Superfluid Helium-4 Whistles Just The Right Tune
University of California, Berkeley, physicists can now tune in to and hear normally inaudible quantum vibrations, called quantum whistles, enabling them to build very sensitive detectors of rotation or very precise gyroscopes. 'Audioclouds' That Will Help Us Compute More Safely On The Move
New research by UK scientists that enables people to interact safely with mobile computers while walking, running or driving, could help to prevent users from putting themselves in danger. Researchers Identify Genes That Foster Blood Cell Development From Ste
For a child with leukemia or lymphoma, a donation of umbilical cord blood can be a lifesaver. Now, University of Minnesota researchers have identified a group of genes that guide the functioning of hematopoietic stem cells, a finding that may help researchers grow enough of the cells in the laboratory to give doctors more options in treating patients. Ways To Teach Approved Drugs New Tricks: How To Combat Cancer
Although all cancers are not alike, most share common causes, whether it is the result of a genetic mutation or faulty biochemical signaling pathway. For that reason, drugs developed specifically for one disease might have an impact on many others. Increasingly, researchers are discovering ways of combining new and existing drugs to fight cancer -- broadening the targets of already-approved targeted therapeutics. NASA/French Satellite Data Reveal New Details Of Tsunami
For the first time, orbiting satellites have observed and measured a major tsunami event in open ocean, the Indian Ocean tsunami that resulted from the magnitude 9 earthquake southwest of Sumatra on December 26. The measurements are of tremendous value to researchers worldwide and will aid our understanding of these events. The Seoul of a New Machine
Korean robotics researchers develop ghostly software agents that move from one droid to another, taking possession of their mechanical bodies long enough to perform a task, before vanishing into the ether. Quinn Norton reports from Daejeon, Korea. New Method For Detecting Fake Drugs Without Opening The Package
With sale of counterfeit drugs causing major problems around the world, scientists in the United Kingdom are reporting development of a new way of identifying fake pills and capsules without opening the product package. In a report scheduled for the March 1 issue of ACS' Analytical Chemistry, a semi-monthly journal, Pavel Matousek and Charlotte Eliasson describe the growing need for non-invasive verification of the authenticity of pharmaceutical products. How Is Asthma Related To Chronic Obstructive Pulmonary Disease?
Two new studies exploring the causes and treatment of asthma and chronic obstructive pulmonary disease could lead to the development of drugs to battle these debilitating conditions. Ancient Fossil Evidence Supports Carbon Dioxide As Driver Of Global Wa
A new way to study Earth's past climate by analyzing the chemical composition of ancient marine fossils has been devised. The first published tests with the method further support the view that atmospheric carbon dioxide has contributed to dramatic climate variations in the past, and strengthen projections that human carbon dioxide emissions could cause global warming. Diet And Lifestyle Changes May Help Prevent Infertility From Ovulatory
Women who followed a combination of five or more lifestyle factors, including changing specific aspects of their diets, experienced more than 80 percent less relative risk of infertility due to ovulatory disorders compared to women who engaged in none of the factors, according to an article in Obstetrics &Gynecology.
