An Arbitrary Anniversary of Science

We always seem to be looking forward in science. The fact that everyone is excited about the next robot venture on mars or breakthrough in medicine is what drives research and innovation in the first place. However, I think it a pleasant idea to look back at some of the memorable moments in science that have shaped our world and brought us here to these exact circumstances. So, here is a little retrospective of science on January 28th, going back as long as four centuries ago.

And what’s so special about January 28th, you ask? Nothing! That’s what makes it fun to look back. So, enjoy!

  • 1613:Galileo records observing a “star” which is actually (most likely) the first viewing of planet Neptune.

  • 1807: Pall Mall, London, England, is the first street in any city to be lit by gaslight, courtesy of entrepreneur Frederick Albert Windsor.
  • 1903: Birthdate of Kathleen Yardley Lonsdale, a crystallographer who proved the flatness of the benzene ring.
  • 1922: Birthdate of Robert W. Holley, joint recipient of the 1968 Nobel Prize in Medicine for describing the structure of alanine tRNA.
  • 1958: Buchanan, New York sees construction begin of the first private thorium-uranium atomic reactor to supply power.
  • 1960: the U.S. Navy bounces the first wire photograph transmitted by radio waves off of the moon at a 400-MHz frequency.
  • 1986:The tragic Challenger space shuttle explosion kills seven astronauts after a mere 73 seconds after liftoff.

  • 1999: Element 114, Flerovium, is reported by Russian scientists at Dubna (Joint Institute for Nuclear Research).
With these events and discoveries, we can celebrate January 28th as an arbitrary anniversary of science.

DARPA Foam – A Foam That Can Save Lives!

“OH GOD! THERE SO MUCH BLOOD! HE’S GOING TO DIE!”

Internal bleeding. This type of injury is one of the most troublesome injuries due to a limited time frame a person has before they are treated.  However, thanks to advancement in medical science, the Defence Advanced Research Project Agency (DARPA) has launched its Wound Stasis System to develop the, “DARPA foam“.

The “DARPA foam” is a special injectable polymer foam that slows internal bleeding in the abdominal area of the body by having the foam mould around the internal organs to slow the bleeding long enough to have the patient seek professional medical treatment.

The foam works by first injecting it in the abdominal cavity in its two liquid phases. As the liquids mix, it will form two chemical reactions. The first reaction will make the foam expand thirty times its original volume and surround nearby internal organs while conforming to the surfaces of injured tissues. The second reaction will then harden the foam so that blood flow will be restricted, and will slow down blood loss. After the foam has been properly formed, the next step would be in removing it, which based on previous tests, is remarkably easy. Surgeons were able to remove the hard foam from their patients in less than a minute.

This new life saving technology that can reduce blood loss by six-fold and increase the life expectancy of a patient to three hours post-injury, should be given full support from everyone within the medical field. Even though this technology was originally developed for military use, hopefully after more tests and more positive results, this technology can one day be found in every ambulances in the world.

Laughter is the Best Medicine?

Now I know, we’ve all heard time and time again “Laughter is the best medicine”, but where did this saying even come from? Is there any scientific backing to this?

Well, turns out there is.

Dr. Lee Berk, an associate professor  at the School of Allied Health Professions at Loma Linda University, has been studying the effects of laughing, or humor, on the human body for years. In one of his experiments in the 1990’s, it was found that after watching something comedic, or funny, ones immune system created more t-cells, which are essential for fighting off infected cells in the body. Watching something funny and laughing ‘mirthfully’, as he describes it, helps to lower ones blood pressure, and improves the function of blood vessels.

It is also known that laughter releases endorphins in the body, which are neurotransmitters, responsible for the the ‘feel good’ chemicals of the body. Laughing also helps to relax muscles, and decrease pain.

Above is a video of an interview with Dr. Berk himself explaining his work, and some of his findings.

Researchers estimate that laughing 100 times is near the equivalent of using a rowing machine for 10 minutes, or an exercise bike for 15 minutes! Did you ever wonder why after a good long laugh you have trouble breathing, or your abdominal area hurts? Its because laughing is near the equivalent of an aerobic workout! Just make sure your laugh is a full and hearty one, fake and/or light laughter is not nearly as effective.

So next time you’re feeling under the weather, don’t mope about it. Pop in a funny movie and let your laughter help heal you!
