Washington, D.C. – Mission controllers at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, have confirmed that MESSENGER slammed into the surface of Mercury on April 30th at 3:26pm EDT.
It had used the last of its propellant on April 24th and could no longer maintain a stable orbit. Traveling some 8,750 mph, the plummeting spacecraft made an unseen crater on the side of the planet facing away from Earth.
New American Heart Association Guidelines recommends Diets high in Fruit, Vegetables, Whole Grains and Nuts among factors to lower first-time Stroke Risk
Dallas, TX – Eating Mediterranean or DASH-style diets, regularly engaging in physical activity and keeping your blood pressure under control can lower your risk of a first-time stroke, according to updated AHA/ASA guideline published in the American Heart Association’s journal Stroke.
“We have a huge opportunity to improve how we prevent new strokes, because risk factors that can be changed or controlled — especially high blood pressure — account for 90 percent of strokes,” said James Meschia, M.D., lead author of the study and professor and chairman of neurology at the Mayo Clinic in Jacksonville, Florida.
Nashville, TN – Americans’ love for salt is having a dramatic impact on their health. The average American takes in more than 3,400 milligrams of sodium each day—almost 2,000 milligrams more than the limit recommended by the American Heart Association (1500 mg/day).
Sodium is an essential nutrient and a little salt can be part of a healthy diet, but the amounts we are eating are far too high and can increase the risk of high blood pressure, heart disease, stroke, and other health problems.
“I Love You Salt, But You’re Breaking My Heart” campaign encourages people to pledge to reduce sodium, to lower risk for heart problems, stroke
Nashville, TN – Take the pledge – to reduce your salt intake. It may save your life.
Americans eat too much salt, and most have no idea how much they are eating, according to new consumer research by the American Heart Association.
Nearly all of the 1,000 people surveyed by the American Heart Association (97 percent) either underestimated or could not estimate how much sodium they eat every day. Too much sodium in the diet can increase risk for high blood pressure, stroke, heart disease and other major health problems.
American Heart Association reports processed Red Meat linked to higher risk of Heart Failure, Death in Men
Dallas, TX – Men who eat moderate amounts of processed red meat may have an increased risk of incidence and death from heart failure, according to a study in Circulation: Heart Failure, an American Heart Association journal.
Processed meats are preserved by smoking, curing, salting or adding preservatives. Examples include cold cuts (ham, salami), sausage, bacon and hot dogs.
San Francisco, CA – Overweight or obese teenagers who eat lots of salty foods may show signs of faster cell aging, according to research presented at the American Heart Association’s Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions 2014.
“Lowering sodium intake, especially if you are overweight or obese, may slow down the cellular aging process that plays an important role in the development of heart disease,” said Haidong Zhu, M.D., Ph.D., lead author of the study and assistant professor of pediatrics at Medical College of Georgia, Georgia Regents University in Augusta, GA.
San Francisco, CA – Teaching people how to flavor food with spices and herbs is considerably more effective at lowering salt intake than having them do it on their own, according to research presented at the American Heart Association’s Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions 2014.
NASA to launch Lunar Atmosphere and Dust Environment Explorer (LADEE) to study Twilight Rays on the Moon
Washington, D.C. – Back in the 60s and 70s, Apollo astronauts circling the Moon saw something that still puzzles researchers today. About 10 seconds before lunar sunrise or lunar sunset, pale luminous streamers would pop up over the gray horizon. These “twilight rays” were witnessed by crew members of Apollo 8, 10, 15 and 17.
Back on Earth, we see twilight rays all the time as shafts of sunlight penetrate evening clouds and haze. The “airless Moon” shouldn’t have such rays, yet the men of Apollo clearly saw them.
Greenbelt, MD – Heliophysics nuggets are a collection of early science results, new research techniques, and instrument updates that further our attempt to understand the sun and the dynamic space weather system that surrounds Earth.
On August 11th and 12th, 2013, the annual Perseid meteor shower will peak, filling the sky with streaks of light, commonly known as shooting stars. Such visually stunning showers are actually but the tip of the iceberg when it comes to meteoroids slamming into Earth’s atmosphere: Some 10 to 40 tons of material of invisible meteoric dust enters the atmosphere from interplanetary space every day.
Dallas, TX – The risk of elevated blood pressure among children and adolescents rose 27 percent during a thirteen-year period, according to new research in the American Heart Association journal Hypertension.
Higher body mass, larger waistlines and eating excess sodium may be the reasons for the elevated blood pressure readings, researchers said.
High blood pressure is a risk factor for stroke, heart disease and kidney failure — accounting for about 350,000 preventable deaths a year in the United States.
