Some people can memorize thousands of numbers, the names of dozens of strangers or the precise order of cards in a shuffled deck. Science writer and U.S. Memory Champion Joshua Foer shows how anyone can become a memory virtuoso, including him.
Forensic psychologist Scott Fraser studies how we remember crimes. He describes a deadly shooting and explains how eyewitnesses can create memories that they haven't seen. Why? Because the brain is always trying to fill in the blanks.
Nobel laureate and founder of behavioral economics Daniel Kahneman goes through a series of examples of things we might remember, from vacations to colonoscopies. He explains how our "experiencing selves" and our "remembering selves" perceive happiness differently.
Everybody itches. Sometimes itch serves as a useful warning signal — there's a bug on your back! But sometimes itch arises for no apparent reason, and can be a torment.
Think of the itchy skin disorder eczema, or the constant itching caused by some cancers. "A very high percentage of people who're on dialysis for chronic kidney disease develop severe itch that's very difficult to manage," says Dr. Ethan Lerner, an associate professor of dermatology at Harvard Medical School.
Scientists now say they've got a much better clue as to how itch happens.
Unusually warm ocean temperatures and favorable wind patterns mean the Atlantic is likely to see "an active or extremely active" hurricane season this year, say officials from the National Oceanic and Atmospheric Administration.
The agency expects between seven and 11 hurricanes and as many as 20 named storms during the 2013 season, which runs from June 1 through November.
At nearly seven miles below the water's surface, the Mariana Trench is the deepest spot in Earth's oceans. And the site north of Guam is where director and explorer James Cameron recently fulfilled a longtime goal of reaching the bottom in a manned craft.
For the dive, Cameron designed a 24-foot submersible vehicle, the Deepsea Challenger — "this kind of long, green torpedo that moves vertically through the water," as he tells All Things Considered's Melissa Block. Cameron was able to watch his descent, he says, through a window that was about 9-1/2 inches thick.
Quite a few medical school students have something against obese people, and most of those who have such a bias are unaware of it.
That's the conclusion of study appearing in the July issue of Academic Medicine. It was conducted at the Wake Forest School of Medicine in Winston-Salem, N.C. The study's author says the subconscious judgments could affect how patients are treated.
With memories of last year's Superstorm Sandy still fresh, NOAA is warning East Coasters and those farther inland to brace for another active Atlantic season, predicting that as many as six major storms will develop between the beginning of June and the end of November.
