A new study suggests that a single dose of the psychedelic compound DMT can reverse symptoms of depression, such as anhedonia and decline in cognitive function, in mice exposed to chronic stress. The findings provide evidence that the drug helps repair brain circuits by promoting the healthy growth and integration of new neurons. The study was published in the journal translational psychiatry. Major depressive disorder is a leading cause of disability worldwide. Traditional antidepressants, such as selective serotonin reuptake inhibitors, often take several weeks to become effective and fail to help a significant proportion of patients. This delay and lack…

About 15% of asteroids that pass close to Earth have a smaller companion star orbiting them. These paired objects are known as binary asteroid systems and are surprisingly common in our region of the solar system. A research team led by the University of Maryland has discovered that these systems are much more active than scientists once thought. Rather than simply orbiting each other, the two bodies exchange rocks and dust through gentle, slow impacts that gradually reshape their surfaces over millions of years. The discovery comes from a close analysis of images taken just before NASA’s Double Asteroid Redirect…

Stepping outside or putting mint in your mouth on a cold winter morning will instantly give you a cooling sensation. The sensation begins with tiny sensors in your body that signal your brain when something is cold. Scientists have created the first detailed images of how this sensor works, revealing how it responds to both actual temperature drops and menthol, a cooling compound found in mint plants. The findings were presented at the 70th Annual Meeting of the Biophysical Society in San Francisco. The study focused on a protein channel known as TRPM8. “Imagine TRPM8 as a microscopic thermometer inside…

Around 643,000 tonnes of sewage sludge is being sprayed on fields in Scotland amid mounting evidence that it contains a mixture of toxic chemicals, The Ferret has revealed.Data obtained from the Scottish Environment Protection Agency (CEPA) through Freedom of Information details the extent to which the substance was applied in rural areas across the country between 2020 and 2024.Sewage sludge is a by-product of domestic and industrial sewage and wastewater and is treated by Scottish Water and Waste and Water Management companies, during which some pollutants are removed.The slurry residue is then fed or sold to farmers as a low-cost,…

A new study from Northwestern University warns that organized scientific fraud is becoming increasingly common. Researchers say organized groups manipulate the academic publishing system, from fabricated data to author purchases and paid citations. To investigate this issue, scientists combined extensive analysis of scientific publications with detailed case studies. Although fraud is often portrayed as the result of omissions on the part of individual researchers, a team of researchers at Northwestern University discovered something much more complex. Their findings revealed a global network of people and organizations working together to systematically exploit weaknesses in the publishing process. The scale of the…

People who reported using their smartphones while sitting on the toilet were more likely to get hemorrhoids than those who did not use their smartphones while on the toilet. The findings come from a new study led by Chesan Ramprasad of Beth Israel Deaconess Medical Center in the US and published in an open access journal. pro swan. Millions of people suffer from hemorrhoids every year Hemorrhoids are very common in the United States. Each year, nearly 4 million patients visit doctors and emergency rooms, resulting in more than $800 million in healthcare costs. In this disease, the veins in…

New archaeological research suggests that seabird guano, the nutrient-rich bird droppings, may have played a major role in transforming ancient Peruvian agriculture and helped the Chincha kingdom emerge as one of the most prosperous and influential societies before the Incas. The study’s lead author, Dr Jacob Bongarth, a digital archaeologist at the University of Sydney and a visiting fellow at the Australian Museum Institute, said the findings reveal the surprisingly powerful influence bird droppings had on Andean civilization. “Although seabird guano may seem trivial, our study suggests that this powerful resource may have contributed significantly to sociopolitical and economic changes…

The brain relies on countless chemical messages to keep its networks running smoothly. You can imagine this system similar to traffic lights guiding cars through a busy city. The new study focused on nitric oxide, a common chemical messenger in the brain. Researchers have found that in some cases of autism, elevated levels of this molecule may no longer act as a beneficial signal, but instead act more like a “button turned off” state. When nitric oxide triggers this chain of events, an important protective protein called TSC2 begins to disappear. TSC2 normally helps regulate a major cellular control system…

All-solid-state batteries (ASSBs) are widely recognized as a potentially safer and more energy-dense alternative to traditional lithium-ion batteries. Its performance depends largely on how fast ions can move through the solid electrolyte. Identifying materials that enable this rapid ion transfer has traditionally required time-consuming synthesis and experimental characterization. Researchers also rely on computer simulations, but existing computational approaches often struggle to accurately model the complex and chaotic behavior of ions at high temperatures. Another major challenge is detecting and predicting when ions move through a crystal like a liquid. Standard computational techniques that attempt to calculate the properties of such…

Many people believe that the world will soon come to an end, and these apocalyptic views shape how we respond to real global threats such as climate change and artificial intelligence. New research published in Journal of Personality and Social Psychology These stories reveal that individuals are deciding whether they want to prevent or ignore impending global crises. By mapping the specific characteristics of these apocalyptic beliefs, researchers can predict public responses to the major dangers of our time. People from different backgrounds have ideas about Revelation. Some expect religious prophecies to unfold, while others predict environmental collapse. To understand…
