When the University of Iowa College of Public Health and the Institute for Agriculture and Trade Policy tested 395 samples from 36 stores in Iowa, Minnesota, and New Jersey, they found 7 percent carried MRSA.

“This study shows that the meat we buy in our grocery stores has a higher prevalence of staph than we originally thought,” says lead study author Tara Smith, Ph.D., interim director of the UI Center for Emerging and Infectious Diseases and assistant professor of epidemiology. “With this knowledge, we can start to recommend safer ways to handle raw meat products to make it safer for the consumer.”

The study also noted that pork raised with antibiotics or antibiotic growth promotants were not significantly different in MRSA contamination from antibiotic-free pork products.

“We were surprised to see no significant difference in antibiotic-free and conventionally produced pork,” Smith says. “Though it’s possible that this finding has more to do with the handling of the raw meat at the plant than the way the animals were raised, it’s certainly worth exploring further.”

Researchers wanted to know why we are not getting smarter than we are given the adaptive evolutionary process. Their findings suggested that for every gain in cognitive functions, there is a price to pay elsewhere.

For instance, among individuals with enhanced cognitive abilities – such as savants, people with photographic memories, and even genetically segregated populations of individuals with above average IQ – these individuals often suffer from related disorders, such as autism, debilitating synaesthesia, and neural disorders linked with enhanced brain growth.

Also included in the research was the use of drugs like Ritalin, which only help people with lower attention spans, whereas people who don’t have trouble focusing can actually perform worse when they take attention-enhancing drugs.

University of Warwick psychology researcher Thomas Hills said: “If you enhance your ability to focus too much, and end up over-focusing on specific details, like the driver trying to hide in your blind spot, then you may fail to see another driver suddenly veering into your lane from the other direction.”

The research, entitled ‘Why Aren’t We Smarter Already: Evolutionary Trade-Offs and Cognitive Enhancements,’ is published in Current Directions in Psychological Science, a journal of the Association for Psychological Science.

Bt corn, one of the nation’s most widely produced crops, is thought to be losing its natural resistance to the western corn rootworm, a pest that feeds on the roots of corn and could potentially wreak economic havoc if it continues to spread.

Currently the infestations remain isolated, but concerns have been growing ever since Bt corn infestations have been discovered in four Midwestern states, a sign that the repeated planting of the corn strain – instead of being rotated with other crops – is enabling the insects’ resistance to the crop’s pest-fighting powers. Many farmers are foregoing rotation in order to cash in on the high corn prices.

Bt corn was introduced to farmers in 2003 and allowed growers to bring in bountiful harvests using fewer chemicals because the corn naturally produces a toxin that poisons the common pest.

Because of the corn farmers’ current – and most likely ongoing – practices, some scientists fear it could already be too late to prevent the rise of resistance. In addition, they’re also concerned about the problem becoming more widespread due to the rootworm larvae growing into adult beetles that can fly and migrate into new areas.

If rootworms do become resistant to Bt corn, it “could become the most economically damaging example of insect resistance to a genetically modified crop in the U.S.,” said Bruce Tabashnik, an entomologist at the University of Arizona. “It’s a pest of great economic significance — a billion-dollar pest.”

Brain shrinkage is typical of Alzheimer’s disease. Previous studies hinted at the role that nutrition may play in staving off the disease, but this study, the first of its kind, measured 30 different blood nutrient levels, reflecting a much wider range of nutrients, and adds specificity to the findings.

“This approach clearly shows the biological and neurological activity that’s associated with actual nutrient levels, both good and bad,” said Maret Traber, a principal investigator with the Linus Pauling Institute and co-author on the study.

“The vitamins and nutrients you get from eating a wide range of fruits, vegetables and fish can be measured in blood biomarkers,” Traber said. “I’m a firm believer these nutrients have strong potential to protect your brain and make it work better.”

The study group included elderly people with an average age of 87 with no special risk factors for memory or mental acuity.

The most favorable cognitive outcomes and brain size measurements were associated with two dietary patterns – high levels of marine fatty acids, and high levels of vitamins B, C, D and E. Trans-fatty foods were associated with the worst cognitive performance.

The dead zone area in the Gulf of Mexico is forecasted to grow to the size of New Hampshire, approximately 8,500 to 9,421 square miles, due to major flooding on the Mississippi river this spring. If this happens, it will be the largest recorded dead (hypoxic) zone in the Gulf of Mexico since it was first measured in 1985, according to NOAA scientists.

Hypoxic areas in seas and oceans is caused by excessive nutrient pollution, usually from agriculture run-off. This results in too little oxygen to support most marine life in bottom and near-bottom water. These dead zone areas, such as the Gulf one growing just off the coast of Louisiana and Texas,  are a threat to commercial and recreational Gulf fisheries.

“This ecological forecast is a good example of NOAA applied science,” said Jane Lubchenco, Ph.D., under secretary of commerce for oceans and atmosphere and NOAA administrator. “While there is some uncertainty regarding the size, position and timing of this year’s hypoxic zone in the Gulf, the forecast models are in overall agreement that hypoxia will be larger than we have typically seen in recent years.”

Researchers should know more about its size following a NOAA-supported monitoring survey led by the Louisiana Universities Marine Consortium between July 25 and August 6.

NOAA has been funding investigations and forecast development for the dead zone in the Gulf of Mexico since 1990 and currently oversees the two national hypoxia programs authorized by the Harmful Algal Bloom and Hypoxia Research and Control Act.

And other statistics related to the issue are of grave concern:

• The majority of patients under age 65 years receive at least one prescription drug annually.
• Four million prescriptions for long-acting painkillers are written every year; painkillers are the most commonly prescribed drugs in America.
• In 2007 there were 11,500 deaths related to painkillers; experts say the drugs do not always deliver substantial pain relief, and carry a high risk of addiction, side effects, and death.

Gordon D. Schiff, M.D., from Harvard Medical School, Boston, with colleagues in the medical and pharmacy divisions of the University of Illinois at Chicago, outlines a series of steps in their published report that appeared Archives of Internal Medicine,one of the JAMA/Archives journals, that can be taken to rein in prescription writing. “Although others have used labels such as healthy skepticism, more judicious, rational, careful, or cautious prescribing,” they write, “we believe that the term conservative prescribing conveys an approach that goes beyond the oft-repeated physician’s mantra, ‘first, do no harm.’”

Dr. Schiff’s recommendations include:

• Determine if other interventions besides prescription drugs would be more helpful;
• Use discernment when prescribing to determine the best choices available and avoid using multiple prescriptions;
• Be more vigilant about adverse side effects, including patients’ potential drug reactions, instructing them about the warning signs, and being more discerning about choosing prescriptions that make a patient more prone to withdrawal symptoms or relapse;
• Be judicious about claims being made about any new drug’s benefits, perhaps waiting until it has a proven track record, and ensuring it targets the core issue;
• Collaborate with patients on a shared agenda for more effective treatment, such as encouraging them to use skepticism about promises made in advertisements and re-think demanding those drugs, and encouraging them to be more compliant with suggested approaches to treatment;
• Consider foremost the long-term effects of prescription drug treatments and consider different therapies that are less likely to cause chronic health issues.

The experts recommend taking greater care when deciding to prescribe a drug, especially one that is new or not well understood. “While clinicians must always weigh the benefits of conservative prescribing against the risks of withholding potentially needed medications, at the very least we should seek to shift the burden of proof toward demanding a higher standard of evidence of benefit before exposing patients to the risks of drugs.”

In a study by the University of Bordeaux of 7,625 people aged 65 and older, those who regularly used olive for cooking and as a dressing had a 41 percent lower risk of stroke compared with those who never consumed olive oil.

“Our research suggests that a new set of dietary recommendations should be issued to prevent stroke in people 65 and older,” said study author Cécilia Samieri, PhD, with the University of Bordeaux and the National Institute of Health and Medical Research (INSERM) in Bordeaux, France. “Stroke is so common in older people and olive oil would be an inexpensive and easy way to help prevent it.”

Olive oil is associated with other proven health benefits as well, such as protective effects against diabetes, high blood pressure, high cholesterol, and diabetes.

Based on core samples from 55.9 million years ago, when the earth last experienced a rapid period of global warming, our current rate of carbon release is nearly 10 times as fast. According to geologists, rate matters and this current rapid change may not allow sufficient time for the biological environment to adjust.

The past warming period, known as the Paleocene-Eocene Thermal Maximum (PETM), experienced a rapid increase in global temperatures over a time span of 20,000 years. Based on models developed at Penn State University, the outcome was a warming of from 9 to 16 degrees Fahrenheit and an acidification event in the oceans.

“Rather than the 20,000 years of the PETM which is long enough for ecological systems to adapt, carbon is now being released into the atmosphere at a rate 10 times faster,” said Lee R. Kump, professor of geosciences at Penn State. “It is possible that this is faster than ecosystems can adapt.”

The hypnosis was performed on breast cancer and thyroid patients. ”In all of these procedures local anaesthesia is feasible but not, on its own, sufficient to ensure patient comfort,” says Professor Roelants from the Department of Anaesthesiology at the Cliniques Universitaires St. Luc, UCL, Brussels, Belgium.

“In addition to reducing drug use and hospital stay time, being able to avoid general anaesthesia in breast cancer surgery is important because we know that local anaesthesia can block the body’s stress response to surgery and could therefore reduce the possible spread of metastases,” said Professor Roelants.

The anesthesiologists use eye fixation, progressive muscle relaxation, or the retrieval of a pleasant memory to focus a patient’s attention on one particular point, enabling a modified state of consciousness, with a different perception of the world.

“There is still a lot of debate around the exact mechanism that allows hypnosis to reduce pain perception,” said Professor Roelants,” but what it absolutely clear is that it does so. The result is that one third of thyroidectomies and a quarter of all breast cancer surgery carried out at the UCL hospital are performed under local anaesthetic with the patient under hypnosis.”

The anesthesiologists have confirmed that, regardless of sex or age, and if the patient is motivated, ready to co-operate, and trusts the doctors, hypnosis will work. It can also be applied to surgical patients who undergo carotid artery surgery, inguinal hernia, knee arthroscopy, gynaecological surgery, ophthalmology, ear nose and throat, plastic surgery and egg retrieval for fertility treatment.

The research findings were presented June 12, 2011 at the European Anaesthesiology Congress in Amsterdam.

“We know this strategy works, and it works in sports,” says sports psychologist Antonis Hatzigeorgiadis. But Hatzigeorgiadis and fellow researchers wanted to know more – specifically, what makes it work better, and in what circumstances.

Researchers at the Department of Physical Education and Sport Sciences at the University of Thessaly found that different self-talk cues work differently in different situations.

For tasks requiring fine skills or for improving technique “instructional self-talk,” such as a technical instruction (“elbow-up” which Hatzigeorgiadis coaches beginner freestyle swimmers to say) is more effective than “motivational self-talk” (e.g., “give it all”), which seems to be more effective in tasks requiring strength or endurance, boosting confidence and psyching-up for competition.

Also, probably because it improves concentration, self-talk has a greater effect on tasks involving fine skills (such as sinking a golf ball) rather than gross skills (e.g., cycling). The researchers also found that self-talk is more effective for learning new tasks rather than well-learned tasks, because it is easier to improve at the early steps of learning.

The main goals behind self-talk—like other techniques such as visualization to “rehearse” a performance or meditation to improve focus and relaxation—are twofold, says Hatzigeorgiadis: “to enhance your potential; and to perform during competition in terms of your ability and not less.”
