Your brain "wiggles" a little with every heartbeat
Looking for a heartbeat? Advances in the MRI field can now show you.
The human heartbeat. Pretty much everyone has one, and many kickass songs have been written about its existence. It may come to you as a surprise, then, that your heart and brain are currently doing something you didn't know it was doing before: dancing together with every heartbeat.
Well, it's more of a wiggle. And it's hardly Mambo Number 5... it's a very slight wiggle. Barely detectable, but happens when cerebrospinal fluid gets pumped up the spine. Take a look for yourself, thanks to researchers at the University of Auckland and Stanford University:

It's detected by a special MRI called amplified MRI, that can show the movement better than regular MRIs can. Researchers could use this data on the brain wiggling to help create better helmets, and even go as far to potentially spot future aneurysms.
Cardiac gating during MRIs is nothing new, but amplified MRIs take what is cardiac gating tries to avoid (i.e., and I'm paraphrasing HUGELY here, but cardiac gating is done to prevent a blurred MRI) and record the full thing in detail. Still want another analogy? Regular MRIs are 480p resolution, and amplified MRIs are 4K.
Pfizer's partnerships strengthen their ability to deliver vaccines in developing countries.
- Pfizer is helping to drive the UN's sustainable development goals through partnerships.
Swiss researchers identify new dangers of modern cocaine.
- Cocaine cut with anti-worming adulterant levamisole may cause brain damage.
- Levamisole can thin out the prefrontal cortex and affect cognitive skills.
- Government health programs should encourage testing of cocaine for purity.
Sarco assisted suicide pods come in three different styles, and allow you to die quickly and painlessly. They're even quite beautiful to look at.
Death: it happens to everyone (except, apparently, Keanu Reeves). But while the impoverished and lower-class people of the world die in the same ol' ways—cancer, heart disease, and so forth—the upper classes can choose hip and cool new ways to die. Now, there's an assisted-suicide pod so chic and so stylin' that peeps (young people still say peeps, right?) are calling it the "Tesla" of death... it's called... the Sarco!
Civil discourse has fallen to an all time low.
The question that the American populace needs to ask itself now is: how do we fix it?
Discursive fundamentals need to be taught to preserve free expression
In their findings the authors state:
upholding First Amendment ideals.
Talking politics at Thanksgiving dinner
- Progressive Activists: younger, highly engaged, secular, cosmopolitan, angry.
- Traditional Liberals: older, retired, open to compromise, rational, cautious.
- Passive Liberals: unhappy, insecure, distrustful, disillusioned.
- Politically Disengaged: young, low income, distrustful, detached, patriotic, conspiratorial
- Moderates: engaged, civic-minded, middle-of-the-road, pessimistic, Protestant.
- Traditional Conservatives: religious, middle class, patriotic, moralistic.
- Devoted Conservatives: white, retired, highly engaged, uncompromising,
It's interesting to note the authors found that:
"Tribe membership shows strong reliability in predicting views across different political topics."
Here are some statistics on differing viewpoints according to political party:
- 51% of staunch liberals say it's "morally acceptable" to punch Nazis.
- 53% of Republicans favor stripping U.S. citizenship from people who burn the American flag.
- 65% of Republicans say NFL players should be fired if they refuse to stand for the anthem.
- 58% of Democrats say employers should punish employees for offensive Facebook posts.
- 47% of Republicans favor bans on building new mosques.
Here are some guidelines for civic discourse that might come in handy:
- Practice inclusion and listen to who you're speaking to.
Civic discourse in the divisive age
dangerously tribal, fueled by a culture of outrage and taking offense. For the combatants,
the other side can no longer be tolerated, and no price is too high to defeat them.
These tensions are poisoning personal relationships, consuming our politics and
putting our democracy in peril.
Once a country has become tribalized, debates about contested issues from
immigration and trade to economic management, climate change and national security,
become shaped by larger tribal identities. Policy debate gives way to tribal conflicts.
Polarization and tribalism are self-reinforcing and will likely continue to accelerate.
The work of rebuilding our fragmented society needs to start now. It extends from
re-connecting people across the lines of division in local communities all the way to
building a renewed sense of national identity: a bigger story of us."
