New research shows sharks use their noses and bodies to locate smells

...ed two parallel, turbulent odor plumes – one using squid scent and the other a plain seawater control. Minimally turbulent ‘oozing’ sources of squid odor and seawater control were physically separated from sources of major turbulence by placing a br...

Role of noise in neurons

...this paper. Using detailed models of rodent and squid axons and stochastic simulations, the authors performed experiments, now published in PLoS Computational Biology, which took several months to simulate a few milliseconds of real time in the brain. They show how conduction along such thin axons is af...

Tracking sperm whales and jumbo squid

...s the successful tagging of sperm whales and jumbo squid swimming together off Mexico’s Pacific coast—the f... "Sperm whales (Physeter macrocephalus) and jumbo squid (Dosidicus gigas) are both major predators that spend much of their lives in one of the world’s larg...

Squid-inspired design could mean better handling of underwater vehicles

...rmation of vortex rings, much like those formed by squid and jellyfish to move themselves underwater. Vortex rings are formed when a burst of fluid shoots out of an opening, moving in one direction and spreading out as it curls back. The researcher's nature-inspired vortex generators could be used in ...

Squid skin reveals hidden messages

In the animal world, squid are masters of disguise. Pigmented skin cells enab...heir results suggest that it might be possible for squid to send concealed polarized signals to one other while staying camouflaged to fish or mammalian pred...

Why nerve cells work faster than the theory allows

...higher animals, such as cats or humans compared to squid or snails, is not only attributed to the higher number of neurons in the brains of these animals, but also to the manner in which the neurons process signals. To do so, these higher animals presumably use molecular mechanisms which the lower animals ...

Overfishing may drive endangered seabird to rely upon lower quality food

...rly a century before recent declines of anchovies, squid and rockfish. The researchers compared these historic samples with feathers they collected between 1998 and 2002 from 201 murrelets in the same region. The researchers had records of when and where all the feathers they sampled were obtained. Measu...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...jellyfish and benthic bristle worms, and the first squid and octopus ever found in the area. Scientists were also intrigued to discover among other things two species of sand flea-like crustaceans (amphipods) which, though familiar, had never before been found in an ice environment. Animal density far hi...
