(Press-News.org) (San Diego, California – October 2, 2012) A tall ship owned and operated by Sea Education Association (SEA) will depart port tomorrow on a research expedition dedicated to examining the effects of plastic marine debris, including debris generated by the 2011 Japanese tsunami, in the ocean ecosystem.
During their 37-day cruise, the crew of the Woods Hole, Mass.-based sailing oceanographic research vessel Robert C. Seamans will explore a region between San Diego and Honolulu, popularly dubbed the "Great Pacific Garbage Patch", where high concentrations of plastic debris accumulate. Floating debris washed to sea by the March 2011 tsunami in Japan will also be drifting in the area, based on predictions from computer models and recent observations.
Updates on scientific findings and notable events will be provided by journalist Jonathan Waterman for National Geographic at http://newswatch.nationalgeographic.com/ as part of the Society's "Ocean Views" news, and daily on the expedition's website at http://www.sea.edu/plastics, including video footage and slideshows of the region of the North Pacific where SEA scientists expect to find plastic and other floating debris. In addition to measuring plastic debris, scientists onboard the expedition will be studying the communities of organisms living on floating plastic, from microorganisms to larger animals
such as barnacles and crabs, to determine whether or not this debris is a vector for invasive or pathogenic species.
"This expedition will be one of the first to unravel the impact that plastic pollution is having on our ocean's ecosystem. SEA has over 25 years of experience sampling marine debris and, using this knowledge, we will further investigate the health of our marine ecosystem," said Emelia DeForce, the expedition's chief scientist. "Those onboard will have a productive and eye-opening experience with long lasting effects. We will extend this experience to the public at large through our outreach program that will take place during and after the expedition, with the goal to raise awareness of the impact that this long-lived pollutant is having in our oceans."
This expedition, which will follow a 2500-nautical mile cruise track extending more than 1,500 nautical miles west of San Diego, expands upon SEA's 25-year history of measuring plastics, tar, and other marine debris in the Atlantic and Pacific Oceans. It is funded by Sea Education Association, with funding from the Henry L. and Grace Doherty Foundation in support of the web-based and educational outreach programs. Additional support provided by Patagonia and Elemental Herbs.
The SSV Robert C. Seamans is a 134-foot brigantine-rigged sailing oceanographic research vessel. The 38-person crew includes graduate students, educators, an environmental policy analyst, medical professionals, writers, a business professional, scientists, and professional mariners, most of whom are alumni of SEA's core academic program, SEA Semester.

RI Hospital: Differences in diagnosis, treatment of nonepileptic seizures in US, Chile
2012-10-02
PROVIDENCE, R.I. – Epileptic and psychogenic nonepileptic seizures (PNES) may look similar, but actually have different causes and treatments. Up to 20 percent of patients diagnosed with epilepsy actually have PNES, which are not treated by antiepileptic drugs (AEDs). According to a new study by Rhode Island Hospital researcher W. Curt LaFrance Jr., M.D., M.P.H., director of neuropsychiatry and behavioral neurology, increasing access to video electroencephalography (video-EEG) may aid in distinguishing between epilepsy and PNES. The study is published online in advance ...
Gene responsible for many spontaneous breast cancers identified
2012-10-02
BETHESDA, MD – October 2, 2012 -- Cancerous tumors contain hundreds of mutations, and finding these mutations that result in uncontrollable cell growth is like finding the proverbial needle in a haystack. As difficult as this task is, it's exactly what a team of scientists from Cornell University, the University of North Carolina, and Memorial Sloan-Kettering Cancer Center in New York have done for one type of breast cancer. In a report appearing in the journal GENETICS, researchers show that mutations in a gene called NF1 are prevalent in more than one-fourth of all noninheritable ...
Amazonian tribal warfare sheds light on modern violence, says MU anthropologist
2012-10-02
In the tribal societies of the Amazon forest, violent conflict accounted for 30 percent of all deaths before contact with Europeans, according to a recent study by University of Missouri anthropologist Robert Walker. Understanding the reasons behind those altercations in the Amazon sheds light on the instinctual motivations that continue to drive human groups to violence, as well as the ways culture influences the intensity and frequency of violence.
"The same reasons - revenge, honor, territory and jealousy over women - that fueled deadly conflicts in the Amazon continue ...
Manatees reflect quality of health in marine ecosystems, longterm study finds
2012-10-02
FAIRFAX, Va., October 1, 2012—A longterm study conducted by researchers at George Mason University may be a benchmark in determining health threats to marine mammals.
Over ten years of research in Belize was conducted studying the behavioral ecology, life history and health of manatees in an area relatively undisturbed by humankind.
"Manatees are the proverbial 'canaries in the mineshaft,' as they serve as indicators of their environment and may reflect the overall health of marine ecosystems," says Alonso Aguirre, executive director of the Smithsonian-Mason School ...
Adult stem cells change their epigenome to generate new organs
2012-10-02
The team led by Manel Esteller, director of the Cancer Epigenetics and Biology Program in the Bellvitge Biomedical Research Institute (IDIBELL), Professor of Genetics at the University of Barcelona and ICREA researcher, has identified epigenetic changes that occur in adult stem cells to generate different body tissues. The finding is published this week in The American Journal of Pathology.
The genome of every single cell in the human body is the same, regardless of their appearance and function. Therefore the activity of the tissues and organs and its disorders in complex ...
Hopkins study suggests treatments for 'wet' AMD keep elderly drivers behind the wheel
2012-10-02
The advanced neovascular, or "wet," form of age-related macular degeneration (AMD), left untreated, is the most common cause of vision loss among the elderly and a leading reason for their loss of driving privileges. But results of a new study, published in the online version of the journal Ophthalmology, suggest that monthly injections of ranibizumab improve eye chart test results required for a driver's license, build driver confidence and keep those with AMD driving longer.
The wet form of AMD is marked by the abnormal scarring and leaking of new blood vessels in ...
New findings on the workings of the inner ear
2012-10-02
The sensory cells of the inner ear have tiny hairs called stereocilia that play a critical part in hearing. It has long been known that these stereocilia move sideways back and forth in a wave-like motion when stimulated by a sound wave. After having designed a microscope to observe these movements, a research team at Karolinska Institutet in Sweden has discovered that the hairs not only move sideways but also change in length.
The discovery, which was made in collaboration with scientists at Baylor College of Medicine in Texas, USA provides new fundamental knowledge ...
New research measures the cost of getting cleaner air
2012-10-02
Extensive environmental regulations have brought cleaner air and health improvements to the United States, but they also have increased the cost of manufacturing and reduced industrial productivity, according to a study by economists at the University of Chicago and MIT.
Some economists have suggested that the regulations encouraged companies to become more efficient, thus reducing costs at upgraded plants. But in a paper published by the National Bureau of Economic Research, three economists contend that the regulations led to a 4.8 percent decline in productivity and ...
Study: An apple a day lowers level of blood chemical linked to hardening of the arteries
2012-10-02
COLUMBUS, Ohio – Eating an apple a day might in fact help keep the cardiologist away, new research suggests.
In a study of healthy, middle-aged adults, consumption of one apple a day for four weeks lowered by 40 percent blood levels of a substance linked to hardening of the arteries.
Taking capsules containing polyphenols, a type of antioxidant found in apples, had a similar, but not as large, effect.
The study, funded by an apple industry group, found that the apples lowered blood levels of oxidized LDL -- low-density lipoprotein, the "bad" cholesterol. When LDL ...
Among voters lacking strong party preferences, Obama faces 20% handicap due to race bias
2012-10-02
An online study of eligible voters around the country revealed that the preference for whites over blacks is the strongest in the least politically-partisan voters. Among these voters, race biases against Barack Obama could produce as much as a 20 percent gap in the popular vote in a contest that would otherwise be equal.
"Although they may not determine the election outcome, race biases are having a strong anti-Obama effect among the least politically partisan voters," said Anthony Greenwald, a University of Washington psychology professor who conducted the survey. "If ...
