Corals switch skeleton as seawater changes
Leopards may not be able to change their spots, but corals can change their skeletons, building them out of different minerals depending on the chemical composition of the seawater around them
Higher carbon dioxide, lack of nitrogen limit plant growth
Earth's plant life will not be able to "store" excess carbon from rising atmospheric carbon dioxide levels as well as scientists once thought because plants likely cannot get enough nutrients, such as nitrogen, when there are higher levels of carbon dioxide, according to scientists publishing in this week's issue of the journal Nature
Geologists create 5-million-year climate record
Using chemical clues mined from ocean mud, Brown University researchers have generated the longest continuous record of ocean temperatures on Earth
Silent earthquakes may foreshadow destructive temblors
A team of American geoscientists is urging colleagues around the world to search for evidence of tiny earthquakes in seismically active areas, such as the Pacific Northwest, that are periodically rocked by powerful temblors of magnitude 8 and higher

'Scent of a woman' tells male redback spiders to find a mate
If men think finding a nice partner to settle down and raise children with is tough, consider the plight of the male Australian redback spider
Albatross study shows regional differences in ocean contamination
As long-lived predators at the top of the marine food chain, albatrosses accumulate toxic contaminants such as PCBs, DDT, and mercury in their bodies
3D model reveals secrets of metastasis
A cancer cell breaks away from a primary tumor and settles in a new location, where it once again divides
Undersea vehicles to study formation of gold and other precious metals on the Pacific Ocean floor
An international team of scientists will explore the seafloor near Papua New Guinea in the western Pacific Ocean later this month with remotely operated and autonomous underwater vehicles, investigating active and inactive hydrothermal vents and the formation of mineral deposits containing copper, gold and other commercially valuable minerals

: Scientists penetrate fossil magma chamber beneath intact ocean crust
Pacific Ocean, approximately 800 km west of Costa Rica. An international team of scientists aboard the research drilling ship JOIDES Resolution has --for the first time--recovered black rocks known as gabbros from intact ocean crust
Opening of passage may be tied to Antarctic colling
Ancient fish teeth are yielding clues about when Antarctica became the icy continent it is today, highlighting how ocean currents affect climate change
Impact of rainfall reaches to roots of mountains
The erosion caused by rainfall directly affects the movement of continental plates beneath mountain ranges, says a University of Toronto geophysicist — the first time science has raised the possibility that human-induced climate change could affect the deep workings of the planet
Honeybee decision making
When 10,000 honeybees fly the coop to hunt for a new home, usually a tree cavity, they have a unique method of deciding which site is right: With great efficiency they narrow down the options and minimize bad decisions
Animal brains "hard-wired" to recognize predator's foot movements
The reason people can approach animals in the wild more easily from a car than by foot may be due to an innate "life detector" tuned to the visual movements of an approaching predator's feet, says Queen's University psychologist Niko Troje
Could reducing global dimming mean a hotter, dryer world?
Despite concerns over global warming, scientists have discovered something that may have actually limited the impact of greenhouse gases in the atmosphere in recent years by reducing the amount of sunlight reaching the surface of the Earth
Cosmic dust in ice cores sheds light on earth's past
Each year nearly 40,000 tons of cosmic dust fall to Earth from outer space.
Slippery stretching explains ocean floor formation
For the first time, scientists have found regions of the earth's crust which are stretching apart to form new sea floor.
Autonomous unmanned aerial vehicles take to the skies to track pollutants
A research consortium funded by the National Science Foundation (NSF) and led by the Scripps Institution of Oceanography at the University of California, San Diego, has successfully sent a fleet of aerial drones through the pollution-filled skies over the Indian Ocean, thereby achieving an important milestone in the tracking of pollutants responsible for dimming Earth's atmosphere.
