MELISSA BLOCK, HOST:

And I'm Melissa Block. Yesterday, President Obama sent out a tweet drawing attention to a study about climate change. The study found that scientists who say climate change is largely caused by human activities vastly outnumber the skeptics. NPR's Richard Harris has more on the study that caught the White House's attention.

The Illinois Senate has approved a measure to legalize the use of marijuana for medical purposes, sending the bill to the governor for his signature.

The bill would be the strictest in the nation. According to The Chicago Tribune:

When the diagnosis is cancer, the expenses can pile up in a hurry.

Even people with insurance can face steep copayments for drugs, a sizable share of hospital bills and significant incidentals. These side effects of cancer care are sometimes even called "financial toxicity."

So wouldn't it make sense for doctors and patients to talk over the financial strain that cancer treatment might bring and what might be done to manage it?

Flax is the oily seed usually spotted in the nutritional supplement or cereal aisles. It's marketed as a superfood because of its high levels of omega-3 fatty acids and fiber.

Omega-3s may do all kinds of good things for humans — like protect against Alzheimer's, heart disease and even cancer — so it seems reasonable to think they could also protect the health of animals.

Resetting the Theory of Time

Generations of physicists have claimed that time is an illusion. But not all agree. In his book Time Reborn: From the Crisis in Physics to the Future of the Universe, theoretical physicist Lee Smolin argues that time exists--and he says time is key to understanding the evolution of the universe.

When Great Scientists Got It Wrong

May 17, 2013

In Brilliant Blunders: From Darwin to Einstein, astrophysicist Mario Livio explores the colossal errors committed by scientific greats, from chemist Linus Pauling's botched model of DNA, to Charles Darwin's failure to understand genetics--the very mechanism of natural selection.

IRA FLATOW, HOST:

What's on your plate? What do you like to eat? What are you eating for lunch, dinner at this point? As with many things, the answer to that might have a lot to do with what you're accustomed to do and, you know, what part of the world you live in.
