DNA’s oscillating double helix hinders electrical conduction
DNA has an oscillating double-helix structure. This oscillating means that the DNA molecules conduct electricity much less well than was previously thought. Ultrafast cameras were one of the devices the researchers from Amsterdam used to demonstrate this. It turns out the DNA does not have a rigid... view more (2002-09-11)

Writing at the nanoscale
At the U.S. Department of Energy's Brookhaven National Laboratory, scientists have developed a new chemical "writing" technique that can create lines of "ink" only a few tens of nanometers, or billionths of a meter, in width.   view more (2005-08-29)

ETH Researchers Visualize the Binding of Proteins to the Nuclear Surface
Not only the genetic information of individual cells, but also that of the entire organism is stored within the cell nucleus. Each cell of a multicellular organism, e.g. man, contains the identical DNA sequences. The communication between the cell nucleus and the remainder of the cell is thus... view more (2003-01-15)

Hubble finds carbon dioxide on an extrasolar planet
The NASA/ESA Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star.   view more (2008-12-10)

New 'litmus test' could aid discovery of anti-cancer drugs
Using the unusual color properties of gold at the nanoscale, scientists at Northwestern University have developed a "litmus test" for DNA and small molecule binding that eventually could be used by pharmaceutical companies to rapidly identify promising candidates for new anti-cancer drugs.   view more (2006-03-29)

European Biotech Industry at risk under new EU consultation on technology transfer regulations
CORDIA to act as a platform to debate on partnership strategies The European Commission is running a consultation on new technology transfer licensing legislation, which, if accepted, could make licensing deals difficult to implement in the European Union. This could seriously hinder the... view more (2003-11-20)

Leeches provide source for cardiovascular drugs
The leech has recently confirmed its biomedical interest for scientists by showing that it contains an extensive list of new potential molecules that may become useful tools in the treatment of cardiovascular diseases.   view more (2005-10-26)

Scientists using laser light to detect potential diseases via breath samples, says new study
By blasting a person's breath with laser light, scientists from the National Institute of Standards and Technology and the University of Colorado at Boulder have shown that they can detect molecules that may be markers for diseases like asthma or cancer.   view more (2008-02-19)

Researchers compile 'molecular manual' for 100s of inherited diseases
An international research team has compiled the first catalogue of tissue-specific pathologies underlying hundreds of inherited diseases.   view more (2008-12-18)

RNA enzyme structure offers a glimpse into the origins of life
Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or "ribozyme," that carries out a fundamental reaction required to make new RNA molecules.   view more (2007-03-16)

UCLA chemists create nano valve
UCLA chemists have created the first nano valve that can be opened and closed at will to trap and release molecules. The discovery, federally funded by the National Science Foundation, will be published July 19 in the Proceedings of the National Academy of Sciences.   view more (2005-07-18)

Researchers explain odd oxygen bonding under pressure
Oxygen, the third most abundant element in the cosmos and essential to life on Earth, changes its forms dramatically under pressure transforming to a solid with spectacular colors. Eventually it becomes metallic and a superconductor.   view more (2008-08-05)

Chemical warfare agent detection technology used to treat lung disease
A new technique based on the same technology used to detect chemical warfare agents and explosives is being employed by scientists at The University of Manchester to treat hospital patients with lung disease.   view more (2006-01-24)

How body size is regulated: International study discovers ten new genes related to human growth
Scientists are beginning to unravel the question why people distinctly vary in size.   view more (2008-05-12)

Computer-designed molecule to clean up fluorocarbons?
The chemical bond between carbon and fluorine is one of the strongest in nature, and has been both a blessing and a curse in the complex history of fluorocarbons. Now, in a powerful demonstration of the relatively new field of "computational chemistry".   view more (2007-03-05)

Green tea compound suppresses factors causing cartilage, bone destruction in arthritis
In rheumatoid arthritis, a person's own immune system attacks the joints by activating the synovial tissue that lines the body's movable joints, causing inflammation, swelling, pain and eventually erosion of the bone and cartilage and deformation of the joint.   view more (2007-04-30)

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)

Optical 'frequency comb' can detect the breath of disease
Exhale on a cold winter day and you will see the water vapor coming out of your mouth. Light up your breath with a Nobel-Prize-related tool, and you could potentially detect trace amounts of over 1,000 compounds, some of which provide early warning signs of disease.   view more (2008-02-20)

Scientists uncover how hormones achieve their effects
New insights into the cellular signal chain through which pheromones stimulate mating in yeast have been gained by scientists at the European Molecular Biology Laboratory [EMBL].   view more (2007-10-23)

Clues to the cause of difficulty with swallowing in children
Eosinophilic esophagitis (EE) is disease that was first described in children only 20 years ago, but has shown a rising incidence in both children and adults.   view more (2007-01-19)

Molecular steps involved in the creation of gene-silencing MicroRNAs identified
First discovered only a few brief years ago, microRNAs are small, remarkably powerful molecules that appear to play a pivotal role in gene silencing, one of the body's main strategies for regulating its genome. A scant 22 nucleotides in length, miRNAs appear to work by binding to and somehow... view more (2005-06-23)

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)

How did chemical constituents essential to life arise on primitive Earth?
Experiments show that simple molecules can combine chemically rather than biologically to form the building blocks of DNA, the key component of all life forms. These processes might have taken place on primitive earth, but how they occur is an unsolved puzzle.   view more (2007-10-31)
