Penguins? How tasteless
Penguins may look all dressed up in tuxedo-wear, but their taste buds are the bare minimum. This means that the birds will never sense more than a hint of their meals’ true flavors.

Mice can teach us about human disease
Humans and mice look and act very differently. But 85 to 90 percent of their genes are the same or quite similar. So an international group of scientists is deciphering the instructions in mouse genes to help us better understand our own.

Air pollution can mess with our DNA
New research suggests a type of air pollution — diesel fumes — can affect your health. It inappropriately switches some genes on, while turning off others.

A whale of a lifespan
Bowhead whales can live more than 200 years. The secret to such longevity may lie in the Arctic species’ genes. Scientists recently mapped the whale’s genetic code. They found features that protect the marine mammal against cancer and other problems related to old age.

Virtual wounds: Computers probe healing
To better understand how the body heals wounds, scientists have begun creating computer programs that let virtual cells fight it out. These ‘computer games’ could lead to better medicines.

Learning rewires the brain
Brain cells actually change shape as we learn. It’s one way we cement new knowledge. And much of the action happens as we sleep.
