Salty Swirls

Flamingos soar over swirls of salt and algae in a lake in Kenya’s Rift Valley. Shaped by winds, currents, physics, and chemistry these eddies reflect the motion of the water, evaporation patterns, and more. Without more information, it’s hard to say exactly what shapes the pattern, but it does appear reminiscent of a Kelvin-Helmholtz instability in places. (Image credit: B. Hayden/IAPOTY; via Colossal)

But as of now, this is not the boom #Trump promised, & his ability to blame his Democratic predecessor, Joe #Biden, for any economic challenges has faded as the world #economy hangs on his every [erratic] word & social media post [rant].

When Friday’s #jobs report turned out to be decidedly bleak, Trump ignored the warnings in the data & fired the head of the agency that produces the monthly jobs figures.

It's #Trump's #economy now. The latest #financial numbers offer some warning signs

For all of Trump’s promises of an economic “golden age,” a spate of weak indicators this week told a potentially worrisome story as the impacts of his policies are coming into focus.

#Jobs are dwindling. #Inflation is ticking upward. #Growth has slowed compared with last year.

It was a stunning about-face by the same lawmakers who just last week had supported the previous #law undermining the agencies, which drew public fury.

Demonstrators outside parliament cheered the result when it was announced. President Volodymyr #Zelensky …signed the law less than 2 hours after it was passed….

Inaction by parliament would have prolonged the political #instability in a country besieged by #Russia’s continuing war.

See the Solar Wind

After a solar prominence erupts, strong solar winds flow outward from the sun, carrying energetic particles that can disrupt satellites and trigger auroras if they make their way toward us. In this video, an instrument onboard the ESA/NASA’s Solar Orbiter captures the solar wind in the aftermath of such an eruption. The features seen here extended 3 solar radii and lasted for hours. The measurements give astrophysicists their best view yet of this post-eruption relaxation period, and the authors report that their measurements are remarkably similar to results of recent magnetohydrodynamics simulations, suggesting that those simulations are accurately capturing solar physics.

Bow Shock Instability

There are few flows more violent than planetary re-entry. Crossing a shock wave is always violent; it forces a sudden jump in density, temperature, and pressure. But at re-entry speeds this shock wave is so strong the density can jump by a factor of 13 or more, and the temperature increase is high enough that it literally rips air molecules apart into plasma.

Here, researchers show a numerical simulation of flow around a space capsule moving at Mach 28. The transition through the capsule’s bow shock is so violent that within a few milliseconds, all of the flow behind the shock wave is turbulent. Because turbulence is so good at mixing, this carries hot plasma closer to the capsule’s surface, causing the high temperatures visible in reds and yellows in the image. Also shown — in shades of gray — is the vorticity magnitude of flow around the capsule. (Image credit: A. Álvarez and A. Lozano-Duran)

Cap (pileus) clouds over the cumulus in the mountains of southern New Mexico.

en.wikipedia.org/wiki/Pileus_(

Note the Skew-T trace for this location. Winds are fairly light in the convective zone, but above that the winds increase. (But wind direction does not change.)

Humidity hits a maximum just above the convective layer, which is where the cap clouds form.

#WarrenBuffett warned Saturday of the dire consequences of #Trump’s #tariffs while telling the thousands of #investors gathered at his annual meeting that “#trade should not be a #weapon” but “there’s no question that trade can be an act of #war.”

Buffett said Trump’s trade policies have raised the risk of #global #instability by angering the rest of the #world.
“It’s a big mistake…when you have 7.5B people who don’t like you…, & you have 300M who are crowing about how they have done,” he said.

If you want a great documentary on the effect of tariffs with actual business holders in the computing / electronics space.
See how things are going and you as a consumer will be affected.

I highly recommend you boost / share, GN did a great job. Meet company founders, ceo's of small and big companies. Understand how they are dealing, with the current economy we are in, etc.

3 hours documentary.

#Arctic #warming could pose a threat to America’s #security too: #Alaska may have new vulnerabilities to both #China & #Russia; changes in #ocean salinity & temp might interfere w/ #submarine detection systems; extremes of climate change, including #permafrost thaw in Russia, may drive #economic #instability, social #unrest, & territorial claims.

A Stellar Look at NGC 602

The young star cluster NGC 602 sits some 200,000 light years away in the Small Magellanic Cloud. Seen here in near- and mid-infrared, the cluster is a glowing cradle of star forming conditions similar to the early universe. A large nebula, made up of multicolored dust and gas, surrounds the star cluster. Its dusty finger-like pillars could be an example of Rayleigh-Taylor instabilities or plumes shaped by energetic stellar jets. (Image credit: NASA/ESA/CSA/JWST; via Colossal)

Ultra-Soft Solids Flow By Turning Inside Out

Can a solid flow? What would that even look like? Researchers explored these questions with an ultra-soft gel (think 100,000 times softer than a gummy bear) pumped through a ring-shaped annular pipe. Despite its elasticity — that tendency to return to an original shape that distinguishes solids from fluids — the gel does flow. But after a short distance, furrows form and grow along the gel’s leading edge.

Front view of an ultra-soft solid flowing through an annular pipe. The furrows forming along the face of the gel are places where the gel is essentially turning itself inside out.

Since the gel alongside the pipe’s walls can’t slide due to friction, the gel flows by essentially turning itself inside out. Inner portions of the gel flow forward and then split off toward one of the walls as they reach the leading edge. This eversion builds up lots of internal stress in the gel, and furrowing — much like crumpling a sheet of paper — relieves that stress. (Image and research credit: J. Hwang et al.; via APS News)

Continued thread

The growing conviction that #Trump will stick by massive new #tariffs regardless of the economic fallout — amplified by Trump’s refusal to rule out a #recession on Sunday — fueled the drop across equity markets. The Dow Jones Industrial Average closed down 890 points, 2%, while the S&P 500 fell 2.7% & the Nasdaq Composite plummeted 4%.

#Trump’s senior advisers downplayed fresh economic turbulence Monday as the admin’s escalating #TradeWar deepened a sell-off on #WallStreet & renewed fears about the stability of the US #economy.

As all 3 major US #stock indexes slumped, Trump’s team projected confidence that the volatility would prove temporary & that an economic boom set off by tax cuts [for #corporations & the #wealthy] would follow later this year.
