Scientists in Australia have made an exciting discovery about honey bees. The scientists found out why a bee's stinger puts venom into a person's skin after it comes off the bee's body. The scientists used high-speed cameras to film the stinger. The video showed that the stinger works like a pump. It has two small parts that move backwards and forwards. These parts help keep the venom flowing into the skin. A researcher said the pump's design was "unique". She hopes her discovery will be useful. Companies might make pumps that could give medicine to people.

A bee sting can be very painful. Most people have swelling after a sting. It can be dangerous for people who have allergies. Some people have a serious reaction. Their face or throat may swell up, or they may have trouble breathing. If someone is stung, they should remove the stinger quickly. This will stop more venom going into the body. The person should also wash the area with soap and water. In addition, it is a good idea to put an ice pack over the sting. If the person feels unwell, someone should call emergency services.
