I’ve used KnowInnovation’s Ideas Lab approaches to knowledge generation on several occasions both in and outside of government. Here, another approach is to have experts produce estimate unknowns (in this case future sea level rise) and then to do statistics on those estimates. Sort of like betting markets but without the money.
A fantastic paper just out about relating the cellular microenvironment to the R2t* component of the signal relaxation constant, here. The authors did two really clever things: first they related the signal from the brain microenvironment (think, the area around individual synapses) to the Default Mode Network–a signature of resting awake cognitive activity. Second, they used the Allen Gene Brain atlas to look at the interplay between this brain imaging signal and the gene networks that define the molecular biology of the nervous system.
Definitely an important result. All of this out of the outstanding group at Washington University St. Louis that has been pushing the limits in this field.
I am back from a week of vacation in California. My native state is as beautiful as ever. However, on the plane flight back to DC, we flew directly over Yosemite where the smoke from the wildfires was clearly visible and concentrated in the Valley. It’s a reminder of how powerful nature can be and how it’s not a given that it’ll be aligned with human concerns. The image below is from my visit to Yosemite last summer. There were fires then also.
This coming week, the new semester begins. I’m looking forward….
The news posted in Science, here. To my mind, he is a superb choice. Kudos to the White House. Kelvin was Vice Chair of the National Science Board during the first two years of my tenure leading BIO at NSF and I was always struck by his thoughtful way of working through really big challenges, while at the same time pushing everybody forward. He is a really fine atmospheric scientist and his credibility with the community will help him enormously.
If he is confirmed, the key question is whether he will have direct access to the President and further, what the quality of those interactions may be.
In Science, here.
I sympathize with many of his points, in particular about the value of scientists serving inside the US government. Unfortunately for many, including Joel, that has become impossible.
Here’s the story in Time Magazine. I took this photo of a similarly sized iceberg off Fogo in Newfoundland. The difference? The one in my photo is about 20 km from my camera. They are huge of course. As the ice breaks up in the Arctic, more of these will be moving south down the Chanel between Labrador and Greenland. How will that change the dynamics of the Atlantic Ocean? Well, there is this report by Rasmus Pedersen. Money quote:
These characteristics mean that sea ice loss initiates feedbacks that contribute directly to Arctic amplification of near-surface warming (Serreze et al. 2009; Screen and Simmonds 2010; Serreze and Barry 2011).
This an interesting new scientific meme. It made it into Science on the basis of a presentation at the International Conference on Machine Learning here. The idea is that hackers can easily defeat AI’s (think “social engineering” used on a machine).
Meanwhile there is the contrasting meme of us getting spoofed by AI, in the FT, here. In this case AI’s are able to make videos of people doing things that they did not do.
All of this gets to the cybersecurity aspects of AI that potentially put society at risk.
