Uncovering the Unknown: How Old Discoveries Became New

Wood Samples Collected 100 Years Ago Helped Modern Science in Unexpected Ways

by Vanessa Shell, age 12

In 1901, astronomer A. E. Douglas had an idea about how to study the effect of sunspot cycles on the Earth. Little did he know that this very idea would ultimately lead to some important discoveries.

How did Douglas develop this idea in the first place? Simple: he cut down a tree, measured it with calipers, and looked at its growth rings. A tree's rings give an invisible record of the conditions during and the time at which the tree lived. In fact, anything made out of wood gives a record of the conditions during its existence.

Teen Brains Wired Differently

But Young People Can Still Make Wise Decisions When They Make Time to Think About Choices

by Je’Niya Adams, age 13

Teenagers today are known for their irritable, impulsive behavior and constant craving of gratification. Teen minds are wired to be impatient. But why?

Researchers at Max-Planck Institute for Human Development in Germany recently published findings that suggest teens’ misbehavior is due to incomplete development of the decision making machinery in their brains. The amygdala is the emotional center of the brain. Teens' amygdalas are not completely developed so, teens are not as equipped as adults to envision the consequences of their actions. [Read More]

Quasars: The Most Energetic Objects in the Universe

by Cristian Avila-Velazquez, age 13

Quasars are huge, energetic, mysterious objects in space. Modern technology has allowed humans to understand these objects better.

Quasars create a massive amount of light, allowing them to be seen from great distances. The farthest quasar from Earth is located 12 billion light years away in the middle of young galaxies. At the center of a quasar is a huge, spinning black hole. The black hole creates massive amounts of energy. It’s so massive that the average size of a black hole can be one billion times larger than the sun! [Read More]

Pesky Pythons Remain Unchecked in Florida

Government Efforts to Contain the Invasive
Species Remain Unsuccessful

by Mario Rea-García, age 12

The Burmese python is an invasive species currently causing severe problems in Florida. In recent years, the U.S. Fish and Wildlife Service and many other organizations have spent more than six million dollars trying to find a solution to curb this problem.

Burmese pythons are a species of constrictor snake native to the subtropics of South and Southeast Asia. The Burmese python has green and brown skin that camouflages easily. The python can grow up to 18.8 feet, which puts it among the top five largest snakes in the world. This tremendously big snake can thrive in a range of different environments since it both swims and climbs trees. [Read More]

Carbon: Every Girl’s
Future Best Friend

by Leila Fletcher, age 14

The element carbon is one of the most abundant elements on Earth. People have known about its existence since ancient times, and it still has many uses today.

Carbon’s symbol is “C,” and its name comes from the Latin word for charcoal: carbo. Its atomic number is six, which means that carbon has six protons and six electrons, and it has an atomic mass of 12.0107. The element’s electron configuration is 1s2 2s2 2p2. At room temperature, carbon is in a solid phase, and it melts at 6422 degrees Fahrenheit. [Read More]

No One Knows For Sure Where the Lead Pipes Are

by Deney Li, age 15

Since the water crisis in Flint, Michigan, the issue of lead-contaminated water and lead pipes has gained renewed attention. Since then, many states, including Wisconsin, have taken action to replace the lead water pipes still in use by schools, homes, businesses and other facilities.

What makes this task difficult is that regulatory agencies, like the Public Service Commission (PSC), do not have a clear record of where lead pipes are located in the state. Utility companies may have a hodgepodge collection of papers and records, but the information has never been collected or analyzed. This is probably because local officials did not have a reason to document piping systems until Congress banned the installation of new lead pipes in 1986—although some cities banned their use even as early as the late 1800’s. Today, lead is known to stunt development of the nervous system in young children and infants. [Read More]
