El Reg reports:

Limpets – a type of aquatic snail – [...]need high strength teeth to scrape algae off rocks. [...] Scientists used atomic force microscopy to pull the teeth apart at the atom level. They found the teeth contain a hard mineral known as goethite, which forms in the limpet as it grows.

[...]Professor Asa Barber from [Portsmouth] University's School of Engineering said: "Until now we thought that spider silk was the strongest biological material because of its super-strength and potential applications in everything from bullet-proof vests to computer electronics but now we have discovered that limpet teeth exhibit a strength that is potentially higher."

The research also discovered that limpet teeth are the same strength no matter what the size. Usually, the bigger a structure, the more prone it is to flaws. Limpet teeth break this rule, as their strength is the same no matter what the size.

These structures could be mimicked and used in high-performance engineering applications such as Formula 1 racing cars, the hulls of boats, and aircraft structures.

[...]The research was published [February 18] in the Royal Society Journal Interface.[1]

    Formula 1 cars.

    Formula 1 cars I could care less about, but using the material, which they said would be cheap, in components in EVs would be welcome if it meant lighter cars with longer range.
