Fish's use of electricity might shed light on human illnesses

Thu, 21 Jun 2018 14:10:54 EDT ~ African weakly electric fish, commonly called baby whales, use incredibly brief electrical pulses to sense the world around them and communicate with other members of their species. Part of that electrical mechanism exists in humans -- and by studying these fish, scientists may unlock clues about conditions like epilepsy. Find out more...

Marine reserves are vital -- but under pressure

Thu, 21 Jun 2018 10:14:14 EDT ~ A massive study of nearly 1800 tropical coral reefs around the world has found that marine reserves near heavily populated areas struggle to do their job -- but are a vast improvement over having no protection at all. Find out more...

Boring barnacles prefer the shallow life on coral reefs

Wed, 20 Jun 2018 17:46:04 EDT ~ Scientists have quantified how barnacles infest stony coral over a variety of conditions and reduce calcium carbonate on reefs. Coral reefs harbor diverse marine life and help prevent coastal erosion. Find out more...

When cozying up with would-be predators, cleaner shrimp follow a dependable script

Wed, 20 Jun 2018 17:46:01 EDT ~ It's a mystery how cleaner shrimp partner with would-be fish predators -- sometimes even climbing in their mouths -- without getting eaten. A new study reveals how the shrimp convinces fish not to eat them, and the fish conveys that it's a friend and not a foe. Find out more...

Beluga whales have sensitive hearing, little age-related loss

Wed, 20 Jun 2018 10:06:17 EDT ~ Scientists published the first hearing tests on a wild population of healthy marine mammals. The tests on beluga whales in Bristol Bay, Alaska, revealed that the whales have sensitive hearing abilities and the number of animals that experienced extensive hearing losses was far less than what scientists had anticipated. Find out more...

World's first known manta ray nursery

Tue, 19 Jun 2018 12:31:15 EDT ~ Located in the Gulf of Mexico off the coast of Texas at NOAA's Flower Garden Banks National Marine Sanctuary, the juvenile manta ray habitat is the first of its kind to be described in a scientific study. Find out more...

Deep-sea marine sponges may hold key to antibiotic drug resistance

Tue, 19 Jun 2018 12:30:13 EDT ~ FAU's Harbor Branch houses more than 1,000 strains of actinobacteria, one of the most prolific microbial groups for the production of natural products. Derived from sea sponges and other macro-organisms, several strains were identified for their potent antifungal activity, for anti-MRSA activity, and for both antifungal and antibacterial activities. A key finding was the identification of a strain that produced metabolites that are more potent than the bacterial antibiotic, vancomycin, against C. difficile. Find out more...

Coral reef 'oases' offer glimmer of hope

Mon, 18 Jun 2018 22:24:54 EDT ~ Scientists have discovered small communities of corals that are flourishing against the odds while so many around the world are dying. Find out more...

Local interventions boost coral's resilience to bleaching

Mon, 18 Jun 2018 22:24:30 EDT ~ Local conservation actions can significantly boost coral's resilience to, and recovery from, climate-induced thermal bleaching by reducing other energy-sapping stresses the coral faces, a new study finds. Scientists found they could reduce the extent of bleaching by half if they removed or reduced populations of coral-eating snails from affected reefs. The coral's recovery from bleaching was also enhanced. Find out more...

Rising sea temperatures threaten survival of juvenile albatross

Mon, 18 Jun 2018 10:26:05 EDT ~ Changes in sea surface temperature affect the survival of albatross during their first year at sea, resulting in a reduced population growth rate when temperatures are warmer than the current average, a new study has revealed. Find out more...
