A team of scientists from Columbia University, Arizona State University, the University of Michigan, and the California Institute of Technology (Caltech) have programmed an autonomous molecular “robot” made out of DNA to start, move, turn, and stop while following a DNA track. The molecular robot, nicknamed “spider”, shows the potential for the development of molecular-scale… »

Fusion has been a cherished goal of physicists and energy researchers for more than 50 years, since it offers the possibility of nearly endless supplies of energy with no carbon emissions and far less radioactive waste than that produced by today’s nuclear plants. A new experiment that reproduces the magnetic fields of the Earth and… »
