How small is “small?” Spider silk nanofibrils are just a few molecular layers thick, equivalent to approximately one ten-thousandth the diameter of a human hair. They’re invisible to the naked eye and cannot be seen under an ordinary microscope.
Sabine Hossenfelder is a very popular science communicator who focuses largely on topics in physics. Although much of her content is effective and without issue, there is an undercurrent of anti-establishment rhetoric that has grown immensely as of late, and it is an enormous problem. Sabine is a not a charlatan like most of my other targets, and this is not a hit piece, but rather commentary on this aspect of her work and how it came to be. If you are a fan of hers, consider this perspective.

On this day in 1992, the Vatican admitted that Galileo was correct in believing that the earth went around the sun.
2. In the first place, I wish to congratulate the Pontifical Academy of Sciences for having chosen to deal, in its plenary session, with a problem of great importance and great relevance today: the problem of ‘the emergence of complexity in mathematics, physics, chemistry and biology’
The emergence of the subject of complexity probably marks in the history of the natural sciences a stage as important as the stage which bears relation to the name of Galileo, when a univocal model of order seemed to be obvious. Complexity indicates precisely that, in order to account for the rich variety of reality, we must have recourse to a number of different models.
Effective thermal management is essential to ensuring the performance and lifespan of modern electronics. While polymers are widely used in electronic components, they inherently exhibit poor thermal conductivity, limiting their effectiveness in dissipating heat. To overcome this, researchers have been investigating the potential of integrating highly conductive fillers, such as liquid metals (LM), into polymers.
A new computer vision system inspired by cats’ eyes could enable robots to see the world around them more accurately than ever before.
Robots, drones, self-driving cars and other autonomous systems are becoming more common, but they still struggle to see well in all environments and conditions. For example, self-driving cars perform poorly in rain or fog because these conditions affect the car’s sensors and cameras.
Coverage of the NASA/SpaceX Crew-9 Dragon Relocation from the forward port of the Harmony module at the International Space Station to the zenith port (Hague, Gorbunov, Williams, Wilmore; undocking scheduled at 6:35 a.m. EST, redocking scheduled at 7:18 a.m. EST)
NASA reconnected with Voyager 1, 15 billion miles away, after a sudden shutdown. Engineers face challenges maintaining this 47-year-old spacecraft’s interstellar mission.

Anirban Datta, Head of Discovery Biology at Verseon International Corporation, details how recent breakthroughs are bringing once-distant possibilities, such as testing drugs more efficiently and restoring lost organ function through implantation, closer to reality.
Imagine being able to create an in vitro replica of a diseased organ to study the molecular mechanism underlying the illness. Now take a step further: envision testing drugs in these organoids to identify the ones that can treat disease safely and effectively without needing to run expensive clinical trials first. Further still, think about implanting these mini organs into the patient to restore lost function. With multiple breakthroughs in recent decades, these goals are now much closer to reality.
The feathery gilled pink salamanders stop aging early and can regenerate their limbs. Studying them could be the next step in the journey to unlocking effective anti-aging treatments in humans.
