Researchers at the National Institute of Standards and Technology (NIST) have made the first confirmed "spintronic" device incorporating organic molecules, a potentially superior approach for innovative electronics that rely on the spin, and associated magnetic orientation, of electrons.   view more (2006-10-13)

Scientists at VTT and the University of Florida take immunotechnology to a new level
Scientists at VTT and the University of Florida take immunotechnology to a new level Mimicking the cell walls transport system by biocoated nanotubes opens novel possibilities for numerous applications Living cells transport selectively molecules in and out through their cell walls. This process... view more (2002-07-04)

Nature inspires new highly specific drugs and organic products
The best place to seek novel compounds for pharmaceutical drugs, alternative energy sources, and a host of industrial applications, is within natural systems that have evolved over millions of years.   view more (2008-09-03)

Solution to elusive problem
Scientists at the University of Leicester are on the way to solving a problem that has long beset chemists trying to study chemical reactions. To establish reaction mechanisms the observation of reaction intermediates is vital, but they are incredibly short-lived under normal conditions, and... view more (2003-01-21)

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)

Scientists set out to measure how we perceive naturalness
Natural products are highly valued by consumers yet their properties have been difficult to reproduce fully in synthetic materials, placing a drain on our limited natural resources. Until now ...   view more (2008-07-07)

Two suppressor molecules affect 70 genes in leukemia
By restoring two small molecules that are often lost in chronic leukemia, researchers were able to block tumor growth in an animal model.   view more (2008-04-25)

Inflammation may cause preterm labor and fetal deaths
Inflammation from bacterial infections is linked to preterm births and deaths, according to researchers from Case Western Reserve University's School of Dental Medicine and the Case School of Medicine.   view more (2007-08-09)

Plastic-Protein Hybrid Materials
Enzymatic films for bioactive surfaces We encounter them every day in laundry detergent, dishwashing liquid, or shower gel: surfactants - surface-active substances. Surfactants belong to a category of molecules called amphiphiles, molecular hermaphrodites consisting of a water-loving (hydrophilic)... view more (2001-12-21)

Research could help finger more criminals
Scientists at the University of Sunderland are working on new technology that could help police forces catch criminals, by providing more clear and detailed fingerprints. Researchers at the university's School of Health, Natural & Social Sciences are developing what's known as a nanoparticle... view more (2003-11-14)

An obstacle to cancer cells
The circulation of cancer cells through the blood vessels is often the cause of metastasis. These cancer cells contaminate normal cells and the pathology spreads throughout the body.   view more (2005-12-19)

Measurements may help show if constants are changing
Physicists at JILA have performed the first-ever precision measurements using ultracold molecules, in work that may help solve a long-standing scientific mystery-whether so-called constants of nature have changed since the dawn of the universe.   view more (2006-05-01)

New reagent delivers a chemical breakthrough at FSU
"Build a better mousetrap," the saying goes, "and the world will beat a path to your door." In the complex field of organic chemistry, that path leads to Florida State University, where a newly developed substance could make the jobs of scientists throughout the world a little... view more (2007-03-16)

Cellular pathway yields potential new weapon in vaccine arsenal
When a cell has to destroy any of its organelles or protein aggregates, it envelopes them in a membrane, forming an autophagosome, and then moves them to another compartment, the lysosome, for digestion. Two years ago, Rockefeller University assistant professor Christian Münz showed that this... view more (2006-12-27)

New possibilities for drug design
An article in Journal of Physics B, published on 7 July 2003 by the Institute of Physics, reports on a new technique which could in future help scientists working in rational drug design (a way of tailoring a new drug to fit the structure of the protein it targets) to develop drugs more... view more (2003-07-04)

'Micro-boxes' of water used to study single molecules
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated the use of water droplets as minuscule "boxes" for small numbers of biomolecules.   view more (2006-07-24)

A Morse code for human cells
Morse code is a simple, effective and clear method of communication and now scientists believe that cells in our body may also be using patterns of signals to switch genes on and off. The discovery may have major implications for the pharmaceutical industry as the signalling molecules that are... view more (2005-01-06)

Model for the assembly of advanced, single-molecule-based electronic components developed at Pitt
Researchers based at the University of Pittsburgh have created the best method so far of assembling wire-like structures only a single molecule wide, a significant step in science's increasing attempts to reduce the circuitry size of electronic devices to the single molecule scale and provide... view more (2007-09-27)

UIC and Japanese chemists close in on molecular switch
The electronics industry believes that when it comes to circuits, smaller is better -- and many foresee a future where electrical switches and circuits will be as tiny as single molecules.   view more (2007-07-11)

Thyroid-cancer test reveals recurrence early
A blood test for thyroid cancer can detect persistent or recurrent disease even before doctors can find any trace of a tumor, according to a new study. The findings suggest that people treated for the disease should be examined regularly for early signs of recurrence.   view more (2005-06-27)
