An estimated 1 in 13 children have food allergies. Some are potentially life-threatening and avoiding the allergen can be challenging and stressful. The blood tests and skin prick tests rule out specific food allergies but are not as accurate when confirming food allergies. The oral food challenge, where the food is eaten under the supervision of a doctor has become the gold-standard for determining allergies. Listen to this story about allergies as a health concern and the best way to tell if the food allergies have been outgrown.

American doctors rely on clinical trials to determine which drugs to use in treatment. Researchers have found that clinical trials have not been effective in creating drugs for America’s diverse population. When clinical trials are too homogeneous, they can leave important discoveries undiscovered. Patients who are diverse ethnically and racially can respond differently to medications, leading to dire consequences. Listen to learn how a lack of diversity in clinical trials affects patients and how researchers are trying to fix it.

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. When we experience a lot of stress, our bodies don’t easily return to a relaxed state. Listen to hear more about what stress does to our bodies and what we can do about the impact of stress.

The sounds of male elephant seals are different and each has a unique rhythm. A new study suggests that alpha males are recognized by their calls during mating season. If other males hear the call, they will scatter. An elephant seal’s call is loud and is also used to signal who they are. Males have unique rhythms and females have calls to threaten and calls to their pups. Listen to hear more about the new discoveries about what the calls of elephant seals mean.

We live in an age when genetic engineering has the capacity to affect the course of human evolution. Scientists can edit human DNA, which could have profound benefits for society, but they also come with dangers. Editing human DNA can allow for the treatment and prevention of disease, but edited DNA can also be passed down from generation to generation, becoming a permanent part of human genes. The scientific community met to discuss these issues and clearly stated that creating a baby with edited DNA is dangerous and unsafe, but supported the basic research to see what is possible before taking any next steps. Listen to hear more about this issue and what scientists have concluded.

Animals with long limbs and lots of muscle should be faster than other animals. In reality, even though a giraffe has much longer legs than a cheetah, it runs only about half as fast. This is because there are other factors involved in acceleration and speed of animals, such as how much energy they have to burn. Listen to learn about how new research on animal speeds can give scientists clues about the lives of prehistoric animals.
