The Perfect Gift This Holiday Season: The Neanderthal Test

If you’ve ever wondered if your slothful spouse—he of the prominent brow and grunted endearments—has caveman blood, wonder no more. Genomics company 23andMe, purveyors of fine genotyping, would like to suggest a gift that will keep on giving this holiday season: the Neanderthal test, which will give you nagging rights for eternity.

The latest gossip says the Neanderthals, the other human species kicking around about 30,000 years ago, did not leave this earth without spreading a few wild oats among our Cro-Magnon ancestors (nudge nudge, wink wink). And genetics, as so many daytime talkshow guests can tell you, is where such secrets go to die. Everyone except Africans (who missed the shackin’ up party that was prehistoric Europe) now has a sort of genetic souvenir, a remnant of our forebears. (more…)

Finally! The Ostrich Penis Provides the Answer to a Long-Standing Question

Penises, as a general rule, are some of the more improbable structures in biology (especially bird penises). There are many ways in which they are marvels of engineering—and prime examples of the truly weird avenues evolution will explore, as long as more babies result. One major miracle is that they manage to stand up, something achieved, in most penises you’re likely to be familiar with, with a huge rush of blood. But bird penises (of course! showoffs) have taken another route. They stand up with lymph instead.

Dizzy Discus Throwers, Horny Beer-Bottle Beetles, and the Wasabi Alarm Clock: the 2011 Ig Nobels

Those classy folks at the Annals of Improbable Research are at it again. Last night, they announced the 2011 winners of some of the most coveted awards in science: the Ig Nobels.

You should watch last night’s ceremony in its entirety, but here are (drumroll) the winners:

  • First off, in Physiology…from the Cold-Blooded Cognition Lab at the University of Vienna, Anna Wilkinson, Natalie Sebanz, Isabella Mandle, and Ludwig Huber for their paper No Evidence of Contagious Yawning in the Red-Footed Tortoise, published this year in Current Zoology. As it turns out, if one tortoise is yawning, its buddies won’t join in. Not even if you show them movies of yawning tortoises.
  • In Chemistry…Makoto Imai, Naoki Urushihata, Hideki Tanemura, Yukinobu Tajima, Hideaki Goto, Koichiro Mizoguchi and Junichi Murakami for determining what concentration of airborne wasabi can awaken sleeping people in case of emergency. They are the inventors of the wasabi alarm, described in US patent application 2010/0308995 A1.
  • In Medicine…Mirjam Tuk, Debra Trampe and Luk Warlop, and Matthew Lewis, Peter Snyder and Robert Feldman, Robert Pietrzak, David Darby, and Paul Maruff for illuminating how an intense need to pee can affect your decision-making capabilities in their papers Inhibitory Spillover: Increased Urination Urgency Facilitates Impulse Control in Unrelated Domains and The Effect of Acute Increase in Urge to Void on Cognitive Function in Healthy Adults.

150 Kids, Anyone? US Sperm Banks Overdoing It

Sperm banks are a pretty great idea: women who don’t have a male partner or whose partners aren’t fertile can choose a genetic father with characteristics they like, such as a certain height, eye color, hair color, hobbies, and so on. Thousands of children are born each year in the United States to mothers who like the sound of “tall, dark, enjoys astrophysics and Shostakovich” or “blond surfer, Ivy-League educated, great sense of humor.”

But something very strange has been going on over the last couple decades, and the New York Times covers it in a recent piece: some donors’ sperm has been used many, many times—so many times, in fact, that people are starting to get alarmed.

German Prostitutes Pay Streetwalking Fee at Parking Meter-Like Machine

parking
Get yer streetwalking permit here!

From 8:15 pm to 6:00 am each day, prostitution is legal in Germany, where working call girls staff brothels, sauna clubs, and other such establishments. In the city of Bonn, which, uh, “boasts” around 200 prostitutes, an average of 20 freelancers go cruising each night, picking up clients on the street and heading to garage-like structures called “consummation areas” the city put up especially for that purpose. They’ve thought of everything, those Germans!

Girls in the various brothel-like establishments have always been subject to a prostitution tax, but streetwalkers, apparently, haven’t being paying. Now, though, the city has a way to make things fair for everyone: a parking meter for prostitutes.

Kinky Skinks Show That Size Matters in Speciation

skinks

When a male’s bits don’t fit with a female’s bits, you wind up with reproductive malfunction. But shape isn’t everything, as a team of researchers recently discovered while watching hundreds of skink lizards court and spark.

Most studies looking at how genitalia mismatch contributes to new species take the concept literally: if the bits don’t fit together like lock and key, matings will be unsuccessful. And if the mismatch between the gear of two groups is bad enough, they will form separate reproductive populations, and, eventually, species. But the idea, which was first tossed around more than 150 years ago, has been discounted as a possible source of new species. Differently sized or shaped genitalia is such a big change that it’s likely to come after many other speciation triggers, like mutations or long separations between populations divided by mountain ranges.

Bad News for Roosters: If You Aren’t King of the Henhouse, Your Ejaculate Will Be Ejected

rooster
WHAT? Noooooooo!

If you haven’t heard about the corkscrew kookiness that is duck genitalia by now, you need to check that stuff out ASAP.

Ducks’ twisting vaginas and telescoping penises are well-known part of an evolutionary arms race between the sexes that’s been going on for millennia, with each side trying to exert control over which males’ sperm fertilize the female’s eggs—a battle that, especially in birds, is fierce, occasionally violent, and weird as all-get-out. The most recently discovered example of what biologists deem “sexual conflict,” a little behavior hens have developed called sperm ejection, upholds that fine tradition.

What Caused the Recent Explosion in the Number of Bisexual Men?

spacing is important

By now you’ve probably heard the recent news that male bisexuality is in fact real, in stark contrast with a 2005 study by some of the same scientists that claimed just the opposite. Bloggers and news outlets have unleashed a torrent of witty headlines and snarky remarks about the research, such as CBSNews’ “Study says bisexuality real, but bisexuals say ‘duh.’” Even the Gray Lady herself, The New York Times, got in on the fun with its quip, “No Surprise for Bisexual Men: Report Indicates They Exist.”

Presumably the studies aren’t picking up on a real increase in bisexuality over the past six years, so what’s the deal here—why the sudden change of heart for the Northwestern University researchers?

Showy Male Birds—You Live Life Like a Candle in the Wind

spacing is important

For male Houbara bustards, extravagant sexual displays come with a price: rapid sexual aging. By studying over 1,700 North African Houbara bustards, researchers in France have learned that the birds, by age six, already begin producing smaller ejaculates with a large number of dead and abnormal sperm. The more showy the bustard, the quicker he burns himself out. As lead researcher Brian Preston said in a prepared statement:

This is the bird equivalent of the posers who strut their stuff in bars and nightclubs every weekend. If the bustard is anything to go by, these same guys will be reaching for their toupees sooner than they’d like.

Male Black Widow Spiders Try to Avoid Sex That Will Kill Them

spacing is important

Sometimes sex just isn’t worth your life.

For male black widow spiders, standing at just a quarter of the size of their mates, sex involves a very real danger: females of the species have no qualms about turning cannibalistic if they’re hungry after getting down and dirty. But it seems that it’s more than just a game of chance for horny male spiders. Researchers at Arizona State University have now learned that simply walking on the webs of female spiders can provide males with chemical cues telling them if their potential mates are ravenous enough to eat them.
