nature was much more inventive
Space scientist Edward Stone served as project scientist for NASA’s Voyager missions for 50 years, as well as playing a major role in many other missions, acting as director of NASA’s Jet Propulsion Laboratory and running his own lab at Caltech. Stone has died, aged 88. Here are some remarkable quotes from “Celebrating Voyager’s 40…

Market forces are not enough to halt climate change
A very interesting opinion has been published a while ago in the FT: “Market forces are not enough to halt climate change“ I like to repeat the quote used in the “Nature Anthropocene briefing of July 5“, with following comments:The desire for financial returns will mean that fossil fuels continue to be good investments, thus…

Shifting attention
The Internal Dominance over External Attention (IDEA) hypothesis (I referred to earlier) asserts, contrary to the traditional view of attention as being primarily externally oriented, that attention is inherently biased toward internal information. A related work on attention switching has been published: “Shifting attention between perception and working memory“ Most everyday tasks require shifting the…

On principles of emergent organization
Adam Rupe, James P. Crutchfield published “On principles of emergent organization“: After more than a century of concerted effort, physics still lacks basic principles of spontaneous self-organization. To appreciate why, we first state the problem, outline historical approaches, and survey the present state of the physics of self-organization. This frames the particular challenges arising from mathematical intractability and…

energetic cost of allostasis and allostatic load – do not stress
Chronic psychosocial stress increases disease risk and mortality, but the underlying mechanisms remain largely unclear. This article in Psychoneuroendocrinology outlines an energy-based model for the transduction of chronic stress into disease over time. The energetic model of allostatic load (EMAL) emphasizes the energetic cost of allostasis and allostatic load, where the “load” is the additional…

Fast walkers have higher IQ and larger brains than slow walkers.
These findings are from a 5-decade cohort study of 904 participants in New Zealand published in @JAMANetworkOpen which tested the hypothesis that slow gait speed reflects accelerated biological aging at midlife. Slow gait was associated with multiple indices of compromised structural brain integrity, including smaller total brain volume, global cortical thinning, and reduced total surface…

Andy Clark “How the brain shapes reality”
Philosopher and cognitive scientist Andy Clark challenges our conventional understanding of the mind’s interaction with the world. A great and entertaining lecture. I like the reflection with the reference to the weather forecast and how the forecast impacts “reality” perception. At the very least, understanding all those prediction-driven, precision-inflected, looping influences should bring us a…

Why the simplest explanation isn’t always the best
Eva L. Dyer and Konrad Kording discuss in a commentary article “Why the simplest explanation isn’t always the best” an essential learning related to the article Phantom oscillations in principal component analysis (also available on BioRXiv) Dimensionality reduction simplifies high-dimensional data into a small number of representative patterns. One dimensionality reduction method, principal component analysis (PCA), often selects oscillatory…

42 and 5
Today, 42 years ago, we had the great pleasure of discovering the reality of 5-fold crystals. On the morning of 8 April 1982, an image counter to the laws of nature appeared in Dan Shechtman’s electron microscope. In all solid matter, atoms were believed to be packed inside crystals in symmetrical patterns that were repeated…
