New researsh 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.

Doing this makes games infinitely more fun

I was looking forward to seeing this today. Geoff, my disappointment is immeasurable, and my day is ruined. Biggest GOTY snub ever!

@jowig21 @comunidademc basicamente é o mesmo mod no começo tinha o TMI (Too Many Items) que era puramente pra cheat, o NEI (Not Enough Items) foi criado pra mostrar receita mas o desenvolvedor abandonou no minecraft 1.8, então criaram o JEI (Just Enough Items) que atualizam a literalmente uma década

@comunidademc nunca entendi se tinha diferença do JEI pro NEI, mas qnd era criança eu só usava o NEI

🚨 JEI é o PRIMEIRO mod da história a atingir 500 milhões de downloads.

no one talks about the horrific event of meeting someone who is exactly your type

@luttien_ tá certo, só não acho q tem muita distinção pq nenhum deles vem do vazio em si, só foram corrompidos tem alguns meio ambíguos também como lissandra, gwen e shaco mas não acho que faz diferença, pra mim tá certo assim

@BSmuca concordo, a questão de usuário de artefatos mágicos merece uma nova categoria VoidBorn Human é uma subcategoria pra "humano modificado"

new gta confirmed half life 3 confirmed close enough welcome back 2013

I don't think enough people realize that Valve literally just took the most common Steam Hardware survey results and made a console out of it. That's literally all the Steam Machine is

emilia perez was so funny. we made a movie about a mexican trans woman. is it good? no. do trans people like it? also no. do mexicans? even less. well at least it’s platforming a trans actress. oops she’s hitler.

🚨ACABOU O MISTÉRIO! O tema da redação do ENEM 2025 foi: "Impactos da cantora virtual Hatsune Miku na sociedade brasileira."

minha opinião mais unwoke é q eu gosto da flanderização do Brasil fodaseeee vamos conquistar o mundo igual o Japão. olha a capivara, olha o guaraná, olha o bronzeado. (só acho q existem limites, principal e qnd se refere á sexualização e turismo sexual

Fallen e Faker ganhando um título Mundial no mesmo dia, no mesmo país e na mesma cidade (e quase na mesma hora). Bizarro o quanto eles provam todos os dias que a idade é somente um número nos esportes eletrônicos. Vida longa aos Reis!
