"Breakthrough Fridge Design Accelerates Quantum Computing"

Scientists at the National Institute of Standards and Technology (NIST) have developed a new prototype refrigerator that can achieve temperatures close to absolute zero much more quickly and efficiently than current models. This breakthrough could significantly reduce the time and cost associated with quantum computing and other scientific experiments requiring extremely low temperatures. The new design improves the efficiency of pulse tube refrigerators (PTRs) by preventing helium waste, potentially saving 27 million watts of power annually and reducing global energy costs by $30 million. The technology is expected to accelerate advancements in quantum computing and benefit the cryogenics industry.

"Revolutionizing Glucose Monitoring: Using a Phone's Compass for Accurate Measurements"

Researchers at NIST have developed a method to use a smartphone's compass to analyze biomarkers in body fluids, potentially allowing for the monitoring and diagnosis of diseases. In a proof-of-concept study, they successfully measured glucose and pH levels in various liquids. The technique involves a small magnet embedded in a hydrogel strip that interacts with the smartphone's magnetometer. While more testing is needed for biological fluids, this innovation could lead to affordable and portable medical sensing capabilities, with potential applications in healthcare and environmental monitoring.

"Revolutionary Smartphone Compass Technique for High-Sensitivity Blood Glucose Measurement"

Researchers at NIST have developed a technique using the magnetometer in smartphones to measure blood glucose levels with high accuracy. By attaching a tiny well containing a solution and a strip of hydrogel to a cellphone, they were able to detect changes in magnetic field strength caused by the hydrogel's reaction to glucose or pH levels. This low-cost method could lead to the development of inexpensive glucose testing kits that can be attached to smartphones, potentially revolutionizing at-home blood glucose monitoring.

"Cellphone Compass Measures Vital Health Compounds: NIST Study"

Researchers at NIST have developed a technique that utilizes an ordinary cellphone magnetometer to measure the concentration of glucose and pH levels with high accuracy, using magnetized hydrogel test strips. This method has the potential to rapidly and inexpensively measure various biomedical properties for disease monitoring and environmental toxin detection. The proof-of-concept study demonstrated the ability to measure glucose concentrations as small as a few millionths of a mole, and future improvements could enable the detection of DNA strands, specific proteins, and histamines at extremely low concentrations. The technique offers an inexpensive way to conduct testing, even in resource-limited locations, and could have applications in fields such as healthcare, environmental science, and food and beverage production.

"Key Insights from 2024 Surfside Condo Collapse Investigation"

Investigators are focusing on construction flaws in the pool deck as the cause of the 2021 collapse of the Champlain Towers South condominium in Surfside, Florida, which resulted in 98 deaths. The National Institute of Standards and Technology (NIST) has found that the concrete used in the pool deck and supporting columns was weaker than required by building codes, and the added weight from planters contributed to increased stress. While the collapse likely initiated in the pool deck, NIST has not ruled out a failure initiation in some part of the tower structure. The investigation is examining at least 40 potential failure hypotheses and aims to complete its technical work by summer, with a draft report and recommendations expected in May 2025.
