2009 AAAS Annual MeetingSynthetic biology can help extend anti-malaria drug effectiveness Synthetic biology can not only provide a simple and much less expensive means of making artemisinin, the most powerful anti-malaria drug in use today, but can also help extend the drug's effectiveness. Bundling microbial-based artemisinin as part of an anti-malarial drug "cocktail" rather than selling it as a monotherapy should delay or even prevent malaria parasites from developing resistance.

2009 AAAS Annual MeetingAnthropologist's studies of childbirth bring new focus on women in evolution Contrary to the TV sitcom where the wife experiencing strong labor pains screams at her husband to stay away from her, women rarely give birth alone. Assisted birth has likely been around for millennia, possibly dating as far back as 5 million years ago when our ancestors first began walking upright, according to University of Delaware paleoanthropologist Karen Rosenberg. She says that social assistance during childbirth is just one aspect of our evolutionary heritage that makes us distinctive as humans. Contact: Tracey Bryant

2009 AAAS Annual MeetingArizona State's Lawrence Krauss predicts a 'miserable future' for our universe Our picture of the universe has changed more in the past decade or so than it did in the past century. The changes have had a significant effect upon our understanding of the future of the universe and life within it. Contact: Nikki Staab

2009 AAAS Annual MeetingState of the steric sea level rise, 1955-2003 Based on a detailed analysis of ocean vertical temperature profiles for the 1955-2008 period, Sydney Levitus, lead author, talks about the change of global average sea level induced by the observed warming of the world ocean during the past 53 years. The warming of the world ocean is consistent with the amount of warming expected as a result of the observed increase in greenhouse gases in earth's atmosphere.

2009 AAAS Annual MeetingAccelerating urbanization presents daunting engineering challenge Ensuring the world's fast-growing urban regions function efficiently in the future will demand a much more complex public infrastructure than anything yet designed. Engineers are facing challenges of not only dealing with information, communication and public-utility systems that are themselves becoming more complicated, but must develop the technological advances necessary to effectively interconnect and control these systems on larger scales than anything achieved to date.

2009 AAAS Annual MeetingCosmologists aim to observe first moments of universe During the next decade, a delicate measurement of primordial light could reveal convincing evidence for the popular cosmic inflation theory, which proposes that a random, microscopic density fluctuation in the fabric of space and time gave birth to the universe in a hot big bang approximately 13.7 billion years ago.

2009 AAAS Annual MeetingFood counterfeiting, contamination outpace international regulatory systems Intentionally contaminated Chinese milk killed several children and sickened 300,000 more, causing concern around an increasingly connected world economy. Demand for inexpensive products virtually guarantees future repeats of food adulteration and counterfeiting from overseas, Michigan State University researchers said, as trade volumes overwhelm regulatory oversight.

2009 AAAS Annual MeetingCollege science requirements keep US ahead of world, MSU researcher argues Despite frequent warnings of the inadequacy of education in the United States, citizens here are still among the world's most scientifically literate, a Michigan State University researcher said. You can thank those general education requirements that force English majors to sit through biology classes and budding engineers to read Hemingway, Jon Miller said. Contact: Mark Fellows

2009 AAAS Annual MeetingCarbon accounting from atmospheric measurements -- the aircraft perspective The NOAA/ESRL aircraft network has embarked on many recent intensive efforts to explore processes at the 10 to 100 km scale. In particular, air mass-following experiments using small aircraft can be used to observe ground emission or uptake of CO2 in a single air mass as it moves across an agricultural or urban landscape. The net result is a validation of ground-level emissions estimates by direct measurements of changes in atmospheric CO2.

2009 AAAS Annual MeetingPast trends in hurricane activity and inferences for the future Knutson will discuss analysis of historical ship track records suggesting that reporting coverage of was too sparse to detect all tropical storms and therefore tropical storm counts do not have any significant trends between 1878 and 2006.

2009 AAAS Annual MeetingUsing satellites to monitor climate change: Progress and challenges Many of the early research and meteorological satellites were either not designed for climate-quality measurements, or were not succeeded at the end of their lifetimes. The resulting patchwork of quality data has required extraordinary scientific effort to yield credible climate information.

2009 AAAS Annual MeetingPenn genetics researcher presents on evolutionary history of modern humans in Africa Sarah A. Tishkoff, PhD, David and Lyn Silfen University Associate Professor, will present "Evolutionary History of Modern Humans in Africa. In honor of Darwin's 200th birthday on February 12, Tishkoff's talk will focus on the process of evolution due to natural selection using examples from recent human evolution. Contact: Karen Kreeger

2009 AAAS Annual MeetingLeading edge facility to strip history bare A new facility opening later this year at the Diamond synchrotron is set to revolutionize world heritage science. A new research platform soon to be available at the leading UK science facility, Diamond Light Source, will help uncover ancient secrets that have been locked away for centuries. For the first time ever, cultural heritage scientists will be able to scan and image large relics and artifacts up to two tons in weight in incredible precision. Contact: Sarah Bucknall

2009 AAAS Annual MeetingSynthetic biology yields clues to evolution and the origin of life Researchers in the field of synthetic biology are still a long way from being able to assemble living cells from scratch in the laboratory. But according to UC Santa Cruz biochemist David Deamer, their efforts are yielding clues to the mystery of how life began on Earth.

2009 AAAS Annual MeetingWhen fish farms are built along the coast, where does the waste go? Commercial fish pens are placed in the open waters of oceans and bays with no reliable method of predicting where the waste plume will be carried by winds, currents and tides. This can lead to damage to fragile coastline environments. As state and federal regulators begin to draw up rules for fish pens, Stanford's fluid dynamics modeling system can provide answers.

2009 AAAS Annual Meeting Journal of Cognitive NeuroscienceResearchers shed new light on connection between brain and loneliness Social isolation affects how people behave as well as how their brains operate, a new shows. The research, presented Sunday at a briefing at the annual meeting of the American Association for the Advancement of Science, is the first to use fMRI scans to study connections between perceived social isolation (or loneliness) and activity in the brain. Combining fMRI scans with data relevant to social behavior is part of an emerging field examining brain mechanisms.

2009 AAAS Annual MeetingScientist models the mysterious travels of greenhouse gas The global travel logs of greenhouse gases are based on atmospheric sampling locations sprinkled over the Earth and short towers that measure the uptake or release of carbon from a small patch of forest. But those measurements don't agree with current computer models of how plants and soils behave. A University of Michigan researcher is developing a unique way to reconcile these crucial data.
