MIT scientists have identified cysteine — an amino acid found in foods like meat, dairy, beans, and nuts — as a potent trigger for intestinal repair. In mice, a cysteine-rich diet activated immune cells that released healing signals, helping ...
Scientists have identified a protein that appears to put the brakes on the chronic inflammation linked to aging. Older mice with boosted levels of the protein were stronger, more energetic, and had healthier bones than untreated mice. Researchers ...
A huge long-term study found that drinking two to three cups of coffee a day was linked to a much lower risk of dementia, especially before age 75. Researchers say caffeine may help keep brain cells active while reducing inflammation and harmful ...
As blood stem cells age, their lysosomes become overactive and damaged, triggering inflammation and weakening the body’s ability to regenerate healthy blood and immune cells. By calming this ...
Scientists have developed a breakthrough injectable biomaterial that travels through the bloodstream to repair damaged tissue from within, reducing inflammation and jumpstarting healing. In animal studies, it successfully treated heart attack damage ...
The body’s “killer” T cells don’t just attack—they strike with astonishing precision, forming a tiny, highly organized contact zone that lets them destroy dangerous cells without harming their neighbors. Now, scientists have captured this ...
A gut bacterium may be quietly fueling depression through an unexpected chemical twist. Researchers found that when Morganella morganii interacts with a common pollutant, it produces a molecule that ...
A common eye-health nutrient, zeaxanthin, may also help the body fight cancer more effectively. Scientists discovered it strengthens T cells and enhances the impact of immunotherapy treatments. Found in everyday vegetables and supplements, it’s ...
Chronic inflammation often works quietly in the background but can fuel serious diseases like diabetes, heart disease, and cancer. New research reveals that everyday plant compounds—like menthol from mint, cineole from eucalyptus, and capsaicin ...
A new clinical trial suggests that what people eat could finally offer real relief for Crohn’s disease, a condition that has long lacked clear dietary guidance. Researchers found that a “fasting-mimicking diet” — involving just five days a ...
A new study reveals that high doses of antioxidants—often seen as harmless or beneficial—may actually impact future generations. Male mice given common supplements like NAC produced offspring with subtle but significant facial and skull changes. ...
Your morning coffee or tea could be quietly supporting your brain health. A long-term study found that moderate consumption of caffeinated coffee or tea was linked to an 18% lower risk of dementia and better cognitive performance over time. The ...

A newly uncovered immune chain reaction in the gut may explain why people with inflammatory bowel disease face a much higher risk of colorectal cancer. Researchers found that a powerful inflammatory ...

Scientists are taking a closer look at monk fruit and discovering it’s more than just a sugar substitute. New research shows its peel and pulp contain a rich mix of antioxidants and bioactive ...

Researchers have found a reliable way to grow helper T cells from stem cells, solving a major challenge in immune-based cancer therapy. Helper T cells act as the immune system’s coordinators, ...

Researchers have developed a new class of antibodies that amplify the immune system’s ability to fight cancer. By clustering immune receptors that normally receive weak signals from tumors, these ...

A vitamin A byproduct has been found to quietly disarm the immune system, allowing tumors to evade attack and weakening cancer vaccines. Scientists have now developed a drug that shuts down this ...

Scientists have found that combining silybin with carvedilol works far better against liver fibrosis than either drug alone. The duo targets the root drivers of liver scarring, sharply reducing ...

Long COVID affects an estimated 65 million people worldwide and can damage the brain, heart, blood vessels, and immune system long after infection. Researchers now link symptoms to lingering virus, ...

As the immune system weakens with age, scientists have found a way to restore some of its lost strength. By delivering mRNA to the liver, they created a temporary source of immune-boosting signals ...

Aging immune cells may be sabotaging the body from within. Researchers found that macrophages produce a protein that locks them into a chronic inflammatory state, making infections like sepsis more ...

Stanford scientists have uncovered how mRNA COVID-19 vaccines can very rarely trigger heart inflammation in young men — and how that risk might be reduced. They found that the vaccines can spark a ...

Natural killer cells act as the immune system’s rapid-response team, but the stress of anxiety and insomnia may be quietly thinning their ranks. A study of young women in Saudi Arabia found that ...

A decade-long study of older women found that tea drinkers had slightly stronger bones, while moderate coffee drinking caused no harm. Heavy coffee intake—over five cups a day—was linked to lower ...

A cutting-edge therapy using base-edited immune cells is offering a major breakthrough for patients with one of the toughest forms of blood cancer, T-cell acute lymphoblastic leukaemia. By precisely ...

Drinking tea, particularly green tea, is linked to better heart health, improved metabolism, and lower risks of chronic diseases like diabetes and cancer. It may also help protect the brain and ...

Scientists studying young adults with obesity discovered early indicators of brain stress that resemble patterns seen in cognitive impairment. The group showed higher inflammation, signs of liver ...

A new nasal-delivered nanotherapy shows promise against aggressive glioblastoma tumors. By activating the STING immune pathway using gold-core spherical nucleic acids, researchers were able to reach ...

Researchers at Stanford found a way to cure or prevent Type 1 diabetes in mice using a combined blood stem cell and islet cell transplant. The procedure creates a hybrid immune system that stops ...

Researchers discovered that chronic inflammation fundamentally remodels the bone marrow, allowing mutated stem cell clones to quietly gain dominance with age. Reprogrammed stromal cells and ...

Chronic pain might quietly push people toward developing high blood pressure—and the more widespread the pain, the greater the danger. A massive analysis of over 200,000 adults uncovered strong ...

Scientists have uncovered how too much sunlight can flip a hidden switch inside skin cells that makes inflammation spiral out of control and increases the risk of cancer. Their research reveals that ...
