NASA uses Aircraft mounted instruments to examine growing Deltas in Louisiana

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Louisiana coastline is sinking under the Gulf of Mexico at the rate of about one football field of land every hour (about 18 square miles of land lost in a year). But within this sinking region, two river deltas are growing. The Atchafalaya River and its diversion channel, Wax Lake Outlet, are gaining about one football field of new land every 11 and 8 hours, respectively (1.5 and 2 square miles per year).

Last fall, a team from NASA’s Jet Propulsion Laboratory in Pasadena, California, showed that radar, lidar and spectral instruments mounted on aircraft can be used to study the growing deltas, collecting data that can help scientists better understand how coastal wetlands will respond to global sea level rise.

The History of Renfroe Station on the Red River, 1780 – Part 2

 

Clarksville Tennessee HistoryClarksville, TN – In 1780 a group of 300 daring pioneers decided to journey upon the Tennessee River and the Cumberland River in flatboats and canoes.

The destination for some of them would be present day Montgomery County, upon the Red River at the mouth of Passenger Creek. Yet, in order to arrive at their destination they had to guide their boats through a frontier full of Native Americans determined to attack them.

Why would they attempt such an endeavor which seemed to almost promise violence, deprivation, and other hardships?

NASA to test Space Launch System’s Largest Fuel Tank

 

Written by Tracy McMahan
NASA’s Marshall Space Flight Center

NASA - National Aeronautics and Space AdministrationHuntsville, AL – Major construction is complete on NASA’s largest new Space Launch System structural test stand, and engineers are now installing equipment needed to test the rocket’s biggest fuel tank.

The stand is critical for ensuring SLS’s liquid hydrogen tank can withstand the extreme forces of launch and ascent on its first flight, and later on the second flight, which will carry up to four astronauts in the Orion spacecraft on a journey around the moon, into the deep-space proving ground for the technology needed for the journey to Mars.

Bobo manages SLS structural strength testing, and Nichols is lead test engineer for the SLS liquid hydrogen tank, which the stand will subject to the forces it must endure during launch and flight.

NASA’s Orion Spacecraft to make leaps forward in 2017

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – From the beginning of assembly work on the Orion crew module at NASA’s Kennedy Space Center in Florida to testing a range of the spacecraft systems, engineers made headway in 2016 in advance of the spacecraft’s 2018 mission beyond the moon.

A look at the important milestones that lie ahead in the next year give a glimpse into how NASA is pressing ahead to develop, build, test and fly the spacecraft that will enable human missions far into deep space.

American Heart Association says Popular Heartburn Medication may increase Ischemic Stroke Risk

 

American Heart Association Meeting Report

American Heart AssociationNew Orleans, LA – A popular group of antacids known as proton pump inhibitors, or PPIs, used to reduce stomach acid and treat heartburn may increase the risk of ischemic stroke, according to preliminary research presented at the American Heart Association’s Scientific Sessions 2016.

“PPIs have been associated with unhealthy vascular function, including heart attacks, kidney disease and dementia,” said Thomas Sehested, M.D., study lead author and a researcher at the Danish Heart Foundation in Copenhagen, Denmark. “We wanted to see if PPIs also posed a risk for ischemic stroke, especially given their increasing use in the general population.”

Amputation risks highest amongst Poor and Black Peripheral Artery Disease Patients according to American Heart Association

 

American Heart Association Meeting Report

American Heart AssociationNew Orleans, LA – Poverty and black race are independently predictive of greater amputation risk among patients with narrowing of the blood vessels, or peripheral artery disease (PAD), according to preliminary research presented at the American Heart Association’s Scientific Sessions 2016.

PAD is a serious disease that occurs when fat, cholesterol, and other substances accumulate in blood vessels away from the heart, restricting blood flow.

American Heart Association says Yo-Yo Dieting Dangerous even if you’re not Overweight

 

American Heart Association Meeting Report

American Heart AssociationNew Orleans, LA – Repeatedly losing and regaining weight, known as weight cycling or yo-yo dieting, may increase the risk of death from heart disease among postmenopausal women who were of normal weight at the start of the study, according to research presented at the American Heart Association’s Scientific Sessions 2016.

Normal weight postmenopausal women at the start of the study who lost and regained weight had: 3 and ½ times higher risk for sudden cardiac death and nearly 66% increased risk for coronary heart disease death. (American Heart Association) «Read the rest of this article»

American Heart Association reports Poor Sleep may increase risk for Irregular Heart Rhythms

 

American Heart Association Meeting Report

American Heart AssociationNew Orleans, LA – Disruptions in sleep may be raising your risks of an irregular heartbeat, known as atrial fibrillation (AF), according to preliminary research presented at the American Heart Association’s Scientific Sessions 2016.

Obstructive sleep apnea, sleep interrupted by pauses in breathing, is a known risk for atrial fibrillation – an irregular heartbeat that can lead to strokes, heart failure and other heart-related complications. But whether there’s a relationship between disrupted sleep and atrial fibrillation even when there’s no sleep apnea is unclear.

Poor sleep – even if you don’t have sleep apnea – may be linked to higher risks of developing an irregular heartbeat. (American Heart Association)
