NASA studies Mars Canyons for signs of liquid water

NASA - National Aeronautics and Space AdministrationPasadena, CA – Puzzles persist about possible water at seasonally dark streaks on Martian slopes, according to a new study of thousands of such features in the Red Planet’s largest canyon system.

The study published today investigated thousands of these warm-season features in the Valles Marineris region near Mars’ equator. Some of the sites displaying the seasonal flows are canyon ridges and isolated peaks, ground shapes that make it hard to explain the streaks as resulting from underground water directly reaching the surface.

American Heart Association Comment strongly refutes study findings on sodium consumption

 

American Heart AssociationDallas, TX – The American Heart Association strongly refutes the findings of a May 20th, 2016 article in The Lancet by Mente, et al, that suggest low sodium intake is related to a higher risk of heart disease and death.

On the contrary, the link between excessive sodium and high blood pressure – as well as higher risks of heart disease, stroke, heart failure and kidney disease – is indisputable. Lowering sodium is more important than ever.

American Heart Association reports Healthy Diet may reduce High Blood Pressure risk in Pregnancy-Related Diabetes

 

American Heart AssociationDallas, TX – Women with pregnancy-related diabetes  (gestational diabetes) are at greater risk of developing high blood pressure later in life; however, a healthy diet may significantly reduce that risk, according to new research in the American Heart Association’s journal Hypertension.

Researchers studied 3,818 women with a history of pregnancy-related diabetes enrolled in the Nurses’ Health Study II as a part of the ongoing Diabetes & Women’s Health Study. Over 22 years of follow-up, 1,069 women developed high blood pressure, which in turn increased their risk of having a heart attack or stroke.

NASA’s Dawn Spacecraft photos reveal details of Dwarf Planet Ceres over 200 years since it’s discovery

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New Year’s Day, 1801, the dawn of the 19th century, was a historic moment for astronomy, and for a space mission called Dawn more than 200 years later. That night, Giuseppe Piazzi pointed his telescope at the sky and observed a distant object that we now know as Ceres.

Today, NASA’s Dawn mission allows us to see Ceres in exquisite detail. From the images Dawn has taken over the past year, we know Ceres is a heavily cratered body with diverse features on its surface that include a tall, cone-shaped mountain and more than 130 reflective patches of material that is likely salt. But on that fateful evening in 1801, Piazzi wasn’t sure what he was seeing when he noticed a small, faint light through his telescope.

Giuseppe Piazzi used this instrument, called a Ramsden Circle, to discover Ceres on January 1, 1801. The telescope is on display at the Palermo Observatory in Sicily. (NASA/JPL-Caltech/Palermo Observatory)

NASA’s Mars Reconnaissance Orbiter confirms Liquid Flowing Water on Mars

 

Written by Guy Webster / DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars.

Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time.

They darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons. They appear in several locations on Mars when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius), and disappear at colder times.

Dark, narrow streaks on Martian slopes such as these at Hale Crater are inferred to be formed by seasonal flow of water on contemporary Mars. The streaks are roughly the length of a football field. (NASA/JPL-Caltech/Univ. of Arizona)

American Heart Association says the result of eating too much Salt can be measured in Blood Pressure

 

American Heart AssociationDallas, TX – People who gradually increase the amount of salt in their diet and people who habitually eat a higher salt diet both face an increased risk of developing high blood pressure, according to a study published in the Journal of the American Heart Association.

In a Japanese study of more than 4,000 people who had normal blood pressure, almost 23 percent developed high blood pressure over a three year period. Those who ate the most salt were the most likely to have high blood pressure by the end of the study. Participants who gradually increased their sodium intake also showed gradually higher blood pressure.

AAA gives 5 Tips for Cleaning your Car after the Thaw

 

AAAKnoxville, TN – Your shiny car is probably three dirty shades of grey after driving through the snow, slush and salt during the last two weeks.  In fact, your car could be corroding in some secret places, and reversing the effects may not be as easy as a simple car wash.

“In addition to the build-up on the body of the vehicle, damage can occur to the undercarriage as well,” said Jack Wilson, field business manager, Tennessee Approved Auto Repair. “Proper cleaning can help combat corrosion to vital parts such as brake lines and fuel tanks, and time could be a factor.” «Read the rest of this article»
