Tell a caffeine addict she can’t drink a cup of coffee first thing in the morning and things could get a little ugly—or maybe not.
Coffee is more than just a fetishized drink or a daily ritual. It has the power to transform your productivity. But maybe we’ve been going about it all wrong.
Researcher Steven Miller of the Uniformed Services University of Health Sciences in Bethesada found that because our bodies already produce natural hormones that make us feel more alert at certain times in the day, we should curb our caffeine consumption during these times so as not to diminish its effect when we need it most.
He found that the best times to drink coffee (or any caffeinated beverage) for those who wake up between 6 a.m. and 8 a.m. is from 9:30 a.m. and 11:30 a.m. and between 1:30 p.m. to 5:30 p.m., since this is when our cortisol levels usually drop off and we begin to feel sluggish.
In other words, having a cup of coffee when you first get up doesn’t actually make you feel more awake.
While the science behind this seemed pretty sound, we wanted to know if the payoff for adjusting our coffee consumption is worth the sacrifice. Some were able to pull it off and loved the results, while others weren’t even able to make a dent in the challenge.

Giant academic social networks have taken off to a degree that no one expected even a few years ago. A Nature survey explores why.
Scientists have developed a new device that mimics the way octopuses blend in with their surroundings to hide from dangerous predators.
Do people read as well on screens as they do on paper? Scientists aren’t quite sure. While the type of E Ink used in the latest generation of Kindles and other tablets has been shown to be as or even more legible than printed text, other studies have indicated that — in terms of reading comprehension — the medium doesn’t much matter.
But a forthcoming paper by researchers in France and Norway suggests that there may be some cognitive drawbacks to reading even short works of literature on a screen.
Could a video game a day keep the doctor away? New research from Oxford University shows that kids who engage in less than an hour of video game playing each day are better adjusted and have fewer conduct problems than those who have never played or those who play for three hours or more.
Emerging research suggests a student’s mental framework influences their recall of material.
“When compared to learners expecting a test, learners expecting to teach recalled more material correctly, they organized their recall more effectively and they had better memory for especially important information,” said lead author John Nestojko, Ph.D.
An emerging theory suggests exposure to narrative fiction can improve an individual’s ability to understand what other people are thinking or feeling.
The bioengineering students who won last April’s George R. Brown School of Engineering Design Showcase and Competition for their R-ARM, a robotic device for Faught that fits his motorized chair, had the eager team try a nearly finished version Sept. 20 at Shriner’s Hospital for Children in Houston.
The arm will allow Faught, who lives with osteogenesis imperfecta, a genetic condition that makes his bones especially brittle, to perform tasks most people take for granted.
A seven-year-old Chinese boy whose eyes were gouged out in an attack last year is able to see objects through a Brainport device by sending vibrations through the boy’s tongue nerves.

People with bachelor’s degrees in science, technology, engineering and math are more likely than other college graduates to have a job, but most of them don’t work in STEM occupations, according to a U.S. Census Bureau report released Thursday.
Nearly 75 percent of all holders of bachelor’s degrees in STEM disciplines don’t have jobs in STEM occupations, according to a survey that reached 3.5 million homes, said Liana Christin Landivar, a sociologist with the Census Bureau. The bureau’s American Community Survey is the largest household survey in the nation.
About half of those who have degrees related to engineering, computers, math and statistics do get a STEM job, the survey found.
A new study suggests posting sexy or revealing photos by girls and young women on social media sites gives their female peers a bad impression.
“There is so much pressure on teen girls and young women to portray themselves as sexy, but sharing those sexy photos online may have more negative consequences than positive,” Daniels said.
A new experimental study analyzed how cooperative attitudes evolve in different age ranges. Researchers found that young people between the ages of ten and sixteen demonstrate more fickle behavior when it comes to cooperating, unlike other age groups. People over the age of 66 demonstrated the most cooperative behavior.
