Antarctica Is Melting: 3 New Discoveries About the Melt

Antarctica is melting, but why is that so consequential for the climate everywhere else on Earth? Would cutting emissions now help the situation? Changes that occur in Antarctica have planet-wide effects because the continent helps regulate the global climate. With the sea ice at its lowest peak since records began, some scientists are beginning to worry. Keep reading for a look at the three new discoveries about the loss of ice in Antarctica.

Are We in an Ice Age? Here’s What Scientists Say

What was North America like during the ice age? When did the last ice age end? Could we still be in one right now? Our human ancestors lived through the ice age, when a third of North America was covered by ice and woolly mammoths wandered the Earth. But, believe it or not, we’re technically still living in an ice age now. Here’s what living in an ice age is really like and what might come next for Earth’s climate.

Time Is the Fourth Dimension: How H.G. Wells Explained It

How did H.G. Wells explain time and time travel in The Time Machine? Did he get it right, according to real science? A Victorian scientist builds a machine that can travel through time. The Time Machine, first published in 1895, is one of the earliest known science fiction stories. This literary classic by English author H.G. Wells popularized the concept of time travel and introduced the now-common phrase “time machine.” Read more to learn how the book explains that time is the fourth dimension.

Lies in Science: How a Focus on P-Values Leads to Bullshit

Is the institution of science immune from misinformation? How can there be lies in science when practitioners are committed to the scientific method? In Calling Bullshit, Carl T. Bergstrom and Jevin D. West argue that science’s focus on statistical significance gives rise to bullshit for two reasons: we can easily misinterpret what statistical significance means, and we’re exposed to statistically significant findings only because of publication bias. Let’s take a close look at both of these problematic dynamics in science.

Bullshit: The Problem With Big Data You Should Know About

What’s big data? How helpful is training data? What can make it problematic? Professors Carl T. Bergstrom and Jevin D. West are so concerned about misinformation that they wrote a book about it. In Calling Bullshit, they argue that big data can foster bullshit because it can incorporate poor training data and find illusory connections by chance. Continue reading to learn about a problem with big data that should have everyone’s attention.

The 3 Stages of Learning a Skill—and the Science Behind It

What’s going on in your brain when you learn a skill? What stages do you go through? According to neuroscience research, you can improve any skill through practice because your brain is designed to learn and grow. During the skill acquisition process, you progress through the phases of cognition, association, and autonomy. Keep reading to understand these stages of learning a skill and the science that makes this growth possible.

What Is Aging in Humans? Definitions and Disproved Myths

What is aging in humans? What are common myths about aging? Though we all know on a basic level what “aging” is, scientists often use common terms differently than the general public. In Ageless, Andrew Steele defines aging and explores common myths that prevent laypeople and scientists alike from understanding aging as a process we can modify. Let’s look at the definition of aging, according to Steele and other experts.

The Causes of Aging: 3 Processes That Deteriorate Health

What are the causes of aging? What systems in the body speed up the aging process? In Ageless, Andrew Steele writes that many biological processes cause the symptoms of aging. To figure out how aging happens, scientists need to understand these processes. Keep reading to learn about the processes that contribute to aging and what science is doing about them.
