Comet probes reveal evidence of origin of life, scientists claim
Recent probes inside comets show it is overwhelmingly likely that life began in space, according to a new paper by Cardiff University scientists. view more (2007-08-15)
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)
Uncharged organic molecule can bind negatively charged ions
Indiana University Bloomington chemists have designed an organic molecule that binds negatively charged ions, a feat they hope will lead to the development of a whole new molecular toolbox for biologists, chemists and medical researchers who want to remove chlorine, fluorine and other negatively charged ions from their solutions. view more (2008-02-27)
UCR chemists identify organic molecules that mimic metals
A limitation in using hydrogen as a fuel in hydrogen-powered vehicles is the difficulty involved in storing it in a cost-effective and convenient manner. view more (2007-04-20)
Inside job: new radioactive agents for colon cancer work inside cells
Johns Hopkins scientists have developed a potentially novel way to fight colorectal cancer using tiny molecules to deliver potent barrages of radiation inside cancer cells, unlike current treatments that bind to the surface of cells and attack from the outside and cause unwanted side effects. view more (2007-10-10)
NTU professor discovers method to efficiently produce less toxic drugs using organic molecules
Nanyang Technological University (NTU)'s Associate Professor Zhong Guofu has made a significant contribution to the field of organic chemistry, in particular the study of using small organic molecules as catalysts, in the synthesis process called organocatalysis. view more (2009-07-08)
Bottoms up: Better organic semiconductors for printable electronics
Researchers from the National Institute of Standards and Technology (NIST) and Seoul National University (SNU) have learned how to tweak a new class of polymer-based semiconductors to better control the location and alignment of the components of the blend. view more (2008-09-05)
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)
Are comets at the origin of life on earth ?
For over 60 years now, the University of Liege Astrophysics and Geophysics Institute (IAGL) has been concerned with the study of comets. Again today, four of its researchers have just made a major discovery for the understanding of these celestial objects : a lot of extra heavy nitrogen detected in two comets suggests the presence of great... view more...

Identification of a key molecular pathway required for brain neural circuit formation
The research group of Dr. Frédéric Charron, a researcher at the Institut de recherches cliniques de Montréal (IRCM), has made a discovery which could help treat spinal cord injuries and neurodegenerative diseases. view more (2009-05-18)
Gold nanostars outshine the competition
Novel nanoparticles being tested at the National Institute of Standards and Technology (NIST) have researchers seeing stars. In a recent paper, NIST scientists used surface-enhanced Raman spectroscopy (SERS) to demonstrate that gold nanostars exhibit optical qualities that make them superior for chemical and biological sensing and imaging. view more (2008-10-16)
Cutting edge - Scientists have combined a cutting ribosyme activity with an unwinding helicase activity
Scientists have long toyed with the idea of putting to work a special class of biological catalysts, called ribozymes, as therapeutic agents. These molecular scissors would harness the activities of overly active genes that contribute to diseases like cancer by cutting their immediate products, messenger RNAs, into unusable pieces. The advantage... view more... (2002-05-10)
New study shows how genes control blood proteins important to health
A new study shows how genes control levels of many blood proteins implicated in disease. The findings are the result of an international collaboration between scientists at the University of Exeter, the National Institute on Aging, and the Tuscany and Florence Health Agencies. view more (2008-05-09)
Electronic structure of DNA revealed for 1st time by Hebrew University and collaborating researchers
Utilizing a technique that combines low temperature measurements and theoretical calculations, Hebrew University of Jerusalem scientists and others have revealed for the first time the electronic structure of single DNA molecules. view more (2008-02-29)
Molecule Plays Early Role In Nonsmoking Lung Cancer
The cause of lung cancer in never-smokers is poorly understood, but a study led by investigators at the Ohio State University Comprehensive Cancer Center and at the National Cancer Institute has identified a molecule believed to play an early and important role in its development. view more (2009-07-28)
Search reveals molecules that block Stat 3
Finding molecules that block the activity of the oncogene Stat3 (signal transducer and activator of transcription) required screening literally millions of compounds, using computers that compared the structure of the cancer-causing gene to those of the small molecules, said a Baylor College of Medicine researcher in a report that appears in the... view more...

LCD as a molecular magnifying glass
Dutch researcher Johan Hoogboom has developed a technique for making LCDs (liquid crystal displays) without the need for cleanrooms. This technique is simpler and cheaper than current methods and is based entirely upon the self-ordering of molecules on a surface. Furthermore, the chemist has shown that these LCDs can be used to make DNA visible to... view more... (2004-12-16)
Ultrafast laser spectrometer measures heat flow through molecules
Global warming isn't the only heat scientists are feeling. Another area in which heat flow is becoming crucial is the field of molecular electronics, where long-chain molecules attached to tiny electrodes are used to transport and switch electrons. view more (2007-08-10)
Depression model leaves mice with molecular scar
In addition to triggering a depression-like social withdrawal syndrome, repeated defeat by dominant animals leaves a mouse with an enduring "molecular scar" in its brain that could help to explain why depression is so difficult to cure. view more (2006-03-01)
Failed HIV Drug Gets Second Chance with Addition of Gold Nanoparticles
Researchers at North Carolina State University have discovered that adding tiny bits of gold to a failed HIV drug rekindle the drug's ability to stop the virus from invading the body's immune system. view more (2008-05-27)
