Earth’s history is recorded on plates. Over billions of years, their migrations have formed continents, opened oceans, and created climates and environments that allow life to emerge and evolve. But one fundamental question remains unresolved. When did these plates actually start moving? Did Earth’s outer shell start changing as soon as the planet formed 4.5 billion years ago, or did this process begin much later? A new study by Harvard University geoscientists provides the clearest answer yet. Published on March 19th sciencethis study provides the oldest direct evidence of plate movement, dating back 3.5 billion years. The findings show that…

Recent research published in natural neuroscience This suggests that the brain learns to associate certain signals with rewards based on the amount of time that passes between rewards, rather than the number of repetitions. This challenges century-old assumptions about conditioning and provides evidence that the total amount of learning over a period of time is entirely dependent on timing. These discoveries could change our understanding of learning in both animals and humans. For over 100 years, scientists have generally accepted that associative learning works through trial and error. Associative learning is the process by which humans and animals learn to…

A newly identified crocodilian, about 215 million years old, was discovered in Gloucester, England, and was revealed to be a fast-moving land-dwelling predator. This animal resembled the reptilian greyhound and had a slender physique suited for speed. was named Galahadsuchus jonesii In tribute to schoolteacher David Rhys-JonesClose relative of land-dwelling crocodile discovered in Triassic Britain Scientists have identified a new species of early Triassic crocodile relative in Gloucester, England. Unlike modern crocodiles, this animal lived entirely on land and had a body built for speed. With long, slender legs and a lightweight body, they moved quickly through vegetation and likely…

Cancer affects millions of people around the world each year, but treatment remains difficult due to the complexity of the disease. The new findings were published March 17 in an open access journal PLOS Biology Tianyu Jiang and colleagues at Shandong University in Qingdao, China, highlight the possibility of a new strategy. researchers have shown that Escherichia coli Nissle 1917 (EcN) carries anti-cancer compounds and can be modified to target tumors in mice. Bacteria live naturally in the human body and affect both health and disease. Scientists are studying whether these microbes can be redesigned to fight cancer, but their…

New research published in Journal of the Endocrine Society suggest that early-life exposure to per- and polyfluoroalkyl substances (PFAS) may influence bone development in children during adolescence. PFAS are man-made chemicals commonly found in water, food, and a wide range of everyday products. Many of these substances, sometimes referred to as “forever chemicals,” are not easily broken down and can accumulate in the environment and in the human body. Scientists are concerned that this persistence could interfere with normal development, including the formation of healthy bones. “Adolescence is a critical period for building strong bones, and achieving optimal bone mass…

Analysis of Einstein Aging Study data showed that older adults who spend more time awake at night tend to have slower processing speed, worse working memory, and poorer visual memory binding. At an individual level, participants’ processing speed was slower after a night of higher than normal night awakenings. This study Sleep Health: National Sleep Foundation Journal. Sleep is essential for physical health, cognitive function, and emotional regulation. During sleep, your body repairs tissues, strengthens your immune system, and regulates hormones involved in appetite, stress, and growth. Adequate sleep supports memory consolidation and learning by helping the brain process and…

As men age, some cells gradually lose their Y chromosome. For a long time, scientists thought this change had little effect. Because the Y chromosome contains relatively few genes other than those involved in male development, its absence was not expected to affect overall health. That perspective has changed. Research over the past few years has shown that loss of the Y chromosome can lead to serious health problems throughout the body and shorten lifespan. How common are Y chromosome defects? Advances in gene detection have revealed that Y chromosome defects are common in older men. This pattern becomes more…

Happier Japanese adults live longer, a new study published in 2016 found. health psychologyThey found that people who described themselves as unhappy had a significantly higher risk of death over a seven-year period. Happiness has long been linked to improved health, but most of the evidence comes from Western countries. Researchers wonder if the same pattern holds true in cultures where emotional expression is more restrained and definitions of happiness are different. In Japan, for example, happiness is more often associated with calmness and social harmony than with excitement and personal accomplishment. In this context, understanding whether happiness predicts longevity…

The Centers for Medicare and Medicaid Services (CMS) has finalized a rule aimed at phasing out faxed and paper-mailed medical billing documents. The agency’s final rule, released Friday, will establish a national standard for the electronic exchange of clinical documents used to support medical billing. CMS said the rule also adopts standards for electronic signatures to ensure secure and authenticated transmission of this information. This rule is called “Management Simplification.” Adoption of the final rule on standards for health insurance claim attachment transactions and electronic signatures will become effective on May 26. Organizations covered by HIPAA, including health insurance plans,…

Although narcissism is often viewed as a purely harmful personality trait, it actually includes a variety of factors that can protect or harm a person’s mental health. A recent review of hundreds of past studies found that certain volatile forms of narcissism are associated with anxiety and depression, while more confident and sociable forms are associated with higher self-esteem and life satisfaction. This study personality journalhelps clarify how different types of egocentric traits influence psychological health. Rongxia Hou, a psychology researcher at Hunan Normal University in China, led the study. The research team included colleagues from Hunan Normal University, the…
