In the summer of 1930, a young radio engineer by the name of Karl Jansky developed new technology that opened the heavens for observation far beyond what had been possible previously. This was the birth of radio astronomy. […]
Drug overdose deaths have skyrocketed in the United States over the last few decades, creating what we now know as the opioid crisis. For example, in 1968, a little over 5,000 people died from a drug overdose in the US. In 1990, that number had grown to about 8400. But why are opioids, like fentanyl, so dangerous? […]
Pseudoscience goes beyond just making a few errors or a few sloppy practices—the methods are so flawed that the entire endeavor is suspect. They have the patina of legitimate science, but something has gone terribly wrong. […]
What’s the truth behind the claim that artists and scientists are “right brained” thinkers? Does tapping into your right hemisphere make you more creative? […]
Roger Sperry, together with his student Michael Gazzaniga, participated in pioneering experiments, which won Sperry the Nobel Prize in 1981, and helped make Michael Gazzaniga the father of cognitive neuroscience. But their experiments also seeded one of the biggest brain myths out there: That “left-brained people are logical and “right-brained” people are creative. […]
The murder of Mary Kelly apparently ended the killer’s rampage, at least in the London Whitechapel area. No one knows to this day who he was or why the murders ended. Did he die? Was he incarcerated for something else? Did he wind up in a mental institution? Did he move away? Despite thousands of books written on the subject and countless articles espousing different theories and possible suspects—over 125 years of analysis—his identity is not known. […]
The first widely reported “serial killer” investigation shows us early forensic science at work, how authorities linked the killings back to one murderer, and which police procedurals were established to find the assassin. […]
At the dawn of World War II, people saw the prospect of atomic war so remote as to be meaningless. The Manhattan Project would change those views forever. […]
The unifying theories of physics are among the greatest and most complex in all of science; they stand as incomparable masterpieces in the gallery of modern thought. As you experience them, you will witness their progression toward ever-grander insights, pointing towards an as-yet-unfinished ultimate synthesis that will transform our understanding of the universe. […]
With almost 400,000 known species and thousands more identified every year, the variety of plant life is almost overwhelming—from the microscopic to the largest organism on Earth. In Plant Science: An Introduction to Botany, you will explore the astonishing adaptations that allow plants to live in an enormous variety of ecosystems, from deserts and the ocean floor to thousands of feet above sea level and on every continent.
