Of Mice and Memory
Here’s another injection of the Newsflux. For you brain hungry individuals, the best links and tips from the internet. We have an interesting study on mice and their memory, how men get touchy in the workplace, and more tips to up your brain game.
The best articles, research, technology and discoveries in brain news.
There’s been some recent discovery when it comes to putting new blood in old mice. It actually makes them young again.
It sounds like something out of a vampire novel or science fiction movie, but that’s exactly what scientists are doing.
When you dig into the details, however, it’s not quite the stuff of Hollywood movies. As we age there is an immune protein that builds up in our blood. The bad thing about it is that the protein blocks the birth of new brain cells and can lead to memory loss as we age. At least this is what they’ve found in mice.
When they inject the blood of old mice into younger mice, the researchers found that they become sluggish and forgetful. When younger blood is injected into older mice, the mice become more energetic and their memory improves.
When scientists altered the genes of mice to remove the immune protein, they found similar results. Those mice, too, had better memories and were able to learn tasks faster.
This gives scientists hope that they could have new angles of treatment to help us age gracefully.
Men Get Touchy About Gender
It seems that we might have a little problem when our boss is a female, fellas. New research from sociology says that guys can feel threatened in the workplace when their superior is of the opposite sex.
In several experiments men were found to be more assertive towards female managers that were seen to be self promoting or power seeking.
Men were found to be more aggressive when negotiating for a salary increase when participating against a woman than with a man. When females negotiated against a man or a woman manager, there was relatively no difference in the final salary amount.
The researchers note that it might be difficult for men to change this behavior, due to societal norms of masculinity. Which could make it a tough issue for female supervisors to deal with.
Aftershocks of Stroke
A few weeks back there was an article about how stroke was compared to aging your brain by about 8 years. Not exactly great news if you’re looking to stay independent into your twilight years.
It seems that the bad news has gotten worse for people that have had a stroke. Or at the risk of having one. A new study from the University of Michigan Health System reveals that memory and cognitive decline happen at an accelerated rate after a stroke incident. While we know that brain function is not the same after having the stroke, this is another serious side effect.
Cognition, learning, and verbal memory were some of the areas affected by faster decline in victims.
The authors of the study hope to find the reasons behind the increased decline. Possible causes may be poor rehabilitation, further brain injuries, changes in behavior, or other factors.
Tips, tricks, and hacks for getting the most out of your brain.
Jobs That Pay Your Brain
Your job is a big part of your life. You put significant amounts of time and energy into it every day. But have you ever wondered how that investment of time might be affecting your brain health?
Science is saying that it absolutely has an effect. Jobs that have challenging and thought provoking tasks can help maintain your memory and cognition into old age more than jobs that don’t engage your brain.
The study looked at over 1,000 people all aged at least 75 years of age. Participants were tested at regular intervals over 8 years and then matched against the data of their professional activities.
They found that people with mentally challenging jobs had better cognitive skills and also had slower rates of cognitive decline.
A lead author of the research said:
“Our study is important because it suggests that the type of work you do throughout your career may have even more significance on your brain health than your education does.”
So a good way to extend your brain’s abilities is to find a job that challenges you to think. It’s not only rewarding, but helps you age gracefully.
How to Get the Girl
Nobody likes a cocky person. So why do so many girls go out with cocky guys?
This isn’t a new question among good natured fellows. Many people can’t understand why a cocky person might seem attractive to women.
It’s not actually because they’re seen as more attractive. A recent experiment gives us a clue as to what’s going on. Researchers from the University of Queensland say that it might come down to how they act in a competitive environment.
The study found that while women aren’t initially more attracted to men who are over confident, the men aren’t as afraid to compete with others for a romantic partner.
Guys who may overestimate their abilities are more likely to stick to their guns and drive away competition. Interestingly enough, this tactic also works equally as well for women trying to compete for a man’s attention.
Tips to Develop an Exercise Habit
Exercise is great for a healthy functioning mind. But developing exercise habits are tough. So when I find something that can help, I feel obligated to share it with you because I know it’s a struggle.
The article talks about forming the cues – or instigation habits – that help get you off the couch. What works for some, may not work for others. They also say that it doesn’t have to be the same types of exercise all the time. Mixing up your routine is fine, if not beneficial.
For anyone thinking about getting into the habit of exercise, it may shed some light on how to start.
