New study: The longer a wild mammal is traded, the greater the risk is to public health.

Hybrids On The Horizon - bioGraphic Chance encounters and novel conditions have led to different species cross-breeding more often. Is it a good thing?

Scientists once held that the boundary between species was their ability to mate and make viable offspring. But hybrids, it turns out, are everywhere. Now, as geneticists gain insight into animals’ inner workings, they’re learning that the boundaries between species have always been porous.

Natural ecosystems spread risk across genes, species, space, time and strategy. Many human systems have optimised away such slack.
Here are some lessons from ecosystems for a world obsessed with efficiency.

I don't see this said enough: the widespread use of generative AI is not only making our jobs as educators harder logistically, but also emotionally. It is genuinely sad to be suspicious of students when you have spent so much time building a pedagogy based on trust and not being a cop. It sucks.

Motherhood derails women’s academic careers — these data reveal how and why Mothers in academia take on considerably more childcare-related responsibilities than do fathers.

Becoming a parent is much worse for women in academia vs men, because women do 5 times (!!!) the amount of childcare than men www.nature.com/articles/d41...

Whenever I hear about the leaky pipeline, I recall an interview I saw when I was an undergrad with a woman in STEM who said "I'm all for getting more women into the pipeline but people don't realize that the pipeline is full of acid."

NIH and other grant terminations exacerbate this situation.

The House of Representatives is set to pass H.R. 556, the so-called “Protecting Access for Hunters and Anglers Act".

This would prohibit the Departments of Interior and Agriculture from protecting human health, wildlife, and our environment from toxic #lead in ammunition and fishing tackle.

A photo of an elongated, matte-brown, prehistoric-looking Australian lungfish named Methuselah, resting on the sandy bottom of her tank at the Steinhart Aquarium in San Francisco. She has yellow patches near her small eyes. Several other much smaller Australian rainbow fish are also in the tank. She is probably in her 90s and has been at the aquarium since 1938.

This is Methuselah, an Australian lungfish whom I first met at the Steinhart Aquarium in 1976. She is probably in her 90s, and has been at the Steinhart since 1938. I love her.

The fundamental premise behind AI-enabled cheating is that coursework is merely busy work, because your'e just doing it for professors.

We would never say that showing up for football practice is merely busy work because you're just doing it for your coaches.
