    Top 10 Women in Molecular Biology
    When you put the helmet on, it doesn't matter if you are woman or man: your mission is to compete to win. -- Milka Duno Below are notable women in STEM that have greatly impacted the scientific community with their efforts. These are the top 10 women in molecular biology. Rosalind Franklin Since the age of 15, Rosalind Franklin wanted...
  2. Cancer Treated by Purifying Proteins

    Cancer Treated by Purifying Proteins Protein purification is a series of processes intended to isolate a single type of protein from a complex mixture. Protein purification is vital for the characterization of the function, structure and interactions of the protein of interest. The starting material is usually a biological tissue or a microbial culture. The various steps in the purification...
  3. Cancer Research Using Blasticidin S

    Blasticidin S is an antibiotic used by scientists in bio-research to select cells modified by genetic engineering. It inhibits the growth of a wide range of prokaryotic and eukaryotic cells by interfering with protein synthesis. Blasticidin S allows the selection and maintenance of cells expressing the blasticidin-resistance gene.
  4. Innovator Tracks Everything His Body Does

    Larry Smarr stops a visitor and says, “Before you go, let me show you my stool sample.” The UC San Diego physicist-futurist reaches into his kitchen refrigerator, past the milk, and pulls out a small white box. He marvels over its contents. “The bacteria in here contains more info than you’d find on a computer chip,” Smarr says. “It’s a window into your health. Within 10 years, people won’t dream of going to a doctor without first getting a sample like this.” Feeling squeamish? Smarr can have that effect on people. Virtually nothing is out-of-bounds these days when he promotes the “Quantified Self,” an emerging movement in which people use biosensors and other gadgets to closely monitor their bodies in the name of wellness.
  5. Quinomycin A, HIF-1 Inhibitor

    Quinomycin A, also referred to as Echinomycin, is a peptide antibiotic which binds strongly to double-helical DNA up to a limit of approximately one molecule per five base-pairs. There is no detectable interaction with rRNA and only extremely feeble non-specific interaction with poly(rA) .poly(rU).
  6. Epigenetics reinforces theory that positive thinking heals

    There was a time where love and nurture seemed clearly distinct from our physical nature. Genetic-determinism holds that genes control our lives; hereditary information flows in one direction, and genetic activity and cellular expression are regulated by information from the DNA.
  7. Epigenetic 'Memory' Key to Nature Versus Nurture

    "There are quite a few examples that we now know of where the activity of genes can be affected in the long term by environmental factors. And in some cases the environment of an individual can actually affect the biology or physiology of their offspring but there is no change to the genome sequence."
