JARREN VINK CHILI Red jalapeños give rooster sauce its heat; they clock in at about 5,000 Scoville units, or around 300 parts per million of mouth-burning capsaicinoids. These molecules bind to a receptor, TRPV1, that shows up on the ends of nerves that lead to the trigeminal nerve, which conveys touch, temperature, and pain. GARLIC […]
I like to clip my nails, because I’m addicted to the rewarding little tink of the clippers. Instead of being content with a finely manicured set of man hands, I crave more tinks. Without fail, I’ll kick off my sneakers in hopes of clipping away my toe talons, but instead of tinks, all I make is a loud sigh, because my toenails […]
At a recent event hosted by the Motion Picture Academy of Arts and Sciences, neuroscientists and cognitive psychologists got together with film makers to discuss what both groups have learned---the scientists through painstaking experiments and analysis, and the film makers by intuition and experience---about the mechanisms of attention and perception.
We’re coming up on one whole year of Absurd Creature of the Week! So to celebrate, we’ve used a super-secret, super-complex algorithm to choose the most absurd of the absurd—to pit them against each other in mortal combat. For the next week and a half, we’ll present you with matchups. The first round is split […]
Mass and length may not be fundamental properties of nature, according to new ideas bubbling out of the multiverse.
Zombie ants, the ghostly slaves of a mind-controlling fungus seen creeping around places like South America for years, have now been spotted in the United States. But don’t panic—they’ve probably been here all along, and we only just now noticed. Scientists at Penn State have for the first time shown that a fungus here in the U.S. invades […]
My father worked for over 30 years in construction, falling off of ladders and getting slivers of metal in his eye and generally bleeding profusely. He toiled like a maniac so our family could eat, all while furthering one of humanity’s most indispensable inventions: large-scale construction of shelter. From the most modest roof that my […]
Consider the following question that has been asked at actual Google job interviews: How much does the Empire State Building weigh? Now, there is no correct answer to this question in any practical sense because no one knows the answer. Google isn’t interested in the answer, though; they’re interested in the process.
The risk posed to aircraft by airborne volcanic ash is as bad as ever, but airlines are better equipped to spot and avoid trouble---and save money---than they were four years ago.
ATLANTA—Kent Brantly and Nancy Writebol have recovered. The two American aid workers, who since early August had been receiving treatment for Ebola at Emory University Hospital, are being released—hospital officials in Atlanta cited multiple clean blood tests for both. Standing in front of a press conference this morning, Brantly simply said “I am thrilled to be […]
Researchers created visual and DNA analysis of how anoles regenerate their tails.
A new study published today in PLOS One shows that golden orb weaver spiders living near heavily urbanized areas in Sydney, Australia tend to be bigger, better fed, and have more babies than those living in places less touched by human hands.
If you’re a millennial like me, you remember the Nickelodeon show Are You Afraid of the Dark?, in which kids sit around a campfire (or flickering stage lights or whatever), taking turns giving each other anxiety disorders with scary stories. The title is a bit of a silly question, though. Everyone is to some degree […]
How does the meteorologist know what the temperature feels like to me and you?
Adam Voorhes In January of this year, the first subject checked into the metabolic ward at the National Institutes of Health in Bethesda, Maryland, to participate in one of the most rigorous dietary studies ever devised. For eight weeks, he was forbidden to leave. He spent two days of each week inside tiny airtight rooms […]
Pretend for a minute that it’s 1875 and you’re a mining engineer whose job it is to figure out how much gold is in them thar hills. Get it wrong, and your company is going to waste a lot of time and money hunting for gold that’s not there—or worse yet, miss out on the mother […]
Every time Daniel Bausch, a virologist from Tulane University, went back to Guinea, things looked worse. The country’s few paved roads crumbled. The forests seemed thinner. Prices shot up on everything in the market. From 1998 to 2008, Bausch was working for the World Health Organization in West Africa, chasing a viral disease called Lassa. […]
Bryan Christie Design Deep-sea explorers and scientists have long relied on the Alvin submersible, based in Woods Hole, Massachusetts, to visit the abyssal depths. But after 50 years of diving everywhere from hydrothermal vents to the wreckage of the Titanic, it was ready for a makeover. Three years and $41 million later, Alvin is back […]
To teach children not to lie, extolling the virtues of honesty may be more effective than focusing on the punishing consequences of deception.
SAN FRANCISCO—Clouds can carry millions of pounds of water, but that doesn’t mean rain and snow just happen. Hundreds of thousands of water vapor molecules need to freeze together as ice before they are heavy enough to fall to the ground. But, the water molecules need a bit of dust or other microscopic matter to latch onto in order […]
