Imagine giving birth to a baby and not being able to tell for weeks whether it's a boy or a girl. That's pretty much how life rolls for pandas — a species that, we've pointed out here before, are already saddled with incredibly complicated sex lives.
On Friday, there was a baby panda born at the Smithsonian National Zoo in Washington D.C., but we don't yet know what sex the cub is. That's because male panda genitalia — both the penis and testicles — doesn't descend until after birth. It could take weeks, or months, before you can tell the cub's sex, just by looking. In the meantime, zoo staff have taken a DNA sample that will reveal the secret in 2-3 weeks.
What's particularly interesting about this, though, is that the tendency to look sort of mannequin-y at birth isn't all that rare among bear species. The sloth bears and spectacled bears have the same issue. Meanwhile, it can be hard to determine the sex of even full-grown polar bears, because their penis is retractable and their genital region (on both sexes) is so furry. Presumably, the bears have an easier time with this question than humans do.
Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
