A couple of weeks ago, I was looking for some sort of newsy tidbit about circadian rhythms—the daily cycles that drive much of the physiology and behavior of living things—to share with my class of undergraduate students. My pick was a recent opinion piece by Kevin Gaston—an ecologist and conservation biologist in the UK—called "Lighting … Continue reading Goodnight, night lights?
It's been a while since my last blog post. I've had a busy month: launching a new semester with students, learning about a new sport with one of my kids, enjoying the last of the warm days outdoors, finding some local apples... and discovering the world of competitive baking on TV. But I've kept my … Continue reading When plants make headlines
Insect adventures A couple of days ago, my son spotted an insect riding along on our car's windshield shortly after I had started driving. A very pretty green grasshopper had found its way aboard while I was parked near some grass and trees. I hoped it would be alarmed enough by the wind to jump … Continue reading Insects of summer
In one of my very first blog posts on this site ("Raindrops keep falling on our heads…and on the microbes") I shared some science news I had seen about microorganisms and clouds. Scientists across different disciplines are trying to learn about the relationship between the planet's water cycles and the growth of tiny organisms (such … Continue reading Tiny science update: Clouds and microbes
Over the past week or so, I saw headline after headline reporting on extremes: heat waves in the Arctic, in England, in Japan. Wildfires in California and across Europe, including the Arctic circle. Drought in Australia. Extreme summer weather conditions around the world have suddenly become high-profile news, and none of it is encouraging. It made … Continue reading Climate and weather: Is this the new normal?
Did you see the news recently about the whale that died in Thailand because it had a stomach full of plastic bags and other trash—more than 17 pounds' worth? How about about increasingly vocal efforts to remove plastic drinking straws from the list of common dining accessories? Plastic news really caught my eye that past couple … Continue reading The perils of plastic
Did you hear the news? If you've got romaine lettuce on hand in the United States, and you don't know where it came from (such as a local farm), you are being urged by the Centers for Disease Control (CDC) to throw it out. A batch of romaine lettuce from Yuma, Arizona has been contaminated … Continue reading The under-appreciated lives of plants
I wanted to share a quick post about a book I finished reading this week, The Death and Life of the Great Lakes. In 2017, Milwaukee journalist Dan Egan wrote a compelling "un-natural history" of the Great Lakes, chronicling the shifting relationship modern human society has built with these giant inland seas. Balancing stories of … Continue reading From canals to carp–a book about the Great Lakes
Sparrows in the news? The little brown birds that visit my yard, that I never can confidently conclude are sparrows and not perhaps wrens? Yep. These unassuming neighbors have been featured in a few science headlines over the past couple of weeks, which I thought was curious. So I thought I'd pop in this week … Continue reading Sparrows in the news (yes, really)
We're almost midway through the semester at my university. It's a busy time for students and professors alike: assignments, exams, and projects seem to pile up... and so we all anticipate a few days of welcome respite during the upcoming fall break. Meanwhile, the days shorten, the leaves fall, the insects quiet down, and festive … Continue reading The rhythms of life–biological clocks and a new season
