The authors’ model, named pathway multinomial logit or “pathway MNL,” does not reveal causal effects, they caution, but the associations they uncover are informative for museum professionals. Multimedia guide users largely visited recommended artworks in the suggested order. Lisa van den Bos, product manager for digital education at the museum while the study was underway, ..

Here, its solution is grand in scope. It views the maker community, which is mostly interested in scratching personal itches, as a sign that the US public wants to make things again. The SNGA authors figure that they would be perfectly happy making things for science. “Establish national fellowships for skilled craftspeople,” they suggest, “practitioner-in-residence ..
Credit: Kathryn Ayres Credit: Kathryn Ayres There have been numerous accounts in recent years of orcas ramming boats—and sometimes sinking them. Scientists believe this may be a form of culturally learned behavior passed down through generations. Now we have fresh examples: orcas in the Gulf of California were filmed teaming up to ram sunfish with ..
A photon is a single particle of light, and under normal circumstances, it can’t be divided. But a photon is also not a particle, in the sense that it does not have a specific location. Instead, it is an extended object. So if a photon is only partway through the process of reflecting from a ..
When Mount Vesuvius erupted in 79 CE, it spewed molten rock, pumice, and hot ash over the cities of Pompeii and Herculaneum, killing thousands of people. It’s one of the most famous natural disasters in human history, so naturally there have been countless documentaries about Pompeii (and at least one popular song). But only one ..

Monitoring programs are typically labor-intensive and expensive, requiring teams to set and check traps, alongside specialists who can identify, sort, and test the samples. While some traps attract female mosquitoes with “stinky water” loaded with decaying organic material, others require dry ice to release carbon dioxide that mosquitoes sniff out when hunting for mammals. But ..
It’s a complicated story, so it’s worth recapping what’s occurred so far, followed by the most relevant details from the newly published articles. The New Orleans Five controversy The five ousted scientists were Steven Kahn, professor of medicine at the University of Washington, who is the editor-in-chief of Diabetes Care and a co-author of the ..
These approaches are still the subject of ongoing development, so the report has two recommendations: researchers should be very transparent about the uncertainties in what they’re doing, and they should develop tools to make these analyses useful for disaster preparedness. Knowing that a new weather extreme is possible is far less useful than knowing what ..
