Aggression causes new nerve cells to be generated in the brain

A group of neurobiologists from Russia and the USA, including Dmitry Smagin, Tatyana Michurina, and Grigori Enikolopov from Moscow Institute of Physics and Technology (MIPT), have proven experimentally that aggression has an influence on the production of new nerve cells in the brain. The scientists conducted a series of experiments on male mice and published their findings in the journal Frontiers in Neuroscience.

Researchers from the Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences (ICG SB RAS), MIPT, Cold Spring Harbour Laboratory, and Stony Brook University and School of Medicine studied the changes that occurred in the brains of mice demonstrating aggressive behaviour, which attacked other mice and won in fights. After a win, these mice became even more aggressive, and new neurons appeared in their hippocampus - one of the key structures of the brain; in addition to this, in mice that were allowed to continue fighting certain changes were observed in the activity of their nerve cells.

Where We Drill, We Spill: Commemorating Exxon Valdez

The Trump "starvation" budget would axe funding to the already beleaguered and under resourced agencies tasked with managing oil drilling safety risks, effectively taking what few cops are left off the beat.

As I write, crude oil is flowing into the Mississippi and a gas leak in Alaska’s Cook Inlet is ongoing, and has been for more than 3 months.

Sea ice is making repairs impossible, underscoring again the unique challenges of oil and gas exploration in Alaska’s frozen and tumultuous waters…

Imagine paying $40 extra a month for Tumblr

That’s what is going to happen if we let Ajit Pai, the FCC chairman, go through with repealing Title II (AKA Net Neutrality).

Simply put, without Net Neutrality, Internet Service Providers like Comcast, Verizon, and AT&T will be able to “bundle” websites much like cable ON TOP OF paying for internet connection. “Want access to Netflix AND Tumblr? Get the Entertainment Package! $40 a month. What about Amazon and Ebay? Add an extra $20 a month to get the Shopping Package.”

Not only will they be able to bundle websites and charge more, they will also be able to censor and block websites that they don’t agree with entirely.

THIS WILL BE THE END OF INTERNET AS WE KNOW IT.

For business owners, it will be even worse. Ex: Comcast will ask Amazon to pay high fees to be available in a low-cost package, fees that websites like Poshmark or Etsy will not be able to pay. Therefore, only Fortune 500’s will be available to web users at a low cost. Say goodbye to Etsy (unless you’re willing to shell out $70 a month for the “All-Inclusive” package).

There are five people deciding the future of the internet, three men (Rep) and two women (Dem). The two women have come out as No votes. We need only to convince ONE of the other members to flip to a NO vote to save Net Neutrality.

Most importantly, VOTE. This should not be something that is so clearly split between the political parties as it affects all Americans, but unfortunately it is.

7 Sports Astronauts Love Without Gravity (Including Football)

Astronauts onboard the International Space Station spend most of their time doing science, exercising and maintaining the station. But they still have time to shoot hoops and toss around a football.

From chess to soccer, there’s a zero-gravity spin to everything.

1. Baseball

Baseball: America’s favorite pastime. JAXA astronaut, Satoshi Furukawa shows us how microgravity makes it possible to be a one-man team. It would be a lot harder to hit home runs if the players could jump that high to catch the ball.

2. Chess

Yes, it’s a sport, and one time NASA astronaut Greg Chamitoff (right) played Earth on a Velcro chess board. An elementary school chess team would pick moves that everyone could vote for online. The winning move would be Earth’s play, and then Chamitoff would respond. About every two days, a move would be made. But who won the historic Earth vs. Space match? Earth! Chamitoff resigned after Earth turned its pawn into a queen, but it was game well played.

3. Soccer

NASA astronaut Steve Swanson put a new spin on soccer by juggling the ball upside down. However, he might not have considered himself upside down. On the space station, up and down are relative.

4. Gymnastics

NASA astronauts usually sign off their videos with a zero-gravity somersault (either forwards or backwards). But astronauts are also proficient in handstands, flips and twists. The predecessor to the International Space Station, the Skylab, had the best space for the moves. The current space station is a bit tight in comparison.

5. Basketball

Objects that aren’t heavy don’t move very well on the space station. They kind of just float. It’s like Earth, but exaggerated. For example, on Earth a beach ball wouldn’t go as far as a basketball. The same is true in space, which is why playing with a basketball in space is more fun than playing with a beach ball.

6. Golf

People talk about hitting golf balls off skyscrapers, but what about off the International Space Station? While golf isn’t a normal occurrence on the station, it’s been there. One golf company even sent an experiment to the station to find out how to make better golf clubs.

7. Football

Zero gravity doesn’t make everything easier. Astronauts need to relearn how to throw things because their brains need to relearn how to interpret sensory information. A bowling ball on the space station no longer feels as heavy as a bowling ball on Earth. When astronauts first throw things on the space station, everything keeps going too high. That would put a wrench in your spiral for a couple of months. But once you adjust, the perfect spiral will just keep spiraling!
