Scientists published the first hearing tests on a wild population of healthy marine mammals. The tests on beluga whales in Bristol Bay, Alaska, revealed that the whales have sensitive hearing abilities and the number of animals that experienced extensive hearing losses was far less than what scientists had anticipated.

The latter findings contrasted with expectations from...

Human immune response in the fruit fly

Washington State University researchers have seen how both humans and fruit flies deploy a protein that plays a critical role in their immune responses to invading bacteria. The discovery gives scientists a model organism with which to explore ways to boost the human immune system and create infection-fighting medicines.

Naturally, there are enormous differences between humans...
