Nanoparticles Offer New Hope For Detection And Treatment
Specially designed nanoparticles can reveal tiny cancerous tumors that are invisible to ordinary means of detection, according to a study by researchers at Washington University School of Medicine in St. Louis. Researchers demonstrated that very small human melanoma tumors growing in mice -- indiscernible from the surrounding tissue by direct MRI scan -- could be "lit up"and easily located. Because the nanoparticles can be engineered to carry a variety of substances, they also may be able to deliver cancer-fighting drugs to malignant tumors. Natural Anti-viral Enzyme Helps Keep Cancer Cells Alive, Researchers F
A molecule that cells normally use to fight viruses is also involved in keeping cancer cells alive, researchers at UT Southwestern Medical Center have discovered. [Ironic] An Italian pensioner committed suicide after his wife fell in
Recalling the end of Romeo and Juliet, the 70-year-old man, Ettore, who had sat by his wife's bedside for four months after she slipped into a coma following a heart attack, finally gave up hope and gassed himself in the garage of his family home.Less than a day later, his wife, Rossana, woke up in her hospital bed in Padua and immediately asked for him. Which Came First, The Moth Or The Cactus?
It's not a good idea to put all your eggs in one basket -- unless you're a senita moth. Found in the parched Sonoran desert, the moths have a rare, mutually dependent relationship with senita cacti, one of only three known dependencies in which an insect actively pollinates flowers for the purpose of assuring a food resource for its offspring. Ecologists are using the relationship to test new theories of community ecology. Mechanism Of Gene Linked To Autism, Schizophrenia Pinpointed
A researcher has pinpointed the mechanism by which a gene associated with both autism and schizophrenia influences behavior in mice. Purdue Method To Help Engineers Design Systems For Mars, Moon Missions
Purdue University researchers, in the culmination of a four-year NASA-funded project, have created a method that will enable engineers to design more efficient systems for heating, cooling and other applications in spacecraft for missions to Mars and the moon. Siberian Fires Most Common Near People
While Siberia may be one of the last expanses on Earth where human presence is relatively scarce, scientists are finding some surprising connections between humans and fires in these frigid, northern forests. Until now, most researchers assumed that lightning caused most of the fires that burned in Siberia. Dead On Target: Nanoparticle Seeks Out And Binds WIth Cancer Cells
Researchers have devised dendrimer nanoparticle systems which are able to seek out and specifically bind to cancer cells. Scientists have designed dendrimer nanoparticle systems that are stable, water soluble, and biocompatible. War On Terror Meets War On Cancer
A scientific method that has been used to track the source of illegal drugs, explosives, counterfeit bills and biological warfare agents may have some new uses: detecting rapidly growing cancers and studying obesity and eating disorders. Those uses may result from a new study that challenges the long-held belief that the water inside cells is chemically identical to the water outside cells. Key Found To Moonlight Romance On The Reef
Researchers have discovered what could be the aphrodisiac for the biggest moonlight sex event on Earth. An ancient light-sensitive gene has been isolated that appears to act as a trigger for the annual mass spawning of corals across a third of a million square kilometres of Australia?s Great Barrier Reef, shortly after a full moon. The genes occur in corals, insects, fish and mammals - including humans - and are primitive light-sensing pigment mechanisms which predate the evolution of eyes.
