High Aflatoxin Levels In Wild Bird Feed
Wild birdseed contained higher levels of aflatoxins and other mycotoxins than any other kind of pet food analyzed in studies done around the world, a new review of those studies reports in an article scheduled for the Dec. 27 issue of ACS' Journal of Agricultural and Food Chemistry. New Robotic Vehicles Will Hunt For Life And Hydrothermal Vents On Arct
Scientists and engineers have just completed a successful test of new robotic vehicles designed for use beneath the ice of the Arctic Ocean. The researchers will now use those vehicles to conduct the first search for life on the seafloor of the world's most isolated ocean. Does Evolution Select For Faster Evolvers? Horizontal Gene Transfer Ad
A new study suggests the speed of evolution has increased over time because bacteria and viruses constantly exchange transposable chunks of DNA between species, making it possible for life forms to evolve faster than they would if they relied only on sexual selection or random genetic mutation. The Rice University findings come from the first exact solution of a mathematical model of evolution that accounts for cross-species genetic exchange. Imatinib (Gleevec) Has Activity In AIDS-related Kaposi's Sarcoma
A new clinical study has shown that imatinib mesylate (Gleevec) has activity in AIDS-related Kaposi's sarcoma (KS). Imatinib inhibits important pathways that spur cancer growth, resulting in the regression of KS tumors within 4 weeks in some patients. Scientists Unravel How The Brits May Have Struck Gold In Olympic Saili
A study led by UCL (University College London) scientists has unravelled the physical mechanism behind the poorly understood weather phenomenon of coastal wind jets - which are thought to have helped the British sailing team strike gold at the Olympics.
New Screwdriver Can Handle Objects Invisible To The Naked Eye
Manufacturing of products in sizes from a millimeter down to a nanometer is playing an increasing role in the Danish industry. It can be components like screws to be used in hearing aids or in metal devices used for repairing veins. Handling of 3D micro objects like these poses special challenges due to the small absolute scale. In a recent PhD project, a fully automatic screwdriver was designed and manufactured to solve several problems of the assembly process. Safer Method For Large-scale Malaria Screening Developed
Researchers at the Johns Hopkins Bloomberg School of Public Health's Malaria Research Institute have developed a new test for detecting the malaria parasite in human urine and saliva. Although not a diagnostic test for determining treatment, the method could potentially reduce the need for blood sampling in epidemiological studies where large-scale malaria screening is required. Plastic Surgeons Offer Microsurgery Technique For Breast Reconstructio
A new microsurgery by plastic surgeons called the Deep Inferior Epigastric Perforator (DIEP) flap procedure can offer women seeking breast reconstruction after a mastectomy some of the advantages of a more natural breast with the effects of a tummy tuck. Although it is more complex surgery, it preserves muscles for quicker recovery and less postoperative pain, researchers say. Firefighters Keep From Broiling With the Rosenbauer Water-Atomizing No
To avoid getting cremated, firefighters opt for nozzles like the $600 Rosenbauer SelectFlow EN. The SelectFlow's powerful water bore can shoot up to 100 gallons per minute as much as 140 feet away. Backyard Garden May Yield Leukemia Treatment
Scientists here have identified a new pathway in the progression of chronic myelogenous leukemia (CML). They also discovered that an extract from the root of a common ornamental plant can suppress the process. The findings, appearing in the November issue of Cancer Cell, may yield new treatment options for the estimated 4,600 people in the United States who are expected to develop CML this year -- especially those with advanced disease, or those who become resistant to the drug Gleevec.
