Is it possible to reconstruct sound from high-speed video images?

Special thanks to Dr. Abe Davis for revisiting his research with me: http://abedavis.com

This video was based on research by Dr. Abe Davis and colleagues. I found out about this work years ago and was fascinated by the way he was able to capture vibration information in image-only video. I always imagined the motions of objects would be visible as when recording a tuning fork in slow motion - so deriving sound from high speed images seemed a feasible task. But the reality is much more difficult.

Sound vibrations only cause objects to wiggle by about a micrometer. This is much smaller than a pixel, so the algorithm must understand the characteristics of the image. A move in one direction should cause some pixels to lighten slightly, while others darken - and this behavior is correlated along the edges of the image. So noise can be reduced because it's random over the image and there are enough places to sample that you can get it to cancel out.

Something I'm wondering now is - would it be possible to capture sound in a single image? I'm thinking it would have to be an image of a large object or space because the wavelengths of typical sounds are quite long. Maybe a high frequency sound could be imaged in a suitable medium...

Remarkably little is known about great white sharks, but they are similar to humans in a lot of ways - they give birth to live young, maintain a higher body temperature than their surroundings and they are apex predators. There are also many misconceptions about these sharks: people think they don't get cancer and that they reside mainly in shallow waters near beaches. In this video I summarize some of the most interesting things I learned about sharks on my cage diving adventure.

Chris Cassella or C² as he is known after this trip was a shark spotter extraordinaire. He also took some of the best shark footage in this video. It was his idea to go on this expedition, which was definitely a once in a lifetime experience, so I am in his debt. Chris, I look forward to going on more great adventures with you.

Every day in an adult human roughly 50-70 billion of your cells die. They may be damaged, stressed, or just plain old - this is normal, in fact it’s called programmed cell death.

To make up for that loss, right now, inside your body, billions of cells are dividing, creating new cells.

And cell division, also called mitosis, requires an army of tiny molecular machines.DNA is a good place to start - the double helix molecule that we always talk about.

This is a scientifically accurate depiction of DNA. If you unwind the two strands you can see that each has a sugar phosphate backbone connected to the sequence of nucleic acid base pairs, known by the letters A,T,G, and C.

Now the strands run in opposite directions, which is important when you go to copy DNA. Copying DNA is one of the first steps in cell division. Here the two strands of DNA are being unwound and separated by the tiny blue molecular machine called helicase.
It literally spins as fast as a jet engine! The strand of DNA on the right has its complimentary strand assembled continuously but the other strand is more complicated because it runs in the opposite direction.
So it must be looped out with its compliment strand assembled in reverse, section by section. At the end of this process you have two identical DNA molecules, each one a few centimeters long but just a couple nanometers wide.

To prevent the DNA from becoming a tangled mess, it is wrapped around proteins called a histones, forming a nucleosome.
These nucleosomes are bundled together into a fiber known as chromatin, which is further looped and coiled to form a chromosome, one of the largest molecular structures in your body.
You can actually see chromosomes under a microscope in dividing cells - only then do they take on their characteristic shape.

The process of dividing the cell takes around an hour in mammals. This footage is from a time lapse. You can see how the chromosomes line up on the equator of the cell. When everything is right they are pulled apart into the two new daughter cells, each one containing an identical copy of DNA.
As simple as it looks, this process is incredibly complicated and requires even more fascinating molecular machines to accomplish it. Let’s look at a single chromosome. One chromosome consists of two sausage-shaped chromatids - containing the identical copies of DNA made earlier. Each chromatid is attached to microtubule fibers, which guide and help align them in the correct position. The microtubules are connected to the chromatid at the kinetochore, here colored red.
The kinetochore consists of hundreds of proteins working together to achieve multiple objectives - it’s one of the most sophisticated molecular mechanisms inside your body. The kinetochore is central to the successful separation of the chromatids. It creates a dynamic connection between the chromosome and the microtubules. For a reason no one’s yet been able to figure out, the microtubules are constantly being built at one end and deconstructed at the other.
While the chromosome is still getting ready, the kinetochore sends out a chemical stop signal to the rest of the cell, shown here by the red molecules, basically saying this chromosome is not yet ready to divide
The kinetochore also mechanically senses tension. When the tension is just right and the position and attachment are correct all the proteins get ready, shown here by turning green.
At this point the stop signal broadcasting system is not switched off. Instead it is literally carried away from the kinetochore down the microtubules by a dynein motor. This is really what it looks like. It has long ‘legs’ so it can avoid obstacles and step over the kinesins, molecular motors walking the other direction.

Inspired by the Rosetta Mission, an extraordinary and ground-breaking project by the European Space Agency [ESA] to land a probe on a comet for the first time in history, Vangelis has composed this suite of inter-connected music especially for ESA. The album marks the culmination of the 12-year mission in September 2016 and accompanies some incredible footage captured by the probe.

“Mythology, science and space exploration are subjects that have fascinated me since my early childhood. And they were always connected somehow with the music I write.” – Vangelis

Head east at Santo Domingo and after a few hours drive you'll end up in the south. Down here you'll see all the things you'd expect in the deep south: deserts, swamps, gators…. Wait, wrong deep south.

But actually not that far off. This is indeed desert area, and while there are no gators, there are crocodiles... But we’ll talk about them in another video.

Because of the desert the area is sparsely populated and most communities center around specific areas of geographic or industrial importance. Still, there are a lot of interesting locations far off the beaten tracks worth a visit.

But today we wanted to visit one thing that doesn't usually count as a tourist attraction, and for remote places down south i turned to a local expert and one of the foremost guides to the area: Mike. He also happens to be my little-big brother… Or big-little brother. You decide which is which. We like to keep people guessing.

It's called a Haitian market since it sells Haitian products. Except they're mostly not Haitian products. I mean, you'll find some local produce and products of course, but for the most part it's actually a secondhand market, or flea market if you will.

You see, for over 50 years the world has been pumping aid into Haiti, which has not just served as a moral placebo for the world, but does actually do something: it's created a whole economy of its own, that of the used clothes and items market. You know what they say: one man's trash is another nation's economy. Or something like that.

Donated and used clothes that end up in collections in the more, shall we say wealthy nations, are packed and shipped to developing countries worldwide: Haiti for example. And here they are resold for dirt cheap. Seriously, you can get used clothes for a fraction of a fraction of what you would pay for them new. But they're not just resold within Haiti: a large amount is taken outside the Haitian border and resold to Dominicans -- in the case of the Pedernales Haitian market literally just a few feet from the border. Here anyone can then rifle through these, buy a few or a whole bunch and then resell them again somewhere else on the island. If you thought your free donations are given for free to someone somewhere, you've been sadly misled. For the most part all donated things are at some point sold and resold, even if it's just for a few cents on the pound. Even so, the point was for them to help someone, right? Well, by creating this economy, someone got a job and was able to make some money and feed their family. And that was the whole point, right?

Speaking of which, what about visiting Haiti? Could I just go ahead and visit Haiti by myself, outside of the antiseptic resorts and cruise ships?

While I don't need a broom, I heard of something very elusive - Haitian rum. It is rumored to be one of the best rums in the world, and I want to know if that is true. It's not available in the DR, but you can find the odd bottle here on the market. You just have to look.

My verdicts is that it really is the best rum I’ve ever had. Not sure the best in the world since I haven't tried them all yet, but it seriously is delicious. Especially Bakara Kanel, with its hint of cinnamon flavor. If you can get it, try it. But you may have to go to Haiti to find it or at least to the border...

No Blue Thing is Ray Lynch's fourth studio album, released on August 15, 1989. It peaked at #1 on Billboard's ''Top New Age Albums'' chart as well as #197 on Billboard's ''Top 200 Albums''. The album also peaked at #16 on Gavin Report.

Keith Tuber of Orange Coast praised the album, commentating that Ray Lynch ''has a way with melodies, combining classical, acoustic and synthesized pop elements.'' JA of Keyboard noted that the some of the album is ''more of the same'' from Deep Breakfast; JA wrote that the ''DX patches have a little more bit[e] this time, but the trick of running staccato patterns through a delay line in triplet rhythm hadn't changed'' and that the album, like his previous works, lack percussion instruments. JA concluded that the listeners may or may not like the album. Robert Carlberg of Electronic Musician compared the album to Reed Maidenberg's Unexpected Beauty, praising the album for its combination of electronic and acoustic instruments but criticizing it for having an overreliance of arpeggiations as well as its use of ''plodding'' time signatures and for its ''warm, fuzzy'' instrumentation. Carlberg concluded that the album's flaws ''rob [both Lynch and Maidenberg] of whatever vitality classical training would bring.'' John Diliberto of Jazziz Magazine criticized the album, calling it formulaic and concluded that the album ''breaks no new ground''. Gavin Report wrote that each track on the album is worthy of the listener's attention, especially ''The True Spirit of Mom & Dad'', which was described as the ''climactic final track'' of the album.

- Jarabacoa Flower Festival -

Once a year all of Jarabacoa comes out to for a big party: and it’s the Jarabacoa Flower Festival. It originated with the Japanese immigrants. But Jarabacoa has always been well known for its flowers. Due to its mild climate Jarabacoa became on of the central points on the island for growing flowers that aren’t as common in other places on the island.

Orchids for example are a flower that is not unique to Jarabacoa, but pretty common here, especially in the wild. This fact, plus the Japanese immigration in the 50s that encouraged the growing and exporting of flowers, turned Jarabacoa into the a pivotal point for anything that grows with more colors than just green. The event lasts for 4 days, usually towards the end of June. It always sets up somewhere around the Jarabacoa avenue.

So what can you do here? Well, besides buying flowers at special offers, you can indulge in just enjoying a stroll through what we'll call a tiny state fair. A month earlier they even elect a Queen of the Festival who then represent the town in other event throughout the island. For the most part the festival is visited by Dominicans, but you will also see the odd foreigner. They're easy to spot, especially if they're Americans: they're pretty much the only ones wearing shorts. True, it's a stereotype, but the evidence ain't helping the argument.

You can eat, buy artisanal decorations, jewelry, various exhibitions, enjoy free coffee and free concerts. During the day there are presentations by local artists and in the evening more nationally known artist show up for a few sets of their more popular songs. Dancing is optional.

There is a cover charge of 10 pesos per day, which is about 20 cents. Saturdays has the flower parade, an event that also features — besides floats, bands and cheerleaders — Jarabacoa's second indulgence: horses. People come from all over the island joining in the cabalgada: a cavalcade, or procession of horsemen, along the Jarabacoa avenue. You'll get to see several million dollars worth of paso fino horses riding down the street. That in itself is quite the impressive show. I mean, most of us can imagine a car worth being a million bucks, but a horse?

Now granted, by most standards the Jarabacoa flower fair is kind of small. Then again, Jarabacoa is still a village aspiring to become a town. It has no industry, but does rely almost entirely on agriculture, exporting vegetables, coffee and, well, flowers. The festival has only been going on for about 6 years, but it has been growing consistently.

So if you're in town and got an afternoon to to spare, swing by.

A planet has been predicted to orbit the sun with a period of 10,000 years, a mass 5x that of Earth on a highly elliptical and inclined orbit. What evidence supports the existence of such a strange object at the edge of our solar system?

I had heard about Planet 9 for a long time but I wondered what sort of evidence could support the bold claim: a planet at the very limits of our ability to detect one, so far out that its period is over 60 times that of Neptune. The planet 9 hypothesis helps explain clustering of orbits of distant Kuiper belt objects. It also explains how some of these objects have highly inclined orbits - up to 90 degrees relative to the plane of the solar system. Some are orbiting in reverse. Plus their orbits are removed from the orbit of Neptune, the logical option for a body that could have ejected them out so far. The fact that the perihelion is so far out suggests another source of gravity was essential for their peculiar orbits.

If you spin a raw egg and then stop it, it will start spinning again without you having to touch it. A boiled egg, on the other hand, stops and stays stopped. Why is this? Well a raw egg contains a yolk that moves inside the egg independently of the shell. If you stop the shell, the yolk inside continues to move due to its inertia and it therefore gets the egg spinning again.
