New Vertical Farming BioTech Grows Plants In The Dark

  Square Roots, a controlled environment agriculture (CEA) startup, recently introduced a groundbreaking program supported by the Bill & Melinda Gates Foundation. The program aims to demonstrate the feasibility of removing light from commercial indoor vertical farming by utilizing gene-edited (CRISPR) plants that grow heterotrophically. These plants can add biomass through carbon uptake from acetate [...]

Nobel Prizes In Both Physics & Chemistry Involve Light & Quantum Mechanics

The Nobel Prizes awarded, this month, in both Chemistry and Physics had some things in common. Both involved scientific breakthroughs involving light, as well as distance scales so small that quantum mechanical behavior is essential to understand the science. Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov were awarded the Nobel Prize in [...]


Profound Relationship Discovered Between Light Polarization & Entanglement

  New research by Assistant Professor of Physics Xiao-Feng Qian, at the Stevens Institute of Technology has linked two separate fields of physics: Coherence Optics and Classical Mechanics. It introduces a universal relationship between the polarization of light and its entanglement properties. A new quantitative relationship between certain quantum properties of light are connected and [...]

British Scientists Discover Bright Lights Enable Low-Impact Scallop Fishing

  Scientists from Fishtek Marine, a manufacturer of sustainable fishing gear, had a surprise discovery. Bright lights that they added to crab pots to catch more crabs instead attracted loads of scallops. The scallops swam into the traps to get to the lights. Traditional scallop fishing involves dredging the bottom of the ocean, causing considerable [...]

Researchers Achieve 80+% Efficiency For Long-Distance Wireless Charging

Researchers at Aalto University in Finland have achieved a new milestone in wireless charging. Efficiency had always dropped dramatically as the distance between wireless power transmitter and receive increased. The Aalto researchers, however, achieved 80+% efficiency at a distance of 7” between the transmitter and receiver antennas. To do this, the team developed a new [...]
