Scientists Identify Protein That Heightens Neurodegenerative Disease Credit: UT Southwestern A fluorescent image displays reactive gliosis – a condition found in many neurodegenerative diseases – in the cerebral cortex induced by astrocyte-expressed GADD45G, the protein product of the Gadd45g gene. Reactive astrocytes are shown in red and reactive microglia are green, both common glial cell types.PreviousNext Newswise — DALLAS – May 29, 2025 – UT Southwestern Medical Center scientists have identified a protein that appears to act as a master control switch for reactive gliosis, a prominent feature of many neurodegenerative diseases that is thought to contribute to their pathology. The researchers’ findings, published in Neuron, could eventually lead to new treatments for Alzheimer’s, Parkinson’s, and Huntington’s diseases and other neurodegenerative conditions. “Reactive gliosis can help the nervous system adapt to stressful conditions to continue healthy functioning, but it can also b...

Using Deep Learning for Brain Imaging Data Analysis ​​​​​​​Deep learning (DL) is a type of artificial intelligence (AI) that utilizes artificial neural networks (ANNs) to process data through two or more layers, each of which can recognize complex features of the data. All deep learning models are built on fundamental computational units that take in inputs, process them, and produce outputs—either forwarding them to the next layer or using them as the final result.1 Recent advancements in the technological capabilities of central processing units (CPUs), graphics processing units (GPUs), and learning algorithms, combined with the availability of big data, have allowed DL to become one of the most powerful AI technologies. As a result, DL has been incorporated into various applications, some of which include computer vision, natural language processing, and speech improvement. DL has also been widely used to support the analysis of medical images, which can include the classification,...

Sound waves in air deflect intense laser pulses

Image
  Sound waves in air deflect intense laser pulses Sound idea: laser light passes between a ultrasound transducer-reflector array that creates a Bragg grating of air. The laser beam interacts with this grating and is deflected without travelling through a solid medium. (Courtesy: Science Communication Lab for DESY) Ultrasound waves in air have been used to manipulate powerful laser beams – in a first claimed by researchers in Germany. The team’s acousto-optic Bragg grating could lead to new and useful ways to manipulate light. From gravitational wave detection to semiconductor fabrication, much of modern science and technology relies on the precise control of laser light. “Optical elements like gratings, lenses or modulators have always formed the basic ingredients behind optical devices including lasers, microscopes and atomic clocks, which have enabled many breakthroughs in various scientific fields,” explains Christoph Heyl at DESY, who led the research. However, demands for hig...

Traffic Noise Evaluation

  Traffic Noise Evaluation   Traffic noise evaluation involves the measurement, analysis, and assessment of noise generated by vehicles on roadways, especially in urban and suburban environments. This process is essential for understanding the impact of noise pollution on public health, environmental quality, and overall urban livability. By using advanced sound level meters, modeling software, and geographic data, professionals assess how noise levels vary with traffic volume, vehicle types, road conditions, and time of day. These evaluations help in formulating mitigation strategies such as sound barriers, low-noise pavements, urban green buffers, and traffic flow optimization. The goal of traffic noise evaluation is not only to comply with legal noise limits but also to create quieter, healthier, and more sustainable cities.

ADAS Adds Complexity To Automotive Sensor Fusion Advancements in combining sensors enabling intelligent, distributed processing and standardized communication of object data. Sensor fusion is becoming increasingly popular and more complex in automotive designs, integrating multiple types of sensors into a single chip or package and intelligently routing data to wherever it is needed. The primary goal is to bring together information from cameras, radar, lidar, and other sensors in order to provide a detailed view of what’s happening inside and outside of a vehicle. In the newest designs, sensor fusion often occurs in zonal controllers or central compute modules. These devices act as intermediaries, collecting data from different sensors and transmitting it to a central processing unit. The exact location of sensor fusion, as well as which sensors are combined, can vary depending on the vehicle’s architecture and the manufacturer’s approach. There are two main options for fusing togethe...
