They’ve been talking about how spider web is stronger than steel since I was a kid. By now I was expecting to see bridges and tall buildings made using spider web.

I wouldn't mind if these videos were longer and contained more detailed information.

I've always had a fascination with spiders and their webs! Some people go around killing every spider they see and it winds me up. I knew a guy called Lesley who use to stamp on every spider, I used to have a got at him every time! Spiders are cleaners and crafts men, their silk also has antiseptic and electric properties and can stretch up to 30% of it's length!

Does the silk strand vary in shape for each spider and is there a spider silk that has the highest tensile strength compared to others?

Future arachnologist/entomologist here. Nice to see that brown recluses are getting more interest from the scientific field apart from their venom. They're pretty cool spiders, even if they are the only species I actively dislike. Surprised me in my bed far too many times to count in my childhood...little ninjas in disguise, I tell you.

Spider silks protein structure on an atomic level is like interlocked spirals of protein, that lock together. Their silk is estimated to be the strongest natural fibre know to man!

This headline, "Spider silk is five times stronger than steel—and now scientists know why, " may very well be true, but it has nothing to do with this video.

This video contains the following information: spiders' "silk" is strong. Spiders' "silk" is made up of "nanofibers, " and its shape is flat. There are also interesting graphics. There is nothing here about how any scientists know what.

The editor should be given retraining, possibly in coffee stirring, and reassigned to something more suited to her abilities.

That moment when you're interested as hell in this news but you have arachnophobia and the video consists of zoom ins on spiders.

Suffer through it...do it for the science...

Science is knowledge
Knowledge is power
That power gives my life reason

why did they choose to collect silk from one of the most venomous spiders? Why not use the good ole daddy long leg?

So would you build your home from steel or spider web?

Please stop these misleading/ fake science article, 500% Elongation cannot do anything good of structural steel.. the allowable steel wire elongation is only 0.5 to 1.0%, means the steel wire is 5 times more Rigidity than your (raw) Silk. As same catagory as Kevlar fibre, your silk can ONLY be good as impact-absorber, just like other resins. But not for Structure/fixed cables.. (the raw/untreated Silk has expired life under 2weeks at most, before rotten/ degraded away.!! Please stop creating pseudoscience here & there.

We Muslims knows about this 1400 years ago, Spider web properties was written in Quran since then, Alhamdolellah for Islam .
