[Q]: 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.”

[Q]: In its latest Strategy Update, the U.N. agency said that the world stands at a “pivotal juncture” in the pandemic and that “speed, scale, and equity must be our guiding principles” when deciding what measures are necessary. Every country should implement comprehensive public health measures to maintain a sustainable steady state of low-level or no transmission and prepare its surge capacity  to react rapidly to control any spread, the WHO said. Some of the countries hardest-hit by the virus are now considering lifting lockdowns and beginning the transition toward a resumption of normal life. The WHO update said any such  steps should be taken gradually, with time to evaluate their impact before new steps are taken. “To reduce the risk of new outbreaks, measures should be lifted in a phased, step-wise manner based on an assessment of the epidemiological risks and socioeconomic benefits  of lifting restrictions on different workplaces, educational institutions, and social activities...,” the WHO said. “Ideally there would be a minimum of 2 weeks (corresponding to the incubation period of COVID-19) between each phase of the transition, to allow sufficient time to understand the  risk of new outbreaks and to respond appropriately,” it added. It warned that the “risk of re-introduction and resurgence of the disease will continue”. The Geneva-based global health organisation issued its advice at a time when it has come under criticism from the United States for its initial response to the pandemic. President Donald Trump said on Tuesday Washington, the WHO’s biggest donor, would suspend funding. China has begun lifting some of the toughest restrictions imposed on Hubei province where the disease first emerged at the end of last year. In the United States, which has the largest number of confirmed cases and deaths, Trump has jostled with some state governors over who has the authority to begin reopening U.S. businesses. European countries have begun small-scale steps to reduce severe lockdowns. Some Spanish businesses, including construction and manufacturing, have been allowed to resume, although shops, bars and public spaces are to stay closed until at least April 26. Italy, which has the world’s second-highest death toll at 21,067, maintained some tight restrictions on movement, while Denmark, one of the first European countries to shut down, will reopen daycare centres and schools for children in first to fifth grades on Wednesday.

[Q]: Example:   [Collected via e-mail, May 2011] I don’t know who wrote the article, but have a friend who is a pro golfer. He confirmed that Ping indeed does do this. What a great gesture… and they don’t even use it as a promo gimmick. Now that’s class. This isn’t a joke or cartoon; just something interesting to know… you may want to forward this on to others.On Monday, I played the Disney, Lake Buena Vista course. As usual the starters matched me with three other players. After a few holes we began to get to know each other a bit. One fellow was rather young and had his wife riding along in the golf cart with him. I noticed that his golf bag had his name on it and after closer inspection, it also said “wounded war veterans”. When I had my first chance to chat with him I asked him about the bag. His response was simply that it was a gift. I then asked if he was wounded and he said yes. When I asked more about his injury, his response was “I’d rather not talk about it, sir”. Over a few holes I learned that he had spent the last 15 months in an army rehabilitation hospital in San Antonio Texas . His wife moved there to be with him and he was released from the hospital in September. He was a rather quiet fellow; however, he did say that he wanted to get good at golf. We had a nice round and as we became a bit more familiar I asked him about the a brand new set of Ping woods and irons he was playing. Some looked like they had never been hit. His response was simple. He said that this round was the first full round he had played with these clubs. Later in the round he told me the following. As part of the discharge process from the rehabilitation hospital, Ping comes in and provides three days of golf instruction, followed by club fitting. Upon discharge from the hospital, Ping gives each of the discharged veterans, generally about 40 soldiers, a brand new set of custom fitted clubs along with the impressive golf bags. The fellow I met was named Ben Woods and he looked me in the eye and said that being fitted for those clubs was one of the best things that ever happened to him and he was determined to learn to play golf well enough to deserve the gift Ping had given him. Ben is now out of the service, medically discharged just a month ago. He is as fine a young man as you would ever want to meet. Ping has the good judgment not to advertise this program. God Bless America and the game of golf. The item quoted above refers to PING’s being one of the Gold Sponsors of Disabled Sports USA’s (DS/USA) Wounded Warrior Disabled Sports Project (WWDSP): Through this program, service men and women severely wounded in the wars in Iraq and Afghanistan, will participate in a summer-long sports rehabilitation program offered by Disabled Sports USA (DS/USA) in partnership with the Wounded Warrior Project and 29 DS/USA chapters across the country. The program includes a series of more than 60 “learn-to” clinics in cycling, golf, sailing, outrigger canoeing, kayaking, scuba, rock climbing, camping, water skiing, rafting, wake boarding, track and field, fishing, equestrian, ropes courses and other sports.The WWDSP also provides advanced level training and competitions to help wounded warriors remain active throughout their lives with some participants going on to compete at the Paralympic level or becoming active mentors in DS/USA chapter activities when they return to civilian life. The Wounded Warrior Project leads funding of the WWDSP which enables Disabled Sports USA to provide all programs free of cost for severely wounded service members and their families. This includes the cost of transportation, special adaptive sports equipment, training from qualified adaptive sports instructors, lodging, meals and other expenses. In addition, Gold Sponsors include: Ariel Corporation; Bank of America; The Chart Group; Trijicon; Non Commissioned Officers Association; Tee It Up For The Troops; Robert Trent Jones Golf Club Charitable Foundation; PING; US Association of Former Members of Congress; The Darby Foundation. Silver Sponsors include: Battelle; HUB Financial Charities; Fournier Family Foundation; Moore Capital Management; Miami International Holdings; Phoenix Beverages; PGA of America. In response to our inquiry, PING told us that: PING is proud to be involved with the Wounded Warriors Sports Project. The Project is currently partnering with PGA of America to offer golf lessons at five of the major military medical centers in the U.S. The format involves running an eight week long course where Warriors receive instruction from PGA professionals that have been trained in adaptive teaching techniques. Those wounded warriors who attend at least six of the training sessions and have a permanent severe disability receive a full bag of custom-fit and custom-built PING golf clubs.
