A group of sixteen female rugby sevens players from national teams took part in a running test. They ran forward and backward over a track, starting at 40 % of their top speed and going up to 100 %. Sensors in the floor measured ground force, and motion‑capture cameras recorded joint positions. They wore lightweight markers on hips, knees and ankles. The force plates measured how long each foot stayed on the ground and how hard it pushed. The cameras tracked the three‑dimensional motion of each joint. Up to about 6 m/s forward and 3. 3 m/s backward, the athletes made longer steps by pushing the foot farther ahead and letting the leg swing more. Ground contact distance and swing distance both rose with speed in that low‑speed range. Stride length, which is the sum of those two distances, in

A recent study looked at how student programs help young people come up with new businesses. Researchers surveyed 269 undergraduates at a Nigerian university that has an entrepreneurship center. They wanted to see if getting involved with such centers actually helps students think creatively about starting companies. The team used special statistical tools to check their results and make sure the data was solid. The numbers showed that being active in those student programs did boost creative idea production. Students who engaged more with the center tended to generate more innovative business concepts. But here's where it gets interesting—when students felt the overall economy was doing poorly, that positive link weakened. Bad economic news seemed to dampen the benefit of having a strong

Researchers examined whether narcolepsy was linked to more than sleep-related concerns. They used electronic health records and survey responses from the All of Us Research Program, covering January 1, 2009, through July 31, 2022. The design was retrospective and observational. The team matched 694 participants with narcolepsy to 2,072 participants without it, creating a 1:3 comparison. The full group averaged 49 years of age, and 70% were women. Employment and social conditions revealed a notable divide. Even though education levels were high, 38. 5% of the narcolepsy group were out of work or outside the workforce, compared with 29. 2% of the other group. Among survey respondents, 259 people with narcolepsy and 768 without it answered questions about social determinants of health. The nar

Researchers combed through massive medical archives to discover drug-free options for teenagers living in Southern European countries. Their hunt pulled in over 6,000 abstracts before narrowing down to just 35 credible studies. This group covered mental wellness programs, movement-based therapies, special eating plans, and blended treatment mixes. Each category offered different angles on how to ease persistent discomfort without relying on medication. The search began on March 11, 2025, scanning top databases like PubMed, Embase, SciELO, and PsycInfo. Two separate reviewers independently filtered each paper until they reached a consensus on what counted as strong evidence. This careful process ensured the final list reflected real-world effectiveness rather than random hits. By cross-che

Doctors looked at 28 people who needed a second fix on a leg artery after the first operation didn't stay open. One group received a loop clean‑out from the thigh artery and the blocked shunt was removed. The other group got a new bypass made from a vein or a synthetic tube. The average time between the first and second surgery was about sixteen months for the first group and seventeen months for the second group. In the first group, no early clots, deaths, or other heart problems were seen. In the second group, one patient developed a clot in the new bypass and needed another small operation to connect the lower leg, but there were no deaths or major heart issues. After one year, three years, and five years, the first group’s artery stayed open in about ninety‑three percent, ninety‑thr

A research group brought together 412 adults ranging from forty to seventy-five years old for a comprehensive two-year investigation. During this period, scientists measured both standard executive function assessments and precise smartphone usage patterns. The central aim was to determine whether the manner in which individuals engage with their electronic devices could either accelerate or decelerate natural mental aging. To uncover potential connections, the team employed advanced latent growth curve modeling within a structural equation framework. The results demonstrated that executive functions naturally deteriorated over time, with declines becoming notably steeper after age sixty. Among participants who dedicated at least three and a half hours per day to cognitively stimulating d

Doctors studied how many patients struggle with stiff shoulders after rotator cuff repairs. They looked at 352 people who had the surgery done through small incisions. The team measured flexibility, pain levels, and other health markers. They also asked each patient what held them back from getting better during the first three months. After three months, nearly half of the patients showed signs of ongoing stiffness. Those who felt anxious about their tendon might not heal fully. Pain turned out to be the biggest reason some people stayed stiff. When pain was the main issue, almost two-thirds of those stuck with stiffness said so. The study found that higher pain scores at the three-month mark predicted problems later on. The research suggests that fear about tendon damage matters more t

The number of PCI procedures has exploded over the past ten years, both in Russia and around the world. More surgeries mean more chances for problems. Two issues stand out for doctors: blood clots forming inside a stent and blockage of the radial artery used for access. These complications can hurt long‑term results, so researchers have spent a lot of time studying them. Stent thrombosis happens when a clot blocks a newly placed stent. Doctors have grouped the risk factors into three main categories. Procedural factors include how the catheter is handled and the type of stent used. Patient factors cover things like age, diabetes, and high cholesterol. Pharmacological factors involve the drugs given before and after the procedure, such as antiplatelet therapy. Understanding each group help

When surgeons perform carotid endarterectomy under regional anesthesia, they may decide to insert a temporary intraluminal shunt to prevent dangerous blood flow issues. A large-scale review examined how different measurement tools agree with actual patient symptoms and helps doctors choose when to place such a shunt. The team searched major medical databases from early 2015 through late 2025 for prospective studies that compared various oxygen monitors and clinical assessments. They analyzed data from 13 independent trials involving 1,894 patients and calculated results using R statistical software. Key findings showed that roughly 11. 5 percent of patients needed a temporary shunt. The most reliable indicator was a reduction of at least 9-10 percent in near-infrared spectroscopy measurem

Scientists looked at how the electrical resistance of cochlear implant electrodes changes over time. They wanted to know if the contact between the electrode and the ear tissue stays steady or shifts after surgery. They studied 79 people who got cochlear implants, which gave them 136 ears to watch. Measurements were taken right during surgery, then again after one year and after five years. Twelve electrodes were checked and split into three groups: the top four (apical), the middle four, and the bottom four (basal). The top group showed almost no change in resistance across the whole five years. The middle and bottom groups had higher resistance at both the one‑year and five‑year checks compared to the surgery reading, but the resistance did not keep rising between year one and year fiv

Many people struggle to find reliable information about who they should support during party primary races. These internal party contests matter a lot for democracy, but most voters get poor quality guidance. Existing voter information apps mostly target big national elections rather than the smaller, more personal battles happening inside each party. This gap leaves citizens without clear comparisons of their choices. To fill this gap, researchers built something called PRIMARYCAN. It's an open-source tool that uses prompts to create detailed candidate profiles. The system works in two modes - a simple one for regular users and a deeper professional version. There's also an external checker that runs through the results with another model to catch mistakes. Plus, there's a guide explaini

Kidnapping cases in Nigeria's capital city, Abuja, have surged dramatically between 2021 and 2025. The numbers tell a stark story. In 2021, there were 21 reported kidnapping incidents involving 62 victims. By 2023, that figure had jumped to 50 incidents and 247 victims. Even though 2024 and early 2025 showed a slight drop in numbers, the total still reached 718 abductions over the entire period, with 34 people killed. The study looked at why this happened despite Nigeria having a National Security Strategy introduced in 2019. Researchers used real data from 167 kidnapping cases, spoke with a top security expert, and reviewed existing research. They found that the problem isn't the strategy itself, but how it's being carried out. Five major issues keep the kidnapping crisis alive: poor tea
