Out of Africa: Did humans migrate quickly and all-at-once or in phases based on weather?
Considerable debate surrounds the migration of human populations out of Africa. Two hypotheses predominate: (1) human populations expanded rapidly from Africa to southern Asia via the coastlines of Arabia approximately 50,000 to 60,000 years ago; or (2) dispersal into the Arabian interior began much earlier (approximately 75,000 to 130,000 years ago) during multiple phases, when increased rainfall provided sufficient freshwater to support expanding populations.

Probiotic toxin fights coldwater disease in rainbow trout
The rainbow trout is a work of art but when the freshwater fish falls prey to Coldwater Disease, its colorful body erodes into ragged ulcers. The bacterial infection can kill up to 30 percent of hatchery stock and causes millions in economic loss. Now, scientists at University of Idaho and Washington State University have found a simple and effective method to combat Coldwater Disease using some of the trout's own intestinal bacteria as probiotics.

NASA covers Tropical Cyclone Lam's landfall in northern territory
As Tropical Cyclone Lam made landfall in Australia's Northern Territory on Feb. 19 (EST), NASA satellites and instruments gathered data on the storm's structure and behavior. Two instruments aboard NASA's Aqua satellite, NASA-JAXA's GPM core satellite, the RapidScat instrument aboard the International Space Station provided information to forecasters before and after Lam came ashore.

Study outlines impact of tsunami on the Columbia River
Engineers at Oregon State University have completed one of the most precise evaluations yet done about the impact of a major tsunami event on the Columbia River, what forces are most important in controlling water flow and what areas might be inundated.

Size matters in the battle to adapt to diverse environments and avoid extinction
By examining research on global patterns of amphibian diversification over hundreds of millions of years, De Lisle and Rowe discovered that 'sexually dimorphic' species -- those in which males and females differ in size, for example -- are at lower risk of extinction and better able to adapt to diverse environments.

Sardines move north due to ocean warming
Sardines, anchovies and mackerels play a crucial role in marine ecosystems, as well as having a high commercial value. However, the warming of waters makes them vanish from their usual seas and migrate north, as confirmed by a pioneering study analyzing 57,000 fish censuses from 40 years. The researchers warn that coastal towns dependent on these fishery resources must adapt their economies.
