Using artificial intelligence, a Stanford-led research team has slashed battery testing times – a key barrier to longer-lasting, faster-charging batteries for electric vehicles – by nearly fifteenfold.

In regions that lack the resources to treat the contaminated water, it can lead to disease, cancer and even death.
