The Nobel Prize for physics in 2011 was awarded to Brian Schmidt, Adam Riess, and Saul Perlmutter for discovering that the universe is expanding at an accelerating rate. This finding was completely unexpected because it was thought that gravity should slow the expansion of the cosmos. The best current explanation of why the universe is accelerating is that there is some energy tied to empty space which pushes matter apart. This 'Dark Energy' makes up 73% of the universe but is very difficult to detect. Hopefully a better understanding of it will lead to a unification of our theories of gravitation and quantum mechanics.

Lyrics:
How could I throw away a miracle?
How could I face another day?
It's all of my doing, I made a choice
And today, I pay
My heart is full of pain
How could you understand, the way I feel?
How could you relate to so much pain?
Seems as though nothing can comfort me
So today, I pray
That someone should listen, for...
Nothing should matter
Not when love grows inside you
The choice is yours
There's a miracle in store...
Nothing should matter
Not when love grows inside you
A voice of love is crying out
Don't throw love away
There's a miracle in store...

Well, it wouldn't be too long after we started developing Ecology that we would try to control the environment. In some ways this was helpful and likely prevented a lot of people from starving. But, there have been a few downsides.

Earwigs are equipped with some pretty imposing pincers on their rear, and they're not afraid to use them. But when it comes to these appendages, size isn't everything.

DEEP LOOK is a ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small.
Many animals seem to show a preference for symmetry in a potential mate. It can be a clue that the mate has the genes necessary to develop properly and thrive in an environment full of stresses and dangers.
But in some critters buck the trend. Like the earwig, a diminutive insect found on every continent except Antarctica.
Andrew ZInk, an associate professor of biology at San Francisco State University, has been looking at how symmetry affects earwigs success when it comes to social interactions.
He’s studying maritime earwigs, a larger and more powerful cousin to the common European earwig you might find in your backyard. Both creatures bear fearsome looking pincers on their backsides. And they aren’t afraid to use them to defend themselves. Zink knows all about that.
--- Do earwigs climb into your ear?
The quick answer is no. Earwigs are not interested in climbing into your ear to lay their eggs or otherwise. They’re no more likely than any other bug to accidentally find its way into you ear. The name earwig come from the old english words for ear and insect. It may have been named after the shape of the common European earwig’s wings, which when extended resemble a human ear.
--- Do earwigs pinch people?
Earwigs will use their pincers to defend themselves, but the pinch is typically not strong enough to be considered dangerous.
--- Do earwigs fly?
Male common European earwigs have wings and can fly to disperse and find mates. Females do not have wings or fly. Neither male nor female maritime earwigs have wings or fly.
--- What do earwigs eat?
Most earwigs are scavengers and omnivores. In addition to scavenging and eating plants, the common European earwigs also hunts small prey like aphids. Maritime earwigs are carnivorous hunting smaller arthropods like sand hoppers.

It is a common view that "if only someone could break this down and explain it clearly enough, more students would understand." Khan Academy is a great example of this approach with its clear, concise videos on science. However it is debatable whether they really work. Research has shown that these types of videos may be positively received by students. They feel like they are learning and become more confident in their answers, but tests reveal they haven't learned anything. The apparent reason for the discrepancy is misconceptions. Students have existing ideas about scientific phenomena before viewing a video. If the video presents scientific concepts in a clear, well illustrated way, students believe they are learning but they do not engage with the media on a deep enough level to realize that what was is presented differs from their prior knowledge. There is hope, however. Presenting students' common misconceptions in a video alongside the scientific concepts has been shown to increase learning by increasing the amount of mental effort students expend while watching it.
