Otitis media with effusion is a common ear problem where fluid stays in the middle ear for a long time. The condition is hard to treat because doctors cannot reach the middle ear easily, and many patients end up needing surgery. Researchers created a new hydrogel called Gel‑HADA that can be placed on the eardrum. The gel hardens in about fifteen minutes thanks to an enzyme called transglutaminase, forming a thin second membrane that sticks tightly to the eardrum. The gel can hold dexamethasone phosphate, a steroid that reduces inflammation. In a rat model of the disease, a single dose of the drug‑loaded gel lowered ear‑wall thickness, cut down inflammatory cells, and brought hearing back to normal, matching healthy animals. Tests showed the material does not harm surrounding tissue, blo

A 20‑year‑old college football player hurt his right thigh during a game. The blow was blunt and caused pain and swelling. X‑rays and a venous duplex scan showed no broken bone or clot. Doctors thought it was a simple soft‑tissue bruise and sent him home. Nine days later he came back with much worse pain, a swollen thigh, and a stiff knee. He could not walk, felt tingling, and his heart raced while his blood pressure fell. Lab tests revealed high white‑blood cells, raised creatine kinase and lactate. Pressure checks suggested compartment syndrome, so surgeons performed an emergency fasciotomy. Inside the muscle they found pus. Further imaging showed a large abscess inside the thigh and infection spreading into the knee joint. Cultures from blood and joint fluid grew Fusobacterium necroph

Scientists have built a lab-grown piece of human skin that includes the layers of real skin and living nerve cells. The construct contains a differentiated epidermis and dermis together with sensory neurons and Schwann cells that form structures similar to free nerve endings. These endings are the spots where the electrical signals start. The tissue is placed on a high‑density microelectrode array that can pick up tiny voltage changes. When a tiny probe presses on the surface, the neurons fire in a pattern that matches the force. When a small heater warms a spot, a different firing pattern appears. The shape and timing of the waves tell the system whether the stimulus was mechanical or thermal. This is the first time an engineered human skin model has shown clear electrical responses to

Many children worldwide still fall short of recommended movement. The World Health Organization updated its advice in 2020. Instead of a strict 60 minutes each day, the rule now says an average of 60 minutes per day, or 420 minutes each week. Researchers looked at five large surveys from Australia and New Zealand. They compared a simple question that asks how many days a week a child gets 60 minutes of activity with longer questionnaires like the International Physical Activity Questionnaire for adolescents. They used statistical curves to see which simple answer matched the detailed data best. The old rule was met by 28 to 55 percent of kids. Under the new rule, 35 to 84 percent qualified, an average rise of about 26 percent. The curve analysis gave scores between 0. 73 and 0. 91, showing

Healthcare in the United States adds a lot of greenhouse gases to the atmosphere. One of the biggest services is screening for colorectal cancer, which reaches about 134 million adults. The usual options are a yearly stool‑based immunochemical test, a CT colonography every five years, or a colonoscopy roughly every ten years. Researchers at a single medical center measured the resources each test uses, from the lab to the patient’s ride to the clinic. They turned those numbers into estimates of global warming potential and health damage, then ran a ten‑year Markov model with Monte Carlo simulations to see the long‑term effects. The stool test showed about twenty percent less environmental impact than a colonoscopy, and this held up in many sensitivity checks. Driving cars for appointments

PCOS is a hormonal and metabolic condition that shows up in many women of child‑bearing age. Doctors often suggest lifestyle changes, especially a balanced diet and regular exercise, to ease symptoms. Researchers searched four major databases up to February 28, 2025, and found 25 randomized trials on aerobic activity for PCOS. They evaluated study quality with the Cochrane tool and combined data from five trials that included 192 participants using a random‑effects model. The analysis showed that aerobic workouts, particularly high‑intensity interval training, lowered waist‑to‑hip ratio and reduced LDL cholesterol. Fasting insulin and HOMA‑IR scores also improved, indicating better insulin sensitivity. Changes in BMI, waist size, total cholesterol, fasting glucose, triglycerides, and HDL

Older adults who have mild cognitive problems often struggle with sleep. Bad sleep can make thinking worse and lower how they feel day to day. Many still reach for pills, even though those medicines can have safety worries. Researchers looked at whether meditation could help these sleep issues. They followed strict PRISMA rules and searched five major databases up to June 2025. The search pulled out randomized and pilot trials, plus a few quasi‑experimental studies that used trusted sleep questionnaires. Seven trials involving 434 participants met the criteria. Programs lasted from four to twelve weeks and included mindfulness, mantra chanting, sound‑based meditation, and mixed approaches. Five of the studies reported better self‑rated sleep, and one study using a sleep‑watch showed less

Lipoprotein(a) or Lp(a) is a genetic risk factor for heart disease and aortic valve problems. It's mostly inherited and can't be easily controlled with common medications. But new RNA-based treatments are giving scientists hope to target and lower Lp(a) levels. Five powerful treatments are in late-stage development. One of them, Pelacarsen, uses a special molecule to reduce Lp(a) by 80%. It's being tested in a phase 3 trial, and results are expected in late 2026. Other treatments, like olpasiran and lepodisiran, use small RNA molecules to lower Lp(a) by up to 96%. Muvalaplin is an oral medicine that blocks the formation of Lp(a) particles and reduces their levels by up to 85. 8%. CRISPR/Cas9 is a gene editing tool that targets the LPA gene and has entered phase 1 studies. All these treatm
