The Ultimate Spa: Embryonic Body Wash Controls Left-right Development
Humans and other animals may appear to be symmetrical on the outside, but symmetry is only skin deep. Many body organs, such as the stomach, the heart and the liver, are tipped to the right or left side. So how does the developing embryo distinguish left from right? Salk scientists have now discovered that the foundations for the basic left-right body plan are laid by a microscopic 'pump' on the outer surface of the embryo's underside that wafts chemical messengers over to the left side of the body. Some Tropical Birds Depend Completely On Army Ants To Flush Out Prey
In the jungles of Central and South America, a group of birds has evolved a unique way of finding food -- by following hordes of army ants and letting them do all the work. Some of the birds rely solely one species of army ant. Brumfield pointed out that, "This makes the professional army-ant followers sensitive to many of the very real threats to this ecosystem, like deforestation, global warming and other similar issues. If anything affects the ant population, it could be devastating for these birds. But what is perhaps most surprising is that, despite the bird's dependence on one primary ant species, the specialization has persisted for millions of years." Painless Test Using Teardrops May Speed Diagnosis Of Sjögren's Syndrom
Researchers in Japan are developing a faster, more accurate diagnostic test for Sjögren's (SHOW-grins) syndrome, an incurable autoimmune disorder characterized by chronically dry eyes and dry mouth. The noninvasive test, which analyzes multiple protein biomarkers in the tears using highly sensitive mass spectrometry, shows promise in early clinical studies as the first simple test for identifying the disease, the scientists say. Proteins As Parents: Recombining Parts Yields New Mechanical Propertie
A team from the University of British Columbia succeeded in producing proteins with new mechanical properties through the combination of two "parent"protein fragments. Most Powerful Group Of Microscopes In The World
Seven new super-microscopes and a specially designed building will give scientists unique opportunities to design new materials. Among the areas that will benefit are the environment, manufacturing, energy and transport. One of the total of seven new microscopes is the almost four-metre-high 'Environmental Transmission Electron Microscope', developed in association with DTU by world-leading microscope manufacturer FEI Company. It is the most powerful of its type in the world. Surface Orbital 'Roughness'In Manganites Discovered
Researchers have shown that in a class of materials called manganites, the electronic behavior at the surface is considerably different from that found in the bulk. Their findings could have implications for the next generation of electronic devices, which will involve increasingly smaller components. Bacteria-based Production Method Patented
Look on a package of gum and you'll probably notice the word mannitol. Scientifically described as a sugar alcohol, mannitol is a minty-tasting ingredient found in many foods and boasts fewer calories than table sugar. Now, the Agricultural Research Service (ARS) obtained a patent (US 6,855,526, B2) on a method that weds nature with modern technology. Better Births Feature Continuous Care For Moms, 'Kangaroo'Care For Kid
When it comes to giving birth, some traditional approaches could result in happier and healthier moms and newborns, according to two research reviews. Women who have a midwife, doula or a supportive family member with them throughout labor are more likely to have a shorter labor, less likely to use painkillers during labor and more likely to be satisfied with their childbirth experience, compared to those who receive regular hospital care. United Nations History: 60th Anniversary of the San Francisco Conferen
"In celebration of the United Nations sixtieth anniversary [in 2005], the United Nations Department of Public Information has organized a commemoration of the signing of the United Nations Charter, which took place in San Francisco on 26 June 1945."The site includes the message of the Secretary-General, a video clip, and a list of exhibits and activities commemorating the event. Also includes links to information about the 50th anniversary and to related documents. Building Disease-beating Wheat
Disease resistance genes from three different grass species have been combined in the world's first "trigenomic"chromosome, which can now be used to breed disease resistant wheat varieties.
