Washington, D.C. – NASA has selected a first-of-its-kind Earth science mission that will extend our nation’s lead in measuring key greenhouse gases and vegetation health from space to advance our understanding of Earth’s natural exchanges of carbon among the land, atmosphere and ocean.
The primary goals of the Geostationary Carbon Cycle Observatory (GeoCARB), led by Berrien Moore of the University of Oklahoma in Norman, are to monitor plant health and vegetation stress throughout the Americas, and to probe, in unprecedented detail, the natural sources, sinks and exchange processes that control carbon dioxide, carbon monoxide and methane in the atmosphere.
Tennessee Department of Health Cautions Travel by Pregnant Women and their Sexual Partners as Zika Virus Disease is a Threat in Vacation Areas
Nashville, TN – Seasonal frosts that help reduce mosquito activity in Tennessee will arrive soon, bringing some relief from the blood-feeding insects.
Mosquitoes in Tennessee are currently known to transmit diseases such as West Nile virus and La Crosse Encephalitis. With 45 cases of travel-related Zika Virus Disease confirmed thus far this year in Tennessee, there is yet another reason to “Fight the Bite.”
Tennessee Department of Health says Zika Virus Disease raises awareness about Preventing Birth Defects
Microcephaly One of Many Defects that Deserve Attention
Nashville, TN – Until a recent outbreak of Zika virus disease was associated with babies born with microcephaly, many had not heard of the birth defect. Tennessee Department of Health data show approximately 45 to 50 cases occur in Tennessee each year.
Babies with microcephaly are born with heads that are smaller than expected. This can be associated with developmental delays, intellectual disabilities, problems with hearing or vision and seizures.
Tennessee Department of Health says Spring Breakers, Mission Trip Members need Heightened Awareness of Mosquito-Borne Diseases
“Fight the Bite” Strategies Crucial in Preventing Illness
Nashville, TN – Across Tennessee, thousands of college students, members of faith organizations, healthcare professionals and others are planning spring or summer trips to warmer locations for fun and/or for mission work.
The Tennessee Department of Health cautions travelers headed soon to these warmer climates to have an increased awareness about diseases spread by mosquitoes and to make mosquito bite prevention an essential part of their trip planning.
AAA urges Americans to be informed when shaping 2016 travel plans
Knoxville, TN – Media publicity regarding terrorism, the stock market, and now the Zika virus is weighing on the minds of travelers, many of whom are turning to AAA for advice on whether they should alter their vacation plans.
AAA always encourages Americans to be cautious when traveling the world, and to be aware of any health or security alerts before leaving. Although much has been made about the Zika virus, and travelers should stay informed, Federal health officials have not issued travel restrictions to those countries with active virus transmission.
TDH Urges Residents & Travelers to Have Heightened Awareness about Protection Strategies
Nashville, TN – The Tennessee Department of Health today has received confirmation from the Centers for Disease Control and Prevention of the first person in the state to test positive for Zika virus disease. The individual had recently traveled to South America before returning to east Tennessee.
“We have been expecting an imported case of Zika virus disease and we believe more infections are likely as people travel to and from areas where the disease is currently being transmitted,” said TDH Commissioner John Dreyzehner, MD, MPH.
Areas with Warmer Climates Present Need for Increased Protection Strategies
Nashville, TN – The Tennessee Department of Health cautions travelers headed to Mexico, Central America, South America, Hawaii and Caribbean islands including Puerto Rico and other locations with year-round warm climates to have increased awareness about the threat of mosquito-borne illnesses and to take appropriate bite protection measures.
The cautionary message follows a recommendation from the U.S. Centers for Disease Control and Prevention that all pregnant women consider postponing travel to areas where an emerging health threat, zika virus infection, is ongoing.

Pasadena, CA – The current strong El Niño brewing in the Pacific Ocean shows no signs of waning, as seen in the latest satellite image from the U.S./European Ocean Surface Topography Mission (OSTM)/Jason-2 mission.
El Niño 2015 has already created weather chaos around the world. Over the next few months, forecasters expect the United States to feel its impacts as well.
The latest Jason-2 image bears a striking resemblance to one from December 1997, by Jason-2’s predecessor, the NASA/Centre National d’Etudes Spatiales (CNES) Topex/Poseidon mission, during the last large El Niño event. Both reflect the classic pattern of a fully developed El Niño. The images can be viewed at:

Washington, D.C. – In the days before light bulbs, farmers relied on moonlight to help them harvest their crops. Many crops ripen all at once in late summer and early autumn so farmers found themselves extremely busy at this time of year. They had to work after sundown. Moonlight became an essential part of farming, and thus, the Harvest Moon was born.
According to folklore, the Harvest Moon is the full Moon that falls closest to the autumnal equinox, the hectic beginning of northern autumn. In 2015, the Moon is full on September 28th, less than a week after the equinox of September 23rd. The coincidence sets the stage for a nice display of harvest moonlight.

Greenbelt, MD – Coming soon for the first time in more than 30 years: you’ll be able to witness a supermoon in combination with a lunar eclipse.
Late on September 27th, 2015, in the U.S. and much of the world, a total lunar eclipse will mask the moon’s larger-than-life face for more than an hour.
But what is this behemoth of the night sky? Not a bird, not a plane, it’s a supermoon! Although this incarnation of the moon comes around only once every year, it’s not as mysterious as you might think.
