Many liver and lung cancers arise in tissue that's already been scarred by chronic disease, such as hepatitis, cirrhosis or long-term lung damage. That scarring creates an environment that suppresses nearby immune cells, so by the time a tumor takes hold, it's often already shielded from the immune system and immunotherapy. https://phys.org/news/2026-09-nanoparticles-tumor-scarring-enable-immunotherapy.html Bio & Medicine Fri, 25 Sep 2026 12:00:20 EDT news709548841 Human and chimpanzee genomes are more than 98% identical, and the genes themselves barely differ. The changes that make us human are thought to hide instead in the DNA that controls when and where genes switch on. https://phys.org/news/2026-09-evolution-human-skeleton-clues-cartilage.html Evolution Wed, 23 Sep 2026 11:00:18 EDT news709377181 As we age, some of the cells in our body enter a state of senescence, in which they stop dividing but do not die. Those senescent cells can contribute to age-related disorders such as cancer, tissue degeneration and inflammatory diseases. In an advance that could lead to better ways to diagnose and treat those diseases, MIT researchers have developed a noninvasive way to detect biomarkers of senescence. Their method is based on Raman microscopy, which can reveal the biochemical composition of cells without harming them. https://phys.org/news/2026-09-ai-powered-barcode-unmasks-zombie.html Cell & Microbiology Mon, 21 Sep 2026 05:00:07 EDT news708944642 As dogs age, many develop more than one chronic health condition. New research from Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) shows those conditions can dramatically shorten a dog's lifespan, highlighting the importance of managing multiple diseases together rather than individually. https://phys.org/news/2026-08-chronic-conditions-key-longer-lifespan.html Veterinary medicine Mon, 31 Aug 2026 17:50:01 EDT news707414941 New research by an interdisciplinary team in Lithuania has revealed a promising and unconventional approach to cartilage regeneration. Using extracellular vesicles derived from menstrual blood stromal cells, the researchers demonstrated their potential to stimulate cartilage repair—paving the way for a future cell-free therapy for osteoarthritis. https://phys.org/news/2026-04-menstrual-blood-derived-particles-osteoarthritis.html Bio & Medicine Fri, 10 Apr 2026 11:40:03 EDT news695034481 Osteoarthritis is a highly prevalent joint disease that leads to cartilage breakdown, pain and disability, yet there are still no FDA-approved treatments that can slow or reverse its progression. RNA-based therapies hold great promise because they can silence the molecular signals that drive cartilage degeneration. However, for these treatments to work, they must reach the damaged regions, called lesions, within the cartilage. https://phys.org/news/2026-01-smart-nanoparticles-gene-therapy-osteoarthritis.html Bio & Medicine Wed, 14 Jan 2026 09:30:01 EST news687604937 Boise State University researchers have developed a new technique and platform to communicate with cells and help drive them toward cartilage formation.

A new study found that wolves select adult moose based on age and osteoarthritis, a chronic disease that can be influenced by genetics. Wolves also showed a strong preference for elderly moose over prime-aged adults. The results indicate that wolves play an important role in keeping prey populations healthy and have considerable implications for the conservation management of predator and prey populations. https://phys.org/news/2022-04-moose-populations-healthy-wolves.html Plants & Animals Wed, 20 Apr 2022 03:13:54 EDT news569643225 A textile-based implant containing cartilage derived from stem cells reduced pain and restored hip joint function to baseline levels in a study of dogs with symptoms of moderate osteoarthritis. The study, led by researchers at North Carolina State University, Washington University in St. Louis and Cytex Therapeutics Inc., could be a significant first step toward preventative, less invasive joint resurfacing in dogs and humans. https://phys.org/news/2021-09-cartilage-resurfacing-implant-pain-hip.html Plants & Animals Wed, 15 Sep 2021 15:23:32 EDT news550938208 In an aging population, the social impact of osteoarthritis (OA) can dramatically increase to become the most common musculoskeletal disease. However, at present, therapies are limited to palliative treatments or surgical intervention alone, since disease-modifying OA (DMOA) drugs are scarce, primarily due to the absence of relevant preclinical models of the disease. As a result, tissue engineers and materials scientists aim to develop in vitro models for reliably predicting the efficacy of the requisite DMOA drugs. https://phys.org/news/2019-06-osteoarthritic-oa-phenotype-cartilage-on-a-chip-coc.html Biotechnology Mon, 17 Jun 2019 09:30:01 EDT news479976329 Original concerns that cloning caused early-onset osteoarthritis (OA) in Dolly the sheep are unfounded, say experts at the University of Nottingham and the University of Glasgow. https://phys.org/news/2017-11-radiographs-dolly-skeleton-abnormal-osteoarthritis.html Biotechnology Thu, 23 Nov 2017 09:41:01 EST news430652425 Osteoarthritis is a debilitating condition that affects at least 27 million people in the United States, and at least 12 percent of osteoarthritis cases stem from earlier injuries. Over-the-counter painkillers, such as anti-inflammatory drugs, help reduce pain but do not stop unrelenting cartilage destruction. Consequently, pain related to the condition only gets worse. https://phys.org/news/2016-09-nanoparticle-future-osteoarthritis-treatment.html Bio & Medicine Mon, 26 Sep 2016 14:50:01 EDT news394112185 Three weeks after the scientific world marked the 20th anniversary of the birth of Dolly the sheep new research, published by The University of Nottingham, in the academic journal Nature Communications has shown that four clones derived from the same cell line—genomic copies of Dolly—reached their 8th birthdays in good health.
