Inter-satellite link (ISL) plays an essential role in current and future Global Navigation Satellite System (GNSS). A recent study, conducted by Wuhan University's GNSS Research Center and published in Satellite Navigation in May 2024, explored the significant effect of ISL data on the orbital characteristics of the BDS-3 MEO satellites.

In December, the New England Journal of Medicine began a process of self-examination, publishing articles about the journal itself and its handling of a series of key historical injustices in medicine, including eugenics, slavery, oppression of Native Americans, and, in an issue published in April, the rise of Nazi Germany.

Kenya's worst flooding in decades highlights the urgent need for more robust mitigation efforts, including flood risk maps and early warning systems, say climate scientists.

In Finland, the European spruce bark beetle prefers mature Norway spruce forests close to recent clear-cut sites, a new study from the University of Eastern Finland finds.

As the world grapples with the urgent need to reduce greenhouse gas emissions, there is a growing interest in understanding how individual actions can contribute to this goal. The complexity and scale of energy use and carbon emissions data can be overwhelming for the average person, often leading to a disconnect between daily activities and their environmental impact.

It's tiny, but it's there. By now, we're all used to seeing amazing photos of Jupiter courtesy of NASA's Juno mission on a routine basis. Many of these are processed by volunteer "citizen scientists," and they show the swirling cloud-tops of Jove courtesy of the spacecraft's JunoCam in stunning detail.

How many ponds should we create? What should they look like? And where is a good location? These are the questions most frequently asked by nature conservation experts when it comes to protecting amphibians.

When members of a group successfully coordinate their movements with one another, this leads to a stronger sense of togetherness. This was shown by a recent study by the Universities of Würzburg and Regensburg.

Medical research is increasingly informed by recognition of diversity's key role in addressing health equity. But when it comes to medical education, there's a group that has remained not just underrepresented but also under-researched: first-generation (first-gen) medical students—those whose parents have not earned bachelor's degrees.

A new process developed at Cornell AgriTech can produce antioxidant-rich cold-pressed Concord grape juice with a longer shelf life, meeting rising demand for minimally processed juices that are tastier and more nutritious.

Research conducted in Brazil at the Center for Development of Functional Materials (CDMF) and the Center for Innovation in New Energies (CINE) has developed a novel approach to the plasma treatment of antimony tri-selenide (Sb2Se3) films that makes their surface hydrophilic, i.e. attracted to water molecules and easily dissolved by water, instead of hydrophobic (repelled by water).

The increasing sense of environmental responsibility of both consumers and companies has triggered a transition towards alternative materials which are perceived as more sustainable than plastics.

Researchers at the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany, have analyzed the evolutionary development of symbiotic bacteria in the intestines of termites with regard to their metabolic capabilities.

AI-generated videos for short messages are only as well received as manually created ones if they are edited by humans.

Thermoelectric materials could play an important role in the clean energy transition, as they can produce electricity from sources of heat that would otherwise go to waste without generating additional greenhouse gases or requiring large up-front investment. But their promise has been slowed by the fact that most current thermoelectric materials don't efficiently produce enough power to be useful for many practical applications.

Outdoor air pollutants monitored at five Queensland schools in a year-long QUT study found that most of the tiny particles (PM2.5) that lodge in the lungs came from the environment, such as smoke from controlled burns, rather than vehicles.

Worldwide news media are facing increasing pressure from autocrats to report favorably about their leaders and party politics, so political scientists have launched a new computational method that can detect such media censorship by states while it is happening. This method provides valuable insights for communicating regime-driven media capture to the public. It is now described in detail in an article published in the journal Democratization.

BepiColombo, the joint ESA/JAXA mission to Mercury, has experienced an issue that is preventing the spacecraft's thrusters from operating at full power.

Our diet puts a strain on planetary resources. Shifting to a sustainable diet that benefits both our health and that of the planet is therefore assuming increasing importance. Researchers at the University of Bonn have analyzed the diets of children and adolescents in terms of their contribution to the ecological sustainability indicators of greenhouse gas emissions, land use and water use.
