Syracuse University researchers discover new way to attack some forms of leukemia
Each year, some 29,000 adults and 2,000 children are diagnosed with leukemia, a form of cancer that is caused by the abnormal production of white blood cells in the bone marrow. Current treatments rely primarily on killing the cancer cells, which also destroys normal cells. But what if a way could...
As Andean glacier retreats, tiny life forms swiftly move in, CU-Boulder study shows
A University of Colorado at Boulder team working at 16,400 feet in the Peruvian Andes has discovered how barren soils uncovered by retreating glacier ice can swiftly establish a thriving community of microbes, setting the table for lichens, mosses and alpine plants.
The discovery is the first t...
Lab study shows methadone breaks resistance in untreatable forms of leukemia

Creating new life forms that may help eradicate cancer affecting women
Instead of using the usual cancer-fighting modalities, surgery, chemotherapy, or radiation, researchers from a drug development company called Advaxis, have embarked on a novel approach to fighting cancer: Engaging the immune system to attack cancer in the same the way it would a flu vaccine, by cr...
How the octopus forms an elbow
The octopus arm is extremely flexible. Thanks to this flexibility--the arm is said to possess a virtually infinite number of "degrees of freedom"--the octopus is able to generate a vast repertoire of movements that is unmatched by the human arm. Nonetheless, despite the huge evolutionary gap and mo...
