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.

All Stories by Tina Hesman Saey

  1. Life

    A protein called Six-Microns-Under turns certain fruit fly brain cells into undertakers to clear away dead neighbors.

  2. Health & Medicine

    Friend or foe? Drunk, the brain can’t tell

    Intoxicated brains can’t discern between threatening and safe situations.

  3. Health & Medicine

    Let there be light

    Researchers report restoring vision to people with a rare, genetic form of blindness. A different technique helped blind mice see again and could bring back some sight in people with macular degeneration, retinitis pigmentosa or other blinding diseases.

    Review by Tina Hesman Saey.

  5. Health & Medicine

    Asperger’s syndrome may not lead to lack of empathy

    People with high-functioning autism respond to others' pain, two studies show.

  6. Life

    Rest in peace nanobacteria, you were not alive after all

    New studies bid a fond farewell to nanobacteria -- the extremely tiny “microorganisms” that have sparked controversy and may cause disease.

    Body and Brain: Possible link between inflammation and bipolar disorder

    Inflammatory genes create a signature for bipolar disorder in some people.

  8. Foul Play: Genetics may affect athlete doping tests

    Athletes' genetic makeup may allow them to beat anti-doping tests.

  9. Dad’s Hidden Influence

    Fathers share more than genes with their children. Where a man works, the chemicals he is exposed to, and even his age can leave a medical legacy for future children.

  10. Alzheimer’s mystery protein unmasked

    A protein linked to Alzheimer's disease may help young people forget, too.

  11. Aging Factor: Gene mutations may be key to long life

    Some centenarians carry mutations in a pathway associated with longevity in worms and fruit flies.

  12. Health & Medicine

    Sun, inflammation speed aging of skin

    Gene profiles show inflammation is the key to making skin age, and sun exposure speeds the process.
