Our Bodies’ Best Buddies Elisabeth M Bik, Stanford University Note: this article was written for the September 2014 issue of the San Francisco Medical Society magazine.

This post covers a brief history of the Universe from the Big Bang until the the present day. This, as I am sure you’ll agree, is a pretty big topic so I can only give a outline of some of the key events and when we believed they happened. This post is the second in my series about cosmology, which is the study of the origin and evolution of the Universe as a whole. To view my previous post click here.
Before I start talking about the history of the Universe I first need to give a brief overview of atoms, which are the building blocks of all matter – with a notable exception which I will explain below.
What are atoms ?
An atom consists of a nucleus, which has a positive electric charge, surrounded by negatively charged electrons. Atoms are very small, typically around 0.0001 microns in diameter (a micron is a…
What is a black hole? A black hole is an object with so much mass that its gravitational pull is humongous. The speed needed to escape the pull of the gravity (escape speed) is faster than the speed of light, so light will get sucked in and trapped forever. As nothing is faster than the […]

The immune system is a complex and remarkable aspect of our bodies. To protect our body from harm, this system will do all it can to destroy the invading pathogen. Sometimes this can go wrong leading to an allergic reaction, and even anaphylaxis – the worst case scenario. The videos below superbly explains how our […]
It’s clear we do need dragons, even if only for the sole reason that it’d be absolutely awesome!.. Reading this blog post made me think – how hard would it be to (bio)engineer a dragon? I’ve put some thought into it and a pinch of my biology and genetics knowledge, and figured that if I…
today I will write about pareidolia as commonly seen phenomena. People often see familiar objects in completely random things, like rocks.
Clearly there is face in the upper middle part of the picture on the left. There is definitely sign of both eyes, of nose and mouth, thats more than one needs to
recognise face in something, consider the following one on the right. Do you see the black thick circle filled with yellow color, two ellipses and curved line extended in the ends? Yeah me too.
The point is that humans are great in recognizing (most often faces) in things that are actually not them. The first picture is photo of region Cydonia which is a area on Mars. It was taken in 1976 by Viking 1 and of course people thought that it was proof for extraterrestrial life! Well if you take enough photos of Mars there…
