Math Models Snowflakes
Three-dimensional snowflakes can now be grown in a computer using a program developed by mathematicians at UC Davis and the University of Wisconsin-Madison. view more (2008-01-17)
Rehydrate - your RNA needs it
Water, that molecule-of-all-trades, is famous for its roles in shaping the Earth, sustaining living creatures and serving as a universal solvent. view more (2006-08-23)
Better MRI scans of cancers made possible by TU Delft
Researcher Kristina Djanashvili has developed a substance that enables doctors to get better MRI scans of tumours. On Tuesday 13 January, Djanashvili will be awarded a doctorate by TU Delft for her work in this field. view more (2009-01-13)
Electrons 'tunnel' through water molecules between nestled proteins
Duke University theoretical chemists who spend much of their time calculating how the exotic rules of quantum mechanics govern electrons motion between and through biological molecules have garnered surprising results when they add water to their models. view more (2005-11-28)
Comet probes reveal evidence of origin of life, scientists claim
Recent probes inside comets show it is overwhelmingly likely that life began in space, according to a new paper by Cardiff University scientists. view more (2007-08-15)
Catcher in the Rye
The development of sensors that can selectively fish a specific type of molecule out of a mixture is among the highest goals of many chemists. Vladimir M. Mirsky and his coworkers at the University of Regensburg have now come close to meeting this objective - with a clever coating for electrodes that recognizes molecules by their shape. To... view more... (1999-04-13)
Cleaning up pollutants with sunlight
A cheap, harmless chemical and sunlight could provide an environmentally friendly way of destroying micro-pollutants in the environment. UK researchers are developing a new type of reactor to destroy persistent contaminants such as pesticides and pharmaceutical residues. The technology, which breaks down the polluting molecules into carbon... view more... (2002-10-23)
Did comets flood Earth's oceans?
Did the Earth form with water locked into its rocks, which then gradually leaked out over millions of years? Or did the occasional impacting comet provide the Earth's oceans? The Ptolemy experiment on Rosetta may just find out"¦ The Earth needed a supply of water for its oceans, and the comets are large celestial icebergs - frozen... view more... (2004-06-16)
Unique imaging uncovers the invisible world where surfaces meet
Hoping to find new ways of addressing environmental pollution, a physicist at the University of Wisconsin-Milwaukee (UWM) has developed some novel ways to observe what happens inside a cell when it comes in contact with contaminants or when toxic substances touch soil and water. view more (2006-10-30)
Molecules wrestle for supremacy in creation of superstructures
Research at the University of Liverpool has found how mirror-image molecules gain control over each other and dictate the physical state of superstructures. view more (2009-08-14)
Alloy of hydrogen and oxygen made from water
Water, the only indispensable ingredient of life, is just about the most versatile stuff on Earth. Depending on its temperature we can heat our homes with it, bathe in it, and even strap on skates and glide across it, to name only the most common of its many forms. When subjected to high pressures, however, water can take any of more than 15... view more... (2006-10-27)
Colorful bacteria more dangerous
A new study in the July 18 issue of The Journal of Experimental Medicine shows that gold-colored bacteria are more harmful than their unpigmented relatives. A group of scientists led by Victor Nizet (UCSD, San Diego, CA) have discovered that the molecules that give certain bugs their color also help them resist attack by immune cells called... view more...

Weird water: Discovery challenges long-held beliefs about water's special properties
Beyond its role as the elixir of all life, water is a very unusual substance: Scientists have long marveled over counter-intuitive properties that set water apart from other solids and liquids commonly found in nature. view more (2008-01-21)
Lovely 'snowfakes' mimic nature, advance science
Exquisitely detailed and beautifully symmetrical, the snowflakes that David Griffeath makes are icy jewels of art. view more (2009-02-25)
Nano propellers pump with proper chemistry
The ability to pump liquids at the cellular scale opens up exciting possibilities, such as precisely targeting medicines and regulating flow into and out of cells. But designing this molecular machinery has proven difficult. view more (2007-07-17)
Atomic force microscopy reveals liquids adjust viscosity when confined, shaken
Getting ketchup out of the bottle isn't always easy. However, shaking the bottle before trying to pour allows the thick, gooey ketchup to flow more freely because it becomes more fluid when agitated. The opposite is not typically true - a liquid such as water does not become a gel when shaken. view more (2008-04-30)
Where is the proton? Yale scientists discover footprints of shared protons
This week in Science, Yale researchers present "roadmaps" showing that shared protons, a common loose link between two biological molecules, simply vibrate between the molecules as a local oscillator, rather than intimately entangling with the molecular vibrations of the attached molecules. view more (2007-04-13)
Water and Nanoelectronics Will Mix to Create Ultra-Dense Memory Storage Devices, Researchers Say
Excessive moisture can typically wreak havoc on electronic devices, but now researchers have demonstrated that a little water can help create ultra-dense storage systems for computers and electronics. view more (2006-04-28)
Groundbreaking biomedical researchers receive £395,000
Internationally leading biomedical research at the University of Sussex involving the development of anti-cancer drugs and gene therapy applications has been boosted by a £395,519 grant. The funding from the Engineering and Physical Sciences Research Council (EPSRC) was made to chemistry professors Norman Billingham and Steven Armes, whose... view more... (2003-03-13)
Quick Test for Polluted Environments
The "Biotool" project seeks to use bacterial marker molecules for predictions view more (2005-01-18)
