Host Kevin Patton outlines several new discoveries, including the function of background noise in the brain, how exercise triggers immunity, a possible blood marker for longevity, and how mitochondria are organized during cell division. And he discusses how easy animation effects can help students focus on important elements of the story of anatomy and physiology.

Brain's Background Noise
7 minutes
The so-called "background noise" in an electroencephalogram (EEG)—that aperiodic data that contrasts with the periodic waves we usually look for—may be a measure of consciousness.

How Exercise Triggers Immunity
4 minutes
We know that exercise has many beneficial effects in the body, including stimulation of the immune system. A new discovery in mice suggests that the same pressure that triggers bone growth with exercise also triggers the precursors to lymphocytes in bone marrow.

The Master of Science in Human Anatomy & Physiology Instruction—the MS-HAPI—is a graduate program for A&P teachers, especially for those who already have a graduate/professional degree. A combination of science courses (enough to qualify you to teach at the college level) and courses in contemporary instructional practice, this program helps you be your best in both on-campus and remote teaching. Kevin Patton is a faculty member in this program. Check it out!
Mitochondria During Cell Division
7.5 minutes
We know how the nuclear genome is organized into two equivalent groups during cell division—at least the broad strokes. A new discovery sheds light on complex mechanisms that distribute the mitochondrial genome.

How Old Will We Get?
3 minutes
A study of 90- to 100-year-olds suggests that there's a blood marker that might give clues to our longevity.

Focus our Story on Slides
9 minutes
It's best to have few, if any, phrases of text on our teaching slides—so that students will focus on our orally presented story of anatomy and physiology. But when we do need more than a phrase or two—a term or two—then using simple animations to bring them in one at a time works well.

The Scoop About Segments
1 minute
Chunking. I use segments to divide the episode partly to give room for sponsor messages (thank you, sponsors!), but also to chunk the content so that it doesn't feel like you are drinking from a fire house. You know?... a bit of a cognitive "breather" before moving on to the next thing.

Smooth Slides for a Smooth Story
7.5 minutes
Smooth and subtle animations for bringing in new slide elements work better that jarring "appear" animations or wildly sliding or jumping or scrolling animations. This is especially important when considering accessibility for those with motion-sensitive conditions. Smooth... that should be our mantra!
