Scientists Use Computer Models to Determine Cause of Dinosaur Extinction

Scientists have long debated whether the extinction of dinosaurs was caused by massive volcanic eruptions or the impact of a giant asteroid. To settle the issue, a group of researchers from Dartmouth developed a computer model that analyzed geological and climate data to determine the most likely cause of the Cretaceous-Paleogene extinction event. Using Bayesian inversion modeling and machine learning, the unbiased model concluded that gases emitted from the Deccan Traps shield volcano over a period of 300,000 years triggered the extinction.

Children with Autism and ADHD Struggle to Clear BPA from Their Systems

A recent study found that children with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) have a reduced ability to clear the chemical compound bisphenol A (BPA) from their systems. BPA is commonly found in plastic water bottles, polycarbonates, epoxy resins, thermal paper, and PVC manufacturing. Researchers suggest that the rise in diagnoses of ASD and ADHD over the years may be influenced by various factors, including exposure to BPA.

Researchers Develop Technique to Treat PFAS Toxins in Contaminated Groundwater

Scientists at The Ohio State University have discovered a new technique that shows promise in treating per- and polyfluoroalkyl substances (PFAS) toxins in contaminated groundwater. PFAS compounds, commonly found in nonstick cookware, industrial foams, and stain-resistant carpet, have been linked to various health issues. The researchers used ultrasound degradation to weaken the chemical bonds of fluortelomer sulfonates, a type of PFAS compound. This technique may also be effective in degrading pharmaceuticals in municipal tap and wastewater.

NASA Captures Time-Lapse Footage of Supernova Remnants

NASA released stunning time-lapse footage of stellar remnants from a supernova explosion that occurred 20,000 years ago. Using the Hubble Space Telescope, astronomers observed a small area of the Cygnus Loop nebula, showing the ongoing expansion of the supernova bubble. The footage reveals that the remnants of the star are hurtling into space at a speed of half a million miles per hour.

Study Highlights the Consequences of Dishonesty in Society

Researchers have discovered a phenomenon called “honesty drain,” in which honest individuals tend to leave areas where cheating is prevalent. This migration of honest people leads to a decline in the quality of the political class, reduced earning growth, and decreased labor productivity. In Italy, false birth registrations are used as an indicator of regional honesty. Citizens who migrate from high-cheating areas to low-cheating areas are less likely to have false birth certificates.
