Using DNA Fingerprinting to Catch Poachers

Life Science Animals Engineering Genetics DNA

Game wardens in California are now using DNA fingerprinting analysis to help protect illegal poaching of wildlife. There are many species, from large game to shellfish, which are being illegally caught or killed for food. Since there are so few game wardens to patrol the state, they are relying on forensic evidence to help track poachers. Listen to learn about the latest in DNA fingerprinting technology.

Biomimicry and a Desert Beetle

Life Science Earth and Space Science Engineering Physical Science Ecology

To copy the way a desert beetle gets water, scientists have designed a membrane that can extract water from the air. Since all air contains water, even in the desert, this could provide a very inexpensive way to supply drinking water. This process is called “biomimicry,” or using ideas from nature to solve technological problems. This discovery could lead to reusable water bottles that refill themselves. Listen to learn why this invention would be inexpensive and how close scientists are coming to making it work.

Improving Battery Storage

Technology Engineering Physical Science Energy Electricity

Energy and how it converts to power is a never-ending exploration for scientists. The most significant issue concerning energy right now is how to store it, especially for long periods of time. It's possible to get solar energy from the sun, but what happens to the energy when it's not a sunny day? There's also the problem of having enough space to hold all of this energy. Listen to learn how scientists are trying to figure out how energy can be stored long-term to power the things we use every day.

Cap-and-Trade Carbon Emissions Policy Aimed at Using the Free Market

Earth and Space Science Climate Change Engineering

Cap and Trade is the new carbon emissions policy aimed at regulating emissions from various factories based on a "token" system. When an entity runs out of tokens, they can turn to the free market to buy more. This story clearly explains what Cap and Trade is and why Republicans don't like it.

Few Women in Engineering Due to Gender Gap

Gender Education Engineering

Olin College in Massachusetts has one of the largest student populations of female engineers, which is rare because so few women go into the sciences. There is a documented gender and confidence gap for female engineers, but students think it can be closed by reaching girls at an earlier age. Listen to this radio story to find out how schools are fixing this problem.
