The team then used a neat trick to introduce carbon nanotubes and graphene flakes into the spider silk. They simply sprayed the spiders with water containing the nanotubes or flakes and then measured the mechanical properties of the silk that the spiders produced.
"We measure a fracture strength up to 5.4 GPa, a Young's modulus up to 47.8 GPa and a toughness modulus up to 2.1 GPa," say Lepore and co. "This is the highest toughness modulus for a fibre, surpassing synthetic polymeric high performance fibres (e.g. Kelvar49) and even the current toughest knotted fibers," they say.
In other words, giving spiders water that is infused with carbon nanotubes makes them weave silk stronger than any known fiber.
Me: "That's called a Butter Diet."
They were voracious predators, gobbling up anything that crossed their path, including worms, shrimp and other marine creatures. The phallic-shaped animals, officially known as priapulids, emerged during the 'Cambrian explosion', a period of rapid evolutionary development about half a billion years ago, when most major animal groups first appear in the fossil record.
"Modern penis worms have been pushed to the margins of life, generally living in extreme underwater environments," added Dr Smith. "But during the Cambrian, they were fearsome beasts, and extremely successful ones at that."
This crazy, hairpiece-looking clump of yellow fluff is actually a rare caterpillar that only looks like Donald Trump's hair.
Interestingly, and coincidentally, approaching the Donald Trump Caterpillar (scientific name: Megalopyge opercularis) can be very dangerous, particularly if you come in contact with the business end of its yellow mane.
"If you touch that thing, it would seriously hurt," Torres, a field biologist, told the UK Daily Mail. "It has these little hairs that can poke into your skin and release a venom."
Just like the real Donald Trump. How uncanny!
