(Phys.org) —An Iowa State University sociologist is not surprised by a recent U.S. Census Bureau report showing a spike in the number of unmarried women giving birth. According to the report, nearly 36 percent of babies born in 2011 were to single mothers. Susan Stewart, an associate professor, says there are several factors that influence this rate, including the recent recession. http://phys.org/news287389444.html Other Sciences Fri, 10 May 2013 07:24:30 EST news287389444 Global population data spanning the years from 1900 to 2010 have enabled a research team from the Autonomous University of Madrid to predict that the number of people on Earth will stabilise around the middle of the century. The results, obtained with a model used by physicists, coincide with the UN's downward forecasts. http://phys.org/news284291377.html Other Sciences Thu, 04 Apr 2013 10:49:51 EST news284291377 South Africa's white rhino population will begin to decline by 2016 if the current rate of poaching continues, authorities warned on Friday, following the killing of scores of the creatures this year. http://phys.org/news281951402.html Biology Fri, 08 Mar 2013 07:50:20 EST news281951402 South Africa is exploring the legal trade of rhino horn to counter a poaching bloodbath that has surged despite tighter security controls, the environment minister said Thursday. http://phys.org/news281278409.html Biology Thu, 28 Feb 2013 13:30:01 EST news281278409 Improving water supplies in rural African villages may have negative knock-on effects and contribute to increased poverty, new research published today has found. http://phys.org/news272130052.html Other Sciences Wed, 14 Nov 2012 18:10:06 EST news272130052 Understanding how a species battles to sustain itself in a challenging habitat is a cornerstone of ecological research; now scientists have applied this approach to science itself to discover why women are being driven out of academia.

According to the findings, career development issues can come to dominate the long-term life plans of women who have lost their job. The study also points toward additional socio-economic factors that can impact on birth rates over the long term. http://phys.org/news169738100.html Other Sciences Mon, 17 Aug 2009 14:40:02 EST news169738100 (AP) -- Conservationists raised the alarm Thursday for Zimbabwe's rare rhinos after a sharp increase in poaching because of a breakdown of law enforcement in this troubled southern African country. http://phys.org/news159118915.html Biology Thu, 16 Apr 2009 16:43:10 EST news159118915 (AP) -- More babies were born in the United States in 2007 than any year in the nation's history, topping the peak during the baby boom 50 years earlier, federal researchers reported Wednesday. http://phys.org/news156597406.html Medicine & Health Wed, 18 Mar 2009 16:19:59 EST news156597406 The nation's preterm birth rate declined slightly in 2007 - a finding that the March of Dimes hopes will prove to be the start of a new trend in improved maternal and infant health. http://phys.org/news156603387.html Medicine & Health Wed, 18 Mar 2009 13:57:02 EST news156603387 Thirty years ago last summer, the world's first "test-tube" baby was born, and since then more than 1 million infants have been successfully conceived through in vitro fertilization (IVF), the technique in which a woman's eggs and man's sperm are fertilized in a laboratory and then implanted in the mother's womb. http://phys.org/news151176421.html Medicine & Health Wed, 14 Jan 2009 17:27:01 EST news151176421 New government statistics confirm that the decades-long rise in the United States preterm birth rate continues, putting more infants than ever at increased risk of death and disability. http://phys.org/news150559656.html Medicine & Health Wed, 07 Jan 2009 14:07:36 EST news150559656 Long established medical interventions to help couples with infertility problems do not seem to improve fertility, according to a study published on bmj.com today.
