In the 1990s, life was simpler for environmentalists. Crippling the logging industry was all that was needed to protect trees and birds.
But, as in abortion or gun control, you have to sue everyone or you can sue no one and even responsible logging and clearing brush was stopped by environmental lawsuits and as a result, wildfires have become far more frequent and far more devastating. Now add a new wrinkle - no logging is leading to more global warming.
NASA's Inflatable Reentry Vehicle Experiment (IRVE-3), a large inflatable heat shield developed, was launched by sounding rocket at 7:01 a.m. Monday from NASA's Wallops Flight Facility on Wallops Island, Va. It successfully survived a trip through Earth's atmosphere while traveling at hypersonic speeds of 7,600 mph.
At the time of diagnosis, hundreds of mutations already exist in leukemia cells but new research has found they are a part of normal aging and are not related to cancer.
Even in healthy people, stem cells in the blood routinely accumulate new mutations over the course of a person’s lifetime. In many cases only two or three additional genetic changes are required to transform a normal blood cell already dotted with mutations into acute myeloid leukemia (AML).
Researchers have linked mutations in specific genes to each of the four recognized subtypes of medulloblastoma, the most common malignant brain tumor of children. The discovery provides doctors with potential biomarkers for guiding and individualizing treatment and reveals prospective therapeutic opportunities for countering this devastating malignancy.
Medulloblastomas occur in the cerebellum, the part of the brain that controls balance and other complex motor functions, and are treated with a combination of surgery, radiation and chemotherapy. Though overall survival hovers around 70 percent, most survivors are unable to live independently due to the lasting effects of both tumor and treatment.
Could a new bag squash a new bug?
A new medical bag designed to replace ‘outdated and unsafe’ portable medical bags could transform treatment around the world, says its manufacturer. A study found a third of its outdated predecessors carry the MRSA bug. In 2008, East Riding of Yorkshire (NHS ERY) introduced the first of its Neighbourhood Care Teams (NCT) to enable patients with long-term illnesses to receive treatment at home. NCTs now provide over 450,000 patient contacts each year.
Silicone and living cardiac muscle cells have been combined to form a freely swimming "jellyfish", proof of concept for reverse engineering a variety of muscular organs and simple life forms.
It also suggests a broader definition of what counts as synthetic life.
Study co-author Kevin Kit Parker previously demonstrated bioengineered constructs that can grip, pump, and even walk. He says the inspiration to mimic a jellyfish came out of frustration with the state of the cardiac field. Similar to the way a human heart moves blood throughout the body, jellyfish propel themselves through the water by pumping. In figuring out how to take apart and then rebuild the primary motor function of a jellyfish, the goal was to figure out how such pumps really worked.
