NASA’s Astronomy Picture Of The Day: The Milky Way From A Malibu Sea Cave

NASA’s Astronomy Picture Of The Day: The Milky Way From A Malibu Sea Cave

From NASA:

Explanation: What’s happening outside this cave? Nothing unexpected – it’s just the central band of our Milky Way Galaxy passing by. As the Earth turns, the band of our Galaxy appears to rotate and shift along the horizon. The featured image was taken by a photographer who professes a passion for locating sea caves, and who found this spectacular grotto in Leo Carrillo State Park near Malibu, California, USA. After some planning, he timed this single shot image through the 10-meter high cave entrance to show the Milky Way far in the distance. In the foreground, several rocks about one meter across are visible. Visible in the background starscape are millions of stars including the relatively bright and orange Antares, situated just to the right of the image center.

What Happens To Your Body In 24 Hours?

As soon as you wake up, you’re tired and groggy. Depending on your age, you may find yourself more alert early in the morning or later in the afternoon. In a recent AsapSCIENCE episode, they cover the different phases your body goes through within 24-hours from alertness and the best time to exercise to socializing and procreation.

Do We Have To Get Old And Die?

Animals like the naked mole rat, rockfish, and lobster don’t age, but we humans do. Why? Henry from MinuteEarth gets into the science about aging and how naked mole rats repair their telomeres. Even if humans were able to, we would have problems with cancer whereas many of these animals are immune to it.

We’re not exactly sure how these species do it, but their anti-aging secret may have to do with their ability to rebuild the DNA caps on their chromosomes. These caps, called telomeres are one line of defense against aging in many species. That’s because cells need to divide to replace old or dysfunctional cells, but each time they replicate, they lose a little bit of DNA from the end of the chromosome. Normally that doesn’t matter since these lost bits come from the telomere end caps that don’t encode important information. But after many replications, the telomeres get trimmed so short that the cells can’t afford to lose anymore DNA, and they stop replicating.

The Evolution Of Nintendo Controllers

The History of Nintendo is defined by its wacky controller designs. From the NES to the WiiU, nearly every new generation of console brought some new way to control their games. The NES had the D-pad, the SNES had shoulder buttons, the N64 had the Z-Trigger, and so on. But why? Why do we find such innovate use of controls in Nintendo and not in Sony or Microsoft? Join Jamin on this week’s episode of Game/Show as he answers the question and looks at the incredible history of Nintendo’s controllers!
