Students will investigate how researchers apply chemistry principles to create a potential solution to help diabetes patients. Students will define the problem of why it’s difficult to create skin patches to deliver diabetes drugs and brainstorm possible solutions by thinking about the structure and function of the different layers of the epidermis.

Universities that opened their campuses in fall 2021, during the COVID-19 pandemic, faced an uncharted, months-long experiment in infection control. Science News looked at the measures five universities took. Each school cobbled together periodic testing with rules about masks and public gatherings.

For 3,000 years, humans have connected emotions to some of the same body parts. An analysis of clay tablets reveals that ancient Mesopotamians felt love in the heart and fear in the gut, as we do today.

In this activity, students will design an experiment to observe how exercise affects their ability to concentrate in class. Students will then read the Science News Explores article “Short exercise workouts can boost classroom performance” and analyze how their experiment differed from the experiment described in the article.

The ancient Incas used a system of knotted strings — called khipus — for recordkeeping. Learn how carbon chemistry can offer clues about the diet and social status of an ancient Incan individual. You can also carry out calculations to determine average annual growth rates based on information from the story.

Protein is having a moment. It’s cropping up as an additive in all sorts of foods, and social media influencers tout high-protein diets as key to big muscles. But people in the United States typically get enough protein; they just might not be getting the right mix.

Cancer is typically a disease of older people. But since the 1990s, rates of early onset cancer have been rapidly increasing globally.

Brain scans can help scientists answer questions about how the brain receives information from parts of the body and controls them. In this short activity, students will think of a question that could potentially be answered by brain scans and write a scientific question.

Walking just 7,000 steps per day can lower a person’s risk of certain health issues, according to a new study. Even a small increase in steps per day lowered health risks.

Contraceptive pills for women emerged in 1960, followed by hormonal implants, patches, vaginal rings and IUDs. But no new contraceptive methods have become available for men. New research could change that in the next five to 10 years.

Scientists predict that, by 2060, one million U.S. adults per year will develop dementia. The new estimate surpasses previous estimates of how many people will struggle with memory, reasoning and language difficulties that interfere with life.

Three types of ticks may spread alpha-gal syndrome, an allergy to red meat. Researchers think the condition is caused by molecules in the saliva of certain tick species. The best way to avoid the syndrome is to prevent tick bites.
