Researchers in the US fed mosquitoes blood contaminated with dengue virus and tested them for infection. Smaller-sized mosquitoes showed higher infection rates and greater potential to transmit the virus. Even a slight difference in the body sizes of Asian tiger and yellow fever

A team of scientists has come up with a new definition of seawater which is set to boost the accuracy of projections for oceans and climate.

Oceans help regulate the planet's weather by shifting heat from the equator to the poles. Changes in salinity and temperature are major forces driving global currents as well as circulation patterns from the surface to the seabed.

The Southern Ocean has proved more resilient to global warming than previously thought and remains a major store of mankind's planet-warming carbon dioxide, a study has found.

Oceans absorb a large portion of the extra CO2 released by mankind through burning fossil fuels or deforestation, acting as a brake on climate change, and the Southern Ocean is the largest of these "carbon sinks".

Oxygen threshold for dead zones needs revision ABOUT 246,000 square km of oceans

A city of brittle stars off the coast of New Zealand, an Antarctic expressway where octopuses ride along in a flow of extra salty water and a carpet of tiny crustaceans on the Gulf of Mexico sea floor are among the wonders discovered by researchers compiling a massive census of marine life.
