2017 Nobel Prize Winners in Medicine

Life Science Human body

The Nobel Prize is a set of annual international awards given to people who make outstanding contributions in the areas of science, culture, or academics. This year the Nobel Prize in physiology or medicine was given to three U.S. scientists for their discoveries about how internal body clocks govern human biology. Our daily rhythms, our sleep and awake cycles, are related to the cycles of the sun. We typically get tired in the evening and feel awake during the day. Listen to hear more about this discovery about how our internal clocks work.

Sleeping and Eating

Life Science Psychology Human body

When we don’t get enough sleep, we often find ourselves eating more. Researchers at the University of Chicago recently published a study that helps explain why. Their experiment showed that sleep deprivation causes an increase in endocannabinoids, which are compounds in our brain. Listen to learn more about how sleep deprivation can lead to overeating.

Does Lack of Sleep Keep People Poor?

Life Science Human body Learning

Hundreds of people sleep by the side of noisy roads typical in India’s largest cities. The same is true in other low-income countries. Researchers are now looking at whether or not a lack of sleep may actually be a root cause of poverty. Researchers are studying the real-world impact of chronic sleep deprivation, and the impact on how people make, and avoid, decisions. When people are tired, they don’t have the mental capacity to deal with some decisions and that can keep them from making good choices. Listen to hear more about how lack of sleep can affect learning and brain functions.

You've Got Face Mites

biology Human body Human origins

Tiny, 8-legged creatures are crawling all over your face. This isn’t a scene from a horror movie. This is a fact. We’ve all got mites on our face and we have probably had them since before we were human. Occasionally, face mites are linked with skin issues, but they are mostly harmless. By studying these microscopic creatures, scientists can learn a lot about evolution. These mites travel with us through generations and can help trace our origins. Listen to this story to hear more about what can be learned from studying face mites.

Bones Tell Stories

Life Science Human body

When skeletons turn up, a lot of information can be found in the bones. Knowing how to read the bones is the job of a forensic scientist. Bones can help identify missing persons, solve a murder case, or help medical research. In the Bass Donated Skeletal Collection in Tennessee, there are thousands of donated skeletons that serve as silent teachers. People come from all over the world to study these bones and learn from the information hidden in them.

Fish Fossil Gives Clues to Evolution

Life Science Animals Evolution Human body

Animal species evolve and adapt over time. This ability to change lays the groundwork for human evolution. Over 375 million years ago an important transition in this lineage occurred - animals living in the sea, began living on land. This complex process happened gradually over generations and an unusual fish fossil found in the Canadian Arctic may help enhance our understanding of this progression.

Inventor of Polarizing Microscope Sheds Light on Cell's Mystery

Life Science Engineering Genetics DNA Human body Cells

A new way of looking at live cells is revolutionizing our understanding of how molecular life works. However, it is how how one scientist managed to complete his study despite facing World War II in Japan that makes his discovery so intriguing. By using an old machine gun, Shinya Inoue made a microscope that enabled him to start to see how a cell divides. Listen to learn how Inoue finished his microscope and why it is so important to the science community.

Losing Weight While You Sleep

Life Science Health Nutrition Mathematics Human body

People lose weight when sleeping, and much of that weight loss comes from merely breathing. Through a process of matter being recycled along with sweating while sleeping, people lose weight. However, the atoms and molecules involved are so small that it is hard to believe they are so powerful in this process. Listen to learn how this cycle works.

Earth and Space Science Health Climate Change Weather and Climate Human body

Global warming is expected to increase summer temperatures making cities even hotter. As concrete and asphalt within cities retain heat, it can increase health risks. The sun mixes with city pollution to create ozone that can irritate people's lungs, especially if they have breathing problems such as asthma. Listen to learn how public health officials are trying to help those living in the hottest areas.

Microbes are Still a Mystery to Scientists and the Diversity of Life

Life Science Genetics DNA Human body Cells

The study of genes is moving toward a new frontier. There is a new field studying microorganisms which exist in living organisms. Microbes control every process on earth, and a human is made up of 90% bacteria. However, we know very little about these microbes. There is now a newer, more efficient way, to study this bacteria. From this scientists can discover new species and genes. Listen to learn how the study of microorganisms became so important.

Preventing Cancer at a Cellular Level

Life Science Health Genetics Human body Cells

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.
