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... view more (1999-04-13)

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... view more (2005-07-12)

Small molecules may explain psoriasis
A research team at the Swedish medical university Karolinska Institutet has shown for the time that microRNA, small RNA molecules, may play an important role in the development of inflammatory skin diseases such as psoriasis and atopic eczema.   view more (2007-07-12)

Rapid movements of living biomolecules visualised
Dutch researcher Chris Molenaar has made the rapid movements of proteins, DNA and RNA molecules visible in living cells. With this technique researchers can study the dynamics of biomolecules in their natural environment. Molenaar developed a method which makes it possible to follow the movements... view more (2003-06-24)

New materials for high efficiency organic solid state lighting
A new organic molecule developed by Pacific Northwest National Laboratory scientists may significantly improve the efficiency of organic solid state lighting. Direct conversion of electricity to light in "solid state" thin films of organic molecules occurs in organic light emitting... view more (2006-03-30)

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... view more (2002-11-12)

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)

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... 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)

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)

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)

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... 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... 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... 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... view more (2005-07-14)

Baxter and Jerini advance program to develop non-intravenous haemophilia therapy
Baxter AG and Jerini AG today announced progress in their collaborative research program to develop a non-intravenous therapy for the treatment of hemophilia. Extensive in vitro and in vivo analysis has identified several synthetic lead molecules with promising pharmacological properties.   view more (2006-06-20)

Research into viral infections: Cardiff University enters agreement with Glaxo Wellcome Inc.
The collaboration is based on the work of the research group of Professor Chris McGuigan at Cardiff University's Welsh School of Pharmacy, which has discovered a new method for inserting charged molecules into living cells. The Cardiff team is collaborating with virologists at the Rega Institute1... view more (1999-07-20)
