    Safer creation of stem cells

    A new technique for converting adult cells to stem cells avoids dangerous mutations in cell DNA

  2. Life

    Nanoparticles: size and charge matter

    Nanoparticles can be designed for targeted delivery of drugs or genes into the body. New work reveals details of how blood proteins respond to these particles.

  3. Life

    FDA releases guidelines for genetically modified animals

    Draft rules lay out policies for approving altered animals, including those used for food.

  4. Physics

    A ‘novel’ chemistry to make fuel from sugar

    It’s not alchemy, but it might sound like it: a new way to transform sugars from plants into gasoline, diesel or even jet fuel by passing the sugars over exotic materials.

  5. Health & Medicine

    Good day care grime

    A study of 952 children in Manchester, England, suggests that children going to day care starting at age 6 months could be less likely to develop asthma later.

  6. Potent Promise: Back to the Womb

    Normal 0 false false false MicrosoftInternetExplorer4 Normal 0 false false false MicrosoftInternetExplorer4 RESET BUTTON Scientists are now able to “reset” the DNA in a mature body cell so that the cell can grow into any kind of cell in the body, from heart muscle cells to nerve cells and bladder cells.

  7. Life

    Live long and alter

    Yeast cells fed a calorie-restricted diet live longer and have just as much energy as those fed a normal diet.

    Finding health in fragility

    Normal 0 false false false MicrosoftInternetExplorer4 GOTHENBURG, Sweden —Woody Allen might have coined it: the law of conservation of fragility. If part of a biological network gets stronger, some other part is bound to get weaker, new research shows. Its total fragility never gets better or worse, it just stays the same. Rather than being a […]

    Stem cells, show your face

    As researchers develop ways of reprogramming adult cells, such as skin cells, to have the same flexibility as embryonic stem cells, this new test shows that the reprogrammed stem cells are truly capable of becoming any cell in the body.

  10. Earth

    Carbon caveat

    Adding carbon compounds to some ocean systems may lead to a counterintuitive drop in their overall carbon content — and how much carbon dioxide the ocean could store.

  11. Life

    Brain boost

    Protein improves old rats’ ability to form new memories.

  12. Health & Medicine

    Finding the golden genes

    Advances in gene therapy could tempt some athletes to enhance their genetic makeup, leading some researchers to work on detection methods just in case.
