Animal behavior: Dogs pawsitively hooked on toys

2025-10-09
(Press-News.org) Some dogs show behaviours towards their toys that resemble behavioural addictions in humans, such as gambling and internet gaming, according to a study of 105 dogs published in Scientific Reports. 

Behavioural addictions in humans are characterised by compulsive engagement with activities despite negative consequences. Although anecdotal evidence has previously suggested that some dogs display addictive-like behaviours towards toys — for example whining when a toy is out of reach and continuing to play despite overexertion or injury — this study represents the first published scientific evaluation of such behaviours in dogs. 

Stefanie Riemer, Alja Mazzini and colleagues identified common symptoms of behavioural addictions in humans from previously published research, such as experiencing cravings and having difficulty stopping or controlling a behaviour. They then compared these with behaviours exhibited by 56 male and 49 female dogs — who were all described by their owners as motivated to play with toys — towards a toy selected by themselves at the start of the test. The dogs ranged in age from 12 months to ten years old and the most common breeds were Malinois (18 dogs), Border Collies (9 dogs), and Labrador Retrievers (9 dogs). The authors also surveyed owners about their dogs’ everyday behaviours towards toys. 

The researchers report that 33 dogs exhibited addictive-like behaviours. These included being excessively fixated on their toy, showing a lack of interest in alternatives to their toy such as food or playing with their owner, making persistent efforts to access their toy when it was unavailable, and being unable to calm down for 15 minutes after all toys were removed. When their toy was inaccessible, these dogs tended to spend longer focusing on, and trying to access it, and to prioritise accessing it over consuming food or interacting with their owner. 

The authors note that further research is needed to determine the reasons for dogs excessively engaging with toys and whether this can negatively impact their welfare.

Parasite paparazzi take millions of photos of secret malaria proteins

2025-10-09
Using millions of microscope images magnified up to 130,000 times, researchers from Radboud university medical center and Toronto have unraveled the structure of two key proteins in the malaria parasite. With this knowledge, scientists are developing new vaccines that block the transmission of parasites via mosquitoes. Malaria, a parasitic infectious disease, has existed since the time of the ancient Egyptians and still threatens nearly half of the world’s population. In recent years, two malaria vaccines have become available that protect against infection, but they ...

Lung cancer incidence after September 11, 2001, among World Trade Center responders

2025-10-09
About The Study: The results of this study of World Trade Center (WTC) responders suggests that, when compared with the lowest reported exposure levels, a higher level of reported exposure to more particulate dust or debris was significantly associated with an increased incidence of lung cancer. Future studies may investigate specific WTC exposures and histologic changes and clarify the role of WTC exposure for prognosis.  Corresponding Author: To contact the corresponding author, Sean ...

Streamlining the consciousness debate, from trees to hermit crabs

2025-10-09
Beyond spirited dinner party debate, establishing which creatures have consciousness matters in terms of animal welfare and conservation policy. A Michigan State University philosophy scholar has added clarity to a messy philosophical debate. In this month’s journal Biology & Philosophy, PhD candidate Jonah Branding contributes a decision tree that can be applied to questions such as, do fish feel pain when they’re on a hook? Does an ant feel alarm when protecting its colony? Do banana slugs feel anything when they eat dead leaves on the forest floor? Or are these simpler organisms more like stimulus-response machines, which don’t have any mental experience? “There ...

Polyherbal dietary supplement MD-1 ameliorates severity of type 2 diabetes mellitus in high-fat diet-fed C57BL/6J mice by attenuating adipose tissue inflammation

F. & Thoms, Emblica officinalis Gaertn., Eugenia jambolana Lam., Gymnema sylvestre R. Br. Ex, and Cassia auriculata Linn. This study aimed to investigate the in vivo effects of MD-1 in high-fat diet (HFD)-induced diabetes mellitus in C57BL/6J mice. Methods After 10 weeks of HFD induction, diabetic mice (n = 60) ...

Long-term continuous monitoring of new-onset atrial fibrillation after coronary artery bypass grafting

2025-10-09
About The Study: Although the incidence of new-onset atrial fibrillation (AF) after coronary artery bypass grafting (CABG) in this study was higher than previously reported, the AF burden in these patients was very low, especially after 30 days. The very low AF burden questions the current guideline recommendations that long-term oral anticoagulation should be considered in patients with new-onset AF after CABG.

Emergency Medicaid spending for undocumented immigrants in the US

2025-10-09
About The Study: In this nationwide analysis, emergency Medicaid accounted for only a small fraction of total Medicaid expenditures. Although states with larger undocumented populations spent approximately 15 times more per capita, emergency Medicaid still constituted less than 1% of overall Medicaid spending even in states with large undocumented populations, posing a limited fiscal burden on Medicaid. These results suggest that cuts to emergency Medicaid will produce minimal overall cost savings and will disproportionately harm states with large undocumented populations. Corresponding Author: To ...

BfR Consumer Monitor: Not many people are concerned about raw milk

2025-10-09
What it's about: Raw milk (untreated milk) enjoys a certain popularity, but poses health risks. To avoid food poisoning, it should be boiled before drinking. But how well is raw milk actually known among the population? How do people perceive its health risk? Two-thirds of those surveyed had already heard of raw milk. Only ten percent expressed concern, making raw milk the topic of least concern of the risks surveyed. This is according to the BfR Consumer Monitor, a regularly conducted representative survey by the German Federal Institute for Risk Assessment (BfR). “The health risks of raw milk ...
