VetiGel: A Plant-Based Polymer That Stops Bleeding in Seconds

0vetigel001.jpg

I once got stabbed in the head with a wooden knife. It was an accident that occurred during a martial arts training exercise. I’d heard that head wounds bleed badly, but as I waited for the taxi to take me to the hospital (an ambulance is not what you take in NYC if speed is a priority) I was shocked at the amount of blood that came out of my head.

While head wounds are bad, severing a femoral or carotid artery is way worse in terms of blood loss. If you slice one of these open and can’t stop the bleeding, that’s basically the last selfie you’ll ever take. But now a tiny biotech company in Brooklyn can change that equation, having developed a product that stops bleeding, whether pinprick or grievous wound, almost instantly.

Called VetiGel, the material is a plant-based polymer. It requires no training to use and can be loaded into an ordinary plastic syringe; rather than needing to learn how to prepare a field dressing, someone providing aid can simply aim and squirt it like toothpaste onto a brush. Watch how it works in this video:

The leftover material, by the way, can be safely resorbed into the body or removed.

As for why it’s called VetiGel, the material is first being marketed towards veterinarians, with approval for human use planned for further down the line.

Should the product pass human trials and prove affordable enough to manufacture, it could be a real game changer: Simple syringes loaded up with the stuff and placed into every ambulance, soldier’s pack and first aid kit around the world could mean the difference between life and death for countless people, particularly those for whom a hospital is more than a cab ride away.

The process of turning raw cow hide into leather is really gross

The process of turning raw cow hide into leather is really gross

Leather is beautiful and luxurious and natural and one of the great materials of the world. However, it’s absolutely gross to make. Here’s the process of tanning raw hide into high quality leather. You’ll see gray goops, a lot of residue, dumps of bizarre liquids and more. Worth it? I guess.

Here are some of the grosser segments (which in turn, are my favorite segments). A lot of is turned into dog food.

This is how you fold the perfect paper airplane

This is how you fold the perfect paper airplane

I used to flip the end of the wings of paper airplanes upward and breathe on the head of the airplane to make it fly farther. According to John Collins—the maker of the paper airplane with the world record for the longest distance—I was doing it wrong. This video shows how to do it properly.

This is the video that shows how they broke the world record. Former Cal Berkeley quarterback Joe Ayoob is the guy throwing the plane.

If you want to learn how to make other great paper planes you can buy John’s books here and here.

How Guardians of the Galaxy should have ended

How Guardians of the Galaxy should have ended

Guardians of the Galaxy was one of the best movies of the year and probably one of the funnest movies I’ve seen in a long while but it also had its fair share of logic gaps that were glossed over. HISHE hilarious fixed the movie by changing some scenes in the movie so it all makes sense. Spoiler alert: the bad guys win.

And Here's a Treasure Trove of 90s Videos About the Internet 

Remember the 90s, when we had videos on VHS to teach us about this new thing called the internet? Lucky for us, Andy Baio (@waxpancake) has preserved those tapes for the YouTube generation.

Baio’s whole playlist is six hours long, but might we suggest you start with "Internet Power! Volume 1"? Discover The World of Online Entertainment!

Don’t worry, the thrilling conclusion of "Internet Power! Volume 2" is available too (below). Baio goes into a lot more detail about how he digitalized the tapes, a project he actually started years ago, over at his blog. And we’re while doing hyperlinks (a concept explained in Volume 1), here’s the whole six-hour playlist again. [via Kottke]

How to Unlock Hidden Settings In Your Favorite Software

How to Unlock Hidden Settings In Your Favorite Software

Not every app has a Settings menu that’s easily accessible. Sometimes, developers hide away debug menus, secret settings, and more. With them, you can unlock additional features or just get some crazy stats. Let’s take a look at some of the most useful among them.

Netflix Menus Unlock Statistics and Streaming Info

Netflix is great but it’s not without it’s problems. The buffering might be off, the playback might be slow, or the you might just have problems loading movies in general sometimes. The good news is that you can access a secret menu to help you with the problem.

On Windows, you can tap Shift+Alt+Left-Click (Shift+Option+Click on Mac) to load up the stream manager. This allows you to change your buffering or fix any sync issues.

On PS3 and XBox 360, you can access a secret menu by tapping in "Up, Up, Down, Down, Left, Right, Left, Right, Up, Up, Up, Up" on your controller. You’ll pull up the hidden diagnostics page where you can log out, enable special settings, and more.

Unlock Hidden Menu Options in Windows with a Shift+Right-Click

How to Unlock Hidden Settings In Your Favorite Software

Windows has a ton of different hidden menus accessible by tapping the Shift key when you right-click. Holding down the shift key can reveal extra options in the Send To menu like sending over to Dropbox, moving to the Desktop, and more. You can also instantly pin an app to the Start menu and open in a command window.

Access Hyperlapse’s Hidden Settings for Advanced Video Options

Instagram’s Hyperlapse app is a great way to make time-lapse videos, but it’s pretty short on actual settings. However, if you tap the screen four times with four fingers you’ll open up a secret menu where you can record in 1080P video, edit frame rate, and more.

Get Special Debug Menus In Address Book, iCal and Disk Utility

How to Unlock Hidden Settings In Your Favorite Software

Three of Apple’s stock apps have hidden debug menus where you can enable experimental options. Most of these don’t work on Mavericks or Yosemite, but if you’re running an older OS you should be able to enable them with some Terminal commands:

Enable the debug menu in Address Book (doesn’t work in Yosemite):

defaults write com.apple.addressbook ABShowDebugMenu -bool true

Enable the debug menu in iCal (Doesn’t work in Mavericks or Yosemite):

defaults write com.apple.iCal IncludeDebugMenu -bool true

Enable the debug menu in Disk Utility:

defaults write com.apple.DiskUtility DUDebugMenuEnabled -bool true

and

defaults write com.apple.DiskUtility advanced-image-options -bool true

The Disk Utility tricks work perfectly fine in Yosemite and Mavericks, but the rest won’t.

Access the Hidden USB Menu on a Windows Phone

How to Unlock Hidden Settings In Your Favorite Software

By default, you can’t get into the USB options screen on a Windows Phone. However, Windows Phone Central shows off a super simple way to access the hidden menu:

  1. Launch Bing or Cortana
  2. Type in ‘USB’
  3. Swipe left to ‘phone’
  4. Tap Settings > USB

You won’t unlock a ton of options, but you can enable a handy "Notify me when I connect to slower charger" alert.

Access Secret Signal Strength Stats on iOS

How to Unlock Hidden Settings In Your Favorite Software

If you don’t feel like the little dot indicators in iOS are useful in judging your cell signal, you can get to a hidden menu to get more information by simply dialing a phone number. Redmond Pie explains:

Step 1: Dial *3001#12345#* on your iPhone then press Call.

Step 2: You’ll now enter Field Test mode. You’ll notice a signal strength indicator on the upper left hand corner of your screen. You can toggle between signal strength bars and a number by simply taping on it. At this point, press the home button to exit the app or if you would like the feature to be permanent, continue on. Don’t worry, the process is completely reversible.

Step 3: Hold down on the Power button until you see the ‘slide to power off’ bar. Do not power off the device.

Step 4: Press down on the Home button until the app closes and you return to your home screen.

That’s it. Even when restarting the iPhone, the signal strength can be toggled between bars and numbers. The closer your number is to zero, the stronger your signal is.

Unless you’re a cellular wiz, then the menu itself probably isn’t that useful, but it’s still nice to know it’s there.

Load Up Apple’s Hidden Wi-Fi Diagnostics Tool

How to Unlock Hidden Settings In Your Favorite Software

Tucked away inside OS X is hidden Wi-Fi Diagnostics Tool that can help you fix problems with your network. Loading it up is pretty easy:

  1. Option-Click the Wi-Fi symbol in your menu bar.
  2. Select "Open Wireless Diagnostics"

That’s it. The app will open up and you can check out a ton of stats about your network.

Access CrashPlan Logs

How to Unlock Hidden Settings In Your Favorite Software

If you ever need to check out the error logs in CrashPlan, you can do so with their hidden menu. The process is pretty straightforward:

  1. Open the CrashPlan app.
  2. Double-click the CrashPlan logo in the upper-right.
  3. Enter: getlogs

This is meant as a way to grab your logs to send to tech support, but you might find it useful if you’re ever troubleshooting yourself.

Unlock a Ton of Options with iTerm’s Secret Settings

How to Unlock Hidden Settings In Your Favorite Software

iTerm is our favorite terminal emulator on Mac and it just so happens that you can enable a ton of new settings from the command line. There are way too many settings to list here, but here are a couple of our favorites:

To preserve whitespace in selections copied to the pasteboard:

defaults write com.googlecode.iterm2 TrimWhitespaceOnCopy -bool false

To change the number of paste history entries saved:

defaults write com.googlecode.iterm2 MaxPasteHistoryEntries -int 20

Head over to iTerm’s hidden settings page for a bunch more information.

Chrome’s Flags and Firefox’s About:Config

How to Unlock Hidden Settings In Your Favorite Software

Both Chrome and Firefox have special settings where you can enable a ton of hidden features. In Chrome, you can access it by typing in chrome://flags to the URL bar to get to the experimental features screen and in Firefox you can type in about:config. Both of these have far too many features to list here, but it’s worth poking around in the browser of your choice to unlock some cool hidden settings and menus.
