Nashville, Tennessee, is known for serving up entertainment and alcohol.“You’re thinking you’re coming here to see mountains, no,” said Reggie Small, general manager of Tailgate Brewery Music Row. “In Nashville, you’re eating and drinking and having a good time."Bartenders like Small are having a tough time making tips like they used to.“You’re used to that everyday paycheck, everyday money from your day shift to the end of the night,” he said. “But without having that, your savings are going to run out sooner or later.”When the COVID-19 crisis first hit, Small had to cut his staff to managers only. Fewer customers bellying up to the bar meant sales started to slip, not only in Nashville, but across the country.“It’s devastating everywhere,” said Aaron Gregory Smith of the United States Bartenders’ Guild. “And the hardest thing is just not knowing what is going to happen next week or next month.”Smith and his team recently started the Bartender Emergency Assistance Program COVID-19 Relief Campaign, giving away nearly .5 million to more than 32,00 bartenders across America.“We feel pretty good about getting money into hands of people who pretty much overnight lost their jobs, lost their income,” Smith said.The money comes from a combination of alcohol suppliers and individual donors. To get the money, bartenders needed to fill out an application and they’re selected based on need.That money, however, recently ran out. The US Bartenders’ Guild is now looking for more fundraising and government assistance.“It’s hard to watch a community, an industry that I’ve been part of going on 25 years now, going through the really most catastrophic shift that we’ve been through since prohibition,” Smith said.For bartenders like Small, he’s adjusting to keep his staff making money as the winter months move in and outdoor dining becomes less of an option.“Not having job security is really, really stressful on people,” he said. “I’ve seen it been a struggle for a lot of people in the profession just because of the everyday unknown.” 2060

Millions of women and girls globally have lost access to contraceptives and abortion services because of the coronavirus pandemic. Now the first widespread measure of the toll says India with its abrupt, months-long lockdown has been hit especially hard.Several months into the pandemic, many women now have second-trimester pregnancies because they could not find care in time.Across 37 countries, nearly 2 million fewer women received services between January and June than in the same period last year, Marie Stopes International says in a new report — 1.3 million in India alone. The organization expects 900,000 unintended pregnancies worldwide as a result, along with 1.5 million unsafe abortions and more than 3,000 maternal deaths.Those numbers “will likely be greatly amplified” if services falter elsewhere in Latin America, Africa and Asia, Marie Stopes’ director of global evidence, Kathryn Church, has said.The World Health Organization this month said two-thirds of 103 countries surveyed between mid-May and early July reported disruptions to family planning and contraception services. The U.N. Population Fund warns of up to 7 million unintended pregnancies worldwide.Lockdowns, travel restrictions, supply chain disruptions, the massive shift of health resources to combat COVID-19 and fear of infection continue to prevent many women and girls from care.A surge in teen pregnancies was reported in Kenya, while some young women in Nairobi’s Kibera slum resorted to using broken glass, sticks and pens to try to abort pregnancies, said Diana Kihima with the Women Promotion Center. Two died of their injuries, while some can no longer conceive.In parts of West Africa, the provision of some contraceptives fell by nearly 50% compared to the same period last year, said the International Planned Parenthood Federation.“I’ve never seen anything like this apart from countries in conflict,” said Diana Moreka, a coordinator of the MAMA Network that connects women and girls to care across 16 African countries. Calls have increased to their hotlines, including those launched since the pandemic began in Congo, Zambia and Cameroon. More than 20,000 women have called since January.Like others, Moreka predicts a coming baby boom in some parts of the world. “The pandemic ... has taken us many years backwards” in family planning services, she said.Some countries didn’t deem sexual and reproductive health services as essential under lockdown, meaning women and girls were turned away. Even after NGOs in Romania pressured the government to declare the services essential, many hospitals still weren’t providing abortions, said Daniela Draghici, a member of the IPPF European network’s executive committee.“The impact in some cases is like what used to happen to young women during Communism, to get an abortion from somebody who claims to be a medical provider ... and pray,” she said.In India’s megacity of Mumbai, one woman was unable to find a pregnancy testing kit after the lockdown started in March, and then couldn’t find transport to reach care in time, said Dr. Shewetangi Shinde, who attended to her in a public hospital. By then, medical abortion wasn’t an option since the pregnancy was too advanced.India listed abortions as essential services under lockdown but many weren’t aware, said Shinde, who is part of the India Safe Abortion Youth Advocates organization.The pandemic has highlighted how difficult it already was for many women to safely access abortion services, said Dr. Suchitra Dalvie, a gynecologist in Mumbai and coordinator of the Asia Safe Abortion Partnership.“All these people ... the marginalized groups, the vast invisible majority. This is how life is,” she said.In January, India began amending laws to allow certain women to obtain abortions up to 24 weeks instead of 20. But the pandemic interrupted it.No one expected the lockdown to continue for months, Dalvie said. Now many women face second-trimester abortions, which are more expensive and complicated, especially “because everyone who is involved needs to wear PPE.”Abortion access has improved in India, but the pandemic resulted in abortion pill shortages in several states surveyed by Foundation for Reproductive Health Services India. Only 1% of pharmacies in northern states like Haryana and Punjab had them, 2% in the southern state of Tamil Nadu and 6.5% in the central state of Madhya Pradesh. In Delhi it was 34%.Some contraceptives are still delayed by supply chain disruptions, said Chris Purdy, CEO of the DKT International social marketing organization for family planning products. Production is back online, but shipping routes are crowded and ports clogged with back orders, he said.Meanwhile, women’s health providers have scrambled to find solutions such as telemedicine, home deliveries of contraceptives and home-based medical abortions.But even now, “we’re hearing everywhere that numbers are down” as public health facilities struggle because thousands of staffers have been infected with the virus, said Marion Stevens, director of the South Africa-based Sexual & Reproductive Justice Coalition. Her group and others wrote to the health minister about women turned away from care.The real global measure of lockdowns’ effects will come when health ministries report annual data, experts say. But it will be incomplete. In Haiti, the health ministry reported a 74% drop in births at health facilities in May compared to the same period last year. Many women are delivering at home, but deaths there are not reported.“Small examples can tell us a lot,” said Nondo Ejano, coordinator for the Women’s Global Network for Reproductive Rights Africa. In Tanzania, he said, a major maternity hospital in Dar es Salaam was converted into a COVID-19 response center. “You can ask yourself,” he said of women seeking care, “where would they go?”At a school he visited last week in the town of Kigoma, five girls had become pregnant in the past few months. “One school. Five girls. Definitely the rate of pregnancy is up,” he said.“I feel like right now we just have a tip of the situation, and when lockdowns are lifted we will see things clearly,” said Phonsina Archane, a coordinator of the MAMA Network. “We should prepare ourselves for that time.”___Anna reported from Johannesburg.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

NASA's OSIRIS-REx mission and the asteroid Bennu have had a date planned for two years, and just after noon ET today, they finally got to meet face to face. OSIRIS-REx fired its thrusters for a small burn, putting it about 4.3 miles from Bennu, marking the end of its journey to the asteroid.The mission -- which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer -- is NASA's first asteroid sample return mission. It launched in September 2016 and will spend two years up close and personal with Bennu. First images of the asteroid from the spacecraft's perspective have appeared as it got closer and closer.On Tuesday, the spacecraft will fly within 5 miles of Bennu, which will help design future orbits and map the surface.Over the next year, OSIRIS-REx will survey the asteroid using five scientific instruments on board the spacecraft. These instruments will help it determine a safe location from which to collect a small sample from Bennu's surface that will be returned to Earth in September 2023."Bennu's low gravity provides a unique challenge for the mission," said Rich Burns, OSIRIS-REx project manager at NASA's Goddard Space Flight Center. "At roughly 0.3 mile in diameter, Bennu will be the smallest object that any spacecraft has ever orbited."The sample from Bennu, a near-Earth asteroid, could help scientists understand not only more about asteroids that could impact Earth but about how planets formed and life began.OSIRIS-REx has a camera suite, a laser altimeter for 3D mapping, a thermal emission spectrometer to take temperature and mineral content and spectrometers to measure X-rays, nearly infrared and visible light.An arm mechanism called TAGSAM will reach out to collect the sample from Bennu's surface, making contact with the asteroid for five seconds in July 2020. During this contact, the arm will use a nitrogen gas burst to stir up rock and other materials on the surface so it can capture them. There is enough nitrogen for three attempts if the first is unsuccessful.NASA said the estimated 2.1-ounce sample size equates to about 30 sugar packets worth of dirt and rocks.The arm has a full range of motion, with joints capable of movement comparable to shoulder, elbow and wrist joints. It was "flexed" in space for the first time on November 14."The TAGSAM exercise is an important milestone, as the prime objective of the OSIRIS-REx mission is to return a sample of Bennu to Earth," said Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, Tucson. "This successful test shows that, when the time comes, TAGSAM is ready to reach out and tag the asteroid."In 2021, it will be time for the spacecraft to essentially turn around and begin its two-year journey home. The sample will be packed into a capsule that will drop in the Utah desert in 2023.For two years after the return, the sample will be cataloged and analyzed. Afterward, 75% of the returned sample will remain at NASA's Johnson Space Flight Center so it can be used for more research by scientists from around the world.Why did NASA select Bennu out of the 780,000 known asteroids in our solar system?It was discovered in 1999, and scientists have been studying it ever since. The asteroid fits a number of criteria that make it intriguing and convenient.Bennu is relatively close to Earth, and its orbit even crosses that of our planet, making a close approach every six years. Though small asteroids can rotate very quickly, Bennu has a diameter just a bit bigger than the height of the Empire State Building and rotates relatively slowly, each 4.3 hours. This means OSIRIS-REx can match its velocity and touch down briefly.The asteroid could pass close to Earth, closer than the moon, in 2135, with even closer approaches possible in 2175 and 2195. A direct hit is unlikely, but the data gathered during this mission can help determine the best ways to deflect near-Earth asteroids.The asteroid is also old and well-preserved, full of valuable materials that may even contain clues about how life began. Bennu is essentially a leftover from the formation of our solar system billions of years ago, although some of the minerals inside it could be even older.This carbon-rich asteroid could be full of organic molecules, metals, platinum and even water -- the essential ingredients for life. It's because of objects like Bennu that these resources were delivered to Earth during its formation.Asteroids could even serve as fuel stations for robotic and human missions if we can unlock the hydrogen and oxygen inside them, NASA said.Bennu probably broke off of a larger asteroid in the asteroid belt between Mars and Jupiter a couple billion years ago. This knocked it through space until an orbit close to Earth locked it in place. And Bennu is believed to be a grouping of rocks held together by gravity rather than a single object.But its orbit drifts 0.18 miles each year toward the sun, and OSIRIS-REx will enable researchers to understand why and to predict Bennu's movements. This could also explain how it ended up as a near-Earth asteroid."The story of this asteroid is the story of the solar system," said Bashar Rizk, instrument scientist for OSIRIS-REx. "When we understand Bennu, we will understand something fundamental about our solar system."The-CNN-Wire 5356
