Researchers travelled to northern Alaska to collect samples of tissue from the whales (Balaena mysticetus) from Iñupiaq Inuit communities. The team found that the whale’s…

If you are taking anticoagulant medications (also known as blood thinners) for a health condition, you may need to monitor your intake of Vitamin K-rich foods. Vitamin K plays an essential role in the chemical process of forming blood clots in your body, according to MedlinePlus.This matters because what you eat and drink has the potential to affect how your medication works. Too much Vitamin K could interfere with your treatment plan and make your medications ineffective, which may lead to unintended consequences for your health.What Is Vitamin K?Whenever you are injured, whether it is a paper cut or a…

Credit: BlackJack3D / E+ / Getty Images Repetitive brain injury has the focus of many studies due to the long-lasting effects and the high risk for injury in participants of high impact sports. While there are many neurodegenerative consequences of these injuries, cellular and genetic consequences are not well understood. “Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease linked to exposure to repetitive head impacts (RHI), yet little is known about its pathogenesis,” wrote the authors of a new study published in Science. Both CTE and RHI can cause brain injury, but they are physiologically distinct, with CTE often presenting…

Studying obesity-associated genes from people of non-European ancestry led to the identification of new obesity genes, highlighting the importance of representative samples in gene studies.Image credit:Deepro Banerjee, Girirajan Laboratory, Penn StateWorldwide, more than one billion people are estimated to live with obesity, which increases a person’s risk for cardiovascular disease and other health conditions. Obesity, defined as having a body mass index (BMI) of 30 or greater, has both genetic and lifestyle risk factors. Researchers have identified multiple genes and genetic variations associated with obesity risk, but many of these studies investigated populations of people with predominantly European ancestry. This…

SNAP benefits are set to run out on November 1, assuming the government does not reopen before the weekend. Though a federal judge in Rhode Island has ordered that the government use SNAP emergency funds to pay out those benefits, it’s not clear when those…

A long criticised study on antidepressant use in adolescents has been flagged with an “expression of concern” by a leading academic journal after the launch of legal action.12George Murgatroyd III, a lawyer, is suing the publishing giant Elsevier, as well as the American Academy of Child and Adolescent Psychiatry, demanding the retraction of the 24 year old randomised trial.3Concerns about the widely cited article—including numerous demands for retraction456—have been circulating for almost as long as the paper itself, and the trial, known as Study 329, is regularly referred to as one of the best examples of spin, misreporting, and ghostwriting…

New research suggests that eating flavanol-rich foods like tea, berries, or cocoa may protect men’s vascular health from the adverse effects of prolonged sitting. Participants who drank a high-flavanol cocoa drink before sitting for two hours did not experience flow-mediated dilatation, which measures the elasticity of the arteries. However, men drinking a low-flavanol drink did experience this decline. The authors point to earlier research that a 1% reduction in vascular function, as measured by flow-mediated dilatation, leads to a 13% increased risk of cardiovascular diseases like heart disease, strokes, and heart attacks. “Our research shows that consuming high-flavanol foods and drinks…

Despite fiber’s many benefits, around 95% of adults fall short of the daily fiber recommendations.Eating fiber helps support blood sugar by slowing sugar absorption, feeding beneficial bacteria and supporting steady release of energy.Aim to eat fiber-rich plants at every meal and snack, exercise regularly, prioritize quality sleep and stay hydrated. Most people think of fiber as something that simply keeps you regular, but its benefits extend far beyond digestion. This often-overlooked nutrient plays a surprisingly powerful role in overall health—impacting everything from energy and appetite to long-term metabolic health. One of fiber’s most important functions is helping to regulate blood…
