What Is Radiotherapy? What Is Radiation Therapy?
Radiotherapy is also known as radiation therapy, radiation oncology and XRT. It is used for treating cancer, thyroid disorders and some blood disorders. Approximately 40% of cancer patients undergo some kind of radiotherapy. It involves the use of beams of high-energy X-rays or particles (radiation) to destroy cancer cells. Radiotherapy works by damaging the DNA inside the tumor cells, destroying their ability to reproduce.

Close Relationship Between Past Warming And Sea-Level Rise
In a paper in Nature Geoscience, a team from the National Oceanography Centre, Southampton (NOCS), along with colleagues from TÃøbingen (Germany) and Bristol presents a novel continuous reconstruction of sea level fluctuations over the last 520 thousand years. Comparison of this record with data on global climate and carbon dioxide (CO2) levels from Antarctic ice cores suggests that even stabilisation at today"s CO2 levels may commit us to sea-level rise over the next couple of millennia, to a level much higher than long-term projections from the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).

Only Drop-In Needle Exchange Center In Minnesota Closes Due To Lack Of Funding

Minnesota"s only storefront needle exchange drop-in center, called Access Works!, "fell victim to economic hard times and federal anti-drug policies" and ended its program last week after 13 years, the Minnesota Independent reports. The program "traded used needles for clean ones, conducted HIV and Hepatitis C testing, taught overdose prevention, held support groups and connected users with chemical dependency treatment experts," according to the Independent. Federal funding cannot be used to administer needles for such programs, Lauri Wollner, executive director of the program said. She added, "The federal ban has had a long-term impact. We spend almost $40,000 a year on needles and about $5,000 a year on disposal (of used needles)." Private donations also have been down, she said. While the ban on the use of federal funding for needle exchange is being revisited by Congress, "local needle-exchange activists say it is doubtful that congressional action will be able to save the struggling organization," the article states (Birkey, 8/3).
