Recent research published in journals psychophysiology When a person is not confident in their performance and yet tries to brag about it, it suggests that their body is still showing subtle signs of lying. This study provides evidence that uncertainty drives individuals to a middle ground between honesty and deception. This middle ground allows individuals to increase their self-esteem while being less physiologically stressful than outright lies. Humans often navigate complex social situations by deciding whether to be honest or bend the truth for personal gain. Telling an obvious lie usually causes physical changes, such as increased sweating, whereas being…
Sexually transmitted infections (STIs) not only affect the health of individuals, but also result in billions of dollars in economic losses worldwide. To study these diseases, a team of researchers developed a first-of-its-kind immune-enabled “organ-on-a-chip” model that realistically recreates the human cervical environment. This allows scientists to study how the microbiome, immune system, and sexually transmitted diseases interact. This has not been possible until now with overly simplistic cell culture and animal models. Scientists from the University of Maryland School of Medicine (UMSOM) and School of Dentistry (UMSOD), the University of Delaware, and the University of Virginia published the study…
Biomedical researchers have designed an injectable microgel to reduce bleeding in infants requiring surgical treatment. In animal models, engineered microgels reduced bleeding by at least 50%. When adults cut themselves, a multistep process called hemostasis stops bleeding from the injured blood vessels. However, hemostasis in infants is different from hemostasis in adults. This difference can be problematic if the infant requires surgery to address a serious medical problem. During surgery, patients usually receive blood from an adult donor to replace blood lost during surgery. However, when adult blood is given to an infant, the difference between adult and infant…
The Global Virus Network (GVN), which represents renowned human and animal virologists from more than 90 centers of excellence and affiliates in more than 40 countries dedicated to advancing research, collaboration, and pandemic preparedness, is monitoring the SARS-CoV-2 variant BA.3.2, sometimes informally referred to as the “semi” variant in media reports, and stresses that current evidence does not indicate a cause for alarm or heightened public concern. BA.3.2 is a sublineage of the Omicron variant of SARS-CoV-2 that is being tracked through the global genomic surveillance system. Initial analysis, including technical assessments by international public health authorities and new clinical…
Pancreatic ductal adenocarcinoma is the most common type of pancreatic cancer and has a poor 5-year survival rate. It begins with a reversible condition called acinar-to-ductal metaplasia, in which cells can heal after injury or inflammation. If a cancer-causing mutation is present, metaplasia can continue to progress toward cancer. In a new study published in natural metabolism, Researchers have identified cellular pathways that may influence metabolic changes as cells progress from metaplasia to cancer. Their results could help researchers treat benign lesions before they become tumors. “We know a lot about how pancreatic tumors behave and look, but we don’t…
It is safe for patients to receive donor livers that are intentionally preserved overnight using machine perfusion to allow daytime transplantation. This is shown by a study conducted at the University Medical Center Groningen (UMCG) in the Netherlands that involved transplants using all types of donor organs. Outcomes after transplantation are at least as good as those of livers that were not treated with machine perfusion or treated for only a short period of time before transplantation. Analysis of all liver transplants over 2 years Machine perfusion techniques developed at UMCG have previously been shown to allow liver transplants to…
Children who live within 7 miles of the Salton Sea, a dry body of water with high levels of salt and pollutants in California’s Imperial Valley, have slower growth in lung function between the ages of 10 and 12 than children who live further away. This effect is comparable to living within 500 meters of a highway and can affect respiratory health well into adulthood. The study was funded in part by the National Institutes of Health and was just published in the journal Science. JAMA network open. The Salton Sea is a salt lake near the U.S.-Mexico border that…
What does a “fair” partnership look like between hospitals and AI developers? As hospital workflows, clinician expertise, and rich clinical data increasingly drive the performance and market value of vendors’ AI tools, providers face important questions. It’s about how we can share the benefits while protecting patients, maintaining trust, and avoiding new forms of liability. This article examines new models for data sharing, governance, and value capture, providing health systems with a practical framework to ensure they benefit from data-driven innovation. Hospitals introducing AI In recent years, more hospitals have developed and licensed AI tools to reduce clinician burnout, improve…
Although young children’s exposure to cigarettes is decreasing, electronic nicotine products are exposing young children to new risks of inhalation, Rutgers Health researchers say. Their research is JAMA network openwas the first to assess trends in infant nicotine exposure across all types of products. Researchers at the New Jersey Poison Control Center, based at Rutgers New Jersey Medical School, used the National Poison Data System to analyze more than 92,000 nicotine exposures in children under 5 years of age reported between 2016 and 2023 to understand how the rise of new products, particularly disposable e-cigarettes and nicotine pouches, has changed…
How is Jannik Sinner able to hit the ball at exactly the right time and with incredible precision? And how do we perceive the duration of events around us in everyday life? The answer lies in how the brain constructs our perception of time, as shown in a study published in PLOS Biology by Valeria Centanino, Gianfranco Fortunato, and Domenica Buetti. Starting with what we see, such as the approach of a ball, temporal information is processed by the brain through progressively more complex stages: occipital visual cortex, parietal and premotor areas, and finally frontal areas. By using high-field functional…
