The Secret of The Blood Falls of Antarctica

     From a crack in the Taylor Glacier in the McMurdo Dry Valleys of Antarctica flows a curious blood-red colored water. When it was first discovered by geologist Griffith Taylor in 1911, the color was thought to have come from an algae. The source of the red color was later discovered to be an iron-rich underground saltwater lake that was trapped by the encroaching glacier at least 1.5 million years ago. The temperature of the water is -5 Celsius, but it's so salty that it doesn't freeze.
     But the Blood Falls houses another secret, which scientists from Harvard University have started to uncover - it's home to an entire ecosystem of bacteria, trapped for millennia in conditions that are extremely inhospitable to life.
     Roughly two million years ago, the Taylor Glacier sealed beneath it a small body of water which contained an ancient community of microbes. Trapped below a thick layer of ice, they have remained there ever since, isolated inside a natural time capsule. With no light or free oxygen and little heat, the microbes had no chance of getting energy through photosynthesis. Instead, the microbes started to live off the minerals that were trapped in the lake with them, evolving independently of the rest of the living world.
     The existence of the Blood Falls ecosystem shows that life can exist in the most extreme conditions on Earth.
     The fascinating secrets that remain locked inside the inaccessible sub-glacier lake will help scientist understand the range of conditions to which life can adapt and to advance assessment of the possibility of life elsewhere in the solar system, in places such as Mars or Europa, an ice-covered moon of Jupiter. Indeed, scientists of the NASA Astrobiology Institute speculate that these worlds could contain subglacial liquid water environments favorable to hosting elementary forms of life, which would be better protected at depth from ultraviolet and cosmic radiation than on the surface.

Nola Ochs, World's Oldest Masters Degree at Age 98
                                             
     Nola (Hill) Ochs (born November 22, 1911) is an American college graduate. On May 14, 2007 she became a Guinness World Record holder as the world's oldest college graduate when she received her diploma at Fort Hays State University (FHSU) in Hays, Kansas. She earned a general studies degree with an emphasis in history, graduating alongside her granddaughter, Alexandra Ochs, who was 21 years old at the time.
      From Jetmore, Kansas, Ochs was born in 1911 and took her first college class from FHSU in 1930. Nola and her husband, Vernon Ochs, raised four sons (who have given her 13 grandchildren and 15 great-grandchildren) on the family farm. She took college courses again from Dodge City Community College in Dodge City, Kansas after her husband of 39 years died in 1972. After learning that she was only 30 hours shy of a bachelor’s degree, Nola moved 100 miles from the family farm to an FHSU university apartment in Hays to finish her degree. During her first year at Fort Hays, Ochs told news reporters that after she graduated, she wanted to be a storyteller on a cruise ship.
      Ochs was named the 2007 Kansas Woman Leader of the Year and was given her diploma by Kansas Governor, Kathleen Sebelius. Features on Ochs aired on The Early Show, MSNBC, and CBS News among others. She even earned a spot on The Tonight Show one week after she graduated, sharing a laugh with Jay Leno.
     After graduation, Princess Cruises hired her as a guest lecturer on a nine-day Caribbean cruise. She shared the adventure with her granddaughter, Alexandra. After taking time to help with the family wheat harvest, Ochs started pursuing her master’s degree in liberal studies from Fort Hays State University in August 2007. She received her master's on May 15, 2010, making her the oldest recipient of a master's degree at age 98. According to an August 11, 2006 press release from FHSU, Ochs said “I don't keep track of my age, but I can tell you I was born in November of 1911.” She also commented, “I've led a long, interesting life. We went through the dust storms. We had some difficult times in our marriage, financially. But it's been the Lord's will that I've lived this long life, and I thank Him kindly for it.” As of her 100th birthday in November 2011 she was an M.A Student at FHSU and a Graduate Teaching Assistant.
