Using the spread of infectious diseases as a model, a University of Utah researcher has shone new light on how humans first settled the islands of the Pacific some 3,500 years ago. Read about what his discoveries on EurekAlert! here.

Video: Research by Hebrew University of Jerusalem researchers has shed some light on exactly how octopuses manage their uniquely unusual biology. Check out some detailed videos of their work here and here, then read about it on EurekAlert!.

Iron-oxidizing bacteria found along Mid-Atlantic Ridge
Bacteria that live on iron were found for the first time at three well-known vent sites along the Mid-Atlantic Ridge. These bacteria likely play an important role in deep-ocean iron cycling, and are dominant members of communities near and adjacent to sulfur-rich hydrothermal vents prevalent along the Mid-Atlantic Ridge. This group of iron-oxidizing bacteria, Zetaproteobacteria, appears to be restricted to environments where iron is plentiful, suggesting they are highly evolved to utilize iron for energy.

A sea change for ocean resource management
Ocean ecosystems around the world are threatened by overfishing, extensive shipping routes, energy exploration, pollution and other consequences of ocean-based industry. Data exist that could help protect these vulnerable ecosystems, but current management strategies often can't react quickly enough to new information. San Diego State University biologist Rebecca Lewison and colleagues from several other academic, governmental and non-governmental organizations endorse a new approach called 'dynamic ocean management' in a paper published today in BioScience.

Scientists reconstruct evolutionary history of whale hearing with rare museum collection
The National Museum of Natural History's research team CT scanned fetal whale specimens from the museum's marine mammal collection to trace the development of fetal ear bones in 56 specimens from 10 different whale families. Their findings confirmed that changes in the development of ear bones in the womb paralleled changes observed throughout whale evolution, providing new insight about how whales made the dramatic evolutionary shift from land to sea and adapted to hearing underwater.

Farming a threat to endangered Chinese giant salamander
New research, led by international conservation charity Zoological Society of London, published in Oryx today shows that Chinese giant salamander (Andrias davidianus) farms risk the extinction of wild salamander populations instead of supporting their conservation.

Tracking sea turtles across hundreds of miles of open ocean
How sea turtles find their way across hundreds of miles of open ocean has been an enduring mystery of animal behavior. Reporting results of a study at UMass Amherst's Large Pelagic Research Center, Kara Dodge says 'Adult turtles can pinpoint specific nesting beaches even after being away many years.' Results of a new GPS tracking study now document their remarkable ability.

NASA looks inside and outside of Tropical Cyclone Pam
NASA's Terra satellite provided an outside look at Tropical Cyclone Pam while the RapidScat instrument that flies aboard the International Space Station provided an inside look at the surface winds generated by the storm. The GPM core satellite provided another inside look at Pam and provided data on where the heavy rainfall was occurring within the storm.

NASA sees a Tropical Storm Haliba 'sandwich'
Tropical Storm Haliba appeared to be the 'filling' in a sandwich between the Southern Indian Ocean islands of La Reunion and Mauritius in NASA satellite imagery because wind shear pushed the bulk of the storm's clouds between the islands.

Same forces as today caused climate changes 1.4 billion years ago
Natural forces have always caused the climate on Earth to fluctuate. Now researchers have found geological evidence that some of the same forces as today were at play 1.4 billion years ago.

Friction means Antarctic glaciers more sensitive to climate change than we thought
A new study by Caltech researchers finds that incorporating Coulomb friction into computer models increases the sensitivity of Antarctic ice sheets to temperature perturbations driven by climate change.

Tiny new fossil helps rewrite crab evolution, sheds lights on late Jurassic marine world
A paper in the journal Nature Communications co-written by NHM Crustacea curator Dr. Jody Martin describes a 150-million-year-old crab larva fossil specimen from southern Germany. The new fossil provides critical evidence for understanding the early rise of crabs.
