Dr. Rowan Martindale, a paleoecologist and geobiologist at the University of Texas at Austin, was hiking through the Dades Valley in Morocco’s Central High Atlas Mountains when something unusual caught his attention. A research team including Martindale and Aarhus University’s Stefan Bodin were exploring the rugged valley to study the ecology of the ancient coral reef system that existed there when the area was once under the sea. Reaching these reefs required crossing several layers of turbidites, deposits formed by dense underwater debris flows. These deposits often exhibit ripple patterns. However, Martindale noticed that the small bumps and wrinkles superimposed…

An eight-month study of college students found that students who received autonomy support from others tended to have slightly better subjective well-being. They also showed small increases in agreeableness, conscientiousness, and openness to experience. The paper was published in. personality journal. Autonomous support from others refers to interpersonal behaviors that foster an individual’s sense of initiative and psychological freedom, rather than controlling or pressuring them. This is a central concept in a macro-theoretical framework in psychology called self-determination theory. Supporting autonomy involves acknowledging the perspective of others, even if you disagree with it. This includes providing meaningful options rather than…

The amount of fiber you consume has a huge impact on your overall health. Fiber supports healthy digestion and has been linked to a lower risk of certain cancers, among many other benefits. This increased awareness may help explain why the “fibermax” trend is gaining traction. Fibermaxxing refers to consuming at least the recommended daily amount of fiber for your body weight each day. This idea has gained traction across social and traditional media this year. Jennifer Lee is a scientist at the Gene Mayer USDA Human Nutrition Research Center on Aging at Tufts University. Her research focuses on how…

New research published in Frontiers of human neuroscience suggest that assistive robots may work best when they share control with the user and are at a halfway point between full automation and manual operation. People with severe movement disorders, such as amyotrophic lateral sclerosis (ALS), often require constant assistance from a caregiver with daily tasks such as cooking, eating, and moving objects. Bodily assistive robots have the potential to restore independence, but many existing systems are limited to simple pre-programmed tasks. Brain-robot interfaces, which allow users to control robots using brain signals, offer a promising alternative, but are often noisy,…

Recent public health studies have found a clear link between exposure to common air pollutants and the occurrence of suicidal ideation in adults. This study suggests that chemicals found in everyday products and car exhaust can have a negative impact on human mental health. These results are Affective Disorders Journal. Suicide remains a major public health challenge worldwide. Hundreds of thousands of people die by suicide every year. Suicide rates have continued to rise in the United States over the past decade. Suicidal ideation is a term used to describe thoughts of self-harm or planning one’s own death. Experiencing such…

Microplastics are usually discussed as an ocean problem. But they also accumulate in agricultural soils, and a new scientific review claims their effects go beyond physical contamination. A research team led by Jiangsu University focuses on what happens at the microscopic level on the surface of plastic particles, where microorganisms meet, compete and exchange genes. These interactions can affect soil fertility, ecosystem recovery and the long-term sustainability of agriculture, they say.Microplastics are pieces of plastic smaller than 5 millimeters. In agricultural environments, they can arrive through the decomposition of plastic mulch, sewage sludge, irrigation water, and larger plastic…

New research published in Personality and Social Psychology Bulletin provides evidence that holding grudges is caused by a specific emotional cocktail that mixes both hurt feelings and anger. This finding suggests that when these two emotions are combined, victims tend to view the person who wronged them as fundamentally immoral, which fosters lasting resentment. This psychological change acts as a type of self-defense, helping people protect themselves from future harm by maintaining vigilance against those who have betrayed them. Building close social bonds is a basic need for human survival, but relationships are inevitably threatened when one party causes harm…

Psilocybin, the psychoactive compound found in magic mushrooms, is of interest to scientists studying treatments for depression, anxiety, substance use disorders, and some neurodegenerative diseases. Despite its potential therapeutic effects, the strong hallucinogenic effects associated with this compound may limit its scope of use in medicine. In the study published in the ACS Journal of Medicinal Chemistry, scientists created a modified form of psilocin, the active compound produced when psilocybin is processed in the body. In early studies in mice, these new molecules caused less hallucinogen-like effects than pharmaceutical-grade psilocybin, while retaining biological activity. “Our findings are consistent with a…

Recent research suggests that eating ultra-processed foods does not accelerate cognitive decline in older adults over a 10-year period. This study european nutrition journalprovides evidence that overall diet quality may be more important than specific levels of food processing in maintaining brain health as we age. These findings help uncover the complex relationship between what people eat and how their brains change over time. As the world’s population ages, the number of people living with dementia is expected to increase dramatically in the coming decades. There is currently no cure for dementia, so it is critical to identify lifestyle factors…

Accumulation of tau protein in the brain is a defining feature of Alzheimer’s disease. According to a study published March 5 in the journal Cell Press. Cell Press Blueresearchers describe a newly identified biological process that may help explain how tau accumulates. The study combined animal experiments, cell studies, and patient tissue analysis. The findings point to the important role of tannycytes, specialized brain cells that help regulate communication between the brain and the rest of the body. “Our findings reveal a previously underestimated, disease-relevant role for tanycytes in neurodegeneration,” said corresponding author Vincent Prevot from INSERM in France. “Focusing…
