New Light Cast On Key Chemical Reactions In Interstellar Space
A detailed understanding of key chemical reactions that take place in interstellar space has been provided by new research. Scientists have developed a detailed understanding of the dynamics of reactions between neutral radicals and neutral molecules, known as ?neutral-neutral?reactions, at temperatures as low as 20 Kelvin, approximately the temperature of interstellar space. Gore's Webby TV Network Debuts
Current TV, the channel Al Gore and his cohorts bought, launches Monday. Its utopian vision of being the sounding board for young people and broadcasting content produced by viewers will have to prove profitable. Neural Stem Cell Study Reveals Mechanism That May Play Role In Cancer
In the dynamic world of the developing brain, neural stem cells give rise to neurons deep within the brain's fluid-filled ventricles. These newborn neurons then migrate along the stem cell fibers up to the neocortex, the seat of higher cognitive functions. Now, scientists have discovered a key mechanism of this migration -- one that may also play an important role in other developmental processes and diseases, including cancer. Ocean acidification: 'Evil twin' threatens world's oceans, scientists
The rise in human emissions of carbon dioxide is driving fundamental and dangerous changes in the chemistry and ecosystems of the world's oceans, marine scientists warn. "Ocean conditions are already more extreme than those experienced by marine organisms and ecosystems for millions of years," the researchers say. Solving The Mystery Of Mutated Proteins And The Brain
In some neurological diseases, too much of what is usually a good thing can be bad, said researchers at Baylor College of Medicine in a report in this week's issue of the journal Cell.Dr. Huda Zoghbi and her colleagues have determined that a genetic mutation actually enhances the normal activity of a protein, and in the case of ataxin-1, the disease spinocerebellar ataxia type 1 results. Brit Film Future Is Digital
The U.K. Film Council wants to encourage people to see more specialty films and thinks installing high-tech projectors is the way to do it. By Jason Silverman. New Research Shows How Evolution Explains Age Of Puberty
Children aged 10 and 11 are sexually mature, and neither they nor society are suitably prepared for the implications of that. This is the message of Professors Mark Hanson and Peter Gluckman, whose review of the evolution of puberty is published online this week in Trends in Endocrinology and Metabolism. 'Real Life' Study Clarifies Risk Of Recurrence For High-risk Breast Ca
High-risk breast cancer patients do not appear to have a higher risk of relapse than the general breast cancer population during the first two years after diagnosis, unless their cancer has spread to more than 10 axillary lymph nodes, Italian researchers reported today at the 2nd ESMO Scientific &Educational Conference (ESEC) in Budapest, Hungary. What Recognizes What In Plant Disease Resistance?
How do plant resistance gene recognize the cognate pathogen? These authors dissect the interaction of a resistance gene and a viral pathogen. New Technology Shows Our Ancestors Ate ... Everything!
Using a powerful microscope and computer software, a team of scientists from Johns Hopkins, the University of Arkansas, Worcester Polytechnic Institute and elsewhere has developed a faster and more objective way to examine the surfaces of fossilized teeth, a practice used to figure out the diets of our early ancestors.
