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. Paleontology

    Telltale Dino Heart Hints at Warm Blood

    A recently discovered fossil dinosaur heart is more like the heart of birds and mammals than that of crocodiles, providing further evidence that dinosaurs may have been warm-blooded.

  2. Chemistry

    Sweet tooth is in the genes

    Taste researchers have narrowed the search for the sweet tooth gene, at least in mice, to a 100-gene region.

  3. Chemistry

    Birth control for male cockroaches

    Scientists have discovered a gene in German cockroaches that may lead to a new type of insect control—contraception for male cockroaches.

  4. Chemistry

    Coming up roses in scent research

    Aroma chemists have discovered a carotenoid-processing enzyme that makes the chemicals that give rose oil its smell.

  5. Earth

    It’s high tide for ice age climate change

    Tides may sometimes be strong enough to tug Earth into an ice age.

  6. Tech

    Coal: The cool fuel for future jets

    To power faster supersonic jets, scientists are developing coal-derived fuels that can absorb heat without breaking down at high temperatures.

  7. Paleontology

    Dinosaurs, party of six, meat eating

    The bones of six carnivorous dinosaurs discovered in a fossil bed in Patagonia may indicate that big, meat-eating dinosaurs were social creatures.

  8. Paleontology

    Fossil gets a leg up on snake family tree

    A 95-million-year-old fossil snake with legs may be an advanced big-mouthed snake, not a primitive ancestor.

  9. Earth

    Titanic iceberg sets sail from Antarctica

    An iceberg about the size of Connecticut recently split off from the Ross Ice Shelf in Antarctica.

  10. Earth

    Greenhouse Gassed

    Scientists are discovering that more carbon dioxide in the air could spell disaster for plants and the animals that love to eat them.

  11. Researchers enjoy bitter taste of success

    Scientists have identified a large family of proteins that work as taste receptors for bitterness.

  12. Earth

    Ice age forest spruces up ecology record

    Scientists have recently discovered a 10,000-year-old forest buried in the sand in Michigan.
