News briefing at 2010 AAAS meeting More than three million children have been born as a result of assisted reproductive technologies since the birth of the first "test tube baby" in 1978. While the majority of these children are healthy and normal, as a group they are at greater risk of certain kinds of birth defects and being low birth weight, which is associated with obesity, hypertension and type 2 diabetes later in life. Carmen Sapienza, a geneticist at Temple University School of...

MSU professor says EROI not enough A Michigan State University professor says if the world is to make better decisions when it comes to developing new energy sources, it needs to have better methods of measuring progress toward its energy goals. Just how well are we doing at developing alternatives to fossil fuels? Speaking at this year's meeting of the American Association for the Advancement of Science, Bruce Dale said that appropriate metrics are needed in order to gauge our progress...

Protecting vulnerable reproduction sites key to long-term health of fish populations Once described by Jacques Cousteau as the "world's aquarium," the marine ecosystems of the Gulf of California are under threat. Destructive new fishing methods are depleting the sea's habitats, creating areas that are ghosts of their former existences. But, as Octavio Aburto-Oropeza of Scripps Institution of Oceanography at UC San Diego will describe during a presentation at the 2010 American Association for...

UA researchers find naps are an integral part of learning for infants, helping the developing brain retain new information Anyone who grew up in a large family likely remembers hearing "Don't wake the baby." While it reinforces the message to older kids to keep it down, research shows that sleep also is an important part of how infants learn more about their new world. Rebecca Gomez, Richard Bootzin and Lynn Nadel in the psychology department at the University of Arizona in Tucson found that...

Cultural views of evolution can have important ethical implications, says a Duke University expert on theological and biomedical ethics. Because the popular imagination filters science through cultural assumptions about race, cultural history should be an essential part of biomedical conversations. Amy Laura Hall, associate professor of Christian ethics at Duke University, argues that many popularized ideas about evolution assume that some human groups are more evolved than other human...

Influenza surveillance mechanisms in Mexico were adequate during the fast-spreading H1N1 outbreak in 2009, yet Mexico did not have the infrastructure to quickly identify the emergence of this novel strain, according to an Arizona State University (ASU) epidemiologist. Carlos Castillo-Chavez, director of ASU's Mathematical, Computational and Modeling Sciences Center in the College of Liberal Arts and Sciences, will take a close look at factors impacting the influenza dynamics within Mexico...
