Senescence uncovered: Scientists find worms can mimic mammalian cell aging process

Low-income patients—and their health care providers—are less likely to challenge denials of their health insurance claims than those with household incomes above $50,000, according to University of Massachusetts Amherst research.

Almost half (47%) of UK adults are worried that they or their loved ones will have a painful or undignified death, according to a survey commissioned by King's College London.

A new ESC Clinical Consensus Statement published in the European Heart Journal discusses the key role of vaccination in preventing cardiovascular events following various viral and bacterial infections.

Northwestern Medicine investigators have identified a surprising culprit in the progression of inflammatory bowel disease: a naturally occurring metabolic compound in the gut, according to a study published in Nature Immunology.

Depression and anxiety are the most common psychiatric disorders in the world. Around 300 million people suffer from depression, whereas 301 million have anxiety disorder. That's nearly 8% of the global population. Unfortunately, many of these people are prescribed drugs that have no effect when they first visit their doctor. Nearly half of all patients experience no effect of the drugs first given to them, making recovery a lengthy affair, lasting weeks or sometimes months.

Diets rich in phosphate additives, commonly found in processed foods, can increase blood pressure by triggering a brain signaling pathway and overactivating the sympathetic nervous system that regulates cardiovascular function, UT Southwestern researchers discovered. Their findings could lead to treatment strategies for patients with hypertension caused by overconsumption of foods containing high levels of phosphates.

Dr. Jason Kim and Dr. Steven Weissbart of the Women's Pelvic Health and Continence Center at Stony Brook University Hospital (SBUH) have successfully performed one of the nation's first—and the East Coast's very first—Glean Urodynamics procedures using Bright Uro's ambulatory urodynamic system.

Kennedy researchers have uncovered new clues about how immune memory exacerbates inflammation in rheumatoid arthritis, which could lead to better ways to control the disease.

Wavefront shaping is a promising approach to deep tissue imaging. Until now, it was possible only via an invasive approach: fluorescent points were manually inserted into the sample, and the tissue was indirectly mapped by imaging them. That process has many disadvantages, and it was clear that direct imaging of the tissue is a better way.

When Novak Djokovic limped out of the 2024 French Open with a torn meniscus in his knee, all eyes turned to whether he'd be fit for Wimbledon. And when Nick Kyrgios pulled out of Wimbledon for the third year running earlier this month due to a knee injury, fans were disappointed, but medical experts may not have been surprised.

An engineered protein turns off the kind of immune cells most likely to damage tissue as part of type-1 diabetes, hepatitis, multiple sclerosis, shows a new study in mice.

"He hides his smile in every school photo," Jayden's mother told me, holding up a picture of her 6-year-old son.

Because aging weakens cognitive skills, older people can struggle to read difficult social cues. A brain region involved in attention and arousal—the locus coeruleus (LC)—helps with complex tasks, and its connections to the cortex may adapt as humans age to support cognition.

How does the human brain track emotions and support transitions between these emotions? In a new eNeuro paper, Matthew Sachs and colleagues, from Columbia University, used music and an advanced approach for assessing brain activity to shed light on the context dependence and fluctuating nature of emotions.

In a world flooded with fitness fads and "quick-fix" workout plans, solid evidence can often get drowned out. Yet the science is clear: jogging for just five to ten minutes a day can lower your risk of dying from heart disease and even reduce your overall risk of dying from any cause. This kind of research rarely gets the attention it deserves.

Many of us have gotten into the habit of listening to podcasts, audiobooks and other online content at increased playback speeds. For younger people, it might even be the norm. One survey of students in California, for instance, showed that 89% changed the playback speed of online lectures, while there have been numerous articles in the media about how common speedy viewing has become.

Summer is the UK's best-loved season. It's easy to see why, with the warmer, sunnier weather it brings. But the temperature isn't the only reason people prefer midsummer to the dark days of winter. Many also report their mood is better during the warmer months.

A recent study of outcomes in infants and young deaf children with cochlear implants (implanted electronic hearing device), suggests that socioeconomic status (SES) plays a major role in whether spoken language becomes their primary communication mode. The researchers found that communication primarily using spoken language occurred in 85% of commercially insured children with cochlear implants compared to 33% of Medicaid-eligible children. Results were published in the journal Laryngoscope.
