Tina Hesman Saey

Senior Writer, Molecular Biology

Senior writer Tina Hesman Saey is a geneticist-turned-science writer who covers all things microscopic and a few too big to be viewed under a microscope. She is an honors graduate of the University of Nebraska-Lincoln where she did research on tobacco plants and ethanol-producing bacteria. She spent a year as a Fulbright scholar at the Georg-August University in Göttingen, Germany, studying microbiology and traveling.  Her work on how yeast turn on and off one gene earned her a Ph.D. in molecular genetics at Washington University in St. Louis. Tina then rounded out her degree collection with a master’s in science journalism from Boston University. She interned at the Dallas Morning News and Science News before returning to St. Louis to cover biotechnology, genetics and medical science for the St. Louis Post-Dispatch. After a seven year stint as a newspaper reporter, she returned to Science News. Her work has been honored by the National Academies of Sciences, Engineering and Medicine, the Endocrine Society, the Genetics Society of America and by journalism organizations.

    Insect-eating bats implicated as Ebola outbreak source

    Insect-eating bats, not fruit bats, may have started the Ebola epidemic.

  2. Life

    Contamination blamed in STAP stem cell debacle

    Stem cells supposedly made in acid baths were really embryonic stem cells, investigation finds.

  3. Genetics

    The art of DNA folding

    Cells must compress genetic material into a nucleus that measures only about 5 micrometers across. To accomplish the feat, cells make loops in the DNA.

  4. Life

    Hydrogen sulfide offers clue to how reducing calories lengthens lives

    Cutting calories boosts hydrogen sulfide production, which leads to more resilient cells and longer lives, a new study suggests.

  5. Life

    Bird flu follows avian flyways

    A deadly bird flu virus spreads along wildfowl migration routes in Asia.

  6. Genetics

    Evolve and Linkage turn science into games

    In the two new games Evolve and Linkage, biological principles are made entertaining and strategic.

  7. Humans

    Year in review: Old humans reveal secrets

    DNA of the oldest modern humans is rewriting the prehistories of Europe, Siberia and the Americas.

  8. Genetics

    Domestication did horses no genetic favors

    Horses bear the cost of domestication in the form of harmful genetic variants, a study of equine DNA finds.

  9. Genetics

    Year in review: Genes linked to tameness

    A look at the genes of domesticated animals offers possible insights into why taming has altered animals’ appearances.

  10. Genetics

    Year in review: Easy stem cells a no go

    An incredibly easy method for making stem cells turned out to be impossible, again tainting the stem cell research field with controversy.

  11. Life

    Imprisoning parasites can deter malaria’s spread

    Disabling a protein traps malaria-causing parasites within red blood cells and prevents the organisms from reproducing.

  12. Health & Medicine

    Cells in groups may promote cancer’s spread

    Cellular gangs, not individuals, form distant tumors from breast malignancies, a new study finds.
