A man walks in the early morning to start his day picking tea leaves at a plantation in Nandi Hills, in Kenya's highlands region west of capital Nairobi, November 5, 2014. Emerald-coloured tea bushes blanketing the rolling hills of Nandi County have long provided a livelihood for small-scale farmers, helping make Kenya one of the world's biggest tea exporters. But ideal weather and bigger harvests, instead of producing bumper earnings, have led to a glut of Kenya's speciality black tea. (Photo by Noor Khamis/Reuters)

In this handout image provided by Ogilvy, a burger made from cultured beef, which has been developed by Professor Mark Post of Maastricht University in the Netherlands (pictured) is shown to the media during a press conference on August 5, 2013 in London, England. The in-vitro burger, cultured from cattle stem cells, the first example of what its creator says could provide an answer to global food shortages and help combat climate change, was fried in a pan and tasted by two volunteers. The burger is the result of years of research by Dutch scientist Mark Post, a vascular biologist at the University of Maastricht, who is working to show how meat grown in petri dishes might one day be a true alternative to meat from livestock.The meat in the burger has been made by knitting together around 20,000 strands of protein that has been cultured from cattle stem cells in Post's lab.

Space tourism companies are employing designs including winged vehicles, vertical rockets with capsules and high-altitude balloons. While developers envision ultimately taking people to orbiting habitats, the moon or beyond, the immediate future involves short flights into or near the lowest reaches of space without going into orbit.
