Input: Consider 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."

Output: Long-lived bats offer clues on diseases, aging.

Input: Consider Input: President Alberto Fernandez earlier this week ordered all but essential workers to stay home and off the streets. But he was forced to amend the list of exceptions after receiving a message from the mother of a 7-year old boy who had recently lost his first tooth. "Dear @alferdez, I need to ask if the tooth fairy is among those exempted from quarantine? Joaquin has lost his first tooth and we don't know if we should leave him a letter (we can't find the tooth). We don't want to cause the tooth fairy problems or for the police to detain him." Fernandez reassured the boy an hour later that the tooth fairy was indeed on the official list of exceptions. "@littlekbz Cecilita! The tooth fairy can leave rewards for fallen teeth because he is not under quarantine. But the rest of us are... Joaquin should leave the tooth beneath his pillow and enjoy the prize," Fernandez wrote on Twitter. Aside from the tooth fairy, Argentina has also exempted key agricultural and export industry workers from the lockdown, and allows people on the streets to buy groceries and medicine, and for urgent medical needs. The country thus far has confirmed 158 cases of coronavirus and four deaths from the disease. Click here for a GRAPHIC on Argentina coronavirus cases

Input: Consider Input: U.N. officials and donors met in Geneva to discuss how to tackle the world's second worst epidemic, which has infected 2,500 people and killed 1,655 in the lush farmlands of eastern Democratic Republic of Congo. A toxic mix of armed militias and a deep-rooted mistrust of health officials by communities have hampered efforts to halt the virus. Goma, a lakeside city more than 350 kilometres (220 miles) south of where the outbreak was first detected, got its first case on Sunday. That raised fears Ebola could accelerate into one of Africa's most densely populated areas and over the Rwanda border. "The case in Goma could potentially be a gamechanger in this epidemic," WHO Director-General Tedros Adhanom Ghebreyesus told the meeting. "It is a gateway to the region and the world." The patient who brought Ebola to Goma was a priest who became infected during a visit to the town of Butembo, 200 km (124 miles) north of Goma, where he interacted with Ebola patients, Congo's health ministry said in a statement. He was taken back to a clinic in Butembo on Monday. "Due to the speed with which the patient has been identified and isolated, as well as the identification of all bus passengers from Butembo, the risk of spreading to the rest of the city of Goma remains low," the ministry said. WHO emergencies chief Mike Ryan said they had identified 60 contacts, including 18 who were on the bus with the priest, and half of them have been vaccinated. Goma had been preparing for the arrival of Ebola for a year, setting up hand-washing stations and making sure moto-taxi drivers do not share helmets. "There is a grave risk of a major increase in numbers, or spread to new locations as we've heard today in Goma," said Josie Golding, a specialist on epidemics at the Wellcome Trust global health charity. Ebola causes diarrhoea, vomiting and hemorrhagic fever and can be spread through bodily fluids. An epidemic between 2013 and 2016 killed more than 11,300 people in West Africa. While the technology for fighting it, including vaccines and special treatment units, is better than ever, trust between health workers and the community is low and militia violence is preventing them from accessing remote areas. Unidentified attackers killed two Ebola health workers near Mukulia in North Kivu province over the weekend, the latest in a string of assaults this year that have injured or killed dozens of responders. "Every attack gives Ebola an opportunity to spread. Ebola gets a free ride," Ghebreyesus said. Apart from insecurity, the biggest challenge is money, officials said. "If we don't raise more resources ... it is not going to be possible to bring this outbreak under control," the U.N.'s humanitarian chief Mark Lowcock told Reuters. "The need is for money, not next week, or next month or later in the year. The need is for money now."
