Chinese researchers turned the immune response to organ transplant rejection to cure cancer with a 90% success rate.
The question of life beyond this planet has transfixed humans for centuries. This film reveals the supporting evidence we’ve all been looking for.
“Surgery means extensive recovery time and can significantly impact patient health. Our system doesn’t require surgery because we use a conventional stent, the catheter, as a delivery vehicle,” said W. Hong Yeo, the Harris Saunders Jr. Endowed Professor and an associate professor in the George W. Woodruff School of Mechanical Engineering.
Made from ultra-thin, flexible silicone, these nanosensors can be embedded in almost anything, from pacifiers to catheters. But size was just one element the researchers needed to consider when developing this device; accuracy was just as important.
Hong Yeo holds an in-stent nanomembrane sensor that can detect intracranial pressure.
A car accident, football game, or even a bad fall can lead to a serious or fatal head injury. Annually, traumatic brain injuries (TBI) cause half a million permanent disabilities and 50,000 deaths. Monitoring pressure inside the skull is key to treating TBI and preventing long-lasting complications.
Most of these monitoring devices are large and invasive, requiring surgical emplacement. But Georgia Tech researchers have recently created a sensor smaller than a dime. The miniature size offers huge benefits.
Scientists from South Korea have advanced lithium-ion battery technology through nanotechnology and a new hybrid composite material.
The immune system fights germs on the skin, in the tissues of the body, and in bodily fluids such as blood. It is made up of the innate (general) immune system and the adaptive (specialized) immune system. These two systems work closely together and take on different tasks.
The innate immune system is the body’s first line of defense against intruders. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the “non-specific” immune system. It acts very quickly – for instance, it makes sure that bacteria that have entered the skin through a small wound are detected and destroyed on the spot within a few hours. But the innate immune system can’t always stop germs from spreading.
This Review explores how experimental models of metastasis, such as mouse models and cell cultures, can complement the (multi)omics analysis of human metastasis samples, thereby filling knowledge gaps left by model studies and validating the findings from human sequencing data.
Bcl11a sustains hematopoietic stem cell functionality but contributes to dysfunction as aging progresses.
Aging is a complex, progressive, and irreversible biological process that entails numerous structural and functional changes in the organism. These changes affect all bodily systems, reducing their ability to respond and adapt to the environment. Chronic inflammation is one of the key factors driving the development of age-related diseases, ultimately causing a substantial decline in the functional abilities of older individuals. This persistent inflammatory state (commonly known as “inflammaging”) is characterized by elevated levels of pro-inflammatory cytokines, an increase in oxidative stress, and a perturbation of immune homeostasis. Several factors, including cellular senescence, contribute to this inflammatory milieu, thereby amplifying conditions such as cardiovascular disease, neurodegeneration, and metabolic disorders.
A new AI framework inspired by human memory could make machines more efficient, adaptive, and capable of reasoning. A recent paper published in the journal Engineering presents a novel approach to artificial intelligence by modeling it after how human memory functions. The research aims to overco
