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: "In a Dec. 15, 2015, interview with actress and writer Lena Dunham in Lenny Letter, Dunham’s feminist email newsletter, Planned Parenthood President Cecile Richards discussed testifying to Congress, running Planned Parenthood in the wake of the shooting in Colorado Springs and her experiences fighting for reproductive rights. Their conversation came as Republicans in Congress continued to seek an end to any federal aid to Planned Parenthood in the same year videos released by an anti-abortion group purported to show Planned Parenthood officials discussing the use of fetal tissue in medical research. Federal funding to Planned Parenthood does not go toward abortions and is instead used to fund the organization’s other services, such as sexually transmitted disease testing and treatment, mammograms and contraceptive services. In the interview, Dunham asked Richards about changes in the politics of abortion rights over Richards’ nine years as president of Planned Parenthood. Richards, eldest daughter to Ann Richards, the late former Texas governor, replied by mentioning the partisan realignment of legislatures in 2010, which mostly benefited Republicans, and the Republican Party’s national shift to the right. ""But if you look at the people in this country,"" Richards continued, ""they are supportive of safe and legal abortion. They support Planned Parenthood. I was just looking at the recent numbers. More than 60 percent of people in America support Planned Parenthood, and only 11 percent approve of Congress."" Those numbers, Richards said, show that ""just because the politics are going one way, it’s not because that’s where the people are."" Where the people are is a pretty broad assessment. We focused on whether Richards was right about the relative popularity of Planned Parenthood and unpopularity of Congress. Congressional approval Congress hasn’t been widely admired very often. As we noted in a December 2014 story, the Gallup polling organization started inquiring into attitudes toward Congress in 1974. Its results show Congress never proving very popular, except after the 9/11 attacks, when there was a spike to 84 percent of respondents approving of the job Congress was doing. The most recent Gallup poll available at the time of Richards’ interview placed public approval of Congress at 11 percent. (After that, according to Gallup, support edged up to 13 percent.) The poll, conducted from Nov. 4 to Nov. 8, 2015, asked respondents, ""Do you approve or disapprove of the way Congress is handling its job?"" A whopping 86 percent disapproved, and 3 percent had no opinion. Eleven percent approval was a low point for Congress in 2015. Twenty percent approved of Congress in February 2015, and 19 percent approved in May 2015. Approval of Congress declined starting in May 2015, reaching 14 percent in August 2015 and 13 percent in October 2015, before hitting 11 percent the next month. A poll released Dec. 3, 1015, by Rasmussen Reports placed public support for Congress even lower: 9 percent of likely voters said Congress was doing a good or excellent job according to Rasmussen’s methodology, which in 2015 often returned lower favorability numbers than Gallup’s polls. Support for Planned Parenthood funding In reviewing the other end of Richards’ claim, we recognized two ways to gauge ""support"" for Planned Parenthood. Polls in 2015 inquired into U.S. attitudes about ending federal aid to the group and about general feelings about the group which, we’ve noted, provides family planning and other women’s health services, including abortions. Planned Parenthood, asked for the factual backup to Richards’ statement, pointed us to several surveys showing support for the group itself and support for its funding as well as opposition to shutting down the government rather than continuing its aid. An Oct. 14, 2015, PolitiFact Wisconsin fact-check found True this September 2015 claim by Wisconsin Democrat Gwen Moore: ""60 percent of all Americans do not want to see Planned Parenthood defunded."" Three September 2015 surveys--similarly cited by Planned Parenthood when we made our recent inquiry--seemed to back Moore’s claim: • A NBC News/Wall Street Journal poll of adults asked: ""Would you favor or oppose totally eliminating federal funding to Planned Parenthood for family planning and preventative health services?"" Sixty-one percent of respondents opposed eliminating federal funding to Planned Parenthood. • A USA Today/Suffolk University poll of likely voters asked: ""Do you think all federal funding for Planned Parenthood should be cut off: yes or no?"" Sixty-five percent said no. A similar poll conducted in December 2015 saw that number down slightly at 58 percent. • A Pew Research Center poll tied Planned Parenthood funding to a possible government shutdown in its question but got a similar result: 60 percent of adults said any federal budget agreement to avert a government shutdown would have to maintain funding for Planned Parenthood. Another survey, however, did find support for eliminating Planned Parenthood’s funding. Released Dec. 2, 2015, the poll from the Robert Morris University Polling Institute found that 53.3 percent of respondents supported defunding Planned Parenthood, and 31.5 percent opposed it. The RMU polling institute speculated in its news release that the starkly different response stemmed from the wording used in the polling question. The RMU poll asked respondents: ""Congressional Republicans favor shifting Planned Parenthood federal funds to community clinics that perform the same services, but do not perform abortions. Would you say you support or oppose this plan?"" Other polls generally asked a version of the question, ""Do you think all federal funding to Planned Parenthood should be cut off?"" without mentioning clinics, services, or abortions. The RMU poll stood alone in finding support for defunding Planned Parenthood. Support for Planned Parenthood Survey questions asking directly about support for Planned Parenthood in itself — rather than its government backing — had positive responses, at lower numbers than the 60 percent mark. These polls all asked a version of the simple question, ""Is your opinion of Planned Parenthood favorable or unfavorable?"" An Oct. 6, 2015, poll by Rasmussen Reports, which Planned Parenthood also shared with us, found that 53 percent of likely voters had a favorable opinion of Planned Parenthood, with a margin of error of 3 percent. A Bloomberg National Poll in November 2015 got 50 percent favorability for the organization, with the same margin of error. A Sept. 28, 2015, poll from Quinnipiac University delivered lower numbers: it found that 44 percent of Americans had a favorable opinion of Planned Parenthood, compared with 39 percent unfavorable, with a 2.5 percent margin of error. The lowest favorability ratings came from a September 2015 CBS News/New York Times poll, which found 40 percent in favor and 27 percent not in favor. Thirty-one percent in that poll said they did not know enough to answer the question. By email, Planned Parenthood media relations assistant Claire Barnes pointed to an Aug. 5, 2015, NBC News/Wall Street Journal poll that put Planned Parenthood’s favorability ratings in context. The poll found Planned Parenthood’s 45 percent favorability rating was higher than favorability ratings for the NRA, the Supreme Court, Bernie Sanders, President Barack Obama and several Republican presidential candidates included in the survey. Our ruling Richards said that more than 60 percent of people in America support Planned Parenthood, and only 11 percent approve of Congress. Richards had a bead on Congress, which was wallowing in 11-percent approval territory in November 2015. In addition, most polls suggested more than 60 percent of Americans opposed the federal defunding of Planned Parenthood. Still, there’s clarification missing. While more people look favorably on Planned Parenthood than not, polls indicated, that was the opinion of 40 percent to 53 percent of Americans--not more than 60 percent. The statement is accurate but needs clarification or additional information."
Example Output: More than 60 percent of people in America support Planned Parenthood and only 11 percent approve of Congress.

Example Input: Seasoned explorer Robert Swan and his 23-year-old son Barney will begin their eight week, 600-mile expedition on Wednesday, hoping to show renewable energy can work in extreme conditions and prove a viable alternative to fossil fuels. “For the first time in history we will be surviving only on renewable energy. It’s never been done,” 61-year-old polar veteran Swan, the first person to walk to both the North and South poles, told Reuters. The Swans’ 5,000 daily calorie intake will come from sustainable and energy-giving foods, such as grains and almond bars, to help them overcome temperatures of -40 degrees Celsius and the obvious risks of frostbite, altitude sickness and snow blindness. Perpetual sunlight will charge the solar panels, which will power a NASA-designed ice melter to provide them with enough water for drinking and cooking. “Water is gold down in Antarctica, without it you’re going to be dying pretty quickly, as dad always reminds me,” said Barney Swan. While their aim is to complete the trek using just solar energy, under extreme weather conditions they’ll turn to an advanced biofuel made out of wood chip waste. “The fuels have been tested to minus 60 degrees Celsius...it won’t get as cold as minus 60. We may get minus 40 which is, trust me, cold enough,” the elder Swan said.
Example Output:
Father-son team plans Antarctic trek powered by renewable energy.
