Silk spun by graphene-fed spiders is one of the strongest materials on Earth

Scientists have found a way to increase the overall strength and durability of spider silk. After feeding a spider a small amount of graphene and carbon nanotubes, the creature produced webs that were five times stronger than normal.

Spider webs are already strong enough to restrain small insects unlucky enough to fly into them, and soon, they may be capable of carrying the weight of a person.

In a new study published in 2D Materials, Nicola Pugno at the University of Trento in Italy and his team detail how they cranked arachnids’ already impressive metabolic process up to 11 by adding graphene and carbon nanotubes to a spider’s drinking water.

Afterward, the spider produced silk as it normally would, but the silk was five times stronger, putting it on par with the likes of pure carbon fibers and Kevlar — the strongest materials on Earth.

hey reblog this if you think girls can study and excel in computer science

im scared that tomorrow imma fuck around and look at the sun on accident

ok kids repeat after me

vinegar and bleach makes chlorine gas, which is highly toxic

ammonia and bleach makes chloramine, which is highly toxic

rubbing alcohol and bleach makes chloroform, which is highly toxic

hydrogen peroxide and vinegar makes peracetic/peroxyacetic acid, which can be highly corrosive

be careful about your cleaning products and dont get yourself injured or potentially killed ok

5 things you didn’t know about...bone-healing nanofibres

Credit: Riitta-Leena Inki

1. They are thin-film and fibrous biomaterials with similar structures and regeneration rates to that of bone.  

2. They were developed by Jani Holopainen, a doctoral researcher in the Department of Chemistry at the University of Helsinki, Finland.

3. The hydroxyapatite fibres are produced on a needleless, twisted wire electrospinning apparatus.

4. They could be used in bone implants and as scaffolding for bone regeneration. Cellular tests have been made already, but medical application is a way off.

5. The nanofibres would be used as a scaffold on the bone fracture or fault, activating the bone cells to reproduce. As the new cells are generated the nanofibres disintegrate, meaning there would be no need for further surgery to remove the nanofibre scaffold.

kinda cool to think how someone somewhere is having the best day of their life today. someone’s hearing “i love you” for the first time today. someone’s gonna meet the love of their life today. someone’s gonna get the job of their dreams today. it’s someone’s best day today. and guess what binch? tomorrow it could be ur best day so keep going

It’s kind of fucked up when you realize the image of the quaint 1950s leave it to beaver family with the housewife and hard working husband is a propaganda model that had to be adopted to justify stripping women of their jobs they were able to get during WWII. Like women literally proved they could keep an industria wartime economy afloat without men and society had to craft some serious insidious shit to get them back into the home.

me as a child: labs are spotless and big and scary…………everything is high tech and everyone is super smart and knows everything…….

all actual labs ever:

sure he’s well versed in leftist theory but does he do the dishes
