Shouldering: Penis Extraction in Rove Beetles
by Kelsey in Mauka to Makai
I don’t “have a thing” for critters with remarkable genitalia. (I swear.) But, while researching barnacle sex, I came across a paper about a male beetle with an intromittant organ (penis) so long and flexible that he has to sling it over his shoulder to keep it safe. Clearly, I couldn’t keep such information to [...]... Read more »

Barnacle Sex
by Kelsey in Mauka to Makai
Sad but true: Barnacles (critters who spend the majority of their lives with their heads glued to a hard surface) may be getting more action than you are.
Of course, that depends on how you quantify “action.” Barnacles have a fairly short mating season—compared to our non-stop mating season—but they cram a whole lotta nooky into [...]... Read more »

Altruism-On-Demand: I’ll help, but only if you ask nicely…
by Kelsey in Mauka to Makai
On Thursday, scientists rescued a dog from the icy waters of the Baltic Sea…In December, a Portland, Maine “secret Santa” gave 100 strangers $100 apiece…And, so far, Americans have donated $29 million to American Red Cross Haiti relief efforts.
Humans are so darn nice. But how exactly did that happen? That’s what scientists at the Primate [...]... Read more »

Climate Change May Make Fish Commit Predator-Assisted Suicide
by Kelsey in Mauka to Makai
Remember the tale of Nemo (the juvenile clownfish that was fish-napped by a dentist) and Marlin (Nemo’s dad)? Marlin braves the open ocean to find Nemo, meeting a whale-speaking blue tang and a few non-piscivorous sharks along the way. Of course, Marlin and Nemo are reunited (it’s a Disney movie), but could a little clownfish [...]... Read more »

Marine Mucilage, Ick!
by Kelsey in Mauka to Makai
What’s grosser than gross? How ‘bout a 100-mile long wad of E. Coli-infested mucus?
(Oh, sorry, did that make you gag? We said it was grosser than gross…)
Mucus wads—also known as mucilages—have been reported in the Mediterranean Sea since at least 1729, but recent research found that the loogies are getting bigger, lasting longer and harboring [...]... Read more »

Sperm Wars
by Kelsey in Mauka to Makai
It may be a dog-eat-dog world* out there, but nowhere is the competition fiercer than in the female reproductive tract.
Biologically speaking, the goal of every male is to produce as many offspring as possible. To do this, males need to have some kick-ass sperm, but according to a recent study, too much kick-ass sperm can [...]... Read more »

Fueling the Future…With Urine and Chicken Remnants
by Kelsey in Mauka to Makai
The moment you’ve all been waiting for is finally here! Scientists have discovered a way to make something we need (fuel) from a readily accessible, unlimited resource (pee) and a fairly abundant, otherwise useless resource (chicken feather meal).
Why do we need new sources of fuel? Ummm, because…
Oil is old school.
Coal is dirty.
Algae is promising, but [...]... Read more »

It’s Not Just Penguins…
by Kelsey in Mauka to Makai
Just like Brangelina, gay penguins always make the headlines. Years ago, Roy and Silo—two male chinstrap penguins at the Central Park Zoo—tried to incubate a rock. It never hatched. Zookeepers then gave the pair an abandoned egg, which they successfully incubated and raised to be a healthy chick.
In 2008, a wily pair of penguins at [...]... Read more »
