Condor Comeback

Animals Human Impacts Biology Conservation

In order to prevent the California condor from going extinct, conservationists created a captive breeding program for the unique bird species. In the 1980s, they began gathering all the remaining California condors, breeding them, and releasing their offspring into the wild. Listen to learn more about “chick number 1000” and find out why one scientist thinks California condors are among the most remarkable birds in the world.

Debate: Should Elephants Be Considered Property?

Animals Ethics Reform Philosophy Biology

Should some animals be considered “persons”? One lawyer is working to classify certain animals as “persons” so they can be protected under the law. Specifically, the lawyer wants to send three elephants from the “Big E” fair in New England to a sanctuary, where they will no longer have to give rides to customers. The fair owner disagrees and wants to keep the animals. Listen to hear the arguments on both sides of this complex animal rights issue and then debate: Should elephants be considered property?

Puppy Dog Eyes

Psychology Animals Evolution Biology Diversity Neuroscience Adaptation

Has a dog ever given you “puppy eyes”? If so, you probably did whatever your furry friend wanted. According to a recent study, “puppy eyes” result from thousands of years of evolution impacted by the relationship between humans and dogs. This distinctive expression comes from a specific muscle and creates unique effects that help dogs become “man’s best friend.” Listen to learn more about why “puppy eyes” are so powerful and how studying dogs can help humans learn more about themselves.

Debate: Is Reducing Smoking Worth Increasing Nicotine Addiction?

Health Biology Development Neuroscience Human Anatomy

Researchers from the United Kingdom now have scientific evidence that using e-cigarettes is significantly more effective for quitting smoking than other methods. However, U.S. public health officials worry that promoting e-cigarettes could increase nicotine addiction. Listen to this story to hear about the research study findings and debate: Is reducing smoking worth increasing nicotine addiction?

Modifying Plant DNA with a Nano-Needle

Technology Engineering Genetics Plants Biology

Would you like to eat apples that never turn brown? Scientists hoping to genetically modify plants for crop development think they may have found a solution to a major problem they have been facing. The cell walls of plants make it difficult to insert genetic material into plant cells to change how those plant cells work. The solution–carbon nanotubes–was discovered by accident. Listen to learn about the discovery and implementation of this nanotechnology solution and how it could change the way scientists breed new crop varieties.

Measles Outbreak in the Pacific Northwest

Life Science Health Biology Human Body

The governor of Washington state has declared a state of emergency because of a recent measles outbreak. The majority of those sick from measles are children who were not vaccinated. Washington state has one of the lowest vaccination rates in the country. Measles is very contagious, and people who are not vaccinated are at high risk of catching the disease when exposed to it. Listen to hear more about the role vaccinations play in public health and what Washington is doing to contain this dangerous measles outbreak.

Hacking Photosynthesis

Life Science Genetics Nutrition DNA Biotechnology Plants Biology

Photosynthesis is the process that is foundationational for all life, in which plants use sunlight to change water and carbon dioxide into food and oxygen. Scientists have now genetically modified plants to perform that process more efficiently, thereby increasing agricultural productivity. Listen to this story to learn how researchers “hacked photosynthesis” and why it matters.

How the Brain Stores Phone Numbers

Life Science Biology Human Body Anatomy

How do you remember a phone number? At a recent neuroscience conference, brain scientists found themselves debating this surprisingly difficult question. Storing a phone number turns out to be a complex working memory task with broader implications for how the brain works. Listen to this story to hear two different theories about how working memory operates and why understanding this basic function matters.

Debate: Should Humans Be Genetically Modified?

Ethics Genetics Biotechnology Biology

A Chinese scientist claims to have created genetically edited human babies, igniting a major ethical controversy. The scientist says he used a new genetic engineering technique to modify genes in human embryos to resist HIV infection and then created twin girls from those embryos. His claim has yet to be verified. The scientific community has responded with strong ethical concerns about the risks of this type of human experimentation. Listen to this story to learn more and then debate: Should humans be genetically modified?

Tiny Plastics Everywhere

Life Science Ecology Biology

When plastic is thrown away, it crumbles into tiny pieces, known as microplastics. These small bits of plastic, less than 5 millimeters (or 0.2 inches) in size, are polluting rivers, lakes, oceans, and even soil. Scientists are studying how microplastics find their way into the ecosystem and what happens when they do. Listen to hear what research ecologists are doing to learn more about how microplastic waste may be affecting us and our world.
