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)
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)
Argonne scientists develop techniques for creating molecular movies
They may never win an Oscar, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory have developed techniques for creating accurate movies of biological and chemical molecules, a feat only theorized up until now. view more (2008-04-16)
Prediction of RNA pseudoknots using heuristic modeling with mapping and sequential folding
An algorithm utilizing structure mapping and thermodynamics is introduced for RNA pseudoknot prediction. The method finds the minimum free energy in the context of the biological folding direction (5' to 3') of RNA sequences. view more (2007-09-19)
Affibody ligands to Finnzymes
Affibody AB and Finnzymes Oy today announce that they have established a collaboration. The scope of the collaboration is to develop Affibody® affinity ligands for use in amplification of genetic material. Under the agreement, Affibody will develop specific affinity ligands, Affibody® molecules, to be used in kits for HotStart polymerase... view more... (2004-03-24)
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)
Where is the proton? Yale scientists discover footprints of shared protons
This week in Science, Yale researchers present "roadmaps" showing that shared protons, a common loose link between two biological molecules, simply vibrate between the molecules as a local oscillator, rather than intimately entangling with the molecular vibrations of the attached molecules. view more (2007-04-13)
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 decisive for the correct functioning of the cells and... view more... (2003-01-15)
Nanoneedle is small in size, but huge in applications
Researchers at the University of Illinois have developed a membrane-penetrating nanoneedle for the targeted delivery of one or more molecules into the cytoplasm or the nucleus of living cells. view more (2009-04-29)
MicroRNAs play a big part in gene regulation-and evolution
egulating when and where certain proteins are made is crucial to the normal functioning of living things. To make proteins, information from DNA is transcribed into RNA molecules and then translated into the amino acids building blocks of proteins. view more (2005-06-24)
Leeds researchers reshape the future of drug discovery
Scientists in Leeds have devised a new way to create the next generation of man-made molecules in a breakthrough that could revolutionise drug development. view more (2008-11-19)
Researchers Find Synthetic Molecules That May Literally Be The Key To “Locking Away” Unwanted DNA
Research chemists have a found a class of synthetic molecules that could quite literally act as a key which could lock away sections of DNA into a closely wound coil preventing proteins from interacting with particular sections of DNA code. By locking up the DNA in this way scientists could stop particular sequences of DNA from activating... view more... (2002-04-15)
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)
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)
New imaging method lets scientists 'see' cell molecules more clearly
Scientists have always wanted to take a closer look at biological systems and materials. From the magnifying glass to the electron microscope, they have developed ever-increasingly sophisticated imaging devices. view more (2009-01-21)
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)
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 that recognizes molecules by their shape. To... 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 help them resist attack by immune cells called... view more...

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)
Using evolution, UW team creates a template for many new therapeutic agents
By guiding an enzyme down a new evolutionary pathway, a team of University of Wisconsin-Madison researchers has created a new form of an enzyme capable of producing a range of potential new therapeutic agents with anticancer and antibiotic properties. view more (2007-09-10)
