Lots of people talk to AI chatbots when they feel sad or scared. These bots are not real counselors. Still, many users share deep feelings with them. If a user talks about self-harm, the bot's reply can be very important. Scientists wanted to see if the way a bot remembers old messages changes its reaction during a crisis. The test used three AI models: ChatGPT, Gemini, and Doubao. Researchers built twelve sample chats. Each chat had five turns. Four chats showed clear suicide risk. Four chats showed hidden or confusing risk. Four chats showed high distress but no suicide risk. Every chat was shown to the models in three formats. One format showed only the newest message. Another format rebuilt the whole history using only user messages. The third format kept the natural back-and-forth be

The research team examined how hospital and clinic beds changed across many Chinese counties from 2015 to 2023. They focused on whether new beds were driven more by local planning rules or by each area’s financial strength. The study covered 1,787 stable counties that are not part of larger districts. It used a mix of statistical tools to account for differences between counties and across years, compared neighboring areas, and tracked how regions moved in and out of high‑gap categories. The goal was to see if supply matched the real need in each place. On average, each 10,000 residents had about 35 beds in 2015, and that figure rose to roughly 54 beds by 2023. The gap between planned supply and actual need stayed roughly the same over the period. Both planning factors and money explained

Scientists are finding tiny organisms in the gut that might signal colon cancer early. These microbes leave clues in stool samples. Researchers use computers to spot patterns linked to disease. But a big problem exists. Tests trained on people from one country often fail in another. Diet, lifestyle, and genes change the gut microbiome. A test built on data from Europe might not work well in Asia or Africa. This makes it hard to trust any single tool worldwide. A recent project tried to fix this. It gathered data from many studies across different nations. The goal was to see which microbe signals stay true everywhere. They called this effort a benchmark. Think of it like a universal test for the tests. It checks if a cancer predictor works across borders. Early results show most current m

Mouth cancer is becoming more common around the world. Over the past ten years, daily habits and the environment have driven up the number of cases. This type of cancer is called oral squamous cell carcinoma. Finding it early can save lives. When diagnosis happens too late, the chances of survival go down. Scientists study a group of enzymes known as matrix metalloproteinases, or MMPs. These enzymes need zinc and calcium to work. They break down the support structure that holds body tissues in place. In oral cancer, MMPs help tumors grow, invade nearby areas, and spread. Researchers knew MMPs were involved, but they were not sure how well they predict patient outcomes. A team examined all 23 human MMP genes. They searched two large genetic databases, the Gene Expression Omnibus and The C

Older people with weak bones often break the back of their heel. This injury happens when the Achilles tendon pulls a piece of bone away. Doctors sort these breaks into three groups using the Beavis system. The first and third types leave tiny bone chips that screws cannot hold well. Regular open surgery cuts a long incision. That big cut often leads to dead skin and wounds that refuse to heal. A research team tried a different trick. They used a special stitch pattern called a modified Bunnell suture. They threaded it through a tunnel drilled in the heel bone. This method lets the surgeon choose a tiny cut or a standard one depending on the case. The idea is to grip the bone firmly while being gentle to the skin and nerves. Between January 2024 and February 2026 two patients got this tr

A recent study from Thailand looked at how different ways of working affect people's health. Researchers used data from the Thailand Health and Welfare Survey to explore connections between job types and well-being. The team focused on self-rated health, food variety, exercise habits, and habits like smoking and drinking. They wanted to see if being self-employed changes how people live and feel. The results show that self-employment is linked to lower self-rated health. People who work for themselves often eat less diverse meals. They also tend to move less and are more likely to smoke or drink alcohol. These patterns weren't the same for everyone. Those who own their own business or work for an employer tended to stay healthier. Solo self-employed workers faced bigger risks for poor die

Active parents tend to get along better with their young children. Researchers wanted to test this idea and find out why it happens. They looked at how moving the body connects to feelings inside the home. Seven hundred nineteen parents took part in the survey. They lived in six Chinese cities: Chengdu, Suining, Meishan, Lanzhou, Xianyang, and Xi'an. The team used convenience and snowball sampling to recruit them. One parent answered every question. Surveys measured physical activity, emotion regulation, personal wellbeing, and the connection between parent and child. Researchers ran the data through AMOS 23. 0 and SPSS 29. 0. The results showed a clear direct link between how much a parent exercises and the quality of the relationship with their child. Exercise also helped parents handle

Living with a long-term health condition can make mental health struggles feel even heavier. Many people turn to apps or online tools for quick support. AI chatbots are now being tested as a first step for those dealing with depression or anxiety alongside illnesses like diabetes or chronic skin issues. The goal is to see if these bots can offer real help without replacing professional care. Digital support can feel convenient, but it also has limits that matter. Researchers built twenty different patient stories to test this idea. Half of the stories focused on type 2 diabetes, and the other half focused on chronic hives. Each story showed either mild or moderate mood troubles, plus problems specific to the disease. For diabetes, the scenarios included questions about managing blood suga

Doctors struggle to keep people in opioid treatment programs. Many patients stop early, which hurts recovery. Researchers used a big U. S. database of treatment records from 2015 to 2019. They built four computer models to guess if a patient would quit early or stay in care for 180 days. The data covered people who got outpatient medication for opioid use disorder. When they checked the results, the models were off more for Black patients and for older adults. They also saw that race and age influenced the predictions differently for each group. This shows fairness problems even when overall accuracy looks okay. Trying to fix the bias with pre‑processing, in‑processing, or post‑processing steps lowered some gaps. But these fixes often raised errors for other groups or made the model less

After decades of war, Colombia's communities faced deep psychological wounds. The peace treaty brought hope, but many people still felt isolated and distrustful. Development and peace programs were launched to help heal these wounds. Their goal was to rebuild trust and strengthen social bonds across the country. These initiatives focused on rebuilding what was broken by years of conflict. Researchers spoke with 17 community leaders to understand how these programs worked. They used interviews and qualitative analysis to see real changes. The study found that people moved from fear and exclusion to feeling more connected. Citizens started taking more part in decisions that affected their lives. The analysis showed that trust grew and new networks formed among neighbors. The programs also

A recent investigation looked at how Chinese college students handle AI summary tools and whether that impacts their deep understanding of texts. Researchers noticed that many learners reach for quick AI summaries, which can reduce the effort needed to process material thoroughly. The study aimed to see if a deeper style of thinking could bridge the gap between using these tools and actually grasping the content. The team gathered data from 608 undergraduates across three universities in Changchun, China. About 54% of participants were female, and the average age was roughly 20 years. Students completed a short survey on how often they used AI summary generators, a questionnaire measuring deep‑processing habits, a scale assessing their drive to read, and a custom test of reading comprehen

Informal waste pickers (IWPs) are a big part of how cities handle trash, yet their work is often overlooked. While this practice has long been studied in developing nations, it is only recently gaining attention in places like Barcelona, Spain. Researchers decided to take a close look at how these workers fit into the city's recycling system. They gathered information through on-the-ground observations, surveys, talks with community members, and data from other sources. The numbers they uncovered were striking. Between 1,640 and 1,940 people work as informal waste pickers in Barcelona, putting in nearly 60 hours each week for roughly €2 per hour — far below the country's minimum wage. These workers handle a massive share of the city's metal waste, collecting between 33% and 39% of it. Thei
