The United States is one of only a handful of countries that doesn't use the metric system. Most of the world calculates distances in meters. The creation of the meter in 1792 was based on the need to agree on a uniform system of measurement. But the first time scientists tried to determine the length of a meter, they made some mistakes. Listen to this public radio story to learn why accuracy is necessary.

The Center for Disease Control (CDC) recently lost track of dangerous samples of anthrax and the flu. Investigation into lab safety shows a breach of protocol, especially since scientists continue to experiment with more dangerous types of viruses. Listen to this public radio story to learn why lab safety is important.

You can tell a lot from a tiger’s roar. A researcher in Texas is using the sound of tigers’ vocalizations to track and protect them in national parks and in the wild around the world. By monitoring tigers acoustically, researchers can track their location and know whether a tiger is a male or female, its weight, and other characteristics. Listen to learn why this project is helping tigers in captivity and in the wild.

More money is spent on treating cancer than preventing it within the United States. However, scientists are getting closer to finding out if cell growth within our bodies promotes already existing cancer. Scientists are examining microscopic cells to test if certain spices and foods affect the reduction of cell growth. Listen to learn about the budget behind cancer research and how human behavior can increase the chance of cancer.

Trees can stand up to 100-mile an hour winds during strong hurricanes. Why do some trees survive and others don’t? The answer may be in a mathematical pattern in tree growth—first observed by Leonardo da Vinci. The rule states that smaller tree branches have a precise, mathematical relationship to the branch they came from. A scientist that is studying how air flows around objects is also studying this pattern in tree branches and looking for an explanation. Listen to hear more about these observations about trees and mathematics in nature.

The disease smallpox was successfully eliminated in 1977, but two research facilities still hold the last samples of the smallpox virus. The World Health Organization is going to vote soon on the future of the smallpox samples. Should we keep the virus to study it or completely destroy it because it could get into the wrong hands? Listen to this story and discuss.

A recent report by the U.S. government shows the most definitive evidence so far that climate change is happening and it’s being driven by people. Extreme weather and rising sea levels are just some of the consequences. Communities are trying to build preventative infrastructure, but it is costly.
Current Event May 16, 2014
Climate change will not only create extreme weather, but scientists have found that areas with more carbon dioxide grow less healthy crops. Although these crops are much larger in size, they lack nutrients such as zinc and iron. Listen to these findings on the long-term impact of CO2 on crops.
Current Event June 23, 2014
A new research article has ruffled the feathers of some scientists. The study questions whether it’s damaging endangered populations of birds and other species to collect them for scientific study. Many scientists see the collection of rare animals as a way to discover diseases and understand the past, while some ethicists see collection as a threat to small endangered animal populations. Listen to this audio story to learn more.

Animal manure creates the necessary nutrients, phosphorous and nitrogen, to help plants grow. However, water sources surrounding animal farms are also heavily polluted, mainly due to phosphorous in the water beds. Find out how farmers are trying to be economic about the environment.

The remains of hunter-gatherers were found in a cave dating back 12,000 to 15,000 years ago. These people did not grow food, but rather, foraged for it. What interests scientists is that the hunter-gatherers were found with cavities, despite the “paleo diet.” Listen to this story to learn the culprit of cavities.
