The tantalizing aroma of freshly baked brioche is hard to resist, while a virtuous loaf of whole wheat often lacks that same allure. Blame it on the ferulic acid.
See, whole-wheat bread contains all parts of the wheat, including the bran, but white bread does not. That bran in the wheat bread contains the aforementioned ferulic acid, which overrides the compounds that give white bread its mouthwatering smell, according to new research.

David Bowie released a new single this week. The song may be new, but it sounds old. It sounds familiar. Like a David Bowie song. It sounds new and familiar at the same time. This is what makes it so good, I think. (It also has the wonderful lyric: "The moment we know we know we know.")
This got me thinking about the fact that music has a history. This is puzzling. Why should music have a history?
According to the EPA, more than 2.5 million tons of electronic waste, or e-waste, is produced each year in the U.S. Derek Markham, a contributing writer for Treehugger.com, discusses the global impacts, and why you should think twice before discarding your old cell phone.
What's it like to live--and cook--on Mars? To find out, researchers are simulating Mars missions in Russia, and on the slopes of a Hawaiian volcano. Kim Binsted talks about her study to whip up tastier space food. Porcini mushroom risotto, anyone? And sleep expert Charles Czeisler talks about how humans adapt to the 24.65-hour Martian day.
Next up, yet another way that genetics is giving rise to new ways to treat cancer. A few months ago I was at a conference focusing on individualized medicine; that's treating people individually, using medicines that were designed for each person's genetic makeup. It's a new frontier that we'll be talking about more.
This is SCIENCE FRIDAY. I'm Ira Flatow. This isn't going to take you by surprise, but America is fat. One in three adults is obese. For kids, it's one in six. But don't forget the infants. Doctors say there's now an obesity epidemic among six-month-old babies. And if you think you're safe because you're thin, consider that up to 40 percent of thin people have metabolic syndrome, in other words, on the road to type 2 diabetes, even if they can't tell by looking in the mirror.
This is SCIENCE FRIDAY, I'm Ira Flatow. Pap tests are routinely used to screen women for signs of cervical cancer, but now researchers from Johns Hopkins University in Baltimore say the tests might be able to detect ovarian and uterine cancers as well.
It's hard to imagine how this teeny little rock — it's not even a whole rock, it's just a grain, a miniscule droplet of mineral barely the thickness of a human hair — could rewrite the history of our planet. But that's what seems to be happening.
