Fast Tracked

One of several motor proteins used to move cellular components around, dynein typically operates by latching onto a cargo, then dragging it along tracks laid down by cytoskeletal filaments called microtubules. Yet scientists studying egg production in the fruit fly Drosophila melanogaster recently described a totally different mode of action. In the egg chamber of female Drosophila (pictured), nurse cells (to the left) provide the developing oocyte (right) with proteins, organelles and RNA, through intercellular connections known as ring canals (pink, with microtubules in white). There, instead of shuttling cargo as usual, dynein, anchored to the inside of the cell membrane, moves the microtubules themselves, gliding them through; this motion drags cytoplasm along, bringing large amounts of particles with it for bulk delivery. As dynein is highly-conserved across species, and ring canals have also been found in egg-producing cells in vertebrates, including humans, this 'go-with-the-flow' transport could occur more widely.

This is an example of what the egg chamber in the sea turtle nests look like. This was as deep as your elbow and this sand was packed meaning patted down and hard. The sea turtles use their back flippers to carefully dig this out to lay their eggs. It amazes me how perfectly round each nest is. Sea turtles lay ~100 eggs per nest. After a few months, the babies emerge. The sex of the turtle is determined by the temperature of the sand. Warm temps produce females and cold temps produce males. If the temperature is neither to hot or to cold, the nest produces both males and females.

Not content to merely release awesome Alien action figures in classic Kenner style, Funko (along with Super7) has announced an incredible playset right out of the ’70s to accompany them. It’s perfect, right down to its packaging. Look how excited that little girl is to be playing with her Alien Egg Chamber!

Kane and the eggs.  

How did they get there? We may soon find out.

4th Doctor Who: 'The Invisible Enemy' Gaffe

You may have to enlarge the picture a bit to see what is going on here, but in The Invisible Enemy when one of the main villains is about to throw the Doctor into the egg chamber to certain death you can see what appears to be a frail main on the bottom left of the image ready to catch Tom Baker as he falls.  I feel for this poor stage hand attempting to catch all 6' 3'' of Baker as he is thrown into the closet.

Most of you like to think of the derelict ship as a military vessel, transporting the alien eggs to infect an enemy, as part of some interplanetary war.

I, myself, preferred to think that the space jockey wasn't transporting the eggs, but was an innocent victim, as were our heroes. I think this because the space jockey clearly had been the victim of a chest-burster, and it seems unlikely that he would have let this happen if they were his own weapon. Also, the egg chamber is way bigger than it needs to be if it were originally intended just to hold the small eggs. Also, this way of thinking makes the universe a bit bigger; it means we still don't know where the aliens came from or who might have engineered them.

Thanks to everyone who voted!

But, from the rumors we hear about Prometheus, it seems Ridley Scott agrees with most of you guys; I think the space jockeys are gonna turn out to be not-so-friendly.

Edge of the egg chamber set for Alien. The blue lights were on loan from the The Who concert next door. The film implies the lights are a stasis field preserving the eggs. This lends credence to the idea that the space jockey was intentionally transporting the eggs, perhaps as biological warfare.
