Strengthening case for life on Mars - CMD19CMMP with The Physics Congress 2002
When it was announced last month that the Mars Odyssey satellite had found water ice beneath the planet`s frozen carbon dioxide south polar ice cap, "I felt excited!" says Dr Lidija Siller, a physicist from the University of Newcastle. "I believe that the data I have explains how this water became... view more (2002-03-26)
Researchers shed more light on conversion of water to hydrogen gas

Atmospheric chemistry - air quality and climate
Air quality has improved dramatically over the past 50 years. Professor Mike Pilling, Head of Physical Chemistry at the University of Leeds, will reveal the latest about air quality research at the Festival of Science today. view more (2004-09-06)
Mars Express confirms methane in the Martian atmosphere
During recent observations from the ESA Mars Express spacecraft in orbit around Mars, methane was detected in its atmosphere. Whilst it is too early to draw any conclusions on its origin, exciting as they may be, scientists are thinking about the next steps to take in order to understand more.... view more (2004-03-30)
Fingerprinting air - new breakthrough at University of Leicester
The University of Leicester has developed a new 'air fingerprinting' technique which can detect, in less than a minute, the 'ingredients' of air including that of an individual's breath or perfume. This technique revolutionises the speed and accuracy by which air composition can be tested and has... view more (2004-06-07)
Newly detected air pollutant mimics damaging effects of cigarette smoke
A previously unrecognized group of air pollutants could have effects remarkably similar to harmful substances found in tobacco smoke, Louisiana scientists are reporting in a study scheduled for presentation today at the 236th National Meeting of the American Chemical Society. view more (2008-08-18)

Sulfur signature changes thoughts on atmospheric oxygen
Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when the Earth's atmosphere began to contain oxygen. view more (2006-08-24)
Nanomaterials vulnerable to dispersal in natural environment
Laboratory experiments with a type of nanomaterial that has great promise for industrial use show significant potential for dispersal in aquatic environments - especially when natural organic materials are present. view more (2006-12-19)
Hubble finds first organic molecule on extrasolar planet
The tell-tale signature of the molecule methane in the atmosphere of the Jupiter-sized extrasolar planet HD 189733b has been found with the Hubble Space Telescope. Under the right circumstances methane can play a key role in prebiotic chemistry - the chemical reactions considered necessary to form... view more (2008-03-20)
Computer models suggest planetary and extrasolar planet atmospheres
The world is abuzz with the discovery of an extrasolar, Earth-like planet around the star Gliese 581 that is relatively close to our Earth at 20 light years away in the constellation Libra. view more (2007-06-20)
Controversial findings help explain evolution of life
Chemists at Oregon State University have pioneered a controversial theory about how supposedly-stable DNA bases can be pushed into a "dark state" in which they are highly vulnerable to damage from ultraviolet radiation - an idea that has challenged some of the most basic concepts of... view more (2006-04-07)
