Regular aerobic exercise reshapes the autonomic nerves that regulate the heart, producing asymmetric remodeling in the stellate ganglia of rats—more right-side neurons, larger left-side neurons, and an overall shrinkage in nerve volume—hinting at side-specific implications for treating heart rhythm disorders and chest pain; human relevance requires further study.
New human data confirm that heart muscle cells can regrow after a heart attack, challenging the long-held belief that damage is permanent. By analyzing living heart tissue from bypass patients, researchers observed increased cardiomyocyte mitosis in the damaged regions, suggesting a regenerative process alongside scarring. While not yet reversing heart failure, these findings pave the way for therapies that boost the heart’s natural cell production to repair damage and potentially reduce reliance on transplantation.
A new study shows the mechanical force of heartbeats slows cancer growth by altering tumor cell gene activity. In mice and lab tissue, beating hearts reduced cancer proliferation and epigenetic markers linked to growth, with Nesprin-2 identified as a key sensor of heartbeat-induced forces. This points to potential mechanical therapies (like bands applying heartbeat-like force) or drugs that mimic the effect, though safety and timing must be established before human use.
New research suggests the heart’s rhythmic beating creates mechanical strain that suppresses cancer growth in heart tissue. In mouse experiments, non‑beating transplanted hearts rapidly developed cancer, while beating native hearts largely resisted it and restricted cancer to the outer layers; engineered heart tissue that beat only when stimulated with calcium showed a similar pattern. This mechanical effect could help explain why heart tumors are extraordinarily rare in mammals.
Scientists have linked the heart’s inner trabeculae, sketched by Leonardo da Vinci, to adult heart function and cardiovascular disease risk. Using fractal analysis, MRI data, and UK Biobank data from nearly 18,100 participants, researchers showed trabeculae shape affects cardiac performance and identified 16 genetic loci related to their development, suggesting embryonic origins influence disease risk and could inform clinical understanding.
Diana Warren, 55, from Essex, collapsed during a leisurely bike ride and was found to have an atrial septal defect—a hole in her heart—that had gone undiagnosed for over five decades. After unsuccessful keyhole attempts, she underwent open-heart surgery in April 2024 with a pacemaker. Now recovered, she plans to cycle 54 miles from London to Brighton to raise funds for the British Heart Foundation.
Researchers used fractal theory, MRI imaging, and genetics on 18,096 UK Biobank participants to show that the heart’s trabeculae—the snowflake-like muscular network—help determine cardiac performance and disease risk, a finding that builds on Leonardo da Vinci’s centuries-old observations and marks a first step toward a deeper understanding of how trabeculae form and function.
Ray J disclosed that his heart is only beating at about 25%, and doctors gave him a likely deadline of 2027, after extensive alcohol and drug use damaged his heart; he says '2027 is definitely a wrap' and that he almost died from pneumonia after heavy drinking and Adderall, calling his past behavior a serious mistake while thanking his family for support.
Regular aerobic exercise not only strengthens the heart but also rewires its nerve control system in a side-specific manner, potentially leading to more targeted treatments for heart conditions like arrhythmias and angina, as shown by recent rat studies that reveal structural changes in the heart's nerve clusters.
A man from Pleasantville, New Jersey, was arrested for stealing two valuable instruments from Heart's band during their 2025 Summer Tour, with one instrument sold and the other missing; the band has offered a reward for their safe return.
A man from New Jersey was arrested for stealing irreplaceable instruments from the band Heart, including a custom purple Telecaster and a vintage mandolin, which are highly valued by the band members. The theft occurred at the Hard Rock Casino & Hotel, and authorities are urging the return of the instruments, emphasizing their sentimental and artistic importance. The band continues their tour despite the incident.
Heart's summer tour faced a setback when two irreplaceable instruments, a custom purple Telecaster and a vintage mandolin, were stolen from the venue before their first show. The band is offering a reward and urging anyone with information to come forward, but the tour will continue despite the loss.
Drinking a glass of red wine nightly may offer health benefits like improved heart health and reduced inflammation due to its antioxidants, such as resveratrol. However, these benefits are not sufficient to outweigh the risks associated with alcohol consumption, including disrupted sleep, medication interactions, increased cancer risk, and potential for alcohol dependence. While moderate wine consumption can be part of a healthy lifestyle, similar benefits can be obtained from antioxidant-rich foods without the associated risks of alcohol.
New research from Karolinska Institutet and Columbia University reveals that the heart has its own complex nervous system, or "mini-brain," capable of independently regulating the heartbeat. This discovery, made through studies on zebrafish, challenges traditional views and could lead to new treatments for heart diseases like arrhythmias. The study highlights the heart's neural network's complexity and its potential interaction with the brain during stress or disease, offering new therapeutic targets.
To mark the recent solar eclipse, Jimmy Fallon had rock legends Heart perform Total Eclipse of the Heart on a New York rooftop during the actual event, with Fallon joining in by singing the "turn around" part while actually turning around. Heart also performed their classic hit Barracuda in the studio. The group has announced their Royal Flush tour for 2024, with shows across North America, the UK, and Europe, including festival dates and arena gigs.
