Reply to comment by Lucky_Pyro in A new study suggests that too much screen time during infancy may lead to changes in brain activity, as well as problems with executive functioning — the ability to stay focused and control impulses, behaviors, and emotions — in elementary school. by Wagamaga

Agreed! I don't think all children shows need to be "educational". But, the bonding and interactive aspect seems significant.

So are the cognative issues due to the screen time? Or is it a lack of active interaction and bonding?

Parenting is tough, so I can imagine parents hand off their tablets or turn on the TV to get some quiet time. But, sounds like we need to figure out better ways to make that screen time interactive.

Reply to Earth's inner core seems to be slowing its spin according to new research published in Nature Geoscience. The study authors suggest this might be part of an approximately 70-year cycle where the core speeds up and slows down relative to the rest of the planet. by shiruken

Does the effect the earth's magnetic poles? I saw an article last year that the true North has shifted over the last couple years, which appears to also be a part of a normal cycle.

Reply to comment by redditloginfail in Meditation works as well as a popular drug to reduce anxiety, study finds by AmethystOrator

I believe for a lot of people, meditation brings attention to anxious/traumatic thoughts. It's tough to move through that if you don't have the proper guide or tools. For these people, it could be more helpful to focus on more body centered, bottom up approaches that work with bodily sensations, rather than top down that focuses on cognition. Hiking and biking with noise cancelling earphones have been my go to...people don't think of this as meditation, but it's been great for me because the physical exertion prevents me from dissociating off into mental spirals.

Probably the same reason why talk therapy is not as effective for people diagnosed with ADHD. They need more body centered approaches.

Reply to comment by [deleted] in Cooperative sperm outrun loners in the mating race. In simulated reproductive tracts of animals like cattle and humans, the behavior increases the chances that groups of cooperative bovine sperm will outpace meandering loners as they race to fertilize a female egg cell, physicists report. by MistWeaver80

Agreed. Without the presence of an egg in this experiment, it's really tough to make any conclusions outside of sperm motility. Apparently, the egg chooses the sperm in natural environments. Recent studies are suggesting that even though the fastest and most capable sperms reach the ovum first, it is the egg that has the final say on which sperm fertilizes it.
