Japanese researchers cultivated small pieces of tissue from the testes of baby mice on a gel bathed in nutrients. After several weeks they collected viable sperm from the tissue. The sperm appeared to be completely healthy and were used in IVF treatments to produce 12 live mouse pups that went on to have young of their own. Seven of the mice were born after sperm heads were transferred into 23 eggs using a technique called round spermatid injection, and another five were born after 35 eggs were fertilised using intracytoplasmic sperm injection (Icsi), a common IVF procedure.
Importantly, the scientists retrieved healthy sperm from tissue that was cultivated after being frozen for up to 25 days, suggesting that cold storage did not harm the cells. The work, reported in the journal, Nature, is the most successful attempt yet to grow mammalian sperm from testicular tissue in the laboratory.
Allan Pacey, a senior lecturer in andrology at Sheffield University, said: "It is not totally clear how sperm are formed and why in some men it doesn't work properly. This could help discover new drugs or treatments to stimulate infertile men to produce more or better sperm. It also may help preserve the fertility of some males."

She received a lot of press fame recently thanks to her Menstruation Machine, Takashi's Take.
Fitted with a blood dispensing mechanism and lower-abdomen-stimulating electrodes (the same used by your uncle to muscle his abs while watching tv on the sofa, only that Hiromi maxed out the power of the contractions), the Menstruation Machine simulates the pain and bleeding of an average 5 day menstruation.Detail of the Menstruation Machine
The machine could be worn by men who desire to feel closer to women and experience what they have to go through, but also by women when menstruation becomes obsolete in the future and the process becomes a mere ritual of gender and identity.
The artist made a music video to illustrate how and by whom the machine can be used.
The video 'Menstruation Machine - Takashi's Take' stars Takashi, a boy who builds the machine in an attempt to understand better what the girls he hang around with experience every month.
Trailer of Air Doll, a film directed by Hirokazu Koreeda and based on a manga by Yoshiie Gōda.
Hideo, who lives alone, owns a life-size air doll, which suddenly finds herself with a heart. Everything is new to her in the world outside Hideos house. She meets all kinds of people. The world is filled with so many beautiful things, but everyone seems to have some kind of hollowness, just as she has. In the morning, she pumps herself up, and takes a walk.
One afternoon, she meets Junichi who works at a rental video store, and instantly falls in love with him. A first date. New words she learns from him. She starts working with him at the store, enjoys talking and being with him. Everything seems to be going perfect, until something unexpected happens to the doll.
This is a story about a new form of love.
Triumph International, maker of the quirkiest (a diplomatic version of the word 'ridiculous') and most puzzling bras in the world, is offering a new kind of support for Japanese women on the prowl for a husband.
Their latest bra features an electronic nuptial timepiece, putting women seeking spouses literally on the clock. If an engagement ring is inserted into the mechanism, the countdown stops and the bra plays Felix Mendelssohn's "The Wedding March." The bra also includes holders for the traditional seal some people use to sign off contracts and a pen for any possible nuptial agreement.
Triumph spokeswoman Keiko Masuda said the product, which is not for sale, would suit modern Japanese women who are no longer content to sit and wait for a potential husband to approach them.
The Japan Aerospace Exploration Agency (JAXA) has developed a next-generation space toilet, which they hope to complete within the next five years.
Clean and easy to use, the envisioned space toilet is designed to be worn like a diaper around the astronaut’s waist at all times. Sensors detect when the user relieves him or herself, automatically activating a rear-mounted suction unit that draws the waste away from the body through tubes into a separate container. In addition to washing and drying the wearer after each use, the next-generation space toilet will incorporate features that eliminate unwanted sound and odor.
The developers indicate their next-generation space toilet may also prove useful in earthbound settings — particularly in hospitals with bedridden patients.
The current ISS toilet is a Russian-built, western-style commode that sucks waste away like a vacuum cleaner. Use of that toilet requires practice before heading to space, particularly because an improperly seated user has the potential to create a messy situation.

Since launching two weeks ago on Rakuten, a major Japanese web shopping mall, the Wishroom shop has sold over 300 men's bras for 2,800 yen (£20) each.
"I like this tight feeling. It feels good," Wishroom representative Masayuki Tsuchiya said.
Wishroom Executive Director Akiko Okunomiya said she was surprised at the number of men who were looking for their inner woman. "I think more and more men are becoming interested in bras. Since we launched the men's bra, we've been getting feedback from customers saying 'wow, we'd been waiting for this for such a long time'," she said.
Rakuten say the bra, which comes in black, pink and white, will “make you feel more gentle” and “give you a sense of relief - because that is a very important feeling to have”.
The underwear has stirred a heated debate online with more than 8,000 people debating the merits of men wearing bras in one night on Mixi, Japan's top social network website.
