This research was supported by funding from the National Institute on Aging.physical and mental abilities. But a new study from Yale University paints a much more optimistic picture. This study found that many older adults actually improve over time, and that their beliefs about aging may play an important role in those improvements.Based on more than a decade of data from a large, nationally representative study of older Americans, researchers found that nearly half of adults 65 and older experienced measurable improvements in cognitive function, physical function, or both.The findings suggest that improvement in later life is much more common…

Recent research published in journals dream It has been suggested that certain sleep patterns, such as the time it takes to fall asleep and the amount of interrupted sleep, can predict the likelihood that people with trauma symptoms will experience lucid dreams. These findings provide evidence that the physical characteristics of a person’s sleep cycle are closely related to consciousness during dreaming. This study provides a deeper understanding of how tracking indicators of physical rest can help treat trauma-related nightmares. Lucid dreaming is a unique state of consciousness in which the sleeper is aware that he or she is dreaming…

As the brain develops, newly formed neurons pass through dense tissue to their final destination in the cerebral cortex, where they become part of the brain’s communication network. This movement allows cells to pass through narrow gaps between fibers and adjacent cells. New research published in nature It revealed an unintended consequence of that process. Researchers at the Kyoto University Institute for Cellular and Integrated Sciences (WPI-iCeMS) and collaborating institutions have discovered that migrating neurons routinely experience significant DNA damage. Specifically, cells develop double-strand breaks. This is severe DNA damage that breaks both strands of the DNA double helix. Although…

When you read textbooks, watch wellness influencers, or listen to stories at the gym, it can sometimes feel as if the human body is already mapped to a state of fatigue. Every muscle is named and every nerve is tracked. Everything is understood and readily available. Most people recognize at least a few anatomical terms, such as “trap,” “butt,” and “biceps.” After centuries of dissection, microscopy, and medical imaging, it’s safe to assume that the research is complete. Does anatomy have to be perfect as a discipline? it’s not. Not even close. Ever since Andreas Vesalius published De Humani Corporis…

A comprehensive new study led by UNSW Sydney concludes that nicotine-based e-cigarettes are more likely to cause lung and oral cancer. Published in a magazine carcinogenicThe study assessed a wide range of international studies and brought together experts from multiple institutions including the University of Queensland, Flinders University, the University of Sydney, Royal North Shore Hospital, Prince Charles Hospital and Sunshine Coast University Hospital. The research team included experts from multiple fields, including pharmacy, epidemiology, thoracic surgery, and public health. They sought to determine whether e-cigarettes themselves could contribute to the development of cancer by examining evidence from various scientific…

Certain cognitive skills, such as reading comprehension, math skills, and processing speed, are strongly influenced by genetics, even though they are separate from a person’s overall intelligence. A large-scale new meta-analysis reveals that specific cognitive abilities, like general intelligence, depend on inherited DNA. This distinction opens the door to future genetic profiles that will help guide personalized education. The study was published in the journal Intelligence. Historically, psychology and behavioral genetics have focused on general cognitive abilities, often referred to as general intelligence. This concept sits at the top of a widely used psychological framework called the Cattell-Horn-Carroll model of…

When people debate highly controversial issues, they often misrepresent the other side’s arguments. A recent study tested whether individuals can accurately describe the beliefs of their political or social opponents and found that people are generally very good at understanding opinions with which they disagree. These results are cognitive science. Measuring open-mindedness has historically been a challenge for psychologists. Traditionally, researchers have used self-report surveys that ask people to rate their intellectual habits. Participants may be asked to agree or disagree with statements about whether or not to listen to contradictory evidence. Other surveys ask people to say whether they…

Researchers at the University of Arizona Health Sciences identified the following compounds: cannabis sativa A plant that could offer a new way to treat fibromyalgia and post-surgical pain. The survey results are pharmacological reportthere is growing evidence that certain cannabis-derived molecules may help relieve chronic pain without causing the psychoactive effects associated with THC. This study builds on previous work in the lab of Dr. John Streicher, a member of the Comprehensive Center for Pain and Addiction, which found that terpenes can reduce pain in models of inflammation and chemotherapy-related nerve injury. “Our research shows that terpenes are not a…

Researchers at the University of Technology Sydney have demonstrated a new way to control tiny quantum light sources by twisting atomically thin layers of hexagonal boron nitride. This advance provides scientists with a new way to tune quantum emitters. Quantum emitters are tiny light sources that could play a key role in future technologies such as quantum computing, secure communications, and ultra-sensitive sensors. Lead author Dr Angus Gale said the study provides researchers with a valuable new tool to make these quantum systems more practical. “We can measure these quantum emitters and confirm their existence, but it’s difficult to actually…

A night without sleep leaves certain chemical traces in saliva that can be reliably detected with high accuracy. A recent study published in the Journal of Proteome Research provides evidence that acute sleep deprivation creates a unique pattern of molecules in the mouth, ultimately paving the way for rapid tests that can identify exhausted drivers and workers. This study suggests that as few as 10 to 12 specific biomarkers are sufficient to distinguish between those who are awake 24 hours a day and those who are well rested. A team of scientists from the University of Zurich in Switzerland designed…
