The Science of Near-Death Experiences: Empirically investigating brushes with the afterlife

Near-death experiences have gotten a lot of attention lately. The 2014 movie Heaven Is for Real, about a young boy who told his parents he had visited heaven while he was having emergency surgery, grossed a respectable $91 million in the United States. The book it was based on, published in 2010, has sold some 10 million copies and spent 206 weeks on the New York Times best-seller list. Two recent books by doctors—Proof of Heaven, by Eben Alexander, who writes about a near-death experience he had while in a week-long coma brought on by meningitis, and To Heaven and Back, by Mary C. Neal, who had her NDE while submerged in a river after a kayaking accident—have spent 94 and 36 weeks, respectively, on the list. (The subject of The Boy Who Came Back From Heaven, published in 2010, recently admitted that he made it all up.) Science, cool facts, mind, emotion, breakthrough, science.

Their stories are similar to those told in dozens if not hundreds of books and in thousands of interviews with “NDErs,” or “experiencers,” as they call themselves, in the past few decades. Though details and descriptions vary across cultures, the overall tenor of the experience is remarkably similar. Western near-death experiences are the most studied. Many of these stories relate the sensation of floating up and viewing the scene around one’s unconscious body; spending time in a beautiful, otherworldly realm; meeting spiritual beings (some call them angels) and a loving presence that some call God; encountering long-lost relatives or friends; recalling scenes from one’s life; feeling a sense of connectedness to all creation as well as a sense of overwhelming, transcendent love; and finally being called, reluctantly, away from the magical realm and back into one’s own body.

This is interesting because it has today type applications, but I wonder, what about a 3D printed body? Remember the movie Starship Troopers when they repaired that guy’s leg in the water tank thing? I’ve seen similar devices in other movies. Could be easier than removing the head completely and safer, when the ability to print human tissues is feasible.

Psychosensory electronic skin technology for future AI and humanoid development

Professor Jae Eun Jang’s team in the Department of Information and Communication Engineering has developed electronic skin technology that can detect “prick” and “hot” pain sensations like humans. This research result has applications in the development of humanoid robots and prosthetic hands in the future.

Scientists are continuously performing research to imitate tactile, olfactory and palate senses, and is expected to be the next mimetic technology for various applications. Currently, most tactile sensor research is focused on physical mimetic technologies that measure the pressure used for a robot to grab an object, but psychosensory tactile research on mimicking human tactile sensory responses like those caused by soft, smooth or rough surfaces has a long way to go.

Professor Jae Eun Jang’s team has developed a tactile sensor that can feel and temperature like humans through a joint project with Professor Cheil Moon’s team in the Department of Brain and Cognitive Science, Professor Ji-woong Choi’s team in the Department of Information and Communication Engineering, and Professor Hongsoo Choi’s team in the Department of Robotics Engineering. Its key strengths are that it has simplified the sensor structure and can measure pressure and temperature at the same time. Furthermore, it can be applied on various tactile systems regardless of the measurement principle of the sensor.

A deep learning technique for context-aware emotion recognition

A team of researchers at Yonsei University and École Polytechnique Fédérale de Lausanne (EPFL) has recently developed a new technique that can recognize emotions by analyzing people’s faces in images along with contextual features. They presented and outlined their deep learning-based architecture, called CAER-Net, in a paper pre-published on arXiv.

For several years, researchers worldwide have been trying to develop tools for automatically detecting by analyzing images, videos or audio clips. These tools could have numerous applications, for instance, improving robot-human interactions or helping doctors to identify signs of mental or neural disorders (e.g.„ based on atypical speech patterns, facial features, etc.).

So far, the majority of techniques for recognizing emotions in images have been based on the analysis of people’s facial expressions, essentially assuming that these expressions best convey humans’ emotional responses. As a result, most datasets for training and evaluating emotion recognition tools (e.g., the AFEW and FER2013 datasets) only contain cropped images of human faces.

Quantum engineering atomically smooth single-crystalline silver films

Ultra-low-loss metal films with high-quality single crystals are in demand as the perfect surface for nanophotonics and quantum information processing applications. Silver is by far the most preferred material due to low-loss at optical and near infrared (near-IR) frequencies. In a recent study now published on Scientific Reports, Ilya A. Rodionov and an interdisciplinary research team in Germany and Russia reported a two-step approach for electronic beam evaporation of atomically smooth single crystalline metal films. They proposed a method to establish thermodynamic control of the film growth kinetics at the atomic level in order to deposit state-of-the-art metal films.

The researchers deposited 35 to 100 nm thick, single-crystalline silver with sub-100 picometer (pm) with theoretically limited optical losses to form ultrahigh-Q nanophotonic devices. They experimentally estimated the contribution of material purity, material grain boundaries, surface roughness and crystallinity to the optical properties of metal films. The team demonstrated a fundamental two-step approach for single-crystalline growth of silver, gold and aluminum films to open new possibilities in nanophotonics, biotechnology and superconductive quantum technologies. The research team intends to adopt the method to synthesize other extremely low-loss single-crystalline metal films.

Optoelectronic devices with plasmonic effects for near-field manipulation, amplification and sub-wavelength integration can open new frontiers in nanophotonics, quantum optics and in quantum information. Yet, the ohmic losses associated in metals are a considerable challenge to develop a variety of useful plasmonic devices. Materials scientists have devoted research efforts to clarify the influence of metal film properties to develop high performance material platforms. Single-crystalline platforms and nanoscale structural alterations can prevent this problem by eliminating material-induced scattering losses. While silver is one of the best known plasmonic metals at optical and near-IR frequencies, the metal can be challenging for single-crystalline film growth.
