Researchers at the University of Geneva used artificial intelligence to map gut microbiota subspecies and develop a stool-based test that identified about 90% of colorectal cancers, approaching colonoscopy’s 94% detection rate. If validated in ongoing trials, this non-invasive method could replace routine screening with colonoscopies reserved for positives, while expanding screening accessibility.
A BMJ study in 3,068 Chinese women found that menstrual blood collected on a sanitary pad and strip could detect HPV and CIN2/3 with about 94.7% sensitivity, comparable to clinician-collected samples (≈92.1%), though specificity was lower. Negative predictive value and referral rates were similar between methods. The results suggest menstrual-blood testing could become a standardized, non-invasive alternative or supplement to cervical screening, but larger, more diverse trials are needed before clinical adoption.
Researchers used non-invasive transcranial ultrasound stimulation to target the nucleus accumbens, a deep brain structure involved in motivation, and found it enhanced reward learning in humans within 60 seconds, suggesting potential for treating mental health disorders without surgery.
A groundbreaking non-invasive liver cancer treatment called histotripsy has been administered to the first NHS patient in the UK, using focused ultrasound waves to destroy cancerous tissue, offering a faster, safer alternative to traditional therapies and marking a significant advancement in cancer care.
Ultrasound technology, particularly histotripsy, is emerging as a promising non-invasive method for treating cancer, offering targeted destruction of tumors with minimal side effects, and is now approved in the US and UK, potentially revolutionizing cancer care by reducing reliance on surgery, chemotherapy, and radiation.
Researchers have developed a novel ultrasound device capable of simultaneously stimulating multiple precise points in the brain non-invasively, using low-intensity ultrasound to reduce risks and enable visualization of brain activity, with potential applications for treating neurological and psychiatric disorders.
New specially formulated eye drops containing pilocarpine and diclofenac can rapidly improve near vision in presbyopia patients, with effects lasting up to two years and minimal side effects, offering a promising non-invasive alternative to glasses and surgery.
Researchers have developed special eye drops containing pilocarpine and diclofenac that can improve near vision in presbyopia patients, potentially reducing the need for reading glasses. The study showed significant and sustained improvements over two years, though further research is needed to confirm safety and effectiveness. These drops offer a promising non-invasive alternative for those who cannot undergo surgery or prefer to avoid glasses.
Researchers have developed a novel ultrasound helmet that can non-invasively target and modulate deep-brain structures with high precision, potentially transforming the study and treatment of neurological and psychiatric conditions like Parkinson's disease and depression.
Researchers from UCL and Oxford have developed a non-invasive ultrasound helmet capable of precisely stimulating deep brain regions, such as the thalamus, without surgery, opening new avenues for neuroscience research and treatment of disorders like Parkinson's disease. The device uses 256 elements to focus ultrasound beams, demonstrated to modulate neural activity in human volunteers, with potential for clinical applications and personalized therapies.
A study demonstrates that combining AI with non-invasive brain devices significantly enhances their performance, enabling a paralysed man to control a robotic arm with 93% success in a task, and improving task completion speed for others, thereby potentially improving quality of life.
A new AI framework called CTCAIT can detect neurological disorders like Parkinson's, Huntington's, and Wilson disease with over 90% accuracy by analyzing speech patterns, offering a promising non-invasive tool for early diagnosis and monitoring across multiple languages.
A new study suggests that radio waves can be used to safely and painlessly restore the sense of smell by targeting brain nerves, showing promise for treating olfactory loss without surgery or chemicals, though further research on affected individuals is planned.
A study shows trained dogs can detect Parkinson's disease from skin swabs with up to 98% accuracy, potentially enabling earlier and non-invasive diagnosis of the disease.
A study demonstrates that analyzing skin sebum through non-invasive swabs can detect early signs of Parkinson's disease up to seven years before symptoms appear, using chemical biomarkers identified by mass spectrometry, potentially enabling earlier diagnosis and intervention.
