Planetary 'twins' Uranus and Neptune may have different origin stories

By indirectly probing the depths of Uranus and Neptune's atmospheres, an international team of scientists has revealed a significant contrast in their chemical composition. Neptune appears to be more enriched in oxygen than Uranus. These results suggest that the two ice giants may have formed in different regions of the primitive solar system before reaching their current orbits, calling into question the idea of a common origin for these two planets, often considered twins.

Researchers unlock new way to map molecular structure on surfaces

Scientists at NPL, with the University of Surrey, University of Oxford, the Francis Crick Institute and IONTOF GmbH, have developed a technique to distinguish and map molecules that share the same chemical formula and mass but have different structures and functions. The research is published today (Oct. 19) in Nature Communications.

Who speaks for Mars? Scientists call for ethical debate before terraforming begins

Transforming Mars into a more Earth-like world could irreversibly destroy scientific evidence about the planet's history and the possibility of extraterrestrial life. In an opinion article published in Eos, a team of Dutch, French and U.S. planetary scientists and ethicists warns that humanity risks destroying Mars' scientific record before it has been fully explored.

Synthetic molecules self-assemble into triple helices with new control method

Researchers at the University of Jyväskylä, Finland, have developed a new strategy for programming synthetic molecules to self-assemble into precisely defined three-dimensional structures. The study brings scientists a step closer to achieving the sophisticated molecular organization found in nature and could eventually open new possibilities for the development of advanced functional materials.

Birds are among Earth's most important nutrient movers

Birds play an outsized, underappreciated role in shaping Earth's chemistry, distributing nutrients across oceans, forests and coral reefs and sustaining life far beyond the nest. Researchers from Cornell and five other institutions reviewed nearly 400 scientific papers to show how birds transport nutrients from land, lake and sea through their waste and bodies. This influences everything from soil and water chemistry to plant and animal growth. The work was published Oct. 19 in Current Biology.

The hidden global market behind recycling revealed

Recycling may happen far from the place where waste is produced. Paper, metals, plastics and glass discarded in one country can be shipped across the world and used as raw materials in another. This international market is a major part of today's circular economy, yet it is often overlooked when national recycling policies are designed.

New wheat disease detection tool established in Tanzania

John Innes Centre researchers have trained scientists from across Tanzania to use new loop-mediated isothermal amplification (LAMP) assays to rapidly detect wheat blast, a looming fungal threat to wheat harvests.
