New oxidation methods streamline synthesis of important compounds
08-02-2007 · EurekAlert!One of the fundamental challenges facing organic synthesis in the 21st century is the need to significantly increase the efficiency with which carbon frameworks can be constructed and functionalized. Chemists at the University of Illinois are helping to meet this challenge by developing a class of carbon-hydrogen catalysts that are highly selective, reactive and tolerant of other functionality.

- Method Could Help Carbon Nanotubes Become Commercially Viable
10-06-2006 · ScienceDaily
Carbon nanotubes are intriguing new materials, but a fundamental problem relating to their synthesis has limited their widespread commercial use. Current methods for synthesizing the materials produce mixtures of tubes that differ in their diameter and twist. Now Northwestern University researchers have developed a new method for sorting single-walled carbon nanotubes. The method works by exploiting subtle differences in the buoyant densities of carbon nanotubes as a function of their size and electronic behavior.

- New method to directly probe the quantum collisions of individual atoms
04-18-2007 · EurekAlert!
A new method has been developed to directly and precisely measure a quantum property of individual atoms -- the phase shifts that result when they collide at ultracold temperatures -- in a way that is independent of the accuracy-limiting density of the atoms. These shifts, which had been impossible to measure with high precision, are important for atomic clocks and other areas of contemporary atomic physics, including research on super-sensitive atom lasers high-temperature superconductivity.

- Understanding the global carbon budget -- Woods Hole Research Center expert provides insights
05-09-2007 · EurekAlert!
As climate change becomes a more central issue in local, national, and international discussions, understanding the global carbon budget, and how it influences global warming, will become increasingly crucial. One of the world's preeminent carbon experts, Dr. R. A. Houghton, has authored a synthesis paper on the topic, summarizing the global carbon budget and why it is important. The work is featured in the current issue of the Annual Review of Earth and Planetary Science.

- Researchers find best way to detect airborne pathogens
03-21-2007 · EurekAlert!
Current methods used to sniff out dangerous airborne pathogens may wrongly suggest that there is no threat to health when, in reality, there may be. But researchers have found a better method for collecting and analyzing these germs that could give a more accurate assessment of their actual threat. For example, the findings may make it easier to detect airborne pathogens in low concentrations.

- Microarray sequence capture speeds large-scale resequencing of targeted genomic regions
10-14-2007 · EurekAlert!
Researchers at Baylor College of Medicine and Roche NimbleGen Inc. today have published details of a highly efficient and cost-effective method for capturing targeted regions of the genome via NimbleChip microarrays in preparation for high-throughput 454 Sequencing. The technology, called 'sequence capture,' enables fast and accurate enrichment of thousands of selected genomic regions, either contiguous or dispersed, such as segments of chromosomes or all genes or exons. The study appears online in the journal Nature Methods.

- Epigenetic drugs, promising for breast cancer treatment
12-20-2006 · EurekAlert!
Worldwide, cancer persists as one of the most important diseases that affect the human being. The knowledge on the molecular bases of cancer generated during the last decades has been successfully translated into small but significant gains in overall cancer survival rates due to better primary prevention measures, improved diagnostic methods and the development of more effective and specific therapies, collectively termed "molecular targeted therapies." In the context of these new forms of treatment, epigenetic or transcriptional cancer therapy is clearly promising.

- Antwerp artist and brilliant market thinker
09-25-2007 · EurekAlert!
The successful 16th century artist Joos van Cleve from Antwerp had a good working method and a well-considered marketing plan. Dutch art historian Micha Leeflang discovered this during her research at the University of Groningen. Van Cleve worked with a permanent group of assistants, always supplied high quality and targeted important clients as well as the national and international free markets.

- New measure of sexual arousal found for both men and women
02-22-2007 · EurekAlert!
According to a new study published in the latest issue of the Journal of Sexual Medicine and conducted in the Department of Psychology of McGill University, thermography shows great promise as a diagnostic method of measuring sexual arousal. It is less intrusive than currently utilized methods, and is the only available test that requires no physical contact with participants. Thermography is currently the only method that can be used to diagnose sexual health problems in both women and men.

- Burning extra calories with a 'futile protein cycle'
09-04-2007 · EurekAlert!
A new study in the September issue of Cell Metabolism, a publication of Cell Press, points to a new method for burning off all those irresistible extra calories -- by turning on an energy-draining, but otherwise futile, cycle of protein synthesis and breakdown.
