A brand‑new correction steps forward to explain how scientists tackled the nasty chemical erosion that forms at the border between the electrode and the electrolyte inside lithium metal batteries, a spot that can quickly wear out the cell and raise safety worries. They applied an ultra‑thin layer of a ferroelectric material that lines the interface and arranges its electric dipoles in a way that blocks the harmful reactions, keeping the surface stable while the battery charges and runs. When the dipoles are neatly ordered, the aggressive chemicals find it tougher to attack the metal, so the battery can store more energy and stay safer for longer, which is a big win for electric cars and everyday gadgets. The update also mentions the original article’s DOI, showing that this correction i

Between 2013 and 2023, there were about 6. 7 million hospital stays for brain and nerve conditions among Medicare patients. That sounds like a lot, but the number of stays actually fell by roughly one third. Fewer people were admitted for neurologic care over those ten years. Even though admissions dropped, the bill hospitals sent for each stay grew a lot. After taking inflation into account, the average charge per stay jumped from roughly forty‑eight thousand dollars to about seventy‑seven thousand dollars – an increase of about sixty percent. Meanwhile, what Medicare actually paid per stay rose only twenty‑five percent, from about ten‑two thousand to twelve‑eight thousand dollars. Because payments lagged behind charges, the shortfall ratio climbed from 0. 74 to 0. 80. Hospitals in big cit

AI tools are changing how doctors diagnose and treat patients. But these systems can accidentally copy unfair patterns from old medical records. That means some groups might get worse care without anyone noticing. Most bias fixes only look at one problem at a time. Real patient data is messy. It has many types of bias all mixed together. This makes it hard to catch every issue before it affects care. Researchers built a step-by-step plan to find and fix these hidden problems. The plan checks for five main types of bias in health data. It also tests how well AI models work for different patient groups. They tested this plan on real hospital data from over 130 US hospitals. The data covered diabetes patients. They split the data so 80% trained the AI and 20% tested it. One version used a

Not eating well causes real damage to people’s health. Doctors have not had great ways to fix that problem. Now, a new idea is growing. It is called "Food is Medicine," or FIM for short. These programs try to stop sickness or help manage it by giving people healthy food. They also work on the reasons why eating right feels so hard. FIM comes in different forms. Some programs hand out produce or groceries. Others give meal kits or already cooked meals. Some pair food with lessons about nutrition. The main goal stays the same across all types. They want to remove the gap between knowing what to eat and actually getting it. Studies on FIM show some good news. Many participants see better blood pressure, blood sugar, and cholesterol numbers. Some use the hospital or emergency room less often

Scientists wanted to understand why some athletes completely fall apart when the pressure is on. You know that feeling when you are about to do something important and your brain just goes blank? Some people experience this so severely that it ruins their performance. The researchers decided to look into whether a special kind of hypnotherapy could help. Eight athletes volunteered for this study. The group included one fencer, one soccer player, one baseball player, and five golfers. All of them struggled with choking under pressure. The researchers used a technique called affect bridge age regression. This means they guided the athletes back to early memories while they were in a hypnotic state. The goal was to find connections between past emotional experiences and their current struggl

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
