The big emitters: the United States

The United States, the world's second largest emitter of greenhouse gases, has pledged to halve its emissions by 2030 compared to 2005 levels—but so far is failing to stay on target, analysts say.

Webb captures a prominent protostar in Perseus

This new Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope reveals intricate details of the Herbig Haro object 797 (HH 797). Herbig-Haro objects are luminous regions surrounding newborn stars (known as protostars), and are formed when stellar winds or jets of gas spewing from these newborn stars form shockwaves colliding with nearby gas and dust at high speeds.

Two synthetic molecules developed to help elucidate cellular functions

A sugar-based molecule naturally produced by the body can help cells grow, differentiate into different types, self-destruct if need be and much more. It helps protect the cell's genome, repair DNA, and regulate how genes are passed down. The molecule, called poly(adenosine diphosphate ribose) or poly(ADP-ribose), can potentially inform disease prevention and treatments—if scientists can figure...

Minerals and land use determine carbon storage in soils, finds study

Carbon sequestration in soils can contribute to mitigate climate change, and soil organic matter associated with minerals has the highest capacity to store carbon. A team of researchers, including scientists from the Max Planck Institute for Biogeochemistry and the Martin Luther University Halle-Wittenberg, assessed the factors controlling mineral-associated organic matter.

Revolutionizing water safety: New study makes tap water cleaner and safe

In a new study published in the journal Frontiers of Environmental Science & Engineering, researchers from University of Toronto identified the most effective and practical quenching agent for use in drinking water treatment plants. The findings emphasize the crucial significance of selecting an appropriate quenching agent, a decision that plays a key role in the context of drinking water...

Hydrogels show promise as a new way to deliver drugs more efficiently

Many of the most promising new pharmaceuticals coming along in the drug development pathway are hydrophobic by nature—that is, they repel water, and are thus hard to dissolve in order to make them available to the body. But now, researchers at MIT have found a more efficient way of processing and delivering these drugs that could make them far more effective.

Film and TV production found to worsen climate crisis

Streaming giants are making TV production worse for the environment than ever before according to new research into the environmental impact of film and television production from the University of Warwick and the University of Cambridge. One Hollywood film creates around 3,000 tons of carbon, the equivalent of driving around the world almost 300 times.
