New advances may slow tumor growth in pancreatic cancer
...kens the process to a scorpion that not only has a newfound immunity to his own poison, but every time he stings himself, he gets bigger and more powerful. "Now that we know how Smad7 is able to inactivate TGF-beta growth suppressive effects by preventing RB from functioning properly, we can focus our rese...Where China goes, the rest follow in the global neighborhood
...it a small world, after all, and the costs of this newfound neighborliness are high. Two internationally acclaimed scientists present sweeping evidence that China's challenges from polluted air and water to making and consuming goods to family life already are making a big impact on the environment and hum...Discovering an ecosystem beneath a collapsed Antarctic ice shelf
...ment deposition. In addition, he suggests that the newfound system may provide incentive to launch studies to other remote undersea environments in the poles and in other glacial settings such as Lake Vostok, also in the Antarctic, to further explore the little-understood connection where ice sheets, the seaf...Brain activity in youth may presage Alzheimer's pathology
...e metabolic consequences," Buckner explained. The newfound correlation may also have future clinical implications as Alzheimer's is typically diagnosed when it is too late to intervene. To develop and administer effective treatments, clinicians will need to figure out ways to detect the disease in its earlie...Global signaling study suggests cancer link to protein promiscuity
...ir high oncogenic potential," MacBeath says. "This newfound link may also offer alternative strategies for therapeutic intervention. Many of today's cancer pharmaceuticals work by targeting individual receptors such as EGFR and ErbB2. Our work suggests that new drugs could target critical secondary pathways t...Worm hormone discovery may aid fight against parasitic disease
...in C. elegans. Like a key fitting into a lock, the newfound ligand binds to a protein in the cell's nucleus called a nuclear receptor, a receptor designated DAF-12. Once that binding occurs, DAF-12 activates other genes that allow the worm to develop through its normal stages, reach maturity and reproduce. W...Iron critical to ocean productivity, carbon uptake
...opical Pacific centered on the equator. With their newfound knowledge of fluorescence, the scientists believe they now can use satellite imagery to identify specific areas that are iron-stressed and how they respond to changes such as the sudden influx of iron from a windstorm. "It turns out different places...Shotgun sequencing finds nanoorganisms
...of Science. Banfield noted that the bacteria and newfound Archaea living in the highly acidic mine drainage are archetypes of the kind of life that could exist on other planets, such as in the iron- and sulfur-rich soil of Mars. "This community of microbes is relevant to probing potential strategies for l...Iowa State University botanists identify new species of North American bamboo

Following rules laid out in the International Code of Botanical Nomenclature, they prepared a short description of the plant in Latin and a longer one in English, and provided drawings and other information to make a strong case for the reco...Blood's clotting cells harbor 'ticking time bombs,' finding may help extend blood supply

However, the researchers added, the side effect is likely to be self-limiting as normal bone marrow has the capacity to compensate by increased platelet product...National Academy of Sciences elects 2 Rutgers professors
...Falkowski said. "I look forward to working with my newfound colleagues in the NAS to serve our national science needs. On a personal level, I will continue to work on understanding the evolution of biogeochemical cycles, and their role in making the world habitable for humans." Falkowski is an international...Global heartbeat control suggests therapy for beating heart failure
...ull all of the strings. Drugs that influence these newfound global orchestrators of heart function might offer a novel approach to managing diseases of the heart muscle, according to the researchers. "The heart is a simple pumping organ," said Vincent Giguere of McGill University in Montreal. "What it needs...From ink to optics, study of particle mixtures yields fundamental insights

With the newfound ability to calculate accurate phase diagrams, researchers may be able to improve the fabrication of artificial opal crystals -- colloids essential for high-speed transmission of data given the way in which they diffract optical signals.
