When you need to see a doctor, surely you will want to see a good one. But there is one important thing you may never have thought about: Has your doctor rested enough?

Doctors in our country often have to work 34 hours or longer without sleep. Most of them work 104 hours a week, and some even 150. (There are only 168 hours a week!) One report said that a doctor who works such long hours cannot think more clearly than a drunk driver. Another found that doctors who sleep 5.8 fewer hours than the week before might make 22% more serious mistakes. Surely no one wants to get in a car that is driven by a drunk driver. So, how safe would you feel when you are under the care of a tired doctor?

Sadly this problem has been around for a long time. There are no laws about it yet and hospital bosses don’t look like they care either. And that is why we doctors are asking you to join us on the street this Sunday. Fight together with us on the street so we can fight better for your life in the hospital.

A workday filled with mentally challenging tasks can make people feel worn out and desire a relaxing evening of TV shows. A study led by Antonius Wiehler of Pitié-Salpêtrìère University Hospital provides an explanation for this familiar phenomenon.

Researchers arranged for two sets of subjects to work for over six hours. The first group was assigned a difficult version of tasks, while the second was given a simple version. They measured levels of glutamate (谷氨酸) that collected in the cognitive area of subjects’ brains, finding higher levels of the chemical appeared in the first group, although both groups reported feeling similar levels of tiredness after the daylong experiment. Glutamate helps learning and memory, but too much glutamate can give rise to brain cell damage.

Also, when researchers offered financial choices, as a measure of whether the difficulty of work affected subjects’ decision-making ability, those finishing harder tasks were more likely to choose to take home an immediate reward rather than wait for a larger cash-out at a later date. “Existing theories suggested fatigue (疲劳) is an unreal feeling cooked up by the brain to make us relax,” Wiehler says. “Yet our findings provide proof that cognitive work causes the collection of bad substances, so fatigue would be signal that makes us stop working but for a different purpose: to preserve normality of brain functioning.”

“Defining what fatigue is remains a challenge for the field, says neuroscientist Matthew Apps, “but it’s exciting that this experiment provides a reasonable alternative explanation that is of great help.” He notes some areas where these findings might come in. For people in jobs requiring intense focus, burnout can lead to damaging consequences. Preventing glutamate’ building may help maintain attention. Another area of interest would be researching clinical conditions related to fatigue. The presence of glutamate might reveal why patients struggle with fatigue.

For Wiehler, open questions remain. One limitation is their focus on the brain’s specific region, so what impact cognitively effortful work has on the rest parts remains to be seen. In addition, it’s not yet clear how the balance of glutamate is restored after rest. “Maybe it leaves the brain during sleep,” Wiehler says. “There’s tons of research to come.”

Have you ever wondered how your favorite NBA team received its famous name? All NBA teams have an interesting story or a history behind their names. Some of the names reflected the city’s culture or history, others came from previous owners and many were selected through “Name the Team” contests.

For teams like the Los Angeles Lakers and the Utah Jazz, the names were not always a reflection of the city. Even though Los Angeles has no lakes, the Lakers name has been a city treasure for almost 40 years. Before going to Los Angeles, the team originated in Minneapolis, Minnesota. In1947, team officials changed the name to the Lakers to reflect the Minnesota State’s nickname, “Land of 10,000 Lakes”. The team name went unchanged after moving to Los Angeles in1960.

Because the Utah’s team originated in New Orleans, Louisiana, it was called the Jazz. In 1974, New Orleans club officials chose the name to represent the city for its reputation as the “Jazz Capital of the World”. The name stayed with the team even after they found a new home in Salt Lake City, Utah in 1979.

The original owner of the Chicago Bulls, Richard Klein, named the team the Bulls. He picked the name because a fighting bull is relentless and never quits. Klein, who founded the club in 1966, believed these qualities were necessary for a championship team and hoped his Chicago athletes would live up to the team name. The Bulls, the winner of the six NBA championships, has definitely followed the belief.

In 1967, the Indiana Pacers selected their team name in a different way from most other teams. Their decision was based on what they wanted to achieve in the NBA. Team officials chose the Pacers name because the organization wanted to set the “pace” in professional basketball.
