I recently watched a program on the Science Channel entitled "Human Nature: Born to Kill".  In this episode, part of the objective was to explore humans killing other humans.  Of course, the usual array of topics were raised, from evolutionary psychology to genes [i.e. the "warrior gene"] and even the "nature vs nurture debate".

However, there were a few points that I felt were muddled and confused.

"Organic" food and products is a $29 billion big business and its marketing power is very strong: studies have shown that this simple label can lead us to think that a food is healthier, what is known as the 'health halo effect'.  Marketing attempts to penalize conventional food would also capitalize on that bias, making genetically modified food seem less healthy.  

A new paper by Cornell University's Food and Brand Lab out to to determine if an organic label can influence much more than health views: they found hat perceptions of taste, calories and value can be significantly altered when a food is labeled "organic". And certain people are more susceptible to 'health halo' marketing.

Men with Lynch syndrome, an inherited genetic condition linked to a higher risk of several types of cancer, face a higher lifetime risk of developing prostate cancer and appear to develop the disease at an earlier age, according to a new study.

People with Lynch syndrome have up to 80 percent lifetime risk of colorectal cancer and are also more likely to develop endometrial, gastric, ovarian, urinary tract, pancreatic and brain tumors. Overall, about 1 in 440 people are carriers for the genetic mutation, making it one of the most common inherited cancer conditions.

An experiment using microvesicles generated from mesenchymal bone marrow cells to treat cancer, neurological researchers at Henry Ford Hospital have discovered a novel approach for treatment of tumor.

Specifically, the research team found that introducing genetic material produced by mesenchymal bone marrow cells significantly reduced a particularly resistant form of malignant brain tumor in living lab rats.

This is a fairly new problem, being traced back to as recently as 2003. However, it also has the kind of counter-intuitive solution that has made it a favourite on mathematical websites and forums. In its various retellings, it sometimes suffers from a lack of stringent conditions that result in rather imaginative solutions; perfectly legitimate solutions within the parameters set but not always the ‘classic’ one. If you’ve seen this before, then speed-read to the end where we take the side of the jailer!

What looks like a tantalizing signal of the rare two-muon decay of the Higgs boson has been evidenced in an analysis of 2011+2012 data just sent to PRL by the CMS collaboration. This analysis targeted supersymmetric neutral Higgs bosons, whose decay to muon pairs is enhanced for some values of the SUSY parameters, but was not expecting to see any signal in the 25 inverse femtobarns of collisions that the CMS experiment has so far collected.

When making holiday plans, golf is number 938 on my to-do list. Sure I can appreciate the energy transformations involved in swinging a club, deforming the ball and projecting it along a parabolic trajectory while dimples reduce drag. Indeed, the consistency of body mechanics and correct choice of club increase the likelihood that the ball will reach the right altitude and take the most direct path to the green. Psychologically, yes, it's nice to control one's emotions and play more efficiently, but I get a bigger thrill from finding someone else's ball in the woods than from sinking a long putt. -->

So you want to be in the energy biz. Do you have what it takes? It’s April Fools' Day--- test your energy IQ and find out where you belong in the dynamic energy sector.

Prefabricated Housing
1) Is prefabricated housing cheaper and/or greener than stud built construction?
2) Did a Chinese developer build a prefabricated 30 story hotel in 15 days?

Oil Pipelines
3) Canada has a glut of oil and gives the United States bargain pricing. So, why does the United States buy oil from Venezuela?
4) For the Keystone XL Pipeline, what does the XL stand for? Hint, don’t confuse pipelines with men’s boxer shorts. -->

Globally existential threats due to ‘overpopulation momentum’ together with the top-heavy age structure leave by now no alternative to radical technological adaptation for anything that wants to survive 'long term'.  It is strictly too late to ‘go green’ except via a novel take on what constitutes ‘green’, including synthetic biology.  Hyped for a long time, nanoscience is still largely in its pioneering phase.  However, it matures as we speak and soon, as it becomes true nanotechnology, it will leave the hype far behind.

When I was a kid, I would happily play around with both words and numbers – I still do. Both have their aesthetic appeal. Whether it is constructing and deconstructing mathematical puzzles or cryptic crosswords, they appear as small artefacts that reveal a grander architecture. Combine this with the serendipity of the internet, and Pi Day was just a hop, skip and jump away from Richard Feynman and pilish poetry.

Cross-disciplinary  academic progress in vagueness has recently been augmented  with a paper from Prof. PhDr. Jarmila Tárnyiková CSc. at Palacký University, in Olomouc, Czech Republic.

The professor has authored one of the very few papers to examine and compare English and Czech Non-numerical Vague Quantifiers (also known as Vague Non-numerical Quantifiers – VnQs).
Some examples from the paper :

• Piles of
• Oodles of
• Mountains of
• A Smidgen of

What if I told you that fictional mysteries contain practical real-world methodologies? I have pointed out the similarities between detectives solving mysteries to software debugging before. My day job of writing code often involves fixing bugs or solving bizarre cases of bad behavior in complex systems.

In a new book called Mastermind: How to Think Like Sherlock Holmes, Maria Konnikova also compares the mental approaches of a detective to non-detective thinking [1].

An autonomous robotic jellyfish the size and weight of a grown man has been developed. 

Nicknamed Cyro, this prototype is a larger model of the robotic jellyfish (named RoboJelly) the same team unveiled in 2012. RoboJelly is roughly the size of a man's hand, typical of jellyfish found along beaches.

Antidepressants are commonly prescribed for depression but their efficacy is questionable -   many people don't experience symptom relief.

The National Institute of Mental Health's STAR*D study, the largest and longest study ever conducted to evaluate depression treatment, may have a better way;  identifying predictors of antidepressant response. f

Researchers in the Sheffield Centre for Robotics have been working to program a group of 40 robots that 'swarm' together to carry out jobs. So far, they have demonstrated that the swarm can carry out simple fetching and carrying tasks, by grouping around an object and working together to push it across a surface.  

The robots can also group themselves together into a single cluster after being scattered across a room, and organize themselves by order of priority.  The programming for that part is simple. If the robots are being asked to group together, each robot only needs to be able to work out if there is another robot in front of it. If there is, it turns on the spot; if there isn't, it moves in a wider circle until it finds one.

A recent article entitled "Monsanto v Monarch Butterflies" begins by examining the argument that GMO foods are impacting the population of Monarch butterflies.  There are enough references and quotes that indicate that this assertion isn't particularly viable and that it isn't likely that Bt toxin plays any role in the issues facing Monarchs.

So far so good.

Most stars do not form in isolation, but are in clusters ranging from dozens to thousands of stars.  

Even in our galaxy, the Milky Way, with stars more than 13 billion years old, has a lot of young, hot action: new objects form and others are destroyed.  NGC 2547 is an example.

How young is young, cosmically? Considering that our Sun is 4.6 billion years old and has not yet reached middle age, NGC 2547's stars ranging from 20 to 35 million years old is really young. If you imagine that our Sun as a 40 year-old person, the bright stars in the picture below are three-month-old babies.
