Long-time trapping of a single electron could allow the particle to be used as an efficient quantum bit.
A new type of quantum holography which uses entangled photons to overcome the limitations of conventional holographic approaches could lead to improved medical imaging and speed the advance of quantum information science.
There’s a mini second genome inside your cells, but no one could figure out how to edit it — until now.
Scientists have discovered the first evidence for a rare type of stellar explosion, or supernova in the Milky Way. This intriguing object lies near the center of our galaxy in a supernova remnant called Sagittarius A East (Sgr A East). Chandra data revealed that Sgr A East may belong to a spec.
Human-Autonomy Interaction, Collaboration and Trust — Dr. Julie Marble, JHU Applied Physics Laboratory (APL)
Dr. Julie Marble is a senior scientist at the Johns Hopkins University Applied Physics Laboratory (JHUAPL) leading research in human-autonomy interaction, collaboration and trust.
Dr. Marble earned her PhD in Human Factors/Cognitive Psychology from Purdue University. After graduating from Purdue University, she joined the Idaho National Laboratory (INL), one of the national laboratories of the United States Department of Energy involved in nuclear research, first in the Human Factors group and then the Human and Robotic Systems group.
Following INL, she joined Sentient Corporation, where as CEO she led a DARPA Broad Agency Announcement BAA on Neuro-Technology for Intelligence Analysts and led research on to develop an intelligent decision aid to perform just-in-time maintenance on Navy helicopters.
Dr. Marble then worked as a Senior Scientist at the US Nuclear Regulatory Commission leading international and US studies on Human-Reliability Analysis methods in this vital domain and related to this, she is internationally recognized for her work, and is co-author of the SPAR-H method (Standardized Plant Analysis Risk Human Reliability Analysis), the most commonly used method of human reliability analysis in the US. She is also co-developer of the Cultural Affective Model, which integrates cultural impacts into human reliability in order to predict operator behavior.
WASHINGTON — The Defense Advanced Research Projects Agency wants to hear from the space industry about their capabilities to manufacture large structures on the moon.
This is a new project that DARPA announced Feb. 5 called “Novel Orbital and Moon Manufacturing, Materials and Mass-efficient Design.”
In the past few years, researchers have turned increasingly to data science techniques to aid problem-solving in organic synthesis.
We can immediately supersede the Mojo Vision approach for retinal projection, with an interim projection system using metalenses. The Mojo Lens approach is to try to put everything, including the television screen, projection method and energy source onto one contact lens. With recent breakthroughs in scaling up the size of metalenses, an approach utilizing a combination of a contact metalens and a small pair of glasses can be utilized. This is emphatically not the Google Glass approach, which did not use modern metalenses. The system would work as follows:
1)Thin TV cameras are mounted on both sides of a pair of wearable glasses.
2)The images from these cameras are projected via projection metalenses in a narrow beam to the center of the pupils.
3)A contact lens with a tiny metalens mounted in the center, directly over the pupil, projects this projected beam outwards, through the pupil, onto the full width of the curved retina.
The end result would be a 360 degree, full panorama image. This image can either be a high resolution real time vision of the wearer’s surroundings, or can be a projection of a movie, or augmented reality superimposed on the normal field of vision. It can inherently be full-color 3D. Of course such a system will be complemented with ear phones. Modern hearing aids are already so small they can barely be seen, and have batteries that last a week. A pair of ear phones will also allow full 3D sound and also will be the audible complement of augmented vision.
Cameras in cell phones using traditional lenses are already very thin, and even they could be used for an experimental system of this type, but the metalens cameras will make this drastically thinner. The projection lens system must work in combination with the lens over the pupil. This also means that when the glasses are removed, the contact lens must also be removed, or the vision will be distorted.
The end result will be a pair of glasses, not quite as thin as an ordinary pair of glasses, but still very thin and comfortable. Instead of trying to mount the power source in the contact lens, like Mojo Vision is trying to do, a small battery would be mounted in the glasses. Mojo Vision is probably going to have to do something similar for the power source: put the battery in a small pair of glasses that projects the energy onto its contact lens.
As commercial space companies increase the cadence of successful rocket launches, access to space is becoming more routine for both government and commercial interests. But even with regular launches, modern rockets impose mass and volume limits on the payloads they deliver to orbit. This size constraint hinders developing and deploying large-scale, dynamic space systems that can adapt to changes in their environment or mission.
