Is there a link between wildfire smoke and lung cancer? According to health care experts, exposure to the ash, dust, and soot in wildfire smoke can have a negative impact on health that is similar to exposure from diesel exhaust or smoke from cigarettes.

As Benji Jones explains for Vox's "Down to Earth," scientists are going to great lengths to, basically, attach EKG sensors to these massive animals. Besides the secrets of whale biology and beaching threats it may unlock, it also means that you can now fall asleep to the soothing sounds of a whale heartbeat.
