"Why are yawns contagious? We asked a scientist"
by Teresa Carey

Why do we yawn?

There is no scientific consensus on why we yawn. One theory argues that when humans are tired, we stop taking deep breaths, which causes a build-up of carbon dioxide in the body, said Douglas Parham, a speech scientist at Wichita State University. A yawn might be a special kind of respiration, Parham said. It builds up oxygen quickly, while expelling carbon dioxide, even more than a deep breath.

Excess carbon dioxide and other chemical changes, such as a drop in oxygen or increase in a compound called adenosine, could also act as “yawn gates,” said James Giordano, a neuroethicist and neuroscientist at Georgetown University. These chemicals send out a signal that triggers a yawn. By yawning, we compress the muscles of the face, driving oxygen-enriched blood to the brain, Giordano said.

Other proposals state the purpose of yawning is to cool the brain, or to stretch internal organs like tissues and lungs, helping the body to liven up.

A)

Question 5

"White Bias in Genetic Research May Hurt Health"
by Vicky Stein

Modern humans originated on the continent of Africa more than 300,000 years ago, and subsequent generations migrated across the land, with groups intermarrying or splitting apart. Sometime around 80,000 years ago, a small number of descendants left the continent and radiated around the globe, taking with them just a subset of the genes and genetic variation that their ancestors had developed.

Yet genetic studies are now dominated by that subset, according to a new article in Cell.

As of last year, 78 percent of the people included in the most prominent form of genomic research—genome-wide association studies (GWAS)—were of European ancestry. But worldwide, Europeans and their descendents make up just 12 percent of the population.

According to the researchers, heavily biased genetic databases could—and do—lead scientists and doctors to diagnose conditions or prescribe treatments that might be relevant to people with European genes, but not for people from other racial backgrounds.
