Bioenergy with carbon capture and storage (BECCS) can reverse the global warming trend and push temperatures back below the global target of 2°C above pre-industrial levels, even if current policies fail and we initially overshoot this target.
Li-fi or light fidelity is a wireless technology which was discovered by physicist and professor Herald Haas. It uses visible light instead of radio waves to transmit date rate at speed of Tb (Tera bytes). It is a green technology and has a future access scope.
This very simple toy uses a magnetic chain reaction to launch a steel marble at a target at high speed. The toy is very simple to build, going together in minutes, and is very simple to understand and explain, and yet fascinating to watch and to use.
A mathematics student based at University College London (UCL) has worked out the secrets of how chocolate behaves in a chocolate fountain, answering the question of why the falling ‘curtain’ of chocolate surprisingly pulls inwards rather than going straight downwards.
