How Our Brains Recognize Words

Physical Science Human body

Scientists have identified a two-step process that helps our brains learn to first recognize, then categorize new sounds, even when they sound almost the same. This process is similar to how the brain processes visual information. The research team used monkey calls in their experiment and taught volunteers to recognize them. Then the volunteers’ brains were studied. Listen to hear more about this discovery about sounds and what the new studies may help us understand.

Cow Burping and Greenhouse Gases

conservation

Greenhouse gases trap heat in Earth’s atmosphere, contributing to climate change. One of the most common greenhouse gases is methane. In the United States, cars and industry are the primary sources of greenhouse gases. In Africa, which has more agriculture than industry, burping cows are the main producers of methane gas. Researchers have found that African and American cows are actually quite different from each other in the amount of methane in their burps.

Offshore Wind Energy and Fishermen

Environment

Offshore wind can be a big business, and property that is windy with shallow water is perfect for installing and maintaining wind turbines. The federal government has leased sites for developers to build industrial-scale wind farms over the next decade. The area of New Bedford, Massachusetts, which is close to Rhode Island and New York, is an area with a sustainable wind source. The developers are very engaged with fishermen in the area, since the spinning blades confuse the instruments they use to navigate through fog. By working together, turbines can be put in locations that won’t interfere with fishermen’s routes. Listen to hear more about offshore wind projects in this area.
