Can one single mathematical framework describe the motion of a fluid and the individual particles within it? This question, first asked in 1900, now has a solution that could help us understand the complex behaviour of the atmosphere and oceans.

With artificial photosynthesis, humankind could utilize solar energy to bind carbon dioxide and produce hydrogen. Chemists have taken this one step further: They have synthesized a stack of dyes that comes very close to the photosynthetic apparatus of plants. It absorbs light energy, uses it to separate charge carriers and transfers them quickly and efficiently in the stack.

Researchers have experimentally recreated another fundamental theoretical model from quantum physics, which goes back to the Nobel Prize laureate Werner Heisenberg. The basis for the successful experiment is made of tiny carbon molecules known as nanographenes. This synthetic bottom-up approach enables versatile experimental research into quantum technologies, which could one day help drive breakthroughs in the field.

Iridium-doped iron-cobalt (Fe-Co-Ir) alloys, previously identified through machine learning, have been shown to have enhanced magnetic properties, surpassing even the widely used pure Fe-Co alloy. However, the origin of this enhanced magnetization is poorly understood. Now, scientists employed an innovative method using high-throughput X-ray magnetic circular dichroism (XMCD) measurements, demonstrating the critical role of Ir-doping. The findings will serve as a foundation for designing new high-performance magnetic materials.

Astronomers have discovered two exoplanets around TOI-1453, a star about 250 light years away. These two exoplanets, a super-Earth and a sub-Neptune, are common in the galaxy, yet are absent from our system. This discovery paves the way for future atmospheric studies to better understand these types of planets.

Digital voice recordings contain valuable information that can indicate an individual's cognitive health, offering a non-invasive and efficient method for assessment. Research has demonstrated that digital voice measures can detect early signs of cognitive decline by analyzing features such as speech rate, articulation, pitch variation and pauses, which may signal cognitive impairment when deviating from normative patterns. However, voice data introduces privacy challenges due to the personally identifiable information embedded in recordings, such as gender, accent and emotional state, as well as more subtle speech characteristics that can uniquely identify individuals. These risks are amplified when voice data is processed by automated systems, raising concerns about re-identification and potential misuse of data.

A failed launch left a batch of Starlink satellites in the wrong orbit last year, and it appears that a fragment of one fell to Earth and hit a farm in Canada. Thankfully, no one was injured

Solar Power Satellite (SPS) advocates have been dreaming of using space resources to build massive constructions for decades. In-space Resource Utilization (ISRU) advocates would love to oblige them, but so far, there hasn't yet been enough development on either front to create a testable system. A research team from a company called MetaSat and the University of Glasgow hope to change that with a new plan called META-LUNA, which utilizes lunar resources to build (and recycle) a fleet of their specially designed SPS.

New Scientist's revelation that a UK minister is asking ChatGPT for advice raises the question of what role these new AI tools should play in government – and whether we should really think of them as intelligent

It can be difficult to recall exactly when a specific event happened, and now it seems our memory can be tricked into pushing occurrences back in time, making us think they happened earlier than in reality

In a survey of AI researchers, most say current AI models are unlikely to lead to artificial general intelligence with human-level capabilities, even as companies invest billions of dollars in this goal

These brilliant images show how researchers in Switzerland are using weather-modification techniques to understand how ice crystals form in clouds, an important and poorly understood factor in climate and weather models

An analysis of changes to global ecosystems has revealed that almost nowhere is untouched by the influence of humanity, with more than 50 per cent of the planet's land mass experiencing "novel" conditions

Building the full value of pi has been a project thousands of years in the making, but just how much of this infinite number do we actually need, asks our maths columnist Jacob Aron

I only feel comfortable suggesting an RCT of routine vaccines because I am confident it wouldn't get off the ground.

The post RFK Jr: Recruit Dr. Vinay Prasad to Run an RCT of the Routine Vaccine Schedule first appeared on Science-Based Medicine.

JWST Cycle 4 Spotlight, Part 1: Exoplanets and Habitability

A distant trio of worlds may shed light on planetary formation in the early solar system. Sometimes, good things come in threes. If astronomers are correct, a system in the distant Kuiper Belt may not be two but three worlds, offering an insight into formation in the early solar system. The study comes out of researchers at Brigham Young University and the Space Telescope Science Institute.
