In response to massive battlefield setbacks, Russia has increased its attacks in Ukraine on everything from power plants and dams to railways, pipelines and ports. These attacks against civilian infrastructure are not random. Rather, they reflect an insidious calculus integral to modern Russian military theory. For more than 20 years, Russian military journals have emphasized...
A new study from the Wildlife Conservation Society (WCS), Colorado State University, and the National Park Service indicates previously unknown high altitude contests between two of America’s most sensational mammals – mountain goats and bighorn sheep – over access to minerals previously unavailable due to the past presence of glaciers which, now, are vanishing due...
Psychedelic compounds found in ‘magic mushrooms’ are increasingly being recognised for their potential to treat health conditions such as depression, anxiety, compulsive disorders and addiction. However, very little is known about how such compounds have evolved and what role they play in the natural world. To address that, scientists from the University of Plymouth...
If Russia’s invasion and the ensuing war significantly reduce Ukrainian grain exports, surging prices could increase food insecurity and carbon dioxide emissions, as marginal land is pushed into crop production. That’s the chain reaction predicted by modeling from a research team that includes Amani Elobeid, a teaching professor of economics at Iowa State University. An...
Watch any episode of “CSI,” and a character will use forensic DNA profiling to identify a criminal. A new study from San Francisco State University suggests that these forensic profiles may indirectly reveal medical information — perhaps even those of crime victims — contrary to what the legal field has believed for nearly 30 years. The findings...
Key Takeaways: Consumers reduced purchases of breakfast cereals with the new warning labels for unhealthy foods. The chocolate and cookie categories did not demonstrate the same impact.

Menthol use has increased over the past decade among U.S. adults who smoke cigarettes, according to a study released by Columbia University Mailman School of Public Health and The City University of New York. Menthol use is much more common among adult smokers who are younger, from racial/ethnic minoritized groups and with mental health problems....
An odor machine, so-called olfactometer, makes it possible to smell in VR environments. First up is a “wine tasting game” where the user smells wine in a virtual wine cellar and gets points if the guess on aromas in each wine is correct. The new technology that can be printed on 3D printers has been...
People often visit U.S. national parks to catch a glimpse of wildlife. But how does our presence impact the animals we hope to see? National park traffic has grown steadily over the past decade, and popular parks like Yosemite and Yellowstone can easily see over a million visitors a year. In these heavily used areas,...
“Women are better. The female advantage is consistent across time and life span, but it is also relatively small”, says Marco Hirnstein, professor at The University of Bergen, Norway. Hirnstein is interested in how biological, psychological, and social factors contribute to sex/gender differences in cognitive abilities and what the underlying brain mechanisms are. Will the...
