1. Forever chemicals are building up across the Great Lakes food web

    The research was conducted by a team at the University of Notre Dame led by Gary Lamberti and Daniele De Almeida Miranda. “Unfortunately, the Great Lakes hold onto their water and contaminants for a very long time, meaning that there’s ample time for toxins to be taken up by the biota,” Lamberti said.

  2. US’s Screwworm Fix Is Still a Year Away, Risking More Spread

    Without intervention, a female fly could lay more than 3,000 eggs over a lifespan of two to four weeks, according to Lee Haines, associate research professor of biological sciences at the University of Notre Dame.

  3. From neon mosquitoes to winged migrations, top images captured by scientists

    "It looks like I'm traveling through space, doesn't it?" asks Lee Haines, a vector biologist at the University of Notre Dame and the person peering into the microscope in the image. "I am looking at a mosquito that has taken a sugar meal that has been spiked with a drug," she says.

    Shayanta Chowdhury, the photographer and a physical chemist at the University of Notre Dame, was pleased to see his image elevating Haines' science. "Some people think scientists are in their ivory towers doing their own research and it doesn't really benefit or impact society as much," he says. "But I think it does and being able to use art to showcase that in science is powerful."

  4. Five winning images of scientists at work

    Under ultraviolet light, the yellow fever mosquito (Aedes aegypti) in Lee Haines’s microscope glows bright: a sign that it has fed on a sugar concoction spiked with a fluorescent dye and a mosquito-killing agent. Haines, an entomologist at the University of Notre Dame in Indiana, is part of a team studying how the drug nitisinone can be used to kill blood-feeding insects. 

    “The UV illumination created striking colours from both the tiny mosquito and the condensation that formed beneath the cold Petri dish,” says photographer Shayanta Chowdhury. As a chemistry PhD student at Notre Dame, Chowdhury uses lasers and spectrometers to study molecules attached to nanoparticles.

  5. What to know about the New World screwworm fly and its reappearance in the US

    Livestock are vulnerable because of how they’re handled, Lee Haines, an associate research professor of biological sciences at the University of Notre Dame, said in an email Thursday. Standard practices with cattle can break the skin, including shearing and de-horning, or even moving them in and out of corrals can cause scrapes and cuts. Birth would also make a mother and calf vulnerable, she said.

  6. US screwworm case puts ranchers on alert, rallies cattle prices

    The infestation signals screwworm flies arrived in the U.S. anyway and will expand ​in wildlife populations, said Lee Haines, an associate research professor of biological sciences at the University of Notre Dame in Indiana. "The burden falls hardest on farmers who must ​monitor animals scattered across vast open rangeland, often going unobserved for days at a time," Haines said.

  7. Tribal Council in the Lecture Hall: Why Higher Ed Loves ‘Survivor’

    As the reality TV series reaches the finale of its 50th season, Inside Higher Ed spoke to more than half a dozen faculty contestants about what drew them to the show and how they’ve incorporated their fandom into their classes.

  8. This tick season, make friends with permethrin

    Permethrin is a "life-saving" chemical compound that protects against contracting deadly detector-borne diseases, said Lee Haines, an entomologist at the University of Notre Dame.

  9. Waterproof Gear Relied on PFAS. Not Anymore. Here's What to Know.

    Firefighting gear has “significantly more PFAS than a plain Gore-Tex jacket,” said Graham Peaslee, a physics professor at the University of Notre Dame who co-authored a study on firefighter textiles and PFAS.

  10. ‘Inside-out’ planetary system perplexes astronomers

    “The team that conducted this work consists of experts at the top of the field, and they have done a very fine job with the data,” says Lauren Weiss, an astrophysicist at the University of Notre Dame, who was not involved in the study. “As for their conclusion that LHS 1903 e formed in a gas-depleted environment, I would have liked to see a more detailed experiment exploring the giant-impact scenario,” she adds.

  11. Chemical pesticides can significantly shorten the lifespan of fish

    According to research led by Jason Rohr, a biologist at the University of Notre Dame in Indiana, even low levels of chemical pesticides can shorten the long-term lifespan of fish.

  12. Pesticide exposure linked to accelerated aging in fish

    The study, led by University of Notre Dame biologist Jason Rohr, ties real-world patterns in wild fish populations to controlled lab experiments designed to pin down cause and effect. 

  13. In fish, low doses of common pesticide speed aging and death

    Study co-author Jason Rohr, an environmental health scientist at the University of Notre Dame, says it’s too soon for regulators to make changes based on the team’s findings, but he hopes they will stimulate more research on chronic effects of chlorpyrifos and other pollutants. 

  14. Pesticides may drastically shorten fish lifespans, study finds

    Even low levels of common agricultural pesticides can stunt the long-term lifespan of fish, according to research led by Jason Rohr, a biologist at the University of Notre Dame in Indiana.

  15. Fake or faulty chemo threatens cancer care in Africa

    Marya Lieberman, the study’s co-author and a professor of cancer research from University of Notre Dame, US joined colleagues from Ethiopia, Kenya, Malawi, and Cameroon to conduct covert and overt sampling of seven frontline chemotherapies in their countries.

  16. Bad drugs or no drugs: Cancer patients face scary reality tied to foreign supply chain

    Marya Lieberman's team at the University of Notre Dame tested more than 180 samples of chemotherapy drugs, mostly from India, but shipped to more than 100 countries, including the U.S.

  17. Kate the Chemist hosts free science exploration series finale at Notre Dame

    One year ago, Kate the Chemist went from teaching science to the world on major talk shows in America to making history as the nation's very first professor for the public understanding of science at Notre Dame.

  19. Birds Near US Military Bases Have Higher Levels of PFAS, Study Finds

    PFOS is also "very bio-accumulative in biota," Graham Peaslee, a professor of physics at the University of Notre Dame, Indiana, told Newsweek, explaining that the chemicals will bioaccumulate in the insects, worms and larvae that the birds eat, and then in the birds too.

  20. A red meat allergy from tick bites is spreading – and the lone star tick isn’t the only alpha-gal carrier to worry about

    This delayed allergic reaction is called alpha-gal syndrome. While it’s commonly called the “red meat allergy,” that nickname is misleading, because alpha-gal syndrome can cause strong reactions to many products, beyond just red meat.
