This is totally not my field-- medicine-- but totally up my alley-- electronic gaming.  So here goes.  Doctors prescribed playing Nintendo games to cure a boy's blindness in one eye. …

"It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts..." Sherlock Holmes

The following is based on my idea that there are two main problems related to halting problem: That you can not check if program does not halt. You can always check if it does. That the finite state…

Theories of physics rest on fundamental assumptions and those assumptions are based on how the real world works, and often produce amazingly precise predictions.  The most comprehensive theory…

How do plants perceive environmental stress ? Biotic and abiotic stress induces plant response and before" dying" different levels of resistance is shown and finally plants are overcome with stress…

It's no secret we have done things our own way here - no marketing, no corporate hierarchy, no political or cultural litmus test and no requirement that you already be popular before you can join.…

An international team of scientists say a new  technique could turn pulsars into superbly accurate time-keepers. A pulsar is the spinning, collapsed core of a massive star that ended in a…

The beauty and utility of crystalline materials has seen in almost every application today.  From silicon microprocessor and photovoltaic technologies, to dielectrics, laser applications, optics…

We have studied constraints to programs, but we can use constraints to programmers instead. Let's assume the following constraint: Programmer must always figure out, for his specific algorithm, how…

Let's assume that we do not have a DoesHalt(program) function, but DoesHalt() function inside runtime of program, which is able to signal true or false. It is also able to hang. At first, the case…

Introduction The use of non-human animal models has allowed the fast progression of scientific discovery over the last several centuries. These experiments have lead to great discoveries that have…

Physics and Technology of CCD A charge-coupled device (CCD) is a device for the movement of electrical charge from one capacitor to another one developed by W. Boyle and G. Smith in Bell Laboratories…

Today is the 2000th day of blogging for me. And this is my 2003rd post! It all started in December 2004, when I first learned about the existence of a thing called "blog". I had been contacted by…

One balmy July afternoon, when the fresh-faced optimism from having completed my PhD had seriously begun to wear off, I went to lunch with a famous scientist.  This jovial, moustached…

Can elicitors like Chitosan elicite the same response as the stress signals in plants. How one can relate both the phenomenon. Do stress induced proteins also have a role in signal transduction

Sodium chloride or for that matter largely sodium acts as signal to activate various metabolic pathways in plants including response to stress. Human brain also has some kind of Sodium balance i.e.…

A new study published in the Proceedings of The National Academy of Sciences has compared the qualifications and publication histories of climate change skeptics to those of Anthropogenic global…

Arctic Tipping Points - #7: Can The Arctic Recover? In Arctic Tipping Points - #6: Are We There Yet? I attempted to show that there are multiple feedback mechanisms which are capable of causing a…

When light is used to transmit information,  modulated light pulses travel along optical fibers, which can become weaker due to optical attenuation in the fiber and so are refreshed in signal…

A neutrino has a mass, physics says, but it is elusive to figure out and extremely hard to measure – a neutrino is capable of passing through a light year (about six trillion miles) of lead without…
