Hormone-Free Turkeys? Of Course!

In the last few days, as Thanksgiving here in the United States has approached,  I’ve seen the graphic below shared across Facebook by friends and family. At first I ignored it, as I tend to ignore most image memes I come across; but this one intrigued me because it seemed to run counter to the standard image meme fare.

IMO: What would it take to change your mind?

Via https://www.flickr.com/photos/danieltoschlaeger/9409678513/

As critical thinkers and skeptics, it is important that we understand our own beliefs and accepted facts. Take to heart the words of physicist Richard Feynman who observed, “The first principle is that you must not fool yourself—and you are the easiest to fool.” His essay, “Cargo Cult Science,” is well worth a read, even if you’ve already read it. One of the primary jobs of the scientific method is to protect us from our own biases and mistakes—to help us not fool ourselves. / read more…

The Top Conspiracy Theories of 2014

PLEASE NOTE: This list is based on a forthcoming piece I’ve written for Ranker.com, where I’ve been developing content for the past several months. When it comes to conspiracies, there’s no limit to what can be written.

2014 brought conspiracies on top of plots on top of evil cabals tossing out false flag distractions. Whether it was plane crashes, murders, diseases or general nonsense, if you think someone somewhere was plotting to destroy you, you probably found a conspiracy theory to go along with your tinfoil ravings.

Here are ten of the best (but by no means ALL) conspiracy theories of 2014.

Is Soda Bad For You?

Tumbler_of_cola_with_iceThis is a reader-recommended topic. In the comments to my post “Please Don’t Tell My Daughter There Are ‘Chemicals’ In Her Soda,” ‘Kristin’ said:

Sodas ARE bad for you. It’s a fact, and believe it or not I’m not trying to scare you. If you feel other wise of course you have a right to your own opinion. It seems you feel offended because the soda you enjoyed as a child (yes, it would naturally bring up nostalgic feelings) is being called ‘bad’. Maybe you should do some research and write from the realm of knowledge rather than from a state of defensiveness.

Assumptions about my lack of research aside, I think ‘Kristin’ has offered up a splendid idea! Are sodas bad for you, blanket-statement-full-stop? Let’s find out.

In the past couple weeks I have done more research, and I have quickly discovered something. In order to answer the question “Are sodas bad for you?” it turns out we need to ask two other questions: What’s in the soda? and How much soda is being consumed?

How the Ghost Rider Coped with a Terrible Loss

Rush is one of those rock bands that doesn’t get enough recognition for their amazing musicianship and incredible career. It’s difficult to define them in a single sentence, their musical style evolved over the years. Starting out as a prog rock band, with a first album in 1974 (influenced by Led Zeppelin and Pink Floyd), they evolved into more hard rock with a brief synthesizer intermezzo, defining in essence their own genre. What didn’t change over the years is their incredible talent for playing music, especially live. No wonder, then, that they seem to have a relatively small but very engaged group of fans.

Captain Cook and the Impossible Cotton

Shortly before Captain James Cook was killed on the island of Hawaii in 1779, one of his botanists, David Nelson, made a single four-day excursion up Mauna Loa and collected 136 species of plants. From Reader’s Digest‘s 1986 book, Mysteries of the Ancient Americas:

When Captain Cook landed in 1778, Hawaiian cotton—a wild hybrid species with one set of chromosomes from New World cotton and another from Old World cotton—was already well established. How did it get to be a hybrid, and how did it get to Hawaii? … If Old World people and New World people each brought their respective cotton plants to Hawaii, and the hybridization occurred there, where are the two parent species?

This struck me as a true puzzle, and more importantly, one with far-reaching implications. Such a plant might well overturn much of what we’ve learned about the prehistoric colonization of the Americas and the Pacific islands. Our studies have taught us that no genetic link exists between the original populations of these two regions, but proof that such a crop existed could throw a serious monkey wrench into that knowledge.

Stop Hating Common Core Math

common-core-mathIf you are an international reader, you may not have heard of Common Core, which is purely a “thing” within the U.S. It’s a push to standardize learning levels across the country, and also to introduce new approaches to what are often decades-old teaching methods.

If you are a State-side reader, you probably haven’t been able to avoid hearing about it, especially if you’re active on social networks. Common Core mathematics, in particular, has become a lightning rod for criticism, the new “poster child” for what’s wrong with the public school system. Examples of Common Core math (like the one pictured to the right) have gone viral across Facebook and Pinterest, and political pundits have pounced on these examples (and others) to excoriate the Common Core approach. There’s no doubt about it: people hate Common Core math.

But they shouldn’t.

Amelia Earhart Mystery Solved?

If you pay attention to recent media reports you may think that the mystery surrounding Amelia Earhart’s last flight has been solved, and that researchers have in fact found wreckage from her flight. Headlines read: “Mystery of Amelia Earhart Solved? Fragment From Missing Plane Identified,” and “Mystery of Amelia Earhart finally solved,” and “Amelia Earhart mystery – 1937 photograph could be clue to fate of aviator who disappeared on round-the-world flight.”

Those headlines were based on a recent press release and quotes from a particular researcher who has found a metal fragment, and claimed, “It was as unique to her particular aircraft as a fingerprint is to an individual,” and the patch “matches that fingerprint in many respects.

What does this mean? Is the mystery solved as it has been widely reported, or is this just another example of researcher enthusiasm? Lets revisit Ms. Earhart’s fateful flight and take a skeptical look at this “new” evidence.

Gravitational Waves and the Value of Errors

Imagine a fat guy doing a cannonball into a calm swimming pool. We can predict that a minute later the surface of the pool will be mottled with waves: ridges and valleys, peaks and pits. The Standard Model of cosmology makes a similar prediction, that the rapid inflation of space after the Big Bang left it mottled with gravitational waves where space itself expands and contracts, much like the movement of water molecules on the surface of the pool. We could sprinkle pepper on the pool to easily observe and measure the waves. Nature has already done this for us in space: the light from cosmic background radiation gets polarized as it passes through the peaks and pits of gravitational waves, allowing us to observe the waves indirectly.

Do You Need Organic Baby Formula?

When it comes to feeding our babies, it’s natural to only want the best. And while pediatric nutrition experts generally agree that “the best” for babies is breastfeeding, there are innumerable mothers who, for whatever reason, have to rely on other methods. This is where formula comes in. While breastfeeding has been making a major comeback in pediatrics and culture over the last few decades, formula continues to serve as either an alternative food source or a supplement.

baby-formula

Few issues have caused more pitched battles in the “mommy wars” than that of breastfeeding vs. formula. It’s a topic fraught with landmines and traps, as personal anecdotes butt heads with each other and everyone throws their two cents in about what worked for their baby, what they think you should do and what they’d never, ever do. Obviously, it’s an intensely personal and individualized thing to talk about. But within that war is a smaller skirmish, and one that’s primarily fought in the wealthy neighborhoods of big cities: organic formula vs. regular.

Does a baby who needs formula need organic formula? Is it better? Why is it better? And is there even a difference? / read more…
