A connection between time-varying networks and transport theory opens prospects for developing predictive equations of motion for networks.

Many real-world networks change over time. Think, for example, of social interactions, gene activation in a cell, or strategy making in financial markets, where connections and disconnections occur all the time. Understanding and anticipating these microscopic kinetics is an overarching goal of network science, not least because it could enable the early detection and prevention of natural and human-made disasters. A team led by Fragkiskos Papadopoulos of Cyprus University of Technology has gained groundbreaking insights into this problem by recasting the discrete dynamics of a network as a continuous time series [1] (Fig. 1). In doing so, the researchers have discovered that if the breaking and forming of links are represented as a particle moving in a suitable geometric space, then its motion is subdiffusive—that is, slower than it would be if it diffused normally.

Humanity is on the verge of entering a new era of space exploration, with the Artemis III mission planning to return humans to the moon in 2026, for the first time in 50 years. Not only will Artemis see a woman and a person of color walk on the lunar surface for the first time, but the week-long mission to the south pole of the moon will begin a period of longer and longer stays in space.

Grapene’s unusually high conductivity and favorable mechanical properties could further the development of flexible electronics, new batteries, and innovative composite materials for aeronautics and space flight. However, the development of elastic and tough films remains a challenge.

In the journal Angewandte Chemie (“A Stretchable and Tough Graphene Film Enabled by Mechanical Bond”), a research team has now introduced a method to overcome this hurdle: they linked graphene nanolayers via “extendable” bridging structures.

Cartoon representations of the fabrication process of RBG films and toughening mechanism of mechanical bond. Upon applied force, the hidden chain of [2]rotaxane was released due to intramolecular motion, resulting in an increased interlayer slip distance. It follows that the mechanical performance of RBG films were improved when mechanical bond was introduced.

If you are a fan of reading or watching science fiction, you have definitely encountered the concept of curvature propulsion — one of the most fascinating and speculative frontiers in theoretical physics and advanced space travel.

Rooted in Einstein’s general theory of relativity, it proposes innovative methods to manipulate spacetime itself to achieve faster-than-light travel without violating the laws of physics.

General relativity, formulated by Albert Einstein, provides the theoretical foundation for curvature propulsion. This theory describes gravity as the curvature of spacetime caused by mass and energy.

New astrophysical research highlights a significant cosmic event two million years ago when the solar system passed through a dense interstellar cloud. This possibly altered Earth’s climate by exposing it to enhanced cosmic radiation, supported by increased isotopes found in geological records.

Earth was a very different place around two million years ago, with our early human ancestors living alongside saber-toothed tigers, mastodons, and enormous rodents. And, depending on where they were, they may have been cold: Earth had fallen into a deep freeze, with multiple ice ages coming and going until about 12,000 years ago. Scientists theorize that ice ages occur for a number of reasons, including the planet’s tilt and rotation, shifting plate tectonics, volcanic eruptions, and carbon dioxide levels in the atmosphere.

But what if drastic changes like these are not only a result of Earth’s environment, but also the sun’s location in the galaxy?

The agency will spend 100 trillion won ($72 billion USD) in build-up to planned 2045 Mars landing.

This will enable us to increase our production rate significantly as we build toward our long-term goal of producing one Ship per day.
