3D printing in space

The European Space Agency sent along a 3D printer to the International Space Station, and recently, it was used to create a 3D metal object. As you might expect, in micro gravity, it took a while to calibrate the machines.

But the result is that they now can now print a part that they need for a repair on the station - and it naturally has implications beyond the ISS.  As we move further from Earth, we have to be prepared for many eventualities.  And a 3D printer allows for a wide range of possibilities.

Remember that in Apollo 13, they had to repurpose whatever things they could find on board to ensure that the astronauts could return home.  Imagine how that could have gone if they could have made literally anything out of an idea.

Another whitewashing of history?

This is an interesting long-form piece about how Harvard wanted to know about how the slave trade was handled at the university.  Its worth a read... 

...but for anyone who wants the cliffs notes version, essentially someone was hired to do the research and what he found was that there was a lot of overlooked elements of slavery that helped build the university, and even several prominent people involved with the founding were slave owners.  The researcher was asked to limit his findings because this was a source of shame.  And when he didn't, he was let go, and the university turned the research over to a company doing more genealogy and less shining a light on slavery.

Which is shameful in its own right.  The past happened.  Why can't we just own up to it and move on?

Relay 2 comes to life to emit a pulse of radio waves

In 1964, NASA launched Relay 2 as an early satellite.  The main objective was to determine the feasibility of launching a satellite that could remain in place and allow for data to be relayed from future manned missions (like the moon shots).  

Having fulfilled its purpose, the satellite was decommissioned in 1967, and just left to sit in a high orbit above the earth.  And then in mid-June of this year, it suddenly came to life and emitted a strong radio pulse - well beyond anything that could be easily explained.

Scientists are trying to understand what happened here, but its a really fun mystery for now.

Wireless power transmission

I've talked in the past about the possibilities for wireless power transmissions.  DARPA has achieved this - by sending 800 watts of power over a distance of 5 miles!

The pulse was transmitted with an approximate 20% efficiency, and some of the power it transmitted was used to make popcorn. The researchers have bigger ambitions for the system's use in the field, however, suggesting that it could be used to power unmanned aerial vehicles (UAVs).

Popcorn.  Seems so innocent, given that this is an advanced research branch of the army.

Removing microplastics from water

Researchers have found a plant-based substance that provides a way to to suck up microplastics.

... researchers found that extracts from okra and fenugreek can remove up to 90 percent of microplastics from ocean water, freshwater, and groundwater. These results were recently published in the journal ACS Omega.

 Its early, but the results are interesting!

AI and Disney's sacred IP

Disney is - and always has been - very territorial about their intellectual property.  I mean look at Mickey Mouse, and how the Disney company sought to maintain the copyright over his likeness for as long as they did, going so far as to lobby congress so that they could maintain that copyright for longer than originally intended.

And now along comes AI.  And several companies are using it to generate content that (seemingly obviously) infringe on those copyrights.  Only the courts have been kind of letting a lot of it slide as these new technologies are "training."

But Disney is not taking that lying down and is suing to protect their IP from this type of infringement.  Its worth watching to see how this plays out, and whether the other players with significant works being re-created ultimately join the effort to stop AI companies from using and monetizing on the works of Disney (and others).

Here's an article from June that lays it all out.  https://www.bloomberg.com/news/newsletters/2025-06-22/inside-disney-s-campaign-to-protect-darth-vader-from-ai 

Possible Disney World expansion?

Disney submitted their 20 year plan for land usage to the Central Florida Tourism Oversight District (the state-run board that replaced the Reedy Creek Improvement District).

Most of it is the pro forma land usage plans.  But there were a couple of interesting items within it.  First was that they set aside property for two "minor theme parks."  These would be things like water parks or amusement park-type areas.   

But, more interestingly is that they left space for a 5th theme park.  Speculation is running wild on the internet on what that means, and when it could happen. But the reality is that there is (to this point) no concrete plan in place.  This is speculative, and leaves room for future growth, should Disney decide to expand like that. 

Still its important to note that Disney is planning for more growth.
