Scientists are back — and ready to march
Supporters of science around the world will rally Saturday to send public officials a message that evidence-based policy decisions are important — and science cannot be ignored.

The first march happened last year, one month after President Trump signed an executive order aimed at rolling back Obama-era climate change and environmental policies.

No signature necessary: Checkout lanes should move more quickly
Major credit card companies Mastercard, Visa, American Express and Discover are eliminating the need for shoppers to sign receipts for credit and debit sales beginning April 14. That means most merchants in the U.S. or Canada can decide whether or not to gather signatures on sales using cards or mobile payments, but they aren't required to. Why?
