🧊 New research shows ice is slippery because of electrical charges — not pressure and friction.
For almost 200 years, the prevailing explanation for ice’s slipperiness was that friction or pressure from a skate, boot, or tire melted a microscopic film of water on the surface, creating a lubricating layer. A new study from Saarland University has overturned that long-standing idea.
Instead, the true cause lies in the electric fields generated by molecular dipoles. When any object contacts ice, the partial charges in its own molecules interact with the highly ordered dipole arrangement of water molecules in the ice crystal. This electrostatic tug-of-war loosens the topmost layer of the ice lattice, transforming it into a thin, disordered, quasi-liquid film—without any need for heat or significant pressure.
Remarkably, this self-lubrication mechanism works even at temperatures approaching absolute zero, where thermal energy is virtually absent and conventional pressure-melting or frictional heating theories completely break down. In those extreme conditions, ice remains slippery simply because its surface molecules are electrically vulnerable.
The discovery fundamentally rewrites our understanding of one of nature’s most familiar phenomena. Beyond settling a centuries-old debate, it has immediate practical implications: from designing better winter tires and non-slip surfaces that actually work on ice, to engineering superior skis, ice skates, and even advanced nanomaterials that perform reliably in cryogenic environments.
By revealing the dominant role of intermolecular electric forces, the research opens entirely new avenues for controlling friction and adhesion at the molecular scale—potentially transforming fields from winter sports equipment to aerospace and nanotechnology.

Ukrainian forces have begun training and testing exoskeletons for battlefield use. Soldiers from the 147th Separate Artillery Brigade are using them in the Pokrovsk sector for both logistics and frontline operations. The goal is to reduce physical strain, especially when loading heavy artillery shells into howitzers without automatic loaders. Artillery crews can handle up to 1200 kg of ammunition per day, and early tests show that exoskeletons help them work faster and with less fatigue Above all, by improving the conditions for those soldiers on the front lines who handle such heavy loads, plus the stress of work. Seeking to reduce overall fatigue in the troops

🇺🇸 Blue Owl Capital just disclosed that investors tried to pull 40.7% of one fund and 21.9% of another in a single quarter, and both funds gave the same answer, you can only have 5% back, and everyone else waits in line.
This is a bank run, not a normal withdrawal.
Wall Street spent the last decade selling millions of investors on something called semi-liquid private credit, higher yields, steady income and the promise you could get your money back every quarter if you needed it. What they buried in the fine print was what happens when too many people try to leave at the same time.
Analysts who have covered private credit for decades say nothing on this scale has ever been reported before at any major private credit manager.
These funds do not hold stocks you can sell on a Tuesday afternoon, they hold private loans to mid sized companies that cannot be liquidated quickly without destroying the price for every investor still trapped inside.

🇺🇸 President Trump wants to switch to war economy in 2027 with massive increase in military spending and massive cuts to healthcare and other domestic agencies
Once a deficit hawk — he said in 2016 that he thought he could balance the budget in five years — Trump ended his first term with $7.8 trillion in added debt. His 2027 proposal is expected to give an update on 10-year deficit projections currently estimated at around $16 trillion.
The GOP's message for the Midterms will be focused on the "need" for a massive defense build up while the Democrats' message will be focused on affordability.
The fiscal 2027 budget will be the first time Trump puts his second-term governing agenda into one comprehensive document — with the numbers to back it up. The budget he released last year lacked detailed line-by-line spending targets and the economic assumptions necessary to project the long-term cost of his proposals.
Investors in US Treasuries will be looking to see if the debt and ...
