Scientists have studied a visual illusion first discovered by Galileo Galilei, and found that it occurs because of the surprising way our eyes see lightness and darkness in the world. Their results advance our understanding of how our brains are wired for seeing white versus black objects. The work was done by Jens Kremkow and collaborators in the laboratories of Jose Manuel Alonso and Qasim Zaidi at the State University of New York College of Optometry. It will be published on February 10 of...

A better 'mousetrap' discovered in fruit flies might stop a human cancer-driving kinase in its tracks A seemingly obscure gene in the female fruit fly that is only active in cells that will become eggs has led researchers at the Stowers Institute for Medical Research to the discovery of a atypical protein that lures, traps, and inactivates the powerful Polo kinase, widely considered the master regulator of cell division. Its human homolog, Polo-like kinase-1 (Plk1), is misregulated in many...

World-leading experts in Magnetic Resonance Imaging from The University of Nottingham´s Sir Peter Mansfield Magnetic Resonance Centre have made a key discovery which could give the medical world a new tool for the improved diagnosis and monitoring of neuro-degenerative diseases like multiple sclerosis. The new study, published in the Proceedings of the National Academy of Science, reveals why images of the brain produced using the latest MRI techniques are so sensitive to the...

New genome editing technologies developed at the University of Minnesota for use on livestock will allow scientists to learn more about human diseases. The genomic technique, known as TALENS, is described in a report published today in the scientific journal Proceedings of the National Academy of Science. The technique is cheaper and faster than previous technologies that allow scientists to genetically modify livestock animals; the animals are used to learn more about human diseases,...

Protein design is technique that is increasingly valuable to a variety of fields, from biochemistry to therapeutics to materials engineering. University of Pennsylvania chemists have taken this kind of design a step further; using computational methods, they have created the first custom-designed protein crystal. Picking an ambitious design target with challenging features, the researchers´ success bodes well for the technique´s use in better understanding proteins´ makeup...

In a study published in the journal Proceedings of the National Academy of Science, scientists from the Max Planck Institute for Marine Microbiology in Bremen and Greifswald University, together with colleagues from Freiburg, Italy and the USA, have revealed that a small marine worm, faced with a scarce food supply in the sandy sediments it lives in off the coast of Elba, must deal with a highly poisionous menu: this worm lives on carbon monoxide and hydrogen sulphide. The worm, Olavius...

Scientists at the Diabetes Research Institute have developed a revolutionary technique to provide critical oxygen for maintaining the survival of insulin-producing cells. This is the first time that scientists have been able to successfully deliver oxygen locally to beta cells using a biomaterial. The results of the study, which represents a major step toward the goal of developing an alternative site to house insulin-producing cells, were just published in the prestigious journal Proceedings...

Study may aid in development of improved therapies for glioblastoma A recent discovery by Van Andel Research Institute (VARI) scientists enables the prediction of patient sensitivity to proposed drug therapies for glioblastoma — the most common and most aggressive malignant brain tumor in humans. The study, published in January in the Proceedings of the National Academy of Science, investigated glioblastoma models characterized by cell signaling activation and gene amplification...

[ Watch the Video ] Test is based on the difficulty that these parkinsonian C. elegans worms have in switching from swimming to crawling Researchers at The University of Texas at Austin have devised a simple test, using dopamine-deficient worms, for identifying drugs that may help people with Parkinson's disease. The worms are able to evaluate as many as 1,000 potential drugs a year. The researchers have received federal funding that could increase that to one million drug tests a...
