Beef production releases more than twice the target of greenhouse gases, a Brazilian study found
Credit: Pixabay/CC0 Public Domain One of the pillars of the Brazilian economy and one of the sectors with the highest greenhouse gas emissions in Brazil currently practiced, one of the sectors that emit more than twice the limits needed to achieve international environmental targets. This is one of the conclusions of the research published in the journal Environmental Science and…

AI systems target tree pollen behind allergies
It can be difficult to distinguish between small, powdery pollen grains. Credit: UTA Imagine just looking at your fingerprints and trying to separate yourself from the same twins. That’s how difficult it is for scientists to distinguish between the small, powdery pollen grains produced by fir, spruce and pine trees. However, new artificial intelligence systems developed by researchers at the…

Research provides a scaffolding to selectively target drug failure processes
Primary screen for CYP3A4. Credit: Natural Communication (2025). doi:10.1038/s41467-025-58749-8 Cytochrome P450 (CYP) protein degrades more than 80% of all Food and Drug Administration (FDA) approved drugs, reducing their efficacy. However, how to prevent CYP from doing this without target off effects has previously been confusing researchers. Scientists at St. Jude Children’s Research Hospital have designed a new drug framework that…

Research warns that carbon dioxide rate of rise is ‘incompatible’ with 1.5℃ target
Credit: Unsplash/CC0 Public Domain Carbon dioxide in the atmosphere is increasing at a rate that is incompatible with keeping global warming below 1.5 degrees Celsius (34.7 degrees Fahrenheit), a Japan Meteorological Agency study warns. Concentrations of major greenhouse gases rose in 2024 at the fastest annual level in a long-term record of measurements at Hawaii’s Mauna Loa, which dates back…
