We look at ourselves in the mirror on a daily basis. What are we thinking?

Is the hair ok?
Is the makeup covering all flaws?
Are my muscles showing yet?
Is my beard too long?

Do any of you ever stop and think about what might be happening within our bodies, like behind the layers of self obsessive nature? As we all should know, blood pumps through each and every part of our body every second, what if there was a camera that could capture all the blood pumps, vein bouncing visuals?

Researchers at MIT are about to share a tech (as open source) involving rapid video capturing/editing which will show the details our naked eyes cannot see right now: (i.e) when and how blood pumps through our faces, when and how a vein pumps through the body.

Very snazzy stuff.
Check out the video for the nitty gritty and an odd visual experience.

#MIT saving us from… #Needles (#injections)

[ScienceTalk]

http://web.mit.edu/newsoffice/images/jet-injector.jpg

Has anyone ever been afraid of needles? I was, and truth be told, still am. And realistically, I doubt if any of you were never afraid of getting multiple injections. Whether you were a kid or in your adulthood, the concept of getting a syringe punching through your skin always brings a burst of fear, if not a burst then at least an uncomfortable feeling attached with hospitals and painful medications slowly diverts your mind away from the real point behind injections.

Well, never fear fellow scaredy cats: MIT researchers are here!

They are in the process of creating a needle-free injection!
No needle = no pain.

Here’s the nitty gritty:
The concept is known as jet injection, with a certain property called  “Lorentz-force” actuator. MIT professor Ian Hunter and his team have developed this property involving magnets and electrocution that pivot the needle (the size of a mosquito’s proboscis) at the speed of sound in air. Since the velocity and intensity of the needle is clearly impossible to react with, there really won’t be any pain experienced by the human brain (i.e our minds are too damn slow to process the procedure).

Best part is that the “velocity and intensity” won’t be executed at the same rate on all patients. For instance, a baby’s skin is much more sensitive than adults, so in that scenario a “slower profiled” property will be executed, which basically means the injection will run at a slower rate.

Can’t wait for this revolution to become the next norm, I’m tired of getting scared by needles, as if a hospital visit isn’t frightening enough.

Watch the video for a demonstration!

Few cool things from the video:
- this process will allow doctors to apply injections directly into the eyes and ears (potentially replacing surgeries)
- this process will allow doctors to use powders to be injected into or bodies target than just liquid substances
- this process will allow doctors to play around with the force of liquid inside the body, the video explains it better

What’s up with 3D printing?

[GadgetTalk]

image

source: http://www.cheers4all.com/wp-content/uploads/2011/09/3d-printer.jpg

The concept of 3D printing sounds exciting, but exactly what is the idea behind 3D printing?

First, a beloved WikiReminder:

3D printing or additive manufacturing[1] is a process of making three dimensional solid objects from a digital file. 3D printing is achieved using additive processes, where an object is created by laying down successive layers of material.[2] 3D printing is considered distinct from traditional machining techniques (subtractive processes) which mostly rely on the removal of material by drilling, cutting etc.
(from wikipedia.com)

The above is a generic reminder about how 3D printing is performed in the world of design and architecture. The industry uses the standard AutoCAD related software to perform such tasks. The emerging trend in 3D printing is actually converting the complicated method of industrial printing into physical printing.

In simple terms: let’s say you find an object online. You’d give anything in the world to make a design out of it. Instead of contacting your local architecture folks or attending an art class to learn how to build a precise shape, manufacturers are now making 3D printers to meet those demands, buy a local printer and let the printer do the precise 3D print.

Well, its an amazing thought of just loading an image and printing it in 3D, but realistically there are a few things to keep in mind.

- you can’t print anything in its pure color
- you can’t print specific (or all) shapes
- there are detailed requirements that an object has to meet
- the “ink” is a complicated concept itself. There are 2 ways to print in 3D: either have a printing needle that has a block of physical object to hammer on, which itself has to know the exact limitation and size of the object. Or use a toxic ink/powder that melts and molds into a 3D shape after its “cooling off” process.

The prices range anywhere from $500 upwards to about $5000. These generous printers meet very specific needs though. Its almost a God sent for those who might be struggling to exist in the art & fashion industry, but after seeing demo videos I’m almost certain that these things will become prominent in the industry.

Enjoy the 4minute video as the printer outputs an actual working wrench.

The connection of #laughter: associated with #learning.

[ScienceTalk]

Source: http://images.mylot.com/userImages/images/postphotos/2284801.jpg

We laugh all the time. At jokes, movies, but do you ever sit down and wonder why a statement makes you laugh. The idea is to think about your body’s behavior, not the joke itself.

According to vsauce’s research, the idea of laughter is related to accepting new knowledge in our brains and is only connected to, yes: learning. When people make silly jokes, people laugh at them mainly because theyve never learned those facts in that particular fashion before. Its new, its fresh, so its a delightful experience especially if it curtails to your cup of interest. Think of your school, a political gathering, a concert, a sport game, an entertainment scene. Everyone gathers around to watch, experience, extract new information – this is how we learn. We express emotions and laughter is one of them.

Now there are a lot of people who laugh at silly jokes, like racism, sexism, etc. Do you know why they are so famous and popular? Because they are ideas. Ideas that people dont want in their heads but they like it because they are new. They bring a fresh excitement to our established thoughts, but I knew that these jokes don’t logically make sense, because indirectly they are feeding knowledge that should be barred away from us. The idea of unequal races, sex, and people is what stems from such jokes. Because these are bad ideas, but related to jokes which make us laugh: we are learning these things, accepted by the brain. The fact is when people learn something they dont reflect on it, since this type of learning is related to laughter and is taken lightly, its actually given the green signal in the brains to roam around with freedom. Only afterwards its our own responsibility to steer the idea to our ways of thinking and actions that should be socially proper.

So the next time you hear a joke, try to think about it first before laughing, and after you laugh think about it again and tell yourself what you learned but what you should and should not.

#Car-Plane: Demo inside a TerraFugia Transition Aircraft

Did you know: someone has developed a car+airplane that can use our local road infrastructure to fly in the sky and drive on the road at the very same time?! It’s known as the TerraFugia Transition Aircraft, which basically converts on-road vehicles into on/off-air vehicles!

If you didn’t know, here’s your chance to look inside the ‘beloved cockpit’.

Mechanically, its a small 2-seat airplane that can squeeze its wings by its sides so that it converts itself into an automobile. Think of a bird and how it can flap its wins if it wants to fly, but jumble them up when on the ground. All technological advances are a wanabe copies of things in Nature <3.

The gadgets and features inside the car look pretty cool. Check it out below.

#IBM – Oxygen #Battery? YES – “#LithiumAir”

[TechTalk]

Source: http://www.blogcdn.com/www.engadget.com/media/2012/04/breather.jpg

A car-battery that uses Air/Oxygen reacting with ions and electrons — producing electric charge lasting upto 500 miles (805KM) — too good to be true? Almost.

IBM’s lastest development in this area is proving to be a success. Labelled as “Lithium Air”, the battery is designed to “borrow” incoming air (consisting oxygen) particles which then react with the battery’s inner parts: namely lithium ions and electrons — generating electricity! The coolest thing about all this process is the charging part. When the battery is being ‘charged’ – the “borrowed” oxygen is given back to the environment and a reverse reaction takes place inside the batteries.

How cool is that!

I’m glad there are still tech companies out there who focus on better things than suing others for patent disputes and going mainstream. This kind of research builds our future, not the industry in general for revenue. Props to IBM, who are planning to expand this research to an extent where they can mass produce and have it available by the year 2030. Don’t forget to check out the video below.

Make your #devices #waterproof

[TechTalk]

imageNow this is evolution.

We all know that water/liquid and technology don’t mix well together. There is a discharge of static or an instant malfunction if liquid is exposed to any party of the circuitry.

Lo and behold, the liquid protecting layer from Daikin Industries.

Whats so good about it?
- the used chemicals are low toxins (Fluoroplymer Film)
- protect mesh surfaces like speaker holes as well as headphone jacks
- prevent static malfunction as water simply floats on the circuitry
- developed in Asia and should be out by DECEMBER 2012!

Since its from Asia expect prices to be relatively cheap. Below is a demonstration video of how it works and flawlessly becomes immune to liquid!

#Natural-Ear-Tech – how ears detect single ‘sound wave’ in a crowd

[ScienceTalk]

Source: http://images.emedicinehealth.com/images/eMedicineHealth/illustrations/ear_cutaway.jpg

Let’s say its your first day at your NEW school and it’s lunch time. You’re sitting alone in the cafeteria at a lunch table and have no friends and feel lonely, you notice a lot of people through your eyes BUT what you also notice is the amount of NOISE the big crowd is generating. After minutes of boredom and loneliness, you suddenly hear a screeching voice/sound calling your name, and you finally start feeling welcome. This is where I want you to actually THINK about the magic you missed out on.

Out of all those noises that were generated from the crowd, could you have wondered how that single sound was detected? Compare that environment with a place where there’s no noise and even a single pin drop would make your ear wiggle, do you know how your ear differentiates the ‘silence’ from a ‘sound’ or ‘one sound’ from an ‘ocean of sounds’?

You can say:

  • Yeah someone called your name and you detected it easily, but think of your name as a sound-wave rather than your actual name.
  • You can even say that the call of your name had a higher pitch than others. Even at this point I’d like you to stop and just think how your ear differentiates the length, pitch, volume, tempo of a sound wave.
  • You can give credit to your magical ear drums for that as well, and pretend to know-it-all.

But here’s where your brain’s tempo might explode: did you know that even scientists – to this very day with advanced science and technology at their disposal – haven’t figured out how an ear detects/differentiates a louder voice in an already ‘filled/noisy’ environment.

The source article might have figured something out, but not entirely. They mapped how the brain also helps divert the ear drums attention to sound waves, concluding: our brain helps us perform selective hearing. How is it done? … hasn’t been mapped out yet but hey, its discovered! So I’d say the golden egg has been found now they have to research more to look inside the egg.

If you deeply think about it you should come to a conclusion that there’s no such thing as “no-noise” or “mute” – everything from mute to sounds is an environment. Your ears adopt to your environment thanks to your brain. They can actually ‘shove away’ whatever sound your brain doesnt want to hear.

Fascinating stuff. Nature is the true technology of this world.

As an added bonus, watch this amazing video from YouTube about how sound-waves enter and are processed in humans.

#Clouds and their weight

[ScienceTalk]

Picture Source: http://www.clker.com/cliparts/d/e/a/b/12741125501689130202cloud.png

Some general knowledge for ya’ll.

We always look at the bright blue sky, beautiful clouds rolling about on a daily basis. Im sure most of you probably have thought of flying through these skies (well I have, and still do sometimes!!) – especially the notion of “passing through the clouds”.

Let’s stop the great imagination for a bit.

Have you ever thought how much do clouds ACTUALLY weigh? What about the big dark grey clouds, or how about hurricanes in general? Thanks to vsauce on YouTube (for sharing this video in their LeanBack playlist), and the video below from NPR channel – I’ve been exposed to this interesting fact of life.

I’m having second thoughts about those fluffy clouds and the ‘image’ that we have in our minds about them being all cushy and mushy and lightweight.

Check this out.
