Two medevac companies in Afghanistan have participated in a trial program to administer blood products to wounded Soldiers during en-route flight care and movement to a medical facility. Army UH-60 medevac Black Hawk helicopters, like the ones pictured here, now carry blood products during medevac missions to give casualties a better chance of survivability.
These "trees" are part of Supertree Grove, an installment of Singapore's Gardens by the Bay. They are made up of a combination of plants and mechanics that are designed to be environmentally friendly. There is also a walkway that connects the trees so that the public can view the sights from a different perspective. I would really like to see these in real life some day!
