Question: What are five things that people can do to be happier?
Shawn Achor: We discovered about five things so far that we know create a positive "Tetris Effect," this pattern in which the brain diverts resources to actually scan the world to not only make us happier, but actually to raise our levels of performance as well. One of those is writing down three things you’re grateful for every morning. Another one of those is journaling for five minutes a day about one positive experience you’ve had over the past 24 hours. Writing down ever detail you can. When individuals do that, the amazing thing is, our brains have a very difficult time in telling the difference what we are visualizing and what we’re actually experiencing.
In fact, if I put my hand in front of my face and look at it, area 17 in my visual cortex lights up. Now if I close my eyes and think about my hand in front of my face, that same part of my brain actually lights up, area 17 in my visual cortex. Which means, my brain actually can’t tell the difference between visualization and experience. So when I journal for just five minutes a day, I’m actually doubling the amount of positive experience that I have. And then over a period of 21 days when you do this, is what we did for the experiment, when you do this for a period of 21 days, your brain connects the dots between these meaningful moments creating a trajectory of meaning that pulls you through each day instead of having your pattern be, “I got through these lists of tasks and now I’m done.”
We’ve also found that meditation, for example, creates a positive Tetris Effect in the brain because it trains your brain to do a single thing at one time. For example, I’m working with Adobe right now trying to take their hands off their keyboards once a day for two minutes at a time. And when they do that, to just watch their breath go in and out; it doesn’t matter what they’re doing, all we’re trying to get them to do is to do one activity at a time.
What this helped us to undo is the negative effects of multi-tasking during the day. It creates a Tetris Effect of us taking those resources we have in our brain and shining it down like a laser on our tasks. Raising our levels of engagement of happiness and decreasing our levels of stress.
We also know that if an individual does a random act of kindness over the course of the day, for example, the original study done by [...] had executives do five kind acts. I can’t get most executives to do that but what I have them do is, when they first open their inbox during the day, I had them write a one- to two-sentence email praising or recognizing somebody on their team, a co-worker, a family member or friend. When individuals do that, we see something remarkable happen. Not only does it change the individual’s brain that’s writing the email, so now that they’re scanning the world for ways they can praise and recognize more, which we found in the research, can raise productivity levels on the team by up to 31%, which is amazing. But in addition to that, you’re also activating an entire team and raising the level of social support around you.
The single kind act we’ve seen not only rippled to the rest of the team, but because you’ve raised the level of social support... a study done at Yale actually found that social support, the social cohesion of the team was significantly more predictive of success rates than the number of years of experience or even the collective intelligence of the team.
So we found these several different tactics that we can do. And the last one is exercise. Everyone knows that exercise is supposed to make you happier, even if you hate exercise. But what we’ve found is that exercise, when you do it, creates a pattern in your brain, and a belief that your behavior matters. I find that when I exercise, I suddenly start eating healthier. Well I don’t have to eat healthier if I’m exercising, but my brain sees that my actions worked in one domain and it cascades out across the board. So we find that when people exercise in the morning, for example, it actually affects their productivity and their energy at work, raises their level of IQ at work and in addition to creating this cascade of success, where their brain keeps believing that their behavior matters. And what we’ve found is that the belief that your behavior matters, or what I find is optimism is one of the key predictors of success.

The Harvard positive psychology guru offers a few concrete ways for you to become happier today.
It's just the current cycle that involves opiates, but methamphetamine, cocaine, and others have caused the trajectory of overdoses to head the same direction
- It appears that overdoses are increasing exponentially, no matter the drug itself
- If the study bears out, it means that even reducing opiates will not slow the trajectory.
- The causes of these trends remain obscure, but near the end of the write-up about the study, a hint might be apparent
Through computationally intensive computer simulations, researchers have discovered that "nuclear pasta," found in the crusts of neutron stars, is the strongest material in the universe.
- The strongest material in the universe may be the whimsically named "nuclear pasta."
- You can find this substance in the crust of neutron stars.
- This amazing material is super-dense, and is 10 billion times harder to break than steel.
Superman is known as the "Man of Steel" for his strength and indestructibility. But the discovery of a new material that's 10 billion times harder to break than steel begs the question—is it time for a new superhero known as "Nuclear Pasta"? That's the name of the substance that a team of researchers thinks is the strongest known material in the universe.
Unlike humans, when stars reach a certain age, they do not just wither and die, but they explode, collapsing into a mass of neurons. The resulting space entity, known as a neutron star, is incredibly dense. So much so that previous research showed that the surface of a such a star would feature amazingly strong material. The new research, which involved the largest-ever computer simulations of a neutron star's crust, proposes that "nuclear pasta," the material just under the surface, is actually stronger.
The competition between forces from protons and neutrons inside a neutron star create super-dense shapes that look like long cylinders or flat planes, referred to as "spaghetti" and "lasagna," respectively. That's also where we get the overall name of nuclear pasta.

The researchers' computer simulations needed 2 million hours of processor time before completion, which would be, according to a press release from McGill University, "the equivalent of 250 years on a laptop with a single good GPU." Fortunately, the researchers had access to a supercomputer, although it still took a couple of years. The scientists' simulations consisted of stretching and deforming the nuclear pasta to see how it behaved and what it would take to break it.
While they were able to discover just how strong nuclear pasta seems to be, no one is holding their breath that we'll be sending out missions to mine this substance any time soon. Instead, the discovery has other significant applications.
One of the study's co-authors, Matthew Caplan, a postdoctoral research fellow at McGill University, said the neutron stars would be "a hundred trillion times denser than anything on earth." Understanding what's inside them would be valuable for astronomers because now only the outer layer of such starts can be observed.
"A lot of interesting physics is going on here under extreme conditions and so understanding the physical properties of a neutron star is a way for scientists to test their theories and models," Caplan added. "With this result, many problems need to be revisited. How large a mountain can you build on a neutron star before the crust breaks and it collapses? What will it look like? And most importantly, how can astronomers observe it?"
Another possibility worth studying is that, due to its instability, nuclear pasta might generate gravitational waves. It may be possible to observe them at some point here on Earth by utilizing very sensitive equipment.
The team of scientists also included A. S. Schneider from California Institute of Technology and C. J. Horowitz from Indiana University.

Scientists think constructing a miles-long wall along an ice shelf in Antarctica could help protect the world's largest glacier from melting.
- Rising ocean levels are a serious threat to coastal regions around the globe.
- Scientists have proposed large-scale geoengineering projects that would prevent ice shelves from melting.
- The most successful solution proposed would be a miles-long, incredibly tall underwater wall at the edge of the ice shelves.
The world's oceans will rise significantly over the next century if the massive ice shelves connected to Antarctica begin to fail as a result of global warming.
To prevent or hold off such a catastrophe, a team of scientists recently proposed a radical plan: build underwater walls that would either support the ice or protect it from warm waters.
In a paper published in The Cryosphere, Michael Wolovick and John Moore from Princeton and the Beijing Normal University, respectively, outlined several "targeted geoengineering" solutions that could help prevent the melting of western Antarctica's Florida-sized Thwaites Glacier, whose melting waters are projected to be the largest source of sea-level rise in the foreseeable future.
An "unthinkable" engineering project
"If [glacial geoengineering] works there then we would expect it to work on less challenging glaciers as well," the authors wrote in the study.
One approach involves using sand or gravel to build artificial mounds on the seafloor that would help support the glacier and hopefully allow it to regrow. In another strategy, an underwater wall would be built to prevent warm waters from eating away at the glacier's base.
The most effective design, according to the team's computer simulations, would be a miles-long and very tall wall, or "artificial sill," that serves as a "continuous barrier" across the length of the glacier, providing it both physical support and protection from warm waters. Although the study authors suggested this option is currently beyond any engineering feat humans have attempted, it was shown to be the most effective solution in preventing the glacier from collapsing.

An example of the proposed geoengineering project. By blocking off the warm water that would otherwise eat away at the glacier's base, further sea level rise might be preventable.
But other, more feasible options could also be effective. For example, building a smaller wall that blocks about 50% of warm water from reaching the glacier would have about a 70% chance of preventing a runaway collapse, while constructing a series of isolated, 1,000-foot-tall columns on the seafloor as supports had about a 30% chance of success.
Still, the authors note that the frigid waters of the Antarctica present unprecedently challenging conditions for such an ambitious geoengineering project. They were also sure to caution that their encouraging results shouldn't be seen as reasons to neglect other measures that would cut global emissions or otherwise combat climate change.
"There are dishonest elements of society that will try to use our research to argue against the necessity of emissions' reductions. Our research does not in any way support that interpretation," they wrote.
"The more carbon we emit, the less likely it becomes that the ice sheets will survive in the long term at anything close to their present volume."
A 2015 report from the National Academies of Sciences, Engineering, and Medicine illustrates the potentially devastating effects of ice-shelf melting in western Antarctica.
"As the oceans and atmosphere warm, melting of ice shelves in key areas around the edges of the Antarctic ice sheet could trigger a runaway collapse process known as Marine Ice Sheet Instability. If this were to occur, the collapse of the West Antarctic Ice Sheet (WAIS) could potentially contribute 2 to 4 meters (6.5 to 13 feet) of global sea level rise within just a few centuries."
