Using yeast to identify cancer genes

Researchers use yeast to identify cancer-causing genes that may also occur in humans

31-Jul-2009 - Identifying cancer-causing genes is a major challenge, but now Cornell scientists have devised a technique using yeast cells to identify new cancer genes that may also be found in humans. The study, published in Public Library of Science Biology, is the first to report on mutations in yeast that ...

Mapping the crocodile genome

30-Jul-2009 - The first ever genetic linkage map for a non-avian member of the Class Reptilia has been developed. Researchers writing in BMC Genomics have constructed a first-generation genetic linkage map for the saltwater crocodile Crocodylus porosus. Dr Lee Miles, from the University of Sydney, worked with ...

Icy exposure creates armored polymer high tech foams

30-Jul-2009 - Chemists and engineers at the University of Warwick have found that exposing particular mixtures of polymer particles and other materials to sudden freeze-drying can create a high-tech armored foam that could be used for a number of purposes, including a new range of low power room temperature ...

New method uses electrolyzed water for more efficient fuel production

29-Jul-2009 - Using electrolyzed water rather than harsh chemicals could be a more effective and environmentally friendly method in the pretreatment of ethanol waste products to produce an acetone-butanol-ethanol fuel mix, according to research conducted at the University of Illinois. When ethanol is ...

Researchers develop 'brain-reading' methods

Rutgers research discovery sets direction for decoding large-scale structure of brain

29-Jul-2009 - It is widely known that the brain perceives information before it reaches a person's awareness. But until now, there was little way to determine what specific mental tasks were taking place prior to the point of conscious awareness. That has changed with the findings of scientists at Rutgers ...

Scientists closer to making implantable bone material, thanks to new research

28-Jul-2009 - Scientists are closer to understanding how to grow replacement bones with stem cell technology, thanks to research published in the journal Nature Materials. Many scientists are currently trying to create bone-like materials, derived from stem cells, to implant into patients who have damaged or ...

Caltech physicists create first nanoscale mass spectrometer

Device can instantly measure the mass of an individual molecule

27-Jul-2009 - Using devices millionths of a meter in size, physicists at the California Institute of Technology (Caltech) have developed a technique to determine the mass of a single molecule, in real time. The mass of molecules is traditionally measured using mass spectrometry, in which samples consisting of ...

Music is the engine of new U-M lab-on-a-chip device

27-Jul-2009 - Music, rather than electromechanical valves, can drive experimental samples through a lab-on-a-chip in a new system developed at the University of Michigan. This development could significantly simplify the process of conducting experiments in microfluidic devices. A lab-on-a-chip, or ...

Carbon nanotubes and aptamers: New biosensor detects extremely low bacteria concentrations quickly, easily and reliably

23-Jul-2009 - Bacterial diseases are usually detected by first enriching samples, then separating, identifying, and counting the bacteria. This type of procedure usually takes at least two days after arrival of the sample in the laboratory. Tests that work faster, in the field, and without complex sample ...

NYU physicists find way to explore microscopic systems through holographic video

23-Jul-2009 - Physicists at New York University have developed a technique to record three-dimensional movies of microscopic systems, such as biological molecules, through holographic video. The work, which is reported in Optics Express, has potential to improve medical diagnostics and drug discovery. The ...
