Your brain on carbohydrates and fat? It's in love
Pizza? Doughnuts? They satisfy the brain's reward center like nothing else.
Then, they were asked to estimate how many calories and how much they'd pay for it.
"Surprisingly, foods containing fats and carbohydrates appear to signal their potential caloric loads to the brain via distinct mechanisms. Our participants were very accurate at estimating calories from fat and very poor at estimating calories from carbohydrate," explained Dana Small, director of the Modern Diet and Physiology Research Center at Yale University.
The kicker? People would also pay more money for the foods containing both fat and carbs. Oh, and it's very hard to stop eating them once you start.
The key is in the reward center of the brain; these foods can light that right up, and release dopamine, the hormone that says, "Wow. I love this."
With further study, it's possible for scientists to figure out how to turn off that reward center, at least to a certain extent; as it is now, eating those foods tends to hit the reward center of the brain so much that it's very hard for us to stop eating when we start. It's not the same as other foods—in fact, it's not all that recent that these foods were created, so they calculate that the brain doesn't really know how to handle them. Before those foods were invented, humans didn't have these kinds of options nearly as much as we do today.
The study also discovered that the brain can handle either carbs or fat, but not both at the same time; when presented with such an option, it doesn't know quite how to respond.
So... bring on the donuts?
Antimicrobial resistance is growing worldwide, rendering many "work horse" medicines ineffective. Without intervention, drug-resistant pathogens could lead to millions of deaths by 2050. Thankfully, companies like Pfizer are taking action.
- Antimicrobial-resistant pathogens are one of the largest threats to global health today.
- As we get older, our immune systems age, increasing our risk of life threatening infections. Without reliable antibiotics, life expectancy could decline for the first time in modern history.
- If antibiotics become ineffective, common infections could result in hospitalization or even death. Life-saving interventions like cancer treatments and organ transplantation would become more difficult, more often resulting in death. Routine procedures would become hard to perform.
- Without intervention, resistant pathogens could result in 10 million annual deaths by 2050.
- By taking a multi-faceted approach—inclusive of adherence to good stewardship, surveillance and responsible manufacturing practices, as well as an emphasis on prevention and treatment—companies like Pfizer are fighting to help curb the spread.
No, the Syrian civil war is not over. But it might be soon. Time for a recap
- The War in Syria has dropped off the radar, but it's not over (yet)
- This 1-minute video shows how the fronts have moved – and stabilised – over the past 22 months
- Watching this video may leave you both better informed, and slightly queasy: does war need a generic rock soundtrack?
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!
Entrepreneur and author Andrew Horn shares his rules for becoming an assured conversationalist.
- To avoid basing action on external validation, you need to find your "authentic voice" and use it.
