A recent study conducted by Vanderbilt University Medical Center (VUMC) reveals the promising potential of artificial intelligence (AI) in improving suicide prevention efforts in medical settings. Led by Dr. Colin Walsh, MD, MA, an associate professor of Biomedical Informatics, Medicine, and Psychiatry, the team developed a novel AI system called the Vanderbilt Suicide Attempt and … Read more
For nearly two centuries, the identity of the volcano responsible for a massive eruption in 1831 remained an enduring mystery, captivating scientists and historians alike. The event, marked by dramatic global cooling, failed crops, and famine, was known only as Earth’s most recent “mystery eruption.” Now, researchers from the University of St Andrews have finally … Read more
The preservation of ecosystems and biodiversity is a pressing global issue, with many regions around the world seeking innovative strategies to combat habitat loss, species extinction, and environmental degradation. In Sub-Saharan Africa, which harbors 13% of the world’s biodiversity and approximately 20% of the planet’s forests, the stakes are particularly high. Recognizing the vital importance … Read more
The image taken by the NASA/ESA Hubble Space Telescope for the Week of January 3, 2025, offers a stunning view of the galaxy LEDA 22057, situated a remarkable 650 million light-years away in the constellation Gemini. This particular galaxy has been the site of another dramatic astronomical event—a supernova explosion, labeled SN 2024PI, that was … Read more
An international team of paleobiologists, anthropologists, and behavioral scientists has recently made an intriguing discovery that bridges the gap between ancient human behavior and modern chimpanzee tool-use practices. Published in The Journal of Human Evolution, the team’s research highlights how the methods used by chimpanzees to select stones for nut-cracking might resemble the process once … Read more
Parkinson’s disease is a progressive neurodegenerative disorder that primarily affects a person’s movement. It occurs when the brain’s production of dopamine—a crucial neurotransmitter that helps regulate movement—begins to decline. This loss of dopamine disrupts communication between the brain and the muscles, leading to symptoms such as tremors, stiffness, and slowness of movement. As Parkinson’s disease … Read more
A study led by researchers at the American Museum of Natural History provides an unprecedented glimpse into one of the earliest recorded evolutionary arms races between predator and prey. This arms race occurred over 500 million years ago during the Cambrian Period, specifically in what is now South Australia. The study, published in the journal … Read more
Since its discovery in the early 1990s, programmed cell death protein 1 (PD-1) has become a pivotal target in cancer research. A checkpoint receptor found on immune system cells, particularly T cells, PD-1 plays a crucial role in maintaining immune tolerance. Under normal circumstances, PD-1 functions as a sort of “off switch” to regulate immune … Read more
Life as we know it would not exist without carbon, one of the essential building blocks of all known life forms. From the oxygen in our atmosphere to the iron in the core of Earth, and even the very bodies of life forms—from humans to bacteria—these elements owe their existence to stars. Carbon, along with … Read more
A team of chemical engineers from Deakin University, in collaboration with researchers from the University of Western Australia, the University of Sydney, and Monash University, has uncovered a promising method that may change the way we cool our homes. Their groundbreaking work, published in the renowned journal Science, explores a novel refrigeration technology that could … Read more
