A large survey of American adults shows that while the majority supports democratic values, millions of individuals hold views sympathetic to authoritarianism and the government’s use of domestic force. While the individual willingness to engage in political violence remains low among the population, these alternative political preferences are creating a social climate that may encourage democratic backsliding. The study results were published in the journal Injury Epidemiology. Over the past decade, social scientists and policy experts have expressed growing concerns about the health of American democracy. Recent events have been marked by intense political polarization, civil unrest, and changes in…

Recent research published in molecular psychiatry There is evidence that experiencing abuse at various stages in childhood and adolescence changes how the brain processes emotions in adulthood. This study suggests that the particular age at which trauma occurs tends to determine which emotional processing areas of the brain become overactive later in life. These findings provide insight into why childhood maltreatment increases the risk of mental health disorders such as depression and post-traumatic stress disorder (PTSD). The brain relies on a network of highly interconnected structures to interpret and respond to the social world. The two main regions involved in…

An evidence-based analysis of scientific gaps in the 2025-2030 dietary guidelines, focusing on protein, fats, ultraprocessed foods, and integrations with GLP-1 therapies for improved metabolic outcomes.

To commemorate the United States’ 250th anniversary, NASA has released four spectacular images of deep space from the Chandra X-ray Observatory. Each image is rendered in patriotic shades of red, white, and blue. In addition to images, the station also announced three new sonifications that convert stargazing into sound, offering another way to experience the universe.This collection combines data from Chandra with observations from other telescopes to showcase some of the universe’s most remarkable objects, from the remains of exploding stars to distant galaxy clusters filled with evidence of dark matter.Cassiopeia A reveals the aftermath of a stellar explosionThe first…

College students facing heavy workloads are increasingly turning to artificial intelligence tools to manage stress, but new research suggests this habit may backfire. Researchers have found that relying on artificial intelligence to handle mental tasks leads to decreased confidence in one’s abilities, which is associated with increased academic burnout and anxiety. These findings were published in BMC Psychology. It is very common for learners to look for external resources when they feel overwhelmed with schoolwork. The practice of transferring information or mental processes to external tools to reduce mental effort is called cognitive offloading. Cognitive offloading occurs in educational settings…

In the complex world of honey bee colonies, the queen plays a critical role not only as the hive mother but also as a central figure in survival from environmental challenges such as exposure to pesticides. Recent groundbreaking research has revealed that queen bees employ unique biological mechanisms to cope with chronic pesticide pollution. This is a process known as maternal offloading, where the queen transfers toxic chemicals directly to the eggs. The findings, published in the prestigious journal Current Biology, represent a major advance in our understanding of how pesticides penetrate and persist within the colony’s ecosystem, ultimately impacting…

Physicists have developed a new way to control the rotation of molecules within tiny droplets of liquid helium, marking a significant advance in the study of superfluids. Using a specially designed optical centrifuge, the team was able to precisely rotate the molecules suspended in nanodroplets of liquid helium, giving scientists a powerful new tool to explore these unusual frictionless materials. This result marks the first successful demonstration of controlled molecular rotation in a superfluid. Researchers can now directly tune both the direction and speed of a molecule’s rotation, allowing them to investigate how molecules interact with their quantum environment at…

A new study published in the Journal of Social and Personal Relationships and Personal Relationships suggests that people who mislead their romantic partners tend to fall into three specific behavioral categories. By investigating the psychological reasons behind romantic deception, scientists have shown evidence that lies in intimate relationships serve a variety of purposes. These objectives range from attempts to maintain relationship harmony to calculated strategies to manipulate emotions. Tim Cole is an associate professor in the Department of Communication at DePaul University and author of “ Broken Trust: Overcoming Intimate Betrayalconducted the study with Kelly Stonebrook. “This is one of…

If you look at it, Names such as “potassium sorbate,” “citric acid,” and “L-ascorbic acid (vitamin C)” are often seen on the ingredient labels of foods on supermarket shelves. These are food additives intended to prevent spoilage and maintain quality, and are widely included in industrially produced processed foods. According to Open Food Facts, the world’s largest open food database, more than 20% of processed foods and beverages in the database contain at least one preservative.Against this backdrop, a research team led by scientists from Sorbonne Paris North University and Paris Cité University analyzed data from the large NutriNet Santé…

Researchers at the Johns Hopkins School of Medicine and the Johns Hopkins Bloomberg School of Public Health have developed an experimental DNA vaccine to treat tuberculosis (TB) that is administered through the nose. The vaccine is designed to help the immune system identify and attack drug-resistant tuberculosis bacteria known as “persisters,” which can withstand long-term antibiotic treatment and later cause a relapse of the disease. The survey results are clinical research journal. Tuberculosis has plagued humanity for at least 6,000 years and remains one of the world’s deadliest infectious diseases. According to the World Health Organization (WHO), about a quarter…
