An assortment of saber-toothed cats, hyenas, an extinct 'bear-dog', ancestors of the red panda and several other carnivores died under unusual circumstances in a Spanish cave near Madrid approximately 9-10 million years ago. It now appears that the animals may have entered the cave intentionally and been trapped there, according to research published May 1 in the open access journal PLOS ONE by Soledad Domingo from the University of Michigan and colleagues from other institutions. http://phys.org/news286644724.html Other Sciences Wed, 01 May 2013 17:00:13 EST news286644724 The vast region of Africa known as the Sahel will descend into large-scale drought, famine, war and terrorist control if immediate, coordinated steps are not taken to avert the perfect storm of climate change and the most rapidly growing population in the world, a group of experts from the University of California, Berkeley, and the African Institute for Development Policy (AFIDEP), concluded in a report released today, which summarizes findings from the first international, multidisciplinary meeting on the region. http://phys.org/news284801513.html Space & Earth Wed, 10 Apr 2013 08:32:02 EST news284801513 Although immigration to the United States from Latin American countries, particularly Mexico, has captured much public attention, immigrants who move between countries in Latin America have more difficulty than those moving to the United States. http://phys.org/news280680756.html Other Sciences Thu, 21 Feb 2013 14:55:45 EST news280680756 What do nonvoters look like, can they be categorized and why don't they vote?

Previous studies have shown that men with younger wives live longer. While it had long been assumed that women with younger husbands also live longer, in a new study Sven Drefahl from the Max Planck Institute for Demographic Research (MPIDR) in Rostock, Germany, has shown that this is not the case. Instead, the greater the age difference from the husband, the lower the wife's life expectancy. This is the case irrespective of whether the woman is younger or older than her spouse. http://phys.org/news192877463.html Medicine & Health Wed, 12 May 2010 10:25:45 EST news192877463 People in developed nations are living in good health as much as a decade longer than their parents did, not because aging has been slowed or reversed, but because they are staying healthy to a more advanced age. http://phys.org/news188655254.html Other Sciences Wed, 24 Mar 2010 14:00:22 EST news188655254 (PhysOrg.com) -- The role of a mother in African families is even more essential to the well-being of a child than the role played by the breadwinner father, according to a study published in the latest issue of the journal Demography. http://phys.org/news187897273.html Other Sciences Mon, 15 Mar 2010 19:30:01 EST news187897273 (PhysOrg.com) -- A new Cornell study of online poker seems counterintuitive: The more hands players win, the less money they're likely to collect - especially when it comes to novice players. http://phys.org/news182532748.html Other Sciences Tue, 12 Jan 2010 15:38:16 EST news182532748 Every 10 years, the U.S. Census Bureau undertakes a mammoth task: counting all of the people living in the United States and recording basic information such as age, sex, and race.
