Immigrants cost the health care system less than US-born Americans: Study

Health
Slightly over half of Americans — 52 percent — believe that immigrants are a financial burden on the U.S. healthcare system, and two thirds believe that undocumented immigrants should not be eligible for social services provided by state and local governments. A study published Thursday in the International Journal of Health Services finds that immigrants actually use far less healthcare resources than non-immigrants, and may actually subsidize the health care of U.S. citizens. Researchers at Harvard Medical School and Tufts University assessed all peer-reviewed studies since 2000 related to healthcare costs by immigrants in the United States. The authors found that across all age groups, immigrants’ overall healthcare costs were one-half to two-thirds those of people ...
African killifish matures faster than any vertebrate species

African killifish matures faster than any vertebrate species

Science
Aug. 6 (UPI) -- New research suggests no vertebrate species matures as quickly as Africa's turquoise killifish. The tiny fish persist for most of the year as diapausing embryos buried in savannah sediments. Like dormant plant seeds, the embryos suspend their development until rains arrive. When rains finally do arrive and water pools in small depressions, the fish are on the clock. They must hatch, grow and reproduce before the pools dry up. When scientists surveyed turquoise killifish, Nothobranchius furzeri, populations in southern Mozambique, they found the tiny fish hatch, grow and begin reproducing in just two weeks. "We guessed that some populations of this species could achieve very rapid growth and sexual maturation under particular conditions," Martin Reichard, researcher at the...
Corporate governance standards at PSBs much better than ever before, says Goyal

Corporate governance standards at PSBs much better than ever before, says Goyal

Finance
Emphasising that corporate governance standards being followed by public sector banks are much better than ever before, Finance Minister Piyush Goyal today said the government has stopped the "phone-call thing" coming in from Delhi to the banks. In an apparent dig at the previous UPA regime, Goyal said that not a single phone call would go to "give a loan, to address a loan, to restructure a loan or to settle a loan". Against the backdrop of high amounts of stressed assets in the banking system, the ruling BJP had alleged that earlier, banks used to get calls from the higher ups in the national capital to provide loans to various entities. Prime Minister Narendra Modi had also made references to it while replying to the debate on no-confidence motion in the Lok Sabha last month. Goyal told...
More than a quarter of the globe is controlled by indigenous groups

More than a quarter of the globe is controlled by indigenous groups

Science
July 16 (UPI) -- New research suggests the role of indigenous people in land management and conservation is under appreciated. According to the new survey, indigenous groups own, use or have management rights over more than a quarter of Earth's land surface. Indigenous groups control approximately 14.6 million square miles. Roughly 40 percent of Earth's protected terrestrial land consists of acreage controlled by indigenous groups. The new research, published this week in the journal Wildlife Conservation Society, highlights the importance of indigenous groups to land conservation around the globe. "Understanding the extent of lands over which indigenous peoples retain traditional connection is critical for several conservation and climate agreements," Stephen Garnett, a professor at Cha...
Humans may have left Africa earlier than thought

Humans may have left Africa earlier than thought

Technology
Primitive humans may have ventured out of Africa earlier than previously thought, new evidence suggests.  Stone tools found during an excavation in China are thought to be about 270,000 years older than the previous earliest evidence of a human presence outside Africa.Chinese and British researchers believe the tools were made by another member of the homo evolutionary group, rather than homo sapiens, as much as 2.1 million years ago.Until now, the oldest evidence of human-like creatures outside the continent came from 1.8 million-year-old artefacts and skulls found in Dmanisi in Georgia.The newly discovered artefacts were found on a plateau north of the Qinling mountains and include several chipped rocks, fragments and hammer stones.The research, published in the jour...
