Surprising new water property discovered
At a microscopic level, water molecules behave rather like the needle of a compass. Just as the needle moves when surrounded by a magnetic field (such as that of the Earth), water molecules move slightly in one direction when there is an electric field. Or at least that is what physicists thought till now. Research at the Universitat... view more... (2004-05-13)
Warm water vibrates for longer
Dutch researcher Arjan Lock has investigated the behaviour of vibrating water molecules. Using ultra-short laser pulses, he found that hydrogen atoms in water molecules vibrate for longer at higher temperatures. This is abnormal because in the majority of substances a vibration lives shorter at higher temperatures. Lock studied the OH-stretch... view more... (2004-02-05)
Identifying the 'signatures' of protons in water
Free protons from acids associate with 1, 2 or 3 molecules of water and the structures can be identified by unique infrared laser spectrum signatures, according to a report in Science by Yale professor of chemistry Mark A. Johnson and his collaborators at Yale, the University of Pittsburgh and the University of Georgia. view more (2005-07-14)
Physicists reveal water's secrets in journal 'Science'
It's essential to all life, and numerous research papers are published about it every year. Yet there are still secrets to reveal about water, that seemingly simple compound we know as H2O. view more (2007-03-05)
Just like old times: Generating RNA molecules in water
A key question in the origin of biological molecules like RNA and DNA is how they first came together billions of years ago from simple precursors. view more (2009-11-23)
Simulations help explain fast water transport in nanotubes
By discovering the physical mechanism behind the rapid transport of water in carbon nanotubes, scientists at the University of Illinois have moved a step closer to ultra-efficient, next-generation nanofluidic devices for drug delivery, water purification and nano-manufacturing. view more (2008-09-17)
'Micro-boxes' of water used to study single molecules
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated the use of water droplets as minuscule "boxes" for small numbers of biomolecules. view more (2006-07-24)
PhD student filters water vapour information from satellite data
PhD student Rüdiger Lang has developed a method to obtain information about water vapour from satellite data not specifically measuring this. The research is part of a project from the FOM Institute for Atomic and Molecular Physics (AMOLF), the Space Research Organisation Netherlands (SRON) and the Free University of Amsterdam. Water vapour... view more... (2002-10-24)
Smart thin film membranes adopt properties of guest molecules
Virginia Tech researchers announced last year that they had created a nanostructured membrane that incorporates DNA base pairs in order to impart molecular recognition and binding ability to the synthetic material. view more (2007-03-29)
Water is 'designer fluid' that helps proteins change shape, scientists say
Ubiquitous on Earth, water also has been found in comets, on Mars and in molecular clouds in interstellar space. Now, scientists say this common fluid is not as well understood as we thought. view more (2008-08-07)
Plastic-Protein Hybrid Materials
Enzymatic films for bioactive surfaces We encounter them every day in laundry detergent, dishwashing liquid, or shower gel: surfactants - surface-active substances. Surfactants belong to a category of molecules called amphiphiles, molecular hermaphrodites consisting of a water-loving (hydrophilic) "head" and a water-hating (hydrophobic) "tail".... view more...

Genetically engineered blood protein can be used to split water into oxygen and hydrogen
Scientists have combined two molecules that occur naturally in blood to engineer a molecular complex that uses solar energy to split water into hydrogen and oxygen. view more (2006-12-01)
Algae understand the language of bacteria
It has hitherto not been known that higher organisms, such as green algae, can communicate with bacteria. But Debra Milton, associate professor at Ume'å University in Sweden, shows in the recent issue of the prominent journal Science that bacteria attract green algae with the aid of signal molecules. Surfaces under water are rapidly... view more... (2002-11-12)
New tool gives researchers a glimpse of biomolecules in motion
The ability of biomolecules to flex and bend is important for the performance of many functions within living cells. view more (2009-01-14)
Water, water, everywhere - CMD19/CMMP with The Physics Congress 2002
Over half our planet is covered in water, and life cannot exist without it. But despite how common and important it is, surprisingly little is known about the structure of water, especially when it is next to other materials. A detailed understanding of how water behaves would not only reveal how biomolecules assemble or function - and possibly... view more... (2002-03-26)
UAB scientists discover the origin of a mysterious force
Scientists at the Universitat Autònoma de Barcelona and Imperial College London have discovered the origin of hydration force, a phenomenon that causes some complex chemical and biochemical species (including DNA and other electrostatically charged molecules) to repel at short distances when surrounded by water. Through this research,... view more... (2005-02-28)
A single water molecule acting as gate keeper
How do the bonds cells form with their environments rupture? What enables some cells to migrate? It is known since quite a while that cells can have complex mechanical interactions with their environments. Not only the biochemical but also the physical properties of their environment can thus have significant impact on cell behavior and even gene... view more... (2004-11-12)
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 trapped underneath the surface". Dr Siller will be... view more... (2002-03-26)
The smallest piece of ice reveals its true nature
Collaborative research between scientists in the UK and Germany (published in this week's Nature Materials) has led to a breakthrough in the understanding of the formation of ice. view more (2007-06-21)
Clues to our birth may be written in space
Extraterrestrial molecules found in meteorites may hold the key to the origin of life on Earth, according to chemistry research at the University. view more (2005-01-21)
