Purdue scientists see biochemistry's future - with quantum physics
Chemists who have trouble predicting how some large, complex biological molecules will react with others may soon have a solution from the world of computational quantum physics. view more (2005-09-16)
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)
Rocks could reveal secrets of life on Earth - and Mars
A new UK project could help detect evidence for life on Mars, as well as improve our understanding of how it evolved on Earth. The aim is to develop a technique that can identify biomolecules in water that have been trapped in rocks for millions to billions of years. As well as analysing samples from Earth, the proposed technique could be used... view more... (2003-10-09)
Proofreading and error-correction in nanomaterials inspired by nature
Mimicking nature, a procedure developed by researchers at the University of Illinois at Urbana-Champaign can find and correct defects in self-assembled nanomaterials. view more (2005-10-19)
The Nobel Prize in Chemistry 2002
The Nobel Prize in Chemistry is awarded with one half to John B. Fenn and Koichi Tanaka, for their development of methods in mass spectrometry for biomolecules, and with the other half to Kurt Wütrich, for his NMR-method to study biomolecules in solution The Nobel Prize in Chemistry for 2002 is being shared between scientists in two important... view more...

Selecting life: Scientists find new way to search for origin of life
Over the last half century, researchers have found that mineral surfaces may have played critical roles organizing, or activating, molecules that would become essential ingredients to all life-such as amino acids (the building blocks of proteins) and nucleic acids (the essence of DNA). But which of the countless possible combinations of... view more... (2006-11-10)
Scientists learning to create nanomaterials based on micro-algae patterns
Researchers at the Georgia Institute of Technology have developed a technique to study how unicellular micro-algae, known as diatoms, create their complex cell walls. Researchers hope to learn how diatoms assemble these nanometer-patterned, intricate micro-architectures to find better methods for creating nanomaterials in the laboratory. view more (2006-12-07)
Nanoparticles create biocompatible capsules
An innovative strategy of mixing lipids and nanoparticles to produce new drug and agricultural materials and delivery vehicles has been developed by researchers at the University of Illinois at Urbana-Champaign. view more (2006-03-07)
New hypothesis for origin of life proposed
Life may have begun in the protected spaces inside of layers of the mineral mica, in ancient oceans, according to a new hypothesis. view more (2007-12-05)
Researchers uncover new mechanism of tumor suppressor
Researchers from the University of Colorado-Denver and Health Sciences Center and Stanford University have discovered a molecular mechanism that explains how cells respond to DNA damage and other acute stresses, and if disrupted can cause cancer. view more (2006-05-22)
Method devised for diagnosis of ocular diseases
Technological Centre's Area of Biotechnology, together with the Opthtalmological Surgery Clinical Institute of Bilbao (ICQO) are co-operating in a research project the aim of which is to develop a diagnostic system, based on immunochromatographic techniques, for the specific recognition of proteic markers for ocular pathologies in eye teardrop... view more...

Gene-bender proteins may sway to DNA
Among the many genes packed into each cell of our body, those that get turned on, or expressed, are the ones that make us who we are. Certain proteins do the job of regulating gene expression by clasping onto key spots of DNA - the nucleic acid that contains the genetic instructions. view more (2006-12-05)
Water is 'designer fluid' that helps proteins change shape, scientists say
Ubiquitous on Earth, water also has been found in comets, on Mars and in molecular clouds in interstellar space. Now, scientists say this common fluid is not as well understood as we thought. view more (2008-08-07)
Nanoparticles trigger cell death?
Nanoparticles that are one milliard of a metre in size are widely used, for example, in cosmetics and food packaging materials. view more (2008-11-13)
Gold in the realm of dwarves
"Man has been fascinated by gold since ancient times," says a bland introduction to related scientific studies. The fact that there is still room for surprises was shown by a recent publication: Nanoparticles of the precious metal behave differently from those of its close relatives. view more (2004-10-25)
ASU researcher may have discovered key to life before its origin on Earth
An important discovery has been made with respect to the mystery of "handedness" in biomolecules. Researchers led by Sandra Pizzarello, a research professor at Arizona State University, found that some of the possible abiotic precursors to the origin of life on Earth have been shown to carry "handedness" in a larger number than... view more...

Growing green gold
A new way to make gold form inside the cells of a micro-organism is published today in the Institute of Physics journal Nanotechnology. Researchers from the National Chemical Laboratory and the Armed Forces Medical College, both in Pune, India, have been using “green chemistry” to develop an eco-friendly way to make tiny gold particles... view more...

The dynamic personalities of proteins reveal key traits
A Brandeis University study published in Nature this week advances fundamental understanding of the dynamic personalities of proteins and proposes that these enzymes are much more mobile, or plastic, than previously thought. view more (2005-11-04)
ORNL, Protein Discovery researchers collaborate on high-profile paper
A paper that outlines a new method to use a beam of light to trap protein molecules and make them dance in space has earned a place in the Proceedings of the National Academy of Sciences Early Edition. view more (2006-04-13)
LGC selects £500k Bruker Daltonics instrument to expand its mass spectrometry capability
LGC, the UK`s leading independent analytical laboratory providing chemical, biochemical and DNA analysis, has purchased a new Bruker Daltonics APEX III 47e Fourier Transform Mass Spectrometer (FTMS). This instrument, with its exceptionally high mass accuracy and resolution, will be used to characterise high molecular weight materials, especially... view more... (2002-06-10)
