Last week, I posted a blog entry about a recent PLOS publication discovering that fruit bat fellatio extends copulation time. Well here is the video as promised.
“Drowsiness is red alert!”- Dr. William C. Dement (he even gave me a squirt gun engraved with this public service announcement)
This is the 3rd annual Drowsy Driving Week, advocating to reduce/prevent drowsy driving at all costs. Routine 20 min naps help combat driving sleepiness. If this driving sleepiness is caused from total or partial sleep deprivation (i.e. an all nighter) then find a DD!
Over 1.9 million crashes are reported annually from drivers falling asleep at the wheel. Many have been fatal.
Newsweek has a fascinating slide show recapitulating the history of birth control. From chastity belts to Lysol douches to female condoms, human history waxes and wanes from societal endorsement of abstinence and safe sex. Advocating for the practice of safe sex has been a crucial platform of the Obama administration. This certainly was an effective tactic in The Girl Next Door when Matt and his nerdy “tripod” of friends created an educational sex video featuring porn stars. And it worked!
On a related note, boys in the 18th and 19th century were fitted with penile clamps, preventing them from masturbating or having erections at night. It essentially was a “one size fits all” cock ring with jutting barbed spikes (imagery is enough, not visual media necessary). Before the development of polysomnography and the subsequent discovery of nightly erections (nine a night!) coinciding with REM sleep, it was assumed that these nightly erections were associated with “wet dreams” and not a physiological phenonmenon called nocturnal penile tumenscence. Nocturnal penile tumenscence enables doctors to determine if erectile dysfunction is psychologically and/or physiocally mediated. It’s a more invasive measure than the “postage stamp” test. Perhaps Charlotte would had benefitted from this information…..
Last week, I mentioned that the promotional logo of the neo-A Nightmare on Elm Street was “Don’t Fall Asleep.” Last night, http://www.montegraphia.com and I watched The Haunting in Connecticut and Paranormal Activity, and again, the underlying message was : 1) Don’t Fall Asleep and/or 2) if sleep pressure is too much, Don’t Sleep Walk. Even if all three movies support America’s number one medical problem, sleep deprivation, at least Paranormal Activity showed that sleep walking coincides with deep sleep and not REM sleep, as most commonly thought; Katie’s sleep walking commenced roughly two hours after bedtime when she was most likely to be in slow, deep sleep, which dominates the first third of a 7-8 hour sleeping episode. I highly doubt that sleep consultants were hired though, given the movie’s poor, undergraduate grainy quality.
Tonight is Halloween. Kent State has one of the largest Halloween celebrations in the country. And tomorrow, we will all get an extra hour of sleep to nurse off those hangovers. It’s Daylight Savings. Daylight Savings was initiated by Benjamin Franklin to reserve candle wax.
Now back to hangovers. At yesterday’s lab meeting, the boss, Dr. D. Glass, was telling us about a recent Mythbusters episode where they dissected the common adage of “beer before liquor never been sicker” and “liquor before beer in the clear.” Apparently, the cast of Mythbusters discovered the hard way that drinking beer all night results in unbearable hangovers.
I heart science.
Today, my lab mate, Gagandeep Kaur successfully defended her dissertation: “Phase regulation of the circadian clock: neuropeptidergic and serotonergic mechanisms.” You can read about figments of her dissertation in a recently published article investigating rapid circadian re-entrainment to a new photocycle (i.e. time zone) following brief, constant light exposure and systemic administration of serotonergic agonists. The administration of serotonergic agonists (i.e. antidepressants) advances circadian rhythms by means of advancing the time of activity onset. When exposing nocturnal animals to constant conditions of light, the extent of advance of activity onset is potentiated.This type of accelerated re-entrainment would be beneficial for travel to far time-zones.
Dr. Kaur is off to work at a nearby veterinary clinic, applying her circadian experience towards better veterinary animal care.
In the week’s Journal of Neuroscience, an artistic rendition of the weekly featured article was illustrated by Greg Dunn of UPenn. GABA-ergic projectoins have been found to gate glomerulus neuronal activity, hence gating olfaction.
Another article in this week’s journal characterized the rrecruitment of motor and interneurons critical for swimming in the zebrafish, which surprisingly begins early during embryonic development. Fast and strong neurons are recruited first (I’m guessing they are large, myelinated neurons with many dendritic arborizations) followed by the weaker and slower neurons (smaller, myelinated and/or non-mylineated, unipolar and/or bipolar).
This infrared photograph is from a recent article in Nature highlighting thermoregulation in sea stars. During high tide, sea stars absorb cold water to prevent overheating.
“At present, we do not know why genital licking occurs, and we present four non-mutually exclusive hypotheses that may explain the function of fellatio in C. sphinx.”
Hey, it’s in PlosOne. Blow jobs, er, excuse, fellatio, oral sex, and/or whatever other polite term you care to use increase copulation in bats. The average licking session extends copulation by 6 seconds. Rodents also have stereotypic foreplay known as “pacing” to increase copulation. If Freud was still alive, I’m guessing he would extrapolate his “theories” and say that all mammals are fixated in the oral stage of development.
I tried finding a video of bats caught in the act, but none yet. The authors of the article can’t keep this million dollar movie footage hidden for long, I imagine.
Per ZombieLand. Clearly, this is ironic for the heroes of Zombieland to acknowledged that Americans are sleep deprived when they have brain eating, gut guzzling, blood thirsty zombies eating all the humans in the world. But, nice of Wichita to address America’s ongoing epidemic.
I can’t vouch, however, for the movie trailer of A Nightmare on Elm Street preceding the showing of Zombieland. It urges people not to sleep, particularly kids, or expect to not ever awake.
