Boosting this pathway in people reduced inflammation-related immune changes and sped up pain relief, pointing toward potential new treatments for chronic inflammatory diseases. Sat, 12 Sep 2026 21:44:05 EDT https://www.sciencedaily.com/releases/2026/09/260911214306.htm https://www.sciencedaily.com/releases/2026/09/260911214254.htm A 10-year study of more than 6,000 adults found that popular coronary calcium scans may add little to standard heart disease risk estimates for many people. But for patients with borderline or intermediate risk, the scans could make a meaningful difference by revealing who is actually more likely to develop heart disease.

Researchers found that certain neutrophils release Il-4, which calms harmful inflammation and allows injured nerve fibers to grow again. Without these cells, healing stalled, but adding Il-4 restored regeneration. Scientists now want to know whether the same mechanism could someday be harnessed to improve spinal cord repair in humans. Mon, 07 Sep 2026 20:31:34 EDT https://www.sciencedaily.com/releases/2026/09/260906170136.htm https://www.sciencedaily.com/releases/2026/09/260901070550.htm Following nearly 10,000 older women for 10 years, researchers found that tea drinking was associated with slightly higher hip bone density. Moderate coffee consumption did not appear harmful, but drinking more than five cups a day was linked to lower bone density. The findings suggest tea may offer a small bone-health boost, while excessive coffee could carry some drawbacks. Wed, 02 Sep 2026 02:04:39 EDT https://www.sciencedaily.com/releases/2026/09/260901070550.htm https://www.sciencedaily.com/releases/2026/09/260901070538.htm Scientists have found evidence that vulnerability to rheumatoid arthritis may begin before birth. Finger joints commonly affected by the disease develop with different tissue structures and larger populations of specialized fibroblasts than joints that are usually spared. Those cells also respond differently to inflammation, suggesting that the architecture of each joint may help determine where arthritis eventually takes hold. Sat, 05 Sep 2026 18:19:53 EDT https://www.sciencedaily.com/releases/2026/09/260901070538.htm https://www.sciencedaily.com/releases/2026/08/260828082330.htm CAR T-cell therapy dramatically reduced disease activity in six people with severe rheumatoid arthritis that had resisted other treatments, with three achieving medication-free remission. The treatment may work by clearing out harmful immune cells and effectively rebooting part of the immune system, although much larger studies are still needed. Sat, 29 Aug 2026 21:28:13 EDT https://www.sciencedaily.com/releases/2026/08/260828082330.htm https://www.sciencedaily.com/releases/2026/08/260828005427.htm Scientists have identified a protein that acts like a brake on the nervous system’s ability to repair damaged connections. Blocking AHR helped injured nerve fibers regrow and improved movement and sensation in mice with nerve or spinal cord injuries. The discovery could eventually point toward new treatments designed to shift neurons from simply surviving an injury to actively rebuilding themselves.

Even more intriguingly, two of the most promising compounds worked when administered as eye drops, pointing toward a potentially simple new approach to restoring vision. Fri, 28 Aug 2026 10:21:46 EDT https://www.sciencedaily.com/releases/2026/08/260828005224.htm https://www.sciencedaily.com/releases/2026/08/260826055442.htm Researchers discovered a brain-based “brake” that can shut down chronic nerve pain in mice by calming an overactive pain circuit. Targeting this system more precisely could one day lead to powerful pain relief without affecting opioid receptors throughout the entire body. Thu, 27 Aug 2026 00:46:20 EDT https://www.sciencedaily.com/releases/2026/08/260826055442.htm https://www.sciencedaily.com/releases/2026/08/260820202904.htm Scientists have linked a specific gut bacterium, Roseburia inulinivorans, to stronger muscles in both humans and mice. Older adults who carried it had 29% greater handgrip strength, while treated mice gained about 30% more grip strength and developed larger, more fast-twitch muscle fibers. The bacterium was also less common in older people. Researchers say it could eventually become a probiotic candidate for helping combat age-related muscle loss. Fri, 21 Aug 2026 22:27:20 EDT https://www.sciencedaily.com/releases/2026/08/260820202904.htm https://www.sciencedaily.com/releases/2026/08/260815064825.htm A low-fat vegan diet may help people lose weight without counting calories, shrinking portions, or feeling constantly hungry. In a 16-week clinical trial, people eating mostly fruits, vegetables, grains, and legumes consumed about 357 fewer calories per day even though the total amount of food they ate barely changed. Mon, 17 Aug 2026 09:07:03 EDT https://www.sciencedaily.com/releases/2026/08/260815064825.htm https://www.sciencedaily.com/releases/2026/08/260808234959.htm Just a couple of hours of strength training each week could have surprisingly powerful effects on longevity. People who lifted weights for around 90 to 120 minutes weekly had a 13% lower risk of dying early, with especially large reductions in deaths from cardiovascular and neurological diseases. Pairing strength training with regular aerobic exercise was even more impressive, lowering overall death risk by about 45%. Sun, 09 Aug 2026 20:52:37 EDT https://www.sciencedaily.com/releases/2026/08/260808234959.htm https://www.sciencedaily.com/releases/2026/08/260807235243.htm An intensive seven-day meditation retreat triggered striking changes across the brain and body, including shifts tied to neuroplasticity, immunity, metabolism, and natural pain relief. Participants also showed brain connectivity patterns resembling those associated with psychedelic experiences, suggesting that powerful altered states may be achievable without drugs. Sat, 08 Aug 2026 23:50:35 EDT https://www.sciencedaily.com/releases/2026/08/260807235243.htm https://www.sciencedaily.com/releases/2026/08/260806051943.htm Genetic changes may set off a chain reaction that causes the spine’s natural shock absorbers to harden and deteriorate. Zebrafish with a faulty collagen-related gene developed mineral buildup and spinal fusion similar to human disc disease. Researchers were able to reduce the damage using an existing osteoporosis drug and by targeting fat metabolism. The discovery points to several exciting possibilities for future back pain treatments. Thu, 06 Aug 2026 05:50:21 EDT https://www.sciencedaily.com/releases/2026/08/260806051943.htm https://www.sciencedaily.com/releases/2026/08/260805082452.htm Tiny pollution particles from smoke, soot, and dust may worsen rheumatoid arthritis and raise the risk of painful flares, particularly after prolonged exposure. The findings suggest that avoiding poor air quality could become an important part of managing the disease. Wed, 05 Aug 2026 23:32:50 EDT https://www.sciencedaily.com/releases/2026/08/260805082452.htm https://www.sciencedaily.com/releases/2026/07/260724061448.htm A prebiotic fiber supplement reduced knee osteoarthritis pain while also improving grip strength and pain sensitivity in a six-week trial. The results hint at a fascinating gut-muscle-pain connection and suggest that a simple daily supplement may be easier to maintain than digital physiotherapy. Sat, 25 Jul 2026 06:01:05 EDT https://www.sciencedaily.com/releases/2026/07/260724061448.htm https://www.sciencedaily.com/releases/2026/07/260723084043.htm A major review found that exercise produces only small average improvements in hip osteoarthritis pain and physical function. It may still help some people, but researchers warn that current evidence is too limited to know which exercises work best. Mon, 27 Jul 2026 22:09:34 EDT https://www.sciencedaily.com/releases/2026/07/260723084043.htm https://www.sciencedaily.com/releases/2026/07/260721000845.htm A plant-derived compound reduced swelling, inflammation, and joint damage in rats with rheumatoid arthritis. It also helped rebalance immune activity and improve the way certain fats were processed in the body. Researchers say the findings could lead to a new approach for treating the disease. Wed, 22 Jul 2026 21:57:05 EDT https://www.sciencedaily.com/releases/2026/07/260721000845.htm https://www.sciencedaily.com/releases/2026/07/260710003521.htm A simple, non-invasive ultrasound treatment could one day help injured joints heal instead of remaining trapped in a cycle of damaging inflammation. Researchers at The University of Alabama in Huntsville found that continuous low-intensity ultrasound encouraged key immune cells called macrophages to shift from an inflammatory state toward one that supports tissue repair. Sun, 12 Jul 2026 06:07:21 EDT https://www.sciencedaily.com/releases/2026/07/260710003521.htm https://www.sciencedaily.com/releases/2026/07/260709160641.htm Many of the body's biggest flaws are the result of evolution building on old designs instead of starting over. Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that worked well enough for survival but still leave us prone to pain, injury, and disease. Structures like the appendix and ear muscles also remain because they were never harmful enough for evolution to eliminate. Together, these features tell the story of a body shaped by history rather than perfection.

Researchers also found signs of brain damage associated with early dementia, suggesting the effects can linger long after alcohol use has stopped. Fri, 03 Jul 2026 19:43:50 EDT https://www.sciencedaily.com/releases/2026/06/260626030437.htm https://www.sciencedaily.com/releases/2026/06/260624025511.htm Osteopenia is a common but often overlooked condition that causes bones to become less dense and more fragile. Because it develops silently, many people only discover they have it after a fracture or bone scan. Aging, menopause, poor diet, and inactivity can all contribute to bone loss. Fortunately, exercise, adequate calcium and vitamin D, and other healthy habits can slow or even partially reverse the decline. Thu, 25 Jun 2026 00:25:26 EDT https://www.sciencedaily.com/releases/2026/06/260624025511.htm https://www.sciencedaily.com/releases/2026/06/260619033343.htm Compounds responsible for the aroma of cannabis and many other plants may offer a surprising new way to relieve chronic pain. Researchers found that several cannabis-derived terpenes significantly reduced pain in mouse models of fibromyalgia and post-surgical pain, with one terpene, geraniol, showing especially strong effects. Unlike THC, these compounds are not associated with psychoactive effects, making them a potentially attractive alternative for pain treatment. Sat, 20 Jun 2026 11:33:51 EDT https://www.sciencedaily.com/releases/2026/06/260619033343.htm https://www.sciencedaily.com/releases/2026/06/260617032207.htm Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all—it may simply be switched off. Using a two-stage treatment, researchers redirected the body’s normal healing response away from scar formation and toward regrowth, successfully restoring bone, joints, ligaments, and tendons after amputation in animal studies. Wed, 17 Jun 2026 10:25:31 EDT https://www.sciencedaily.com/releases/2026/06/260617032207.htm https://www.sciencedaily.com/releases/2026/06/260616102217.htm A minimally invasive treatment that blocks inflammation-driving blood vessels in the knee provided significant pain relief and improved function for osteoarthritis patients, with benefits lasting at least a year. The procedure was safe, highly successful, and could offer a new alternative for people seeking relief before considering knee replacement. Wed, 17 Jun 2026 00:46:51 EDT https://www.sciencedaily.com/releases/2026/06/260616102217.htm https://www.sciencedaily.com/releases/2026/06/260615033837.htm A large real-world study suggests semaglutide (Ozempic, Wegovy, Rybelsus) may offer an unexpected bonus for people with type 2 diabetes: stronger protection against bone fractures while delivering greater weight loss. Researchers analyzing health records from nearly 60,000 adults found that people taking semaglutide experienced about 15% fewer fractures than those using other common weight-loss medications, despite losing more weight. Tue, 16 Jun 2026 08:07:39 EDT https://www.sciencedaily.com/releases/2026/06/260615033837.htm https://www.sciencedaily.com/releases/2026/06/260614011852.htm For years, calcium and vitamin D supplements have been promoted as a simple way for older adults to protect their bones and prevent falls. But a massive review of nearly 154,000 people found that calcium, vitamin D, or a combination of both provided little to no meaningful protection against fractures or falls for most older adults. Mon, 15 Jun 2026 08:44:53 EDT https://www.sciencedaily.com/releases/2026/06/260614011852.htm https://www.sciencedaily.com/releases/2026/06/260612021604.htm A new treatment that blocks an aging-related protein restored lost cartilage in old mice and helped prevent arthritis after knee injuries. Human cartilage samples showed similar signs of regeneration, raising hopes for a future drug that could repair joints instead of replacing them. Fri, 12 Jun 2026 08:35:15 EDT https://www.sciencedaily.com/releases/2026/06/260612021604.htm https://www.sciencedaily.com/releases/2026/06/260611024609.htm Just 90–120 minutes of strength training a week may deliver some of the biggest long-term health rewards, according to a study tracking more than 147,000 people for 30 years. That amount was linked to lower risks of death overall, particularly from cardiovascular and neurological diseases. Combining strength workouts with aerobic exercise produced even stronger benefits. Fri, 12 Jun 2026 00:46:24 EDT https://www.sciencedaily.com/releases/2026/06/260611024609.htm https://www.sciencedaily.com/releases/2026/06/260608040023.htm The largest review ever conducted on opioids for acute pain found that these widely prescribed drugs often deliver only small, short-lived benefits. For many common conditions, including some surgeries and kidney stone pain, opioids performed no better than a placebo. Researchers also found higher rates of side effects and warned that dependence can begin after only a short period of use. Tue, 09 Jun 2026 02:44:51 EDT https://www.sciencedaily.com/releases/2026/06/260608040023.htm https://www.sciencedaily.com/releases/2026/05/260530053426.htm A promising new study suggests rheumatoid arthritis may not be as inevitable as once thought for people at high risk. Researchers found that just one year of treatment with the immune-targeting drug abatacept delayed the onset of rheumatoid arthritis by up to four years, with benefits lasting long after treatment ended. Mon, 01 Jun 2026 09:25:47 EDT https://www.sciencedaily.com/releases/2026/05/260530053426.htm https://www.sciencedaily.com/releases/2026/05/260528082459.htm Cambridge researchers created miniature brain-and-spinal-cord systems in the lab that can send signals and even trigger tiny muscle contractions. They discovered that human neurons gradually lose their ability to regrow after damage during development — but that ability can potentially be switched back on. The team identified a gene network controlling this process and found that an existing hormone drug dramatically boosted nerve fiber regrowth. Thu, 28 May 2026 22:55:05 EDT https://www.sciencedaily.com/releases/2026/05/260528082459.htm https://www.sciencedaily.com/releases/2026/05/260523103950.htm For millions battling chronic nerve pain, even the softest touch can feel agonizing — but scientists may have uncovered a radically new way to stop it at the source. Researchers at Duke University found that damaged nerves can be revived by supplying them with healthy mitochondria, the tiny energy producers inside cells. Sun, 24 May 2026 07:51:53 EDT https://www.sciencedaily.com/releases/2026/05/260523103950.htm https://www.sciencedaily.com/releases/2026/05/260521072408.htm Researchers have discovered that the GLP-1 hormone targeted by drugs like Wegovy is present in very low amounts inside the joints of arthritis patients. That finding suggests high-dose GLP-1 medications could potentially reach the joints and influence inflammation directly, not just help through weight loss. Scientists say this could open the door to a completely new approach to arthritis treatment. Fri, 22 May 2026 02:12:43 EDT https://www.sciencedaily.com/releases/2026/05/260521072408.htm https://www.sciencedaily.com/releases/2026/05/260519224308.htm Low vitamin D levels could be quietly making breast cancer surgery recovery far more painful. In a new study, patients deficient in vitamin D were three times more likely to experience moderate to severe pain after mastectomy surgery and ended up using significantly more opioid medication to cope. Researchers say vitamin D may help regulate how the body processes pain through its effects on inflammation and the immune system.

A major study of more than 5,000 women found that simple signs of muscle strength, like a firm hand grip or the ability to quickly stand up from a chair, were strongly linked to lower risk of death over the next eight years. Mon, 11 May 2026 21:13:48 EDT https://www.sciencedaily.com/releases/2026/05/260510234722.htm https://www.sciencedaily.com/releases/2026/05/260506225235.htm Aging doesn’t just add fat—it redistributes it in risky ways, pushing more into the abdomen where it can harm health. Scientists found that testosterone plays a key role in this shift. In older women recovering from hip fractures, a testosterone gel combined with exercise helped prevent the usual rise in dangerous visceral fat. The result could point to a powerful new strategy for improving recovery and long-term health. Thu, 07 May 2026 05:25:59 EDT https://www.sciencedaily.com/releases/2026/05/260506225235.htm https://www.sciencedaily.com/releases/2026/04/260426012317.htm Deep within the brain, scientists have uncovered a hidden “switch” that may decide whether pain fades away—or lingers for months or even years. Researchers found that a small, little-known region called the caudal granular insular cortex (CGIC) acts like a command center, telling the body to keep pain signals alive long after an injury has healed. In animal studies, shutting down this pathway not only prevented chronic pain from forming but could even erase it once it had taken hold.

Studies in both mice and thousands of children found links to symptoms like pain, constipation, and IBS. Scientists discovered that different biological pathways control different gut issues, hinting at more personalized treatments in the future. The research also highlights how a child’s early environment can have lasting physical effects—not just emotional ones.

Despite affecting nearly 600 million people worldwide — and potentially a billion by 2050 — the most powerful treatment isn’t surgery or medication. It’s exercise. Movement nourishes cartilage, strengthens muscles, reduces inflammation, and even reshapes the biological processes driving joint damage. Wed, 04 Mar 2026 16:35:02 EST https://www.sciencedaily.com/releases/2026/03/260303145725.htm https://www.sciencedaily.com/releases/2026/03/260303050626.htm When a bone break is too severe to heal on its own, surgeons often rely on grafts or rigid metal implants — but both come with serious drawbacks. Now, researchers at ETH Zurich have created a jelly-like hydrogel that mimics the body’s natural healing process, offering a potentially game-changing alternative. Made of 97% water, this soft material can be laser-printed into intricate bone-like structures at record-breaking speeds, down to details thinner than a human hair.

After reviewing dozens of clinical trials involving more than 13,000 participants, researchers found that benefits for knee osteoarthritis pain were minimal and tended to shrink in larger or longer-term studies.

By using advanced chemical screening on umbilical cord blood, scientists detected 42 different PFAS compounds, including many that standard tests do not routinely check for. These long lasting chemicals are found in common products like nonstick cookware, food packaging, and stain resistant fabrics, and they can build up in the body over time.

A new gel developed at UC Riverside delivers a continuous flow of oxygen right where it’s needed most, using a tiny battery-powered system. In high-risk mice, wounds healed in weeks instead of worsening. The innovation could dramatically reduce amputations—and may even open doors for lab-grown organs.

Researchers found that fat-derived molecules called epoxy-oxylipins rein in immune cells that can otherwise drive chronic disease. Using a drug to boost these molecules reduced pain faster and lowered harmful inflammatory cells. The discovery could pave the way for safer treatments for arthritis, heart disease, and other inflammation-related conditions.

The model reproduced key damage seen in real spinal cord injuries, including inflammation and scar formation. After treatment with fast moving “dancing molecules,” nerve fibers began growing again and scar tissue shrank. The results suggest the therapy could eventually help repair spinal cord damage.

They found that special support cells called astrocytes—located far from the actual injury—spring into action after damage. These “lesion-remote astrocytes” send out a protein signal, CCN1, that reprograms immune cells to efficiently clean up fatty nerve debris.

Immune cells formed in inflamed skin can travel through the blood and reach the joints, where they sometimes trigger inflammation. The key difference lies in the joint’s ability to keep those cells in check. This insight could help doctors identify warning signs early and prevent lasting joint damage.

The protein senses physical activity and pushes bone marrow stem cells to build bone instead of storing fat, slowing age-related bone loss. By targeting this “exercise sensor,” scientists believe they could create drugs that mimic exercise at the molecular level. The approach could protect fragile bones in people who are unable to stay active.

Researchers tested whether EEG brain scans could capture those signals and reroute them to spinal stimulators. The system can detect when a patient is trying to move, though finer control remains a challenge. Scientists hope future improvements could turn intention into action.

A common bacterium found in long-lasting wounds does not just resist drugs. It actively releases damaging molecules that overwhelm skin cells and stop them from repairing tissue. Researchers discovered that neutralizing these harmful molecules with antioxidants allows skin cells to recover and restart healing.

By blocking a protein linked to aging, the therapy restored healthy, shock-absorbing cartilage in old mice and injured joints, dramatically improving movement and joint function. Human cartilage samples from knee replacement surgeries also began regenerating when exposed to the treatment.

Researchers found that certain statins can latch onto a key muscle protein and trigger a tiny but harmful calcium leak inside muscle cells. That leak may weaken muscles directly or activate processes that slowly break them down, offering a long-sought explanation for statin-related aches.
