Pakistani boy wins second place in NASA competiton

Monday, August 24, 2015 View Comments

Shah Mir Aizaz, a Pakistani student from Grade 10 has won the second position in 2015 NASA Ames Space Settlement Design Contest.

Every year, individuals, small teams of two to five, and large teams of six or more are invited from all over the world to submit space settlement designs to NASA Ames for judgement. This year there were 994 submissions from 3,007 students. Entries came from 21 nations worldwide and 14 different states from USA.
Shah Mir Aizaz registered in his individual capacity and won 2nd place for his report titled “Beyond Infinity – Eros Outer Atmosphere Settlement.”. His work was judged by aerospace professionals, and was thoroughly examined for its ideas in making a space city work. He had to figure out answers for issues such as air supply, agriculture, infrastructure and more in an environment that theoretically does not support human life.

Shah Mir, we are really proud of you. May you bring further glories to Pakistan, Ameen.

Femtosecond Lasers Create 3D Images in Mid Air Which You Can Touch

Friday, July 3, 2015 View Comments
A Fairy in Mid Air

Femtosecond lasers are the latest cutting edge technology in ophthalmology and have led to the development of many new techniques and refinement of old techniques in refractive surgery. 

Now scientists from the University of Tsukuba, Utsunomiya University, Nagoya Institute of Technology, and the University of Tokyo, have used femtosecond lasers to produce 3D images in mid air by ionization, which can be touched and interacted. The most important feature of the system is that power of laser is reduced to such an extent that it is not harmful to the skin. Plus interacting with the image generates small shockwaves under the skin, so one can have haptic feedback as well.

Watch the Video at these links
to see the awesome magic in action.

Tips for surviving the current heatwave in Pakistan

Tuesday, June 23, 2015 View Comments
I am breaking my silence of more than a year by the sad news that, Pakistan's current heatwave has claimed around 800 lives. The government is being held responsible for it because of their lack to provide uninterrupted water and electricity supply.

How the body responds to extreme heat

The body's normal core temperature is 37-38C.
If it heats up to 39-40C, the brain tells the muscles to slow down and fatigue sets in. At 40-41C heat exhaustion is likely - and above 41C the body starts to shut down.
Chemical processes start to be affected, the cells inside the body deteriorate and there is a risk of multiple organ failure.
The body cannot even sweat at this point because blood flow to the skin stops, making it feel cold and clammy.
Heatstroke - which can occur at any temperature over 40C - requires professional medical help and if not treated immediately, chances of survival can be slim.

How to stay safe against extreme heat

wearing damp clothes which will help lower the body's temperature.
sticking one's hands in cold water.
placing fans next to windows as this will draw air from outside, which should be cooler
wearing looser clothes.
having a lukewarm shower rather than a cold one.
fanning the face rather than other parts of the body.

How to apply, remove and care for contact lenses

Thursday, February 13, 2014 View Comments

Contact lenses have become fairly common now, especially the cosmetic ones. But still people, even the highly educated ones, don't know how to care for them.
This video by Bausch & Lomb gives an excellent demonstration on how to apply, remove and care for them. Although I personally don't like to promote any specific brand but the video prepared by them is impressive and should be shared.

What an ophthalmologist learnt at a dentist's clinic

Monday, January 27, 2014 View Comments

Few days ago, I had root canal  treatment of my molar tooth. It took around 3 sessions for the procedure to complete, of which second session was the most painful. As I went to the dentist's clinic on alternate days from a patient's perspective, few important things tinkered my mind, which I would like to share.

- The environment of the clinic, doctor himself, clinic assistant etc. should be clean and tidy.
- Be straight forward about the state of the disease and don't give false hopes.
- Be fair in telling what you have encountered during the procedure and the results should be properly explained.
- The words should be very careful chosen while talking to the patient.
- Anesthesia should be effective, otherwise the patient will be surely angry at you.
- Don't hurry to finish the case while you get to know that the next patient is waiting.

Three American scientists, Randy W. Schekman, Thomas C. Südhof and James E. Rothman, have been awarded Nobel prize for their breakthrough research work on the transport of enzymes, hormones and neurotransmitters in form of vesicles within cells. 

The three laureates discovered how these vesicles get to the right parts of the cell at the right times.

Their work can help solve the problem of diabetes ( in which insulin doesn't reach other cells at the right time ), various neurological diseases like schizophrenia, autism and many others.

The three will share 1.2 million dollar of prize money.
