(Press-News.org) In research published in Insect Conservation and Diversity, investigators analyzed records from social media to explore which arthropods—including insects and spiders—are most preyed upon by domestic cats in urban environments.
The scientists, who conduct their research at the University of Campinas, in Brazil, searched TikTok and iStock, analyzing more than 17,000 photos and videos, which yielded 550 records of predation events by domestic cats.
In total, they recorded 14 distinct arthropod orders killed by domestic cats. Orthoptera (which includes grasshoppers, locusts, and crickets) was the most frequently preyed upon order, accounting for 20.7% of records. Hemiptera (which includes more than 80,000 species of “true bugs”) and Blattodea (which includes cockroaches and termites) were also commonly observed (14.5% and 14.4%, respectively).
The findings reveal that domestic cats hunt a surprisingly diverse range of arthropods in urban settings. The data collected from social media showed similarities but also some differences compared with general patterns reported in the scientific literature.
“The most exciting aspect of our research is that we were able to use social media data to reveal an impact of domestic cats on biodiversity that has been relatively overlooked by the scientific literature," said Leticia Alexandre, lead author and undergraduate student at the University of Campinas. “Indeed, our results document cases of cats attacking groups of arthropods that have never been identified in academic papers as cats’ prey,” added co-author Raul Costa-Pereira, PhD. “Therefore, social media platforms can offer much more than cute photos and videos of cats, aiding in understanding and reducing their effects on biodiversity.”

All-you-can-eat: Young adults and ultra-processed foods
2025-11-19
Young Americans are gaining weight.
An analysis published in The Lancet predicts that one in three Americans age 15 to 24 will meet the criteria for obesity by 2050, putting their health at risk.
While genetics, inactivity, and many other factors are at play, diet features prominently.
Ultra-processed foods — which make up 55 to 65 percent of what young adults eat in the U.S. — have been associated with metabolic syndrome, poor cardiovascular health, and other conditions in adolescents.
Researchers at Virginia Tech wanted to investigate the effects on 18- to 25-year-olds of a diet high in ultra-processed food and a diet without ...

AMI warns that the threat of antimicrobial resistance in viruses and other pathogens cannot be underestimated
2025-11-19
In World Antimicrobial Resistance Awareness Week (WAAW), Applied Microbiology International (AMI) has urged global policymakers to strengthen the revised Global Action Plan on Antimicrobial Resistance (GAP-AMR), calling for a more inclusive, clear and equitable approach to tackling one of the world’s most urgent health challenges.
The learned society warned that the updated GAP-AMR must go beyond bacterial and fungal pathogens to include all AMR-causing organisms, such as parasitic and viral pathogens.
In its submission to the AMR Multi-Stakeholder Partnership Platform (MSPP) consultation, AMI brought together 15 microbiologists from ...
As ‘California sober’ catches on, study suggests cannabis use reduces short-term alcohol consumption
2025-11-19
PROVIDENCE, R.I. [Brown University] — The “California sober” trend, which involves ditching alcohol in favor of cannabis, is gaining momentum, spreading from Hollywood to health influencers to homes across America. Among the motivations for many adopters is to reduce alcohol use, and a new study on the causal effect of cannabis on alcohol consumption suggests that smoking marijuana may lead people to drink less — in the short term.
Published in the American Journal of Psychiatry, the study by researchers at Brown University is the first randomized, placebo-controlled trial to test whether cannabis use directly changes alcohol consumption. ...
Working with local communities to manage green spaces could help biodiversity crisis, new study finds
2025-11-19
Helping communities manage green spaces by understanding how they use and value the area could be an effective way for local governments to tackle the biodiversity crisis, according to a new study from the University of Exeter.
Local councils in the UK are under growing pressure to increase publicly accessible green spaces in towns and cities to boost biodiversity, as well as improve public wellbeing. Research has shown effective stewardship of urban green spaces not only improves biodiversity, but also reduces flooding, promotes public health, and creates business opportunities.
The study, published in People and Nature, outlines ...
Parental monitoring is linked to fewer teen conduct problems despite genetic risk
2025-11-19
Parents may have more influence than they realize when it comes to shaping their children’s behavior, especially for those at higher genetic risk for conduct problems, according to Rutgers Health-led research.
The study, published in Frontiers in Child and Adolescent Psychiatry, found that consistent parental monitoring – meaning knowing where children are, who they’re with, and what they’re doing – can help offset genetic risk for developing behavior problems during adolescence.
Conduct problems, which include aggression, antisocial behavior and rule-breaking, often begin in childhood and are among the most common ...

2025-11-19
Osaka, Japan — Physicists at The University of Osaka have unveiled a breakthrough theoretical framework that uncovers the hidden physical rule behind one of the most powerful compression methods in laser fusion science — the stacked-shock implosion. While multi-shock ignition has recently proven its effectiveness in major laser facilities worldwide, this new study identifies the underlying law that governs such implosions, expressed in an elegant and compact analytic form.

Can AI help us predict earthquakes?
2025-11-19
Kyoto, Japan -- Predicting earthquakes has long been an unattainable fantasy. Factors like odd animal behaviors that have historically been thought to forebode earthquakes are not supported by empirical evidence. As these factors often occur independently of earthquakes and vice versa, seismologists believe that earthquakes occur with little or no warning. At least, that's how it appears from the surface.
Earthquake-generating zones lie deep within the Earth's crust and thus cannot be directly observed, but scientists have long proposed that faults may undergo a precursory phase before an earthquake during which micro-fracturing and slow slip occur. ...
