As the world grapples with climate change and dwindling fossil fuel reserves, biodiesel emerges as a promising renewable alternative to conventional diesel. However, the journey toward sustainable biodiesel production faces significant hurdles, particularly in selecting the right feedstocks that don't compete with food supplies. A groundbreaking comprehensive review reveals how artificial neural networks (ANNs) and deep learning technologies are revolutionizing this field, offering unprecedented solutions to longstanding challenges.

As our cities choke on exhaust fumes and climate change accelerates, electric vehicles (EVs) have emerged as our beacon of hope. Yet, despite their promise, EVs face a critical challenge that limits their widespread adoption: the delicate balance between driving efficiency and ride comfort. Every time you press the accelerator in an electric car, the motor must deliver power efficiently while minimizing vibrations that can make your journey uncomfortable and reduce the vehicle's lifespan.

New research warns of declining access to safe, reliable and affordable water in the U.S., urging for better water tracking tools and immediate policy reforms.

New Arizona State University research reveals the extent to which sewage pollution threatens the fragile coral reef ecosystems of West Hawaiʻi Island. The study identifies exactly where sewage-contaminated water is entering the ocean, further damaging coral reefs already impacted by climate change, and endangering human health. The research team used advanced airborne mapping techniques, along with comprehensive field sampling and sophisticated statistical models, to pinpoint locations where high levels of fecal bacteria associated with populated coastal areas are driving worsening contamination. The study provides the critical data needed by government officials and local communities to mitigate this threat and protect the health and biodiversity of coastal ecosystems.

Cities are particularly vulnerable to heat stress because paved and densely built-up areas tend to store the heat. More frequent and intense heatwaves are a growing challenge for public health and urban infrastructure. A new deep-learning based model developed by the University of Freiburg and Karlsruhe Institute of Technology (KIT) calculates for the first time how heat stress will develop on each square meter of a city in the future. The model supports cities in their efforts to adapt to the climate change and provides stimuli for climate-friendly urban planning. Published in Urban Climate.  (DOI: 10.1016/j.uclim.2025.102564)

A previously untapped source of data sheds new light on the climate of the early Earth: fossilized dinosaur teeth show that the atmosphere during the Mesozoic era, between 252 and 66 million years ago, contained far more carbon dioxide than it does today. An international research team at the Universities of Göttingen, Mainz and Bochum made this discovery by analysing oxygen isotopes in tooth enamel. They used a newly developed method that opens up opportunities for research into the Earth's climate history. In addition, the researchers found that total photosynthesis from plants around the world was twice as high as it is today. This probably contributed to the dynamic climate during the time of the dinosaurs. The results were published in the journal PNAS.

Drivers can now compare the greenhouse gas emissions of different vehicles based on size, usage, powertrain type and even location
