From endothelial function to blood pressure, this review maps where bioactive compounds in blueberries and grapes hold promise and where clinical evidence is still lacking. Study: Polyphenols and cardiovascular health: Emerging associations with blueberries, grapes, and red-fleshed table grapes. Image credit: Den Debono / Shutterstock Recent reviews published in magazines nutrients investigated the evidence regarding the effects of blueberries, grapes, and their bioactive compounds on cardiovascular risk markers. Cardiovascular disease (CVD) is one of the most prevalent non-communicable diseases and a leading cause of death in Europe. The paper reports that more than 60 million years of life are potentially…
A cross-species review tracks how iodine affects immune defense and why the line between benefit and harm remains difficult to define. Article: Iodine and its effects on the immune system of humans and domestic mammals: A narrative review In a recent narrative review published in the journal nutrientsResearchers from the University of Guelph and Canada’s Immunoseutica have mapped the direct and indirect immunomodulatory mechanisms of iodine in humans and domestic mammals. Although this review suggests that iodine status follows a narrow U-shaped relationship and that an appropriate intake range supports leukocyte metabolism, tissue antioxidant capacity, and thyroid hormone-mediated immune responses,…
A plant-based diet is good for you. They promote gut, immune, metabolic, and cardiovascular health by cultivating a diverse community of gut bacteria. It has long been known that some of these benefits come from the fiber in plant-based foods that is processed by our commensal gut bacteria and the often brightly colored “phytochemicals” that plants produce to protect themselves from environmental threats. However, much remains unknown about how the bugs in our stomachs process the components of vegetables to produce these health benefits. A pair of studies led by Ludwig Princeton University’s Jenna Absalim and director Joshua Rabinowitz, one…
Our brain requires more energy than other organs. However, even when energy supplies are scarce, information processing can be performed flexibly using what is available. How the brain resourcefully allocates this limited energy across internal states remains an important question in neuroscience. Sleep is an effective way to answer this question. Although sleep involves rest, the brain is still active. This is especially true during rapid eye movement (REM) sleep, a stage closely associated with dreams and memory processing. REM sleep is sometimes called “paradoxical sleep” because the body is mostly still while the brain exhibits wake-like activity. Researchers at…
A new multicenter clinical study highlights a potential new approach for patients with advanced kidney cancer, providing a clearer picture of how the disease works beneath the surface and providing measurable clinical responses. Results from the ARC-20 Phase 1 clinical trial show that Kasdatifan, an oral investigational therapy designed to inhibit hypoxia-inducible factor 2α, produced durable tumor responses with a manageable safety profile in patients with heavily pretreated clear cell renal cell carcinoma, the most common form of kidney cancer. This study nature. For a disease that often adapts and resists treatment, the results provide an early signal that a…
Everyday conversations with romantic partners are deeply influenced by underlying relationship dynamics, such as uncertainty and mutual support. Recent research has found that there are differences in how men and women respond to these underlying power relations, with men’s doubts about the relationship predicting a negative emotional and communicative tone for both partners. The study was published in the journal Communication Research. Romantic relationships naturally involve the merging of everyday life and personal goals. As partners become more involved in each other’s lives, they may help or hinder each other’s daily activities. Researchers refer to the perception that a partner…
Recent research published in journals biochemistry and cell biology Studies suggest that psilocybin, an active compound found in certain mushrooms, may help protect skin cells from premature aging caused by poor diet. The results of this study provide evidence that psilocybin reduces inflammation and cellular stress in skin cells exposed to high levels of sugar and fat. Skin aging is a complex biological process influenced by a combination of genetic and environmental factors. Diets rich in sugar and fat are known to increase oxidative stress throughout the body and accelerate this process. Oxidative stress occurs when harmful highly reactive oxygen…
Archaeologists have identified a prehistoric hammer made from elephant bone that dates back about 500,000 years. The object, discovered in southern England, is the oldest elephant bone tool ever discovered in Europe. Researchers from UCL and the Natural History Museum have analyzed rare artifacts that provide an astonishing demonstration of the intelligence and technological capabilities of our early human ancestors. Their discovery is scientific progress. This tool was probably an early Neanderthal. A man from Heidelberg. Rather than functioning as a heavy hammer, it served as a softer striking tool used to repair or sharpen stone hatchets and other bladed…
When adults are dissatisfied with their romantic relationships, they are more likely to tolerate cheating. This psychological connection is highly influenced by a person’s basic willingness to participate in a casual sexual encounter. These findings were recently published in the journal Sexual and Relationship Therapy. Romantic relationships require a continuous investment of time and emotional energy. Psychologists often use the investment model of commitment to understand why people remain loyal to their pairings. This model suggests that satisfaction, the pure quality of the relationship, and the attractiveness of alternative partners all interact to determine a person’s loyalty. Unmet needs in…
Why do some dreams feel so vivid that they seem real, while others unfold in disorganized fragments that are difficult to remember or understand? New research suggests the answer may depend on a combination of personality, sleep quality, mental habits, and big events happening in the outside world. A study led by researchers at the IMT School of Advanced Studies in Lucca found that dreams are more than just random collections of images and thoughts. Rather, they appear to be shaped by both individual differences and common experiences, including major social disruptions such as the COVID-19 pandemic. Thousands of dream…
