When studying traumatic brain injury (TBI), are scientists capturing the motion that really matters?. To explore this question, researchers compared the motion delivered by a rotational injury device to the actual head movement recorded in a biological model using skull-mounted

Spinal implants often fail under stress, but new modeling techniques may help surgeons prevent that. A persistent challenge in spinal surgery is the unexpected failure of contoured spinal rods, which often break due to the stress induced during shaping. Researchers introduced a

Not all youth bike helmets are created equal, even when they meet the same safety standards. In a new study, researchers evaluated 21 youth bicycle helmets under oblique impacts to measure how well they reduced both linear and rotational head accelerations, two key contributors

Artificial intelligence could help improve how we analyze walking patterns in people with cerebral palsy (CP), no expensive lab equipment required. Seeking alternatives to force plate-based assessments, researchers trained a neural network to estimate ground reaction forces

Healing broken bones is still a major medical challenge, especially when strength and full functionality must be restored. Researchers penned a review examining the current landscape of scaffold-based tissue engineering for bone regeneration, with special attention to the role

A serious injury to aging tendons often means a slower, less complete recovery – one that science is still trying to fully understand. Researchers used a preclinical model of aging to investigate how two key proteins, decorin and biglycan, influence tendon healing. Using a

Robots may offer the solution to a frustrating problem in cancer care: how to place needles precisely during MRI scans without repeatedly moving the patient in and out of the machine. To solve it, engineers developed a compact, body-mounted robot that operates entirely within

For patients recovering from injury, illness, or surgery, getting the right muscles to fire can make all the difference. Researchers set out to improve the effectiveness of neuromuscular electrical stimulation (NMES) by mapping motor point (MP) locations across the hamstring

Blood clots in the brain can be deadly – but so can the treatments to prevent them. To treat intracranial aneurysms, clinicians often implant flow diverter stents (FDS), which reroute blood flow and encourage clotting within the aneurysm. These stents, however, can also cause

Predicting whether a brain aneurysm will rupture remains one of medicine’s most urgent and elusive challenges. A research team’s new prototype device offers a potential solution: it pulses fluid against the blood vessel wall and captures the resulting deformation using spectral

It’s hard to track how an abdominal aortic aneurysm is growing if the imaging isn’t clear or consistent. In a letter to the editor, researchers respond to a recent study on using 3D ultrasound to model aneurysm growth. They agree with the study’s approach, and highlight some key

Can clear aligners move teeth more effectively?. To explore this question, researchers developed an experimental method for assessing aligner performance by measuring strain in the bone – an approach that accounts for the role of the periodontal ligament, which is often

Osteoporosis silently weakens bones until a sudden fracture changes everything, and testing new treatments is too costly or risky to keep up. To overcome this hurdle, a team of researchers turned to virtual medicine. Using an advanced computational method called BoneStrength,

Collecting accurate data on how people move is difficult, yet it’s essential for designing better tools to support mobility, recovery, and aging. Researchers addressed this challenge by applying the James–Stein estimator, a statistical method that improves the accuracy of

When joint pain becomes debilitating, one major culprit is often the breakdown of cartilage, and rebuilding it remains one of medicine’s toughest challenges. To this end, researchers designed a layered scaffold that imitates how cartilage naturally works in the body. They used

Breathing shouldn’t be a battle, but for those with idiopathic pulmonary fibrosis (IPF), it often is. To improve the lives of patients living with this progressive, deadly lung disease, researchers explored a new way to deliver two leading IPF medications – Nintedanib (NTB) and

How does the ACL anchor itself to bone, and why does that matter when it tears?. Injury to the anterior cruciate ligament (ACL) can sideline athletes and impair everyday mobility, but repairing it effectively requires a deeper understanding of how the ligament connects to bone.

Dialysis access failure leads to more procedures, more hospital visits, and worse outcomes – making it crucial to understand what causes it. Researchers targeted a key cause of failure in arteriovenous grafts: neointimal hyperplasia (NIH), a type of tissue overgrowth linked to

Some knees wear down faster than others, even under the same stress. Understanding how different people’s knee joints respond to loading over time is essential for improving treatments for conditions like osteoarthritis. To this end, researchers introduced a workflow that blends

After chemotherapy, some breast cancers still return and spread, but we don’t yet know which patients are most at risk. To tackle this problem, researchers studied GRP78, a stress-response protein, to see if it could help predict which triple-negative breast cancer (TNBC) cells
