About 300 scientists work at the Natural History Museum, uncovering science every day. From human origins, forensic investigations and discovering new species, to better ways to conserve biodiversity and control disease and much much more.
It's not a secret, it's just that they work quietly behind the scenes. But how many of the Museum visitors know about this? Hopefully, some of the 4.7 million visitors in the last year do (there's been nearly a million more visitors than the previous year).
And visitors to the landmark Darwin Centre, which has been open 1 year today, would have seen some of what the scientists do, day to day in their jobs.
Relax and have a drink at one of the 5 bars at the 2010 event.
If you want to find out more about the work that goes on or science in general, then 50 Museum scientists will be at the Museum's biggest ever Science Uncovered After Hours event next Friday.
This exciting one-off evening event will be a festival of science, with drinks and nibbles, tours, talks and more.
There is even a free gin and tonic for visitors who bring along their most interesting specimen or story to the Hendrick's Bar of Curious Concoctions in the Darwin Centre!
Set mostly in the iconic Central Hall, there will be experts to tell you about some of the most unusual Museum specimens in the Face to Face science stations.
Behind-the-scenes specimens, like this Tower of London lion skull, on display for the Science uncovered event in September 2010.
You can enjoy a drink and a chat with scientists at The Science Bar or go on one of many Museum tours.
There's also Nature Live talks on topics from stegosaurs, and forensics to the amazing Archie, the giant squid.
And bring along your unidentified specimens or photos as the Natural History Roadshow has experts to help identify them for you.
Science Uncovered After Hours event is on Friday 24 September from 4pm to 10pm. It is part of the European Researchers' Night with events taking place in 200 cities.
