This could be a nice activity for high school STEM classes and motivated teens.  More detail here.

 

musk and animal testing..

Neuralink appears to have a grim record.

...

current and former Neuralink employees say the number of animal deaths is higher than it needs to be for reasons related to Musk’s demands to speed research. Through company discussions and documents spanning several years, along with employee interviews, Reuters identified four experiments involving 86 pigs and two monkeys that were marred in recent years by human errors. The mistakes weakened the experiments’ research value and required the tests to be repeated, leading to more animals being killed, three of the current and former staffers said. The three people attributed the mistakes to a lack of preparation by a testing staff working in a pressure-cooker environment.

a sacred etruscan pool

A major archeological find.

...

Over a period of a few weeks in September and October, a team of archaeologists unearthed two dozen bronze statues of human figures, more than 2,000 years old and perfectly preserved in the hot mud and waters of an ancient, sacred pool.

The site is the hot springs of the Tuscan town of San Casciano dei Bagni — San Casciano of the Baths, one of many picturesque hilltop towns towering over lush green valleys dotted with majestic cypress trees.

mrna or the protein it codes for ..

Which is bigger?

...

The role of mRNAs as epitomized in the central dogma is one of fleeting messages for the creation of the main movers and shakers of the cell, namely, the proteins that drive cellular life. Words like these can conjure a mental picture in which an mRNA is thought of as a small blueprint for the creation of a much larger protein machine. In reality, the scales are exactly the opposite of what most people would guess.

The site has a number of interesting entries.

 

 

origami-like wings

High-speed video of earwig flight and wings.  The way they fold is fascinating  Around the 45 second mark you see how they fold to stow. Probably lessons for engineering.

the title is a bit click-baity

But the article is excellent.

The experiment can be seen as evidence for the holographic principle, a sweeping hypothesis about how the two pillars of fundamental physics, quantum mechanics and general relativity, fit together. Physicists have strived since the 1930s to reconcile these disjointed theories — one, a rulebook for atoms and subatomic particles, the other, Einstein’s description of how matter and energy warp the space-time fabric, generating gravity. The holographic principle, ascendant since the 1990s, posits a mathematical equivalence or “duality” between the two frameworks. It says the bendy space-time continuum described by general relativity is really a quantum system of particles in disguise. Space-time and gravity emerge from quantum effects much as a 3D hologram projects out of a 2D pattern.

another look at the pillars of creation

A beautiful and revealing combination of images from two of the cameras on the JWST

 Be sure and look at the detail in one of the larger images - the smaller 2000x 1872 png should be enough,  It should be noted that the images are in the infrared with colors we can relate to being assigned by an artist. 

 

 

starting and stopping

How athletes in sports like tennis and volleyball manage to accelerate and come to sudden controlled stops has been an unsolved problem.. now some progress .. we use calculus.

Physical Intelligence by Scott Grafton is a fun read on the neurology of physical movement.  Highly recommended.
