Powerful new 'molecular GPS' helps probe aging and disease processes
Scientists in Michigan are reporting the development of a powerful new probe for identifying proteins affected by a key chemical process important in aging and disease. view more (2009-09-02)
Bacteria 'launch a shield' to resist attack
Researchers from the University of Copenhagen and the Technical University of Denmark along with other collaborators in Denmark and the US found that the bacterium Pseudomonas aeruginosa can 'switch on' production of molecules that kill white blood cells - preventing the bacteria being eliminated by the body's immune system. view more (2009-11-02)
Molds made of Sugar Rings
Synthesis of porous Silica with help from cyclodextrin aggregates view more (2001-11-30)
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)
Tethered Molecules Act as Light-Driven Reversible Nanoswitches
The ability to see is based on molecules in the eye that flip from one conformation to another when exposed to visible light. view more (2008-06-24)
MicroRNA-mediated metastasis suppression
Metastases are responsible for over 90% of cancer deaths. In the upcoming issue of G&D, Dr. Robert Weinberg (MIT) and colleagues lend molecular insight into how microRNAs suppress tumor metastasis. view more (2009-10-29)
NJIT professor finds engineering technique to identify disease-causing genes
Scientists believe that complex diseases such as schizophrenia, major depression and cancer are not caused by one, but a multitude of dysfunctional genes. view more (2008-10-29)
Targeted drug delivery now possible with 'pHLIP' peptide
Scientists at Yale and the University of Rhode Island report the development of a peptide that can specifically and directly deliver molecules to the inside of cells like a nanosyringe, creating a new tool for drug delivery, gene control and imaging of diseased tissues. view more (2006-04-12)
Molecules on a string, and why size isn't the only thing that matters for data storage
Molecules of hydrogen are difficult to steer with electric fields because of the symmetrical way that charges are distributed within them. But now researchers at ETH Zurich have found a clever technique to get a grip on the molecules. view more (2009-09-15)
Killer pulses help characterize special surfaces
Detecting deadly fumes in subways, toxic gases in chemical spills, and hidden explosives in baggage is becoming easier and more efficient with a measurement technique called surface-enhanced Raman scattering. To further improve the technique's sensitivity, scientists must design better scattering surfaces, and more effective ways of evaluating... view more... (2008-07-30)
Ice has a starring role - CMD19/CMMP with The Physics Congress 2002
When even moderately hot stars like our Sun have surface temperatures of around 6,000°C, it is hard to imagine that ice plays an important part in their formation. But that`s exactly what astrophysicists have recently discovered by turning to surface scientists for help. At the Condensed Matter conference on Monday 8 April, part of the... view more...

New nanochemistry technique encases single molecules in microdroplets
Inventing a useful new tool for creating chemical reactions between single molecules, scientists at the National Institute of Standards and Technology (NIST) have employed microfluidics-the manipulation of fluids at the microscopic scale-to make microdroplets that contain single molecules of interest. view more (2009-09-23)
The UAB heads a European research project on proteases and pathological processes
A research group of the UAB Institute of Biotechnology and Biomedicine and the UAB Department of Biochemistry and Molecular Biology, directed by Francesc Xavier Avilés, is the coordinator of a European project aimed at studying proteases with fluorescent molecules that allow their monitoring in healthy and pathological situations. view more (2007-07-18)
Pictures hardly subject to leaching during cleaning
If picture restorers are careful when using solvents, very few organic molecules are likely to be leached away from the paint layer. Serious leaching does however occur when paint samples are immersed in solvents. These are some of the results of a study carried out at the National Gallery of Art in Washington DC as part of NWO’s Molart... view more... (2001-05-30)
Making sense of the human genome: researchers characterize a crucial family of signaling proteins in the human genome
In this month's Genome Biology, Mitch Kostich and colleagues from the Schering-Plough Research Institute (NJ, USA) have identified and mapped an important group of molecules known as protein kinases. These molecules are central to the communication of information both within and between cells, in a process known as cell signaling. Defective... view more... (2002-08-23)
Exploiting Nature's Weapons in the Fight Against Diabetes
Scientists at the University of Ulster are harnessing molecules produced naturally in the body to tackle one of the world's major health problems - diabetes. Their novel approach involves bioengineering gut peptides - molecules produced in the human intestine and released in response to feeding - to prolong their duration of action and,... view more...

Study in mice suggests molecules in plants have beneficial effect on Alzheimer's disease
A set of molecules found in certain plants appears to have a beneficial effect in brain tissue associated with Alzheimer's disease, according to a new study conducted in mice. The study was led by researchers at the University of South Florida and Cedars-Sinai Medical Center. An article in the Journal of Cellular and Molecular Medicine is... view more... (2008-05-07)
Liquid crystal multilayer study promises improvements in manufacturing techniques for LCD's
In order to successfully fabricate a commercial Liquid Crystal Display, uniform orientation of the liquid crystal (LC) molecules is required. view more (2005-10-12)
Radicals Shake Up Molecules in a Tug o' War
Until now, it was commonly thought that colliding molecules get the shakes as the result of energy transfer solely from the smashing of the molecules, but some new research adds a second means by which colliding molecules become vibrationally excited--it is being called the "Tug o' War Mechanism." view more (2008-07-07)
Laser blasts will reveal structures and dynamics of molecules in the fastest events in nature
A new £2 million Research Centre at the University of York will provide unprecedented information on how molecules change, helping scientists understand the structure and dynamics of liquids, proteins and even our DNA. The York Centre for Laser Spectroscopy and Photochemistry opened today (29 October 2003), will use ultra-short laser light... view more... (2003-10-27)
