A de-snare mission about a year ago in the northern part of our study area. Unfortunately this is an all to common part of the job. Commercial bushmeat is in high demand so poachers set snares for antelope but indiscriminately lions, hyena, wild dog, giraffe, etc get caught as well. Usually they break the snare off the anchor, thus carrying wire around their neck or limbs. Unless action is taken these animals most often die or lose a limb. Once the snare is removed and the wound treated, they usually make a full recovery. photo credit @martinedstrom and visit his page to learn more about their cool virtual reality work here in South Luangwa!
This is Johnathan Merkle and Ben Goodheart of the Zambian Carnivore Programme. They're inspecting the wound of a male lion wounded by a snare. After tracking down the lion and having the vet sedating it with a tranquilizer dart, the scientists have about 50 minutes to work on the lion before they need to give him space to wake up. Removing the snare, cleaning the wound and giving the lion antibiotics to help ward of infection, the scientists hope to give the lion a better chance of survival despite being the victim of a snare.
As you can imagine, working closely with the Zambia Carnivore Programme was an impressive experience.
Peering into the origins of our universe @NationalGeographic#NatGeoFest#explorer 🤓🏻
. #ICYMI / #FYI Ultimately, the goal of the Cosmology Large Angular Scale Surveyor (CLASS) telescope is to make a precise determination of cosmic dawn—when the stars in the first galaxies formed—and to characterize what happened in the first trillionth of a second when the universe formed. Initially appearing as high energy radiation, that light has cooled with the expansion of the universe and now appears in the microwave part of the electromagnetic spectrum.
This ancient radiation—called the cosmic microwave background, or CMB—was first predicted by Ralph Alpher at the @JohnsHopkinsU Applied Physics Laboratory just after World War II. Its discovery in 1964 resulted in two Nobel Prizes. Three space missions have since been dedicated to the study of the CMB, resulting in two more Nobel Prizes. The CMB is important because it travels through space for 13.8 billion years, carrying with it an image of the infant universe.
The most popular current theory of the origin of the universe is called "inflation theory." Inflation theory holds that the universe grew exponentially from quantum fluctuations to astronomical scales producing gravitational waves. Gravitational waves were discovered recently from the merging of two black holes. Detecting the gravitational waves from inflation will require a very different kind of detector, one that nature itself has provided. Gravitational waves from the origin of the universe induce a specific kind of polarization, or directional pattern of the CMB. That pattern is what the CLASS telescope is designed to observe.
The CLASS observatory consists of two 30-foot-tall towers, each holding two microwave instruments including optics, a detector system that uses a device designed and recently patented by investigators at Johns Hopkins University and NASA, and a device that rapidly switches the polarization—a bit like switching the direction of polarized glasses.
Celebrating THE SPACE ISSUE @natgeo! #explorers 🏻🏿🏻🏽🏼 •
"A new space race is under way, fueled by scientists, visionaries, and dreamers who have set their sights on the moon and beyond. Meet the teams that are competing for a multimillion-dollar payday—and bragging rights. Success could mark the start of a new lunar industry, which has preservationists hurrying to protect the artifacts left behind after the first moon landings. And while we look to the moon for inspiration, astronaut Scott Kelly reflects on a year of looking back at Earth from the International Space Station in an exclusive excerpt from his upcoming memoir, Endurance." #thespaceissue#natgeospace#natgeo#natgeofest#NASA#ISS
