Titan, Saturn's largest natural satellite, captivates scientists with its Earth-like processes, dense nitrogen atmosphere, and surface lakes of liquid hydrocarbons. However, its nonuniform gravity field, thick haze, and low solar energy pose major obstacles for orbital missions. Traditional single-satellite systems struggle to balance coverage, stability, and data transmission under such conditions. Moreover, the gravitational pull from Saturn and nearby moons further complicates orbital control.

For the first time, researchers at the Technical University of Munich (TUM) have succeeded in using nanorobots to stimulate stem cells with such precision that they are reliably transformed into bone cells. To achieve this, the robots exert external pressure on specific points in the cell wall. The new method offers opportunities for faster treatments in the future.

A research team at the Jülich Supercomputing Center, together with experts from NVIDIA, has set a new record in quantum simulation: for the first time, a universal quantum computer with 50 qubits has been fully simulated—a feat achieved on Europe's first exascale supercomputer, JUPITER, inaugurated at Forschungszentrum Jülich in September.

The furious push by AI hyperscalers to build out data centers will need about $1.5 trillion of investment-grade bonds over the next five years and extensive funding from every other corner of the market, according to an analysis by JPMorgan. From a report: "The question is not 'which market will fin...

During winter months, frost can unleash icy havoc on cars, planes, heat pumps, and much more. But thermal defrosting with heaters is very energy intensive, while chemical defrosting is expensive and toxic to the environment.

Viscous fingering occurs when a thinner fluid pushes a thicker, more viscous fluid in a porous medium, like underground rock, creating unpredictable, finger-like patterns. For decades, this intricate dance between fluids has been a major headache in critical sectors like enhanced oil recovery, CO2 sequestration, and groundwater remediation. Predicting and controlling these "fingers" has remained an elusive goal for scientists, largely due to the sheer complexity of the fluid dynamics involved.

A novel technology that utilizes light of different wavelengths to control cellular functions by inducing reversible assembly and disassembly of molecules has been developed. This breakthrough could pave the way for new approaches in treating superficial cancers, such as skin cancer, as well as serving as a powerful molecular tool for fundamental life science investigations.

Work continues on designs for robots that can help assist the first human explorers on the moon in over half a century. One of the most important aspects of that future trip will be utilizing the resources available on the moon's surface, known as in-situ resource utilization (ISRU). This would give the explorers access to materials like water, structural metals, and propellant, but only if they can recover it from the rock and regolith that make up the moon's surface.

Before atomic elements came together, less than a second after the Big Bang, if particles condensed into halos of matter, these halos may then have collapsed, creating the first black holes, boson stars, and so-called cannibal stars. This is the conclusion of a new study just published in Physical Review D, conducted by a team of researchers from SISSA—Scuola Internazionale Superiore di Studi Avanzati, in collaboration with INFN, IFPU, and the University of Warsaw.

A globally cited statistic about the role of irrigation for food security that has formed foundational evidence for policy-making and scientific research is used on a hearsay basis and is based on weak evidence, according to a new study.

NIMS has been developing chemical sensors as a key component of artificial olfaction technology (olfactory sensors), with the aim of putting this technology into practical use. In a new study, explainable AI (XAI) was used to reveal how chemical sensors discriminate among various odorant molecules. The findings may help guide the selection of receptor materials for developing high-performance chemical sensors capable of detecting odorant molecules.

Quantum computers, machines that process information leveraging quantum mechanical effects, could outperform classical computers on some optimization tasks and computations. Despite their potential, quantum computers are known to be prone to errors and their ability to perform computations is easily influenced by noise.

Models help scientists understand everything from the particles that make up the universe to massive superstructures of galaxies at the beginning of time. But sometimes they model more mundane, though perhaps even more complex, features—including the course of human civilization. A new paper by Thomas Leppard of the International Archaeological Research Institute and his co-authors, all of whom are also archaeologists, proposes applying a model of how humans expanded to the different islands across the Pacific Ocean during their early migration to glean insights into how humanity should manage our colonization of space.

As a true milestone on the path to autonomous space systems, a research team at Julius-Maximilians-Universität Würzburg (JMU) has successfully tested an AI-based attitude controller for satellites directly in orbit—a world first. The test was carried out aboard the 3U nanosatellite InnoCube.

The PDF Association is adding JPEG XL (JXL) support to the PDF specification, giving the advanced image format a new path to relevance despite Google's decision to declare it obsolete and remove it from Chromium. The Register reports: Peter Wyatt, CTO of the PDF Association, said: "We need to adopt...

Japan's Innovation Center of NanoMedicine reports on a new stealth coating for tiny medicine-carrying particles that doesn't depend on PEG-style shields. By locking positive and negative charges together into a tight net, the coating prevents protein buildup and avoids pickup by immune cells, so the particles stay in the blood for more than 100 hours. Packed with the enzyme asparaginase, the particles act like small reactors that drain asparagine to starve difficult-to-treat cancers.

An anonymous reader quotes a report from Reuters: Privacy activists say proposed changes to Europe's landmark privacy law, including making it easier for Big Tech to harvest Europeans' personal data for AI training, would flout EU case law and gut the legislation. The changes proposed by the Europea...

A team led by University of Pittsburgh's Graham Hatfull has developed a method to construct bacteriophages with entirely synthetic genetic material, allowing researchers to add and subtract genes at will. The findings open the field to new pathways for understanding how these bacteria-killing viruses work, and for potential therapy of bacterial infections.
