Fish teeth mark periods of evolution
Based on close examination of thousands of fossilized fish teeth, a Harvard researcher found that, while the asteroid impact that killed off the dinosaurs did lead to the extinction of some fish species, it also set the stage for two periods of rapid evolution among marine life.

All goes swimmingly
Using simple hydrodynamics, a team of Harvard researchers was able to show that a handful of principles govern how virtually every animal — from the tiniest fish to birds to the largest whales — propel themselves through the water.

How fish swim
Scientists have long believed that sunfish, perch, trout, and other such bony fish propel themselves forward with the movement of their tails, while their dorsal and anal fins — the fins on their tops and bottoms — work primarily as stabilizers.

Benefits of eating fish tip the scale
In a new, large-scale study from Harvard School of Public Health and Brigham and Women’s Hospital, researchers found no evidence that higher levels of mercury exposure were associated with higher risk of coronary heart disease, stroke, or total cardiovascular disease in two separate studies of U.S. adults.

Volumetric Imaging of Fish Locomotion
Using a new form of laser imaging device, Brooke Flammang and colleagues at Harvard’s Museum of Comparative Zoology have discovered that “the dorsal and the anal fin make a great contribution to the caudal [tail fin] wake,” and thus are additional propellers, and not just stabilizers. A cichlid swims in the particles that the laser…

Teen diets can hurt their lungs
For most teenagers in the United States and Canada, fish and fruit are not high on their delicious list. Also, many of them — about 20 percent of those under 18 — cough, wheeze, and suffer from asthma and bronchitis. Researchers at the Harvard School of Public Health (HSPH) have found a connection between these…

When fish first started biting
Before fish began to invade land, about 365 million years ago, they had some big problems to solve. They needed to come up with new ways to move, breathe, and eat.
