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.

    Imprisoning parasites can deter malaria’s spread

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

  3. Health & Medicine

    Cells in groups may promote cancer’s spread

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

  4. Life

    Softer surroundings stifle some chemotherapy drugs

    Some anticancer drugs such as Gleevec are less effective when attacking cancer cells grown in soft surroundings.

  5. Earth

    Mineralogy’s link to ecology makes an Earth twin unlikely

    Earth’s unique blend of minerals emerged with the evolution of life, making it extremely unlikely that another planet has Earth’s exact mineral composition.

  6. Archaeology

    In mice, viral infection can help intestines develop, strengthen immune system.

  9. Neuroscience

    Protein production prevents sleep-loss forgetfulness

    Boosting levels of certain proteins in mice prevented memory problems associated with sleep deprivation.

  10. Genetics
