Submission + - New spinning drone hides in plain sight (northwestern.edu)

fahrbot-bot writes: For years, researchers have tried to design invisible drones and robots using camouflage, transparent materials or light-bending optical systems. But the Northwestern team instead used a concept called “motion blur” — the same effect that makes fast-spinning fans and propellers seem to disappear.

Called the “Phantom Twist,” the drone spins up to 25 times per second, which is too fast for the human eye to see clearly. While it isn’t completely invisible, it morphs into a ghostly smudge that seamlessly blends into the background. The work eventually could lead to drones that monitor wildlife, survey the environment and inspect infrastructure with less visual disruption.

The Northwestern team presented the work on July 16 at Robotics: Science and Systems 2026 in Sydney, Australia. The talk, “Computational Design of a Low-Visibility UAV Using Human-Aligned Perceptual Metric,” is part of the session “Robot & Sensor Design.”

A tariff would help, I mean, Trump suggested it would work against the Canadian wild fires.

Maybe some corporal punishment on the wild fires, like When Persian King Xerxes Ordered His Soldiers to Punish the Sea by Lashing It

Determined to finish the Greeks once and for all, Xerxes amassed a massive army. He planned to cross the Hellespont using a bridge he had constructed. When his forces reached Sardis, however, a violent storm destroyed the bridge.

When his men reported the disaster, Xerxes was furious. He was enraged both at the sea for demolishing the structure and at the architects for failing to make it strong enough to withstand the storm. Resolute, he determined to punish both the waves and the workmen.

According to Herodotus, Xerxes commanded his men to scourge the sea with a monstrous whip and to cast heavy chains into it, symbolizing both his defiance of its power and his determination to assert control over it.

As for the men who had constructed the bridge, which had proved incapable of withstanding the force of a winter storm, Xerxes ordered that every one of them be beheaded.

The story of Xerxes and his extraordinary decision to order his soldiers to punish the sea by whipping it was viewed by Greek historians and later thinkers as a symbol of imperial arrogance and the illusion of absolute power, portraying the king as a god.

Honestly, I wouldn't put it past him - on the other hand, this kind of thing isn't working for him with Iran ...

Cape Coral!
This is a city smart enough to water their street medians on a hot, summer day.
This is a city where you could literally die in your sleep as your house falls into a sinkhole.
This city (Lee County) and Las Vegas were grounds zero for the 2008 financial crisis.
This is the state where healthy young people subsidized the legalized opiod crisis.

In 2007 you could just walk up to a newly built home, kick in the door, and take the appliances because no one was there to stop you or live in that house. There are still entire blocks with only a few new houses on them.

It's *barely* above sea level today, and I'll be surprised if you can walk on it 20 years from now.

Also Arctic Sinkholes (NOVA: S49E01, 53m) releasing massive amounts of methane as frozen permafrost melts.

Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive craters. In Alaska, a huge lake erupts with bubbles of inflammable gas. Scientists are discovering that these mystifying phenomena add up to a ticking time bomb, as long-frozen permafrost melts and releases vast amounts of methane, a potent greenhouse gas.

Tariffs are the largest transfer of wealth in US history. You pay them, then the courts strike them down, and companies collect the refunds. Oh, and the prices aren't going back down to pre-tariff levels either.

Even if/when tariffs are legally and properly implemented/applied, consumers are (almost always) ultimately paying them, not the foreign companies/governments - and it boggles the mind how certain segments of the population don't get this last bit, just google "tariff" to see how an import tax works.

I mostly do heavy multi-disciplinary engineering problems (these I also use for checking an AI, as they're typically not good at these sorts of problems), complex coding, OS analysis, stuff like that. However, sometimes I do throw the occasional odd-ball - I've used ChatGPT to propose a workable quantum mechanics that will cope with Doctor Who canon, for example, and to produce an outline for a story in which symphonic metal appears in 1964 that is compliant with current sociological and psychological models of behaviour.

Claude Opus 4.6 was coping surprisingly well with just about everything I threw at it (but ran out of credits fast), but Opus 5 is churning out incoherent babblings to the point I'm worried I may have accidentally summoned Cthulhu.

But Gemini, Grok, and DeepSeek got hopelessly confused on just about everything past a very low level of complexity. They can handle large problems, yes - Gemini has a huge context window - but complex interactions baffle them.

ChatGPT is able to identify issues correctly, but can only outline solutions, it's just not good at depth. 5.6 is a lot better, but still not good at deep answers. ChatGPT is also prone to agreeing for the sake of it, which makes me nervous about trustworthiness.

That is fair enough. I've been trying out Kimi on the free model, and have subscriptions to Claude and ChatGPT. If Kimi is actually as good or better than ChatGPT, at the pro level, then it might be worth my while moving over as ChatGPT has become very disk-hungry of late and I'm pushing right to the very limits on what it can reliably process.

Submission + - Trump Administration Admits Canceling Grants to States That Did Not Vote for Him (nytimes.com)

fahrbot-bot writes: The New York Times is reporting that Federal officials said in court documents that they halted billions of dollars in funding for energy projects to states “based solely” on whether they backed President Trump in the 2024 election.

In little-noticed court documents, federal officials acknowledged this month that they had terminated the funding “based solely” on political criteria, targeting projects in states that were represented by Democrats and had voted for Kamala Harris, the party’s presidential nominee, in the 2024 election.

After reviewing its spending, the Energy Department last fall created a list that recommended canceling more than 600 grants awarded by the Biden administration for a wide range of novel energy projects. That list included funding for projects in states represented by both Republicans and Democrats.

“With one exception,” a lawyer for the Energy Department conceded in a court filing this month, “the 284 terminated grants had a recipient location and/or at least one place of performance in a state that awarded its electoral votes to Kamala Harris in the 2024 election and has two Democratic-caucusing senators.”

The lawyer acknowledged that none of the grants were included in the October terminations “based on any programmatic, statutory, cost-reduction or performance-based factor.”

In contrast, the administration left untouched hundreds of additional energy grants in states that were represented by Republicans and had backed Mr. Trump in the last election, even though the Energy Department had recommended canceling them, the government confirmed in the July court filing.

The filings also appeared to undermine the congressional testimony of Energy Secretary Chris Wright, who spoke about the cancellations in a June House hearing: “No decisions were made on politics.”

That humans have sufficiently directional hearing is perhaps the most impressive part. Once you have that, then the rest really just follows,

However, this continues the unexpected senses in humans, one of the first discovered was that humans have a weak magnetic sense.

The potential, both in fact (if you can "see" walls and gaps by clicking then you can presumably navigate a cave even if your light source goes out) and in fiction (this one should really be obvious), is considerable.
