Researchers examined AI‑enabled HR tools in 61 companies across Bangladesh. They surveyed 487 full‑time employees from these firms at two moments, five weeks apart. The first round captured perceptions of the technology, while the second round measured outcomes such as satisfaction, engagement, performance, wellbeing and turnover intent. The data revealed that AI‑driven HR practices raised job satisfaction, kept workers more engaged, improved performance metrics and boosted overall wellbeing. At the same time, employees reported a lower desire to quit their jobs. These benefits happened because staff felt they fit better with the organization and because they felt more empowered when they trusted the system and were not worried about privacy. When trust is weak or privacy concerns are hi

Every year, rabies kills about 60,000 people, mostly in Africa and Asia. Most of these deaths come from dog bites. Vaccinating dogs at scale is key to stopping the disease. Experts say herd immunity kicks in when over 40% of dogs are vaccinated. That is the target. But getting there is tricky. In Tanzania, researchers tested two ways to deliver vaccines to dogs. One used traveling teams. The other trained local community members to do the work. They ran a three-year study across 112 wards. Half used the team-based method. The other half used community-based delivery. The results were clear. Community-based delivery reached 55% coverage on average. Team-based delivery only hit 37%. Worse, team-based coverage dropped each year. By year three, it was well below the 40% mark. Community-based d

Physicists at CERN have just published groundbreaking work. For the first time, they directly measured quantum entanglement between Z bosons. This happens when two particles share a mysterious connection across space. The study relied on proton-proton collisions at the Large Hadron Collider. Two energy settings were used: 13 tera-electronvolts and 13. 6 tera-electronvolts. The ATLAS detector captured the necessary data. The team focused on Higgs boson decay events. They tracked how Z bosons transform into other particles during specific interactions. Angular measurements revealed clues about quantum correlations. Two key coefficients emerged from their analysis. The first number was negative at -0. 71 with an uncertainty of plus or minus 0. 45. The second number was small and positive at 0. 0

Researchers used data from the 2019 National School Health Survey to see how movement habits relate to diet, lifestyle, and how teens view their own health and body. They wanted to find links between how much teens move and what they eat or do. The study grouped physical activity done in different settings and screen time into separate behavior patterns. Then they ran Poisson regression analyses, adjusting for sex, age, race, skin color, and mother’s education. Significance was set at p

The medial collateral ligament on the inside of the knee usually fixes itself after a sprain. But sometimes it doesn’t heal all the way. When that happens the joint can feel loose, especially on the inner and front side. That looseness can put extra stress on nearby parts like the anterior cruciate ligament, the meniscus and the cartilage. Because of this risk, doctors wanted a clearer way to talk about injuries that involve both the MCL and the ACL. They studied the ligament’s structure and how it moves under load. That work gave rise to a new sorting system called the anteromedial knee instability, or AMKI, classification. The AMKI method uses a simple three‑letter grade. First, the clinician checks that the knee can straighten fully while looking for valgus looseness; if the leg can’t

A new tool helps pinpoint where breast cancer screening matters most. Researchers built the Community Need Priority Index for Breast Cancer Screening to spot areas with low screening rates. They tested it using real data from a mobile mammography program. Between 2021 and 2025 the van visited 418 events with 176 local partners. Over 3,600 people got screened during those visits. The index splits neighborhoods into five groups based on need. The highest-need group had 243 census tracts. Nearly half of all mobile events happened there. Forty-four percent of all screened patients came from those same tracts. That shows the van went where need was greatest. Underscreening means rarely or never getting a mammogram. In the lowest-need areas only 27 percent were underscreened. In the highest-ne

People who live in places where fresh food is hard to find tend to follow Brazil’s healthy eating guide less closely. A recent study in the northeastern capital of Natal shows that adults and older residents there have lower scores when they live in food deserts. The research used a cross‑sectional design, matching each person’s diet score with the type of food environment around them. Data came from the BRAZUCA Natal project, which recorded gender, age, monthly income, and how well each person followed the national food guide. Statistical analysis showed that living in a food desert reduces the overall adherence score by about 2. 4 points, regardless of income, age, or gender. It also cuts the score for eating habits that go against the guide by roughly 1. 4 points. In contrast, neighborh

Scientists discovered two brand new atomic arrangements on a common titanium dioxide surface. These patterns, called Ti3O2-(2×1) and Ti3O4-(2×1), showed up after a massive computer search. The first one beats the old leading model by a clear margin. It matches weird rosette shapes seen in real microscope images. Researchers tested 80 different versions of the Ti3O2 structure to figure out why some last longer than others. The secret lies in how electrons behave. Titanium atoms that lost a few electrons create small electron clouds called polarons. These clouds mix strongly with electron clouds from oxygen atoms in the rebuilt lattice. This mixing acts like glue. Structures with more mixing stay stable. Structures with less mixing fall apart. The mixing is so specific it picks out the best

Scientists have found a single rule that describes how wide the borders between magnetic regions can be. These borders, called domain walls, appear in many kinds of magnets. The new rule works for ferromagnets, antiferromagnets, and ferrimagnets alike. It covers materials with simple or very intricate atomic arrangements. The breakthrough comes from linking the shape of a domain wall to the way spin waves travel over long distances. Spin waves are tiny ripples in the magnetic order. By studying these ripples, researchers built a formula that predicts wall width without guesswork. The same math applies whether the material is a three‑dimensional crystal or a two‑dimensional sheet like honeycomb or kagome lattices. To test the idea, the team ran massive computer simulations that mimic atom

Southern and Eastern Africa show stronger health system resilience compared to Western and Central regions. Central Africa has the highest concentration of countries stuck in low resilience. This pattern comes from a study tracking 25 nations over 23 years. Researchers used a scoring system and a math model to measure how health systems handle diseases like Ebola cholera and measles. They grouped each country-year into low medium or high resilience based on disease control funding surveillance and recovery ability. The model shows low resilience states tend to stay low with an 82 percent chance of remaining there next year. Medium resilience has about a 19 percent chance to improve but also an 18 percent risk of sliding back. High resilience holds steady 64 percent of the time but still

Many evaluations of global health projects rely on ideas that come mainly from Europe and North America. This approach can push aside other ways of knowing and create unfairness in knowledge. Scholars have started to question this pattern and have produced a growing body of work on decolonising evaluation. To map this work, researchers ran a scoping review. They searched academic databases and found 1,024 records. After removing duplicates, 732 records were screened by title and abstract. Adding 138 reports from grey literature and citation chasing gave 653 full‑text reports to examine. From these, 59 studies were kept for the final synthesis. The analysis showed two linked strands of thought. One strand tries to take apart colonial structures that still shape evaluation methods. The oth
