Hormones not the only drivers of sex disparities in heart health
Often when it comes to disease, the sexes are not equal. Dementia, chronic kidney disease, and many other conditions disproportionately affect one sex or another. Heart disease is a complex case: Males are more likely to suffer heart attacks at … Continue reading

Is scientific progress waning? Too many new papers may mean novel ideas rarely rack up citations
There are so many papers coming out in the largest fields of science that new ideas can’t get a foothold, according to a recent study in PNAS. Researchers analyzed citation trends for 90 million papers and found that in very … Continue reading

To find zoonotic viruses, researchers seek genomic signatures of virus adaptations to hosts
In light of the ongoing pandemic, researchers have stepped up efforts to identify new zoonotic threats—viruses that could make the leap from animals to humans and cause future epidemics. Studies aiming to identify such viruses often focus on a novel … Continue reading

Using helpers, desert birds hedge their bets to weather variable conditions
Unpredictable environments can help explain the evolution of cooperative behavior, according to a decade-long study of birds in the Kalahari Desert. The research showed that white-browed sparrow-weavers (Plocepasser mahali) work to raise the offspring of other birds as a strategy … Continue reading

Frustrations can combust into a riot regardless of age, politics, or gender
The most common caricature of riots suggests criminal young men are the culprits. But a recent study in Proceedings of the Royal Society B suggests that is not necessarily the case. The study used a video game to incite virtual … Continue reading
An algorithm suggests a sidewalk-space redesign to make cities safer for pedestrians
A recent study in Communications Physics is among the first to systematically analyze whole city networks of spider-webbing roads and sidewalks. Examining 10 global cities, including Boston, Paris, and New York, researchers created an algorithm that could help planners choose … Continue reading

Digital reconstruction gets to the root of 400-million-year-old plant
Researchers have managed to reconstruct the detailed 3-D structure of a fossilized plant more than 400 million years old. The ancient leafy organism, a relative of today’s clubmosses, grew in the Early Devonian era—a crucial time for the development of … Continue reading

Robot swarms communicate best when messages spread neighbor to neighbor
In the not-so-distant future, swarms of robots could help contain environmental disasters such as wildfires, by locating and dousing the most dangerous patches, even as flames move and spread. But how would these individual robots coordinate effectively to pull off … Continue reading
