3 Extreme Ways Trees Survive the Winter

SciShow - 2020-03-05

Animals have all kinds of adaptations to help them get through winter, from hibernation to boots and hats. But trees have to make it through the coldest months of the year alive, too, and they've developed some pretty extreme ways to do it!

Props to the scientist that wrote the grant proposal for putting various trees in liquid helium.

TheOutrageousZ - 2020-03-07

@Solar Wind Ah, thank you for the info!

Solar Wind - 2020-03-07

@TheOutrageousZ You're welcome :)

Jared Maddox - 2020-03-08

@Gordon Lawrence : The earliest inkjet I know of was the rather specialized "siphon recorder", an 1800s device invented by Lord Kelvin, it was a constant-flow device that was used to record signals from the first trans-atlantic cable, due to the ability to use the minute electric charges to redirect the stream of the jet when seemingly nothing else was sensitive enough. The first commercial units were released by Seimans in 1951 for the medical field: they're more suited to industrial than office or home use, as the continuous flow allows more volatile solvents to be used, but also increases the evaporation of the solvents regardless of their volatility.

The drop-on-demand inkjet was itself invented in 1977 instead of the 80s, but is otherwise what you're thinking of.

Gordon Lawrence - 2020-03-08

@Jared Maddox I am quite aware of continuous flow printing and technically it is not inkjet as the individual droplets are not propelled. I worked as the senior tech for Lynx Printing with their top design engineer in the 90's when they were doing a complete re-design. The parts of the technology you are missing out are the ultrasound transducer at the flow head to produce consistent droplet size, the high voltage on the droplets to enable them to be electrostatically deflected, the sensor to measure charge on each droplet, and the def;ection plate to deflect droplets into the return trough.. Hardly something that could be easily used in the home.

NegativeZero - 2020-03-18

I am pretty sure it was probably the result of a bet he made with the guy that put a tree in liquid nitrogen, asking what he got if he did one better

YCCCm7 - 2020-03-06

Michael can't keep a straight face trying to rationalize the backstory behind trees and liquid helium. 10/10

Vectored Thrust - 2020-03-05

Love Michael breaking the presenter character and laughing at the absurdity of dunking a tree in liquid helium

Charles IV of France, anyone?

Beskamir - 2020-03-06

I mean, technically humans can become glass... just the process isn't particularly reversible.

Ieuan Hunt - 2020-03-06

Reminds me of King Charles IV of France. He thought he was made of glass.

cfltheman - 2020-03-06

Sounds like a power for a super hero or villain.

Chris Heichel - 2020-03-07

Bodies found at the area of Mount Vesuvius coated in ash parts of their brains were found to be Glass

Edit : More accurately it was a cavity in the ash that was body shaped where the body used to be. Most of it had been vaporized but some of it was turned to glass, specifically the brain for some reason.

artchic528 - 2020-03-06

Anyone else find Michael's voice soothing and relaxing to listen to? Just me? Okay....

Line Fortier - 2020-03-06

I love his voice and I found him the prettier.

mokovec - 2020-03-07

Is it just me or is his voice similar to Hank's?

BertyFromDK - 2020-03-09

@mokovec Just you, i think 🤔 His dynamic demeanour, on the other hand, is similar to Hank's.

jacqueline schael - 2020-04-07

I definitely prefer him over the other guy, the hyper one that talks annoyingly fast.

Fallout - 2020-09-07

@jacqueline schael I personally enjoy his hyperactive excited personality. Now, you would absolutely despise the newer girl, who apparently doesn't realize what a coma or period is to break a sentence.

Don Fields - 2020-03-05

I have experienced trees "exploding" at both extremes, in the bitter cold in VT and in a massive wildfire in CA, and in wildfires its a true complete explosion. Crazy

suicune2001 - 2020-03-06

I've never seen a tree explode. O_O

Evil Sharkey - 2020-03-06

Positive lightning bolts do a pretty good job of it, too.

AtarahDerek - 2020-03-06

Here in Montana, there were reports of trees exploding at Roger's Pass when the temperature dropped to -70°F.

21Stryfe - 2020-03-06

I'm from Canada and it's pretty common at say -50c or so

Chris Heichel - 2020-03-07

Never seen it first hand but I've seen videos and it really is awesome and amazing to see

funkeybikemonkey - 2020-03-05

why don't they just shiver like us. i find having a good old fashioned moan helps too. stooopid trees!

funkeybikemonkey - 2020-03-06

@HenryManson ohh my gosh, bet you're fun at parties. I know it was a silly joke. Not a funny one. Cold though in it!

HenryManson - 2020-03-06

@funkeybikemonkey does "shake your tree to get warm until he blooms" better to you then?! excuse me, for being serious sometimes!

funkeybikemonkey - 2020-03-06

@HenryManson way better! Or they could just up root and leaf to go on holiday somewhere warm. 😊 Hehe seriously serious is fine I think the only place I'm not serious is online.

Madaragun - 2020-03-10

You moan when your cold? What a weird human

KissOfDanger - 2020-03-11

@clxwncrxwn Cypress trees.

Cody'sLab - 2020-03-06

Question. What happens if you freeze a tree with liquid nitrogen and stored it for several years then brought it back to room temp? What about a million years?

Fallout - 2020-09-07

That question right there is precisely why you should be using your time theorising, and experimenting through science.

Terry Maximum-Effort - 2020-03-05

How do you look younger now than when you started presenting??

Also, when you said about sometimes having too much helium... I bust out laughing, because that is exactly what I would have done as a kid!!

Suq Madiq - 2020-03-06

@Terry Maximum-Effort that's an opinion I hold myself.

Anarchy Antz - 2020-03-06

They dip him in liquid Helium in between presentations locking in the human freshness. When it is presentation time, simply pop him in the microwave for three minutes.

Terry Maximum-Effort - 2020-03-06

Anarchy Antz now that’s an answer I’ve been looking for! Lol

Peter Houle - 2020-03-06

Tim Sullivan - 2020-03-05

With the tree's survival depending on them completing the vitrification process before that critical temperature is reached, to avoid the danger that differences between Fahrenheit and Centigrade might confuse trees - with lethat consequences! So it was decided to make it so that the critical temperature - minus 40 degrees - would be identical in both Centigrade and Fahrenheit! Good thinking!

Bader Alaraimi - 2020-03-05

We need to learn from those trees to achieve cryosleep

4:08 - Probably my favorite moment in a SciShow vid in a long time. Your delivery is so on point!

Julia Naylor - 2020-03-05

Some of these trees that survive low temperatures, could be some of the species that survived the winter conditions, caused by the Ice Ages.🌳🌲

Gordon Lawrence - 2020-03-06

Most of the planet was nothing like -50C even when it was at it's worst. The average temperature globally was only about 8C colder than it is now according to NASA.

Master of Mundus - 2020-03-08

@Gordon Lawrence Average or median? Important difference. Especially considering all the trees mentioned are native to the coldest places on earth.

Gordon Lawrence - 2020-03-08

Mean average is what is meant in normal conversation when the type of average is not mentioned. Median average is almost never used for weather (I cannot find a singe instance of it's use) and modal average is used extremely rarely.

Maple Hufflepuff - 2020-03-06

You forgot to mention that in extreme cold, trees can explode. It happens when the sap freezes
A tree exploding can sound like a gunshot and it's dangerous to be nearby them when they do. ❄🌲💥

Mossflower - 2020-03-06

Another video about something trees do that is pretty incredible, something most people never really question: how can trees grow so tall?
https://www.youtube.com/watch?v=BickMFHAZR0
You can even see Hank in the video as one of the people that try to give an explanation.

Nick B - 2020-03-06

The thumbnail mentioned trees turning into glass, and I watched the whole video waiting for an explanation. I was disappointed with the brief splash of jargon. I wound up having to re-watch the segment, and then research it off site, to get a picture of how what the trees do count as turning into glass.

Tim Sullivan - 2020-03-05

Seems clear that some trees are working at being able to survive WHATEVER extreme conditions might result from our planet-trashing ways. My guess - they're working towards being able to survive inter-planetery space. It would serve us right if the trees colonized Mars, leaving us behind on a doomed Earth.

Redmoon383 - 2020-03-06

@Tim Sullivan 0/10 reply, no wink-y face ;P

Mary Sue - 2020-03-06

@Tim Sullivan No, using a thesaurus won't make you look smarter.

Tim Sullivan - 2020-03-06

@Mary Sue Dont think I've said anything that could be construed as having supported such a claim so I have absolutely no idea why you made this comment. But by all means, do tell.

James Burleson - 2020-03-06

@Michael Esposito Oh the CO2 levels have certainly been higher, but they've never changed so rapidly. The geological and biological processed that have changed things in the past have done so at much slower rates, usually on the order of thousands of years. It took millions of years for all the carbon locked in the oil to be sequestered, and we've released it in a couple of hundred years, and nearly doubled atmospheric CO2 in the process. The planet does have a lot of inertia with things like temperature, but it can't handle massive shocks like we've done, hence the rapidly changing climate and erratic weather we're starting to see. Ocean temperatures are rising, and there's a whole hell of a lot of thermal mass in the ocean, so if that goes up by 10 degrees worldwide, that's an unimaginable amount of thermal energy the planet has trapped in a very short time, geologically speaking.

Andrew Nel - 2020-03-29

Calm down. This planet has been going through extremes of hot and cold since before there were life.
Also, Corona Lockdown.

I'm REALLY interested to know how the researchers explained wanting to dunk living trees in liquid helium. It sounds like a drunken dare, but liquid helium being no joke and not quickly obtained...

Ok so let’s take some trees to titan 😂

Semmelein - 2020-03-15

That helium joke was hilarious! 😂

The first life on this planet was plants. The first special adaptations of this wonderful world!

sdfkjgh - 2020-03-06

4:19 So, if the wood's been vitrified, can you make a knife out of it, and how well will it hold an edge?

Mary Sue - 2020-03-06

Was that in reference to the Japanese asmr knife dude with the cucumbers?

sdfkjgh - 2020-03-06

Mary Sue: No, it's an actual, serious, sincere question.  I've seen people attempt to make glass knives before (including forging an obsidian knife), so I was wondering about woodglass.

Mary Sue - 2020-03-08

@sdfkjgh Oh, in this case I have absolutely no idea. But since this phenomenon occurs only at low temperatures it would be difficult to really do something with it. It would probably feel like working with a mixture of wood and ice, I imagine not that special since the general structure of the wood stays the same.

Chris Heichel - 2020-03-07

I just read an article about how they're growing plants on the space station I'm wondering how tall a tree could grow and also how it would grow.
Here on Earth there's a limit to the heights of trees because of gravity. The trees can't pull the water all the way up to the top after a certain height. Around the upper 300s lower 400s of feet

OBK - 2020-03-07

Chris Heichel what about mars bring redwood seeds for the first super domes

Chris Heichel - 2020-03-07

@OBK I don't know the exact math and I'm just guessing here but with Mars gravity you'd probably end up with a tree that's 600 700 ft tall that would be insanely awesome

bitsnpieces11 - 2020-03-06

When he's talking  about cells bursting when they freeze rapidly reminds me of stories about making noises like exploding bombs in Nordic and Siberian areas during winter.  I guess it's the result of the cells bursting.

Master of Mundus - 2020-03-08

Huh, I've only ever heard that from my doctor about his hunting trips to Montana. I guess it must be the same at all the similar climates

Deanna W - 2020-03-06

“Luckily for the vast majority of the world’s surface, this limit isn’t important” (pained Minnesotan laughter)

Chris Heichel - 2020-03-07

If you've ever seen a tree explode because of an extreme cold drop in temperature it's really freaking awesome.

heyou - 2020-03-06

As far as I am aware, there is no correlation between a fluid's viscosity, and it's freezing temperature. Further so, this is a slippery slope when the liquid in question is water, for the freezing point depends solely on the pressure, and the amount of dissolved ions, which may vary in the amount which each specific type of ion affects the viscosity when being dissolved in water.

Master of Mundus - 2020-03-08

I think you just described all freezing points, not just water. The metal at the center of the earth does the same thing.

Tim Sullivan - 2020-03-05

4th tree strategy was successfully used long ago by the Canadian Coconut Palm - go south for the winter and apply for permanent residency.

John Larson - 2020-03-06

when I use to live in Vermont years ago when the temp went to to minus 35 below zero . the trees burst and cracked in half.
