Every Friday at Nothing in Biology Makes Sense! our contributors pass around links to new scientific results, or science-y news, or videos of adorable wildlife, that they’re most likely to bring up while waiting in line for a latte.
From Noah: Paleontologists reconstruct the song of a fossilized Jurassic-era katydid.
Examining the insect’s seven centimeter long fossil wings under microscope, researchers were able to see how the prehistoric male katydid employed stridulation, i.e. rubbing body parts together, to produce a song to attract a female.
From Jon: A tranquilizer that is commonly abused as a club drug shows great promise for treating depression.
And the patient, they say, you know, yeah, it helped with my pain, but, you know, my depression seemed better. And so this was sort of a curiosity for a long time until a few years ago, when some folks at the National Institutes of Health decided that they really wanted to check this out.
From Sarah: The New York Times on the natural history of venomous mammals.
Every so often, however, a mammalian lineage discovers the wonders of chemistry, of nature’s burbling beakers and tubes. And somewhere in the distance a mad cackle sounds.
Skunks and zorilles mimic the sulfurous, anoxic stink of a swamp. The male duck-billed platypus infuses its heel spurs with a cobralike poison. The hedgehog declares: Don’t quite get the point of my spines? Allow me to sharpen their sting with a daub of venom I just chewed off the back of a Bufo toad.
From Jeremy: Antibiotic-resistant strains are now so widespread that we may soon see the day when gonorrhea is untreatable.
Gonorrhea is one of the most common sexually transmitted diseases in the world—with about 600,000 cases diagnosed in the U.S. each year. A few years ago, investigators started seeing cases of infection that did not easily respond to treatment with a group of drugs called cephalosporins, which are currently the last line of defense against this particular infection. Now, the number of drug-resistant cases has grown so much in the U.S. and elsewhere that gonorrheal infection may soon become untreatable, according to doctors writing in the February 9 issue of the New England Journal of Medicine.
