A rare type of meteorite known as a CO chondrite may be the object that crashed into Earth 66 million years ago and caused the extinction of about 75 percent of all species, including all non-avian dinosaurs. Researchers from the University of British Columbia (UBC), Paris, Brussels, and Vienna reached that conclusion by analyzing nickel isotopes preserved in material left behind by the Cretaceous-Paleogene collision. Their discovery is scientific progress. The rare meteorite behind the extinction of dinosaurs “Ornans-class carbonaceous chondrites are clearly different from the typical meteors found in museum collections,” says Dr. Philip Claeys, who worked on the…
A widely available antidepressant drug may provide meaningful relief for people experiencing persistent fatigue from long-term COVID-19 infections, according to a global clinical trial co-led by McMaster University. Researchers have found that fluvoxamine (sold under the brand name Luvox), an inexpensive drug already commonly used to treat depression and other symptoms, reduces fatigue and improves quality of life in adults with long-term COVID-19 infections. This randomized, placebo-controlled trial Annual report of internal medicine. Possible treatment for long-term coronavirus fatigue Fatigue is one of the most frequent and disabling symptoms reported by people with long-term COVID-19 infection. For some people, fatigue…
Microplastic pollution has become a global cleanup problem with no clear end point. Filtration can capture some particles, dredging removes contaminated sediment, and chemical treatments can change certain polymers, but these interventions are expensive, incomplete, and often move plastic from one place to another rather than destroying it. A new scientific review claims the most promising alternative may come from organisms too small to see. “Microbial bioremediation of microplastic pollution for sustainable ecosystems and a greener future: A review” Published in applied microbiologyinvestigates how bacteria, fungi, microbial communities, and plastic-degrading enzymes can potentially break down synthetic polymers and convert their…
A new analysis of brain imaging data reveals that lysergic acid diethylamide, commonly known as LSD, reduces the synchronization of local brain activity, producing mind-altering effects. The study, published in the European Journal of Neuroscience, suggests that psychedelics interact with a wider range of brain receptors than previously thought. These insights may help map the biological mechanisms underlying altered states of consciousness and inform future therapeutic uses of psychedelics. Over the past decade, medical researchers have renewed their focus on classic psychedelic drugs as potential treatments for mental illness. Compounds such as LSD and psilocybin cause significant changes in perception,…
overview: For decades, highways and industrial roads have exposed Black communities to disproportionate levels of diesel pollution. As the Trump administration eases clean-truck standards, environmentalists warn these regions could once again pay the highest price. The study is conclusive: Black communities are disproportionately exposed to diesel exhaust and other traffic-related pollution. So when the Biden administration-era crackdown on diesel emissions was scheduled to go into effect, Black neighborhoods near highways and industrial areas expected to breathe easier. But the Environmental Protection Agency’s new move means the air quality in those communities could get worse, and could get worse soon. Read…
When people read poetry strictly for its beauty, their brains go through a distinct three-step process that separates emotional resonance from basic reading comprehension. Researchers mapped brain activity and found that readers temporarily quiet their brain’s language-processing centers in order to fully immerse themselves in the images and emotions of the text. The results of this study were published in the journal NeuroImage. In the fields of education and literature, scholars often divide reading into two distinct categories. The first is efferent reading. This happens when we read to extract facts, analyze writing techniques, or gather objective information. The second…
Recent research published in JMIR mHealth and uHealth A wearable device that sends gentle vibrations to the body could help people sleep longer, a study suggests. The study results provide evidence that this non-invasive technology tends to significantly increase total sleep time, especially for people who have difficulty getting enough rest throughout the night. This approach offers a promising non-drug option for addressing chronic sleep deprivation and improving overall health. A significant portion of the world’s population does not get enough sleep each night. Approximately 70 million adults in the United States regularly sleep 6 hours or less. Medical experts…
When a massive subduction zone off the coast of the Pacific Northwest eventually moves, the consequences could be catastrophic. When an earthquake with a magnitude of 9 or higher occurs, the ground shakes violently, causing tsunamis and landslides, which spread the destruction. Now, a study has been published earth sphere It suggests that this long-feared “really big thing” may not be acting alone. It could also trigger powerful earthquakes along the San Andreas Fault in California. “It’s hard to overstate what a magnitude 9 earthquake would be like in the Pacific Northwest,” said Dr. Chris Goldfinger, a paleoseismologist at Oregon…
About 800 million years ago, a violent collision in the asteroid belt may have triggered a long wave of collisions in the inner solar system, according to research led by the Southwest Research Institute. Researchers propose that the breakup of the parent body that formed the Eulalia asteroid family sent large amounts of debris flying toward Earth, the Moon, and Mars. If this relationship is correct, this event may have caused geological changes on several worlds and even influenced Earth’s climate and biosphere. Ancient influences and history of life “The role that impacts played in shaping the origin and evolution…
A meta-analysis of data from three large panel studies found that extraversion, conscientiousness, and emotional stability at a given point in time predicted slightly lower levels of loneliness four years later compared to an individual’s typical levels of these traits. However, higher levels of loneliness also predicted lower levels of these same three traits four years later. The paper was published in. personality journal. Loneliness is the painful feeling that social relationships are fewer, less intimate, or less satisfying than desired. Because this is a subjective experience, it differs from social isolation, which objectively refers to having little social contact.…
