Example Input: Siteman Cancer Center at Barnes-Jewish Hospital plans to open a second proton therapy center in 2020, and Mercy Hospital St. Louis expects to open its own proton center two years later, The St. Louis Post-Dispatch reported . Proton therapy zap cancerous cells with precise beams of radiation while sparing surrounding tissue. Unlike traditional X-rays, the proton beams stop at the tumor instead of traveling through the body. The new $32 million proton system planned at Barnes-Jewish Hospital will provide "pencil-beam" precision to target tumors, said Dr. Jeffrey Bradley, director of Siteman's S. Lee Kling Proton Therapy Center. It will be built next to a $20 million machine, which opened in late 2013, that uses magnets to scatter proton beams across a tumor. Siteman has treated about 800 patients with the proton therapy, close to its projections of 200 patients a year. The first proton centers built in the 1990s were known for their football-field size and up to $200 million price tag. To offset the costs, the centers marketed heavily to men with prostate cancer, despite a lack of evidence that patients have better outcomes or fewer side effects compared to cheaper treatment alternatives. In 2013, Washington University was the first to open a smaller, less-expensive proton system with one treatment room. "That's very different from other centers that went all in, borrowed money, and put in four-room centers," Bradley said. "The one room at a time idea is a very viable idea." Bradley and other radiation oncologists say a major hurdle is insurance companies' reluctance to cover proton therapy. That can cost 50 percent to 75 percent more than traditional radiation, according to industry groups. "Where the insurers like to say that proton therapy is not beneficial is often because they do not perform an adequate review of the evidence," said Scott Warwick, executive director of the National Association for Proton Therapy. "We have notified the payers that they have often either misinterpreted data, reviewed older evidence or omitted key evidence in development of their coverage policies." ___ Information from: St. Louis Post-Dispatch, http://www.stltoday.com
Example Output: St. Louis medical organizations plan more proton therapy.

Example Input: Studying the DNA of two distant bat species, the scientists discovered how genes dealing with the bats' immune system had undergone the most rapid change. This may explain why they are relatively free of disease and live exceptionally long lives compared with other mammals of similar size, such as the rat, said Professor Lin-Fa Wang, an infectious disease expert at the Duke-NUS Graduate Medical School in Singapore who led the multi-centre study. "We are not saying bats never get sick or never get infections. What we are saying is they handle infections a lot better," Wang said in a telephone interview. What was missing from both species of bats was a gene segment known to trigger extreme, and potentially fatal, immune reactions to infections, called the cytokine storm. Cytokine storms end up killing not only offending viruses in the body, but the host's own cells and tissues too. "Viruses rarely kill the host. The killing comes from the host's immune response. So it looks like what bats are doing is depress the inflammation (cytokine storm). If we can learn that, we can design drugs to minimize the inflammation damage and control viral infection," Wang said. The study, which saw the participation of researchers from China, Denmark, Australia and the United States, was published on Friday in the journal Science. Compared with other mammals of similar size, bats live a long time, with lifespans of between 20 and 40 years. Rats live between 2 and 3 years, on average. Interestingly, Wang and his colleagues found that the highly evolved genes that give bats their superior immune system also enable them to fly. Out of more than 5,000 types of mammals on the planet, bats are the only one capable of sustained flight and some species can fly more than 1,000 km in a single night. Such intense physical exertion is known to produce toxic "free radicals" that cause tissue damage and it is these same genes that give the bat the ability to repair itself, Wang said. "What we found was the genes that evolved fastest were genes involved in repairing DNA damage. That makes sense ... because when you fly, metabolism goes up and it generates free radicals that are toxic to cells," Wang said. "Because bats fly, they (would have had) to evolve and adapt ... to get genes that can repair DNA damage." Wang said we have much to learn from the bat, which has evolved to avoid disease and live exceptionally long lives. "Cancer, ageing and infectious disease, these are the three major areas of concern for people," he said. "We have studied rats for 150 years to understand how to do better in these three areas. Now we have a system, the bat, that has done very well in evolution. We can learn from the bat. With modern techniques, we can design new drugs to slow down the ageing process, treat cancer, fight infections."
Example Output: Long-lived bats offer clues on diseases, aging.

Example Input: Stewart, who visited the Ebola zone earlier this month, told a U.N. meeting that Britain had donated $45 million towards a previous Ebola outbreak and the current one, and that he had authorized a further $63 million of British spending. "We are going to have to put a lot more money into this on a 'no regrets' basis," he told the meeting, adding that governments must stop using security concerns as an excuse not to send staff to the Ebola front line, where armed groups have frequently attacked aid workers. The United States, Britain and Germany had all donated generously, but other members of the G7 group of countries needed to do more, Stewart said. "We would be hugely grateful if our dear friends from the other G7 countries really stepped up," he added. Money was the priority, but French language expertise was also valuable, and francophone France and Canada could make a special contribution. "It would be wonderful if some francophone countries could provide more staff on the ground. We desperately need more French speakers deployed in the field," he said. Stewart told BBC radio that he would be asking the French and Canadian governments to make more generous contributions. The World Health Organization's emergencies chief, Mike Ryan, said Canada had contributed $750,000 directly to the WHO effort, but had also donated to other agencies. It was also Canadian government money that funded the development of the Ebola vaccine that has saved many lives. "With regard to the government of France, we rely on the government of France for a lot of technical cooperation, but as of this moment WHO has not received any financial contributions from the government of France," Ryan said. Stewart said some donors at the packed U.N. meeting believed the response was well funded. "The World Bank has been making very positive comments about how they've got it all under control. They haven't," he said, adding that money was needed to double the number of WHO staff helping Congo's neighbors, such as Burundi and South Sudan, prepare for a potential outbreak.
Example Output:
Britain tells Canada and France to pull their weight on Ebola.
