How much heat can the body withstand?
In 1948 Dr. Craig Taylor at the University of California at Los Angeles created a heat chamber to determine the human tolerance for extreme heat. He experimented on himself. In the picture (from the Life archive) you can see him sitting in his hotbox, heated to a pleasant 220° fahrenheit. The egg on the metal pan in front of him was frying. The highest temperature he ever endured was 262°.There was a practical point to this. He was trying to determine the maximum heat a fighter pilot could withstand, should the refrigeration system in their plane fail.
For more info about Dr. Taylor's heat experiments, check out the old article from Popular Science posted on the Modern Mechanix blog.

The Mechanics of Stabbing
In a paper recently submitted to arXiv.org, researchers describe an attempt to determine the exact amount of force required to stab someone. No, they didn't stab real people. They stabbed synthetic materials such as polyurethane, foam, and ballistic soap. But oddly, no one had previously determined the exact amount of force needed for stabbing. Forensic scientists had simply used qualitative terms such as "mild force" or "severe force".Some of their findings: 1) The best household knife to stab someone with is a utility knife:
Four different commonly available household knives (cook’s, utility, carving and kitchen knives) were tested. The utility knife required the least amount of force or energy to penetrate the skin and was associated with the smallest amount of out of plane skin displacement, while the cook’s knife required the greatest force, energy and out of plane displacement.
2) However, not all knives are created equal. Even two identical knives by the same manufacturer can vary greatly in sharpness and ability to penetrate skin:
Evidence suggests that the quality control processes used to manufacture knives fail to produce consistently uniform blade points in nominally identical knives, leading to penetration forces which can vary widely...
the penetration forces associated with nominally identical knives, even virgin knives, can vary by as much as 100%.

Bernie Krause
The musician Bernie Krause has had an arguably weird and fascinating career. He's gone from being a minor pop star to being a scientist in the field of bio-acoustics, or the noises of the natural world. Along the way he came up with the concept of "biophony," short for the biological symphony that each ecosystem makes.The first clip below shows him at work, while the second is a trailer for his concepts.

LIFE Photo Archive
Google recently announced it's struck a deal to host the entire photo archive of Life magazine. Millions of photos (including many previously unpublished ones) will be made freely searchable online. If you're the kind of person who likes to browse through archives searching for weird stuff, it's pretty much a goldmine.Only about 20% of the archive is online so far, but I've already had fun browsing through it. Below are a few photos I found doing a search for bird experiments.
The LIFE captions are pretty dry. I thought they could be improved by coming up with new captions in the style of LOL Birds. I'm sure the WU readers can come up with better captions than I was able to.
LIFE caption: Visual perception experiment on chickens, showing chick wearing a rubber helmet with prisms in the eyepieces, 1953.
My caption: "Mommy told me to wear my safety helmet!"

Shrimp on a Treadmill
Scientific researchers placed a shrimp on a shrimp-size treadmill in order to measure its speed and endurance. This information, they say, "will give us a better idea of how marine animals can perform in their native habitat when faced with increasing pathogens and immunological challenges." Luckily for us, they videotaped the experiment.The video has become hugely popular on the internet, spawning numerous remixes. For instance, witness Shrimp Jamming to Muzak:
There are so many of these remixes you could probably spend an entire day watching them.

Fonzarelli Syndrome
A 77-year-old man presented with a 1-year history of upper limb rest tremor, rigidity, and bradykinesia. He reported focal dystonia affecting the right thumb over the preceding 7 years, resulting in a constant "thumbs up" gesture reminiscent of the fictional television character Arthur Fonzarelli. Subsequent levodopa therapy reduced his bradykinesia and rigidity, but did not ameliorate the dystonia.
While foot dystonia is a common feature in late Parkinson disease (PD), dystonia may precede the development of PD by several years. Writer's cramp has been described as an early manifestation, with extension of the great toe also noted (the striatal foot).

Guess the Scientist, #3
What famous sixteenth-century scientist does this passage describe? Answer is in extended (and in the comments)._________ relates in one of his autobiographies (he wrote three) that he was completely impotent from the age of twenty-one until his marriage at the age of thirty-one; but that after he wed, the union resulted in three children, two boys and a girl...
_________ also suffered from an amazing array of physical problems and ailments, including: stuttering; chronic hoarseness; nasal discharge; heart palpitations; hemorrhoids; indigestion; malaria; gout; chronic itching; hernia; colic; insomnia; dysentery; and a malignant growth on his left nipple. He also had some truly odd physical problems. He wrote that "in 1536 I was overtaken with an extraordinary discharge of urine; and although for nearly forty years I have been afflicted with this trouble, giving from sixty to a hundred ounces a day, I live well."

Bjork and Her Television
I really think the beloved and utterly unique Bjork should be the official spokesgal for WEIRD UNIVERSE.

Guess the Scientist, #2
What scientist wrote the following passage? The answer is in extended (and on the comments page).A small experimental room was fitted with a bed and other items conducive to a normal sexual response. The bed was placed directly against a wall through which an opening was made. Both sides of the opening were covered with a thick sheet of foam rubber. Slits were made in the foam rubber so that the leads to the instruments could be passed to the recording room while still maintaining the privacy of the experimental room. All of the subjects were married and were between the ages of 22 and 30.
To record the heart rate four electrocardiographic leads, fashioned from wire mesh attached to an elastic bandage, were fastened to the upper thighs and the upper arms. With this technique the ECG was readable even during the periods of greatest muscular activity. During foreplay, records were taken each minute on two Sanborn direct writing electrocardiographs. During coitus continuous recordings were made, and after withdrawal records were again made a 1-minute intervals. Three tests were performed on each of three couples.
