A year after stopping taking weight-loss drugs such as Ozempic or Wegoby, people regain 60% of the weight they lost on average, but beyond that the weight plateaus and some people manage to keep 25% of the weight they lost on treatment, say researchers at the University of Cambridge. However, it is not clear whether the weight gain consists of both fat and muscle, or whether it consists primarily of fat. Previous research suggests that lean body mass, including muscle, may account for up to 40% of the total body weight lost during treatment. More than 1 billion people worldwide…

Researchers at the University of Connecticut reported on March 2, 2026 that teenagers across the country are sleeping less. Japan Automobile Manufacturers Association. And the problem appears to be social. Teens not getting enough sleep has been reported as a problem in the medical literature since at least the early 20th century. A 1905 Lancet study of the sleeping hours of boys attending British boarding schools worried that night lights were preventing them from getting enough sleep, and suggested that “it is neither physiological nor prudent to go to bed late and rise early.” By the late 1950s, public attention…

Teeth can contain surprising clues about how people lived thousands of years ago. New research published in open access journal Pro SwanThe study, led by Roberto Germano of Sapienza University of Rome and colleagues, shows how the teeth of Iron Age Italians preserve detailed evidence of their health, diet and early life experiences. Understanding the daily life of ancient cultures requires reliable biological records. Teeth are particularly valuable because they are extremely durable and retain microscopic signs of growth and change. Researchers combined several types of dental analysis to examine people buried at Ponte Cagnano, an Iron Age site in…

Recent research published in natural aging demonstrate that a simple blood test can accurately detect Alzheimer’s disease and other forms of dementia in a highly diverse population in Latin America. By combining these blood markers with standard memory tests and brain scans, clinicians can dramatically improve their ability to diagnose memory loss conditions in historically underdiagnosed areas. Dementia is an umbrella term for a variety of conditions that cause a progressive loss of thinking and memory skills. Alzheimer’s disease is the most common cause of dementia in older adults. Frontotemporal lobar degeneration is another distinct type of dementia that primarily…

Stiff knees, lower back pain, and persistent joint pain are often dismissed as signs of normal aging. However, osteoarthritis, the most common joint disease worldwide, is not treated in accordance with actual research findings. Experts say the biggest gap is not a lack of options, but a lack of access to the most effective options. The most powerful treatments are not found in prescription bottles or operating rooms. It’s movement. However, in many countries and health systems, patients are rarely taught the only treatment proven to reduce pain and protect joints: exercise. Exercise is widely recognized as one of the…

Taking aspirin daily is not a quick or reliable way to prevent bowel cancer for most people, according to a new Cochrane review. This analysis also highlights some clear downsides. Regular use of aspirin increases the risk of serious bleeding soon. Bowel cancer, also known as colorectal cancer, is one of the most common cancers worldwide. Prevention usually focuses on healthy lifestyle choices and regular screening tests. In recent years, scientists have investigated whether widely available drugs such as nonsteroidal anti-inflammatory drugs (NSAIDs) may help lower the risk. NSAIDs, such as ibuprofen and aspirin, are commonly used to treat pain,…

Research published in Journal of Child Psychology and Psychiatry They found that letting babies cry every now and then does not impair their behavioral development or their bond with their mothers. This study suggests that parents who let their infants fuss for a while are not causing long-term psychological damage. These results provide reassurance to parents navigating the daunting challenges of infant sleep and crying. For decades, parents and psychologists have debated how quickly caregivers should respond to a crying baby. One school of thought, based on attachment theory, suggests that parents should immediately soothe a crying baby. Attachment theorists…

Almost a year and a half after infection, researchers investigated whether long-term COVID-19 infections leave measurable traces of inflammation and nerve damage in the blood, and the results cast doubt on assumptions about sustained immune activation. Study: Long-lasting coronavirus: assessment of circulating markers suggests absence of brain neuron damage, neuroinflammation, and systemic inflammation – controlled study. Image credit: p.ill.i / Shutterstock Recent research published in journals scientific report We analyzed circulating biomarkers of systemic inflammation and neuroinflammation in patients with long-term novel coronavirus (LC). Background and long-term spread of the new coronavirus infection LC is emerging as a global health…

Australia’s Veterinary Medicines Regulatory Authority has suspended the use of florfenicol in Tasmanian salmon, citing the “unacceptable risk” the antibiotic poses to other species.The Bob Brown Foundation said the Australian Pesticides and Veterinary Medicines (APVMA) decision was “an indictment on industrial aquaculture companies and a complete disregard for the marine environment”.The APVMA granted emergency authorization in November 2025 to allow industry to use florfenicol to treat outbreaks of the bacterial disease pishiriketsiosis.

BOSTON — How far will Robert F. Kennedy Jr. go in reshaping public health policy in his image? Can we encourage Americans to maximize their exposure to measles to achieve herd immunity? The Ministry of Justice also seems to think so. In defending the Surgeon General’s changes to the pediatric vaccination schedule and federal vaccine advisory committee in federal court Wednesday, government lawyers said Kennedy and other health officials have broad discretion to issue such guidance and choose the type of evidence to consider and the experts to consult.
