Researchers quantify toxic ocean conditions during major extinction 93.9 million years ago
A research team led by UC Riverside biogeochemists reports that oxygen-free and hydrogen sulfide-rich waters extended across roughly five percent of the ocean 93.9 million years ago -- far more than the modern ocean's 0.1 percent but much less than previous estimates for this event. Across this event, a major biological extinction in the marine realm took place. The new work shows that only portions of the ocean need to contain sulfide to greatly impact biota.

Crying wolf: Who benefits and when?
A crisis at work can bring out the best in colleagues, often inspiring more cooperation and self-sacrifice. A study from Indiana University and the University of Guelph has found that the benefits are not shared equally, with higher-ranking group members having the most to gain by perceived threats to the group.

Public wants labels for food nanotech -- and they're willing to pay for it
New research finds that people in the United States want labels on food products that use nanotechnology -- whether the nanotechnology is in the food or is used in food packaging. The research also shows that many people are willing to pay more for the labeling.

El Niño is becoming more active
A new approach to analyzing geological and biological clues from the past to reconstruct El Niņo activity during the past 600 years resolves disagreements and reveals that El Niņo has become more active in recent decades. The work, published in Climate of the Past by scientists from the University of New South Wales and the University of Hawaii International Pacific Research Center, may also help yield more accurate El Niņo projections with further global warming.

Breakthrough in study of aluminum should yield new technological advances
Researchers today announced a scientific advance that has eluded researchers for more than 100 years -- a platform to fully study and understand the aqueous chemistry of aluminum, one of the world's most important metals. It should open the door to significant advances in electronics and many other fields, ranging from manufacturing to construction, agriculture and drinking water treatment.

Scientists eye longer-term forecasts of US heat waves
Scientists have fingerprinted a distinctive atmospheric wave pattern high above the Northern Hemisphere that can foreshadow the emergence of summertime heat waves in the United States more than two weeks in advance. The new research, led by scientists at NCAR, could potentially enable forecasts of the likelihood of US heat waves 15-20 days out, giving society more time to prepare for these often-deadly events.

Aboriginal hunting practice increases animal populations
In Australia's Western Desert, Aboriginal hunters use a unique method that actually increases populations of the animals they hunt, according to a study co-authored by Stanford Woods Institute-affiliated researchers Rebecca and Doug Bird. The hunting method -- using fire to clear patches of land to improve the search for game -- also creates a mosaic of regrowth that enhances habitat.

Gold nanoparticles give an edge in recycling CO2
It's a 21st-century alchemist's dream: turning Earth's superabundance of carbon dioxide -- a greenhouse gas -- into fuel or useful industrial chemicals. Researchers from Brown University have shown gold nanoparticles can be tuned to selectively reduce CO2 into CO, an active carbon molecule that can be used to make alternative fuels and commodity chemicals. The key is maximizing the particles' long edges, which are the active sites for the reaction.
