Melvyn shows how small molecules could help crack a big problem Chemistry undergraduate Melvyn Ansell's JRA project looked at small molecules to help solve one of the world's biggest problems - the environmental impact of CO2 emissions. The chemistry department at the University of Sussex is currently conducting research into clean fuels technology, looking at ways that greenhouse gases can be manipulated (eg conversion of CO2to other molecules) to mitigate their effect on global warming.

Getting (drugs) under your skin
Using ultrasound waves, MIT engineers have found a way to enhance the permeability of skin to drugs, making transdermal drug delivery more efficient. This technology could pave the way for noninvasive drug delivery or needle-free vaccinations, according to the researchers. "This could be used for topical drugs such as steroids - cortisol, for example - systemic drugs and proteins such as insulin, as well as antigens for vaccination, among many other things," says Carl Schoellhammer, an MIT graduate student in chemical engineering and one of the lead authors of a recent paper on the new system.

Measuring mercury levels: Nano-velcro detects water-borne toxic metals
Measuring mercury levels: Nano-velcro detects water-borne toxic metals
ANN ARBOR, Mich.-A strip of glass covered in hairy nanoparticles can cheaply and conveniently measure mercury, which attacks the nervous system, and other toxic metals in fluids. Researchers at the Swiss Federal Institute of Technology (EPFL), Northwestern University and the University of Michigan found that their new method can measure methyl mercury, the most common form of mercury pollution, at unprecedentedly small concentrations.

Employees at 'green' companies are significantly more productive, study finds
Employees at ’green’ companies are significantly more productive, study finds
Bucking the idea that environmentalism hurts economic performance, a new UCLA-led study has found that companies that voluntarily adopt international "green" practices and standards have employees who are 16 percent more productive than the average. Professor Magali Delmas, an environmental economist at UCLA's Institute of the Environment and Sustainability and the UCLA Anderson School of Management , and Sanja Pekovic from France's University Paris-Dauphine are the first to study how a firm's environmental commitment affects its productivity.

Proteins barge in to turn off unneeded genes and save energy
Proteins barge in to turn off unneeded genes and save energy
The sorcerer's apprentice started a water-carrying system, but couldn't stop it, and soon he was up to his neck in water, and trouble. Living cells have a better design: When they activate a gene, they have a system in reserve to turn it off. The cell does not want to waste energy making proteins it no longer needs.

Interfaces provide new control over oxides' electronic properties
Interfaces provide new control over oxides’ electronic properties
Materials called transition metal oxides have physicists intrigued by their potentially useful properties - from magnetoresistance (the reason a hard drive can write memory) to superconductivity. By combining two sophisticated experimental tools - oxide molecular beam expitaxy and angle-resolved photoemission spectroscopy - researchers have gained the first insights into quantum interactions in transition metal oxide superlattices, which are artificial stacked layers of alternating materials, each just a few atoms thick.

Organic farms not necessarily better for environment
Organic farming is generally good for wildlife but does not necessarily have lower overall environmental impacts than conventional farming, a new analysis led by Oxford University scientists has shown. The researchers analysed data from 71 studies published in peer-reviewed journals that compared organic and conventional farms in Europe.

The Quantum World Only Partially Melts
At the Vienna University of Technology, the transition of quantum systems towards thermal equilibrium has been investigated. Scientists have detected an astonishingly stable intermediate state between order and disorder. The results have now been published in the journal "Science". Every day we observe systems thermalizing: Ice cubes in a pot of hot water will melt and will never remain stable.

Showing the Way to Improved Water-Splitting Catalysts
Showing the Way to Improved Water-Splitting Catalysts
Scientists and engineers around the world are working to find a way to power the planet using solar-powered fuel cells. Such green systems would split water during daylight hours, generating hydrogen (H2) that could then be stored and used later to produce water and electricity. But robust catalysts are needed to drive the water-splitting reaction.

Metabolism in the brain fluctuates with circadian rhythm
Metabolism in the brain fluctuates with circadian rhythm
CHAMPAIGN, lll. The rhythm of life is driven by the cycles of day and night, and most organisms carry in their cells a common, (roughly) 24-hour beat. In animals, this rhythm emerges from a tiny brain structure called the suprachiasmatic nucleus (SCN) in the hypothalamus. Take it out of the brain and keep it alive in a lab dish and this "brain clock" will keep on ticking, ramping up or gearing down production of certain proteins at specific times of the day, day after day.

New method helps researchers decode genomes
New method helps researchers decode genomes
Although scientists sequenced the entire human genome more than 10 years ago, much work remains to understand what proteins all those genes code for. Now, a study published online Aug. 27 in the Proceedings of the National Academy of Sciences describes a new approach that allows researchers to decode the genome by understanding where genes begin to encode for polypeptides, long chains of amino acids that make up proteins.

Weighing Molecules One at a Time
Weighing Molecules One at a Time
A team led by scientists at the California Institute of Technology (Caltech) has made the first-ever mechanical device that can measure the mass of individual molecules one at a time. This new technology, the researchers say, will eventually help doctors diagnose diseases, enable biologists to study viruses and probe the molecular machinery of cells, and even allow scientists to better measure nanoparticles and air pollution.

Form, Function and Folding: In collaboration with Berkeley Lab, a team of scientists move toward rational design of artificial proteins
Form, Function and Folding: In collaboration with Berkeley Lab, a team of scientists move toward rational design of artificial proteins
In the world of proteins, form defines function. Based on interactions between their constituent amino acids, proteins form specific conformations, folding and twisting into distinct, chemically directed shapes. The resulting structure dictates the proteins' actions; thus accurate modeling of structure is vital to understanding functionality.
