Teenagers who carry extra weight often find themselves caught in two problems at once. They move less over time, and they grow harsher in how they judge their own bodies. Researchers wanted to understand how these two struggles feed off each other, especially among teens living outside Western countries. A study followed 325 Chinese students, with an average age of about fifteen, across three points in time. The results painted a clear picture. Physical activity dropped steadily across the school year, while negative feelings about weight climbed at the same pace. Teens who started out more active gained those harmful feelings at a slower rate. On the flip side, teens who began with stronger weight-based self-criticism saw their activity levels fall faster. This shows how each problem can

A recent study examined two different approaches for treating plantar fasciitis, a common foot condition causing heel pain. The comparison focused on a 12-week period where patients either did exercises at home through a digital program or attended physical therapy sessions in a hospital. The researchers aimed to determine which method provided better pain relief and lower costs. Their goal was to help healthcare providers choose the most effective and affordable treatment option for patients. The investigation included 587 adults who received a confirmed diagnosis of plantar fasciitis during the years 2022 to 2024. Participants were carefully paired using a statistical technique known as propensity score matching, which helped reduce bias. The primary measurement tracked morning pain lev

Scientists across Indiana are working on a new project to figure out why some older adults stay sharp while others struggle with memory and thinking. The study looks closely at how daily life and the people around someone might affect brain health. Researchers asked 510 people from 41 Indiana counties to join the project. They were all aged 65 or older, and the average age was 69. 9 years. Most participants were women, and the group leaned heavily White and retired. Each person sat down for a long interview about their health, their daily routines, and the people they spend time with. They talked about jobs they had, hobbies they enjoy, and the support they get from family and friends. On average, people named around five close contacts in their lives. Beyond the interview, 273 volunteers

Infertility impacts millions of people everywhere. Statistics show that one in six adults deals with reproductive difficulties at some stage of their lives. Women face the toughest challenges when comparing different countries. The root causes of infertility are complex and involve many factors. For a baby to implant properly, the embryo and the uterine lining must sync up perfectly. This critical moment occurs within a narrow timeframe known as the window of implantation. Scientists have uncovered tiny chemical messages that guide this process. Special protein structures called extracellular matrix help the embryo attach and grow. Tiny messenger molecules named microRNAs also serve as important signals between cells. They communicate directly with each other and direct how the mother and

Scientists use a simple way to see where proteins are inside cells. The method lets researchers watch each cell and keep the cells looking natural. It works for one protein or many at the same time. The cells are grown on cheap glass slides that sit in normal 24‑well plates. No special plates are needed. The cells stay flat and easy to see. To stain several proteins together, they use antibodies made in different animals so they don’t mix up. Each antibody gets a different color that glows under the microscope. They also run checks like no primary, no antibody, single dye only, and overlap tests to make sure the colors don’t bleed. They keep the liquid tiny, so they use less chemicals and antibodies but still get strong signals. Any regular widefield or confocal microscope can read the

Today's pesticide safety checks have serious holes. They put too much weight on how fast bugs die before deciding if a product is safe. This method overlooks lasting damage that happens after initial contact. It also fails to account for how several chemicals interact at once. Most studies still center on honeybees while ignoring other vital pollinators. Four major weaknesses emerge from this system. One, the focus stays on immediate lethality instead of long-term effects. Two, there is no universal standard for measuring subtle behavioral changes. Three, mixed toxin exposures are handled poorly without real-world relevance. Four, honeybees serve as the sole reference while diverse bee groups remain untested. A fresh seven-part plan aims to fix these flaws. First, test a broader set of b

Scientists wanted to know exactly how a drug called lubabegron makes cattle grow bigger. This drug got approved for cutting ammonia fumes from feedlots. But nobody fully understood the biological steps behind the muscle changes it creates. The research team worked with 32 Angus-influenced steers. Each animal weighed around 524 kilograms at the start. The scientists split them into two equal groups. One group ate normal feed. The other group received feed mixed with lubabegron for 63 days. Both sets of steers had received hormone implants when they arrived at the facility, 58 days before the experiment began. The results were striking. Steers on lubabegron ended up weighing 637 kilograms on average. The control group reached only 612 kilograms. The treated animals ate more feed and turned

Doctors wanted to see if a special brain scan could guess where the trigeminal nerve moves when a tumor sits near the cavernous sinus or Meckel's cave. They looked at 28 people who had surgery to remove those tumors. Before the operation, they used a technique called diffusion tensor imaging tractography to map the nerve. They hoped the scan would help plan the safest way to reach the tumor. The scan matched what surgeons found inside the head in 26 out of 28 cases, which is about 93 percent correct. They noticed three ways the nerve got shifted: pushed to the middle, pushed to the side, or wrapped around the tumor. Seven nerves shifted toward the middle, thirteen shifted toward the side, and eight were wrapped around the tumor. Knowing which way the nerve moved helped the team decide whi

Citrus peels are usually thrown away, but they contain compounds that may benefit health. A team of scientists decided to capture those benefits in a stable, usable form. They chose mandarin peels and set out to protect their active ingredients through microencapsulation. The researchers tested two main techniques: ionic gelation and freeze-drying. Their mixture included sodium alginate, maltodextrin, gum arabic, and a small amount of aloe vera powder. The formula aimed for a 20:80 ratio of core to wall material. They varied the amounts of maltodextrin and gum arabic, keeping the total at 2%. Ionic gelation produced calcium-alginate beads that were compatible with the body but did not hold the active compounds as well. One version, IG4, with 1. 5% maltodextrin and 0. 5% gum arabic, performe
