š§ New research shows ice is slippery because of electrical charges ā not pressure and friction.
For almost 200 years, the prevailing explanation for iceās 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 filmāwithout 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 natureās 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 scaleāpotentially transforming fields from winter sports equipment to aerospace and nanotechnology.

Speaking at the WEF, Savor CEO Kathleen Alexander boasts about how her company is "saving the planet" from the evils of agriculture by replacing real butters and oils with synthetic versions made from carbon dioxide and methane. š³
"Savor is part of bringing transformation to the food system by re-imagining how we make an entire macronutrientāfats and oils."
"The result is that we can dramatically lower the planetary footprint of our food system."
"Our food system today uses about 50% of the habitable land on the planet. It's 20-30% of our greenhouse gas emissions."
"And we can reduce all of those by 50-100%."

š®š·ššŗšø Iran Is a Bigger Defeat Than Vietnam | Foreign Policy
At his second inaugural, U.S. President Donald Trump pronounced his hope āthat our recent presidential election will be remembered as the greatest and most consequential election in the history of our country.ā By losing his Gulf war, Trump has achieved that goal. His choice to launch a campaign against Iran was encouraged by others, but fully his own. It has led to a reversal that marks a strategic calamity far greater than the U.S. defeat in the Vietnam War.
Defeat in the Iranian war looks, on the surface, nothing like other U.S. military defeats. The speed of the war and its remoteness have lent an air of unreality to the whole endeavor. The White House has not been burned, as it was in 1814; there have not been protests against a nonexistent draft. The absence of substantial U.S. casualties in this conflict also masks the scale of the U.S. defeat. To be sure, the war has been deadly: Thousands of Iranians, ...
According to The Wall Street Journal, Donald Trump reviewed military options for a full-scale war against Iran to āfinish the job,ā but has decided, for now, not to move forward.
The report says Trump is concerned that renewed military conflict could hurt the chances of a diplomatic resolution and of dismantling Iranās nuclear program, and that heās shown willingness to let indirect talks in Qatar run past the August 18 deadline. He is said to be fine with continuing limited strikes on Iranian targets if Tehran violates the current temporary deal - as it already has, repeatedly.
How are those negotiations going?
Not well. It seems JD Vanceās āhistoricā face-to-face achievement was a one-off. Washington has been quietly downgraded from talking to the Great Satan to negotiating with the Little Satan instead - a senior Qatari official confirmed that U.S. envoys Steve Witkoff and Jared Kushner met Qatari officials in Doha, but there are currently no high-level U.S.-Iran meetings ...
