Diet Reduces Heart Attacks
A large study offers the strongest evidence yet that a diet the government recommends for lowering blood pressure can save people from heart attack and stroke.
According to AP, researchers followed more than 88,000 healthy women for almost 25 years. They examined their food choices and looked at how many had heart attacks and strokes.
Those who fared best had eating habits similar to those recommended by the government to stop high blood pressure.
The plan, called the DASH diet, favors fruits, vegetables, whole grains, low-fat milk and plant-based protein over meat.
Women with those eating habits were 24 percent less likely to have a heart attack and 18 percent less likely to have a stroke than women with more typical American diets.
Those are meaningful reductions since these diseases are so common. About two in five US women at age 50 will eventually develop cardiovascular disease, which includes heart attacks and strokes. Women in the study were in their mid-30s to late 50s when the research began in 1980.
Previous research has shown this kind of diet can help prevent high blood pressure and cholesterol, which both can lead to heart attacks.

Ethnic Clothes Linked to Mental Health
Teenage girls from some minority communities who stick to their family customs have better mental health, researchers say.
Queen Mary University of London found Bangladeshi girls who chose traditional rather than western dress had fewer behavioral and emotional problems, BBC said.
The team said close-knit families and communities could help protect them.
Pressure to integrate fully could be stressful, the Journal of Epidemiology and Community Health reported.
Adolescents are particularly vulnerable to mental health problems, and the researchers said that identity, often bound up in friendship choices or clothing, played a role.
They questioned a total of 1,000 white British and Bangladeshi 11 to 14-year-olds about their culture, social life and health, including questions designed to reveal any emotional or mental problems.
Bangladeshi pupils who wore traditional clothing were significantly less likely to have mental health problems than those whose style of dress was a mix of traditional and white British styles.

Too Many Choices Not Very Good
Each day, we are bombarded with options--at the local coffee shop, at work, in stores or on the TV at home. Having choices is typically thought of as a good thing.
Maybe not, say researchers who found we are more fatigued and less productive when faced with a plethora of choices, Physorg reported.
Researchers from several universities have determined that even though humans’ ability to weigh choices is remarkably advantageous, it can also come with some serious liabilities. People faced with numerous choices, whether good or bad, find it difficult to stay focused enough to complete projects, handle daily tasks or even take their medicine.
Researchers conducted seven experiments involving 328 participants and 58 consumers at a shopping mall. In the laboratory experiments, some participants were asked to make choices about consumer products, college courses or class materials. Other participants did not have to make decisions but simply had to consider the options in front of them.
The scientists then asked each group to participate in one of two unpleasant tasks. Some were told to finish a healthy but ill-tasting drink (akin to taking one’s medicine).
Other participants were told to put their hands in ice water. The tasks were designed to test how the previous act of choosing, or not choosing, affected peoples’ ability to stay on task and maintain behaviors aimed at reaching a goal.
Researchers found that participants who earlier had made choices had more trouble staying focused and finishing the disagreeable but goal-focused tasks compared to participants who initially did not have to make choices.

Scientists Testing
Anti-Snoring Pill
A pill that could prevent heavy snoring, bringing relief to thousands of sufferers and their spouses, is being developed by scientists.
Around 80,000 people in Britain suffer from obstructive sleep apnoea (OSA), which affects their breathing and can interrupt their sleep, leaving them tired and irritable, Telegraph reported.
But researchers believe they may be closer to finding a treatment for the condition after the success of an initial study.
The trial involved 39 patients with the condition taking either a placebo or varying doses of the drugs daily for 28 days.
Those who took high doses of the pill enjoyed a “statistically significant reduction“ in OSA of around 40 percent, compared to patients who took the placebo.
Three of the ten people in the high-dose group saw their symptoms reduced by 50 percent and were considered to have responded completely.
Waterproof Edible Packing
Edible films have been increasingly used in recent years to protect food items from oxygen and also as a more sustainable alternative to traditional packaging.
However, according to NewScientist, the most commonly used material for an edible film, a polysaccharide such as starch, has one significant disadvantage: it is broken down by water. That means that so far edible packaging is much less useful than more traditional and less sustainable materials like plastics.
Now Jung Han at the Department of Food Science at the University of Manitoba in Canada says that adding beeswax to starch from peas produces an edible material that can be spread into thin films but is water resistant too. Perhaps plastic packaging’s days are numbered--although Han doesn’t describe how a pea starch and beeswax mix tastes.
Statins May Reduce Blood Pressure
Anti-cholesterol drugs known as statins, the world’s top-selling prescription drugs, may modestly help reduce blood pressure and bring additional cardiovascular benefits, said a medical study.
Physicians at University of California, San Diego conducted a double-blind trial with 973 people who did not have diabetes or cardiovascular disease, AFP said.
The group was divided in three equal parts, with one given 20 milligrams of simvastatin, another 40 milligrams of pravastatin and the third placebo, every day for six months, said Beatrice Golomb, chief author of the study published by the Archives of Internal Medicine.
Doctors took the blood pressure of the study participants at the beginning of the clinical trial, at one and six months into the treatment and two months after the trial ended.
“Blood pressure reductions ranged from 2.4 to 2.8 millimeters of mercury for both systolic blood pressure (normal is 120 millimeters) and diastolic blood pressure (normal is 80 millimeters) with both simvastatin and pravastatin,“ the authors said.
There was no practical difference in blood pressure among the group given placebo, they added.
The effect of statins on blood pressure was not evident at one month of treatment, was significant at six months of treatment and dissipated two months after treatment ended,“ they said.
“This study adds to our understanding of the effects of statins, currently the best-selling prescription drugs in the world,“ the authors said.
Fan-Assisted Trucks
Travel at 70 mph on a motorway, and approximately 65 percent of the fuel you burn goes to overcoming aerodynamic drag. So even a slight reduction in drag will significantly improve fuel consumption. This is a particular problem for lorries and buses.
Kambiz Salari at the Lawrence Livermore National Laboratory in California and colleagues say that much of the drag from a “bluff body“ such as bus or truck comes from the air vortices generated behind the vehicle as it moves, NewScientist said.
Hence, instead of making these vehicles more wedge-shaped, significant fuel economies can be made by modifying their behind.
Salari has designed a set of fans to be fitted to the back of a cab or trailer that injects air in a way that significantly reduces the turbulence it generates. This should in turn improve fuel economy, although the patent does not say the scale of the potential gains.
