Damn, now that song is going through my head. Who was that? Butch says it was Wild Cherry, but don’t hold me to it. Anyway, my friend Eric sent me a link to Michael Shermer’s site, to a page titled Miracle on Probability Street. He wrote it in 2004 but I thought I’d share it with you because it’s very good information.

We’ve all experienced a highly improbable event in our lives. Probably many, in fact. Some of us more than others, some more seemingly improbable than others. There is such a thing as the Law of Large Numbers that explains these coincidences and “miracles”.

The Law of Large Numbers simply stated (sans math): with a large enough sample many odd coincidences are likely to happen.

Coincidence: an occasion when two or more similar things happen at the same time, especially in a way that is unlikely and surprising.

Miracle: an unusual and mysterious event that is thought to have been caused by a god, or any very surprising and unexpected event.

On a side note, I was disappointed with Dictionary.com’s listing on these words so I thought I’d go to the Cambridge Dictionary. The definition above is from the Dictionary of British English. Out of curiosity, I looked up the word miracle in the Cambridge Dictionary of American English:

Miracle: an unusual and mysterious event that is thought to have been caused by God, or any surprising and unexpected event.

A very subtle but telling difference! I think I’ll be using the British version from now on. Read the rest of this entry »

Here is an amazing creature! Turritopsis nutricula is a hydrozoan, a jelly. They aren’t called jellyfish anymore, by the way. Now they are called jellies. Nom! Only I don’t want to eat this one on toast, I want scientists to study it. Why? Well, it’s basically immortal.

After it reaches sexual maturity, it can go through a process of transdifferentiation and transform mature cells back to young cells (polyps). Here’s one way to explain it:

Cell transdifferentiation is when the jellyfish “alters the differentiated state of the cell and transforms it into a new cell. In this process the medusa of the immortal jellyfish is transformed into the polyps of a new polyp colony. First, the umbrella reverts itself and then the tentacles and mesoglea get resorbed. The reverted medusa then attaches itself to the substrate by the end that had been at the opposite end of the umbrella and starts giving rise to new polyps to form the new colony. Theoretically, this process can go on infinitely, effectively rendering the jellyfish biologically immortal. (Wikipedia)

This little creature is about 4.5 mm in diameter (.18 inches). The red in the center is its large stomach. Young jellies have about 8 tentacles while adults have 80-90 tentacles. The picture shown below is actually a Turritopsis rubra from New Zealand which is closely related. They are very similar, but it’s not known if  T. rubra can transform back into polyps.

The jelly originated in the Carribbean but now it’s found all over the world in temperate to tropical oceans. Because it’s basically immortal (if it doesn’t succumb to predation, etc), the numbers are spiking.  They think it’s spreading by ships discharging ballast water in ports.

A bit more about their immortality: Read the rest of this entry »

My friend Brent sent me a link to a page on the web. It’s a conversation with Robert Sapolsky, a quiet, funny, apparently brilliant professor of biological sciences at Stanford University and of neurology at Stanford’s School of Medicine. Professor Sapolsky has written several books such as:

The link Brent sent me was called TOXO and he suggested it to me because our book club is reading The God Virus: How religion infects our lives and culture, by Daniel W Ray. Now the video on that page was Robert Sapolsky talking about a most interesting parasite called Toxoplasma. This is what pregnant women need to worry about, and why they avoid cats and cat feces. It can wreak havoc on their unborn baby’s nervous system.

If you read The God Virus, which talks about parasites and viruses as an analogy for religion, I highly recommend watching this video. If you aren’t going to read the book I still recommend the video. The transcript is underneath it too, which will make it even more accessible for you. But the video is longer than the transcript. So take 25 minutes and enjoy it. Here’s another link to the video. I’m telling you, it’s fascinating. As I mentioned, the video is longer than the transcript. He goes into telemeres and molecular age, which I heard a study about recently confirming what he is explaining.

What he’s talking about touches on evolution, common ancestors, parasites and how they go about getting where they need to be, motorcyclists and speed freaks, and schizophrenics, as well as the government’s interest in this parasite. A wild ride indeed! Read the rest of this entry »

The other day, I watched a 3 part special about what makes us uniquely human from the rest of the animals on the planet, namely chimps. It was very interesting and I wanted to share it with you. I’m linking to each full length video and then below I will link to Science Talk’s interviews with Alda about the show and other interesting things.

Here’s some information from PBS:

After some three and a half billion years of life’s evolution on this planet – and after almost two million years since people recognizable as human first walked its surface – a new human burst upon the scene, apparently unannounced.

It was us.

Until then our ancestors had shared the planet with other human species. But soon there was only us, possessors of something that gave us unprecedented power over our environment and everything else alive. That something was – is – the Human Spark.

What is the nature of human uniqueness? Where did the Human Spark ignite, and when? And perhaps most tantalizingly, why?

In a three-part series broadcast on PBS in January 2010, Alan Alda takes these questions personally, visiting with dozens of scientists on three continents, and participating directly in many experiments – including the detailed examination of his own brain. Read the rest of this entry »

DestructionCyril of Alexandria was born around 376CE and rose to power as the Pope of Alexandria during the peak of the Roman Empire’s rule there. He is credited with leading the charge against Nestorius in the First Council of Ephesus, where the divinity and caricature of Jesus Christ were debated. The Roman Catholic church eventually bestowed sainthood upon him, counting him among the ‘Church Fathers’ and ‘Doctors of the Church’, and also titling him as a Pillar of Faith and Seal of all the Fathers.

History might credit him with a much darker deed though, not surprisingly one the church usually fails to mention or attempts to brush under the rug. Although not official of course, some have referred to him as the patron saint of arsonists. His leadership possibly brought about what is probably the single most destructive annihilation of knowledge in human history. Read the rest of this entry »

An interesting offer from ASPEX
November 10, 2009 2:54 PM – by PZ Myers

I had my doubts about this; I got an offer from ASPEX corporation to let people get free scanning electron micrographs of just about anything. They make a desktop SEM (Scanning Electron Micrograph), and all you have to do is fill out a form and mail it in with your sample of a dead bug or a microchip or bacon, and presto, within a few weeks they’ll have it scanned in and the image available on their website.

I asked them if they knew how many readers I have, and they said no problem, they can handle it.

Huh.

Well, you heard them. Scavenge your trash cans, dig into your local sources of vermin and oddments, and send them in. I’m thinking this could be really fun for any school teachers out there — you could have the whole class looking for interesting specimens to zoom in on. You can see their current galleries for ideas.

Follow the instructions here to get your dead bugs and rotten food scanned for free.

If you do send something in to get scanned be sure to note that you found them via PZ; and be sure to come back here and share your scan with the rest of us!

funny-pictures-interesting-catHello everyone,

First, I am now a Google Waver! Find me at zeneece@googlewave.com. I started my first public wave for atheists: Atheists Unite!

Secondly, I must confess my ignorance on a certain matter that has been bouncing around my brain for some time. I have asked my genius husband Butch and he didn’t have an answer, which made me feel better.

I’ll start with an example:

I always thought aspirin was found in the bark of white willows, and then was made in the lab. But the history seems to be entirely in the laboratory, according to Wikipedia. Also there does seem to be a connection between white willow bark and eventually aspirin.

Needless to say these days, aspirin is made strictly in the lab/factory. My question is, if things are made strictly from chemicals, where do the chemicals themselves come from? And a followup question would be, wouldn’t that make everything natural, at some point? Doesn’t everything eventually lead back to nature?

Another example:

Black Gold, petroleum, crude oil. It’s considered this unnatural thing. But didn’t it come from rotting vegetation and other natural organic matter?

When does something natural become something synthetic?

Why are natural things considered superior to synthetic things nowadays? Is there some proof that it’s true? Or is it marketing/propaganda?

I’m not trying to start anything, or as the Brits would say, I’m not trying to have a go at synthetics. I really just want to understand. If the red food dye and flavoring in my drink stick mix is synthetic, where did the chemicals that make it up come from?

I would love your feedback and thoughts on this. But please, I took chemistry in high school which was over 20 years ago (egads, that made me feel old), so keep it simple.

Thanks friends! :)
