In the treatment of larger narrowed blood vessels, drug-coated balloon catheters have been shown to deliver lasting and effective outcomes. Their minimally invasive nature makes them a viable alternative to stents. These findings, from a research team led by cardiologist Professor Bruno Scheller at Saarland University, have now been validated by an international study involving over 3,300 patients. The results were recently presented at TCT, the world’s largest conference on transcatheter cardiovascular therapeutics, held from 25 to 28 October in San Francisco, USA. Professor Scheller originally developed the method two decades ago and has continuously refined it through ongoing research.

A study published in the journal Nature Climate Change by an international team of scientists, from the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea, presents new evidence that ocean turbulence and a process known as “horizontal stirring” will increase dramatically in the Arctic and Southern Oceans due to human-induced Global Warming and decreasing sea ice coverage.

A new deep learning framework can accurately classify four molecular subgroups of medulloblastoma and predict critical genetic risk factors using magnetic resonance imaging, according to a study by researchers from China. The artificial intelligence model achieved a median accuracy of 77.5% for subgroup classification and up to 91.3% for predicting high-risk genetic alterations. This approach could help clinicians stratify risk and tailor therapies without invasive testing.

A study by researchers from the UK, Ghana and the USA - and led by the University of Plymouth (UK) used thermal imaging technology and other sensors to measure the leaf temperatures found at CO₂ levels forecast to occur in 2050. It found that temperatures within the forest canopies rose by around 1.3°C as a direct consequence of increases in CO₂ – from an average of 21.5°C under current conditions to 22.8°C at the predicted 2050 CO₂ levels. They believe that as well as having a direct impact on leaf pore structure, it could impact trees’ ability to transmit water back into the environment, which would have a knock-on effect on the water cycle globally.

Computer-controlled sub-aperture polishing technology is crucial for achieving high-precision optical components. However, this convolution material removal method introduces a significant number of mid-spatial frequency(MSF) errors. To address this issue, scientist in China propose a novel controllable spiral magnetorheological finishing method that disrupts the mechanism of conventional constant tool influence function (TIF) convolution material removal to control convolution MSF error . This variable convolution kernel(TIF) sub-aperture polishing method provides a new idea for full-band error cooperative control.
