Unfortunate, but inevitable
by Neutron on Jan.20, 2011, under Musings, Personal, Research, Running
I have been training quite hard the past few months, on my quest to push myself beyond the limitations I had for myself. Believe me, I don’t set my limits that easily and the past 6 races have pushed them recursively, as I thought would the next two. Unfortunately, my pickup soccer routine has gotten in the way of reaching there.
Last Wednesday, while playing a friendly, I fucked up my knee. Needless to say, I am very disappointed. Unfortunate, true. Inevitable, probably yes. Considering the amount of things I was trying to do simultaneously, I am happy it took this long to bring me down.
Now, my knee is swollen up the size of a football, I cant run my Austin marathon and can’t play soccer for at least 2 more months. Adding this on top of losing all my past data (6 years worth of research), it just makes this new year as one to be remembered. OR one to be despised… Let’s just hope that the rest of the year will make up for all this bad spin on the year…
karma
by Neutron on Oct.11, 2009, under Poetry, Research, Running
In pain, and satisfied like a well-fed child,
Conquering 22 miles in agony, amongst lost strides,
In training, the test still weeks away,
Work to be finished, and more miles ahead,
Another journey with high hopes, treads.
A good week, I presumed.
Bugs fixed, a near marathon complete,
but a little thought reveals a treat,
Of more work remaining,
Completion never in the vicinity.
Cause and effect do change,
Perspectives, opinions and ambition;
Work unfinished, drives and stalls elation.
Does all this work still make the difference,
Between life and beyond ?
I understand, action begets action, the inevitable,
The more you try, the deeper you sink;
Like caught in a quick sand, terrible
the fright, the action necessary is to avoid action.
When will I learn ?
A.Q. Khan on Pakistan’s Nuclear Program
by Neutron on Sep.22, 2009, under Defense, News, Nuclear, People, Research
I just came across a very interesting and revealing interview with A.Q. Khan who was on house arrest till early February this year for his involvement in organizing one of history’s worst nuclear scandals. The transcript of the interview is available over here and is worth the time in gaining insight on the dynamics, timelines and even the budget involved for Pakistan’s nuclear program.
[Malik] When did you come to believe that now you had the weapons-grade uranium?
[Khan] In Kahuta, we achieved 60 percent result in our enrichment program; it was a
very difficult task though. We faced a lot of challenges in the ensuing stages but
successfully managed to overcome them, and we had achieved 90 percent result in the
//enrichment// program by the early 1983.[Malik] So when was the bomb ready?
[Khan] It was ready by 1984. I wrote a letter to Gen Zia on 10 December 1984, telling
him that the weapon was ready and that we could detonate it on a notice of one week.[Malik] Why did you not decide to test that device as soon as it was ready?
[Khan] We were allying with the United States in the Afghan war. The aid was coming.
We asked Gen Zia and his team to go ahead with the test, but they said they could not
conduct the test as it would have serious repercussions. They argued that, since the
United States had to overlook our nuclear program due to our support in the Afghan
war, it was an opportunity for us to further develop the program. They said the tests
could be conducted any time later.
Even though there is no value in pointing fingers at anybody, it is horrifying that repercussions of the US involvement in the Afghan region is still coming back to bite everyone, US included, in diabolical ways. Read the rest of the transcript to get a better perspective on things.

Wiggle that big toe.
by Neutron on Sep.03, 2009, under Musings, Personal, Research
Past few years, I’ve changed my outlook towards life or rather refined would be a better way to put it and sitting alone, contemplating and meditating on how far I’ve come, still puzzles me. I want to say so many things, put forth ideas that could be useful to others but part of me does not feel like solidifying it in words. Unconsciously, the writer’s coma that I’ve been trying to wake up from has also been affecting my work and the vigor, passion seems to have fizzled a little, it seems. Now that I understand quite well what I do, it does not hold my interest as it once did. Bigger challenges await in future for sure but task unfinished grows from monotony.
Nevertheless, I’m trying to wiggle my big toe, the crud caught up in my mind, blocking my thought flow, to get going a new lease on life and realize the original priorities, to finish what I started. Abstract but clear, visible is a new beginning and an upcoming end of an old chapter.
I hope in another 4 months to finish the work and get my head around my plan for the future… Or maybe just a month of good sleep might clear my head enough to stop all this rambling.
Pepsi’s new logo: A mindblowing effort …
by Neutron on Feb.12, 2009, under Fun, Humor, Research, Trivia
True. If you are buzzed on beer or stoned on weed, and someone pays you to work on a new logo, this would be the exact result of such an effort.
It not only is hilarious, but brings about a sad truth as to why anyone would get paid millions of dollars for such an advertising when the economy is tanking while there are genuinely talented folks getting laid off and struggling to hold on to their jobs.
Well, enough of me ranting. If you got some time to kill, definitely check out the following link and do not forget to read the full document at the end. Enjoy creativity like you have never witnessed before.

Atomic John
by Neutron on Jan.26, 2009, under Gadgets, History, Nuclear, People, Research
There has been quite a furore about an unknown truck driver delivering a thorough account of the first 2 nuclear bombs ever built on the face of the earth. Intrigued and excited, I searched google to read more about him and stumbled on this gem of an interview/article that brought him to light.
Read David Samuels’s account about the truck driver, John Coster-Mullen, who conducted more than a decade of research to successfully build the first accurate replica of Little-Boy, the master-blaster that annihilated Hiroshima, ending WWII. The article itself is quite interesting and leaves you wanting for more. Here’s an excerpt:
I recently wrote to Coster-Mullen and suggested that we take a trip across the country to visit his Little Boy replica, which is currently housed at Wendover, a decommissioned Air Force base in Utah. After some negotiation, we agreed to ride together on his late-night delivery route between Waukesha and Chicago. We would then drive to Wendover. Along the way, he would explain the inner workings of the first atomic bombs, and I would learn how he got it right and the experts got it wrong.
I can’t wait to get my hands on the his book “Atom Bombs: The Top Secret Inside Story of Little Boy and Fat Man”.
Quantum Information Teleported Between Distant Atoms
by Neutron on Jan.25, 2009, under Physics, Research
For the past few years, I have been following the buzz on quantum computing. Even if I only barely understand the theory behind physics involved, there is still something mysterious about quantum mechanics that keeps bringing me back. Anyway, I diverge here.
Recent breakthrough in quantum computing occurred when scientists were able to successfully teleport information between two distant atoms. Furthermore, there are huge possibilities in the field of quantum cryptography if the efficiency of the quantum entanglement is a little more feasible.
Refer to the original article below for more information.

Why we kiss
by Neutron on Feb.05, 2008, under News, Research, Trivia
I recently read an article on the Scientific American on “Why we kiss” and it is interestingly controversial. Fortunately, it does address some of the common questions I’ve heard before and hence, this might be interesting enough to read on a sunday afternoon.
One of the first questions that is answered is “Why do we do it ?”
Excerpt from the article:
Whatever else is going on when we kiss, our evolutionary history is embedded within this tender, tempestuous act. In the 1960s British zoologist and author Desmond Morris first proposed that kissing might have evolved from the practice in which primate mothers chewed food for their young and then fed them mouth-to-mouth, lips puckered. Chimpanzees feed in this manner, so our hominid ancestors probably did, too. Pressing outturned lips against lips may have then later developed as a way to comfort hungry children when food was scarce and, in time, to express love and affection in general. The human species might eventually have taken these proto-parental kisses down other roads until we came up with the more passionate varieties we have today.
Well, that makes a lot of sense. I believe that a lot of the actions we perform are deeply influenced by what animals did out of survival which later became acts of luxuries and a part of social behavior itself. So I’ll leave this at that.
Another interesting quote from he article is as follows:
“Kissing,†said evolutionary psychologist Gordon G. Gallup of the University at Albany, State University of New York, “involves a very complicated exchange of information—olfactory information, tactile information and postural types of adjustments that may tap into underlying evolved and unconscious mechanisms that enable people to make determinations … about the degree to which they are genetically incompatible.†Kissing may even reveal the extent to which a partner is willing to commit to raising children, a central issue in long-term relationships and crucial to the survival of our species.
There are few other interesting tidbits of information about how human sensory organs behave and the reactions of the brain during a kiss. Useless, but fascinating nonetheless.
Well anyway, at the end of the day, it really does not matter what these studies come up with for results. Since perceptions are averaged over thousands of people and there is a high probability that me or you do not perceive like any of them or the person you kiss, all you can do is read it and move on
The new Russian bomb
by Neutron on Sep.13, 2007, under Defense, News, Nuclear, Research
I am sure you’ve heard the news already and seen the video of the explosion a million times. That is unless you are living under a rock. The new bomb is supposed to be completely free of nuclear materials but still delivers the “boom” that would be expected of a nuclear device. Quite interesting and a little scary considering that Putin has been sacking and shuffling his cabinet recently to fit the profile he wants. Is this an attempt by Putin to bring Russia back into a state of global power ? Time will tell.
Anyway, without diverging further, let me give you an excerpt from an article on the new Russian test. From CNN
The Russian military has successfully tested what it described as the world’s most powerful non-nuclear air-delivered bomb, Russia’s state television reported Tuesday.
The bomb’s detonation is shown in this image taken from videotape.
It was the latest show of Russia’s military muscle amid chilly relations with the United States.
Channel One television said the new weapon, nicknamed the “dad of all bombs” is four times more powerful than the U.S. “mother of all bombs.”
“The tests have shown that the new air-delivered ordnance is comparable to a nuclear weapon in its efficiency and capability,” said Col.-Gen. Alexander Rukshin, a deputy chief of the Russian military’s General Staff, said in televised remarks. Video Watch Russian bomb test »
Unlike a nuclear weapon, the bomb doesn’t hurt the environment, he added.
<sarcasm>YESSS ! It doesn’t hurt the environment ! That should keep the global warming fanatics quiet. You showed them Russia. Way to go.</sarcasm>
Retards.
Btw, also found a nice video of the test, an official release from the Russian government. I should say, the mushroom clouds get me all tingly every time I see it on video. Let’s hope I’ll never have to see that in person during my life !!
Take a leap into hyperspace
by Neutron on Jan.07, 2006, under Research, Science
Now, did the title catch your eye ?! It sure did that to me. I went ahead and read the article over at NS and was amazed at what i saw there. The article details about an unknown scientist’s work in Germany about an attempt to make a GUT(Grand Unification Theory) which ended up opening new realms to explore and exploit.
Hyperspace is a concept which will enable a spacecraft to reach Mars in less than 3 hours and a star 11 light years away in only 80 days. Now that, is abstract physics at its best
If you are interested, go ahead and read the article. If not comprehensible, it sure is a nice read that reminds me of ‘Star Trek’.
Ten bogus frights of the past that shocked the world
by Neutron on Dec.24, 2005, under Links, News, Research, Science
Bird flu has overshadowed the year 2005. The abominable virus claimed many bird lives in South East Asia before heading across Europe to Russia and Ukraine. However, the more scientists and officials talk about the deadly threat, the less credible it looks to people. Some people believe there is no such thing as bird flu. They think the whole story stemmed from the fights over the world market between the poultry producers. Others blame the pharmaceutical companies that are keen to spread panic and therefore make us buy more medicines. Which story should we believe in? Does the bird flu really exist? Does it pose a threat to humans? Did other threats of the worldwide proportions materialize?
It did not take long to tackle the problem; doctors found a pathogen and a vector – coronovirus and a palm cat, a viverrine animal normally used for food in China. However, the urgent measures could not stop another myth from spreading far and wide. The myth said that the SARS problem was made up to lower China’s economic growth and disrupt the exceedingly profitable tourist industry in South East Asia.
Academician of the Russian Academy of Sciences Lev Sandakhchiyev:
“Discovering a new more dangerous type of previously unknown coronavirus in the patients was direct evidence of a real threat. The ‘spinning’ of that epidemic stressed the importance of international cooperation. Many people did realize that humankind was destined to face new or recurrent infectious diseases. Therefore, a system of global and domestic monitoring is highly required.”
Spent nuclear fuel
Following a heated debate in 2001, the Russian president signed into law the bill on storage and reutilization of spent nuclear fuel from foreign nuclear power spent nuclear fuelplants. Specialists were unanimous while explaining to their opponents that spent nuclear fuel was not just the waste material from the nuclear industry. According to them, it is a high-tech product that can be used for extracting raw materials and energy. Despite potentially huge profits Russia could make (one ton of spent nuclear fuel costs $1 million; total estimated amount of spent nuclear fuel is 200 thousand tons), environmentalists have been relentless in their opposition to the new law.
Nikolai Shingarev, Director of the Information Center of the Federal Agency on Nuclear Energy:
“No spent nuclear fuel is being brought into Russia despite the law. We will probably sign the first contract under the new legislation for a small consignment of spent nuclear fuel from a research reactor in Uzbekistan. Today Russia is receiving nuclear waste from the nuclear plants built in the Soviet era in Ukraine ($370 thousand per 1 ton) and Bulgaria ($600 thousand per one ton). Reutilization waste materials will be stored in Russia only if the governments OKs the storage and only if fuel had been originally produced in Russia. 75% of revenues will be allocated for environmental programs and the remaining 25% will make part of local budgets.”
10 myths of the past, which never materialized
Steam-driven locomotive: serious scientists were asserting that cows would stop bearing offspring and produce milk at the sight of a locomotive. They also clamed that air would be squeezed out of train carriages at 20 km per hour and passengers will suffocate as a result.
Robot: intelligent machines will shake off dependence and take command of the world; humans would submit to the power of the machines.
Spacecraft: spacecraft were making holes in the atmosphere during the takeoff; the earth’s protective anti-radiation layer of the atmosphere will be eventually destroyed and thus the earth will be exposed to dangerous space particles.
Microwave oven: fried sausages can irradiate in the dark; radiation from food cooked in the oven will pile up in the human body and cause cancer.
Cell phone: radiation emitted by a cell phone receiver can affect the brain by liquefying it. Paradoxically, a cell phone phobia could not stop the massive spread of cellular communications all over the world.
Vaccination: the danger of vaccination is one of the longstanding fears in the world; the first objectors appeared shortly after the first vaccination campaign launched by Dr. Edward Jenner in 1796; many objected to vaccination in Russia at the end of the 1990s.
Environmental pollution: some people feared that the civilization would come to end by 2020 due to sky-high levels of industrial and communal pollution which should result in a lack of oxygen and poisonous evaporation.
Asbestos: Micro particles of asbestos cause lung cancer. Asbestos was produced in Canada and the USSR. Canadian asbestos companies went bankrupt following an anti-asbestos propaganda campaign instigated by the competitors. Russia’s asbestos makers have survived the bad times. The incidence rate of cancer in the town of Asbest does not exceed an average national incidence rate of cancer.
Global warming: industrial emissions of carbon dioxide cause the greenhouse effect that leads to overheating of the earth’s surface. Consequently, polar ice will melt away causing the global ocean level rise by one meter.
Ozone holes: Freon used in refrigerators and deodorants will destroy the ozone layer of the atmosphere, which protects Earth against the harmful effects of ultraviolet radiation. As a result, the number of cancer and other deadly diseases will grow.

Hack sleep and screw yourself
by Neutron on Nov.18, 2005, under Fun, Health, Musings, News, Research
I got intrigued and set about to analyze the effects of such a sleep starvation on the mind, health and found puzzling pieces of facts. Here i present to you, my review article on “Sleep deprivation and its ill-effects”.
Disclaimer : This is a review post about the different articles i found with information, facts from those sites on hacking sleep, sleep cycles, problems that sleep deprivation can induce and my thoughts to manage a balance between lesser sleep and better health. Read on if you want to learn all about ‘Sleep’. Or so i lure you !
Sleep
Until the 1950s, most people thought of sleep as a passive, dormant part of our daily lives. We now know that our brains are very active during sleep. Moreover, sleep affects our daily functioning and our physical and mental health in many ways that we are just beginning to understand.
During sleep, we usually pass through five phases of sleep: stages 1, 2, 3, 4, and REM (rapid eye movement) sleep. These stages progress in a cycle from stage 1 to REM sleep, then the cycle starts over again with stage 1 (see figure 1). We spend almost 50 percent of our total sleep time in stage 2 sleep, about 20 percent in REM sleep, and the remaining 30 percent in the other stages. Infants, by contrast, spend about half of their sleep time in REM sleep.
The amount of sleep each person needs depends on many factors, including age. Infants generally require about 16 hours a day, while teenagers need about 9 hours on average. For most adults, 7 to 8 hours a night appears to be the best amount of sleep, although some people may need as few as 5 hours or as many as 10 hours of sleep each day. Women in the first 3 months of pregnancy often need several more hours of sleep than usual. The amount of sleep a person needs also increases if he or she has been deprived of sleep in previous days. Getting too little sleep creates a “sleep debt,” which is much like being overdrawn at a bank. Eventually, your body will demand that the debt be repaid. We don’t seem to adapt to getting less sleep than we need; while we may get used to a sleep-depriving schedule, our judgment, reaction time, and other functions are still impaired.
Although scientists are still trying to learn exactly why people need sleep, animal studies show that sleep is necessary for survival. Sleep appears necessary for our nervous systems to work properly. Too little sleep leaves us drowsy and unable to concentrate the next day. It also leads to impaired memory and physical performance and reduced ability to carry out math calculations. If sleep deprivation continues, hallucinations and mood swings may develop. Some experts believe sleep gives neurons used while we are awake a chance to shut down and repair themselves. Without sleep, neurons may become so depleted in energy or so polluted with byproducts of normal cellular activities that they begin to malfunction. Sleep also may give the brain a chance to exercise important neuronal connections that might otherwise deteriorate from lack of activity.
With this brief introduction into the physics of Sleep, let us see what some of the recent articles and posts have to say about ‘Polyphasic sleep’, ‘Hacking Sleep’ and their effects.
Polyphasic sleep is a sleep pattern specification intended to reduce sleep time to 2–5 hours daily. This is achieved by spreading out sleep into short naps of around 20–45 minutes throughout the day. This is supposed to allow for more waking hours with relatively high alertness.
The method uses natural human sleep mechanisms to maximize alertness when sleep time needs to be minimized. However, it requires a rigid schedule which makes it unfeasible for most people. It can work well for those engaged in activities which do not permit lengthy periods of sleep (e.g. sailors).
Again, several articles have been written recently about Polyphasic sleep and the attention it has gathered, forces me to look into the subject in detail. But first, let us look at the Sleep cycles and understand the different phases involved during a normal sleep routine before trying to attempt Polyphasic sleep.
To start off, let us look at a great article which has detailed analysis on the sleep cycles, phases, physiological effects, the natural rythm and factors that can affect a normal sleep. The article is very formal in nature and looks more like a technical paper, but we have to note that it thoroughly analyzes the different components that induce sleep, namely
1) The circadian component and
2) The homeostatic component
The author then talks about some of the habits that are misconceptualized in society about sleep and talks about some of the myths and discusses the implications of each. I definitely did learn a lot in this part. I am sure you will too !
Here’s a detailed look at the sleep cycles, the average duration of each cycle and which cycle is important to feel refreshed and to avoid the uneasy feeling even after 8 hours of sleep.
In the course of the night, we alternately enter two phases of sleep :
- NREM sleep (named for non-Rapid Eye Movement) – Scientists believe that NREM is the critical moment of memory consolidation in which the hippocampus(central memory switchboard of the brain) works as the neural trainer for the neocortex in which long-term memories will be stored. Those long-term memories cannot be formed without entering appropriates stages of the sleep cycle! You cannot learn effectively if your sleep gets cut short in the morning. Or if it gets interrupted during the night. Even if you try to sleep 15 hours per day in short pieces of interrupted sleep, your learning results will be dismal! Long story short, No NREM -> Not a solid long term memory.
- REM sleep (named for Rapid Eye Movement) – The brain in REM sleep is a hard-working brain that has little to do with the notion of energy-conservation and rest in sleep.
To learn more on sleep cycles, read the above article and The power of the Sleep Cycle. There are some interesting quotes in the article about ways to improve the alertness, fitness and health even with lesser sleep if proportioned rightly. This is very interesting.
Another article which created quite a buzz on ‘Polyphasic sleep’ is the ‘Uberman’s sleeping schedule‘. The recent article over at Kuro5hin talks about the Uberman’s sleeping schedule or Polyphasic sleep where the author manages to get just 3 hours of sleep everyday and freeing more time to work with 5-6 20-30 min short naps.
The idea behind this is to maximize the REM(rapid eye movement) sleep when your brain is still mostly active, conjuring dreams that we see. Interesting concept again but not quite workable if you don’t have the luxury to control your working time. Also, the effects mentioned in the article are only short term and the author has no clue about the long term effects of such a Uberman schedule. Definitely a risky bet IMO.
After reading the previous article, i was searching to find the effects of such a polyphasic sleeping schedule and stumbled upon another article which quotes and mentions the effects of polyphasic sleep from journal articles. Let us quote from ‘Ubersleep? Hacking Sleep? Stupid!‘
Like i guessed, there are some serious side effects to such polyphasic sleep. Here’s a small list of the long term effects that you need to be aware of before trying any of this.
- Your health will suffer
- Less sleep equals more fat
- People who sleep normally, live longer
- You increase your chances of having a car wreck
Some of it, i could have guessed by intuition but some of it has factual data to support it.
Based on the previous article, i suspected that maybe obesity is somehow related to sleep deprivation. Reason : I have been eating very less over the past few days combined with lesser sleep but i have still managed to gain over 3lbs in weight in the past month.
This article argues that ‘lack of sleep’ is a factor for obesity. The author also mentions couple of good stories and research attempts to discern the effects of the polyphasic sleep.
But oh well, no one is stopping anyone from trying polyphasic sleep but IMHO, dont try it, without researching the full effects of what it will do to you !
Moving on, i did find more scientific articles that have made observations on ‘What Losing Sleep Does to a Body‘.
While many aspects of sleep remain a mystery — including exactly why we sleep — the picture that appears to be emerging is that not sleeping enough or being awake in the wee hours runs counter to the body’s internal clock, throwing a host of basic bodily functions out of sync.“Lack of sleep disrupts every physiologic function in the body,” said Eve Van Cauter of the University of Chicago. “We have nothing in our biology that allows us to adapt to this behavior.”
The amount of necessary sleep varies from person to person, with some breezing through their days on just a few hours’ slumber and others barely functioning without a full 10 hours, experts say. But most people apparently need between about seven and nine hours, with studies indicating that an increased risk for disease starts to kick in when people get less than six or seven, experts say.
–Holy crap. If what they say is true, then i might have actually reduced my life span by atleast 10 yrs now for sleep starving myself over the past 6-7 years. Read this article too to learn some of the recent research activities being done to find out exactly the detrimental effects of inadequate sleep.
Another scientific article i found was ‘Down for the Count‘ which observes the sleeping habits of mammals in general.
“People who don’t have REM sleep are remarkably normal,” Dr. Siegel said. “There’s no evidence for any intellectual or emotional problems.”
So why do mammals and birds have REM sleep at all? “The best answer I can come up with is that it’s there to prepare you for waking,” Dr. Siegel said. “When the important work of sleep is done, REM sleep just makes you as alert as you can be while you’re asleep.”
–Well that rules out REM maximizing Ubersleep for me. Goodbye polyphasic sleep.
Now a few other articles suggest that “Deep Sleep May Be Genetic”. Eventhough the argument sounds appealing, i am very skeptical about the validity of such a thing. I think that deep sleep is directly related to a person’s stress level and ability to calm his mind. Hence, to get a deep sleep, I think that the psyche of a person matters and not the genes he derived from his parent. Well, i could be way off or closer than you think, but let further research prove me wrong.
In the light of learning scientifically about sleep, i feel obliged to link to another article that is based on sleep research. The article ‘Deep sleep short-circuits brain’s grid of connectivity‘ discusses how the brain functions during deep sleep. Here’s a quote from the article.
In the human brain, cells talk to one another through the routine exchange of electrical signals. But when people fall into a deep sleep, the higher regions of the brain – regions that during waking hours are a bustling grid of neural dialogue – apparently lose their ability to communicate effectively, causing consciousness to fade.
After reading so much about the different kinds of sleep cycles, methods to optimize sleep, i definitely felt that there is one other thing all the previous authors missed out. Meditation.
Meditation builds up the brain
What effect meditating has on the structure of the brain has also been a matter of some debate. Now Sara Lazar at the Massachusetts General Hospital in Boston, US, and colleagues have used MRI to compare 15 meditators, with experience ranging from 1 to 30 years, and 15 non-meditators.
They found that meditating actually increases the thickness of the cortex in areas involved in attention and sensory processing, such as the prefrontal cortex and the right anterior insula.
“You are exercising it while you meditate, and it gets bigger,†she says. The finding is in line with studies showing that accomplished musicians, athletes and linguists all have thickening in relevant areas of the cortex. It is further evidence, says Lazar, that yogis “aren’t just sitting there doing nothing”.
The growth of the cortex is not due to the growth of new neurons, she points out, but results from wider blood vessels, more supporting structures such as glia and astrocytes, and increased branching and connections.
-The research reinstates what we already know about the oriental methodologies involving meditation and the benefits of it. Theories apart, i have been practising meditation for well over 2 years although not very regularly and from my personal experience i can say for sure that if you do it right, it can compensate for hours of sleep deprivation. At the end of the meditative session, i usually feel alert, more conscious, and more alive. The symptoms of drowsiness and lethargy vanish and i am ready to do more work. It is important to understand the process of meditation to get the maximum benefit. The vital component is the ‘breathing’, which will determine how peaceful a feeling you are going to reach and the steadiness of your breathing will quicken the process. I am no where near an expert on this and i suggest that if you are interested, read up more or ask a professional.
Anyway, IMHO, meditation can definitely help me more than any theory on polyphasic sleep. But hey, no one is stopping you to try something different. And if it works, i’d be happy to know.
Diverging from the topic a little bit, on the topic of Alarm clocks, here’s another interesting article : ‘Alarm clocks are bad. How to wake up and feel better‘.
If you are one of those persons who relies heavily on alarm clocks to wake up in the morning, like i do, then you already know how irritating the sound of the alarm can be. But is there an easier way to wake us up with an alarm, without abruptly disrupting the sleep but to slowly ease in to getting up, and to avoid that groggy feeling after sleep ? Yes. The article provides an innovative method that aims to do that albeit expensive. In the end, another cool idea and a nice theory !
Here’s another scary finding ! An article that took sleep deprived doctors as test subjects has recently concluded that the attention, vigilance, driving skills suffer as much from long work hours & overnight shifts as from blood alcohol level of 0.04%.
Read more about ‘Lack of sleep affects young doctors just like alcohol‘.
In the end, there seems only one way to beat the time crunch. A ‘28 hour day schedule‘. I have thought about such an idea before but never realized that someone else would be interested on similar lines. Here’s the crux of the idea.
We know that there are 24 hours & 7 days in a week, a total of 168 hours. Instead, if we have 28 hours/day with a 6 day week period, we could have longer hours in a day, more time to work and more time to sleep. Voila ! But us humans, err, me i am sure, will still manage to work for 22 hours and get only 6 hours of sleep. Now i wonder how that would be like !
Conclusion :
Sleep well. Eat well. Life is probably(?!) not worth screwing around. My advice : Screw polyphasic sleep. Embrace meditation.
You only have one life to live. Enjoy it while it lasts.

Hot new fuel for nuclear reactors
by Neutron on Oct.13, 2005, under Nuclear, Research
First, you have the reactor core, loaded with nuclear fuel. Neutrons induce fission in a fuel element and once a fission occurs, it releases 2-3 more neutrons. If you can capture those fission neutrons and induce more fission, you end up with a sustaining chain reaction.
Now each fission reaction releases about 200 Mev of energy. That’s exactly 3.204E-11 Joules. That’s freakin miniscule but when we have enriched uranium with atomic densities > 1E22(btw, this is normal. Parallel : 1Kg of H2 has 6E23 atoms !), you could end up with net energies of about 3E11 J/s. This energy conducts out from the fuel, since there is a coolant flow in the core outside the pellet. Depending on the coolant’s heat capacity, some amount of heat is carried away by the coolant to the turbines, where with an awesome 30% efficiency, the heat is converted to power !
And that is a short gist of how Nuclear power is produced.
Now, back to my post. Here’s an article i read at NS. Look what it says below.
A Fuel pellet that is 50 per cent better at conducting heat will make nuclear power cheaper and more efficient, its developers claim.Engineers from Purdue University in West Lafayette, Indiana, added beryllium oxide to the standard uranium oxide pellets used in light water reactors. Because uranium oxide does not conduct heat well, pellets made of it tend to crack and degrade as the temperature of the reactor core rises and falls, and this means they have to be replaced before all the fuel has been used. Beryllium oxide is a better conductor of heat, so it allows the fuel pellet to cool more efficiently, says Alvin Solomon, who led the research. This means the combined pellet lasts much longer than the standard one.
This would mean a higher heat conduction out of the fuel to the coolant. If we use good coolants, like liquid metals, then we could extract more heat out and generate more power as a result. Since we are energy greedy beings by nature, this research has great value and potential in reducing the energy craving !
A-bomb system can warn of tsunami

“After the quake on 26 December, all geophysical researchers were looking for signals in their data,” Roger Bowman told the BBC News website.“One of the common ways was to make spectrographs – looking at how the spectrum of sound waves developed over time – and in this we saw the unique signal.”
The two researchers describe the unique signal found on spectrograph plots recorded by Indian Ocean hydrophones as a “chirp”.
What it means is that low-frequency vibrations are arriving before those of higher frequencies, producing a distinctive upward curving slope.
“In this frequency range – and these are very low frequencies, well below 1Hz – this is a unique signal,” said Dr Bowman.
As soon as i read the title, i had a moment, which drunkards call a “Moment of clarity”. It perfectly makes sense to make use of A-bomb detectors for monitoring seismic activity since they are more powerful than ordinary detectors and definitely would give lot more precise details as the exact location and range of the disturbance. And as always, they had to include the politics into science, making it tougher to implement. Get over it you fools. This is for a good cause.
Super-efficient N-reactors

Chinese scientists are planning to build super-efficient nuclear reactors by 2010 that can maximise uranium burn-up, minimise waste while quenching the energy crunch facing the communist giant.
If the first experimental reactor, set to be in operation by 2010, is successful, the technology could help relieve China’s uranium supply problems as the country accelerates nuclear power plant construction.
China Academy of Atomic Science President Zhao Zhixiang said a team of scientists has already mapped a detailed plan to speed up research and utilisation of the so-called next-generation fast reactors.
The new reactors are expected to burn 60-70 per cent of their uranium fuel — a conventional reactor consumes only 0.7 per cent of the uranium it is fed.
“This kind of reactor can greatly improve the efficiency of fuel burn-up, and we are trying our best to put the experimental reactor into use over the next five years,” Zhao was quoted as saying by China Daily.
Current reactors are only able to harness the power of 0.7 per cent of the radioactive isotopes found in natural uranium.
In the fast reactor, the process is optimised so that more of the previously untapped isotopes can be used to generate electricity, burning-up fuel at least 60 times more efficiently than in a normal reactor.
-Cool. Now i wonder what kind of reactors would that be ?! Even the chinese guy in my department didn’t have any idea about this but hey if this works, another thumbs up for Nuke power !
