Sperm Movements Captured in 3D for the First Time Reveal "Swimming Strokes" (Video)

Scientists have tracked down the paths of sperm in 3D. Now we get to see how they move and the patterns that they make. How do they do it? In a corkscrew like pattern and are hyperactive and hectic. Sperm has swim strokes!
According to Aydogan Ozcan, the study leader, his team placed sperm on a silicon sensor chip and shone red and blue LED lights from different directions onto them to track their movements and plot out their path in 3D. Here's what they found out:
The vast majority of the sperm followed a "typical" path-more or less a straight line.
But some swam in a helical, or corkscrew, pattern previously only hinted at by fuzzy microscope results. Other sperm were labeled "hyperactive" due to their jerky direction changes, which sometimes sent them careening in reverse.
Check out the video below. Scientists do not know the differences in these swimming strokes just yet. Maybe the ones that really want to make it are relentless hence the crazy way of getting where they want to be. [National Geographic]
The complaints about Apple's new bendable iPhone 6 Plus is making its rounds on social media, and here's a round up of all the jokes we've seen so far. Apparently, Apple is said to be replacing the bent iPhones if they pass the "visual inspection" and qualify for warranty replacement. Check out the jokes: Read more
Here's an interesting video to check out, which goes into discovering whether or not periods make women moody. There's just so many chemicals floating around that we misconstrue that PMS = period. Which is not. Check out the video for more: Read more
