      Great question.

      Breakthroughs in science are actually quite rare. Many of them have already been made by hard working and dedicated scientists. A lot of what scientists do now is try to make the breakthroughs we know about even better.

      However, I have done some research were I have created a new tool to help doctors and patients understand scientific evidence about different treatments they may be talking about for their health.

      I tried to make the tool really easy for people to know if a treatment is going to work and whether there will be any side effects. I am now going to try it out on patients and doctors to see what they think of it. Hopefully they will find it useful and help them when they have to make decisions about treatments for their health conditions.

      If you want you can see the tool for yourself here (page 39 and 40 of the document): https://www.researchgate.net/publication/267076443_Presenting_Evidence_of_Effectiveness_of_Interventions_and_More_-_The_Evidence_of_Effects_Page

      I’d welcome your comments on it too (you can post them on the website)!

      I discovered that if you swap out a few oxygen atoms for some sulfur atoms in a certain type of molecule, it will affect its properties, making it more colourful and making it much easier to give electrons to the molecule.
      This makes it a lot more useful for things such as solar cells.
