Threats To Freshwater Mussels And The Consequences

Paleo-anthropologists believe Homo sapiens evolved in Africa 100 - 200 thousand years ago, and eventually moved out of Africa to populate the globe. But, how can researchers trace the specifics of that ...

Threats To Freshwater Mussels And The Consequences For Ecosystems - Science Nation

Freshwater mussel species, with names such as 'fatmucket,' 'bankclimber,' and 'heelsplitter,' are critical to river ecosystems. But, many species are in trouble. Nearly 70 percent of freshwater mussel species are considered threatened in some way, according to zoologist Caryn Vaughn at the University of Oklahoma. With support from the National Science Foundation, Vaughn studies the role mussels play in freshwater ecosystems. If you can believe it, mussels live 30 to 50 years! And they work hard during that time, filtering ...

Teens And Stress - Science Nation

Ever wonder what is going on in the mind of a teenager, especially one who is stressed out? UCLA Psychologist Adriana Galvan is on a quest to find out. With support from the National Science Foundation, she's investigating the effects of daily stress on a teen's cognition and brain function. She is monitoring the daily stress of teens by having them carry a personal digital device that provides daily measures of stress over two weeks. She is also scanning their ...

Ticket To Ride - Science Nation

We've all been there. You've got a weekend trip coming up, just far enough away that you would like to fly, but when you check the rates the prices makes your eyes pop. And then you see a much cheaper rate for a city on the other side of the country. What's going on? With help from the National Science Foundation, economist Andrew Sweeting at Duke University is researching markets for perishable goods, which includes tickets because they have to ...

Human Migration : How Lice Can Shed Light On The Past - Science Nation

Paleo-anthropologists believe Homo sapiens evolved in Africa 100 - 200 thousand years ago, and eventually moved out of Africa to populate the globe. But, how can researchers trace the specifics of that human migration? With support from the National Science Foundation, Florida Museum of Natural History Mammologist David Reed has undertaken a novel approach. He studies the genetic diversity and evolution of the human parasite that hitched a ride the whole way: lice. He gathers samples from around the world. Over the ...

Developing Robots That Can Teach Humans - Science Nation

When it comes to communication, sometimes it's our body language that says the most - especially when it comes to our eyes. It turns out that gaze tells us all sorts of things about attention, about mental states, about roles in conversations, says Bilge Mutlu, a computer scientist at the University of Wisconsin-Madison. Mutlu knows a thing or two about the psychology of body language. He bills himself as a human-computer interaction specialist. Support from the National Science Foundation (NSF) ...

New Mosquito Repellent Could Be Frightening ... For The Mosquitoes! - Science Nation

Vanderbilt University researchers say they're working to unleash an insect repellent on mosquitoes that's more powerful than DEET. The discovery could one day be effective in reducing the spread of mosquito-borne diseases, such as malaria. It's based on a mosquito's sense of smell. With early support from the National Science Foundation, Vanderbilt University biologist Laurence Zwiebel researched which mosquito genes are linked to odor reception. Since then, he's discovered a separate odor sensor on a mosquito's antennae. According to Zwiebel, ...

Developing Hardier, Weather-resistant Crops - Science Nation

At first, the back room of plant physiologist Edgar Spalding's lab at the University of Wisconsin-Madison might be mistaken for an alien space ship set straight out of a Hollywood movie. It's a room bathed in low-red light with camera lenses pointing at strange looking entities encased in Petri dishes. A closer inspection reveals the Petri dishes contain nothing alien at all, but rather very down-to-earth corn seedlings. They're grown in red light for optimal growth. They're just one of ...
