Did You Know -01/11/2016

  1. The level of melanin in your iris controls eye colour. Brown eyes contain more melanin (a dark pigment in the iris), while blue eyes have less. This enables blue collagen to show through. It is interesting enough to note that if you have blue eyes, you share a common ancestor with every other blue-eyed individual on earth. The first ever blue-eyed person lived sometime between 6,000 and 10,000 years ago. Before him, everybody had brown eyes.

These are just some of the amazing facts there are about the eyes which should give you enough reason to be thankful for them.

2. In 1977 a 37 year old man named Jerry Ehman was a voluntary researcher for Ohio State University’s now defunct Big Ear radio observatory. It was here that a giant telescope was scanning the skies on August 15. In those days, any information was processed through an IBM 1130 mainframe computer, printed onto some perforated paper and then examined by hand. It was by doing this that Ehman spotted something extraordinary – a vertical column with the alphanumerical sequence: ‘6EQUJ5’. Ehman grabbed a red pen and circled the sequence. In the margin he simply wrote ‘Wow!’.

More than three decades later, the Wow Signal is still the first and best potential evidence of communication with extra-terrestrials and it also remains one of the biggest mysteries in science. Over the years, Ehman and his colleagues have worked to rule out potential candidates of what the signal could’ve been sent from – such as satellites, aircrafts or ground-based transmitters on Earth. Although this is the case, it still hasn’t been proved the signal came from ‘aliens’.

The Wow Signal is one big open question.

3. A dog’s love towards his family is unconditional, and a classic example of this is the story of Hachiko, an Akita dog who was born in 1923 in Japan. He was adopted by an agricultural professor who took him home and took on the role as his new owner. Both of them formed a very special bond.

During their time together, the professor would take a train ride home each working day and be greeted by Hachiko at the train station. Hachiko would sit and wait for the professor at the end of each working day, without fail.

one day the professor suffered from a cerebral hemorrhage (brain bleed), and passed away, never to return to the train station again where his beloved companion was waiting.

For the next nine years, Hachiko attracted the attention of many people far and wide as each day, without fail, he would visit the train station as normal and wait for his owner.

Hachiko passed away in 1935, aged 11 years

4. Clinomania, or Dysania as it is more commonly known, causes sufferers to find it extremely difficult to get out of bed in the morning.

Clinomania, or Dysania as it is more commonly known, causes sufferers to find it extremely difficult to get out of bed in the morning.

Classified as an anxiety disorder Dysania sufferers wake readily enough, however they find the task of rising from bed extremely difficult. The condition is commonly referenced when a diagnosis of Chronic Fatigue Syndrome

5. Mephobia – Fear of becoming so awesome that the human race can’t handle it and everybody dies. 

 The phobia does indeed exist and there have been a few reported cases of people having it – though many more claim to have it!

Seal A Gunshot Wound In 15 Seconds

incredible-yet-simple invention can seal a gunshot wound in 15 seconds 1

While the U.S. Defense Department is taking bold steps to embrace the latest technology in nearly every operational specialty, it might be the simplicity of a kitchen sponge that saves hundreds of lives every year.

The new battlefield gadget is called X-STAT, and it uses a novel twist on simple science, offering a different way to treat deep gun shot wounds that have plagued military medics for years.

The sponges work fast: In just 15 seconds, they expand to fill the entire wound cavity, creating enough pressure to stop heavy bleeding, reports Popular Science. Keeping the technology simple is hugely important in the chaotic, pre-hospital environment. RevMedx designed the XSTAT to literally be plug-and-play.

The dime-sized expanding sponges – which are made from standard medical-grade sponges and covered with a hemostatic agent – are injected into the wound with the plastic tube and immediately expand to stop the bleeding. And because the sponges cling to moist surfaces, they can’t be pushed back out of the body by gushing blood.

RevMedx claims uncontrolled bleeding is the leading cause of death on the battlefield and the second leading cause of death in civilian trauma. According to a report published by the National Center for Biotechnology Information, the highest percentage of survivable battlefield deaths from 2001-2009 came from major trauma hemorrhage.

RevMedx, founded in 2009, focused their research on solving the problem of “non-compressible hemorrhage,” and believes their modified syringe that injects specially coated sponges into wounds will be the solution:

“A significant number of wounds occur to regions of the torso where compression cannot be applied, such as the pelvis or shoulder … By working closely with the US Army Medical Research and Materiel Command and US Special Operations Command, we succeeded in developing a novel hemostatic dressing capable of stopping high-flow arterial bleeding within seconds without external compression.”
RevMedx recently petitioned the FDA for approval of their invention, Popular Science reports. The company claims XSTAT could boost survival rates and spare injured soldiers from additional pain.

“The core technology behind the XSTAT dressing is mini-sponges that expand upon contact with blood — resulting in a nearly immediate hemostatic effect without manual compression,” the RevMedx site states. “We are incorporating this self-expanding sponge technology into a portfolio of hemostatic dressings to treat a wide range of wound types.”

The DoD Hemorrhage and Resuscitation Research and Development Program portfolio manager said the XSTAT provides the military with a totally new way to save lives, according to the Army. “It is a capability that has never existed before, and can be used in the field setting by medics, possibly even with buddy aid,” Dr. Anthony Pusateri said.
