Empty space is never actually truly empty.
Even a quantum field in its lowest-energy state, the vacuum, has unavoidable fluctuations that arise from the Heisenberg uncertainty principle: Certain pairs of properties cannot both have precisely defined values at the same time.
In real-world terms, this means that a quantum field should resemble a staticky TV, and plenty of indirect evidence suggests this is the case.
Researchers have found that an upstream promoter of two extracellular matrix proteins increases healing and strength capabilities in the tendons of rats.
Tendon injuries in older people
Previous research has found that, like with many other injuries, tendon injuries have an age-related component. The tendons of the biceps and rotator cuffs are more commonly injured in older people than in younger people [1], and older people heal slower after forearm injuries and have less range of motion in the fingers for a longer time [2].
Physics is most readily applied to relatively simple systems: a pendulum, two electrons colliding or the structure of the solar system. But when systems become complicated—when many particles interact with one another, in condensed matter systems such as gases and fluids or in the cosmology of the early universe—simplifications can be made using a technique called classical or extended mean-field theory.
A research group from Princeton University, led by lead author Luca Di Carlo, has applied extended mean-field theory to networks of biological neurons. Their work is published in the journal Physical Review Letters. They found that the simplest versions of mean-field theory failed to accurately describe the activity of these networks, but an enhanced version was able to do so.
John’s, Newfoundland, and told a room full of circus artists they were not entertainers.
They were context creators.
The argument goes like this. Content is now infinite. AI can produce more of it in a second than you could consume in a lifetime. So content is not king anymore. It is a commodity, and commodities get cheap.
What stays expensive is meaning. And meaning does not live inside the content. It lives in the frame around it.
Change the context, and you change the story. Change the story, and you change the future.
In this keynote, I make the case for #STEAM over #STEM, for why technology is the How and never the Why, and for why the circus tent is the most honest metaphor we have for the age of #AI: risk, awe, vulnerability, transformation, and a safety net that may or may not be there when you let go of the bar.
Chuck Brooks argues that cybersecurity has fully shifted from an IT function to a core business, governance, and fiduciary responsibility. In an era defined by AI, quantum computing, connected infrastructure, and expanding digital dependencies, cyber risk is now enterprise risk — directly tied to bu

Expanding humanity into outer space would represent one of the greatest transitions in human history. If millions of people eventually live and work in space, the social structures familiar to us today are likely to evolve into very different forms. Predicting those structures is difficult. Few, if any, could have predicted the profound societal transformation that occurred in Europe following the Industrial Revolution. The transition from extended families living within largely rural and feudal systems to nuclear families living in densely populated industrial cities and democratic states is now well studied, yet it would have been difficult to foresee before it occurred.
Similarly, when hunter-gatherer communities began settling permanently and developing agricultural villages, their social structures changed dramatically. We understand many aspects of this transformation today, but those living before the transition could hardly have predicted its consequences.
This article attempts to connect the consequences of large human populations living in space with the possible evolution of societies both on Earth and beyond it. One major consequence considered here is the possible abolition—or fundamental transformation—of the military institution, along with other highly hierarchical institutions.
