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!.

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.

Blue blood on ice -- how an Antarctic octopus survives the cold
An Antarctic octopus that lives in ice-cold water uses an unique strategy to transport oxygen in its blood, according to research published in Frontiers in Zoology. The study suggests that the octopus's specialized blood pigments could help to make it more resilient to climate change than Antarctic fish and other species of octopus.

Small eddies produce global effects on climate change
The increasing strength of winds over the Southern Ocean has extended its ability to absorb carbon dioxide, effectively delaying the impacts of global warming. New research published in the Journal of Physical Research found the intensifying wind over that ocean increased the speed and energy of eddies and jets. The increased movement and overturning of these eddies and jets has accelerated the carbon cycle and driven more heat into the deep ocean.

NASA sees Tropical Cyclone Haliba affecting La Reunion and Mauritius islands
Tropical Cyclone Haliba formed east of the island nation of Madagascar in the Southern Indian Ocean and is now affecting the La Reunion and Mauritius islands. NASA's Terra satellite passed over Haliba on March 9 and captured an image of the storm that showed the eastern quadrant was affecting the two smaller islands.

NASA eyes rainfall in newly formed Tropical Cyclone Pam
Tropical Cyclone Pam formed in the Solomon Islands in the Southern Pacific Ocean early on March 9. The Global Precipitation Measurement or GPM core satellite flew overhead and found some heavy rain occurring when it measured rainfall rates within the intensifying storm.

Scientists urge Brazilian government to stand strong on aquatic animal protections
A team of Brazilian scientists -- including Luiz Rocha, Ph.D., Associate Curator of Ichthyology at the California Academy of Sciences -- is raising awareness about impending conservation setbacks for Brazil's aquatic animals, calling for immediate fisheries management collaboration between the nation's public and private sectors. The scientists say Brazil can transform this moment of political turmoil into positive action -- and become a leader among developing countries facing widespread extinction of aquatic fauna.

Is the tasty blue crab's natural range creeping north?
Scientists have observed the Atlantic (or Chesapeake) blue crab, a commercially important species, moving north of its native range into the Gulf of Maine.
