New Rochelle, NY, January 8, 2015-- By defining a set of key metrics to evaluate the fuel systems available to drive autonomous and wearable soft robots, a team of engineers and chemists are able to compare the advantages and limitations of current technology options. They assess various types of pneumatic energy sources and their benefits for specific applications in an article published in Soft Robotics, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Soft Robotics website.

Michael Wehner and coauthors from Harvard University (Cambridge and Boston, MA), Oregon State University (Corvallis, OR), Carnegie Mellon University (Pittsburgh, PA), Robot G and I Research (Bedford, MA), Worcester Polytechnic Institute (Worcester, MA), and Cornell University (Ithaca, NY), characterize the most advanced pneumatic energy systems designed to power untethered and wearable soft robots based on their energy density and flow capacity, as well as noise, toxic byproducts, application-specific requirements, and the time and additional parts needed for development. The goal of the study, entitled "Pneumatic Energy Sources for Autonomous and Wearable Soft Robotics," is to provide a framework for configuring fuel systems in soft robotics.

"As soft pneumatic systems start to gain acceptance in robotic applications, it is vital that the advantages and limitations of different energy systems are fully explored. This paper provides comparisons and analysis that will useful for anyone designing such systems," says Editor-in-Chief Barry A. Trimmer, PhD, who directs the Neuromechanics and Biomimetic Devices Laboratory at Tufts University (Medford, MA).

New study from Harvard compares design of fuel systems for soft robots

GMO is an abbreviation for a genetically modified organism whose genome has been altered by the techniques of genetic engineering so that its DNA contains one or more genes not normally found there.

Eighty per cent of our food contains some sort of GMO that you buy at the grocery store, and proponents of the technology point out theres not one incidence of human health issue. The USDA, the FDA, the CDC, and the United Nations Food and Agricultural Organization have all concluded that the technology is safe, and agricultural producers maintain that this technology is an absolutely necessary tool for them to be able to feed a growing world population. Travis Miller is the Interim Associate Director for State Operations for the Texas A&M Agrilife Extension Service.

Id encourage people, I like to do a garden myself, and Id encourage people to grow a garden but you cant feed the 300 million people in the United States all with back yard gardens, plus the 50% or more of our crop that we send overseas to feed other people. And GMOs have provided the technology that has reduced the pesticide use, has reduced the insect damage to our crops, has improved the quality of our crops, so that we do have the, its one of the many technologies that were now using to get the kind of yields we have to have to continue to feed the world.

Genetically Modified Organism technology is invaluable to plant breeders. If you look at what crops used to look like when we first started cultivating crops, the dont even resemble what we have today. And that was through traditional breeding technology, pollen from one source and pollen from another source. Problems that have plagued agriculture for decades are being addressed.

Now GMO is another important tool that a plant breeder can put in his tool box and say, oh, well what about this plant disease that we have, well heres a gene that I can take from a spinach plant and put in in a grapefruit and solve a disease thats going to take the citrus industry out.

From the Ground Up - GMOs Necessary To Feed The World

Organic agriculture is the most expensive, expansive hoax perpetrated on consumers during the past half-century. An affront to the environment because its low yields arewasteful of water and farmland, organic agricultureconfers no advantages except for the feel-good factor for true believers. It only survives because of massive government subsidies and promotion, and black marketing that dishonestly disparages the competition .

My exposs of the many shortcomings and waning credibility of the organic agriculture industry have received a prodigious amountof attention. A 2012 Forbes column got more than a quarter million views. My most recent one on this subject, last month, attracted not only tens of thousands of readers but also a complaint from Jessica Shade, who bills herself as Director of Science Programs at The Organic Center. Thats something of an oxymoron, inasmuch as science holds little sway atthe advocacy organization she works for.

Shades preamble establishes her lack of credibility: U.S. Department of Agriculture (USDA) organic standards are based around the principles of sustainability and health. In addition, organic farming has many environmental advantages when compared to conventional farming.

None of that is true. Let me be clear about one thing, Secretary of Agriculture Dan Glickman said when organic certification was being considered, the organic label is a marketing tool. It is not a statement about food safety. Nor is organic a value judgment about nutrition or quality.

Organic standards are wholly arbitrary, and in any case, as a recent report in the Wall Street Journal described, they are not being enforced very effectively: An investigation by the newspaper of USDA inspection records since 2005 found that 38 of the 81 certifying agentsentities accredited by USDA to inspect and certify organic farms and suppliersfailed on at least one occasion to uphold basic Agriculture Department standards. More specifically, 40% of these 81 certifiers have been flagged by the USDA for conducting incomplete inspections; 16% of certifiers failed to cite organic farms potential use of banned pesticides and antibiotics; and 5% failed to prevent potential commingling of organic and nonorganic products.

In December 1997, when USDA tried to set standards for organic agricultural production, the original version was rejected by the organic enthusiasts, largely because itwould have permitted the use of organisms modified with modern genetic engineering techniquesquite sensibly, in the view of the scientific community. In the end, modern genetic engineering, which employs highly precise and predictable techniques, was prohibited, while genetic modification with older, far less precise, less predictable and less effective techniques got waved through.

The resulting standards, which are based on a sentimental back-to-Nature, technological progress is evil ethic, arbitrarily define which pesticides are acceptable, but allow deviations if based on need. Synthetic chemical pesticides are generally prohibitedalthough there is a lengthylist of exceptions listed in the Organic Foods Production Actwhile most natural ones are permitted. The application as fertilizer of pathogen-laden animal excreta to the foods we eat is not only allowed, but in organic dogma, virtually sacred.

Dont let anyone confuse you: Organic pesticides can be toxic.As evolutionary biologist Christie Wilcoxexplainedin a 2012Scientific Americanarticle (Are lower pesticide residues a good reason to buy organic?Probably not.): Organic pesticides pose the same health risks as non-organic ones.

The designation organic is itself asyntheticconstruct of activists and bureaucrats that makes little sense.Moreover, organic standards are based on sets of principles and techniques which have nothing to do with the ultimate quality or composition of the final products. For example, if prohibited chemical pesticides or pollen fromforbidden genetically engineered plants wafts onto and contaminates an organic field, guess what? The farmer gets a mulligan: He does not lose his organic certification.

New Rochelle, NY, January 6, 2015--Timothy Ray Brown, long known only as the "Berlin Patient" had HIV for 12 years before he became the first person in the world to be cured of the infection following a stem cell transplant in 2007. He recalls his many years of illness, a series of difficult decisions, and his long road to recovery in the first-person account, "I Am the Berlin Patient: A Personal Reflection," published in AIDS Research and Human Retroviruses, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is part of a special issue on HIV Cure Research and is available free on the AIDS Research and Human Retroviruses website.

Brown's Commentary describes the bold experiment of using a stem cell donor who was naturally resistant to HIV infection to treat the acute myeloid leukemia (AML) diagnosed 10 years after he became HIV-positive. The stem cell donor had a specific genetic mutation called CCR5 Delta 32 that can protect a person against HIV infection. The virus is not able to enter its target, the CD4 cells. After the stem cell transplant, Brown was able to stop all antiretroviral treatment and the HIV has not returned.

"This is the first time that we get to read this important story written by the man who lived it," says Thomas Hope, PhD, Editor-in-Chief of AIDS Research and Human Retroviruses and Professor of Cell and Molecular Biology at Northwestern University, Feinberg School of Medicine, Chicago, IL. "It is a unique opportunity to share in the human side of this transformative experience."

New Rochelle, NY, January 6, 2015-The shocking statistic that about one in five women will be the victim of sexual assault while in college is made even more so by the fact that most of those women will know their assailants. No one-size-fits-all approach to rape prevention will be effective, as some offenders are driven by hostility toward women, while others may objectify women and view forceful intercourse as part of expected male dominant behavior. These different motivations and views on rape, and how they can be used to deliver rape prevention measures and successful intervention strategies are explored in an article in Violence and Gender, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Violence and Gender website until February 6, 2015.

In the article "Denying Rape but Endorsing Forceful Intercourse: Exploring Differences Among Responders," Sara Edwards, PhD, and Kathryn Bradshaw, University of North Dakota, Grand Forks, and Verlin Hinsz, PhD, North Dakota State University, Fargo, separated male participants into three groups based on how they scored on measurements of hypermasculinity, hostility toward women, and callous sexual attitudes. The authors reported associations between these groupings and whether the men denied any intention to rape or use force to obtain intercourse, self-reported intentions to rape, or indicated a distinction between sexually coercive behavior and rape and expressed intentions to use of force to obtain intercourse but denied rape.

"These authors describe the numbers as staggering, and we know it is one of the most concerning crimes in the country today," says Violence and Gender Editor-in-Chief Mary Ellen O'Toole, PhD, Forensic Behavioral Consultant and Senior FBI Profiler/Criminal Investigative Analyst (ret.). "Sexual assault on college campuses is the pink elephant in the room. It is a crime that is underreported and misunderstood. In this article, researchers look at how callous sexual attitudes of some males who do not have feelings of hostility toward women can still engage in forced intercourse with a victim, and consider their behavior as an achievement rather than rape. The implications for these findings are extremely significant for education programs about sexual aggression and rape prevention and the development of a more accurate identification of subtypes of offenders based on their motivation, cognition, and personality traits."
