New findings show a slow recovery from extreme global warming episode 55 million years ago
Most of the excess carbon dioxide pouring into the atmosphere from the burning of fossil fuels will ultimately be absorbed by the oceans, but it will take about 100,000 years. That is how long it took for ocean chemistry to recover from a massive input of carbon dioxide 55 million years ago, according to a…

Exploding star left no visible core
In 1987, earthbound observers saw a star explode in the nearby dwarf galaxy called the Large Magellanic Cloud. Astronomers eagerly studied this supernova–the closest seen in the past 300 years–and have continued to examine its remains. Although its blast wave lit up surrounding clouds of gas and dust, the supernova appears to have left no…

Patented technology captures carbon dioxide from power plants
Researchers from the University of California, Santa Cruz (UCSC), and Lawrence Livermore National Laboratory (LLNL) have invented a new method for controlling the emission of carbon dioxide from power plants. The technique, which mimics natural weathering processes, converts carbon dioxide gas into soluble compounds that can be disposed of in the oceans. Any strategy for…

UC Santa Cruz engineering students develop a coral reef monitoring system
Five senior engineering students at the University of California, Santa Cruz, are trying to push the limits of low-power wireless transmission to facilitate the monitoring of remote natural environments. The apparatus they are building will track conditions on coral reefs in distant locations and beam information back in real time to a land-based station. The…

Seismologists publish detailed analysis of the great Sumatra-Andaman earthquake
The great Sumatra-Andaman earthquake of December 26, 2004, was an event of stunning proportions, both in its human dimensions–nearly 300,000 lives lost–and as a geological phenomenon. The sudden rupture of a huge fault beneath the Indian Ocean unleashed a devastating tsunami. It was the largest earthquake in the past 40 years and was followed by…

Lacking a decent meal, killer whales reach for the popcorn
A study comparing the nutritional demands of killer whales with the caloric content of their prey has startling implications for the potential impact of these large predators on populations of other marine mammals. The study also raises issues relevant to the establishment of marine reserves and efforts to reintroduce large predators into terrestrial ecosystems, said…
