Produce like lettuce and melon is prone to foodborne illnesses if you don’t wash them properly. But harmful bacteria can affect more than fruits and vegetables — they can also thrive on frozen dairy desserts. Here’s how ice cream can cause diarrhea and other gut issues. Causes How Does Melted Ice Cream Cause Diarrhea? Letting a tub of ice cream sit outside the freezer for too long can affect your health. “Ice cream melts fairly rapidly at room temperature, and the milky, sugary, liquid concoction is the perfect petri dish for bacteria like listeria,” Amreen Bashir, PhD , a lecturer…

When we discuss the gut, we’re primarily talking about the small intestine, where 90% of food is absorbed2. The quality of health in the gut is dependent on the microbiota (aka gut flora), which is made up of microscopic organisms (e.g., bacteria, viruses, and fungi) living in the intestines. Healthy gut flora—often called “good bacteria”—help with digestion, support immune function, and are even linked to cognitive function and mood. 

Cell linesB16-F0 (ATCC; CRL-6322) and its LN metastatic derivatives: NBF0-LN1-18IL, NBF0-LN7-1112AR, NBF0-LN7-1120BL, NBF0-LN7-1134BL, NBF0-LN8-1194BR, NBF0-LN8-1198AR, NBF0-LN8-1205BL, NBF0-LN9-1315BL and NBF0-LN9-1358IR—were provided by the Reticker-Flynn Laboratory. For simplicity, these cell lines are referred to throughout the manuscript as: B16-F0, LN1-18IL, LN7-1112AR, LN7-1120BL, LN7-1134BL, LN8-1194BR, LN8-1198AR, LN8-1205BL, LN9-1315BL and LN9-1358IR, respectively. B16F10 wild-type (WT), B16F10 Fsp1-KO and B16F10 Gpx4-KO cells were obtained from the Conrad Laboratory. B16-F0 Fsp1-KO, LN7-1134BL Fsp1-KO, LN9-1315BL Fsp1-KO, B16-F0 Gclc-overexpression, LN7-1134BL Gclc-overexpression, B16-F0 Gclc-KO and B16-F0 Nrf2-overexpression lines were generated in this study.

The draft reference atlases, created by a global consortium of researchers, show how different brain cells are established in different species through neurodevelopment. Outlined in a collection of Nature research papers, they highlight how the expression of genes and identity of cells changes dynamically through development and the cellular processes involved in the creation of different brain cell types. The findings reveal time…

“Because Japan is an island, you can’t do something sketchy because they’ll bust you off the island,” she said. “It’s really a long game, so doing shortcuts really doesn’t work. And so that really results in things like quality, orientation, reputation, reliability, and these are things that I think being an immigrant, we’ve really protected those values.”After two decades at major pharmaceutical and biotech companies, Yamada-Lifton took the helm of her father’s 48-year-old nutritional supplements company in 2023. Her journey was shaped by both parental influences—her father’s entrepreneurial vision and her mother’s emphasis on independence.“So in Japan, they have dynasties,…

Cocktails often contain added sugar, which can have negative health consequences. Evidence is also stacking up against alcohol having health benefits. Limit or avoid alcohol to lower your risk of heart disease, cancer and dementia. If you look forward to relaxing at the end of the day with a cocktail, you’re one of many. According to a 2025 Gallup Poll, 54% of Americans report drinking alcohol at least on occasion. This is down from the 2023 reports of 62% of U.S. adults being imbibers. Experts believe this may be due to more evidence being stacked up against the supposed health…

Prunes have been gaining traction across social and mainstream media this year as a simple way to complement a GLP-1 diet, highlights the California Prune Board. The umbrella group says this visibility is helping introduce new shoppers to the category and reinforces prunes as a “prominent fixture in the snack and baking aisles.” Prunes’ nutrient-dense profile and natural fiber pair well with consumers using weight loss drugs, highlights the board.UK government statistics recently estimated that around 64% of adults are overweight or living with obesity, which is likely to propel GLP-1 medication use, reshaping shopping habits toward healthier, nutrient-rich foods.Esther…

Whether you exercise in the morning or later in the day, research shows both times can help lower blood pressure.The best time to work out is one that fits into your schedule and that you can stick with.Start slow, pick activities that you enjoy and stay consistent to see the greatest benefits. Ever sit in traffic, running late for work and feel your blood pressure rising? Blood pressure naturally fluctuates throughout the day, and factors like stress, emotions, diet—and even exercise—can all influence it. But when it stays high over time, a condition known as hypertension, it can lead to…

New research from scientists at Max Planck Institute for Biology of Ageing, Icahn School of Medicine at Mount Sinai, and their collaborators helps elucidate the neuroprotective role of microglia, the innate immune cells of the brain, and points to a possible therapeutic pathway for Alzheimer’s disease. Details of their work are published in a new Nature paper titled “Lymphoid gene expression supports neuroprotective microglia function.”   Using mouse models and human cells and brain tissue, the scientists found that downregulating the transcription factor PU.1 promotes the expression of lymphoid immunoregulatory receptor proteins on microglia. They also found that deleting CD28 from this…
