SCIENCE CORNER ’09: Hey, Space Brother

Paleontologists claim they have unearthed a new type of pterosaur and a previously unknown sauropod dinosaur in the Sahara Desert.
The banana slug, beloved mascot of UC Santa Cruz, has a weird mating habit. First of all, they have an enormous penis. (In fact, their latin name dolichyphallus translates to “giant penis.”) The average size of a banana slug penis is 6 to 8 inches. This is incredibly impressive, considering their entire body length is 6 to 8 inches as well! Banana slugs are hermaphrodites, so two slugs will try to fertilize each other.
To mate properly, a slug must choose a mate roughly its own size – if it miscalculates, its penis will get stuck during copulation. This isn’t just an embarrassing faux pas, the other slug will actually bite off the stuck penis, a term scientists euphemistically called “apophallation.”

Some of the chemical pathways for physical pain and pain from social exclusion overlap. The physical pain system may have been co-opted to motivate social animals to respond to threats to their inclusion in the group. The physical-social pain overlap helps to explain the paradox that people who are threatened with social exclusion sometimes react with physical violence.
All octopuses are venomous but only a few species pose a significant threat to humans, such as octopuses in the genus Hapalochlaena which have a very poisonous bite.
A few of the larger tropical cone snail species have a very poisonous sting. These bites and stings can sometimes be fatal.
Ouroboros researches aging.
Identical twins tend to die within 3 years of each other, whereas fraternal twins tend to die within 6 years. Aging theories associated with DNA include programmed aging (or programmed aging-resistance) and theories that link aging with DNA damage/mutation or DNA repair capability.
