Some people might suggest the nautilus as the ancestor of modern squid, since they're the only "ancient-looking" cephalopods most of us have seen. But the lineage that led to modern nautiluses and the lineage that led to modern squid diverged long before there was anything that looked like a squid.

Here is a tree of evolutionary relationships within the Cephalopoda, from the magnificent Tree of Life website.

The three problems of humanity were outlined in a talk by Nick Bostrom (of Oxford University, UK) at TED in April 2009.  While I'm sure there are some that will consider these points to be quite reasonable in setting goals, I'm continuously amazed at the lack of rigor or introspection these claims aim at.  

In a nutshell, the talk identified three (3) problems that were perceived as needing to be addressed to "fix" humanity. In this article, I will discuss the first one.

Problem #1:  Death is a BIG problem.

Botulinum Toxin A is a commonly used cosmetic treatment, where the drug paralyzes small muscles in the face to reduce the appearance of wrinkles.   If you have ever seen someone who looks normal and then suddenly looks like The Joker, you have seen Botox in action.   A new study by researchers at the Faculty of Kinesiology, University of Calgary, is raising questions about the therapeutic use of botulinum toxin A.

What happens when you die? What's right and wrong? What's the purpose of life? Aaaaarrghhh! Chill out, God has the answers. And the religious part of your brain knows it.

The anterior cingulated cortex is the human home of anxiety. And it's increasingly chill in people with religious conviction. In fact this anxiety center is quieter in people with any strong convictions that answer big questions, including conservative political ideologies. (Lest ye nail this author to the cross of liberal media bias, this is not necessarily a bad thing: it seems that many people could benefit from a chill pill shoved into their brain's anxiety center.)

If you are unaware, a supernova is an exploding star. In certain types of supernovae, the detonation starts with a flame ball buried deep inside a white dwarf and the flame ball is much lighter than its surroundings, so it rises rapidly making a plume topped with an accelerating smoke ring.

A team of physicists have mimicked this type explosion of a supernova in miniature.

“We created a smaller version of this process by triggering a special chemical reaction in a closed container that generates similar plumes and vortex rings,” says Stephen Morris, a University of Toronto physics professor.

A new study says that exposure to polluted air in young mice led to an accumulation of abdominal fat and insulin resistance even if they ate a normal diet.   

The U.S. Environmental Protection Agency(EPA) says that nearly one out of every three people in the United States is at a higher risk of experiencing health effects related to the presence of polluted air.   Because of the tiny size of fine-particulate air pollution - 2.5 micrometers or smaller in diameter, or about 1/30th of the average width of a human hair - pollutants could reach deep areas of the lungs and other organs in the body.

Bacteria that we carry in our bodies may help decide who we marry, according to a new study that analyzes the gut of...a small fruit fly. 

A group of molecular biologists recently demonstrated that the symbiotic bacteria inside a fruit fly greatly influence its choice of mates.  They propose that the basic unit of natural selection is not the individual living organism, plant or animal, but rather a larger biological milieu called a holobiont. This milieu can include plant or animal life as well as their symbiotic partners. In the case of animals, these partners tend to be microorganisms like intestinal bacteria.
