Hey there folks! Got another bumper crop of science for you, so let’s dig in!

As usual, we will be talking about brains, energy, tissue engineering, and miscellaneous cool stuff.

Random Cool Stuff

First off, a story just too damned cool not to cover : using ballistic missiles to deliver aid.

Can you imagine? People are trapped in a war-torn, drought-ridden area. Their lives hang in the balance. Nobody can get aid to them without risking being killed in the crossfire.

But then, a streak on the horizon…. a flash of hope… then a mighty roar as the missile streaks to its destination, shedding parachute crates of food, water, and medical supplies as it streaks overhead too fast for the eye to follow.

That would be damn near religious, man. Like manna from heaven.

Tissue Engineering Frontiers

Some page the Tin Man, because this article tells you how to build a brand new heart .

Well, sort of. Like a lot of these frontiers of tissue engineering stories, the process they are talking about does not exactly create a new heart from raw ingredients.

You still need a heart (or spleen, or whatever) to start with. Then you wash away all the active cells, leaving just the protein scaffolding behind, which you can then populate with lab-grown cells from the potential recipient of the transplant.

Which is still awesome. You are taking a foreign donor heart, which would cause a massive rejection response, and turning into a cell-perfect host heart which will be genetically indistinguishable from the recipient’s real heart.

So I merely quibble. It’s not really making a heart in the lab if you have to start with a heart in the first place. The real magic will be when we figure out how to make that scaffolding build itself.

These people are taking a step in the right direction.

They are working on a 3D system for growing someone a new pancreas, something near and dear to my… duodenum, as I might need a replacement some day.

The 3D is the key aspect here, because one of the major things holding back tissue engineering for generations was our POV being stuck in the 2D world of our microscopes.

But cells, organs, and organisms grow in three dimensions in the real world, and the flattened 2D world of the microscope slide just does not cut it any more.

The pancreas builders are using a gel to suspend and nourish the cells, and this gives the cells a chance to grow in the three dimensional way.

Now THAT is more like it!

Alternative Energy News

The main problem with solar power is obvious : what happens when the sun goes down?

A major solar plant in Arizona has that problem at least partly solved.

This plant can continue to produce power for six hours after the sun goes down via a thermal storage technology that the article is weirdly reluctant to explain. Perhaps it’s a big time trade secret.

But six hours seems like enough. After all, a) even at the winter solstice, that’s half the night covered, and b) people tend to use a hell of a lot less electricity when they are asleep.

So assuming people are cool with using battery powered alarm clocked, this is doable. Less then ideal, especially for us night owls, but doable.

Presumably, the thermal storage can be improved upon in the near future.

Then again, maybe all this thermal storage will be unnecessary because in the future, they can store the juice directly in massive molten air batteries.

Yes. That it seriously what they are called. What the fuck, right?

But they are called that because, unlike traditional batteries, they get their oxygen from the air, not from an oxidizer built into the battery. This makes them super light, which is a very big deal when you are looking for a battery tech for electric cars, and they also have a very high energy density.

Those two factors combined might just be enough to fuel the next big leap in electric cars. Have batteries that are lighter AND store more power?

That is just what the electric car industry needs. It could be just what the doctor ordered to give electric cars more power and more range at the same time.

And now… THE BRAIN!

A new theory of one of the functions of sleep has emerged.

This one starts from the observation that during sleep, the interstitial spaces between neurons increase by as much as sixty percent and there is a large fluid exchange. Protein laden interstitial fluid out, nice clean cerebro-spinal fluid in.

The theory is that this is the body’s way of flushing the nervous system clean, and that all those complex proteins going out are various plaques and other nasty stuff that we don’t need.

It is, literally, brainwashing.

We are constantly adding to our knowledge of the functions of sleep. We used to think sleep must be for one thing and one thing only.

But that would be like thinking all the employees at your local fast food place do after closing is clean the big grill.

No, they do everything that can’t be done when there’s customers there.

Finally, the Big Story. Proof that some people are just born negative.

The brain science is complicated and a tad dry. Genetics, neurotransmitters, and so on.

But I would warn this people against leaping to the conclusion that everyone with this particular gene variant is somehow sad or even clinically depressed. Most of them will be just fine.

The world needs both positives and negatives. The most productive creative and business partnerships have been between the positive person who comes up with tons of ideas and who provides much of the driving force, and the negative one who finds the flaws in the positive one’s ideas so they can correct them together, and who also acts as the necessary voice of restraint and caution.

My guess is that the world has around the same amount of each, and that’s no accident. Having that kind of diversity makes us stronger as a species.

And with that, I am off for the night. See you tomorrow, folks!

Another barrel of links

These things just spring up like weeds!

First we have this sobering and inspiring video.

Intellectually, somewhere in my memory banks, left there from my childhood, was the knowledge that, when I was nine years old, there was this thing called ERA that had not passed in the USA.

I think I thought it was a bill at the time, even though the word “amendment” is right in the name. But the point is, I knew this had happened.

But until I watched that vid, I did not realize just how fucked up that is.

Here in Canada, our Constitution has equality written right into it. So it never occurred to me that the situation was a lot more precarious down in the USA.

I can’t imagine a movement to pass the ERA now would fail, 31 years later. When it came up in 82, people were still arguing about whether husbands should let their wives work outside of the house.

We are so much further ahead now. Sure, the Tea Party types would reflexively oppose it, but they blew all their political capital on trying to stop Obamacare anyhow.

So really, who would argue with it?

Then we have snuggles for sale.

A bunch of ladies in Madison, Wisconsin are looking to start a professional cuddling service. For $60/hour, clients can go into private rooms and get professionally cuddled.

Needless to say, local authorities think that sounds just a little too much like prostitution to them, and so the ladies are having trouble getting a business license.

But the pro snugglers insist that all the rooms have cameras and will be monitored constantly to make sure that nothing more than cuddling goes on.

That’s all well and good. But a lot of fellows are going to start to have certain feelings while enjoying a nice cuddle with a gal, and at the very least the ladies will have to be experts in pretending there isn’t an erection poking them somewhere.

The rooms all have panic buttons, though, so if the fellas get too frisky, presumably all hell breaks loose.

Then we have this marvelous piece of work from the talented people at Bad Lip Read.

Man, they are getting good at what they do. They have learned that it’s funniest when it’s not totally random. Plus wow, now they have people that can Photoshop things into the backgrounds of videos fairly convincingly.

And more than that, this time they had a whole concept behind the piece that really takes their work to the next level. I found it was a joy to watch and just enjoy their increasing mastery.

Someday, they will re-dub an entire movie. And it will be awesome.

And speaking of the awesomeness, check out this new kind of display system :

The first thing I thought of when I saw that was “Help me Obi-Wan Kenobi… you’re my only hope!”.

But seriously, how “the future is now” is that? One of the things I am most looking forward to seeing in the future is all the science fiction of my childhood coming true.

We already have a lot of things, like cybernetics, nanotech, and real-time brain scanning via fMRI. Heck the USA even has a working large scale laser weapon at, of course, RIDICULOUS cost versus its actual effectiveness.

But when you tell a bunch of generals “We can build a laser cannon”, they just can’t throw money at you fast enough, because laser cannons are cool and surely if the enemy sees our awesome new laser guns they will be like “Damn, that is so much cooler than anything we have! We totally surrender. ”

That is seriously how these people think.

Anyhow, the mid-air display technology is, like the laser cannon, cool as hell, but I am not entirely sure what functional benefits it has. And at a price tag of $20K, you better be able to make some sort of halfway decent business case for it.

Granted, that business case might well be “this will impress the hell out of visitors, including potential investors, with how awesome we are. ”

I can see a lot of middle management types wanting one of them NOW NOW NOW, before that smug asshole over in Accounting gets one.

Then we have this impressive bit of craft which depicts an entire relationship in 5 minutes.

Warning, it’s very stagey, consists of just two actors talking to the camera, and is in black and white.

Why is it in black and white? Who knows. Maybe they thought it would make the whole thing seem more stark and emotional. Or maybe they were just being pretentious.

Regardless, I greatly admire the craft that went into it. It’s all one long shot, so the actors had to be really, really on their marks with every line, and there are a LOT of lines. And the writing is quite deft in the way ot gives you clues as to the passage of time in what they say, as opposed to having to introduce some artificial and obtrusive device that would have ruined the purity of it all.

I can’t say I really enjoyed the experience a lot, but I am impressed by how well it is made.

And then we have our adorable cat animated GIF of the day.

All cats are ninjas. Some just aren't very good ones.

All cats are ninjas. Some just aren’t very good ones.

I LOL’d so hard when I saw that. We cat lovers live for moments of feline comedy like that. Sure, it seems a little mean to laugh at them when they mess up like that, but most of the time they are so poised and agile and perfect that it just slays us when they do something goofy like that.

Especially when it’s one of their awe-inspiring “spring loaded cat” moments that goes awry. The speed at which we go from “coiled steel” to “where kitty go?” just makes the clip that much funnier.

Sorry, kittums. We love your little furry self so much. But sometimes, you’re hilarious.

I am sure we are pretty funny to you sometimes, too.

Finally, we have this little bit of rantiness I recorded today.

I feel good about that one because I managed to keep it under 5 minutes in length, after considerable trimming, and thus was able to keep my points fairly compact and concise. It also allowed me to concentrate more on putting in the extra stuff in order to punch it up a little.

After all, it’s a lot easier to come up with stuff for 5 minutes of video than for 15!
