The tuberculosis rate among Inuit living in Nunavik, the Inuit land of northern Quebec, is 1,000 times higher than the rate among non-foreign-born Quebecers, and a lack of local medical resources exacerbates the burden of tuberculosis, a new study published in 2006 found. CMJ (canadian medical association magazine) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.251824. The study, conducted in collaboration with Nunavik Inuit and led by a primarily Indigenous research team, aims to assess current Inuit experience with tuberculosis treatment and derive recommendations from Inuit for effective disease eradication strategies. First Nations and Inuit researchers interviewed 156 Nunavimiut (Inuit people from Nunavik). Of these, 61% were…
In Japan, which has entered a super-aging society, the burden of medical expenses and social security costs is increasing. In response, national policy is promoting ‘compact-plus-network’ plans to encourage people to live closer to public transport and reduce dependence on cars. A team led by Sayana Wakisaka and Associate Professor Haruka Kato from the Graduate School of Human Life Ecology at Osaka Metropolitan University, in collaboration with the Future Co-Creation Laboratory at Japan System Techniques Co., Ltd., investigated whether opening a new station could reduce medical costs. The researchers used a natural experiment created by the staggered opening of the…
Artificial intelligence consumes enormous amounts of electricity in the United States. According to the International Energy Agency, AI systems and data centers used approximately 415 terawatt-hours of electricity in 2024. This accounts for more than 10% of the country’s total electricity production, and demand is expected to double by 2030. This rapid growth has raised concerns about sustainability. In response, researchers at the School of Engineering have created a proof-of-concept AI system designed to be much more efficient. Their approach has the potential to reduce energy usage by up to 100 times, while also improving task performance. A hybrid approach…
A Canadian research team has identified a new way to slow the growth of glioblastoma, the most aggressive and currently untreatable type of brain tumor, and also pointed to existing drugs that could be used to treat it. The study revealed that some brain cells previously thought to only support normal nerve function may actually help glioblastomas grow and spread. These cells send signals that strengthen tumor cells. When scientists blocked this communication in a laboratory model, tumor growth was significantly reduced. This finding also highlights potential therapeutic opportunities. Researchers have found that drugs already used to treat HIV may…
Despite the great diversity of languages spoken around the world, certain grammatical patterns continue to emerge. A new study finds that about a third of long-standing “linguistic universals” are supported by strong statistical evidence when tested using modern evolutionary methods. An international research team led by Annemarie Verkerk (Saarland University) and Russell D. Gray (Max Planck Institute for Evolutionary Anthropology) analyzed 191 proposed universal words using Grambank, the largest database of grammatical features ever collected. Their dataset covered over 1,700 languages. In previous studies, linguists tried to avoid similarities between related or nearby languages by selecting samples from distant regions.…
Recent research published in Journal of Experimental Psychology: General It suggests that people consistently judge creative writing more harshly if they believe it was created by artificial intelligence. This bias seems incredibly difficult to overcome and is indicative of a deep-seated human preference for human-created art. Generative artificial intelligence refers to computer programs that can generate new text, images, or music by predicting patterns from large amounts of data. Tools like ChatGPT and Claude allow you to write essays, poems, and stories that look like they were written by a real person. As these technologies become more common, scientists wanted…
The acute effects of psilocybin slow human reaction times and mildly impair the parts of cognition that regulate behavior. These short-term effects vary depending on the dose of the drug, highlighting the need for monitoring and safety measures while the substance is active in the body. The findings were recently published in the journal Psychopharmacology. Psychedelic substances are increasingly being evaluated for their therapeutic potential in treating conditions such as anxiety and depression. As these drugs move toward wider clinical acceptance, researchers are attempting to understand exactly how these drugs alter immediate thought processes. Cognitive functions, especially executive functions, are…
Perched atop a cliff in Tasmania’s remote north-west corner, the 80-metre-tall tower and small hut look rather unassuming.But it was this site that helped deliver the monumental proof that humans are changing the Earth’s climate.The Kennack/Cape Grimm Air Testing Station, run by a small team of scientists, also provided evidence that change can happen when the world comes together.And as it celebrates its 50th birthday, this place that has been making history for half a century may be more important than ever.Loading…One world, one atmosphereFormer CSIRO scientist Graham Pearman was one of the few people originally involved in setting up…
The way psychological scientists think on an individual level is tied to the theoretical camps they attend and the research tools they prefer. These individual intellectual habits help explain why deep disagreements persist in science, even when researchers examine the same data. The study was published in the journal natural human behavior. The traditional view of science assumes that accumulating data will ultimately settle academic debates. According to this perspective, disagreements between researchers are usually caused by differences in what they know. As evidence mounts against an outdated idea, the scientific community theoretically discards it and creates a more accurate…
A study using online and social media posts in the United States found that people tend to feel worse during the two annual transitions to daylight saving time (spring) and standard time (fall). This deterioration in mood becomes more pronounced after the change to standard time in the fall. The paper was published in pro swan. Seasonal time change is the practice of adjusting your clock twice a year. In the spring, usually in March, clocks are moved forward one hour to enter daylight savings time. This change is described as one hour of sleep “lost.” In the fall, usually…
