World's Largest Flower Evolved From Family Of Much Tinier Blooms The plant with the world's largest flower -- typically a full meter across, with a bud the size of a basketball -- evolved from a family of plants whose blossoms are nearly all tiny, botanists write this week in the journal Science. Their genetic analysis of rafflesia reveals that it is closely related to a family that includes poinsettias, the trees that produce natural rubber, castor oil plants and the tropical root crop cassava. Endemic Cholera Can Be Controlled With Oral Vaccines, Study Shows Endemic cholera, a potentially fatal diarrheal disease found in the world's most impoverished countries, could be effectively controlled by orally vaccinating half of the affected populations once every two years for only pennies per dose, according to new findings. Youtube for Scientists Regular readers will know that I have a penchant for posting science videos every now and then. I’ve written about vids on how to explain Newton’s laws with Lego, A spoof sweet potato battery to power your mp3 player, Einstein meets Hendrix, and desktop hockey with one of the most water-repellent materials [...] Mysterious Macworld Banners Surface at Moscone New Macworld banners cryptically pronouncing "there's something in the air" started going up Friday at Moscone Center in San Francisco. [Ironic] LONDON: A jailed cocaine dealer is working as Santa Claus on John Tams, who dons beard, boots and red suit to work in a cafe's Christmas grotto, said he wanted to give something back to the community... Another World-record Achievement For National High Magnetic Field Labo The National High Magnetic Field Laboratory in Tallahassee, Fla. is ending its year with another achievement of international importance as engineers and technicians this week completed testing of a world-record magnet. Umbilical Cord Clamping Should Be Delayed,Says Expert Clamping and cutting of the umbilical cord should be delayed for three minutes after birth, particularly for preterm infants, according to a new article. For the mother, trials show that early cord clamping has no ill effects, the doctor writes. But what about the baby? Rapid New Process For Fabricating Microstructures From Protein In an advance in microfabrication technology, scientists report development of a new method for rapidly engineering complex micro-scale patterns and three-dimensional microstructures from biocompatible protein. Humans And Chimps Differ At Level Of Gene Splicing Researchers are closer to understanding why humans differ so greatly from chimpanzees in the way they look, behave, think and fight off disease, despite having genes that are nearly 99 percent identical. Gene Profiling Predicts Resistance To Breast Cancer Drug Herceptin Using gene chips to profile tumors before treatment, researchers at Harvard and Yale Universities found markers that identified breast cancer subtypes resistant to Herceptin, the primary treatment for HER2-positive breast cancer. They say this advance could help further refine therapy for the 25 to 30 percent of breast cancer patients with this class of tumor.
