Complex fluid dynamics may explain hydroplaning
When a vehicle travels over a wet or flooded road, water builds up in front of the tire and generates a lift force. In a phenomenon known as hydroplaning, this force can become large enough to lift the vehicle off the ground......»»
Halide developers detail how new Process Zero feature works under the hood
The popular iPhone and iPad camera app Halide recently introduced a new feature called Process Zero which, as the name suggests, takes photos without all the modern post-processing of smartphone cameras. The developers behind the app have now explain.....»»

Observatory reveals key evidence of cosmic ray acceleration limit in W51 for first time
The Large High Altitude Air Shower Observatory (LHAASO) officially released the precise measurements of high-energy gamma radiation from the W51 complex, confirming it as a cosmic-ray accelerator boosting particles up to so-called ultra-high energies.....»»
Machine-learning models can predict colonization outcomes of complex microbial communities
Microbial communities are constantly exposed to the invasion of exogenous species, which can significantly alter their composition and function. The capacity of a microbial community to resist invasion is regarded as an emergent property resulting fr.....»»
Upgraded atomic force microscope captures 3D images of calcite dissolving
Understanding the dissolution processes of minerals can provide key insights into geochemical processes. Attempts to explain some of the observations during the dissolution of calcite (CaCO3) have led to the hypothesis that a hydration layer forms, a.....»»
Supercomputer simulations reveal the nature of turbulence in black hole accretion disks
Researchers at Tohoku University and Utsunomiya University have made a breakthrough in understanding the complex nature of turbulence in structures called accretion disks surrounding black holes, using state-of-the-art supercomputers to conduct the h.....»»
Concord’s rocky launch is less complicated than you think
Players are jumping through hoops to explain why Sony's Concord is struggling to get off the ground, but maybe the explanation is simpler than it seems......»»
Using high resolution mass spectrometry to study fuel chemistry

DNA replication in early embryos differs from previous assumptions, study shows
A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the experiments published August 28 in Nature show that DNA repl.....»»
Breaking open the AI black box, team finds key chemistry for solar energy and beyond
Artificial intelligence is a powerful tool for researchers, but with a significant limitation: the inability to explain how it came to its decisions, a problem known as the "AI black box.".....»»
New Lexus brand "taste" will come from sweeping rework of body rigidity
Lexus says it has found the missing piece in its quest to match the long-lauded driving dynamics of Germany's big premium players — better body rigidity. To deliver a better signature, Toyota's top-shelf marque is reworking ride and handling across.....»»
Dissecting caspase-2-mediated cell death: From intrinsic PIDDosome activation to chemical modulation
Caspase-2, an initiator caspase, plays a critical role in programmed cell death in response to certain cellular stresses. Its activation is facilitated by the PIDDosome, a multi-protein complex that assembles under conditions of genotoxic stress. Des.....»»
Unlocking crop yield potential: New modeling approach for sustainable agriculture
Predicting crop yields is a significant challenge in modern agriculture, especially under fluctuating environmental conditions. With the escalating demand for sustainable food production, understanding the complex interplay between environmental fact.....»»
Hybrid imaging approach reveals microbes in 3D
Caltech researchers have developed a new method to create three-dimensional images of complex communities of bacteria and plant roots. The technology synthesizes two traditional methods of imaging: visualizing microbes with fluorescence and a noninva.....»»
The Quantum Mechanics of the Greenhouse Effect
Carbon dioxide’s powerful heat-trapping effect has been traced to a quirk of its quantum structure. The finding may explain climate change better than any computer model......»»
Study highlights new advancements to simulate multiscale coastal processes
Simulating flooding where rivers meet the ocean is challenging because existing Earth system models struggle to capture the complex interactions between river flows, ocean tides, and storm surges......»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
