Austin Peay State University Students, Professors publish paper about recent work with Bacteriophages

 

Austin Peay State University - APSUClarksville, TN – Austin Peay State University (APSU) biology students and professors continue to find success in their work with bacteria-infecting viruses called bacteriophages.

This spring, 11 undergraduate and graduate students worked with APSU’s Dr. Sergei Markov to publish a paper that shares the team’s work with the three bacteriophages they found in Clarksville and lovingly named Danno, Otwor and Scumberland.

NASA says Growing Plants on International Space Station has applications on Earth

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA states that understanding the effects of gravity on plant life is essential in preparing for human exploration beyond low-Earth orbit.

The ability to produce high-energy, low-mass food sources during spaceflight will enable the maintenance of crew health during long-duration missions while having a reduced impact on resources necessary for long-distance travel.

Thanks to Donald Trump Administration, United States Has a Coronavirus Plan of Action

 

The White HouseWashington, D.C. – “While the potential damages of a pandemic are in general large, the analyses thus far on the coronavirus are largely global in nature and fail to account for the rapid federal response to secure the country and create a cure,” Bradley Blakeman and Christos Makridis write for The Washington Times.

“That’s evident in a recent Gallup poll that found 77 percent of the population is very or somewhat confident in the government’s ability to handle the coronavirus, up significantly from 58 percent from the Ebola virus in 2014 and 67 percent from the swine flu in 2009,” they explain.

American Heart Association reports Alarming number of Heart Infections tied to Opioid Epidemic

 

American Heart AssociationDallas, TX – According to new research published in the Journal of the American Heart Association, the open access journal of the American Heart Association, an alarming number of people nationwide are developing infections of either the heart’s inner lining or valves, known as infective endocarditis, in large part, due to the current opioid epidemic.

As the nationwide opioid epidemic continues, more young people are developing a life-threatening heart infection that can result from drug abuse. (American Heart Association)

American Heart Association says New research suggests Gut Bacteria may be linked to High Blood Pressure, Depression

 

American Heart AssociationNew Orleans, LA – A study of bacteria in the gut identified differences between people with high blood pressure compared to those with high blood pressure plus depression, according to preliminary research presented at the American Heart Association’s Hypertension 2019 Scientific Sessions. 

“People are ‘meta-organisms’ made up of roughly equal numbers of human cells and bacteria. Gut bacteria ecology interacts with our bodily physiology and brains, which may steer some people towards developing high blood pressure and depression,” said Bruce R. Stevens, Ph.D., lead author of the study and professor of physiology & functional genomics, medicine and psychiatry at the University of Florida College of Medicine in Gainesville, Florida.

This infographic illustrates the connection between the brain, central nervous system and other organs and how they interact with a person's gut microbes to show different patterns - from people with high blood pressure plus depression; high blood pressure without depression; depression with healthy blood pressure; or healthy subjects without depression or high blood pressure.

NASA scientists study Aerogel for building habitats on Mars

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Red Planet is an inhospitable world. NASA says growing crops on Mars is far easier in science fiction than it will be in reality. Among other challenges, subzero temperatures mean water can persist on the surface only as ice, and the planet’s atmosphere offers little protection to plants (or people) from the Sun’s radiation.

Raising crops on Mars is far easier in science fiction than it will be in real life: The Red Planet is an inhospitable world. Among other challenges, subzero temperatures mean water can persist on the surface only as ice, and the planet’s atmosphere offers little protection to plants (or people) from the Sun’s radiation.

Scientists are exploring how aerogel, a translucent, Styrofoam-like material, could be used as a building material on Mars. Aerogel retains heat; structures built with it could raise temperatures enough to melt water ice on the Martian surface. (NASA/JPL-Caltech)

2018 Spinoff publication shows NASA Space Technology at work on Earth

 

Written by Gina Anderson
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The 2018 edition of NASA’s annual Spinoff publication, released Tuesday, features 49 technologies the agency helped create that are used in almost every facet of modern life.

These include innovations that help find disaster survivors trapped under rubble, purify air and surfaces to stop the spread of germs, and test new materials for everything from airplanes to athletic shoes.

Scientists at NASA’s Jet Propulsion Laboratory used their expertise at detecting faint signals in satellite data to develop a device capable of detecting human heartbeats underneath piles of rubble. The technology has been licensed by multiple companies, including R4 Inc. After a magnitude 7.8 earthquake hit Ecuador in April of 2016, R4 president David Lewis Sr. brought the company’s FINDER system to look for trapped victims. Here, Lewis, right, shows local firefighters how to operate the system. (R4 Inc.)

Mark Britton talked about Civil War Medicine at Clarksville’s Fort Defiance, Saturday

 

Fort Defiance Interpretive CenterClarksville, TN – Saturday afternoon at the Fort Defiance Civil War Park and Interpretive Center a small group gathered to watch Mark Britton talk about Civil War era doctors, the tools, medicines, and methods they used.

“I’m not a doctor, but I could have been in the 19th century,” Britton said. “I’ve only been collecting and studying medical supplies and procedures for the last 10 to 12 years, but I have always been a fan of history, all types of history, ancient and recent.”

A presentation on life in the 1800's at Fort Defiance this weekend, with guest speaker Mark Britton.
