Deep learning underpins a wide range of applications in MRI, including reconstruction, artifact removal, and segmentation. However, progress has been driven largely by public datasets focused on brain and knee imaging, shaping how models are trained and evaluated. As a result, careful studies of the reliability of these models across diverse anatomical settings remain limited. In this work, we introduce MosaicMRI, a large and diverse collection of fully sampled raw musculoskeletal (MSK) MR measurements designed for training and evaluating machine-learning-based methods. MosaicMRI is the largest open-source raw MSK MRI dataset to date, comprising 2,671 volumes and 80,156 slices. The dataset offers substantial diversity in volume orientation (e.g., axial, sagittal), imaging contrasts (e.g., PD, T1, T2), anatomies (e.g., spine, knee, hip, ankle, and others), and numbers of acquisition coils. Using VarNet as a baseline for accelerated reconstruction task, we perform a comprehensive set of experiments to study scaling behavior with respect to both model capacity and dataset size. Interestingly, models trained on the combined anatomies significantly outperform anatomy-specific models in low-sample regimes, highlighting the benefits of anatomical diversity and the presence of exploitable cross-anatomical correlations. We further evaluate robustness and cross-anatomy generalization by training models on one anatomy (e.g., spine) and testing them on another (e.g., knee). Notably, we identify groups of body parts (e.g., foot and elbow) that generalize well with each other, and highlight that performance under domain shifts depends on both training set size, anatomy, and protocol-specific factors.

Learn why your hips feel stiff and how to fix it with these expert-recommended movements for maximum mobility. Breakthroughs, discoveries, and DIY tips sent six days a week. For the largest muscle group in the body, glutes get relatively little attention outside their cosmetic contributions. Bridges, squats, and kickbacks help develop size and shape, but they paint an incomplete picture; for total hip health and function, your regimen should include a wide variety of movements. This includes glute stretches that take your body's second-most mobile joint through its fullest possible range of motion. "Our hips are where we move from.

Tech companies may have lost their moral standing, but at least they added shareholder value. Elon Musk holds up a chainsaw onstage during the Conservative Political Action Conference (CPAC) in National Harbor, Maryland, U.S., February 20, 2025. Sure, we've seen millions poured into lobbying and other means of influence during every presidency, but the last two years set a whole new bar. Business leaders, including those from almost every Big Tech company, stepped over themselves to prove fealty to Donald Trump's second administration. It's easy to see why: Their kowtowing was meant to secure regulatory favors, gain tax and tariff advantages and avoid Trump's ire.

The Trump administration's pressure on European regulators is having an impact, with fewer restrictions on Big Tech and canceled measures. Almost everything is on hiatus. The EU AI Act, Digital Services Act, and Digital Markets Act are all at risk. The European Commission is preparing to end the year with virtually no movement on its most important tech policy initiatives. Many measures may even be reversed.

Bipedal balance is challenging due to its multi-phase, hybrid nature and high-dimensional state space. Traditional balance control approaches for bipedal robots rely on low-dimensional models for locomotion planning and reactive control, constraining the full robot to behave like these simplified models. This involves tracking preset reference paths for the Center of Mass and upper body obtained through low-dimensional models, often resulting in inefficient walking patterns with bent knees. However, we observe that bipedal balance is inherently low-dimensional and can be effectively described with simple state and action descriptors in a low-dimensional state space. This allows the robot's motion to evolve freely in its high-dimensional state space, only constraining its projection in the low-dimensional state space. In this work, we propose a novel control approach that avoids prescribing a low-dimensional model to the full model. Instead, our control framework uses a descriptive model with the minimum degrees of freedom necessary to maintain balance, allowing the remaining degrees of freedom to evolve freely in the high-dimensional space. This results in an efficient human-like walking gait and improved robustness.

Is hip tightness to blame for your back or knee pain? The cool tattoos are optional. Breakthroughs, discoveries, and DIY tips sent every weekday. Because, even among those of us who exercise regularly, the further we get from childhood the more limited our varieties of movement typically become, leading to weaker muscles, brittler bones and less mobile joints. "We don't move laterally as much anymore, as we get older and we're not playing sports. Even if you're long-distance running, you're just moving in one plane [of motion]," says Patrick Suarez, OCS, SCS, a physical therapist based in Albany, New York.

Flexibility is an essential part of staying fit. Breakthroughs, discoveries, and DIY tips sent every weekday. In your efforts to exercise, chances are you've worked on improving the four components of physical fitness. The problem is there are actually five . Criminally overlooked in the pursuit of big-ticket goals like strength, endurance, lung capacity and body composition is flexibility.
