Residents in the poorest counties in the U.S. face a life expectancy up to decade shorter than their counterparts in the wealthiest areas, according to a study published in the American Journal of Public Health.

    Researchers from East Tennessee State University wanted to better understand how socioeconomic status was associated with heath outcomes. To find out they divided the country's 3,141 counties into 50 new 'states' (with 2 percent of the counties in each) based on household income as opposed to geographic proximity (接近).

    The researchers broke down the data by county since they found state-level data may hide some 'impact of socioeconomic differences on both the best-off and worst-off counties.' They then examined health data from the wealthiest and poorest 'states' (top and bottom 2 percent) to see how residents differed on factors like smoking, clinical care and excessive drinking. Researchers found that there was nearly a 10-year gap in the life expectancy of men with an average of 79.3 years in the wealthy counties compared to 69.8 years in the poorest. For women, the difference was slightly less - 83 years in the wealthiest counties and 76 years in the poorest.

    The study authors caution that while they found a connection between socioeconomic status and health outcomes, they did not analyze cause and effect. But they suggest that the data shows how policy makers should not just focus on state-wide initiatives (主动性) but more targeted efforts to help those most at risk. “With limited resources, methods of pinpointing the poorest counties can assist in the allocation of resources and programs to those communities that are in the greatest need,'' the study authors wrote.

    The softshell turtle species is officially listed as endangered by the IUCN Red List. Scientists long thought softshell turtles were extinct in the Cambodian part of the Mekong River until they discovered some stragglers (掉队者) in the early 2000s.

    The species had quite a wide historical range across Asia, but much of that range is now completely gone. Much of the turtle's habitat in Southeast Asia have disappeared due to urban and industrial development along the Mekong River. The sand where turtles multiply is routinely carried away for use in construction projects, while fishing nets lift up hatchlings. People also take turtles and their eggs to sell for food.

    Initial surveys in 2003 and in 2007 found two small populations of the softshell turtles along a 30-mile stretch (水域) of the Mekong River. Since then, conservation groups have worked with local communities and officials to increase the wild population of these endangered turtles, including a program to hire former egg collectors to help search for and protect nests instead of harvesting the eggs.

    For the last decade, WCS, Conservation International, the Turtle Survival Alliance and local groups have worked to protect turtle nests. Their goal is to ensure eggs will multiply and hatch, and that baby turtles grow strong enough to eventually take care of themselves in the wild.

    A team recently released 150 hatchlings back into their natural habitat, bringing the total to more than 7,700 baby turtles in the past 10 years.

    Nola (August 21, 1974-November 22, 2015)was a northern white rhino(犀牛) who lived at the San Diego Zoo Safari Park near Escondido, California. At her death, she was one of only four remaining northern white rhinos in the world. The other three lived in Kenya. World Rhino Day, held on September 2, is to raise awareness(意识) of the less than 30, 000 other rhinos left on Earth.

    "Rhinos need our help today, not tomorrow," Nola's lead keeper Jane Kennedy said. "Last year we lost over 1, 200 rhinos just in South Africa. If we continue to lose more than 1, 000 rhinos a year, in 10 to 20years all the rhinos on the planet will be gone. "

    "Unfortunately, most animals are in danger of dying out because of humans," Kennedy says. "Humans have either poached animals, or because there are over seven billion of us, we've taken up too much of the world's resources". Poachers illegally hunt rhinos for their horns. They sell the horns for thousands of dollars per pound, to be used for art, jewelry, and decorations. Experts believe that one rhino is poached every eight hours.

    In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell (细胞) samples from more than 8, 000 different types of animals, including the northern white rhino. Scientists hope that by studying the rhino cells, they will get greater understanding of it, and will find ways to increase its numbers.

    Jane Kennedy describes World Rhino Day as "a celebration of rhinos along with an awareness campaign(活动)for everybody across the world to know that rhinos need our help. "At the San Diego Zoo, children and adults are welcome to visit and speak with zookeepers to learn about rhinos. But you don't have to live in San Diego to celebrate World Rhino Day. It is observed around the world, with zoos and wildlife parks holding special events and programs to teach people about rhinos, and enable them to see the animals up close.
