      Frozen Embryos Make Bigger Babies

      (Newser) - When it comes to in vitro fertilization, frozen might be better than fresh, a new study shows. Infants born after being implanted in mothers' wombs as frozen embryos were no more likely than those from fresh stock to be born with congenital defects, the BBC reports; but they were also significantly heavier, and less likely to be born prematurely.

      Human-Animal Embryos Created

      (Newser) - In a brave new world breakthrough, British scientists for the first time have created animal-human hybrid embryos, the London Times reports. The nuclei of cow eggs were removed and replaced with ones from a human cell, creating "admixed" embryos—or "cybrids" whose genetic material is 99.9% human. Electricity jolted the cybrids to life and they survived for three days. The research team aims to create longer-living cybrids for use in stem cell research. More »

      And Baby Makes ... Too Many?

      (Newser) - Fertility doctors are beginning to wonder whether they're too successful. With in vitro fertilization prompting a 70% increase in the rate of multiple births since 1980, some are espousing a switch to single-embryo transfer. The procedure lowers the success rate but also lowers the rate of multiple births, with their attendant health risks, the New York Times reports. More »

    • UK Military Wives Freezing Husbands' Sperm

      UK Military Wives Freezing Husbands' Sperm

      (Newser) - More UK military wives are freezing their husbands' sperm before the men serve in the Middle East. One London fertility clinic expected interest from soldiers but was surprised by the "wives and girlfriends who want to have children should anything happen," a spokesman said. But servicemen must give consent before sperm storage, experts say, due to the high divorce rate among soldiers. More »

      Calif. Firm First to Clone Human Embryos

      (Newser) - A California lab has cloned a human embryo, a science first; the researchers stopped short, however, of creating stem cells. Using a process called somatic cell nuclear transfer, the scientists fused DNA from a man’s skin cells with donated egg cells—and created an embryo with cells specific to the man. Scientists hope stem cells could replace damaged cells with reduced risk of rejection. More »

      Stem Cells Made Without Destroying Embryos

      (Newser) - Scientists have created new embryonic stem cells while keeping the donor embryos intact, Wired reports, a breakthrough that could finally permit long-delayed research into curing cancer, heart disease, and Alzheimer’s. Researchers plucked single cells from 2-day-old human embryos, coaxed them to become ESCs, and developed them into heart tissue, neurons, cartilage, and blood cells. More »

      Abortion Foes' New Strategy: Personhood for Embryos

      (Newser) - Tired of waiting for a more right-leaning court to revisit Roe v. Wade, opponents of abortion in several states are adopting a new strategy: constitutional amendments to grant human status to embryos. The LA Times reports on a grass-roots movement to put referendums on state ballots: It faces considerable obstacles but has pro-choice advocates nervous. More »

      Stem Cell Breakthrough Spares Embryos

      (Newser) - Normal skin cells can be transformed into the equivalent of stem cells in mice, researchers report, and the new technique may revolutionize research on humans. Because it doesn't involve embryos or eggs, the process skirts the ethical quagmires surrounding human stem cell research; the easy availability of raw material and relative simplicity of the technique are logistical pluses.
