Banding on Penguins Not Such a Good Idea Afterall

Climate change can be assessed through using the top predators of the Southern Oceans, the penguins. However, a recent study published on Nature have shown that the use of flipper banding may affect one specific population of King Penguins.

The 10-year study indicates that “banded birds produced 39% fewer chicks and had a survival rate 16% lower than non-banded birds“. This finding from the research team from the University of Strasbourg in France brings to the surface the effect of banding on animals, specifically the penguins in order to collect scientific data.

However, the conclusion on the tagging and bands are by no means clear, according to interview with two penguin experts. One of them, Dee Boersma, at the University of Washington stresses that not all bands are created equal, thus the effect on species may be different with different materials, shapes, sizes of the bands.

The study in the end stresses the importance of reconsidering the data collected of the effects of global warming on marine ecosystems from flipper-bands.

13th Zodiac Sign: Ophiuchus….?

“I will not settle for being a PISCES!! I’m so sad! I want to stay an ARIES!!”

“Eww I’m a Taurus!!! NOOOOOO!!!

          These were just a couple of the status updates that we saw all across the social web on January 14th, when news started to come out of the addition of a 13th zodiac sign. The new sign was called Ophiuchus. Now for some this may not matter, but for those people who avidly check their horoscope or even have a tattoo of their zodiac sign this was bad news because it initially meant a shift in zodiac signs for everyone.

So why do we have the new zodiac sign?

             According to the initial comments made by an astronomer by the name of Parke Kunkle from Minnesota, the Earth has been wobbling slightly on its axis due to the gravitational pulls from the Moon; thereby changing its position with relation to the Sun. According to him the change has been enough to change the dates of zodiac signs and has also made it necessary to add a 13th sign, Ophiuchus.

So is this really “new” news? Does this mean we have different horoscopes readings/signs?

        No, because according to popular astronomers such as Susan Miller as well as the more recent clarified statements made by Parke Kunkle stated that  none of this is actual new information, and according to them “astronomers have known this since 130 B.C”. Furthermore, this has no effect on our horoscope readings here in the West because Western astrologers use the Tropical zodiac where as Vedic astrologers, such as those based in India use the Sidereal zodiac. “The Tropical zodiac is based on the movement of the seasons where as the Sidereal zodiac is based on the actual positioning of the stars.” This is important because as the Earth shifts Vedic astrology changes along with it. So while this 13th sign might be important to Vedic astrologers, to us in the West nothing changes and our zodiac signs and dates stay intact.

              Hopefully this will clear up any concerns that you may have had about your sign. I also think this serves as a great reminder for all of us on the importance of always doing our research before we get caught up in all the media hoopla that surrounds us.

The Origin of Our Solar System

Has anyone ever wondered about how the world, and our solar system started? I have countless times, but I am still questioning our current theory of origin, the Nebular Hypothesis. http://en.wikipedia.org/wiki/Nebular_hypothesis

A. solar nebula B. contraction into rotating disk C. Cooling causing condensing into tiny (dust sized) solid particles D. Collisions between these form larger bodies E. These accrete to form planets

First proposed by Emanuel Swedenborg, the Nebular Hypothesis is the most widely accepted theory for the origin of our solar system. It is based upon the assumption that the universe already exists under the Big Bang theory. Under this model, the  molecular hydrogen and “dust particles” had clumped together to form a giant cloud, called a nebula. Due to their own gravity, they collapsed, spiralling down to the centre of the cloud to form a central mass and a rotating flattened disk. High concentration in the center of the cloud lead to temperature and pressure increases, and resulted in nuclear fusion.

Nuclear fusion was the process of which hydrogen molecules fused together, released energy and formed the Sun. The “leftover” dust clumps became the planets, and this is the current theory of how the Solar System came to be. It explains why the planets revolve around the Sun on the ecliptic plane, and the proximity of terrestrial planets and gaseous planets.

However, I question how the hydrogen molecules came together to make a giant ball in the first place. I thought that gaseous molecules have a tendency to go from areas of high concentration to low concentration. Did the gravity of one hydrogen molecule attract another hydrogen molecule, and eventually became a huge giant cloud of hydrogen, and suddenly collapse? The force of gravity of one hydrogen atom to another would not be such a significant force, as Fg = km1m2/ r2, and the constant, k is a very small number of 9.0*10-9.

I am sceptical. What about the second law of thermodynamics, entropy? Molecules want to increase their entropy, and disperse when they can. Would there be any other forces that attracted the hydrogen molecules and dust particles together besides the force of gravity? Perhaps one day, we will be able to understand the mechanisms of our world better.

Network Neutrality: An Essential Ingredient for Continued Internet Innovation

From the boardroom to the legislature, an important policy debate is taking place. Even though it has the potential to fundamentally reshape nearly every aspect of our modern digital lives: how we connect, communicate and entertain ourselves, the public remains woefully misinformed. The debate is over Network Neutrality, and the related issues of packet prioritization and usage-based billing. In recent years, ISPs who have traditionally just provided network-access have become increasingly interested in “value-added” services, such as internet-telephony or IPTV. Rather than having these services compete on merit, many ISPs have decided to degrade the network performance of competing offerings, prioritize their-own traffic, and to limit monthly bandwidth. Net-neutrality is the opposite of all that. It is a network design principle mandating that all packets, or parcels of data, should be treated equally, sent or received on a first come first service basis.  A carrier should not be allowed to prioritize traffic.

I was reading an article on Google News the other day (Internet groups criticize CRTC bandwidth ruling) and upon browsing through the comments was struck by the misinformation I saw.  Network carriers such as Bell Canada (TSX:BCE) and Verizon (NYSE:VZ) have somewhat successfully argued that these network-management techniques are required to justify investment in expanded infrastructure, with John Thorne, deputy general counsel for Verizon being quoted as saying that: “The network builders are spending a fortune constructing and maintaining the networks that Google intends to ride on with nothing but cheap servers.”  The debate has been manipulated so that the battle for bandwidth looks appears to be pitting the everyday citizen trying to access their email and the college student down the block using P2P programs 24/7. While arguments such as this have some merit, they are for the most part facetious, have severe long-term consequences and from a public policy point of view not well thought out.

Part of what has made the internet-era so incredible is the dynamism that comes from enabling anyone with a great idea to reach the entire world. Take a moment and think about how the web has changed your life for the better.  Think of the products and services you use most often. Now imagine a world without them. Let’s say your ISP, which has an IPTV service, has decided to cap your monthly download limit and charge overage fees, while allowing you to access their IPTV services for no extra charge. Companies like Netflix and YouTube just couldn’t compete.  They’d be priced out of the market.  Or what if large incumbents could pay for priority access; services such as Skype might be given a lower priority then your ISP’s VOIP service. You forgo Skype not because it’s an inferior product but because its call quality has purposefully been degraded. For these reasons, amongst others, it is essential that the public be well informed about the facts surrounding network neutrality and how this seemingly trivial policy debate has the potential to dramatically alter the world’s economic landscape for decades to come.

What to trust in making decisions; Cognitive thinking or Sientific methods?

We have all evolved to associate one thing to the other. We associate by thinking; finding and looking for meaningful patterns in our surroundings. Another reliable way to associate one thing to the other is by the use of scientific methods. The problem over  here is what to trust in  making a decision, our cognitive thinking or the scientific method?

In recent years, there has been a seeming connection between autism and MMR-vaccines. The parents of the children diagnosed of Autism, are trying to look for a causal link between this complex developmental disability and vaccines that the children had received.

In 1998, a British surgeon, Andrew Wakefield, published a paper claiming that the MMR-vaccine had a causal link to Autism. He proposed that the measles virus traveled to the children’s intestines causing intestinal damage. This damage then allowed brain damaging proteins to enter their blood stream. Dr.Wakefield used stories of 8 children who had developed symptoms of autism within a month of receiving the vaccines.

Here is the article from Wall street Journal that i came across Junk Science Isn\’t a Victimless Crime.

These findings fueled the debate over vaccine safety and lead many people to a general distrust in vaccines.

This type of study has been replicated many times around the world and each time no causal  link has been found. The following two articles from New Scientist proves that MMR-vaccine has no causal link to Autism; Autism rises Despite MMR Ban in Japan and MMR and Autism not linked, finds giant study.

I do not think Dr. Wakefield’s paper was statistically right. He based his conclusion on a very small sample size (about 12 children). He should have used  a way larger sample size as in the other two studies disproving the existence of a causal link (more than 30,000 or half a million children).

Overall, What do we believe; Is there a causal link between MMR-vaccine and Autism? In spite of knowing that the research linking MMR-vaccine to Autism has some discrepancies, we still feel that there is a link. Do not forget we have the ability to overcome our feelings in a situation and replace them with a logical and scientific reasoning that would serve us better and help us advance in life.

If further interested, here is part 1 of 10 of Dr. Andrew Wakefield’s interview on his MMR study by Dr. Mercola.
