Scientists have observed time dilation in the variability of quasars, an effect predicted by Einstein’s theory of relativity. Continue reading Einstein was right: testing the theory of relativity using quasars
ChatGPT is transforming work, learning, and writing. A new AI tool can accurately distinguish human academic writing from ChatGPT with 99% accuracy. Continue reading New Tool Developed to Spot Artificial Intelligence in Academic Writing
In a recent study from UCSF and MIT, researchers found that they could identify evolutionary differences in biological function by comparing the results of CRISPR screens in humans and chimpanzees. Continue reading Scientists compare CRISPR screens in chimpanzee and human cells to understand evolution
by Nicolai Penafigures by Jasmin Joseph-Chazan Toward the end of the 20th century, the intricate biology of how the eye produces visual information was thought to be well understood– a combination of sensors and circuits in the eye extract features of visual scenes. This information is conveyed from the eye to the brain by specialized neurons that physically connect the two structures (Figure 1, blue). … Continue reading Vision you can’t see: How the brain senses the time of day
by Hannah Blumefigures by Salvador Balkus In some ways, a living cell is like a shoreline, where some creatures build their homes on rocky, solid structures while others live in shifting and dynamic sands. This ecosystem needs both rigid and fluid structures to support life, and similarly, individual cells in our bodies use both structured and fluid compartments to carry out vital functions. The existence … Continue reading Liquid-within-liquid compartments: a groundbreaking discovery in biology
Are you talking to a human or a chatbot? Ask them this question to find out. Continue reading Unmasking AI with a Single Question
by Shreya Johrifigures by Cynthia Moncada-Reid What if AI could design personalized workout plans, craft tailored travel itineraries, or even compose cover letters for job applications? With the advent of ChatGPT, it can. ChatGPT is an AI-powered chatbot that uses a cutting-edge machine learning architecture called GPT (Generative Pre-trained Transformer) to generate responses that closely resemble those of a human. Developed by OpenAI, ChatGPT is … Continue reading The Making of ChatGPT: From Data to Dialogue
Rivers, skies, and mountains become legal persons under Rights of Nature laws, but their implementation has been difficult. To help interpret and enforce these laws, scientific knowledge must be integrated. Continue reading Can Science Boost the Rights of Nature Movement?
New research from Northwestern University found that, when predicting heart disease, including genetic information had a minimal improvement compared to a more common test. Continue reading Genetic risk prediction for heart disease underperforms in large research cohort
by Gizem Terzioglufigures by MJ Park Alzheimer’s disease is a progressive neurodegenerative disorder that affects millions of people worldwide, and despite years of research efforts, there is still no cure. However, recent studies have highlighted the crucial roles of microglia, the resident immune cells of our brain, in the development and progression of Alzheimer’s disease. But the question remains: do microglia defend our brain against … Continue reading Are microglia the hero or the villain in Alzheimer’s disease?
