A Chip Off the Old Eye: Device Mimics Human Vision and Memory

The team’s research demonstrates a working device that captures, processes and stores visual information. With precise engineering of the doped indium oxide, the device mimics a human eye’s ability to capture light, pre-packages and transmits information like an optical nerve, and stores and classifies it in a memory system like the way our brains can.

Summary: Researchers developed a single-chip device that mimics the human eye’s capacity to capture, process, and store visual data.

This groundbreaking innovation, fueled by a thin layer of doped indium oxide, could be a significant leap towards applications like self-driving cars that require quick, complex decision-making abilities. Unlike traditional systems that need external, energy-intensive computation, this device encapsulates sensing, information processing, and memory retention in one compact unit.

As a result, it enables real-time decision-making without being hampered by processing extraneous data or being delayed by transferring information to separate processors.

Bioprinting personalized tissues and organs within the body: A breakthrough in regenerative medicine

In situ bioprinting, which involves 3D printing biocompatible structures and tissues directly within the body, has seen steady progress over the past few years. In a recent study, a team of researchers developed a handheld bioprinter that addresses key limitations of previous designs, i.e., the ability to print multiple materials and control the physicochemical properties of printed tissues. This device will pave the way for a wide variety of applications in regenerative medicine, drug development and testing, and custom orthotics and prosthetics.

The emergence of has resulted in substantial improvements in the lives of patients worldwide through the replacement, repair, or regeneration of damaged tissues and organs. It is a promising solution to challenges such as the lack of organ donors or transplantation-associated risks. One of the major advancements in regenerative medicine is on-site (or “in situ”) bioprinting, an extension of 3D , which is used to directly synthesize tissues and organs within the human body. It shows great potential in facilitating the repair and regeneration of defective tissues and organs.

Although significant progress has been made in this field, currently used in situ bioprinting technologies are not devoid of limitations. For instance, certain devices are only compatible with specific types of bioink, while others can only create small patches of tissue at a time. Moreover, their designs are usually complex, making them unaffordable and restricting their applications.

A Conductive Self-Healing Hydrogel to Create Flexible Sensors

Recent advancements in the field of electronics have enabled the creation of smaller and increasingly sophisticated devices, including wearable technologies, biosensors, medical implants, and soft robots. Most of these technologies are based on stretchy materials with electronic properties.

While material scientists have already introduced a wide range of flexible materials that could be used to create electronics, many of these materials are fragile and can be easily damaged. As damage to materials can result in their failure, while also compromising the overall functioning of the system they are integrated in, several existing soft and conductive materials can end up being unreliable and unsuitable for large-scale implementations.

Researchers at Harbin University of Science and Technology in China recently developed a new conductive and self-healing hydrogel that could be used to create flexible sensors for wearables, robots or other devices. This material and its composition was outlined in the Journal of Science: Advanced Materials and Devices.

‘Concerning’ CT scans may cause unnecessary hospitalization for some pulmonary embolism patients

Of approximately 250,000 Americans diagnosed with acute pulmonary embolism (PE) in emergency departments each year, most are hospitalized.

But new Michigan Medicine research, published in JAMA Network Open, finds that some patients with PE, a blood clot in one or more , may be hospitalized unnecessarily due to computed tomography (CT) imaging results rather than clinical risk factors.

Approximately 40% of the patients in the study had low-risk , as defined by the Pulmonary Embolism Severity Index, or PESI score. Roughly half of the low risk patients had CT imaging features that physicians consider “concerning,” and these patients fared just as well in the hospital as those whose CT scans showed no concerning findings.

Mint DIS 2023

Generative artificial intelligence (AI) has put AI in the hands of people, and those who don’t use it could struggle to keep their jobs in future, Jaspreet Bindra, Founder and MD, Tech Whisperer Lt. UK, surmised at the Mint Digital Innovation Summit on June 9.

“We never think about electricity until it’s not there. That’s how AI used to be. It was always in the background and we never thought about it. With generative AI it has come into our hands, and 200–300 million of us are like, wow!” said Bindra.

He noted that while AI won’t replace humans at their jobs, someone using AI very well could. He urged working professionals to “recalibrate” and embrace generative AI as a “powerful tool” created by humans, instead of looking at it as a threat.

ChatGPT AI Shines in Challenging Medical Cases

Summary: A novel study put the diagnostic prowess of generative AI, specifically the chatbot GPT-4, to the test, yielding promising results.

The study involved evaluating the AI’s diagnostic accuracy in handling complex medical cases, with GPT-4 correctly identifying the top diagnosis nearly 40% of the time and including the correct diagnosis in its list of potential diagnoses in 64% of challenging cases.

The success of AI in this study could provide new insights into its potential applications in clinical settings. However, more research is needed to address the benefits, optimal use, and limitations of such technology.

Keith Ward — Why is Consciousness so Mysterious?

How can the mindless microscopic particles that compose our brains ‘experience’ the setting sun, the Mozart Requiem, and romantic love? How can sparks of brain electricity and flows of brain chemicals literally be these felt experiences or be ‘about’ things that have external meaning? How can consciousness be explained?
