Sea Lions Found To Have A Type Of Epilepsy Similar To That In Humans
2014-03-18 14:25:42

Lee Rannals for redOrbit.com - Your Universe Online Scientists at Stanford University School of Medicine found a form of epilepsy in sea lions that is similar to one found in humans. In a published paper in the Journal of Comparative Neurology, the team wrote that California sea lions exposed to a toxin in algae develop a form of epilepsy similar to a temporal lobe epilepsy. Hundreds of sea lions wash up along the California coast each year suffering from seizures that have been...

FDA may need to reconsider what levels of domoic acid in shellfish and fish are safe A chemical that can accumulate in seafood and is known to cause brain damage is also toxic to the kidneys, but at much lower concentrations. The findings, which come from a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN), suggest that officials may need to reconsider what levels of the toxin are safe for human consumption. The world's oceans contain algae...

Growth Of Toxic Algae Caused By Nitrogen From Pollution And Natural Sources

San Francisco State University Nitrogen in ocean waters fuels the growth of two tiny but toxic phytoplankton species that are harmful to marine life and human health, warns a new study published in the Journal of Phycology. Researchers from San Francisco State University found that nitrogen entering the ocean -- whether through natural processes or pollution -- boosts the growth and toxicity of a group of phytoplankton that can cause the human illness Amnesic Shellfish Poisoning....

Harmful algal blooms that affect seafood on the rise in California With toxic algal blooms – which can increase the amount of harmful toxins in the shellfish that California residents consume – ramping up in frequency and severity locally, scientists at USC have developed a new algae monitoring method in hopes of one day being able to predict when and where toxic "red tides" will occur. "We have, what we fear, is a hotspot here for some types of toxic algal blooms," said...

Findings, which contradict a commonly-proposed approach to reducing global climate change, are published in Proceedings of the Natural Academy of Sciences LSU's Sibel Bargu, along with her former graduate student Ana Garcia, from the Department of Oceanography and Coastal Sciences in LSU's School of the Coast & Environment, has discovered toxic algae in vast, remote regions of the open ocean for the first time. The recent findings were published in the Nov. 8 edition of one of the most...

A team of marine scientists has found that toxin-producing algae once thought to be limited to coastal waters are also common in the open ocean, where the addition of iron from natural or artificial sources can stimulate rapid growth of the harmful algae. The new findings, reported this week in the Proceedings of the National Academy of Sciences, add to concerns about proposals to use iron fertilization of the oceans as a way to combat global warming. Blooms of diatoms in the genus...

Adding iron to ocean water, believed to be an effective way to absorb carbon dioxide and fight global climate change, could actually be poisoning marine life, claims a new study released Monday. Researchers from the University of Western Ontario, analyzed water samples obtained from open-ocean tracts in the northern Pacific Ocean. They found that the iron stimulated the growth of Pseudo-nitzschia, a type of algae which releases a toxic substance called domoic acid -- a neurotoxin that can...

Scientists discover clues into human diseases by studying dolphins in a changing ocean A panel of governmental, academic and non-profit scientists speaking today at the annual meeting of the American Association for the Advancement of Science (AAAS) unveiled research suggesting that diseases found in dolphins are similar to human diseases and can provide clues into how human health might be affected by exposure to contaminated coastal water or seafood. "Dolphins and humans are both mammals,...

Scientists at NOAA's National Centers for Coastal Ocean Science and the Monterey Bay Aquarium Research Institute (MBARI) have successfully conducted the first remote detection of a harmful algal species and its toxin below the ocean's surface. The achievement was recently reported in the June issue of Oceanography.This achievement represents a significant milestone in NOAA's effort to monitor the type and toxicity of harmful algal blooms (HABs). HABs are considered to be increasing not only...

A dangerous nerve toxin emitted by algae off California's coast seems to be distressing creatures in the deep ocean. U.S. researchers believe this poisonous algae is a much larger danger that originally thought. According to a Reuters report, this algea, known as Pseudo-nitzschia, can create hazardous, large amounts of domoic acid. "It's a natural neurotoxin. It is produced by a diatom, which is a phytoplankton. As other animals eat this phytoplankton, like sardines or anchovies, this toxin...
