Pig hearts are about the same size as human hearts, which is why scientists used them to develop a battery-free pacemaker that generates energy as the heart beats. The discovery could lead to “implants for life.”
Scientists from Lawrence Livermore National Laboratory and other organizations have shown that human influences significantly impact the size of the seasonal cycle of temperature in the lowest layer of the atmosphere.
A creative new application for CRISPR is a platform to spur evolution of specific genes inside cells. “EvolvR,” lets scientists shake up the DNA letters in their gene of choice until they find the right variation.
