Brazilian researchers are advancing a promising cancer immunotherapy by making natural killer (NK) cells more powerful and precise. In a recent study, scientists at the Ribeirão Preto Blood Center and Cell Therapy Center (CTC) used the NK-92 cell line to test a new design of a chimeric antigen receptor (CAR). These engineered receptors contain specific co-stimulatory components such as 2B4 and DAP12 that help activate cells. The study results showed that these additions made the cells “attack-ready” and significantly increased their ability to destroy tumor cells. This research Frontiers of immunology. CAR-based therapies are already transforming the treatment of blood-related…

A new analytical method allows scientists to accurately track where drugs accumulate in living cells for the first time, potentially improving the way cancer treatments are designed. Researchers at the University of Surrey and King’s College London have developed a method to detect trace amounts of metals in individual living cells and their internal compartments without first killing the cells. The study, published in Spectrochimica Acta Part B, looked at a type of cancer treatment called targeted radionuclide therapy. It works by attaching radioactive particles to molecules that seek out tumor cells and delivering radiation directly to the cancer. Where…

China’s competitive education system is known for rigorous assessment, rigorous focus, and academic pressure. Recent research highlights this growing problem of academic pressure that is causing burnout among Chinese adolescents and driving them to online gaming. While previous research has been able to demonstrate a link between academic burnout and behavioral addictions, this study reveals how academic burnout can lead to Internet Gaming Disorder (IGD) and explains how depression and negative attention can have a chain reaction that increases overall risk. To achieve this objective, a research team led by Professor Liping Jia and Professor Guohua Lu from the Department…

In new research to be presented at this year’s European Obesity Conference (May 12-15) in Istanbul, Turkey. nutrition journala 42-year-old theory about why children’s body mass index (BMI) decreases from infancy onwards and then rises continuously from the age of 6 – the ‘obesity rebound’ has been refuted using new analysis – the real reason is proposed to be increased muscle mass, rather than decreased body fat. The study is by Professor Andrew Agbaje, a physician and associate professor of clinical epidemiology and child health at the University of Eastern Finland in Kuopio, Finland. It is important to disprove the…

What is trash to one species is treasure to another. The Pacific Garbage Patch in the Pacific Ocean is now home to dozens of species, and the floating islands of plastic highlight the impact human civilization can have on even the most remote areas. The presence of more species in the open ocean may also facilitate the spread of invasive species.move inThe Great Pacific Garbage Patch is located within the North Pacific Subtropical Gyre, a “giant rotating current system between California and Hawaii,” where “floating objects tend to become trapped rather than drifting away,” Earth.com says. This gyre has effectively…

It has long been known that sleep deprivation weakens the immune system. Now, researchers at the University of Florida Health Cancer Institute have made the surprising discovery that the gut microbiome drives changes in the immune system caused by chronic sleep deprivation. These changes accelerate cancer progression, disrupt circadian rhythms, and make chemotherapy less effective. “Sleep deprivation is extremely common among cancer patients, but is often overlooked in patient care, and there has been a lack of molecular evidence linking it to disease outcomes,” said Maria Hernandez, a graduate student in Dr. Christian Jobim’s lab, who presented the study at…

Scientists have discovered how a naturally occurring hormone can reverse obesity in mice. The answer lies in the brain. Researchers at the University of Oklahoma have discovered that this hormone works by sending signals to areas of the brain that help control metabolism and appetite. This is the same general area targeted by widely used GLP-1 weight loss drugs. The research results were published in a magazine cell report. This hormone, known as FGF21 (fibroblast growth factor 21), has already attracted attention as a potential target for new treatments. Drugs designed to act on this pathway are currently being tested…

As people age, their blood and immunity gradually decline. The main reason is a decline in hematopoietic stem cells (HSCs), which are responsible for producing all types of blood cells. In a healthy state, these stem cells can regenerate themselves and create a balanced mix of blood cells. However, over time, their efficiency decreases. They produce fewer new cells, prefer certain types of cells such as myeloid cells over lymphoid cells, and are less able to support a strong immune response. Several factors may cause this decline, including accumulation of cellular damage, changes in gene activity, chronic low-level inflammation, and…

AI is no longer just a support tool in drug development. This paper shows how it can help build faster, smarter, and more personalized cancer treatments, while also highlighting the scientific and regulatory hurdles that still stand.

Widely used free AI chatbots can sound confident while offering misleading health information, weak quotes, and advice that may be unsafe without expert guidance, according to a new audit. Research: Generative artificial intelligence-driven chatbots and medical misinformation: An audit of accuracy, referentiality, and readability. Image credit: Bankiras / Shutterstock In a recent study published in the journal BMJ Openresearchers audited the accuracy, referability, and readability of five popular artificial intelligence (AI)-driven chatbots to investigate how they responded to health questions in a field rich in misinformation. The study utilized 250 prompts across five misinformation-prone categories, and the output was evaluated…
