Leading Experts to Share Vision for Untangling Global Food + Greenhouse Gas Conundrum at AAAS
Leading experts to share vision for untangling global food + greenhouse gas conundrum at AAAS
Several of the world’s top food researchers and scientists are gathering at AAAS on Sunday, Feb. 15, at 8:30am to share their unified vision for untangling one of the world’s stickiest problems: the fact that the development, production and delivery of food accounts for roughly one-third of global greenhouse gas emissions. The researchers will present state-of-the-art approaches and the latest science to address the issue.

Beneath the surface
Researchers from Copenhagen have developed a new model to explain the forming of rift zones. Rift zones are long cracks in the Earth's crust between the tectonic plates. They are generally over 1000km long, 30-100km wide and up to 10km deep. Over time they fill up with the remains of volcanic explosions and other sediment. The research results has great significance for oil and natural gas exploration, plus our general understanding of the forces beneath.

Scientists uncover a dramatic rise in sea level and its broad ramifications
Scientists have found proof in Bermuda that the planet's sea level was once more than 70 feet higher about 400,000 years ago than it is now. This had grave ramifications for the biodiversity on the planets coastlines and small islands.

Carbon acts like rustoleum around hydrothermal vents
The cycling of iron throughout the oceans has been an area of intense research for the last two decades. Oceanographers have spent a lot of time studying what has been affectionately labeled the Geritol effect ever since discovering that the lack of iron is a reason why phytoplankton grow lackadaisically in some of the most nutrient-rich surface waters. Just like humans, sometimes the ocean needs a dose of iron to function more effectively.

A wave of support for satellite research in Western Pacific
The Office of Naval Research awarded a $3.75 million grant to support satellite based research on internal waves and typhoons in the western Pacific Ocean. According to Hans C. Graber, co-director of the Center of Southeastern Tropical Advanced Remote Sensing at the University of Miami, this will allow scientists to look at how typhoons react when they encounter major ocean currents, large waves and topographical features in the Western Pacific Ocean to advance current methods of storm modeling and disaster mitigation.

Queen's energy partnership makes waves for UK
The likelihood of the UK being able to produce widespread energy from wave-generated power has been given a vital boost. Aquamarine Power Limited, a leading marine energy company, and Queen's University Belfast have agreed a new five year research partnership which will develop the next generation hydro-electric wave power converter. Already the partnership has created the Oyster wave power device. It is designed to capture the energy found in amplified surge forces in nearshore waves.

U of Minnesota-led study reveals mysteries of deep-sea nutrients
Iron dust, the rare but necessary nutrient for most life, can not only be washed into the ocean from rivers or blown out to sea, but it can bubble up from the depths of the ocean floor, a new study led by a University of Minnesota scientist shows.

A Zen discovery: Unrusted iron in ocean
Iron dust, the gold of the oceans and rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or -- a surprising new study finds -- float up uncorroded from the sea floor.

New equation of state of seawater
For 30 years, scientists have relied on a series of equations called International Equation of State of Seawater in their calculations. Now, based on new technology and oceanographic data, scientists have begun the process of adopting a new set of highly accurate and comprehensive formulas to provide much-needed adjustments and clarifications that are expected to be accepted internationally as early as 2010.

AIBS teams with University of Oklahoma on introductory biology experience project
The United States National Science Foundation has awarded a $398,020 Research Coordination Network grant to the University of Oklahoma to help university and college faculty members improve instruction in introductory biology courses. The American Institute of Biological Sciences (AIBS) partnered on the proposal and, through a sub-award, will provide programmatic staffing as well as expertise in building an online communication network for the RCN project's participants over the five-year grant period.

Sea level rise around North America upon collapse of Antarctic ice sheet to be higher than expected
University of Toronto geophysicists have shown that should the West Antarctic Ice Sheet collapse and melt in a warming world -- as many scientists are concerned it will -- it is the coastlines of North America and of nations in the southern Indian Ocean that will face the greatest threats from rising sea levels.

Sea level rise could be worse than anticipated
If global warming some day causes the West Antarctic Ice Sheet to collapse, as many experts believe it could, the resulting sea level rise in much of the United States and other parts of the world would be significantly higher than is currently projected, a new study concludes.

Caltech scientists lead deep-sea discovery voyage
Scientists from the California Institute of Technology and an international team of collaborators have returned from a month-long deep-sea voyage to a marine reserve near Tasmania, Australia, that not only netted coral-reef samples likely to provide insight into the impact of climate change on the world's oceans, but also brought to light at least three never-before-seen species of sea life.

Long-term recovery of reefs from bleaching requires local action to increase resilience
In the journal Estuarine, Coastal and Shelf Science, University of Miami Rosenstiel School of Marine and Atmospheric Science's Drs. Peter Glynn and Andrew Baker assess more than 25 years of data on reef ecosystems recovery from climate change-related episodes of coral bleaching. Co-authored by Dr. Bernhard Riegl of the National Coral Reef Institute, the study represents the first comprehensive review of long-term global patterns in reef recovery following bleaching events.

Ancient turtle migrated from Asia to America over a tropical Arctic
In Arctic Canada, a team of geologists from the University of Rochester has discovered a surprise fossil: a tropical, freshwater, Asian turtle. The find strongly suggests that animals migrated from Asia to North America not around Alaska, as once thought, but directly across a freshwater sea floating atop the warm, salty Arctic Ocean.
