A Royal Society Open Science study analyzing T. rex footprints and leg anatomy finds the giant predator walked on its toes with birdlike, quick strides rather than heel-first stomping. Juveniles could reach over 37 ft/s and adults about 20 ft/s, suggesting different hunting behaviors as they aged and reinforcing the link between tyrannosaurs and living birds.
Sea stars crawl using hundreds of tube feet coordinated by local foot–surface interactions rather than a central brain. By adjusting how long each foot stays adhered, they modulate gait to meet mechanical demands, a finding supported by weight-adding experiments and inverted-walking tests that show the decentralized foot control at work. Researchers visualized foot contact with light-refraction imaging, revealing robust, decentralized strategies for navigating varied terrains.
A mathematician explores the theoretical physical limits of human height and foot size, concluding that while extremely tall humans like Robert Wadlow are possible in theory, biological and physical constraints such as blood pressure and the square-cube law likely prevent humans from evolving to much greater heights.
Cycling is at least four times more energy-efficient than walking due to biomechanical advantages, lower impact, and the ability to optimize muscle effort with gears, making it a highly effective and sustainable form of exercise and transportation.
Scientists captured high-speed footage of venomous snakes from different families biting prey to study their attack mechanisms, revealing significant differences in how they deliver venom and hunt, which enhances understanding of snake evolution and behavior.
Scientists used high-speed cameras to capture in unprecedented detail how venomous snakes strike their prey, revealing that most vipers bite within 0.1 seconds, and different snake families employ various attack strategies, enhancing understanding of snake predation mechanics.
Researchers concluded that the famous 'Chicago Rat Hole' was not made by a rat, but most likely by a squirrel, based on size and shape analysis of the imprint, ending a viral mystery in Roscoe Village.
Scientists discovered that cancer cells rapidly boost their energy production through mitochondria when physically squeezed, aiding in DNA repair and survival under stress, revealing a potential target for preventing cancer spread.
Scientists study the complex and flexible movements of octopus arms in the wild to inspire the design of advanced robotic arms capable of delicate and precise tasks, highlighting the octopus's remarkable intelligence and adaptability as models for technological innovation.
A study using 3D reconstructions reveals that the tail of the sauropod Giraffatitan was more mobile and complex than previously thought, providing new insights into its posture, movement, and social behavior.
Coco Gauff has replaced her coach with a biomechanics specialist ahead of the US Open to improve her serve and overall performance, following recent struggles and a dip in form.
Coco Gauff has made a significant coaching change ahead of the US Open, parting ways with her previous coach and hiring biomechanics expert Gavin MacMillan to improve her game, especially her serve, as she prepares for the singles draw starting Sunday.
A study by Binghamton University researchers explains that skin wrinkles with age due to repeated stretching and buckling, similar to denim creases, with changes in skin stiffness and collagen density contributing to this process. The findings provide experimental evidence of the physical mechanisms behind aging skin and have implications for skincare and understanding other tissues, as well as the impact of sun exposure on skin aging.
Scientists used high-speed cameras and micro-CT scans to study how the squirting cucumber precisely aims and explodes to disperse seeds, revealing its sophisticated natural launch system that could inspire future soft robotics and medical devices.
A recent study reveals that human sperm can defy Newton's third law of motion by utilizing non-reciprocal internal forces powered by 'odd elasticity,' enabling efficient movement through viscous environments and challenging traditional physics principles, with implications for biomedical engineering and fertility research.
