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...

Researchers find lack of key molecule leads to deafness
Researchers have identified tiny molecules that may lead to big breakthroughs in the treatment of hearing loss and deafness. view more (2009-04-17)
Protein protects embryonic stem cells' versatility and self-renewal
A protein known as REST blocks the expression of a microRNA that prevents embryonic stem cells from reproducing themselves and causes them to differentiate into specific cell types, scientists at The University of Texas M. D. Anderson Cancer Center report in the journal Nature. view more (2008-03-24)
New Class of RNA Molecules May Be Important in Human Cancer
Research here shows that an obscure form of RNA, part of the protein-making machinery in all cells, might play an important role in human cancer. view more (2007-09-12)
International research team seeks to unravel flatworm regeneration
Planarian flatworms are only a few millimeters up to a few centimeters in length, live in freshwater and are the object of intense research, because they possess the extraordinary ability to regenerate lost tissue with the help of their stem cells (neoblasts) and even grow an entirely new worm out of minute amputated body parts. view more (2009-07-21)
A small leak will sink a great ship
Flowers of higher plants are built in a similar pattern: their outermost whorl is composed of sepals, which protect the young bud, thereafter comes a whorl of often colorful petals attracting insect pollinators, followed by a whorl of stamens with pollen sacks and the innermost whorl holds carpels, which later give rise to the fruit and seeds. view more (2007-06-27)
MicroRNAs help zebrafish regenerate fins
Biologists have discovered a molecular circuit breaker that controls a zebrafish's remarkable ability to regrow missing fins, according to a new study from Duke University Medical Center. view more (2008-03-17)
Toward the design of greener consumer products
So you're a manufacturer about to introduce a new consumer product to the marketplace. Will that product or the manufacture of the product contribute to global warming through the greenhouse effect? view more (2009-09-17)
New rotors could help develop nanoscale generators
In collaboration with the Chinese Academy of Sciences in Beijing, scientists have investigated the rotation of molecules on a fixed surface to understand how they may help in the development of future rotor-based machinery at nanoscale level. view more (2009-05-28)
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)
Lung cancer suppresses miR-200 to invade and spread
Primary lung cancer shifts to metastatic disease by suppressing a family of small molecules that normally locks the tumor in a noninvasive state, researchers at The University of Texas M. D. Anderson Cancer Center report in the Sept. 15 edition of Genes and Development. view more (2009-09-15)
University of Oklahoma Researchers Discover Giant Rydberg Atom Molecules
A group of University of Oklahoma researchers led by Dr. James P. Shaffer, Homer L. Dodge Department of Physics and Astronomy, have discovered giant Rydberg molecules with a bond as large as a red blood cell. view more (2009-06-25)
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 of RNA molecules in living cells. The researcher... 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 devices which can be far more efficient than... view more... (2006-03-30)
Experimental agent reduces breast cancer metastasis to bone
Researchers have reduced breast cancer metastasis to bone using an experimental agent to inhibit ROCK, a protein that was found to be over-expressed in metastatic breast cancer. view more (2009-11-04)
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 molecules. Surfaces under water are rapidly... view more... (2002-11-12)
Researchers identify another potential biomarker
Researchers from Boston University School of Medicine (BUSM) have demonstrated that a recently discovered class of molecule called microRNA (miRNAs), regulate the gene expression changes in airway cells that occur with smoking and lung cancer. view more (2009-01-14)
In touch with molecules
The performance of modern electronics increases steadily on a fast pace thanks to the ongoing miniaturization of the utilized components. view more (2009-11-13)
UC Davis researchers identify a cellular pathway that makes prostate cancer fatal
Expanding evidence that tiny strands of RNA - called microRNAs - play big roles in the progress of some cancers, UC Davis researchers have identified one that helps jump start prostate cancer cell growth midway through the disease process, eventually causing it to become fatal. view more (2007-11-28)
