The duplication crisis might likewise be a theory crisis

The duplication crisis might likewise be a theory crisis

Enlarge / A jumbled jigsaw puzzle, AKA the state of theory in the behavioral sciences. A replication crisis has called into question results from behavioral (and other) sciences. Complaints have focused on poor statistical methods, the burying of negative results, and other “questionable research practices” that undermine the quality of individual studies. But methods are…

Brand-new price quote of primate anomaly rates assists genes match fossils

Carl, an alpha-male chimpanzee at Copenhagen Zoo and one of the participants in the study. Copenhagen Zoo, David Tr It’s not every day that scientists accidentally uncover a gorilla paternity scandal. But when a team of researchers led by Søren Besenbacher in Denmark went looking for genetic data on great ape families, one of their…

Spotify information demonstrates how music choices alter with latitude

In Anchorage, Alaska, in the bleakest midwinter, the Sun rises just after 10am, hovers close to the horizon for a few hours, and dips back down again shortly before 4pm—all in all, just five hours and 28 minutes of daylight. Around that winter solstice (just in time for Christmas), Spotify listeners in the most northerly…

Enlarge / An adult male hermit crab of the species Coenobita compressus ambling along on a leisurely stroll. Hermit crabs protect their soft, curved abdomens from harm by scavenging seashells and turning them into portable homes. That poses a challenge when it comes time to mate, since a rival can steal the shell while its…

Courtesy of University of Wisconsin, Madison. The homely hagfish might look like just your average bottom feeder, but it has a secret weapon: it can unleash a full liter of sticky slime in less than one second. That slime can clog the gills of a predatory shark, for instance, suffocating it. Scientists are unsure just…

Political radicals do not assess their own mistakes– about anything

What makes some people radical and prone to taking extreme views on topics? Radical, violent political movements have received a lot of attention in the news cycle, while non-violent radicalism is a significant impediment to the compromises that are necessary to build a functional society. At the same time some things we now take as…

Soy milk, almond milk, oat milk. Spider milk?

Enlarge / The spider in question, without its young. Milk comes from mammals. It’s kind of a distinctly mammalian thing. Even our government knows that. And yet, Chinese scientists have documented jumping spiders that provide their young with droplets of a nutrient-rich fluid from a furrow on the mother’s body. It is the sole nourishment…

Big hereditary research study discovers very first genes gotten in touch...

If you have ADHD, chances are higher that your siblings do, too. Estimates differ as to how strong the connection is, but the arrows point in the same direction: genetics helps determine someone's risk for ADHD. Beyond that, we still have myriad questions and not many answers—which genes play a role? And how do those…
