HeLa cellsWhile listening to CBC Radio One yesterday (I am now an addict), I heard an astonishing scientific story regarding HeLa cells. The name of the cell comes the name of Henrietta Lacks, a Virginian tobacco farmer whose cells became, and still are, a gift to medical research. An article on the Smithsonian website discusses the importance of her cells when they write:

“Henrietta’s cells were the first immortal human cells ever grown in culture. They were essential to developing the polio vaccine. They went up in the first space missions to see what would happen to cells in zero gravity. Many scientific landmarks since then have used her cells, including cloning, gene mapping and in vitro fertilization.”

What makes the story so interesting are the interactions Henrietta and the Lacks family had with doctors and researchers, both before and after her death and the impact these interactions have had on all of scientific research.  There are misleading doctors, misleading researchers, inmate experimentation, misunderstandings and many other things that come up in the story, which began in the late 1940′s. Rather than rehash the information myself, I recommend checking out a few of the following resources if you are interested in reading more.

Mother Nature Network logoThe folks over at the Mother Nature Network recently posted a slideshow featuring “11 Intriguing Transparent Animals”. While you may have seen a couple of these images before, there are a few that are particularly incredible – the barreleye and its transparent head comes to mind!

Sonic boom

The great people over at Environmental Graffiti have posted a great snapshot article of ten amazing photos of sonic booms. In addition to the great photos, Environmental Graffiti discusses each image in detail. For the image above:

“This stunning shot is just as cinematic as it looks – in fact it was taken for Columbia Picture’s visual effects unit, for a sequence in the film ‘Stealth’ on board USS Carl Vinson (CVN 70). It shows the Commanding Officer of the ‘Black Cocks Down’ of Marine Fighter Attack Squadron Three One Four (VMFA-314) reaching supersonic speeds off the bow of the nuclear aircraft carrier. How loud a sonic boom sounds depends on how far away it is from the person hearing it. Because planes are pretty far away, it sounds like a deep double boom, but in the case of a bull whip, when it is close, it is a fireworks-type crack. You can imagine that if the planes above were seen as close as they seem to have been, it would have been a pretty deafening noise.” (Environmental Graffiti)

New Life on Earth?

A few days ago NASA decided to hold a breaking news regarding a new scientific discovery that had the potential to change the way we view life. Well, it turns out that the “breaking news” announcement, while still a hefty discovery, was largely underwhelming. A good friend of mine was live-blogging the announcement and has a very detailed account and summary of the entire event.

UPDATE: The stick-figure comic site, xkcd, has even taken a shot at the lackluster event.
