(Press-News.org) Parkinson disease, a neurodegenerative disorder in which both genetic and environmental factors play important roles, has been associated with epigenetic changes (those molecular modifications that alter the behavior of genes without changing the DNA sequence). Because accurate diagnosis is not easy for this disease, scientists are continuously trying to identify early signs of the disease that enable treatment before major neurological damage occurs. In an article published in the October issue of Epigenetics, those epigenetic changes appear to be great candidates as early stage biomarkers for Parkinson Disease. Researchers from UCSD have now shown that a distinctive pattern of epigenetic modifications (in this case called DNA methylation) is observed in specific genes associated with the disease. Even more interesting, these changes could be easily analyzed in blood samples from patients, which appear to replicate the "epigenetic status" of brain tissue cells, potentially simplifying early diagnosis of the disease.

Deep sea ecosystem may take decades to recover from Deepwater Horizon spill
2013-09-25
The deep-sea soft-sediment ecosystem in the immediate area of the 2010's Deepwater Horizon well head blowout and subsequent oil spill in the Gulf of Mexico will likely take decades to recover from the spill's impacts, according to a scientific paper reported in the online scientific journal PLoS One.
The paper is the first to give comprehensive results of the spill's effect on deep-water communities at the base of the Gulf's food chain, in its soft-bottom muddy habitats, specifically looking at biological composition and chemicals at the same time at the same location.

Tweets reveal news readership patterns around the world
2013-09-25
Los Angeles, CA (September 25, 2013) For many international news followers, having a cup of coffee while reading the morning newspaper has turned into scrolling a Twitter feed to catch up on important news as it happens throughout the day. In a new article published in SAGE Open, researchers used data collected from Twitter to study readers' news preferences across the globe and discovered that different countries have stronger preference towards different types of articles – American and British readers are more drawn to opinion and world news, Spaniards to local and ...
Flame retardants in blood drop after state ban
2013-09-25
A class of flame retardants that has been linked to learning difficulties in children has rapidly declined in pregnant women’s blood since the chemicals were banned in California a decade ago, according to a study led by researchers at UC San Francisco.
Blood levels of polybrominated diphenyl ethers (PBDEs), tested in patients at the UCSF-affiliated San Francisco General Hospital and Trauma Center fell by two-thirds since they were last tested three years ago and found to be the highest levels reported among pregnant women anywhere in the world. The findings were ...
China's synthetic gas plants would be greenhouse giants
2013-09-25
DURHAM, N.C. -- Coal-powered synthetic natural gas plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke University researchers.
These environmental costs have been largely neglected in the drive to meet the nation's growing energy needs, the researchers say, and might lock China on an irreversible and unsustainable path for decades to come.
"Using coal to make natural gas may be good for China's energy security, ...
Unstable chromosomes linked to less favorable response to RT and surgery in prostate cancer patients
2013-09-25
Atlanta, September 25, 2013 -- Detailed evaluation of a prostate cancer tumor biopsy may predict treatment outcomes for image-guided radiation therapy (IGRT) or surgery for prostate cancer, according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 55th Annual Meeting. The study results indicate that patients who have abnormal levels of breaks at common fragile sites (CFSs), sites within the chromosomes that are sensitive to DNA damage, are more likely to have their cancer to return -- treatment failure. These CFS break abnormalities ...
Tiny camera records details of scene without losing sight of the big picture
2013-09-25
WASHINGTON, Sept. 25, 2013—To capture all the details of a crime scene, you might take many photos at close range. To get the whole scene at once, you could use a wide-angle or fisheye lens; but without an especially large lens you would be sacrificing the fine resolution that would help you catch that partial footprint you might otherwise have missed. Now a new type of miniature camera system promises to give users a big picture view without sacrificing high-resolution. Researchers from the University of California, San Diego will describe their novel device at The Optical ...
When the going gets tough, the materialistic go shopping
2013-09-25
EAST LANSING, Mich. -- Materialistic people experience more stress from traumatic events such as terrorist attacks and are more likely to spend compulsively as a result, according to an international study led by a Michigan State University business professor.
These possession-driven folks tend to have lower self-esteem than others, said Ayalla Ruvio, MSU assistant professor of marketing.
"When the going gets tough, the materialistic go shopping," said Ruvio. "And this compulsive and impulsive spending is likely to produce even greater stress and lower well-being. Essentially, ...
Wormlike hematite photoanode breaks the world-record for solar hydrogen production efficiency
2013-09-25
Ulsan, South Korea – A research team of Ulsan National Institute of Science and Technology (UNIST), South Korea, developed a "wormlike" hematite photoanode that can convert sunlight and water to clean hydrogen energy with a record-breaking high efficiency of 5.3%.
This research was published in Scientific Reports, a science journal published by the Nature Publishing Group. (Title: "Single-crystalline, wormlike hematite photoanodes for efficient solar water splitting") on 17 September 2013).
The previous record of solar hydrogen efficiency among stable oxide semiconductor ...
'Science in Society: Caring for our Futures in Turbulent Times'
2013-09-25
Issues of 'science in society' are not in themselves new, but this new report from the European Science Foundation, called "Science in Society: Caring for our Futures in Turbulent Times", is written at a critical time for science policy. Recent times have seen the world having to learn to deal with austerity, libel and new models of business. This all happens at a time when innovation is being promoted more vigorously than ever as a way out of crisis and as a foundation for future prosperity. As the report argues, increased governance of science and technology and the sense ...
Cocaine exposure in the womb: The brain structure is intact but development is off track
2013-09-25
Philadelphia, PA, September 25, 2013 – Prenatal cocaine exposure affects both behavior and brain. Animal studies have shown that exposure to cocaine during in utero development causes numerous disruptions in normal brain development and negatively affects behavior from birth and into adulthood.
For ethical reasons, similar studies in humans have been more limited but some research has shown that children exposed prenatally to cocaine have impairments in attention, control, stress, emotion regulation, and memory. Research also suggests that such children may be more predisposed ...
