Today, a team of physicists announced they have created the world’s smallest doughnut. This incredible feat of engineering was achieved by using a process called “nanoprinting”. The doughnut, which is only a few hundred nanometers in diameter, is made of a special material called graphene. This material is incredibly strong and has a wide range of uses, from electronics to medicine. The doughnut is also incredibly resilient, able to withstand high temperatures and pressures without losing its shape. The breakthrough could lead to a whole range of new applications in the future.
