AI model to help scientists predict whether breast cancer will spread

Cancer specialists in Great Britain say they've developed an artificial intelligence model to help predict whether aggressive cancers will spread based on changes in a patient's lymph nodes. 

Researchers say the AI analyzes immune responses of women with triple negative breast cancer. They tested the model on more than 5,000 lymph nodes donated by roughly 350 patients. 

The team is planning more tests across Europe. 

Coffee makes workers feel more productive

A recent survey of 2,000 people shows workers feel like they need drinks in their work environment to be fully productive.

Eight in 10 people said free beverages at work helped them feel valued, and it was the most-requested perk to get workers to come back to an office setting.
