However, the explanation for this observation has been a topic of controversy. Does sport cause heart enlargement, or are individuals who succeed at sport simply born with bigger, perhaps more capable hearts? Hear Dr. Aaron Baggish describe collaborative work between the Massachusetts General Hospital's Cardiology Division and the Harvard University Department of Athletics that is beginning to answer this question.

Researchers have recently announced that they have fabricated the world's largest single sheet of graphene, a derivative of the more familiar graphite found in pencils. The Museum's Tim Miller discusses this potentially revolutionary new material.

His team discovered that people in both populations were far more likely to be diagnosed with asthma if they were born in the United States than if they were born in another country. Why might this be? Hear Dr. Brugge's explanation in this segment.

Researchers at Yale University and the National Institute of Standards and Technology (NIST) have developed a computer model that accurately reproduces measured cell output from electric eels. Using this model, they discovered the potential for cells with a higher and more efficient energy output. Their research suggests the possibility of synthetically engineering these improved cells as an organic power source for medical devices, fueled by energy from fats and sugars in the food we eat.

Could purple tomatoes be on your dinner plate one day? In this videocast, hear how researchers at the John Innes Centre in England have genetically engineered a tomato plant to produce purple-colored fruit. The tomatoes have high levels of anthocyanins, which are naturally occurring pigments that give many fruits and vegetables their purple, red, and blue coloring.
