New parameterization method for cislunar space cataloging enhances orbital awareness in Earth-Moon system
2026-01-13
As lunar exploration intensifies, the cislunar space is experiencing increasing congestion. Traditional two-body Keplerian elements, which have long been the standard for Earth-orbiting objects, prove insufficient for accurately describing the complex orbits near the Earth–Moon Lagrange points due to the chaotic and non-integrable nature of three-body dynamics. This fundamental deficiency has hindered the development of an effective space situational awareness (SSA) framework for this strategically vital region. A research team from the National University of Defense Technology (NUDT) ...
A “nu” way to measure researcher impact
2026-01-13
Researchers propose a new citation index that balances productivity and impact in academic publishing. The h-index of citations was introduced in 2005 by a physicist Jorge E. Hirsch. This index is defined simply as the maximum number h of an author’s published papers with at least h citations each. For example, h = 3 means that there are three papers with 3 or more citations, but if a fourth paper exists, it has fewer than four citations. The h-index has quickly gained popularity and is now widely used to measure productivity ...

Manuel Leonetti, Rafael Gómez-Sjöberg, and colleagues developed the Automated Cell Culture Splitter, an open-source robotic system built around the Opentrons OT-2 liquid handling robot equipped with a custom cell counting imaging instrument. The system automates passaging—the transfer of cells from one culture plate to another when they grow too numerous—of either adherent or suspended cells in 96-well plates, a process conventionally requiring tedious manual work. The authors tested the system with a commonly ...
Fathers’ health influences offspring through sperm RNAs
2026-01-13
A study in mice on small RNAs in sperm helps explain how the health of fathers can influence the health of their offspring. Bin He and colleagues explored how paternal immune activation in mice affects a specific class of small RNAs in sperm, known as 28S-rsRNAs. Mice were injected with lipopolysaccharides derived from the bacteria Escherichia coli, to prompt an immune response. A week later, the mice were found to have fewer sperm and an increased number of 28S-rsRNAs in what sperm they did have. Notably, these effects largely subsided six weeks post-injection—spanning ...

Recovering tropical forests grow back nearly twice as fast with nitrogen
2026-01-13
Young tropical forests play a crucial role in slowing climate change. Growing trees absorb carbon dioxide from the air, using photosynthesis to build it into their roots, trunks, and branches, where they can store carbon for decades or even centuries. But, according to a new study, this CO2 absorption may be slowed down by the lack of a crucial element that trees need to grow: nitrogen.
Published in Nature Communications and coauthored by Cary Institute of Ecosystem Studies ecologist Sarah Batterman, the study estimates that ...
