(PhysOrg.com) -- Even if you are not a cook, you might have wondered why a pinch of flour (or any small particles) thrown into a bowl of water will disperse in a dramatic fashion, radiating outward as if it was exploding. Pushpendra Singh, PhD, a mechanical engineering professor at NJIT who has studied and written about the phenomenon, has not only thought about it, but can explain why. http://www.physorg.com/news177616622.html Physics Mon, 16 Nov 2009 18:30:05 EST news177616622 (PhysOrg.com) -- Computer scientists have spent decades developing techniques for answering a single question: How long does a given calculation take to perform? Constantinos Daskalakis, an assistant professor in MIT`s Computer Science and Artificial Intelligence Laboratory, has exported those techniques to game theory, a branch of mathematics with applications in economics, traffic management -- on both the Internet and the interstate -- and biology, among other things. By showing that some common game-theoretical problems are so hard that they`d take the lifetime of the universe to solve, Daskalakis is suggesting that they can`t accurately represent what happens in the real world. http://www.physorg.com/news176978473.html Technology Mon, 09 Nov 2009 09:20:01 EST news176978473 (PhysOrg.com) -- Diverting sediment-rich water from the Mississippi River below New Orleans could generate new land in the river's delta in the next century. http://www.physorg.com/news175276001.html Space & Earth Tue, 20 Oct 2009 17:10:01 EST news175276001 Our brains, it turns out, are eco-friendly. A study published in Science and reviewed by F1000 Biology members Venkatesh Murthy and Jakob Sorensen reveals that our brains have the amazing ability to be energy efficient. http://www.physorg.com/news174738260.html Medicine & Health Wed, 14 Oct 2009 11:50:01 EST news174738260 (PhysOrg.com) -- October ushers in the fourth quarter, falling leaves, football and in some, now infamous, years, financial meltdowns. Is the tenth month of the year more prone to stock market crashes than others? Economics professor Stephen Williamson says there's little evidence to support that the next big crash will occur this month just because the last three major crashes happened in October. http://www.physorg.com/news173986149.html Other Sciences Mon, 05 Oct 2009 18:40:01 EST news173986149 Osteoporosis, or bone loss, is a disease that is most common in the elderly population, affecting women more often than men. Until now, it was not clear exactly how the disease develops. Researchers of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have now elucidated a molecular mechanism which regulates the equilibrium between bone formation and bone resorption. Dr. Jeske J. Smink, Dr. Valérie Bégay, and Professor Achim Leutz were able to show that two different forms of a gene switch - a short isoform and a long isoform - determine this process. The MDC researchers hope these findings will lead to new therapies for this bone disease. http://www.physorg.com/news161528731.html Medicine & Health Thu, 14 May 2009 14:05:49 EST news161528731 (PhysOrg.com) -- A North Carolina State University paleontologist has more evidence that soft tissues and original proteins can be preserved over time - even in fossilized remains - in the form of new protein sequence data from an 80 million-year-old hadrosaur, or duck-billed dinosaur. http://www.physorg.com/news160320581.html Other Sciences Thu, 30 Apr 2009 14:30:22 EST news160320581 (PhysOrg.com) -- The nanobubbles that develop on submerged surfaces should not really be able to exist. Because of the enormous internal pressure, they should disappear within a short time. Nevertheless, they sometimes last for hours: an unexplained phenomenon. http://www.physorg.com/news147454736.html Nanotechnology Tue, 02 Dec 2008 15:38:56 EST news147454736
