[Q]: Mustapha Redouane happily accepted the arrangement. He knew his mother's idea would silence the school's worries about his condition, a rare genetic disorder called xeroderma pigmentosum, or XP, which can make sun rays and other sources of ultraviolet light extremely damaging to the skin and eyes. The disorder is more common in North Africa than much of the world. "I hate the sun anyways. It gives me blisters," he said, sitting on his mother's lap, his face covered with the dark brown freckles that the school director considered a distraction to other students. Now 8, Mustapha has already had 11 operations to remove cancerous growths on his skin. His family is among thousands around the world struggling with XP, and increasingly sharing advice and seeking new treatments. In Morocco, families are also fighting for recognition, government help and the simple right to go to school. The disorder affects about 1 in 10,000 people in North Africa more than 10 times the rate in Europe and about 100 times the rate in the United States, according to Dr. Kenneth Kraemer, who researches XP at the U.S. National Institutes of Health. Because the disorder is inherited, XP is more common in populations where marriage between relatives is high, Kraemer said. Affected children inherit two copies of a mutated gene, one from each parent. A 2016 Moroccan government study estimates about 15% of marriages are between family members. Living in a country where the sun shines year-round makes them more susceptible to skin cancers that can be caused by the disorder, said Fatima El Fatouikai, pediatric dermatology specialist at the Ibn Rochd University Hospital in Casablanca. Without protection, few XP patients in Morocco live beyond their teenage years, El Fatouikai said. It is particularly challenging in developing countries, where an awareness of the disorder and access to treatments are scarce, and in poor, rural communities where people spend more time outside. Outside of El Fatoikai's office, families coming from all around Morocco sit in a waiting room eager for their names to be called. There is a rumor about a new XP treatment. The truth is, she says, "We only have prevention as a possible treatment. These children ... have to avoid even minimum sun exposure." The main prevention measures: avoiding the sun and wearing protective clothing, face shields and sunscreen. Fatimazehra Belloucy, 25, has dealt with skin cancer and other problems because of XP. "If only people made it easier. Their words hurt. I feel entirely alienated," she said, describing how she faces scared looks and hateful comments as she passes by. Her family limits interactions with her, fearful that the disease is contagious. "No one would take care of me, so I had to do it myself," said Belloucy, who received her high school diploma and is now enrolled in university. She hopes to land work helping with the disease. Most Moroccan children with XP don't continue their education. While U.S. schools install window filters for XP pupils and otherwise adapt to their needs, such accommodations are rare in Morocco. "It hurts me that I have to see little kids suffer because of lack of awareness," says Habib El Ghazaoui, who quit his veterinary job and made it his life's mission to raise awareness and help children with XP after learning that his daughter Fatimazehra had the disorder. His daughter, now a young adult raising awareness on social media, has had 50 operations for cancerous growths on her tongue, eyelids and elsewhere. She stays indoors and mostly sleeps during the day but, as the sun sets, she goes to parks and cafes, determined to lead a normal life. Ghazaoui leads the Association for Solidarity with Children of the Moon from his house in the town of Mohammedia. He juggles his time between visiting families, distributing donations of creams and masks, providing the Casablanca hospital with data and pressuring the government to take action. XP support groups are increasingly sharing advice online. They held an exceptional meeting in London last year to share "hundreds of practical hints" about hoods, window protections or meters to measure light and even a French-designed face shield with a fan in it, said NIH researcher Deborah Tamura. The donations from Ghazaoui's group reach families like those of Said El Mohamadi, a tailor in the city of Sale, whose 6-year-old daughter has the condition. His family is still debating the topic of school. "She's sad, but I can't risk taking her to school where there isn't any kind of protection," he said. "But she needs an education," her mother Maria El Maroufi pleads. ___ Nadine Achoui-Lesage and Mosa'ab Elshamy in Casablanca and Mohammedia contributed.

[Q]: Scientists said on Wednesday many Tibetans possess a rare variant of a gene involved in carrying oxygen in the blood that they likely inherited from an enigmatic group of extinct humans who interbred with our species tens of thousands of years ago. It enables Tibetans to function well in low oxygen levels at elevations upwards of 15,000 feet (4,500 meters) like the vast high plateau of southwestern China. People without this variant would be apt to develop thick blood, leading to high blood pressure, heart attacks, strokes, low-birth-weight babies and higher infant mortality. This version of the EPAS1 gene is nearly identical to one found in Denisovans, a lineage related to Neanderthals - but is very different from other people today. Denisovans are known from a single finger bone and two teeth found in a Siberian cave. DNA testing on the 41,000-year-old bone indicated Denisovans were distinct from our species and Neanderthals. "Our finding may suggest that the exchange of genes through mating with extinct species may be more important in human evolution than previously thought," said Rasmus Nielsen, a computational biology professor at the University of California, Berkeley and the University of Copenhagen, whose study appears in the journal Nature. Our genome contains residual genetic fragments from other organisms like viruses as well as species like Neanderthals with which early modern humans interbred. The researchers called their study the first to show that a gene from an archaic human species has helped modern humans adjust to different living conditions. "Such exchange of genes with other species may in fact have helped humans adapt to new environments encountered as they spread out of Africa and into the rest of the world," said Nielsen. Asan Ciren, a researcher with China's BGI genomics center, added, "The genetic relationship or blood relationship between modern humans and archaic hominins is a hot topic of the current paleoanthropology." The researchers said early modern humans trekking out of Africa interbred with Denisovans in Eurasia en route to China. Their descendants harbor a tiny percentage of Denisovan DNA. Genetic studies show nearly 90 percent of Tibetans have the high-altitude gene variant, along with a small percentage of Han Chinese, who share a common ancestor with Tibetans. It is seen in no other people. The researchers conducted genetic studies on 40 Tibetans and 40 Han Chinese and performed a statistical analysis showing that the gene variant almost certainly was inherited from the Denisovans. The gene regulates production of hemoglobin, a protein in red blood cells that carries oxygen. It is turned on when blood oxygen levels drop, stimulating more hemoglobin production. At elevations above 13,000 feet (4,000 meters), the common form of the gene boosts hemoglobin and red blood cell production, causing dangerous side effects. The Tibetans' variant increases hemoglobin and red blood cell levels only modestly, sparing them these effects.

[Q]: About 2 years ago my wife and I were on a cruise through the western Mediterranean aboard a Princess liner. At dinner we noticed an elderly lady sitting alone along the rail of the grand stairway in the main dining room. I also noticed that all the staff, ships officers, waiters, busboys, etc., all seemed very familiar with this lady. I asked our waiter who the lady was, expecting to be told she owned the line, but he said he only knew that she had been on board for the last four cruises, back to back. As we left the dining room one evening I caught her eye and stopped to say hello. We chatted and I said, "I understand you've been on this ship for the last four cruises." She replied, "Yes, that's true." I stated, "I don't understand" and she replied, without a pause, "It's cheaper than a nursing home." So, there will be no nursing home in my future. When I get old and feeble, I am going to get on a Princess Cruise Ship. The average cost for a nursing home is $200 per day. I have checked on reservations at Princess and I can get a long term discount and senior discount price of $135 per day. That leaves $65 a day for: 1. Gratuities which will only be $10 per day. 2. I will have as many as 10 meals a day (of fantastic food, not institutional food) if I can waddle to the restaurant, or I can have room service (which means I can have breakfast in bed every day of the week). 3. Princess has as many as three swimming pools, a workout room, free washers and dryers, and shows every night. 4. They have free toothpaste and razors, and free soap and shampoo. 5. They will even treat you like a customer, not a patient. An extra $5 worth of tips will have the entire staff scrambling to help you. 6. I will get to meet new people every 7 or 14 days! 7. TV broken? Light bulb need changing? Need to have the mattress replaced? No problem! They will fix everything and apologize for your inconvenience. 8. Clean sheets and towels every day, and you don't even have to ask for them. 9. If you fall in the nursing home and break a hip you are on Medicare; if you fall and break a hip on the Princess ship they will upgrade you to a suite for the rest of your life. 10. There is always a doctor on board. Now hold on for the best! Do you want to see South America, the Panama Canal, Tahiti, Australia, New Zealand, Asia, or name where you want to go? Princess will have a ship ready to go. So don't look for me in a nursing home, just call shore to ship. PS: And don't forget, when you die, they just dump you over the side at no charge. Origins: Although the "cruise ship" recounting has become the more widespread, the earlier form taken by this piece of e-lore featured not a luxury liner but a hotel. In 2003 this waggish diatribe against the cost of nursing home care had its writer swearing to check into a Holiday Inn when the grey hairs became too many. By 2004, some of the numbered items now found in the "cruise ship" tale were in place, albeit in a version that claimed Holiday Inn rather than Princess as substitute elder care housing (e.g., "TV broken? Light bulb need changing? Need to have the mattress replaced? No problem! They will fix everything and apologize for your inconvenience"). By 2005 more numbered items had been added, including some cruise-specific ones (e.g., "There is always a doctor on board" and "And don't forget, when you die, they just dump you over the side at no charge"). Also by 2005, what had begun as one writer's claim about his or her fanciful future plans had come to be presented as the actual remarks of an old woman living that life on a cruise ship. It is at this intersection that folklore and reality: while the account of the "elderly lady" has clearly evolved from earlier pieces about pie-in-the-sky retirement plans involving Holiday Inn, some people of advanced years have indeed made their homes on cruise ships. Bea Muller, an 86-year-old retiree, took up residence on Cunard's Queen Elizabeth 2 on 5 January 2000. Her husband had passed away while the couple was on a world cruise eleven months earlier, and rather than opt for a retirement home, Mrs. Muller sold her house and possessions and booked herself onto the ship. Instead of submitting a monthly or yearly fee, in 2001 Muller was reported to be paying as she went, booking one cruise after another. Thanks to her frequent traveler discounts, her overall costs amounted to about $5,000 a month. (Cruise prices have increased since then, which is something those entertaining similar plans should keep in mind. Also, Muller's accommodations were small and windowless: a 1010 foot cabin that barely fits a bed, radio, and television, with a bathroom smaller than the average closet found in a typical home.) Its cramped quarters aside, Muller was happy with her life aboard a ship. "I've got full-time maid service, great dining rooms, doctors, medical center (where she volunteers), a spa, beauty salon, computer center, entertainment, cultural activities and, best of all, dancing and bridge." (Muller passed away in 2013, and the Queen Elizabeth 2 was retired from service in 2008.) Bea Muller was not the first long-time cruiser: Cunard had a previous guest, Clair MacBeth, who lived aboard ship for 14 years. As to whether living out one's golden years aboard a cruise ship is a viable alternative to spending them in a retirement home, a geriatrician at Northwestern University says such a plan is a feasible and cost-effective alternative to assisted-living facilities. Dr. Lee Lindquist, an instructor at Northwestern's Feinberg School of Medicine, compared the costs (over a 20-year life expectancy) of moving to an assisted-living facility, a nursing home and a cruise ship, including the expense of treating acute illnesses, Medicare reimbursement and other factors. She determined that the net cost of cruise-ship living was only about $2,000 more than the alternatives ($230,000 versus $228,000) and offered a higher quality of service. "Cruise ships offer such a range of amenities such as three meals a day, often with escorts to meals if needed, room service, entertainment, accessible halls and cabins, housekeeping and laundry services and physicians on board that they could actually be considered a floating assisted-living facility," says Lindquist. Lindquist says the plan would work best for seniors who need a minimal amount of care. "Seniors who enjoy travel, have good or excellent cognitive function but require some assistance with activities of daily living are the ideal candidates for cruise-ship care. Just as with assisted living, if residents became acutely ill or got to the point that they needed a higher level of care, they would have to leave." Although Lindquist's findings would seem to support the premise of it being cheaper to live on a luxury liner than in a retirement home, we'd want to examine her research vis-a-vis the types of care facilities she looked at and the cruise-ship costs she factored in before we'd feel comfortable about offering an opinion on her assessment. (She might have compared only very expensive retirement homes against the cheapest accommodations offered on ships that are less than well thought of, for example.) However, whatever the validity of Lindquist's findings, cost is but one of the elements to the choice of where to reside after retirement. Golden agers who decide to make their permanent homes on cruise ships sacrifice proximity to family and friends; their nearest and dearest are no longer just a short car ride away. Those devoted to their children and grandchildren might well deem that too high a price to pay, no matter what the spreadsheet says about the relative financial costs. Likewise, those who lack progeny but who are involved in their communities or who are part of a number of strong friendships may not want to opt for the vagabond life, because it would mean abandoning that which gives them joy.
