Scientists looking for signs of life in the universe -- as well as another planet like our own -- are a lot closer to their goal than people realize.
That was the consensus of a panel on the search for life in the universe held at NASA headquarters Monday in Washington. The discussion focused not only on the philosophical question of whether we're alone in the universe but also on the technological advances made in an effort to answer that question.
"We believe we're very, very close in terms of technology and science to actually finding the other Earth and our chance to find signs of life on another world," said Sara Seager, a MacArthur Fellow and professor of planetary science and physics at the Massachusetts Institute of Technology.
In an ongoing series on hybridizing fruit trees, Syracuse University sculptor Sam Van Aken's Tree of 40 Fruit is true to its name. Most of the year, it looks pretty ordinary, but in the spring, the tree blossoms display various tones of pink, crimson, and white. Then, from July through October, it bears 40 different types of stone fruit, including almonds, apricots, cherries, nectarines, peaches, and plums.
The feat is accomplished by grafting together several different varieties, including native fruit, heirlooms, and antiques, some of which are centuries-old, Aken tells Epicurious.
