A new study shows that some spiders have turned their webs into poisonous webs.
Spider web is a tough natural material, light weight, high strength, corrosion resistance, and surprisingly sticky and elastic.
A 2011 study found that spiders use a chemical insect repellent to “arm” their webs to prevent other reptiles from approaching their prey or to prevent themselves from becoming prey by other predators.
Recently, some scientists have analyzed the molecules exuded from the silk-producing glands of the golden silk spiders and found that there are as many as 7 types of silk-producing glands in the golden silk spiders. The silk threads they secrete have different uses, including for Protect eggs, erect nets, and sticky catching silk for hunting. Scientists analyzed these 7 types of glands and discovered a series of neurotoxins. Once these toxin proteins ooze out of the spider’s glands, they will be suspended on the spider web’s catching silk in the form of sticky oil droplets.
Scientists extracted toxins from silk webs and tested them on bumblebees (natural enemies of golden silk spiders). The results showed that spider web toxins can break down the waxy protective layer of the horny layer of the hornet, and can anesthetize or even poison the hornet.
By spreading rock dust to farmland on the earth, it can help humans increase one-tenth of the global “carbon budget” (referring to the amount of carbon dioxide that humans can emit without causing catastrophic climate change). Rock naturally has the ability to absorb carbon dioxide. Grinding the rock into powder can increase the adsorption area and make it more capable of absorbing carbon dioxide. Human use of chemical fuels emits about 3.5 billion tons of carbon dioxide each year. Scientists have assessed the potential of rock powder to absorb carbon dioxide and are expected to eliminate 500 to 2 billion tons of carbon dioxide each year by 2050. If it can reach 2 billion tons per year, it is equivalent to raising the global carbon budget by 12%.
