White matter pathways allow distant parts of the brain to communicate, supporting memory, emotion, and language. One such pathway, the uncinate fasciculus, connects the front of the temporal lobe with regions of the frontal cortex involved in decision-making and social behavior. Despite its importance, little is known about the microscopic structure of this tract in the human brain. https://medicalxpress.com/news/2026-04-free-optical-imaging-enables-automated.html Fri, 24 Apr 2026 16:20:07 EDT news696257761 A cross-disciplinary team led by Prof. Qu Jianan from the Department of Electronic and Computer Engineering and Prof. Julie L. Semmelhack from the Division of Life Science at The Hong Kong University of Science and Technology (HKUST) has developed a powerful laser control technique. Functioning as a smart dimmer, it can selectively adjust the brightness of every pixel during laser scanning, and prevent unintended neural activation, thereby significantly enhancing the precision of all-optical brain manipulation and imaging. https://medicalxpress.com/news/2026-04-smart-laser-dimmer-neural-crosstalk.html Wed, 22 Apr 2026 16:00:12 EDT news696078062 A prototype of a new oral cancer diagnosis device, developed by the University of Liverpool, has demonstrated promising results during preliminary tests on histopathology specimens. https://medicalxpress.com/news/2025-01-device-early-oral-cancer.html Mon, 13 Jan 2025 11:52:27 EST news655991542 Amyloid deposition is a hallmark of neurodegenerative diseases such as Alzheimer's disease (AD) and Parkinson's disease (PD). The deposition process is described as a sigmoidal curve in which the misfolded proteins assemble into oligomers before fibril elongation. This dynamic process is accompanied by the misfolded monomer with more α-helix formed into abundant crosslinked β-sheet structure. Targeting the toxic accumulation may represent a promising strategy to slow or prevent disease initiation. https://medicalxpress.com/news/2023-08-potential-alzheimer-treatment-high-frequency-terahertz.html Wed, 02 Aug 2023 14:36:06 EDT news610205761 It is now possible to screen newborn babies for pyridoxine-dependent epilepsy (PDE), a severe inherited metabolic disorder. This screening promises to enable better and earlier treatment of the disease. To identify new biomarkers that can be used in the newborn screening protocol, also known as the neonatal heel prick, researchers at the Radboud University Medical Center joined forces with scientists at the Radboud University's FELIX laser laboratory. They published their findings in The Journal of Clinical Investigation. https://medicalxpress.com/news/2021-07-disease-biomarkers-newborn-epilepsy-screening.html Thu, 08 Jul 2021 11:23:24 EDT news544962201 Scientists have visualized and investigated a key molecular pathway that could one day help treat inflammation, diabetes, cancer, infectious diseases and potentially even COVID-19. https://medicalxpress.com/news/2021-05-drug-pathway-treatments-diabetes-cancer.html Tue, 11 May 2021 09:30:10 EDT news539944206 Amyloid fibrils are a type of self-assembled proteins/peptides that take on a stacked sheet-like formation. Amyloid fibril aggregates are known to be a cause of several diseases—including Alzheimer's—and therefore, it is of immense scientific interest to understand how these aggregates can be broken. Some types of amyloid fibrils also play a role in regulation of gene expression in some organisms. It is also thought that the fiber-like formats appearing in these aggregates act as scaffolds on which to cultivate biomaterials. Therefore, a suitable technique for breakdown or "dissociation" of amyloid protein fibrils is critical from the perspective of medical treatment, modification of biological structures and functions, and even biomaterial engineering. https://medicalxpress.com/news/2019-08-high-energy-lasers-alzheimer-disease-future.html Thu, 08 Aug 2019 10:33:08 EDT news484479178 Sun Tzu, the general of ancient China, wrote in his enduring military treatise "The Art of War" of the importance of knowing one's enemy. The idea resonates strongly with Athena Aktipis, a scholar of many titles at Arizona State University who studies cooperation among living things. https://medicalxpress.com/news/2018-09-crested-cactuses-ways-cancer.html Mon, 17 Sep 2018 09:30:01 EDT news456395225 Improving proton therapy for cancer treatment is one of the many advances in accelerator science that have been fast-tracked by a unique approach to academia-industry training, led by the Cockcroft Institute. The two programmes, which have produced 42 highly valued research fellows, are drawing to a conclusion and industry partners are warning of a skills chasm in the very near future unless further training is prioritised. https://medicalxpress.com/news/2015-04-proton-cancer-therapy-areas-threatened.html Tue, 21 Apr 2015 11:00:05 EDT news348832796 Medical operations have become almost commonplace, but the delicacy of medical procedures involving the brain and the spinal cord force physicians and patients to consider other alternatives. European researchers, however, could change this following their development of a laser for minimally invasive brain surgery. The achievement is a result of an interdisciplinary EU project that involved partners from seven European countries, creating a table-top solid-state laser system that can cut brain tissue with unprecedented precision. https://medicalxpress.com/news/2012-07-laser-ing-brain-surgery.html Tue, 03 Jul 2012 08:43:42 EDT news260523815 A team of scientists, led by the University of Liverpool, has made a major advance in the development of a diagnostic test for oesophageal cancer. The findings, achieved at STFC's ALICE accelerator facility, will lead to major improvements in the diagnosis, treatment and prognosis of the disease. https://medicalxpress.com/news/2012-02-breakthrough-diagnostic-oesophageal-cancer.html Wed, 08 Feb 2012 04:20:04 EST news247896621
