(McLean Hospital) An extract of the Chinese herb kudzu dramatically reduces drinking and may be useful in the treatment of alcoholism and curbing binge drinking, according to a new study by McLean Hospital and Harvard Medical School researchers.
“Our study is further evidence that components found in kudzu root can reduce alcohol consumption and do so without adverse side effects,” said David Penetar, PhD, of the Behavioral Psychopharmacology Research Laboratory at McLean Hospital, and the lead author of the study. “Further research is needed, but this botanical medication may lead to additional methods to treat alcohol abuse and dependence.”
By Sarah Kliff (Washington Post) California’s strict school nutrition standards — soda bans, low calorie foods in cafeterias and limits on fat content — appear to have had a significant impact on what teens there eat.
A study of about 700 teenagers, published this week in the Archives of Pediatric Medicine, found California teens to be consuming 158 fewer, daily calories than comparable high school students in other states. Keep in mind, that counts all the food eaten outside of school, indicating that California teens aren’t loading up on junk food after heading home.

By Dave Smith (International Business Times) A promising new birth control treatment — for men, not women — looks to be the future of contraception. It’s safe, relatively uninvasive, 100 percent effective, and completely reversible. Developed by Prof. Sujoy K. Guha of the Indian Institute of Technology, the procedure called “Reversible Inhibition of Sperm Under Guidance,” or RISUG, is currently in advanced clinical trials in India. Researchers hope to get Vasalgel (or “RISUG” in the Indian trials) on the market as a common alternative to vasectomy as early as 2015.
In this new procedure, a doctor would inject a polymer gel called “Vasalgel” directly into the vas deferens instead of cutting it, which coats the walls of the duct and kills sperm as they go by. Should the man want to reverse the treatment for any reason at all, the procedure can be reversed simply by flushing out the Vasalgel with another injection of DMSO, a compound that is used in the medical treatment of many conditions and that is bioacceptable in the small quantities necessary.
(EurekaNet) According to a recent study headed by scientists from the University of Las Palmas de Gran Canaria and the University of Granada, eating commercial baked goods (fairy cakes, croissants, doughnuts, etc.) and fast food (hamburgers, hotdogs and pizza) is linked to depression.
Published in the Public Health Nutrition journal, the results reveal that consumers of fast food, compared to those who eat little or none, are 51% more likely to develop depression.
Furthermore, a dose-response relationship was observed. In other words this means that “the more fast food you consume, the greater the risk of depression,” explains Almudena Sánchez-Villegas, lead author of the study, to SINC.
The study demonstrates that those participants who eat the most fast food and commercial baked goods are more likely to be single, less active and have poor dietary habits, which include eating less fruit, nuts, fish, vegetables and olive oil. Smoking and working more than 45 hours per week are other prevalent characteristics of this group.
By Krista Conger (Inside Standford Medicine) Human tumors transplanted into laboratory mice disappeared or shrank when scientists treated the animals with a single antibody, according to a new study from the Stanford University School of Medicine. The antibody works by masking a protein flag on cancer cells that protects them from macrophages and other cells in the immune system. The scientists achieved the findings with human breast, ovarian, colon, bladder, brain, liver and prostate cancer samples.
It is the first antibody treatment shown to be broadly effective against a variety of human solid tumors, and the dramatic response — including some overt cures in the laboratory animals — has the investigators eager to begin phase-1 and –2 human clinical trials within the next two years.
“Blocking this ‘don’t-eat-me’ signal inhibits the growth in mice of nearly every human cancer we tested, with minimal toxicity,” said professor of pathology Irving Weissman, MD, who directs Stanford’s Institute of Stem Cell Biology and Regenerative Medicine and the Ludwig Center for Cancer Stem Cell Research and Medicine at Stanford. “This shows conclusively that this protein, CD47, is a legitimate and promising target for human cancer therapy.”
The antibody treatment also significantly inhibited the ability of the tumors to metastasize throughout the animals’ bodies.
By Sybille Hildebrandt ( ScienceNordic) Antioxidants, dietary supplements, vitamin pills – many people take them every day in the hope that they are good for their health.
But a new Danish study of all relevant trials carried out around the world shows that taking antioxidants in the form of vitamin A, E and beta-carotene is a risky business for us.
These antioxidants increase mortality – the risk of sudden death is higher for people who take these dietary supplements than for those who do not.
The results of this study have just been published in the scientific journal Cochrane Library.

By Walter Brash (Moronia) The history of energy exploration, mining, and delivery is best understood in a range from benevolent exploitation to worker and public oppression. A company comes into an area, leases land in rural and agricultural areas for mineral rights, increases employment, usually in a depressed economy, strips the land of its resources, creates health problems for its workers and those in the immediate area, and then leaves.
It makes no difference if it’s timber, oil, or coal. In the 1970s and 1980s, the nuclear energy industry promised well-paying jobs, clean energy, and a safe health and work environment. Chernobyl, Three Mile Island, Fukushima Daiichi, and thousands of violations issued by the Nuclear Regulatory Agency, have shown that even with strict operating guidelines, nuclear energy isn’t as clean and safe as claimed. Like all other energy industries, nuclear power isn’t infinite. Most plants have a 40–50 year life cycle. After that, the plant becomes so radioactive hot that it must be sealed.
In the early 21st century, the natural gas industry follows the model of the other energy corporations, and uses the same rhetoric. James M. Taylor, senior fellow at the Heartland Institute, claims on the Institute’s website, “The newfound abundance of domestic gas reserves promises unprecedented energy prosperity and security.”
The energy policy during the eight years of the George W. Bush–Dick Cheney administration was to give favored status to the industry, often at the expense of the environment. In addition to negating Bill Clinton’s strong support for the Kyoto Protocol, signed by 191 countries, to reduce greenhouse-gas emissions, former oil company executives Bush and Cheney pushed to open significant federal land, including the 19 million acre Arctic National Wildlife Refuge (ANWR), to drilling that would disrupt the ecological balance in one of the nation’s most pristine areas.
A study by the Environmental Protection Agency (EPA), published in 2004 concluded that fracking was of little or no risk to human health. However, Wes Wilson, a 30-year EPA environmental engineer, in a letter to members of Congress and the EPA inspector general, called that study “scientifically unsound,” and questioned the bias of the panel, noting that five of the seven members had significant ties to the industry. “EPA’s failure to regulate [fracking] appears to be improper under the Safe Water Drinking Act and may result in danger to public health and safety.”
By Walter Brasch (Moronia)– The natural gas industry defends hydraulic fracturing, better known as fracking, as safe and efficient. Thomas J. Pyle, president of the Institute for Energy Research, a pro-industry non-profit organization, claims fracking has been “a widely deployed as safe extraction technique,” dating back to 1949. What he doesn’t say is that until recently energy companies had used low-pressure methods to extract natural gas from fields closer to the surface than the current high-pressure technology that extracts more gas, but uses significantly more water, chemicals, and elements.
The industry claims well drilling in the Marcellus Shale will bring several hundred thousand jobs, and has minimal health and environmental risk. President Barack Obama in his January 2012 State of the Union, said he believes the development of natural gas as an energy source to replace fossil fuels could generate 600,000 jobs.
However, research studies by economists Dr. Jannette M. Barth, Dr. Deborah Rogers, and others debunk the idea of significant job creation.
Barry Russell, president of the Independent Petroleum Association of America, says “no evidence directly connects injection of fracking fluid into shale with aquifer contamination.” Fracking “has never been found to contaminate a water well,” says Christine Cronkright, communications director for the Pennsylvania Department of Health.
Research studies and numerous incidents of water contamination prove otherwise.
In late 2010, equipment failure may have led to toxic levels of chemicals in the well water of at least a dozen families in Conoquenessing Twp. in Butler County. Township officials and Rex Energy, although acknowledging that two of the drilling wells had problems with the casings, claimed there were pollutants in the drinking water before Rex moved into the area. John Fair disagrees. “Everybody had good water a year ago,” Fair told environmental writer and activist Iris Marie Bloom in February 2012. Bloom says residents told her the color of water changed (to red, orange, and gray) after Rex began drilling. Among chemicals detected in the well water, in addition to methane gas, were ammonia, arsenic, chloromethane, iron, manganese, t-butyl alcohol, and toluene. While not acknowledging that its actions could have caused the pollution, Rex did provide fresh water to the residents, but then stopped doing so on Feb. 29, 2012, after the Pennsylvania Department of Environmental Protection (DEP) said the well water was safe. The residents vigorously disagreed and staged protests against Rex; environmental activists and other residents trucked in portable water jugs to help the affected families. Jospeh P. McMurry of the Marcellus Outreach Butler blog (MOB) declared that residents’ “lives have been severely disrupted and their health has been severely impacted. To unceremoniously ‘close the book’ on investigations into their troubles when so many indicators point to the culpability of the gas industry for the disruption of their lives is unconscionable.”
(Medical Express) Findings from a first-of-its-kind study by Indiana University researchers confirm anecdotal evidence that exercise — absent sex or fantasies — can lead to female orgasm.

While the findings are new, reports of this phenomenon, sometimes called “coregasm” because of its association with exercises for core abdominal muscles, have circulated in the media for years, said Debby Herbenick, co-director of the Center for Sexual Health Promotion in IU’s School of Health, Physical Education and Recreation. In addition to being a researcher, Herbenick is a widely read advice columnist and book author.
“The most common exercises associated with exercise-induced orgasm were abdominal exercises, climbing poles or ropes, biking/spinning and weight lifting,” Herbenick said. “These data are interesting because they suggest that orgasm is not necessarily a sexual event, and they may also teach us more about the bodily processes underlying women’s experiences of orgasm.”
The findings are published in a special issue of Sexual and Relationship Therapy, a leading peer-reviewed journal in the area of sex therapy and sexual health. Co-author is J. Dennis Fortenberry, M.D., professor at the IU School of Medicine and Center for Sexual Health Promotion affiliate.
The results are based on surveys administered online to 124 women who reported experiencing exercise-induced orgasms (EIO) and 246 women who experienced exercise-induced sexual pleasure (EISP). The women ranged in age from 18 to 63. Most were in a relationship or married, and about 69 percent identified themselves as heterosexual.
