...ermine where red tide is impacting both humans and sea life. "We are pleased to work with Carnegie Mellon researchers to improve our monitoring of red tide," said Richard P. Stumpf, an oceanographer with the NOAA National Ocean Service and a co-investigator for this project. "In fact, a huge, huge probl...

Vibrio bacteria could be a risk to fish as well as humans

...xtremely aggressive and could pose a great risk to sea animals, as disease is often caused by enzymes produced by bacteria." It is not yet clear to what extent these new vibrios affect marine animals in the wild. The next thrust of the work by Professor Austin and his team is to devise methods to minimi...

Locusts' built-in 'surface analysis' ability directs them to fly overland

...or example from mirrors or plastic surfaces." The sea reflects polarized light much more than dry land (which reflects mainly diffused, non-polarized light), enabling a distinction to be made between the two. "When the locusts are presented with a situation of choice between surfaces reflecting either p...

Globally 23 per cent of the world's population (1.2 billion people) live within 100 km of the coast and this figure is likely to increase to 50 per cent in the next twenty five years as people flock to coastal cities ?many...

"That's where the problem in identifying different species is greatest, where the bulk of the diversity of life is, including large numbers of undescribed forms." In those case...

...me temperatures. It grows and dwells in underwater sea volcanoes where temperatures reach more than 100 degrees Celsius, or that of boiling water. Occasionally, the organism is spewed out into near freezing deep-sea water. The NC State research, funded for two years and $400,000 by the NASA Institute fo...

A bug's life: Exceptional genomic stability yet rapid protein evolution in a carpenter ant mutualist

...arine worms, in echinoderms such as starfishes and sea urchins, and in specialized cells of insects such as aphids and tsetse flies. Many symbiotic relationships are obligate; neither the bacterium nor its host can live without the other. Wernegreen's group focused on the bacterium Blochmannia, which ha...
