How Your Body Responds to Stress

Life Science Health Psychology

Everyone has experienced stress, which is your body’s response to a demand made on it. A surge of hormones is released when people are stressed and that helps them deal with the danger or threat, but it also affects the nervous system and can cause health problems.

A Hero Bug Helps Scientists Develop Drugs

Life Science

Scientists have found a new bacteria in a cave 1,000 feet underground. The bacteria is resistant to 70% of antibiotics used to fight disease in humans. The fact that the bacteria is resistant to these antibiotics, despite never having been exposed to them, tells scientists that antibiotic resistance is genetically hardwired rather than developed as a result of exposure. Scientists are calling the bacteria a “hero bug” because it is not harmful to humans, and they hope that this new knowledge will lead to even more effective antibiotics. Listen to learn more about the “hero bug” and antibiotic resistance in bacteria.

School Napping Pods Help Reduce Stress

Health Education

Chronic stress and lack of sleep seem to be the new normal for American teens. Most teens are not getting the 9-10 hours of sleep a night that their bodies require.

These naps can boost memory and attention and help students perform throughout the day. Listen to learn more about the challenges facing modern teens and how nap pods can help.

Bed Bugs are an Expensive Pest Problem for Renters

Life Science KERA

An infestation of bed bugs is horrible, along with being costly to treat. They search for blood, mostly at night when people sleep, and their bites leave red welts and itchy skin. They spread easily and hide during the day, making them difficult to find. Getting rid of bed bugs is expensive and creates difficulties for low-income renters. Many tenants do not realize that their leases have sections that put the responsibility of getting rid of the bed bugs on them and not on their landlords.

Debate: Will a Textalyzer Improve Road Safety?

Technology Transportation

A new technology has been developed that could help law enforcement detect if a person has been texting while driving. Typically, in cases of auto accidents, law enforcement has to get an order from a court to look through a person’s phone records to see if they were texting at the wheel. This is a lengthy and difficult process that many believe slows the course of justice. However, the “textalyzer”, if used, would allow police to plug into a driver’s phone and quickly see their last 90 seconds of phone activity to determine if they were texting and driving. Listen to learn more about texting-while-driving bans and debate the benefits and challenges of using the textalyzer to improve safety.

Your Brain Gets Used to Lying

Life Science Psychology

A team of neuroscientists is working on studying how the brain reacts when we tell lies. What they found is that as one tells more lies, each progressive lie shows less brain activity associated with conscience or guilt. This means that being dishonest becomes easier overtime. However, facing negative consequences as a result of lying will cause the brain to react and discourage lying. Listen to learn more about the brain science behind lying.
