A sting from a bee or wasp can be painful, and cause further problems for those with allergies. Yet pain may not be the insect’s intention – at least not at first. Here, a scanning electron microscope zooms in on a stinger from a Vespula vulgaris wasp – its serrated ‘lancet’ ready to poke out and pierce flesh. Computer analysis shows that the stinger has a flexible tip adapted, potentially, to reduce initial pain and shock – giving the insect more time to release its venom for maximum impact. These macabre mechanical insights are guiding the design of new painless ‘microneedles’, flexible at the tip to reduce pain and copying the exact angles of entry used by wasps and bees to deliver chemicals efficiently. Scientists believe different insects, including mosquitos, have other mechanical secrets. Perhaps these will inspire biomimetic devices to treat the exact conditions that bites and stings help to spread.

My mum @sprinkleofamy__ has made a few changes to my account but for now I have a funny story to tell well it wasn’t funny at the time... A few weeks ago I was playing in the garden with my uncle Charlie and I decided I would eat a wasp 🐝 I obviously got stung and my mummy and daddy had to rush me to the vets to have a steroid injection but I was a brave boy. This was me afterwards I hope it makes you giggle 🐶 #cockerspaniel#cockerspanielpuppy#waspsting#vets
Plantain to the rescue! We are cleaning out an old storage building. The weather is turning colder, so wasps are congregating inside in hopes of wintering over safely. Even though they're sluggish due to the cold, they can still sting. .
One somehow got under my pants leg and into my sock. Ouch!! Immediately, I ran into the yard in search of wild-growing plantain. I stuffed a couple of leaves into my mouth, gave them a quick chew, and put the gross, green glob on the sting. Almost instantly, the pain stopped.🙌
Plantain is almost miraculous for stings, and both long-leaf and broad-leaf versions grow plentifully in most untreated yards. (Our "grass," in fact, is green more from the many weeds--including medicinal plantain--than from actual grass!😂)
P.S. Did you know you can also eat plantain?! Try adding some in the blender when you make a smoothie. 😋
My poor thumb, I walloped it with the hammer because I was having difficulty holding work due to the wasp sting on my middle finger. This sting is 3 days old now & my finger is like a sausage & is very sore. So I’ve given in, downed tools & left the workshop. Sometimes you have to ☹️#waspsting#sore thumb #lifeintheworkshop
All time worsted creepy crawly wake me up moment by a wasp crawling on my shoulder following by a sting. Glad I am a get up and go kind of person anyway otherwise that could have been and interesting view #waspsting#whilstsleeping#oniononsting#getupandgo
They got me!! Check out my fat left hand 😆
Something calming about being around animals eh’??! Did I say that earlier on today 🐝🐝
The sting is on my middle finger, but my whole hand is swollen....3-4 days it’ll be back to normal.
Wasps are still out apparently 😟 I was at Giant Tiger , felt the stinging and got my kids to check. They saw the wasp and ran as far away from me as they could! 😫 I had to go up to the til and get them to get it out. I’m sure it was quite the sight. 😭 #motherfucker#waspsting
I’m terrified of wasps...I scream, run and occasionally jump out of moving vehicles in the fall when I see one!! They get nasty this time of year. Today I got stung in a parking lot trying to swat a wasp away from my face. A nice old lady asked me if I was ok and in my calmest voice with a fake smile I looked her dead in the eye and said “HOLY FUCKING SHIT THAT LIL FUCKER FUCKING GOT ME!” Lol my daughter was in the car I didn’t want her to see how much that sting hurt! It still hurts! #sorrylady#waspsting#stings#ouch#dontfreakout#kidswatching#smile#calm#swearsweetly#singlemom#family#daughter#familyof2
I thought it would have been a good idea to play with a wasp whilst mom & dad was at work. Turns out, it wasn't the best of ideas. Dad had to take me to the vets for an emergency appointment because my paw has really swollen up! I'm all cuddled up to mom now so I'm ok. Watch out for those wasps fur friends. 🐱❤❤❤
Prepare for days the 16th and 17th of #inktober !! I've been playing a bunch of Pokemon Go, I don't know if you've picked up on that, and I managed to catch a Porygon the other day so of course I was gonna draw one for #Angular . Then for #Swollen I drew this poor guy. He just stepped outside, into the sunshine, looking for a good time and boom - bad guy wasp comes along, pops him full of venom and before you know it... BALLOON. Sucks to be him, hope he has some allergy tablets...
I took a day off from Inktober yesterday. I could kinda feel myself getting a little burned out by putting myself under the pressure of having to get something drawn every day - even though I AM having a load of fun doing this. I knew I had today off so I'd have more than enough time to get caught up.
So yesterday I nearly got hit by a car. And today I got stung by a #wasp and mum got stung at the vet! My back leg is as big as a ham. If anyone tells you dogs are less hassle than kids they’re lying. #myitchydog#waspsting#vetvisit
