nanomaterial Could Improve Orthopaedic Implants
For orthopaedic implants to be successful, bone must meld to the metal that these artificial hips, knees and shoulders are made of. A team of Brown University engineers, led by Thomas Webster, has discovered a new material that could significantly increase this success rate. view more (2007-09-18)
Nitric oxide plays a vital role in the formation of long-term memory in snails
Snails can teach us a great deal about how we form memories, according to a group of neuroscientists at the University of Sussex. Research by Dr Ildik'³ Kemenes, Professor Paul Benjamin, Professor Michael O'Shea and colleagues shows that nitric oxide plays a vital role in the formation of long-term memory in snails. This is of crucial importance... view more... (2002-02-18)
NITRIC OXIDE BENEFIT FOR INFANTS UNDERGOING CONGENITAL HEART SURGERY (p 1464)
The cardiovascular problems associated with surgery for congenital heart disease in infants may be reduced with the use of postoperative nitric oxide, according to research published in this week's issue of THE LANCET. Congenital heart disease is present in five to ten per 1000 livebirths. If surgery is required, the most common defects are... view more... (2000-10-25)
