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.
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.

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.
