Antibiotic resistance is becoming one of the most serious dangers facing modern medicine. As bacteria evolve, drugs that were once reliably effective may no longer be effective. This can make common infections more difficult to treat and increase the risks associated with routine surgeries, cancer treatments, and other medical procedures. Researchers around the world are looking for ways to stay ahead of these rapidly changing microorganisms. One promising strategy is to make existing drugs work again, rather than inventing entirely new antibiotics. This is the idea behind antibiotic adjuvants, companion molecules that restore the power of antibiotics rather than directly…

Going to religious services every week will not prevent common mental illnesses or improve your overall psychological health. A recent analysis of long-term data suggests that the previously reported health benefits of gathering for worship may be the result of a combination of life circumstances rather than a true medical benefit. The findings show that the act of attending religious services alone does not provide direct protection against mental illness. The study was published in The Psychology of Religion and Spirituality. For decades, a vast body of literature has suggested a strong association between religious attendance and positive mental health…

Lidar technology uses pulses of infrared light to calculate distance and create a detailed 3D map of the surrounding environment. This allows self-driving cars to detect objects in their path and respond quickly. However, traditional LIDAR sensors are often large and expensive, and many rely on moving components that wear out over time. These limitations make the system difficult to use in a wide range of settings. MIT researchers have now developed an approach that could lead to smaller, more durable LIDAR sensors that operate without moving parts. Their advances focus on new silicon photonics chips, a type of semiconductor…

Recent research published in intelligence and cognitive ability It suggests that certain mental skills, such as technical knowledge, mathematics, and language skills, play an important role in predicting a person’s future income, educational attainment, and career path. This study provides evidence that these specific cognitive abilities are at least one-third more important than general intelligence in shaping a person’s social and economic position. This means education and career guidance programs can benefit from going beyond their overall intelligence scores to help people find paths that suit their unique strengths. Tobias Edwards, a postdoctoral fellow in behavioral genetics and individual differences…

New research suggests doctors may be able to improve cure rates by changing treatments before tumors recover. Rather than waiting for the cancer to come back after the first treatment, researchers suggest switching to another treatment while the tumor is still shrinking. This strategy is designed to address one of the biggest obstacles in cancer treatment: drug resistance. Reasons why cancer is likely to recur Dr Robert Noble, a senior lecturer in the School of Mathematics at St George’s, University of London, led the research. “Tumors may initially shrink with treatment, but they often regrow eventually. These recurrences are because…

Researchers at Seoul National University and Seoul National University have developed a programmable photonic integrated circuit that can slow down light whenever needed. The team was led by Professors Namkyoo Park and Seung-gyu Yu from the School of Electrical and Computer Engineering at Seoul National University, and collaborated with Professor Xiangji Piao from the School of Electrical and Computer Engineering at Seoul National University. Slowing down light could help solve computing bottlenecks The rapid growth of generative AI and large-scale AI models has sharply increased the amount of computing power required in data centers and servers. Traditional electronic semiconductors struggle…

A large-scale multi-omics study maps why the epigenetic clock captures different aspects of aging and shows how gene expression scores sharpen the interpretation. Research: How the epigenetic clock ticks: Unpacking the black box by deciphering the biological pathways and transcriptomic signatures of accelerated aging. Image credit: Lightspring / Shutterstock In a recent study published in the journal npj agingA group of researchers identified biological pathways and gene expression signatures associated with the widely used epigenetic clock and assessed how the Transcriptome Aging Gene Score (TAGS) is associated with aging-related health outcomes. background Why do some people remain healthier than others…

A single dose of psilocybin, the psychedelic substance found in magic mushrooms, causes physical changes in the brain that can remain detectable for up to a month, according to researchers at the University of California, San Francisco and Imperial College London. This study nature communicationshealthy adults who had never used psychedelics participated. Although none of the participants had been diagnosed with a mental health condition, the findings may provide clues as to why psilocybin showed promise in treating depression, anxiety, and addiction. The researchers focused on temporary increases in the brain’s “entropy,” a term that describes the diversity and unpredictability…

The American College of Cardiology (ACC) is introducing a new cardiogenic shock designation to improve outcomes for one of the most life-threatening complications of heart attack. This new designation builds on the success of the existing ACC Chest Pain Center designation, which has helped hospitals standardize and improve care for patients presenting with heart attack symptoms, but previously did not address cardiogenic shock. Additionally, new grants supported by Johnson & Johnson will help rural hospitals implement the designation. Cardiogenic shock occurs when the heart suddenly cannot pump enough blood to meet the body’s needs and remains the leading cause of…

A study published online in an open access journal found that certain imbalances and disruptions in the oral microbiome are associated with symptomatic hand arthritis. RMD open. The findings suggest that the oral microbial environment may influence the disease process of hand arthritis, which is associated with pain, stiffness, and decreased grip strength and can significantly impair quality of life. The oral microbiome is involved in systemic inflammation and interacts closely with the gut microbiome, which is highly associated with symptomatic hand arthritis. To assess the role of the oral microbiome, saliva samples from 52 individuals with symptomatic hand arthritis…
