Not just humans benefit from animal biotechnology
Laboratory animals are the source of major discoveries and breakthroughs in biology, not just in tackling disease but also unravelling fundamental molecular processes. Delegates at a recent research conference organised by the European Science Foundation (ESF) and Wellcome Trust heard how technology capable of analysing animal genes across the... view more...

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)
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)
Arterial, venous or total mesenteric ischemia/reperfusion causes different types of injury?
It is known that I/R induces an inflammatory response deleterious to the organ involved but also to the system as a whole. view more (2009-08-27)
MicroRNA undermines tumor suppression
Scientists at the Whitehead Institute for Biomedical Research and the National University of Singapore have discovered the first microRNA (miRNA) capable of directly tamping down the activity of the well known tumor-suppressor gene, p53, While p53 functions to prevent tumor formation, the p53 gene is thought to malfunction in more than 50% of... view more...

Synthetic molecules hold promise for new family of anti-cancer drugs
Synthetic molecules designed by two Hebrew University of Jerusalem researchers have succeeded in reducing and even eliminating the growth of human malignant tissues in mice, while having no toxic effects on normal tissue. view more (2008-06-05)
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)
Scientists make step forward in drug detection
Scientists at The University of Nottingham are leading the field in developing a new detection system that could be used to test athletes for performance-enhancing drugs. view more (2005-02-16)
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)
New genetic marker characterizes aggressiveness of cancer cells
Levels of a small non-coding RNA molecule called let-7 appear to define different stages of cancer better than some of the "classical" markers for tumor progression. view more (2007-06-26)
Argonne scientists use lasers to align molecules
Protein crystallographers have only scratched the surface of the human proteins important for drug interactions because of difficulties crystallizing the molecules for synchrotron x-ray diffraction. view more (2008-05-14)
Gladstone scientists identify genetic factors that hold promise for treatment of vascular diseases
Researchers at the Gladstone Institute of Cardiovascular Disease (GICD) have discovered a key switch that makes stem cells turn into the type of muscle cells that reside in the wall of blood vessels. view more (2009-07-06)
Scientists deliver the next generation of hair care products
Proteins perform a number of vital functions in the body at a biochemical level; one of which is to carry and deliver essential molecules to specific areas. On reaching their destination, they deliver their cargo by attaching to the target. view more (1999-07-13)
Diabetes treatment may lie in helping muscles to burn fat better
Scientists in Sydney and Melbourne have produced results that could silence the current debate about exactly how fat molecules clog up muscle cells, making them less responsive to insulin. view more (2009-01-28)
Molecules in glass houses
Trapping biological molecules such as proteins and enzymes or even whole cells in rigid structures make them easier to use for a whole range of industrial and medical applications. But combining fragile biological molecules with tough materials is difficult to do without damaging the molecules and destroying their biological activity. As well as... view more... (2001-08-01)
Nano machine of the future captures great scientist's bold vision
An idea conceived by one of the world's greatest scientists nearly 150 years ago has finally been realised with a tiny machine that could eventually lead to lasers moving objects remotely. view more (2007-02-02)
Gold nanoparticles prove to be hot stuff
Gold nanoparticles are highly efficient and sensitive "handles" for biological molecules being manipulated and tracked by lasers, but they also can heat up fast-by tens of degrees in just a few nanoseconds-which could either damage the molecules or help study them. view more (2006-09-01)
Using Carbon Nanotubes For Quantum Computing
The computing community for many years has longed to be able to to carry out high speed calculations using a genuine Quantum Computer because it would facilitate the practical factorisation of very large numbers and the searching of unordered lists and databases. The rapid breaking of secure codes based on prime numbers would have a lot of... view more... (2004-07-15)
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)
