The brain's immune system has long been thought to exist independently from the rest of the body, complete with its own specialized immune cells and a blood-brain barrier that limits what can travel into the brain. https://medicalxpress.com/news/2026-08-discovery-reveals-aging-human-brains.html Thu, 06 Aug 2026 13:00:06 EDT news705238022 Seoul National University (SNU) College of Engineering announced that a research team led by Nathaniel S. Hwang, a professor in the Department of Chemical and Biological Engineering, has developed a bioceramic fracture fixation material that promotes bone regeneration by precisely controlling the timing of magnesium ion (Mg²⁺) release to suppress inflammatory immune responses during osteoporotic fracture healing. https://medicalxpress.com/news/2026-07-bioceramic-coated-implant-osteoporotic-fracture.html Wed, 29 Jul 2026 16:00:02 EDT news704554681 If there's a word that captures both the great promise and the persistent uncertainty of longevity medicine, it's peptides. https://medicalxpress.com/news/2026-07-longevity-medicine-peptide-crazy.html Tue, 28 Jul 2026 09:40:03 EDT news704446202 A newly filed patent from researchers at Ohio University could help develop more effective treatments for disorders related to growth hormone, thanks to a discovery that reveals exactly how a groundbreaking drug works at the molecular level. https://medicalxpress.com/news/2026-07-patent-pave-effective-growth-hormone.html Mon, 27 Jul 2026 23:00:01 EDT news704365807 The brain continuously produces metabolic waste that must be removed to maintain healthy function. Cerebrospinal fluid (CSF) plays a central role in this process by carrying away proteins such as amyloid-β, phosphorylated tau and α-synuclein, which are linked to Alzheimer's disease, Parkinson's disease and other neurodegenerative disorders when they accumulate abnormally. https://medicalxpress.com/news/2026-07-scientists-hidden-gateways-brain.html Wed, 22 Jul 2026 11:40:01 EDT news703938817 For decades, medicine has chased a simple but elusive goal of delivering the right drug to the right place at the right time. New research from the University of Oregon suggests that when it comes to healing from injury, the timing of regenerative cues might be even more important than previously realized. https://medicalxpress.com/news/2026-07-injuries-regenerative-cues.html Sun, 19 Jul 2026 10:00:04 EDT news703497877 Temporomandibular disorders (TMDs) are a group of more than 30 conditions that cause pain and dysfunction in the jaw. So what could a small tissue sample from a rat's knee have to do with treating them? https://medicalxpress.com/news/2026-07-advanced-imaging-uncovers-3d-nerve.html Tue, 07 Jul 2026 16:00:06 EDT news702654928 T cells are an elite fighting force of the immune system, seeking out and destroying diseased cells. But in a prolonged campaign against a chronic condition—like a viral infection or cancer—the body needs a steady supply of these killer troops. Where and how these killer troops are generated has been a mystery. https://medicalxpress.com/news/2026-07-rare-stem-cells-key-chronic.html Wed, 01 Jul 2026 14:20:03 EDT news702128161 A new form of CAR T-cell therapy has been designed to find and destroy the cancer-driving stem cells responsible for a group of blood cancers known as myeloproliferative neoplasms (MPNs), while leaving healthy blood cells unharmed, according to new research led by UCL and University of Oxford researchers. https://medicalxpress.com/news/2026-07-car-cell-therapy-key-mutation.html Wed, 01 Jul 2026 14:00:03 EDT news702115621 Orthopedic implants are designed to restore movement and relieve pain, offering patients a second or even third chance at mobility. A hip or knee replacement is often framed as a durable fix, engineered to last for years, sometimes decades, inside the human body. And modern hip and knee implants exceed expectations, providing long service time and significantly improved quality of life for the vast majority of patients. But durability inside biology, especially the human body, is never static once a foreign material is introduced. It responds continuously, at every scale. https://medicalxpress.com/news/2026-06-joints-corrosion-reshape-hip-knee.html Mon, 15 Jun 2026 17:10:03 EDT news700759501 For patients suffering from traumatic injuries that leave behind "volumetric" gaps—where significant bone and blood vessels are lost—the clock is always ticking. Without a nearby blood supply, cells in the center of a large injury cannot survive, often leading to permanent tissue loss or failed grafts. https://medicalxpress.com/news/2026-06-natural-protein-scaffold-bone-blood.html Thu, 11 Jun 2026 16:40:04 EDT news700413241 Dental implants have given tens of millions of people something dentures never could: a full set of fixed and fully functioning teeth. Unfortunately, 10% to 20% of implant patients eventually experience an aggressive jawbone infection called peri-implantitis. Antibiotics usually fail to stop the infection for reasons that researchers have not understood until now. https://medicalxpress.com/news/2026-05-titanium-particles-antibiotics-dental-implant.html Thu, 28 May 2026 16:00:06 EDT news699199321 A largely overlooked space between cells in women's brains may hold the key to understanding memory loss tied to estrogen decline after menopause, reports a new preclinical Northwestern Medicine study. https://medicalxpress.com/news/2026-05-memory-decline-menopause-linked-loss.html Tue, 26 May 2026 05:30:01 EDT news698919841 Scientists at Houston Methodist have developed an artificial intelligence platform that can decode how cells communicate inside the human body, opening a window into conditions such as Alzheimer's disease, cancer, and potentially accelerating the search for new treatments. https://medicalxpress.com/news/2026-05-ai-platform-decodes-cells-cancer.html Thu, 14 May 2026 16:20:03 EDT news697992975 For highly aggressive types of blood cancer, stem cell transplantation is often the only potentially curative therapy, yet even after a transplant, these cancers often return. Now a clinical trial, led by researchers at Washington University School of Medicine in St. Louis, shows that a stem cell transplant in which the donor cells have been genetically engineered to remove a particular protein helps prevent toxic side effects and potentially improves the effectiveness of therapies given after a transplant to help prevent cancer recurrence. https://medicalxpress.com/news/2026-05-gene-stem-cell-transplant-aggressive.html Tue, 12 May 2026 05:00:08 EDT news697735621 Smart implants that not only stabilize a fracture but also monitor the healing process from day one—and deliver targeted support when required—are currently being developed at Saarland University by a team of engineers, medical researchers and computer scientists. The engineering team led by Professor Paul Motzki is contributing shape-memory micro-actuators with integrated sensing capabilities, while Professor Bergita Ganse and her research group provide the medical expertise in fracture healing. If a fracture is not healing as it should, these novel implants can respond mechanically at the fracture gap by adapting their stiffness or by applying controlled micro-movements to mechanically stimulate tissue and promote bone regeneration. https://medicalxpress.com/news/2026-04-smart-implants-robotic-micro-actuators.html Tue, 21 Apr 2026 21:40:03 EDT news695992511 A research team has discovered a new mechanism and drug combination strategy that can effectively treat osteoporosis, a representative disease of super-aging societies. The research findings were published on April 2 in Bone Research. The researchers were led by Seoul National University College of Engineering's Prof. Sunghoon Kwon and Prof. Sang Wan Kim. https://medicalxpress.com/news/2026-04-laser-breakthrough-supercharges-osteoporosis-treatment.html Tue, 14 Apr 2026 14:40:04 EDT news695394053 A doctor orders an X-ray for a patient with a knee ache. The bones look fine, and the most likely prognosis is arthritis, which occurs when the soft tissue between joints breaks down. But X-rays are much better with hard tissues like bone, which absorb X-rays and turn white in an image, while soft tissue allows most of the X-rays to pass through. https://medicalxpress.com/news/2026-04-ray-soft-tissue-contrast-agent.html Tue, 07 Apr 2026 11:30:02 EDT news694779661 Periodontitis is a serious chronic inflammatory form of gum disease that affects millions worldwide. It can lead to tooth loss and the destruction of supporting bone. This disease has also been linked to other health problems, including diabetes, respiratory infections, and heart disease, impacting quality of life and increasing health care costs. https://medicalxpress.com/news/2026-04-stiff-defense-physical-rigidity-healthy.html Wed, 01 Apr 2026 18:40:01 EDT news694258168 A research team from the Department of Orthopedics and Traumatology, School of Clinical Medicine, LKS Faculty of Medicine at the University of Hong Kong (HKUMed), has developed a titanium implant surface that can be activated by near-infrared (NIR). With just 15 minutes of NIR irradiation, this surface can eliminate 99.94% of Staphylococcus aureus (S. aureus) biofilms without the use of antibiotics, while simultaneously promoting bone-implant fusion. https://medicalxpress.com/news/2026-04-smart-titanium-implant-enables-rapid.html Wed, 01 Apr 2026 13:00:01 EDT news694264081 A bone-like composite developed at EPFL uses naturally occurring enzymes to accelerate mineralization through an energy-efficient, room-temperature process. The strong, lightweight material shows promise for bone repair applications. https://medicalxpress.com/news/2026-03-3d-printable-scaffold-fast-bone.html Wed, 11 Mar 2026 09:20:03 EDT news692436152 Lasers cut precisely and without contact—ideal for surgery. The problem is that in hard tissues such as bone, they are too slow and do not cut deep enough. Researchers at the University of Basel have now demonstrated a way to cut much deeper and faster with a surgical laser than with previous laser systems. https://medicalxpress.com/news/2026-02-laser-surgery-bone-deeper.html Sun, 01 Mar 2026 11:00:05 EST news691381480 With the aim of restoring female hormone cycles for pediatric cancer survivors, a team of University of Michigan researchers has demonstrated that donated ovarian tissue, hidden from the immune system in a capsule, can produce natural hormone cycles in mice. The study is published in the journal Science Advances. https://medicalxpress.com/news/2026-02-encapsulated-ovarian-donor-tissue-natural.html Wed, 18 Feb 2026 17:18:33 EST news690657482 A research lab at the University of Caen Normandy (France) has succeeded in making cartilage using decellularized apples. https://medicalxpress.com/news/2026-02-lab-grown-human-cartilage-apples.html Wed, 18 Feb 2026 12:04:49 EST news690638642 Researchers at Pompeu Fabra University (UPF) have made a great leap toward predicting the risk of hip fracture among people with osteoporosis and evaluating the effectiveness of specific drugs to prevent it. The BCN Med Tech Unit of the UPF Department of Engineering, together with the company 3D-Shaper Medical, have developed two leading studies in which they present a new computational system to predict and prevent the risk of hip fracture far more precisely than the most common clinical methods today. https://medicalxpress.com/news/2026-02-hip-fracture-osteoporosis.html Tue, 17 Feb 2026 16:26:45 EST news690567962 A study led by Dartmouth Engineering professors demonstrates a possible new technique for connecting electronic implants with the surface of the brain, as well as a new method for ensuring safe, long-term medical access to the brain. Alexander Boys and Katie Hixon combined their research areas of thin-film bioelectronics and regenerative tissue engineering to produce a neural device that promotes healing of the skull following implantation onto the brain. Their study is published in Advanced Materials Technologies and will be featured on the journal's cover in March. https://medicalxpress.com/news/2026-02-neural-implant-approach-regrows-skull.html Thu, 05 Feb 2026 09:40:01 EST news689504494 Bone and skeletal injuries cause extensive and long-term functional impairments worldwide. In a new study, researchers at Lund University in Sweden show how a cell-free cartilage structure can safely guide bone repair without triggering strong immune responses. The transplant has been successfully tested in animal models, and the next step is to evaluate the tissue engineering approach in humans. The study is published in the journal Proceedings of the National Academy of Sciences. https://medicalxpress.com/news/2026-01-universal-tissue-approach-future-bone.html Wed, 28 Jan 2026 17:09:43 EST news688842541 In a basic science study last year, researchers discovered that taurine, available in energy drinks and as a supplement, feeds the growth of leukemia stem cells. A new study recently published by the same Wilmot Cancer Institute team expands that work and suggests that as taurine fuels leukemia, it becomes less available for other normal cells and may result in weaker bones in mice. https://medicalxpress.com/news/2026-01-taurine-fuels-leukemia-impact-bone.html Mon, 26 Jan 2026 12:45:56 EST news688653863 A "gene silencer" (technically known as small interfering RNA, or siRNA), locally delivered by nanoparticles embedded in an injectable gel produced through 3D printing, can switch off the defective gene responsible for serious rare diseases known as craniosynostoses. These conditions are characterized by malformations of the skull and are currently treatable only through highly invasive surgical procedures performed in newborns and often repeated throughout childhood. https://medicalxpress.com/news/2026-01-rare-cranial-disorders-invasive-therapy.html Fri, 23 Jan 2026 13:26:43 EST news688397161 When a house catches on fire, we assume that a smoke alarm inside will serve one purpose and one purpose only: warn the occupants of danger. But imagine if the device could transform into something that could fight the fire as well. https://medicalxpress.com/news/2026-01-nerve-circuitry-bone-physicians-key.html Thu, 08 Jan 2026 16:53:33 EST news687113581
