Protein folding mystery solution: research explains core packing fractions
Credit: PRX Life (2025). doi:10.1103/prxlife.3.013018 In organisms, all proteins (a type of biological polymer composed of hundreds of amino acids) remove certain functions such as catalysts, molecular transport, and DNA repair. To perform these functions, you must fold it into a specific shape. This is an important and complicated process in life, and despite advances in this field, many unanswered…

Core samples from the seabed in Greenland provide the first historical overview of plastic pollution
Map of Egedesminde DYB’s Disco Bay and sampling site. Credit: Communications Earth & Environment (2024). doi:10.1038/s43247-024-01768-y By filling the 850m deep seabed in Disco Bay off the west coast of Greenland, researchers at the University of Copenhagen have won the first historical record of plastic pollution in Greenland. The new data suggest links to local socioeconomic development and represent steps…

Research studies reveal core principles of low-resistant antibiotics
Laboratory pathogenic bacterial culture. Credit: Elvin Maharamov Research published in Nature Communications reveals new insights into bacterial resistance and provides promising strategies for developing antibiotics that minimize the evolution of resistance. Csaba Pal, D.Sc. At the Hun-Ren Biological Research Center in Hungary, the researchers demonstrated that a dual-target approach, combining membrane disruption and additional important cellular pathways, significantly prevents the…

The double magical core of the Lead-208 goes against expectations with its amazing shape properties
Experimental setup to study Double Magic Lead-208. Credit: Argonne National Laboratory. anl.gov/article/welcome-back-gretina. In a surprising event, an international team of scientists discovered that the heaviest known “double magic” nucleus, Lead-208 (208pb), exhibits unexpected geometric properties that current nuclear models cannot be accurately predicted. Double magic refers to a nucleus with a full shell of both protons (82) and neutrons (126).…

Study identifies superionic iron hydride as key to ultra-low velocity zone at the boundary between Earth’s core and mantle
Mean square displacements (MSD) of Fe and H atoms in fcc-FeH at different temperatures and volumes from NVT-FPMD simulations. The core-mantle boundary (CMB) is a key boundary within the Earth, marking the boundary between the outer core and the lower mantle. Over the past two decades, seismological studies have identified anomalously low-velocity regions above the CMB, such as the Large-Scale…
