A blood test has been developed to detect Long Covid in children with 94% accuracy by identifying microclots in their blood samples. Long Covid symptoms in children can include fatigue, brain fog, pain, and shortness of breath. The test uses a microfluidic device to quantify microclots, showing significantly higher levels in pediatric Long Covid patients compared to healthy children. The test's accuracy is much higher than traditional methods, and it may offer a way to screen for Long Covid in larger populations and assess treatment responses. Additionally, patients with persistent SARS-CoV-2 spike protein in their blood had the highest microclot counts.

New tech can see a CPU's transistors in action — terahertz radiation can potentially steal data as a chip is running

Researchers at Adelaide University have developed a method using terahertz radiation to detect a chip's transistor activity while it is running, providing new insights into processor diagnostics. The process involves using a vector network analyzer to convert microwave signals into terahertz waves, allowing for the observation of transistor behavior. However, there are challenges to overcome, such as accurately testing complex, densely packed chips and the potential security risk of data theft as attackers could exploit this technology. Despite these issues, this advancement opens up new possibilities for processor testing and analysis.

Researchers have made advancements in three key areas of technology: 2D hard mask material, defect identification, and extreme photonic packaging. The use of chromium oxychloride as a hard mask material has shown promise due to its resistance to plasma etching and ability to create sharp, vertical structures. An AI model developed by MIT and Oak Ridge National Laboratory can classify and quantify defects in semiconductor materials using neutron-scattering data. Additionally, researchers at the National Institute of Standards and Technology have developed a photonic chip packaging process that can withstand extreme environments, such as deep space and nuclear reactors.
