Science commentator Laurie Winkless joins Kathryn to talk about new research that's used tree rings to confirm last year's northern hemisphere summer was the hottest in 2000 years.
Researchers at MIT have found a way to eliminate fibrosis or scarring that can happen around medical implants by using a hydrogel adhesive.
And we've known since the early 90s that the surface of Venus was scattered with volcanoes - now new imaging technology and computer simulations has concluded they may still be erupting.
