| Scientists discover secret about a honey bee's stinger
Scientists from Macquarie University in Australia have made an exciting discovery about honey bees. The scientists found out why a bee's stinger keeps putting venom into a person's skin after it leaves the bee's body. The scientists used high-speed cameras to film the tiny stinger, which is only two millimetres long. The video showed that the stinger works like a pump. It has two small parts that move backwards and forwards. These parts push the stinger deeper into a person's skin to help keep the venom flowing. The lead researcher said the design of the pump was "unique". She hopes her discovery will help companies make tiny pumps that could give medicine to people. |
