The FDA reprimanded Bayer for “attention-grabbing visuals” and “frequent scene changes” in ads for its prostate cancer drug Nubeca. FDA officials expressed their concerns in an untitled letter (PDF) after reviewing a direct-to-consumer (DTC) YouTube video and Nubeka’s Spanish-language television ads. The FDA ruled that Bayer’s promotional materials were false or misleading because they claimed the benefits of Nubeka but omitted risk information about the drug. Bayer included a statement saying, “Nubeka can cause serious side effects, including heart disease and seizures.” However, the FDA flagged additional details that were included in the patient information but not included in the…

Psychologists have long debated whether the human mind can be explained by a single unifying theory, or whether different functions such as attention and memory need to be studied separately. Now, artificial intelligence (AI) is entering that discussion, offering new ways to explore how the mind works. In July 2025, a study was published in July 2025. nature We introduced an AI model called “Centaur”. Built on standard large-scale language models and refined using data from psychology experiments, Centaur was designed to simulate human cognitive behavior. It reportedly performed well across 160 tasks including decision-making, business management, and other mental…

Recent psychological research suggests that gold digging is not simply a gender-based stereotype, but rather a calculated social strategy associated with traits such as psychopathy and narcissism. This finding provides evidence that people who engage in this behavior are willing to sacrifice emotional intimacy in order to extract economic resources from their partners. This study was published in the journal personality and individual differences. Scientists Lennart Fries and Peter K. Jonasson designed this study to understand the psychological motivations behind highly materialistic dating behavior. Freyth is affiliated with the Institute of Behavioral and Social Sciences in Austria and the HSD…

Alzheimer’s disease is often described in numbers: it affects millions of people, the number of cases is rapidly increasing, and the costs reach trillions of dollars. But for families, the experience is deeply personal. “It’s a slow bereavement,” says Cold Spring Harbor Laboratory professor Nicholas Tonks, whose mother has Alzheimer’s disease. “You lose that person little by little.” A major focus of Alzheimer’s disease research is plaque buildup in the brain. These plaques are composed of amyloid beta (Aβ), a naturally formed peptide that can accumulate and cluster over time. These deposits are widely believed to play an important role…

Daily intake of ultra-processed foods 5% increased risk of stroke, heart attack, or cardiac arrest. This is the stark finding of a study published last month in the Journal of the American College of Cardiology, the latest study to show a link between industrially produced foods and health problems such as diabetes, heart disease and obesity. From breakfast cereals to chicken nuggets to candy bars, ultra-processed foods are mass-produced products that contain ingredients such as preservatives, emulsifiers, and other additives not found in home kitchens.Although some countries have adopted policies aimed at reducing the consumption of ultra-processed foods, the root…

Although BMI has its limitations, it is currently the metric that medicine often defaults to when predicting weight-related health problems. The new tool is expected to more accurately define who is at risk of obesity complications, based not only on BMI but also on measures such as family history, diet, current illnesses and socio-economic factors extracted from medical records. One of the goals of this study is to better understand candidates for obesity drugs, which are often prescribed based on BMI alone or in combination with BMI and another disease. The initial target was type 2 diabetes, but over time…

A large trial conducted at community health centers in the United States shows that mailed FIT-DNA kits outperform FIT in facilitating colorectal cancer screening. Nevertheless, fewer than 4 in 10 patients with abnormal results complete a follow-up colonoscopy. Study: Mailed Outreach for Colorectal Cancer Screening in Community Health Centers. Image credit: Orawan Pattarawimonchai/Shutterstock.com Fecal immunochemical testing-DNA may be a more effective mail outreach approach than fecal immunochemical testing to increase colorectal cancer screening rates among adults receiving primary care at community health centers, reports a new study published in 2016. JAMA Internal Medicine. Colon cancer screening gaps persist in underserved…

A child’s early exposure can leave a lasting biological mark. This study shows how tiny layers in baby teeth can identify when metals can affect brain development and behavior years later. Research: Changes in brain function related to fetal and postnatal metal metabolism are associated with behavioral disorders in childhood. Image credit: Onjira Leibe/Shutterstock.com A new study using deciduous dental biomarkers to track metal exposure throughout fetal and early infancy has identified a critical period in early neurodevelopment where such exposure is associated with long-term differences in behavior and brain measures observed in late childhood and adolescence. The study was…

Cytotoxic T-lymphocytes act as specialized “killer” cells of the immune system, seeking out and eliminating infected and cancerous cells with remarkable precision. Its effectiveness relies on tightly controlled contact points called “immune synapses,” where it releases toxic molecules that destroy targets while keeping surrounding healthy cells intact. Until recently, scientists have struggled to observe the fine structure of this process in detail. Now, researchers from the University of Geneva (UNIGE) and Lausanne University Hospital (CHUV) have succeeded in visualizing these mechanisms in three dimensions under near-natural conditions. Their findings were; cell reportshed new light on how the internal organization of…

Scent shapes how we experience the world every day. It helps detect danger, adds depth to flavor, and is strongly associated with memories and emotions. Despite its importance, scientists have struggled to fully understand how this sense works at a biological level. “The sense of smell is very mysterious,” says Sandeep (Robert) Dutta, a professor of neurobiology at Harvard Medical School’s Blavatnik Institute. Compared to vision, hearing, and touch, the basic biology of smell remains poorly understood. Scientists create first detailed map of odor receptors In a new study in mice, Dutta and his colleagues have created the first detailed…
