Recalling memories of a deceased loved one can cause a measurable physical increase in blood pressure, and for people suffering from long-term grief, this physical stress response may not subside normally. A recent study found that thinking about the deceased triggers cardiovascular changes similar to acute stress for up to two years after the loss. The study was published in the journal Biopsychosocial Sciences and Medicine. Losing a close friend or family member is one of the most powerful stressors a human can experience. Psychologists and medical professionals recognize that grief is much more than emotional distress. In fact, bereavement…

A widely used sodium-ion battery developed by Chinese manufacturer Hina has achieved performance and manufacturing quality levels comparable to Tesla’s lithium-ion batteries, according to a study published in the journal Cell Press. cell report physical science. The findings suggest that sodium ion technology could provide a low-cost alternative for future electric vehicles and large-scale energy storage systems. However, achieving that goal will require further improvements in battery cold charging and energy density. Unlike lithium, sodium is abundant and readily available, making it an attractive material for reducing battery costs and supply chain concerns. “The combination of good uniformity, high power…

Age progresses differently depending on the person. Some people don’t get seriously ill as they get older, but others develop serious health problems much earlier. As populations around the world continue to age, understanding why this happens becomes increasingly important. Although life expectancy has increased dramatically over the past 200 years, the number of years people spend in good health has not increased at the same pace. Researchers have long known that abnormal longevity (longevity) often runs in families and is associated with later onset of chronic diseases. However, the genetic factors that help protect these families are still poorly…

A daily diary study that looked at the relationship between different symptoms of depression found that higher levels of sleep disturbance, sad mood, and difficulty concentrating were associated with higher levels of several different symptoms the next day. Those with higher levels of anhedonia, anxiety, and difficulty concentrating tended to experience a broader range of depressive symptoms. The paper was published in. British Journal of Psychology. Depression is a mental health condition characterized by persistent low mood or loss of interest or enjoyment, which interferes with daily life. It’s different from normal sadness. This is because the symptoms usually last…

A study by researchers at St. Mary’s University found that microplastics can shorten the lifespans of microscopic insects, inhibit their reproduction, and act as toxic carriers that carry chemicals and plastic additives into the body once ingested. Jennifer Herr is a biology professor and researcher specializing in biochemistry, epigenetics, and forensics, and has been at Saint Mary’s University since 2019. Ha led the study and a team of undergraduate researchers. Their findings were published in December. micro plasticis an open access, peer-reviewed journal focused on the science behind microplastics. Microplastics are small pieces of plastic that have become an increasingly…

New research suggests that when people are distracted by a visual task, they’re more likely to consciously notice neutral spoken words than negative ones. These findings published in the journal psychological scienceprovides evidence that the human brain may filter out distracting emotional sounds before they reach consciousness. This research helps explain how the mind manages the overwhelming amount of auditory information we encounter every day. Our sensory environment is filled with a constant stream of sights and sounds. Because humans have limited attention spans, our brains must prioritize which information enters our consciousness. Conscious awareness refers to our ability to…

Scientists at Baylor College of Medicine have identified a potential new approach to tackling Alzheimer’s and Parkinson’s diseases. Both conditions are associated with the accumulation of harmful clumps formed by the proteins tau and alpha-synuclein in the brain. In a study published in nature communicationsResearchers have discovered that tubulin, a protein that functions as a component of microtubules, may help prevent the buildup of these toxic substances. Microtubules act as “railroads” inside cells, helping to transport materials and maintain structure. The findings show that tubulin can prevent tau and alpha-synuclein from forming damaging aggregates and instead encourage them to perform…

The more certain an AI lie detection system is to accuse someone of deception, the more likely people will distrust it, and this distrust will actively undermine the AI’s accuracy. This new research Computers in human behavior. Artificial intelligence (AI) has proven to have an uncanny ability to spot deception. By analyzing patterns in written language, AI models can classify statements as truthful or deceptive with an accuracy far beyond what humans can typically achieve on their own. In fact, research has shown that trained professionals, such as civilians and police officers, perform only slightly better than chance when trying…

The lakes, rivers, and ponds you’ve been visiting for years are probably looking browner than they used to. And people fishing in these waters may be catching different types and sizes of fish than before. Our study identified a link between these two developments. This means that trout, bass, perch, and whitefish may be less common in lakes without fish. But pike and walleye anglers may be in for a trophy-sized surprise. Over the past few decades, many freshwater ecosystems in much of northeastern North America and northern Europe are darkening and, as a result, changing in other ways.What is…

aDougna Woessa was a young boy when drought first tore his country apart. When crops failed in Ethiopia’s rain-starved regions in the early 1970s, and his school turned classrooms into granaries for farmers to send aid, he never imagined that scientists would begin to link the forces that depleted fields to the cyclical changes in trade winds that have long accelerated violent weather from South America to Australia.Now infamous El Niño – means “little boy” in Spanish – Although it was named by Pacific fishermen in the 1800s, it wasn’t until the 1970s that scientists began to understand its global…
