The @uofguelph.bsky.social is planning a massive housing project to be built on natural land rather than more appropriate spaces for needed expansion

Where are environmental impact statements?
Where is the community engagement?

🐸 Frogs and false signals

A new study finds that grey treefrogs use daylight length to trigger 'antifreeze' buildup for winter. But as climate change warms winters, this cue may mislead them into preparing too early or too late.

On the day the #Nobel prize in #Chemistry is awarded, I offer this story of kindness and mentoring I received early in my career from an eventual Nobel laureate, Dr. #AzizSancar.

"A Nobel prize and the unknown benefits that come from saying yes"

A Nobel prize and the unknown benefits that come from saying yes
Aziz Sancar delivering his Nobel Lecture for his prize in Chemistry 2015. He said yes.
My early morning wakeup on Wednesday, October 7, 2015 began as usual with a, though admittedly not healthy, quick Twitter check. My internet-induced squint widened when I saw that Aziz Sancar was trending. Dr. Sancar had just been named co-winner of the Nobel prize in chemistry for his work on DNA repair mechanisms. Not at all surprised by the recognition of his career achievements, I was, however, flabbergasted because I actually know Aziz Sancar and in no small way, my career is what it is because of his generosity and kindness.
Twenty years ago, I was an MSc candidate studying the physiological ecology of amphibians at Trent University. At the time I was working with Michael Berrill on replicating and testing the findings of a 1994 PNAS paper by Andrew Blaustein and company. This was important work on declining amphibian populations in the Cascade Mountains. They found that these declining populations were characterised by low levels of a DNA repair enzyme called photolyase. This finding was intriguing because photolyase catalyses the repair of the principal form of damage to DNA from ultraviolet-b radiation. Because emerging ozone holes would result in natural populations experiencing an increased amount of UVB radiation, low levels of photolyase might be a “magic bullet” that explained which populations would be in decline in otherwise “pristine” areas.
Intriguing, but I was actually not ready to test it. With a potent combination of naïve enthusiasm, I figured I could simply contact the authors of the paper and ask them to teach me the methods that I needed to know to further their work. I tried email but could not find an address on the department website. So I phoned the Department of Biochemistry at the University of North Carolina at Chapel Hill. They explained that Dr. Sancar did not want or have an email address. I asked that the call be connected to his office. When he picked up the phone, I leapt immediately into my explanation that I was an MSc student from Trent University in Peterborough, Canada, and that I was hoping to visit his lab to learn methods of photolyase extraction that I would apply to my system. To my now weathered academic amazement, but, at the time, only to my joy, immediately and without hesitation, he said yes. If I could get myself to Chapel Hill, he would teach me what I needed to know.

So on my spring break of 1997, I rented a car (two cars actually – one died, another story) and drove from snowy Peterpatch to the flowering springtime of Chapel Hill, North Carolina to spend a week in Dr. Sancar’s lab. “Lab” didn’t quite cover it. Dr.’s Sancar (he and his wife, Dr. Gwendolyn Sancar) had a floor of the building at UNC. Dr. Sancar met me on that Monday morning and arranged for a postdoc and a PhD student to help me all week and ensure that I could extract and purify the enzyme. & so, fast forward 20 years when I wake 2 read that the world has recognised Aziz Sancar for his pioneering work in the broad field of DNA repair. It made me think about the often unappreciated or unintended effects that saying yes can have on those around you.
At the end of his Nobel Lecture in Sweden in December 2015, Dr. Sancar showed a slide acknowledging his lab and colleagues. In part, these people & their output are the metrics that the Nobel committee evaluated in awarding him the prize. It was an impressive, but I knew not an exhaustive, list, for Dr. Sancar’s direct effect on my career – & indirectly then on all the students I have worked with in the subsequent years – was invisible to the Nobel committee (and perhaps not even remembered by Dr. Sancar). But these effects are significant and they came from a busy scientist saying yes when confronted with a naïve but enthusiastic student. There were many reasons for him to not take my call, not encourage me to come to North Carolina, not host me while I was there nor mentor me through the review process later on. But he did. He did say yes and it had an immeasurable effect.
I now work with insects in the neotropics and Canada on questions of biodiversity. I don’t work with photolyase and I don’t work as a physiological ecologist. However, by saying yes to me 20 years ago, Dr. Sancar’s act of generosity enabled me to follow this path. In the over-scheduled and busy lifestyle that we lead, it is important to consider this ripple that saying yes can have. There are many intended and measurable outcomes of supervision and mentoring – however there are many, perhaps more, unintended and important effects that kindness can have. As Anne Galloway said on Twitter, “We’re all smart – distinguish yourself by being kind”. The Nobel committee unaware of the affect that he has had in other scientific disciplines through his generosity and kindness.
 
I don’t think I said it clearly enough before. Thank you Dr. Sancar.

I just received an email from my employer recommending that we 'participate with purpose' for our well-being.

You mean, work more?
Really?

I don't need to work more. I need more Teaching Assistants, smaller class sizes, and more administrative support.

As a primatologist, Jane Goodall was a huge inspiration to me. I admired the way she describes chimpanzee behavior with such detail and empathy, and she’s inspired so many people and advocated for chimpanzee conservation and welfare.

However, I'm dismayed at what her narrative leaves out (1/10)

Having an assignment for an undergrad class where students have to read press releases and their associated papers, and evaluate the difference in quality of information between the two really has highlighted for me how often various organizations purge old press releases & popular science articles

"Deep-sea mining threatens the ocean floor before we even understand what lives there"

Africa is leading the way on protecting the ocean. Now the world must follow
The high sea waters off West Africa may seem remote to people reading this in London or New York. But these waters can impact the very weather patterns that determine whether crops grow in British fields or storms crash into the eastern seaboard of the U.S. They provide oxygen for every breath we take.

I am begging Canadians to understand that Canada Post, like public transit, should not be a business - it's a service.

Canada Post is a lifeline for rural, remote and Northern communities and overall, we need to re-evaluate why people think they "need" random shit delivered ASAP.

The government is reducing service standards and Canada Post’s biggest advantage: its nationwide network.

This plan is about cutting back the postal service instead of investing to give it new revenue tools through things like postal banking. It’s shameful.

Hey, so...Covid rates have gotten real high. Maybe change your behavior to fit this new risk profile? Stop eating indoors at restaurants, mask on mass transit, that kind of thing?
A graph of Covid rates. It's more complex than can be described here, but the important bit is that the rates have gone up a lot since late July, nearly to the heights of last winter.
