  1. Science Does Something Useful, Sort of Cures Baldness

    Hey, buddy? They have stem cells for that.

    Gentleman, I feel for you. When you lose your hair, society wants you to think that your virility and health are rapidly fading and soon you'll be a specter at death's door. Thankfully, science may finally have done what creams, pills, implants and prayers have not been able to, and discovered a cure for hair loss.

  2. Scientists Figured out How to Make Stem Cells From Regular Cells With Acid

    So stem cells are just regular cells on acid. Am I doing it right?

    Stem cells have amazing implications for medicine and genetics, but they've been bogged down for a long time in ethical debates and difficult cultivation procedures. That may all end with a new technique for creating stem cells by dipping any old cell in acid, which is way better than if dipping them in acid created a bunch of microscopic Two-Faces.

  3. Sperm Are Perfect and One Day They May Save Your Life, Say Creators of Spermbots

    Sperm brought you into this world, and sperm will keep you here.

    Though we may sometimes curse the speed of sperm (sorry Mom, Dad), tiny bio-bots that mimic the flagellar movement of natures' lil' swimmers and are powered by the contractions of heart cells may be the next step in fighting cancer and other common illnesses. In other words, when our heart and sperm work together as one, we ill be unstoppable.

  4. Human Liver Buds Successfully Grown From Stem Cells

    The liver buds continue to grow in mouse transplant subjects, suggesting they could one day help to save human lives.

    Researchers at Japan's Yokohama City University have reported in Nature this week that they have used stem cells to create human liver buds that continue to grow and perform the organ's normal functions when transplanted into mice. In experiments, the lab-grown liver-ettes even helped to stave off death in mice suffering from liver failure. Though a preliminary step that may not see practical application for years, this represents a major discovery that shows promise for growing human organs from scratch for use in organ transplants.

  5. Stem Cells Made From Cloned Human Embryos for the First Time

    In a scientific first, researchers at Oregon Health & Science University have created cloned human embryos they can use to harvest embryonic stem cells for human transplant. The long-sought advance -- which has the potential to make stem cell therapies safer and less prone to rejection -- has been the goal of many stem cell researchers for years, and will no doubt prove controversial, but could have the capability to drive the next stage of development in human stem cell therapies that could one day prove capable of of treating a vast range of diseases.

  6. Epilepsy in Mice Cured By An Injection of Fresh Brain Cells

    A team at the University of California San Francisco (UCSF) has seemingly cured epileptic seizures in mice suffering from the disease by injecting a dose of specialized cells directly into their brains. The work could pave the way for similar cell therapy procedures to one day treat the same disease in humans.

  7. Stem Cells Used To Grow Functioning, Implantable Thyroid Gland

    Researchers at the Free University of Belgium have unveiled what could be the new cool thing in the growing field of regenerative medicine -- an implantable thyroid gland grown from stem cells. The thyroid, implanted in a mouse test subject for trials, even produced hormones as it was meant to, which is important because, well, it's most of what the thyroid does, and if a replacement doesn't do that, it's not a very good replacement. But this one does, and may be, respectively, which is super cool in an abstract sense and even more so if you're a family member of on of the millions of people affected by poorly functioning thyroid gland.

  8. Artificial Eggs and Artificial Sperm Produce Real, Adorable Baby Mice

    The oft-asked question "How is babby formed?" just got a little more complicated to answer. A team of Japanese researchers have reared baby mice who are the product of joining an artificial sperm cell and an artificial egg. Both of the reproductive cells in question were made by transforming adult cells into induced pluripotent stem cells (iPSCs), the lab created stem cell strains that have shown both promise and peril in recent studies. Those iPSCs were then turned into sperm and egg cells, respectively, and finally turned into adorable mouse pups.

  9. Turning Adult Cells Into Stem Cells Is Eerily Similar to Turning Them Into Cancer Cells

    Today in Bad News: Stem cell research could have hit a sizable stumbling block today as researchers at the University of California - Davis released a study demonstrating similarities between laboratory processes that turn adult cells into induced pluripotent stem cells (iPSCs) and natural processes that turn cells cancerous. The troubling research adds to a growing body of evidence that iPSCs, while promising, are not ready for primetime. The silver lining though, is that understanding what's wrong with iPSCs today is the first step towards fixing it tomorrow.

  10. Key Difference Between Embryonic and Induced Stem Cells Discovered, Could Make Treatments Safer

    While there's maybe no medical technology today with more potential, stem cell treatments are not without their own problems. Induced pluripotent stem cells (iPSCs) -- those created in a laboratory after being devolved from other adult cells -- are getting easier to make every day, but are still expensive to manufacture and run the risk of causing health problems of their own, possibly even becoming cancerous. Embryonic stem cells (ESCs), meanwhile, have been shown to be effective and largely safe for patients, but their use in medicine remains controversial. A team of researchers working at the Salk Institute and the University of California San Diego has taken a step toward understanding what makes both sorts of cells tick, though. They've discovered a unique molecular signature that indicates when a stem cell has been created in a lab rather than harvested from an unimplanted embryo.
