MIT powers up new battery for hybrid cars
Researchers at MIT have developed a new type of lithium battery that could become a cheaper alternative to the batteries that now power hybrid electric cars. view more (2006-02-17)
Extracting Metal from the Sea â€" the Environmentally Friendly Way
A novel method that uses bacteria to mine valuable minerals from the ocean has been developed. Nodules collected from the Indian Ocean seabed can be treated to extract scarce land-based minerals in an environmentally sound way, says research published in the Journal of Chemical Technology and Biotechnology. Using the marine species Bacillus M1,... view more... (2004-04-02)
Turning Sunlight into Liquid Fuels: Berkeley Lab Researchers Create a Nano-sized Photocatalyst for Artificial Photosynthesis
For millions of years, green plants have employed photosynthesis to capture energy from sunlight and convert it into electrochemical energy. A goal of scientists has been to develop an artificial version of photosynthesis that can be used to produce liquid fuels from carbon dioxide and water. view more (2009-03-11)
Warning over nitric oxide for lung injury patients
Use of nitric oxide in patients with acute lung injury does not improve survival and may cause harm, warn researchers in a study published on bmj.com today. view more (2007-03-23)
MIT researchers build tiny batteries with viruses
MIT scientists have harnessed the construction talents of tiny viruses to build ultra-small "nanowire" structures for use in very thin lithium-ion batteries. view more (2006-04-07)
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. When the electrons return to the free state, with... view more... (2000-01-18)
Physicists describe a new mechanism for metallic magnetism
Predicting the magnetic behavior of metallic compounds is a surprisingly difficult problem for theoretical physicists. view more (2005-08-26)
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)
The danger of blindness after ophthalmic surgery
Ophthalmologists inject gas into the eye mainly during the surgical treatment of retinal hemorrhages or injuries. The purpose of the gas is to help press the detached retina to the wall of the eye. view more (2008-02-26)
Reducing side effects of painkillers
Cardiff University researchers have increased the understanding of why some painkillers increase the risk of heart attack and stroke. view more (2006-09-13)
Shape matters in the case of cobalt nanoparticles
Shape is turning out to be a particularly important feature of some commercially important nanoparticles-but in subtle ways. view more (2009-06-18)
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...

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)
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)
New intestinal disease charted by Swedish researcher
Microscopic colitis is a newly discovered inflammatory intestinal disease that occurs in two different forms, lymphocytary colitis and collagenic colitis. Ã-rebro University, Sweden, is on the cutting edge of research on these diseases, and Martin Olesen is one of first scientists in the country to write a dissertation on the subject, defending... view more...

Researchers uncover E. coli's defense mechanism
The pathogenic forms of E. coli and Salmonella are usually transmitted to humans through undercooked meat, unwashed vegetables and cross contamination from surfaces on which these foods were prepared. view more (2005-09-29)
