Ever wondered how to spot if something's off with the hidden traits in your data? Researchers have come up with a neat way to do just that. They've created what they call the "generalized Hausman test. " This isn't your average test; it's designed specifically for those tricky unidimensional latent
In December 2022, scientists in Botswana found a new sublineage of the Omicron variant of COVID-19, called FN. 1. This variant was discovered in samples from a few places in the Greater Gaborone district. To understand more about this new variant, researchers looked at its spread around the world an
Ever wondered why some bird moms have more boys or girls? It all comes down to their quality and the environment. Carolina wrens, which are loyal to one mate, face this dilemma. If a mom is in good shape, she might have bigger sons who can fight for food. But if she's really high-quality, she might

Scientists are exploring a new way to keep an eye on nuclear reactors. They want to use special towers called eddy covariance towers to detect heat released by reactors. These towers are often used to study how ecosystems exchange heat and water vapor. The idea is to see if we can tell when a reacto
Have you ever wondered how athletes manage their training when things get super intense? This study dives into that question, focusing on swimmers. They wanted to see if a fancy algorithm, called the variable dose-response model, could help track when swimmers push too hard and start to feel really
In long-term studies where researchers are examining events that happen over time, it's common to find that important factors, or covariates, change over time. The old-school Cox regression model can deal with these changing factors but assumes that their impact on the likelihood of an event is just
Celery, a key player in the vegetable world, has many forms.
