Ancient ocean currents may have changed pacing and intensity of ice ages
In a new study in Science, researchers find that the deep ocean currents that move heat around the globe stalled or even stopped about 950,000 years ago, possibly due to expanding ice cover in the north. The slowing currents increased carbon dioxide storage in the ocean, leaving less in the atmosphere, which kept temperatures cold and kicked the climate system into a new phase of colder but less frequent ice ages, they hypothesize.

Scientists find the shocking truth about electric fish
Scientists have found how the electric fish evolved its jolt. Writing June 27, 2014, in the journal Science, a team of researchers led by Michael Sussman of the University of Wisconsin-Madison, Harold Zakon of the University of Texas at Austin and Manoj Samanta of the Systemix Institute in Redmond, Wash., identifies the regulatory molecules involved in the genetic and developmental pathways that electric fish have used to convert a simple muscle into an organ capable of generating a potent electrical field.

Managing specialized microbes to clean stubborn chemicals from the environment
In a series of new studies, Anca Delgado, a researcher at Arizona State University's Biodesign Institute, examines unique groups of microorganisms, capable of converting hazardous chlorinated chemicals like trichloroetheene into ethene, a benign end product of microbial biodegradation.

Wild Connection: What Animal Mating and Courtship Tell Us About Human Relationships
Sex-crazed turtles, confused bees, and cheating swans. These are just a few of the things animal behavior expert Dr. Jennifer Verdolin discusses in this new book that blends humor and science to show the similarities between humans and animals when it comes to dating and relationships.

Changes in forage fish abundance alter Atlantic cod distribution, affect fishery success
A shift in the prey available to Atlantic cod in the Gulf of Maine that began nearly a decade ago contributed to the controversy that surrounded the 2011 assessment for this stock. A recent study of how this occurred may help fishery managers, scientists, and the industry understand and resolve apparent conflicts between assessment results and the experiences of the fishing industry.

Invasive watersnakes introduced to California may pose risk to native species
Watersnakes, commonly seen in the lakes, rivers and streams of the eastern United States, are invading California waterways and may pose a threat to native and endangered species in the state, according to a University of California, Davis, study.

Are fish near extinction?
A new study from Tel Aviv University has uncovered the reason why 90 percent of fish larvae are biologically doomed to die mere days after hatching. This understanding of the mechanism that kills off the majority of the world's fish larvae may help find a solution to the looming fish crisis in the world.

Study links Greenland ice sheet collapse, sea level rise 400,000 years ago
A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some four to six meters.

Can coral save our oceans?
New research from Tel Aviv University has uncovered the protective properties of soft coral tissue, which proved resilient when exposed to declining oceanic pH levels. The study provides insight into the changing face of coral reefs threatened by dropping oceanic pH levels as a result of climate change and may provide a new approach toward preserving the harder, calcified reef foundations.

Young researcher discovers source of disco clams' light show
The disco clam was named for the rhythmic, pulsing light that ripples along the lips of its mantle. UC Berkeley graduate student Lindsey Dougherty was fascinated the first time she saw the clam, and set out to investigate the reflective material on its lips and why it flashes. She reports that the mirror is actually a highly reflective, densely packed layer of silica spheres a mere 340 nanometers across never before seen in animals.
