Cloud band movement influences wet spells during Indian monsoon

Indian Institute of Science (IISc)
Peer-Reviewed Publication

The strength of the equatorial cloud band plays a key role in its movement upward and intensity of wet spells during the Indian monsoon, study finds.

Researchers achieve de novo biosynthesis of plant lignans using synthetic yeast consortia

Dalian Institute of Chemical Physics, Chinese Academy Sciences
Peer-Reviewed Publication

A research group led by Prof. ZHOU Yongjin from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, collaborating with researchers from the Naval Medical University, has achieved the biosynthesis of the antiviral ingredient lignan glycoside in yeast Saccharomyces cerevisiae.

A new benchmark for the quantum electrodynamics in atoms

Max-Planck-Institut fur Kernphysik
Peer-Reviewed Publication

The g factor of boron-like tin ions is determined with an uncertainty of only 0.5 parts per billion. The second high-precision measurement for a ground-state boron-like system at all sets a new benchmark for quantum electrodynamics as well as multiple-electron interactions in heavy systems. Combining the new results with the recent electron g-factor measurement of hydrogen-like tin provides a potential for an independent determination of the fine-structure constant α.

The secret behind pedestrian crossings – and why some spiral into chaos

University of Bath
Peer-Reviewed Publication

Neat lanes are the norm at road crossings – until people start veering off at critical angles, then chaos ensues. New maths discovery has the potential to help planners design road crossings and other pedestrian spaces that minimise chaos and enhance safety and efficiency.

Organic molecules of unprecedented size discovered on Mars

CNRS
Peer-Reviewed Publication

The longest organic molecules identified to date on Mars have recently been detected by scientists from the CNRS¹, together with their colleagues from France, the United States of America, Mexico and Spain. These long carbon chains, containing up to 12 consecutive carbon atoms, could exhibit features similar to the fatty acids produced on Earth by biological activity². The lack of geological activity and the cold, arid climate on Mars have helped preserve this invaluable organic matter in a clay-rich sample for the past 3.7 billion years. It therefore dates from the period during which life first emerged on Earth. These findings are due to be published on March 24^th 2025 in the journal PNAS.

3D nanotech blankets offer new path to clean drinking water

Ohio State University
Peer-Reviewed Publication

Researchers have developed a new material that, by harnessing the power of sunlight, can clear water of dangerous pollutants.

"Mars and Earth are even more different than we thought": researchers from the Faculty of Sciences publish groundbreaking study on Martian observations

Faculty of Sciences of the University of Lisbon
Peer-Reviewed Publication

For the first time on a global scale, 20 years of observations on Mars have been condensed into a single study led by Francisco Brasil and Pedro Machado, both researchers from the Faculty of Sciences at the University of Lisbon (CIÊNCIAS ULisboa). This study, an extensive and comprehensive analysis of the Red Planet’s atmospheric waves, has just been published in AGU (Advancing Earth and Space Science), a leading reference in astronomy and astrophysics.
