A new tool has been developed to detect skin cancer; it utilizes a biosensor that can identify small changes in the characteristics of cells. | Clinical And Molecular Dx.
The continuous improvement of circuits and electronic components is vital for the development of new technologies with enhanced capabilities and unique characteristics. In recent years, most electronics engineers have been specifically focusing on reducing the size of transistors, while retaining a low power consumption.
Researchers at University of Science and Technology Beijing recently introduced a new pseudo-CMOS architecture based on self-biased molybdenum disulfide transistors. This architecture, outlined in Nature Electronics, could be used to create highly performing inverters, gate circuits, and other device components.
“The development of integrated circuits (ICs) for efficient computing with low power is a global hot topic and a focus of international competition in cutting-edge fields,” Zheng Zhang, co-author of the paper, told Tech Xplore.
This Review explores the development of ingestible electronics and provides a step-by-step guide for the design of ingestible electronic capsules at the system level.
Tardigrades are often considered the most endearing invertebrates, akin to the capybara of their realm, yet their significance surpasses mere charm.
This year, researchers from Harvard Medical School, the University of North Carolina at Chapel Hill, and Marshall University in Huntington, West Virginia, discovered that when the tardigrades are under stress, their bodies produce unstable free radicals of oxygen and an unpaired electron.

The case vendor shows off a new prototype DK-07 desk with a transparent OLED screen that can display images atop your PC components.
Roughly 1 in 2 wearers of ventricular assist devices are diagnosed with an infection. The reason for this is the thick cable for the power supply. ETH Zurich researchers have now developed a solution to mitigate this problem.
For many patients waiting for a donor heart, the only way to live a decent life is with the help of a pump attached directly to their heart. This pump requires about as much power as a TV, which it draws from an external battery via a seven-millimeter-thick cable. The system is handy and reliable, but it has one big flaw: Despite medical treatment, the point at which the cable exits the abdomen can be breached by bacteria.

A new stamp-sized ultrasound sticker developed by MIT can help monitor organ stiffness and detect diseases and tumor progression.
The MIT-developed sensor could detect signs of disease such as liver and kidney failure, and the progression of solid tumors.
Chemists at RIKEN have developed a method for making synthetic derivatives of the natural dye indigo that doesn’t require harsh conditions. This discovery could inspire advances in electronic devices, including light-responsive gadgets and stretchy biomedical sensors.
Semiconductors based on organic molecules are attracting much interest because—unlike conventional rigid semiconductors based on silicon—they could be flexible, ductile and lightweight, opening up new possibilities for designing semiconductor devices.
Organic molecules also have the advantage of realizing a broad range of structures. “Organic semiconductors have flexibility in molecular design, enabling them to adopt new functionalities,” says Keisuke Tajima of the RIKEN Center for Emergent Matter Science, who led the research.
A new type of ultra-sensitive sensor has been made to detect incredibly low levels of lead ions in water. This advanced sensor may pave the way for developing next-generation water quality monitoring systems.
What distinguishes the sensor is its capacity to detect lead ions at concentrations as low as one femtomole per liter of water, demonstrating an incredibly high degree of sensitivity.
According to the University of California, San Diego experts, this range is “one million times” more sensitive than any known sensing technologies for water contamination monitoring.
