Even though repetition and memorization have fallen out of favor in many schools, one scholar argues that those, not active discussion or creative approaches, are the most effective ways for students to learn math.
Neuroscientists studied the brain of free solo climber Alex Honnold and discovered that he doesn’t experience fear like the rest of us.
The story of the scientists who try to predict earthquakes – and why their quixotic quest might never succeed.
By studying how moral behavior works in the real world, scientists are tackling an ancient subject that was previously the domain of religion and philosophy: whether human beings are inherently cooperative or competitive. In other words: how selfish are we? The news is good.
A photographer’s quest to document the world’s oldest living plants makes her reflect on the tricky relationship between art and science.
For 25 years, Kai Brothers, who is HIV positive, has been studied by AIDS researchers because he has been healthy and has never taken HIV drugs. Brothers now faces a vexing choice—a dilemma that mirrors a quandary for modern medicine.
Engineer Joshua Pearce explains how to feed 7 billion people after a global catastrophe. Hint: get ready to eat some bugs.
A look at how identical twins—and Olympic gold medalists—Mike and Bob Bryan communicate with each other, as well a larger discussion of “cryptophasia” or the shared language between twins.
Following the fossil hunters in Ethiopia who are searching for the origins of humanity.
Scientists are conducting experiments to learn what might happen if we went back in time and life started over again:
Rather than attempt to reconstruct history with fossils, Richard Lenski, an evolutionary biologist at Michigan State University, decided to watch convergence and contingency unfold in real time, in the controlled environment of his laboratory. In 1988, he separated a single population of Escherichia coli bacteria into 12 separate flasks containing liquid nutrients, and let them each evolve separately. Every few months for the past 26 years, he or one of his students has frozen a sample of the bacteria. This archive of frozen microbes gives Lenski the ability to replay E. coli’s tape of life from any point he wishes, simply by thawing out the samples. Along the way, he can examine how the bacteria change both genetically and in ways that are visible under a microscope. Lenski says, “The whole experiment was set up to test how reproducible evolution was.”
