Mama, Don't Let Your Babies Grow Up To Deny Evolution

If adults want to deny evolution, sure. That’s fine. Whatever. But those adults better not make their kids follow in step because we as society need them to be better. Bill Nye, everyone's favorite Science Guy, explains the importance of promoting evolution education for America's future voters and lawmakers.

My Man, Sir Isaac Newton

Are you at least 26 years-old? If so, you are older than Isaac Newton was when he invented calculus... on a dare! (If you're younger than 26, better hurry up.) Big Think expert and overall cool guy Neil deGrasse Tyson explains why Newton is the greatest physicist who ever and likely will ever live.

Will Mankind Destroy Itself?

Theoretical physicist Michio Kaku sees two major trends today. One eventually leads to a multicultural, scientific, tolerant society that will expand beyond Earth in the name of human progress. The other trend leads to fundamentalism, monoculturalism, and -- eventually -- civilizational ruin. Whichever of these two trends wins out will determine the fate of mankind. No pressure, everyone.

Ricky Gervais on the Principles of Comedy

Comedy isn't just about making people laugh, says actor Ricky Gervais. It's about making people think. And while different forms of comedy require different approaches, the crux of any good performance will always be rhythm.

Reading the Bible (Or the Koran, Or the Torah) Will Make You an Atheist

Author and magician Penn Jillette was asked to leave his Christian youth group by a pastor who told his parents: "He's no longer learning about the Bible from me. He is now converting everyone in the class to atheism." The reason? Jillette did his homework and was turned off by the hostilities of the text. It can be intimidating to come out as an atheist, especially in a religious community. Jillette found that having "out" atheist role models helped him feel unalone.

Henry Rollins: The One Decision that Changed My Life Forever

Punk legend Henry Rollins describes the biggest turning point in his life: the moment he decided to leave his job as manager of a Häagen-Dazs store and eventually become the lead singer of Black Flag. It was the courage to take a risk, plus a whole lot of luck, that got Rollins to where he is today.

James Gleick on the Common Character Traits of Geniuses

This video is part of a series on female genius, in proud collaboration with 92Y's 7 Days of Genius Festival.


The personalities of Isaac Newton and Richard Feynman were, on one level, extremely different. Biographer and former New York Times reporter James Gleick says Newton was argumentative, had few friends, and likely died a virgin. Feynman, on the other hand, loved dancing and going to parties, and had many friends in the scientific community. But in regards to their working habits, both men were solitary and had the ability to concentrate with a sort of intensity that is hard for mortals to grasp. At bottom, Gleick says geniuses tend to have a yearning for solitude which, though fruitful for their professional work, made the task of daily living more burdensome.

The Importance of Doing Useless Things

From poetry and ballet to mathematics and being clever, life is laden with frivolous pursuits that hold no bearing on our ability to survive. Yet, insists Richard Dawkins, if it weren’t for the development of these impractical activities, we wouldn’t be here.

Here's How to Catch a Liar, If You Really Want To

It’s very complex as to whether or not we really want to catch a liar. We think we do. What if we find out that both of our presidential candidates are lying? Then what do we do? I’m not saying they are; I never comment on anyone in office or running for office. Only after they’re out that they’re fair game. . . .

An international team of astronomers has conducted the biggest survey of stellar nurseries to date, charting more than 100,000 star-birthing regions across our corner of the universe.

Stellar nurseries: Outer space is filled with clouds of dust and gas called nebulae. In some of these nebulae, gravity will pull the dust and gas into clumps that eventually get so big, they collapse on themselves — and a star is born.

These star-birthing nebulae are known as stellar nurseries.

The challenge: Stars are a key part of the universe — they lead to the formation of planets and produce the elements needed to create life as we know it. A better understanding of stars, then, means a better understanding of the universe — but there's still a lot we don't know about star formation.

This is partly because it's hard to see what's going on in stellar nurseries — the clouds of dust obscure optical telescopes' view — and also because there are just so many of them that it's hard to know what the average nursery is like.

The survey: The astronomers conducted their survey of stellar nurseries using the massive ALMA telescope array in Chile. Because ALMA is a radio telescope, it captures the radio waves emanating from celestial objects, rather than the light.

"The new thing ... is that we can use ALMA to take pictures of many galaxies, and these pictures are as sharp and detailed as those taken by optical telescopes," Jiayi Sun, an Ohio State University (OSU) researcher, said in a press release.

"This just hasn't been possible before."

Over the course of the five-year survey, the group was able to chart more than 100,000 stellar nurseries across more than 90 nearby galaxies, expanding the amount of available data on the celestial objects tenfold, according to OSU researcher Adam Leroy.

New insights: The survey is already yielding new insights into stellar nurseries, including the fact that they appear to be more diverse than previously thought.

"For a long time, conventional wisdom among astronomers was that all stellar nurseries looked more or less the same," Sun said. "But with this survey we can see that this is really not the case."

"While there are some similarities, the nature and appearance of these nurseries change within and among galaxies," he continued, "just like cities or trees may vary in important ways as you go from place to place across the world."

Astronomers have also learned from the survey that stellar nurseries aren't particularly efficient at producing stars and tend to live for only 10 to 30 million years, which isn't very long on a universal scale.

Looking ahead: Data from the survey is now publicly available, so expect to see other researchers using it to make their own observations about stellar nurseries in the future.

"We have an incredible dataset here that will continue to be useful," Leroy said. "This is really a new view of galaxies and we expect to be learning from it for years to come."

  • NASA estimates that more than 500,000 pieces of space trash larger than a marble are currently in orbit. Estimates exceed 128 million pieces when factoring in smaller pieces from collisions. At 17,500 MPH, even a paint chip can cause serious damage.
  • To prevent this untrackable space debris from taking out satellites and putting astronauts in danger, scientists have been working on ways to retrieve large objects before they collide and create more problems.
  • The team at Clearspace, in collaboration with the European Space Agency, is on a mission to capture one such object using an autonomous spacecraft with claw-like arms. It's an expensive and very tricky mission, but one that could have a major impact on the future of space exploration.

  • Bristle worms are odd-looking, spiky, segmented worms with super-strong jaws.
  • Researchers have discovered that the jaws contain metal.
  • It appears that biological processes could one day be used to manufacture metals.

The bristle worm, also known as polychaetes, has been around for an estimated 500 million years. Scientists believe that the super-resilient species has survived five mass extinctions, and there are some 10,000 species of them.

Be glad if you haven't encountered a bristle worm. Getting stung by one is an extremely itchy affair, as people who own saltwater aquariums can tell you after they've accidentally touched a bristle worm that hitchhiked into a tank aboard a live rock.

Bristle worms are typically one to six inches long when found in a tank, but capable of growing up to 24 inches long. All polychaetes have a segmented body, with each segment possessing a pair of legs, or parapodia, with tiny bristles. ("Polychaeate" is Greek for "much hair.") The parapodia and its bristles can shoot outward to snag prey, which is then transferred to a bristle worm's eversible mouth.

The jaws of one bristle worm — Platynereis dumerilii — are super-tough, virtually unbreakable. It turns out, according to a new study from researchers at the Technical University of Vienna, this strength is due to metal atoms.

Metals, not minerals

This is pretty unusual. The study's senior author Christian Hellmich explains: "The materials that vertebrates are made of are well researched. Bones, for example, are very hierarchically structured: There are organic and mineral parts, tiny structures are combined to form larger structures, which in turn form even larger structures."

The bristle worm jaw, by contrast, replaces the minerals from which other creatures' bones are built with atoms of magnesium and zinc arranged in a super-strong structure. It's this structure that is key. "On its own," he says, "the fact that there are metal atoms in the bristle worm jaw does not explain its excellent material properties."

Just deformable enough

What makes conventional metal so strong is not just its atoms but the interactions between the atoms and the ways in which they slide against each other. The sliding allows for a small amount of elastoplastic deformation when pressure is applied, endowing metals with just enough malleability not to break, crack, or shatter.

Co-author Florian Raible of Max Perutz Labs surmises, "The construction principle that has made bristle worm jaws so successful apparently originated about 500 million years ago."

Raible explains, "The metal ions are incorporated directly into the protein chains and then ensure that different protein chains are held together." This leads to the creation of three-dimensional shapes the bristle worm can pack together into a structure that's just malleable enough to withstand a significant amount of force.

"It is precisely this combination," says the study's lead author Luis Zelaya-Lainez, "of high strength and deformability that is normally characteristic of metals.

So the bristle worm jaw is both metal-like and yet not. As Zelaya-Lainez puts it, "Here we are dealing with a completely different material, but interestingly, the metal atoms still provide strength and deformability there, just like in a piece of metal."

Observing the creation of a metal-like material from biological processes is a bit of a surprise and may suggest new approaches to materials development. "Biology could serve as inspiration here," says Hellmich, "for completely new kinds of materials. Perhaps it is even possible to produce high-performance materials in a biological way — much more efficiently and environmentally friendly than we manage today."

  • Anchoring is a common bias that makes people fixate on one piece of data.
  • A study showed that those who experienced rudeness were more likely to anchor themselves to bad data.
  • In some simulations with medical students, this effect led to higher mortality rates.

Cognitive biases are funny little things. Everyone has them, nobody likes to admit it, and they can range from minor to severe depending on the situation. Biases can be influenced by factors as subtle as our mood or various personality traits.

A new study soon to be published in the Journal of Applied Psychology suggests that experiencing rudeness can be added to the list. More disturbingly, the study's findings suggest that it is a strong enough effect to impact how medical professionals diagnose patients.

Life hack: don't be rude to your doctor

The team of researchers behind the project tested to see if participants could be influenced by the common anchoring bias, defined by the researchers as "the tendency to rely too heavily or fixate on one piece of information when making judgments and decisions." Most people have experienced it. One of its more common forms involves being given a particular value, say in negotiations on price, which then becomes the center of reasoning even when reason would suggest that number should be ignored.

It can also pop up in medicine. As co-author Dr. Trevor Foulk explains, "If you go into the doctor and say 'I think I'm having a heart attack,' that can become an anchor and the doctor may get fixated on that diagnosis, even if you're just having indigestion. If doctors don't move off anchors enough, they'll start treating the wrong thing."

Lots of things can make somebody more or less likely to anchor themselves to an idea. The authors of the study, who have several papers on the effects of rudeness, decided to see if that could also cause people to stumble into cognitive errors. Past research suggested that exposure to rudeness can limit people's perspective — perhaps anchoring them.

In the first version of the study, medical students were given a hypothetical patient to treat and access to information on their condition alongside an (incorrect) suggestion on what the condition was. This served as the anchor. In some versions of the tests, the students overheard two doctors arguing rudely before diagnosing the patient. Later variations switched the diagnosis test for business negotiations or workplace tasks while maintaining the exposure to rudeness.

Across all iterations of the test, those exposed to rudeness were more likely to anchor themselves to the initial, incorrect suggestion despite the availability of evidence against it. This was less significant for study participants who scored higher on a test of how wide of a perspective they tended to have. The disposition of these participants, who answered in the affirmative to questions like, "Before criticizing somebody, I try to imagine how I would feel if I were in his/her place," was able to effectively negate the narrowing effects of rudeness.

What this means for you and your healthcare

The effects of anchoring when a medical diagnosis is on the line can be substantial. Dr. Foulk explains that, in some simulations, exposure to rudeness can raise the mortality rate as doctors fixate on the wrong problems.

The authors of the study suggest that managers take a keener interest in ensuring civility in workplaces and giving employees the tools they need to avoid judgment errors after dealing with rudeness. These steps could help prevent anchoring.

  • Here's one pandemic project we approve of: a map of the United Fonts of America.
  • The question was simple: How many fonts are named after places in the U.S.?
  • Finding them became an obsession for Andy Murdock. At 222, he stopped looking.

Who isn't fond of fonts? Even if we don't know their names, we associate specific letter types with certain brands, feelings, and levels of trust.

Typography equals psychology. For example, you don't want to get a message from your doctor, or anybody else in authority, that's set in comic sans — basically, the typeface that wears clown makeup.

A new serif in town

If you want to convey reliability, tradition, and formality, you should go for a serif, a font with decorative bits stuck to its extremities. Well-known examples include Garamond, Baskerville, and Times New Roman. Remove the decoration, and you've got a clean look that communicates clarity, modernity, and innovation. Arial and Helvetica are some of the most popular sans serif fonts.

There's a lot more to font psychology, but let's veer toward another, less explored Venn diagram instead: the overlap between typography and geography. That's where Andy Murdock spent much of his pandemic.

Mr. Murdock is the co-founder of The Statesider, a newsletter about (among other things) travel and landscape in the United States. He remembers his first encounter with a home computer back in 1984 and learning from that Macintosh both the word "font" and the name for the one it used: Chicago.

You can see where this is going. Mr Murdock retained a healthy interest in fonts named after places. Over the years, he noted Monaco, London, San Francisco, and Cairo, among many others. "And then, the question of how many fonts are named for U.S. places came up in an editorial meeting at The Statesider," Mr Murdock says.

It's the sort of topic that in other times might never have gone anywhere, but this was the start of the pandemic. "I was stuck for days on end, so I actually started looking into it. At some point, I realized that I could probably find at least one per state." Cue the idea for a map of the "United Fonts of America."

Challenge turns into obsession

But that was easier said than done. Finding location-based fonts turned out to be rather time-consuming. "I definitely didn't realize what I was getting myself into," Mr Murdock recalls. "I could quickly name a few — New York, Georgia, Chicago — but I had no idea that I'd be able to find so many."

What started as a quirky challenge turned into an obsession and a compulsion that would have the accidental font-mapper wake up in the middle of the night and think: Did I check to see if there's a Boise font? (He did; there isn't.)

"The hardest part was knowing when to stop," said Mr Murdock. "Believe me, I know I missed some." In all, he found 222 fonts referencing places in the United States and its territories.

For the most part, these fonts are distributed as the population is: heavy on the coasts and near the Great Lakes, but thin in most parts in between. California (23 fonts) takes the cake, followed by Texas (15), and New York (9).

Some of the fonts have interesting back stories, and in his article for "The Statesider", Mr Murdock provides a few:

  • Georgia was named after a newspaper headline reading "Alien Heads Found in Georgia."
  • Fayette is based on the handwriting of the record-keeper of a place called Fayette, now a ghost town in Michigan's Upper Peninsula.
  • Tahoma and Tacoma are both pre-European names for Mount Rainier in Washington state.

Mostly, the fonts repeat the names of states and cities, but some offer something more interesting, such as the alliterating Cascadia Code or the lyrical Tallahassee Chassis. Other less than ordinary names include Kentuckyfried and Wyoming Spaghetti.

Capturing the spirit of a place

As an unexpected expert in the geographic distribution of location-based fonts, can Mr. Murdock offer any opinion on the qualitative relation between place and typeface?

"Good design of any sort can capture the spirit of a place, or at least one perspective on a place," he says, "but frankly, that only occasionally seems to have been the goal when it comes to typefaces."

In his opinion, the worst fonts reflect a stereotype about a place, rather than the place itself: "Saipan and Hanalei are both made to look like crude bamboo. Those are particularly awful. Pecos feels like it belongs on a bad Tex-Mex restaurant's menu."

"Santa Barbara Streets, on the other hand, is quite nice because it captures the font that's actually used on street signs in Santa Barbara. I prefer the typefaces that have a story and a connection to a place, but it's a fine line between being artfully historic and being cartoonishly retro."

Let's finish off Route 66

Glancing over the map, some regions seem more prone to "stereotypefacing" than others: "Tucson, Tombstone, El Paso — you know you're in the Southwest. Art Deco fonts are mostly in the east or around the Great Lakes. In general, you find more sans serif fonts in the western U.S., and more serif fonts in the east, but that's not a hard-and-fast rule."

Noticing a few blank spots on the map, Mr. Murdock helpfully suggests some areas that could do with a few more fonts, including the Carolinas, the Dakotas, Maine, Missouri, West Virginia, New Jersey, and Rhode Island.

Oh, and Route 66. Nearly all of the cities mentioned in the eponymous song have a typeface named after them. "We need Gallup and Barstow to complete the set."

And finally, America's oft-overlooked overseas territories could be a rich seam for type developers: "Some of these names are perfect for a great typeface — Viejo San Juan, St. Croix, Pago Pago, Ypao Beach, Tinian."

To name but a few. Typeface designers, sharpen your pencils!
