and here's a breakdown of how it works (explanation begins at 4:14):
The news: A game-changing condom that kills almost all sexually transmitted infections, including herpes, HIV and HPV is one step closer to hitting the market. The Australian market, that is.
Ansell, the Australian prophylactic company, will manufacture a condom laced with the antimicrobial VivaGel lubricant. Australia's version of the Food and Drug Administration, the Australian Therapeutic Goods Administration, gave the product a Conformity Assessment Certification, meaning that it could be on the market within months. The gel is proven effective in killing 99.9% of sexually transmitted infections (STIs).
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.
