Senior Writer, Molecular Biology, Science News

Science News 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 Endocrine Society, the Genetics Society of America and by journalism organizations.

    Should we use a genetic weapon against mosquitoes carrying malaria?

    One gene drive to eliminate malaria seems to work in the lab. Now it’s time to ask local people if they want it released in the wild.

  5. Animals

    If mosquitoes vanished, would we miss them? Vampire spiders might

    Vampire spiders get their meals from blood-filled Anopheles mosquitoes. But if those insects disappear, the spiders will likely adapt.

    Dogs and other animals could aid the spread of monkeypox

    Now that monkeypox has spread to a dog, researchers fear other species could help the virus become widespread outside of Africa for the first time.

    Explainer: What is mpox (formerly monkeypox)?

    Once rare, the viral disease monkeypox exploded onto the global scene for the first time in 2022.

  9. Health & Medicine

    To test for COVID-19, a dog’s nose can match a nose swab

    Dogs can sniff out COVID-19 cases as well as PCR tests can — and are better at ID’ing cases having no symptoms, a new study finds.
