A new study from Michigan State University challenges the common assumption that narcissists gradually damage relationships over time. The study used longitudinal data to follow more than 5,000 couples for up to six years. Participants completed a questionnaire measuring two aspects of narcissism: narcissistic admiration and narcissistic competitiveness. Narcissists have two different ways of maintaining an exaggerated positive self-perception. They may exaggerate themselves to impress others (narcissistic admiration) or put others down to show that they are better than them (narcissistic competitiveness). ” Gwendolyn Seedman, lead author of the study and associate professor in the MSU Department of…

In a new study to be presented at this year’s European Congress on Obesity (ECO2026) in Istanbul, Turkey (12-15 May), researchers show that low birth weight infants have an increased risk of stroke in young adulthood, independent of body mass index (BMI) as young adults and gestational age at birth. A study of about 800,000 people in Sweden suggests that low birth weight may be included in stroke risk assessment in adults, say the authors, including Dr. Lina Lilja and Dr. Maria Vigdel from the University of Gothenburg in Sweden. Although overall stroke incidence has declined over the past few…

People of color who are also members of sexual and sexual minority groups face unique challenges shaped by overlapping forms of discrimination. While much research has focused on the mental health risks they experience, far less has investigated how people with these multiple identities build strength and resilience. A new study by Aldo Barita of Michigan State University’s Department of Psychology fills that gap. The study, published in the journal American Psychologist, found that affirming one’s identity can be a source of psychological strength, not just vulnerability. Using a national sample of 418 sexually and gender diverse people of color,…

Myotonic dystrophy type 1 (DM1) is the most common cause of adult-onset muscular dystrophy. Muscular dystrophy is a genetic disease that causes muscle weakness and wasting, but also affects the brain, gastrointestinal tract, and heart. In a study published in Journal of Clinical Research Insights, Researchers at Baylor College of Medicine focused on the effects of DM1 on the heart. Their findings help answer questions about why the disease worsens over time and whether the damage once set can be reversed. Cardiac symptoms affect most DM1 patients. Heart problems are primarily electrical conduction abnormalities, found in up to 75%…

When people learn that an artificial intelligence program is evaluating their work or university program, they change their behavior to be more analytical and less emotional. These changes in strategy could lead to inaccurate evaluations and ultimately change who is selected for key positions. The initial findings were recently published in the Proceedings of the National Academy of Sciences. With rapid advances in computing technology, organizations are increasingly using automated tools to screen applicants. Recruiters and university admissions officers are implementing these automated systems to increase efficiency and process large volumes of candidates. These programs often take the form of…

Federal regulators are moving to add microplastics to the list of drinking water contaminants marked for research, funding and future regulation. The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Health and Human Services (HHS) on April 2 announced a series of coordinated actions to protect public health from harms associated with microplastics, which have been found to accumulate in human tissues as they accumulate in the environment. “This is a direct response to the concerns of millions of Americans who have long sought answers about what they and their families are drinking every day,” EPA Administrator Lee…

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…
