Sanofi’s protein-based vaccine, Nuvaxovid, defeated Moderna’s next-generation messenger RNA shot, mNexspike, in a head-to-head trial evaluating the tolerability of two coronavirus vaccines. In a Phase 4, double-blind, real-world study of 1,000 adult participants in the United States, Nuvaxovid was shown to have statistically significantly fewer side effects across all prespecified endpoints. Symptomatic reactions with Nuvaxovid were milder and shorter-lived than with mNexspike. Additionally, less than 10% of people who received Nubaxovid experienced severe side effects that interfered with their daily life, such as fatigue, headache, and fever, compared to less than 20% of people who received mNexspike. Injection site symptoms…
Researchers at the University of Lausanne (Unil) have discovered a new biological mechanism by which vitamin B7 deficiency exposes critical vulnerabilities in tumor cells. すべての細胞は、生き残るために栄養供給の変化に適応する必要があります。 However, some cells become particularly dependent on glutamine, an amino acid that plays a major role in metabolism. Glutamine provides an essential component needed for the construction of proteins and DNA, and without it cells cannot continue to grow and divide. Cancer cells are a typical example. Many tumors exhibit what scientists call “glutamine toxicity,” meaning they are highly dependent on this nutrient.この依存性は弱点と考えられていますが、多くのがんはそれを回避する方法を見つけています。 In a study published in a journal molecular cellA team led by…
The idea that fruits and vegetables can cause cancer sounds strange. Decades of research has shown that people who eat more plants tend to live longer and healthier lives and have lower rates of heart disease, stroke, and some common cancers. Lung cancer is no exception. Many large studies have found that higher fruit and vegetable intake is associated with lower risk, especially for smokers. Against this backdrop, the new suggestion that fruits and vegetables may be contributing to lung cancer in young people is surprising. The story behind this latest wave of unrest does not emerge from a definitive…
Researchers at the University of Eastern Finland have identified new geometric markers in the ventricles that may help predict which patients with idiopathic normal pressure hydrocephalus (iNPH) will benefit from shunt surgery, according to a recent study published in 2008. Central nervous system fluids and barriers. iNPH is a likely underdiagnosed disease in older adults characterized by abnormal gait, urinary urgency and incontinence, and decline in cognitive function. Unlike most dementias, iNPH stands out because symptoms often improve or reverse with timely shunt surgery. Neuroimaging is essential for the diagnosis of iNPH. However, current diagnostic markers are limited and cannot…
Pleural fluid cytology is already used in the diagnosis of cancer, especially metastatic disease, but its sensitivity may be limited. Tumor cells are easily obscured by the overwhelming number of background blood cells, and the cluster structure may be disrupted during processing. Although immunoaffinity approaches can detect malignant tumor cells (MTCCs), they may damage cells, dissociate malignant tumor cell clusters (MTCCs), or mask surface biomarkers with bound antibodies. Existing label-free microfluidic systems also face persistent trade-offs between throughput, purity, gentle handling, and the ability to separate single cells from clusters within the same platform. Based on these challenges, detailed studies…
UPV’s research team is leading the development of sensors that pave the way for rapid, selective and cost-effective detection of active tuberculosis. The device detects the presence of a protein secreted by the disease-causing Mycobacterium tuberculosis. Get results in just 60 minutes. This is significantly faster than traditional methods, such as microbial culture, which take several weeks. Tuberculosis remains one of the world’s major public health problems today. According to the World Health Organization’s 2024 Global Report, it is the number one cause of death from a single infectious pathogen. “Having tools that allow early and reliable diagnosis is therefore…
Democrats should be more vocal about clean energy affordability and resilience from global shocks, according to some of the party’s leading voices on climate change.Countries aim to accelerate their transition to clean energy as the Iran war raises oil and gas prices and disrupts economies. But in the United States, where President Donald Trump is seeking to destroy all energy alternatives to fossil fuels, his Democratic opponents are reluctant to link the conflict to any action on the climate crisis.The closure of the Strait of Hormuz, through which a fifth of the world’s oil and gas normally passes, has caused…
Recent research published in Journal of Sex and Couple Therapy Our findings suggest that men who identify as involuntarily celibate consume more pornography and experience more body dissatisfaction than other men. This study provides evidence that frequent use of adult media, combined with the belief that women expect men to look like porn actors, tends to worsen men’s views of their bodies. Involuntary celibates, commonly known as incels, are men who deeply desire a romantic or sexual relationship but find it simply impossible to achieve it. This group tends to form a specific online identity centered around rigid and fatalistic…
A new kind of political threat may be emerging, but it is far less visible than protests or traditional vote manipulation. Researchers warn that highly realistic personas controlled by AI could soon play a major role in shaping public opinion and influencing democratic systems. Recent policy forum papers published in science We explain how a large group of AI-generated personas can convincingly imitate human behavior online. These systems can enter digital communities, participate in discussions, and influence perspectives at incredible speed. Unlike previous bot networks, these AI agents can adjust on the fly, respond to feedback, and maintain a consistent…
