Regeneration as a biological phenomenon

I’m busy co-editing a virtual symposium issue of our journal, The Biological Bulletin on regeneration with my MBL colleague Joel Smith. For loyal readers unfamiliar with regeneration in the biological context, we are referring to the phenomenon whereby certain animals regenerate tissue (limbs and sometimes even brains) either in the natural course of their life cycle or in response to injury.

Regeneration was one of the main concentration areas of Bernie Agranoff’s laboratory at Michigan at the time when I was doing my thesis work under him. The lab model was the goldfish optic nerve, which in response to injury, can completely repair itself.

But that was a long time ago. What has been wonderful about the present virtual symposium as been re-familiarizing myself with a field, that is, if anything, more exciting and relevant today, that it was in the last century, when it was part of my daily science diet.

In particular, I’ve been enjoying reading the work of HHMI scientist Alejandro Alvarado. His work in the area is seminal and he has brought the full power of molecular and cellular biology to the question.

Biddy Martin comes to Amherst

My Alma Mater has successfully raided the University of Wisconsin’s flagship Madison campus to recruit its new President. The Chronicle’s link is here.

The connection between Madison and Amherst is not without precedent. Alexander Meiklejohn was President of Amherst College from 1913-1923, from which he decamped for Madison to start an experimental college at the University of Wisconsin. His successor at Amherst, was my great grandfather, George D. Olds.

Congratulations to Amherst College on a great recruitment.

Solar Power close to economic feasability?

At today’s Financial Times here. My colleague Tyler Cowen isn’t convinced and brings up a mismatch with another of today’s headlines at Marginal Revolution.

My sense is that over the long haul, solar power is the big Kahuna of renewables. But the key technological advance may be some ways in the future–if we can capture solar flux directly in space and the packetize it for delivery here on Earth.

In the meantime, the existing solar capture technologies are all intriguing, from artificial photosynthesis to better photovoltaics.

Gina Kolata’s interview with three top women scientists at NYT

The interview is here. Includes Joy Hirsch, fellow neuroscientist at Columbia University.

Money quote from Hirsch:

When I was at Yale, I was the chairman of the Status of Women Committee for a long period of time. During that time Yale as an institution had a major commitment to raise the visibility and the numbers of women, and we did exactly as you described without a compromise at all in quality. It is not that we just teach our women to be self-promoting and to be excellent. We must also, I think, take the responsibility of teaching our institutions to be receptive and proactive and even aggressive in this manner.
