This week on Dear Science Milly and Beth are joined by Joel Rindelaub the day after his birthday to talk all things science! Sleep masks are proven to work in a study exploring human sensitivity to light, then it's out to space where the James Webb telescope has made some more puzzling discoveries: this time it's galaxies that are far bigger than we thought they would be, and finally finishing off with the fact than anyone can be good at maths, we just need good teachers + tutors + working hard.
