No need to be stingy with spices. Research from Penn State finds heavily spiced meals — think chicken curry with lots of turmeric, or desserts rich in cinnamon and cloves — may do the heart good.

"Elevated triglycerides are a risk factor for heart disease," explains researcher Sheila West.

Her study found that a spicy meal helps cut levels of triglycerides, a type of fat, in the blood — even when the meal is rich in oily sauces and high in fat.

Here's another good reason to lose weight: It might benefit your friends, family and co-workers. Such altruism might be just the final "nudge" some of us need.

Researchers are finding that the friends and family of obese and overweight individuals who lose weight lost weight themselves, and sometimes a lot of it. Dr. John Morton, who directs Bariatric Surgery at Stanford Hospital & Clinics, calls obesity a "family disease."

The National Academy of Engineering in Washington, D.C., once asked its members to pick the greatest engineering achievement ever.

Their choice? The electrification of the country through what's known as "the grid."

Ernest Moniz, director of the Energy Institute at MIT, says they were right on the money.

"That reflects what an amazing machine this is, spread out geographically, always having to balance demand and supply because electricity is not stored," he says.

There's a man in Phoenix with a political playbook that has become valuable. So valuable, the Obama campaign believes it could help clinch the president's re-election.

Phoenix City Council Member Daniel Valenzuela is a fourth-generation Mexican-American. Last year, he won a seat on the Phoenix City Council in a traditionally Republican district, and he did it by increasing Latino voter turnout by 488 percent.
