Beyond the bonds that bind: UCSB researchers discover hydrogen can form multicenter bonds
Researchers at the University of California, Santa Barbara have shown that, under the right circumstances, hydrogen can form multicenter bonds, where one hydrogen atom simultaneously bonds to as many as four or six other atoms. view more (2006-12-04)
Spider silk reveals a paradox of super-strength
Since its development in China thousands of years ago, silk from silkworms, spiders and other insects has been used for high-end, luxury fabrics as well as for parachutes and medical sutures. view more (2010-03-18)
Solvents in Retreat
A new catalyst for selective solvent-free hydrogenation at low temperatures A number of cyclic hydrocarbons with multiple double bonds are readily accessible intermediates in chemical industry. In the course of further processing it is often necessary to saturate some of the double bonds with hydrogen to form single bonds. This type of reaction,... view more... (2001-03-27)
Genomics reveals mechanism of heat resistance in bacteria
Warm-blooded creatures maintain a relatively stable body temperature that cannot tolerate the stress of intense heat (or cold). view more (2005-08-23)
Sexual harassment from males prevents female bonding, says study
The extent to which sexual harassment from males can damage relationships between females is revealed in a study published today. view more (2009-04-22)
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)
DNA-Proofed Documents To Arrive 'By 2006'
The commercial launch of the first ever fool-proof document security system is planned for 2006, reports Marina Murphy in Chemistry & Industry magazine. The system, which uses DNA fingerprinting, will allow documents to be authenticated with an accuracy of billions to one against duplication, according to the Australian scientists working on... view more...

Tiny protein provokes healthy bonding between cells
In human relationships, a certain "spark" often governs whether we prefer one person to another, and critical first impressions can occur within seconds. A team lead by Johns Hopkins researchers has found that cell-to-cell "friendships" operate in much the same way and that dysfunctional bonding is linked to the spread of... view more... (2008-11-26)
Breaking harmful bonds
Everybody loves the way breakfast eggs conveniently slide off of Teflon without leaving any pesky pieces of egg in the pan. Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful we also use it in clothing, lubricants, refrigerants, anesthetics, semiconductors, and even blood substitutes. view more (2008-08-29)
Strange molecule in the sky cleans acid rain, scientists discover
Researchers have discovered an unusual molecule that is essential to the atmosphere's ability to break down pollutants, especially the compounds that cause acid rain. view more (2008-08-13)
Scripps Research team develops cheap, easy 'kitchen chemistry' to perform formerly complex synthesis
A team at The Scripps Research Institute has made major strides in solving a problem that has been plaguing chemists for many years: how best to break carbon-hydrogen bonds and then to create new bonds to join molecules together. view more (2009-12-04)
Unlike rubber bands, molecular bonds may not break faster when pulled
From balloons to rubber bands, things always break faster when stretched. view more (2009-06-18)
A sweet step toward new cancer therapies
By recognizing sugars, a technique developed by University of Michigan analytical chemist Kristina Hakansson sets the stage for new cancer diagnosis and treatment options. view more (2007-04-02)
The short-term memory of water
Researchers of the Max-Born-Institute and the University of Toronto find extremely fast fluctuations in liquid water - Publication in Nature. view more (2005-03-07)
New model predicts damage to cheese
Researchers at a Dutch university have developed a model that predicts how cheese will change when a force is applied to it. This makes it possible to predict how cheese will be damaged during the packaging or transportation processes. Anna Rzepiela from Wageningen University simulated the influence of shearing and tensional forces on the... view more... (2003-04-11)
Nanotechnology may increase longevity of dental fillings
Tooth-colored fillings may be more attractive than silver ones, but the bonds between the white filling and the tooth quickly age and degrade. view more (2009-07-02)
What happens when ice melts?
How molecules are linked together to form liquid water is the subject of a groundbreaking study due to appear Thursday, Apr. 1 in Science magazine's advance publication web site Science Express. The investigation entitled The Structure of the First Coordination Shell in Liquid Water summarizes the results of an international collaboration headed... view more... (2004-04-02)
Researchers describe 'implausible' chemistry that produces herbicidal compound
A soil microbe that uses chemical warfare to fight off competitors employs an unusual chemical pathway in the manufacture of its arsenal, researchers report, making use of an enzyme that can do what no other enzyme is known to do: break a non-activated carbon-carbon bond in a single step. view more (2009-06-11)
Breaking the Ties that Bind: New Hope for Biomass Fuels
Los Alamos National Laboratory researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough. view more (2009-04-23)
K-State research shows consumers can predict inflation as well as professional economists
When it comes to predicting the rate of inflation, professional economists might tell consumers, "Your guess is as good as mine." view more (2008-08-26)
