    Pretty amazing.

    The research is at an early stage, but scientists suspect that the converted skin cells might have grown into mature sperm cells if they had been transplanted into the infertile men’s testes.

    If further work confirms the suspicion, it may be possible to restore male fertility by taking men’s skin cells, turning them into stem cells, and injecting these into their testes. The same might be done for men who are left infertile after having chemotherapy for cancer.

    So um, would you really care if the sperm of said sexy, muscled clone were viable? ;)

    MuchMoreThanMuscle saidWith the billions of people already here raping and pillaging the planet, can't we just let Mother Nature do her thing by working in ways to help create balance, preventing further overpopulation of our poor planet?

    If these guys shooting blanks want a child so badly let them adopt.


    Those who preach overpopulation are too often a few steps away from steps like forcing women to take depo provera in the developing world as has happened.

    "The World's Resources Aren't Running Out" - written by an environmentalist turned economist
    http://online.wsj.com/news/articles/SB10001424052702304279904579517862612287156?

    n 1972, the ecologist Paul Ehrlich of Stanford University came up with a simple formula called IPAT, which stated that the impact of humankind was equal to population multiplied by affluence multiplied again by technology. In other words, the damage done to Earth increases the more people there are, the richer they get and the more technology they have.

    Many ecologists still subscribe to this doctrine, which has attained the status of holy writ in ecology. But the past 40 years haven't been kind to it. In many respects, greater affluence and new technology have led to less human impact on the planet, not more. Richer people with new technologies tend not to collect firewood and bushmeat from natural forests; instead, they use electricity and farmed chicken—both of which need much less land. In 2006, Mr. Ausubel calculated that no country with a GDP per head greater than $4,600 has a falling stock of forest (in density as well as in acreage).

    Haiti is 98% deforested and literally brown on satellite images, compared with its green, well-forested neighbor, the Dominican Republic. The difference stems from Haiti's poverty, which causes it to rely on charcoal for domestic and industrial energy, whereas the Dominican Republic is wealthy enough to use fossil fuels, subsidizing propane gas for cooking fuel specifically so that people won't cut down forests.

    Part of the problem is that the word "consumption" means different things to the two tribes. Ecologists use it to mean "the act of using up a resource"; economists mean "the purchase of goods and services by the public" (both definitions taken from the Oxford dictionary).

    But in what sense is water, tellurium or phosphorus "used up" when products made with them are bought by the public? They still exist in the objects themselves or in the environment. Water returns to the environment through sewage and can be reused. Phosphorus gets recycled through compost. Tellurium is in solar panels, which can be recycled. As the economist Thomas Sowell wrote in his 1980 book "Knowledge and Decisions," "Although we speak loosely of 'production,' man neither creates nor destroys matter, but only transforms it."

    Given that innovation—or "niche construction"—causes ever more productivity, how do ecologists justify the claim that we are already overdrawn at the planetary bank and would need at least another planet to sustain the lifestyles of 10 billion people at U.S. standards of living?

    the key words here are "believe in".

    I whole hardly wish junk science discussions would not reference personal belief systems. Cite your personal beliefs but this means less than nothing to the next guy.

    This also falls in line with how so many people don't believe in global warming. I won't mention them so as not to turn this thread into a political one but not acknowledging our impact on the planet is blatant.

    To ignore the ever increasing landfills, garbage that winds up in our oceans to the point of changing genders of aquatic/marine life and the exhaustion of fuels is simply blatant.


    I'm not saying that humans don't have an impact on the earth. Quite clearly and obviously we do. The question is whether or not "overpopulation" is an issue. The data suggests it is not. In fact, even the UN is forecasting that within our lifetimes, we will begin to see population decline given birth rates fall (dramatically) as countries develop economically.

    It's time for my weekly trolling.

    You, riddler78, are a closed-minded, small-minded, head-in-the-sand jerk.

    You think fracking is great, that global climate change is a joke, that human beings are infallible ... in reality, we've not advanced because of minds like yours. The Earth is dying because of minds like yours.

    I wish I could empathize with you, but I fear I'd lose IQ points if I dropped to your level.

    Have a sunny, warm weekend, sweetheart.

    Mother Nature is doing her job: she gave humans brains and they're using them. There is more than enough room on this planet for this process, which is not going to cause mass overpopulation and environmental crisis hyperbolic rumors to the contrary.

    You apparently have no concept of supply and demand and how it negatively impacts our environment.


    I think he meant there *should* be more than enough room..
