Postmenopausal women who were insufficiently active before diagnosis but sufficiently active after diagnosis had a 50% reduced risk of overall mortality.
A study on male spider mating found that they possess nervous tissue and sensory organs in their copulatory organs, contrary to previous beliefs. This discovery suggests that these organs may play a role in the transfer of sperm and assessing female spiders during mating.
A study analyzing NHS hospital data found Lyme disease patients in England and Wales are predominantly white and female, with peaks of new cases at certain ages. The findings may inform health promotion messages and highlight a poor understanding of recommended care pathways for symptoms related to Lyme disease.
Researchers observed bonobos in swamps foraging on aquatic herbs rich in iodine, a critical nutrient for brain development. This finding suggests that prehistoric humans may have obtained iodine from natural sources, potentially explaining their nutritional needs.

The study identified nearly all pesticide cancellations in the US as being done voluntarily by the industry.
Researchers developed an automated cough analysis technology integrated in a smartphone app, achieving high accuracy (81-97%) in diagnosing asthma, croup, pneumonia, and other respiratory diseases. The tool may enable targeted treatments to begin sooner by removing the need for clinical examinations.
A study of 1,726 US adults found that dating app users are more likely to engage in unhealthy weight control behaviors such as vomiting, laxative use, or diet pill use. The authors warn that the image- and appearance-focused nature of dating apps could exacerbate these behaviors.
Researchers warn that current vaccination policies may not be enough to prevent measles resurgence in seven high-income countries. The study suggests that countries like the UK, Ireland, and US would benefit from compulsory vaccination at school entry to achieve stable herd immunity levels.
A new CRISPR/Cas9 system allows for precise gene knock-in in live cancer mouse models, improving efficiency and control over gene insertion. The system was used to model intrahepatic cholangiocarcinoma, a type of liver cancer, and successfully induced tumor formation in mice.
Researchers found mostly human-associated microbes on the ISS, including opportunistic pathogens like Staphylococcus aureus. The study provides a comprehensive catalogue of bacteria and fungi, which can help improve safety measures for NASA's deep space human habitation.
A new study estimates the risk of cancer associated with moderate levels of alcohol consumption and compares it to the risk of smoking. The study found that drinking one bottle of wine per week is equivalent to smoking five cigarettes for men and ten cigarettes for women.
Researchers estimate that alcohol use during pregnancy and drunken driving are linked to substantial harm beyond the drinker, including fetal alcohol syndrome and road traffic fatalities. Effective prevention strategies targeting vulnerable populations, such as pregnant women and road users, are necessary.
Researchers discovered a new species of bacterium, Chryseobacterium nematophagum, that can digest roundworm parasites from the inside out. The bacteria produce specific enzymes that break down chitin and collagen, making them effective against various parasitic nematodes.
A study examines how costume changes in Star Wars female leads Padmé and Leia parallel shifts in their positions of power and romantic relationships. The researchers argue that these changes contribute to the objectification of women through costume design, highlighting the importance of considering the portrayal of women in media.
Researchers found that 'cuckolder' males and the mother's social partner were more related than expected by chance. This phenomenon allows for inclusive fitness benefits to mitigate costs of cuckoldry, where closely related males work together to compete against host males.
A nationwide study investigated socioeconomic disparities in nitrate concentrations in US drinking water, finding that Hispanic residents and systems serving low-income communities had higher nitrate levels. The study suggests that programs targeting these communities may not be effectively assisting them.
Researchers found that patients with more long-term conditions were more likely to miss appointments and had a higher risk of mortality. Patients with mental-health-based LTCs were associated with a higher risk of missing appointments than physical LTCs.

A recent study published in Canine Genetics and Epidemiology found that Labrador retrievers are prone to several health issues, including obesity and ear infections. The study analyzed data on over 33,000 Labrador retrievers and revealed that chocolate-colored Labradors are more likely to develop skin and ear problems.
Researchers found that up to 12% of bacteria on average were alive and able to reproduce in dark rooms. In contrast, only 6.8% of bacteria exposed to daylight and 6.1% of those exposed to UV light remained viable. This suggests that daylight can reduce the risk of dust-borne infections by killing dust-dwelling bacteria.
A study published in Parasites & Vectors found that host decoy traps baited with human or cattle odour can effectively collect outdoor-biting mosquitoes, including the main malaria vector species Anopheles arabiensis. The traps outperformed traditional methods such as human landing catch and caught more mosquitoes than expected.
A high-fat diet in female mice affects their offspring's obesity, insulin resistance, and addictive-like behaviors for three generations. The study found that only females showed addictive-like behaviors, while males showed obesity characteristics in the third generation.
Researchers found that frequent media multitaskers were more likely to rate an interviewee as less conscientious when in a messy room, regardless of the video subject's environment. Media multitasking affects how people perceive their surroundings and form impressions of others.
A new study found that more young people in England are choosing not to drink alcohol, with a rise in non-drinkers among 16-24 year olds. The trend is attributed to an increase in individuals who had never been drinkers, as well as decreases in excessive drinking and binge drinking.
A systematic review of indoor tanning legislation found poor compliance with risk-reducing measures, including parental consent restrictions, protective eyewear, and warning labels. The study suggests that increased enforcement and better communication are needed to protect public health.
