Oregon State University (OSU) animal researchers in conjunction with the U.S. Department of Agriculture‘s (USDA) Dubois, Idaho-based Sheep Experiment Station released a report on an OSU-USDA study which was initiated in 1995 after breeders asked the government to determine why some rams bought as breeding studs showed no interest in females. The researchers are working under a $2.8 million grant from the National Institutes of Health in hopes of developing a test which can determine the likelihood of a ram being female-oriented before it is sold as a stud.

By studying difference in the animal’s brains after slaughter, the study also showed what could be a biological determiner for what makes a ram male-oriented instead of female-oriented sexually. The scientists’ results showed that the anterior preoptic area of the rams’ hypothalamus was 50 percent smaller in male-oriented rams as opposed to female oriented rams. A 1991 study of human brains of AIDS victims showed a similar hypothalamus size difference between gay and heterosexual men.

The sheep researchers postulate that low levels of aromatase hormones in the brain of a developing male sheep fetus may have kept the brain from fully masculinizing, leading to sexually male-oriented rams.

“This lends further support to the idea that homosexuality has biological underpinnings,” Charles Roselli, a professor of physiology and pharmacology, said in an interview with the Corvallis Gazette-Times.

Professor Stormshak believes that “understanding sexual drives and the continuum of sexual behavior could possibly help explain the scientific basis of sexual assault [and] put an end to assertions that homosexuality is a lifestyle choice.”

In the 18 months since Andrea Muizelaar was crowned winner of the reality TV series Canada’s Next Top Model, her life has been a complete whirlwind. From working in a dollar store in her hometown of Whitby, Ontario, to modeling haute couture in Toronto, she had reached her dream of becoming a true Top Model.

But at what cost? Unknown to casual television viewers, Muizelaar had been enveloped in the eating disorder anorexia nervosa, which inevitably became too much for her to bear. She gave up modeling and moved back to Whitby, where she sought treatment for her disorder, re-entered college, and now works at a bank. Where is she now? Happy and healthy, she says.

Recently Andrea Muizelaar sat down with Wikinews reporter Mike Halterman in a candid interview that stretched to nearly two hours, as she told all about her hopes and aspirations, her battle with anorexia, and just what really happened on Canada’s Next Top Model.

Nine months after announcing the interoperability between their instant messaging (IM) services, Internet rivals Microsoft and Yahoo! began limited public beta (pre-release) testing of the program. This enables users of the two services to communicate with each other using their existing IM client, Microsoft’s Windows Live Messenger (formerly MSN Messenger) and Yahoo! Messenger with Voice.

Users wishing to use the new feature can go to a special page on the service’s website, where they have to review and accept an agreement. After signing out and signing in again, the interoperability is enabled without downloading any new software.

The service is designed to allow users to see each others’ online presence, view personal status messages, share select emoticons, view offline messages and add new contacts from either service. However, more advanced features, like voice calls and shared folders are not interoperable between the two services.

The program is available internationally in more than 15 markets.

Chemotherapy is usually associated with a collection of side effects ranging from digestive problems to hair loss, but a study published this week in Human Reproduction demonstrated that female cancer patients may find they have something in common with much younger women in one specific area — their ovaries.

Scientists from the University of Edinburgh examined donated ovarian tissue from fourteen female cancer patients, most of whom had Hodgkin lymphoma, and compared it to tissue from healthy women. They found the samples from women who had been treated with a specific chemotherapeutic regimen known as ABVD not only contained greater numbers of dormant ova — egg cells — than those from women treated with harsher regimens but also more than samples from healthy women. ABVD is named for combining several drugs known as adriamycin, bleomycin, vinblastine, and dacarbazine.

These reproductive cells were not merely more plentiful in ABVD patients. They also appeared immature, “new” in the words of lead researcher Evelyn Telfer. This challenges the conventional belief that girls are born with all the ova they will ever have and the numbers can only go down as the cells are either used up by the reproductive cycle or succumb to damage or natural aging. However, further research is needed to confirm this. The study covered relatively few patients by scientific standards, and David Albertini of the Center for Human Reproduction in New York has suggested the cells may not actually be freshly grown. Instead, they may have always been there and were merely rendered more detectable by ABVD treatment.

The ability to grow new egg cells may have significant implications for women in Western societies, many of whom postpone childbearing to establish careers, sometimes into their late thirties or forties. However, Telfer warns against making use of these findings too soon: “There’s so much we don’t know about the ovary. We have to be very cautious about jumping to clinical applications.”

The experiments had been discussed earlier this year at the annual conference of the European Society of Human Reproduction and Embryology.
