Gravity study gives insights into hidden features beneath lost ocean of Mars and rising Olympus Mons

Posted by in categories: government, space

Studies of gravity variations at Mars have revealed dense, large-scale structures hidden beneath the sediment layers of a lost ocean. The analysis, which combines models and data from multiple missions, also shows that active processes in the Martian mantle may be giving a boost to the largest volcano in the solar system, Olympus Mons. The findings have been presented this week at the Europlanet Science Congress (EPSC) in Berlin by Bart Root of Delft University of Technology (TU Delft).

Using machine learning to uncover predictors of well-being

Posted by in categories: genetics, neuroscience, robotics/AI

Irrespective of their personal, professional and social circumstances, different individuals can experience varying levels of life satisfaction, fulfillment and happiness. This general measure of life satisfaction, broadly referred to as “well-being,” has been the key focus of numerous psychological studies.

Better understanding the many factors contributing to well-being could help to devise personalized and targeted interventions aimed at improving people’s levels of fulfillment. While many past studies have tried to delineate these factors, few have done so leveraging the advanced machine learning models available today.

Machine learning models are designed to analyze large amounts of data, unveiling hidden patterns and making . Using these tools to analyze data collected in previous studies in neuroscience and psychology could help to shed light on the environmental and influencing well-being.

Findings from experimental setup demonstrate potential for compact and portable nuclear clocks

Posted by in category: particle physics

Scientists use atomic clocks to measure the “second,” the smallest standard unit of time, with great precision. These clocks use natural oscillations of electrons in atoms, similar to how pendulums work in old grandfather clocks. The quest for an even more precise timekeeper led to the discovery of nuclear clocks, which use the transitions of atomic nuclei instead of electrons to keep time.

Generating spin currents directly using ultrashort laser pulses

Posted by in category: physics

An international team of physicists has found that it is possible to generate spin currents directly using certain kinds of ultrashort laser pulses. In their study, published in the journal Physical Review Letters, the group used a linearly polarized laser pulse and a circularly polarized probe laser to create the spin currents.

Sony says the PS5 Pro uses next-gen AMD ray tracing tech — likely RDNA 4

Posted by in category: computing

Something to look forward to: Improved ray tracing performance is one of the key benefits of Sony’s newly unveiled PlayStation 5 Pro console. Prior to its debut, rumors had long suggested that the mid-generation refresh would incorporate ray tracing technology based on AMD’s upcoming RDNA 4 GPU architecture. Recent comments from PlayStation designer Mark Cerny have all but confirmed these theories.

In a detailed interview with CNET following the reveal of Sony’s PlayStation 5 Pro console, designer Mark Cerny confirmed rumors that the device’s ray tracing capabilities are built on an architecture not yet available in AMD’s PC graphics cards. While Cerny didn’t explicitly name RDNA 4, no other viable candidates are known.

Smart supramolecular assemblies: Researchers show how additives promote self-assembly of spherical microparticles

Posted by in categories: biotech/medical, chemistry

If you’ve ever opened a box from IKEA and wished the pieces inside could somehow spontaneously merge to form a table or chair, then a simple virus could have a thing or two to teach you. Self-assembly of complex molecules is essential for a wide array of biological structures, including proteins, cell membranes, or even entire viruses. Supramolecular chemistry is a field of study that attempts to build large molecules out of a discrete number of…

Astronomers Discover a Rare Black Hole That Defies Astrophysical Theories

Posted by in category: cosmology

Chinese astronomers have uncovered a low-mass black hole that challenges long-held astrophysical theories. This black hole, part of a binary system known as G3425, has a mass of about 3.6 solar masses, placing it in the elusive mass-gap where black holes were previously thought to be absent. The discovery was made using a combination of radial velo…
