Field-particle energy transfer during chorus emissions in space.
Nature
January 2025
Southwest Research Institute, San Antonio, TX, USA.
Chorus waves are some of the strongest electromagnetic emissions naturally occurring in space and can cause radiation that is hazardous to humans and satellites. Although chorus waves have attracted extreme interest and been intensively studied for decades, their generation and evolution remain highly debated. Here, in contrast to the conventional expectation that chorus waves are governed by planetary magnetic dipolar fields, we report observations of repetitive, rising-tone chorus waves in the terrestrial neutral sheet, where the effects of the magnetic dipole are absent.

Objective: We aim to assess which variables are associated with recruitment failure of obstetrical and gynaecological randomised controlled trials (RCTs), leading to an extension of the study period.
Design: Nationwide study.
Setting: A cohort of RCTs supported by the trial centre of the Dutch Consortium of Obstetrics and Gynaecology.
Efficient removal of cationic malachite green using co-pyrolyzed corn straw biochar-montmorillonite composites.

Department of Civil and Environmental Engineering, Rensselaer Polytechnic Institute, Troy, NY, 12180, USA.
New efficient and sustainable methods for the removal of malachite green (MG) from environmental media are needed. In this study, corn straw was co-pyrolyzed with montmorillonite under a variety of conditions (400, 500, 600, and 700 °C and 10-40 wt% montmorillonite), without any use of toxic chemicals, to produce a series of biochar-clay composites. Characteristics of the composites that make them promising contaminant sorbents include a uniform lamellar-particle micromorphology, enhanced mesoporous structure and surface area (53.

Background: Hepatocellular carcinoma (HCC) encompasses rare variants like chromophobe hepatocellular carcinoma (CHCC) characterized by distinct histological features and molecular profiles.
Case Report: A 56-year-old male with chronic hepatitis C, presenting pain in the right hypochondrium. Imaging revealed a solitary liver lesion, subsequently resected and histologically diagnosed as HCC.
Assessing foraging landscape quality in Quebec's commercial beekeeping through remote sensing, machine learning, and survival analysis.

Honey bees (Apis mellifera) play an important role in our agricultural systems. In recent years, beekeepers have reported high colony mortality rates in several parts of the world. Inadequate foraging landscapes are often cited as a major factor deterring honey bee colony health.
