Luv this as long as it doesn’t pollute space.
Space seeds could bring high-bandwidth Internet connectivity to the globe at less expense than the cost of putting one satellite into space.

Improving energy efficiencies — nice.
The remarkable properties researchers at the Australian National University (ARC Centre of Excellence CUDOS) and the University of California Berkeley have discovered in a new nano-metamaterial could lead to highly efficient thermophotovoltaic cells. The new artificial material glows in an unusual way when headed.
As shown in the image, the metamaterial comprises 20 stacked alternating layers of 30-nm-thick gold and 45-nm-thick magnesium fluoride dielectric, perforated with 260 × 530 nm holes that are arranged into a 750 × 750 nm square lattice.

Nice!
Our skin is our largest organ. A gateway between our brain and the rest of the world.
Imagine then a scene where skin could communicate what’s going on inside a human body. It could inform surgeons, provide alerts when our body is about to fall ill, or even diagnose diseases inside another human being, simply through the sense of touch.
The next time that you decide to run barefoot in the rain, etc. there is a health benefit that you’re receiving in the form of enhancing your brain.
FRIDAY, May 13, 2016 (HealthDay News) — Runners who want to boost their brain function should consider taking their running shoes off, new research suggests.
The study found that after running barefoot, participants saw improvements in working memory, or the ability to recall or process information. Running in shoes, however, didn’t result in the same advantage, researchers said.

Theoretical chemists at Princeton University have pioneered a strategy for modeling quantum friction, or how a particle’s environment drags on it, a vexing problem in quantum mechanics since the birth of the field. The study was published in the Journal of Physical Chemistry Letters (“Wigner–Lindblad Equations for Quantum Friction”). “It was truly a most challenging research project in terms of technical details and the need to draw upon new ideas,” said Denys Bondar, a research scholar in the Rabitz lab and corresponding author on the work.
Researchers construct a quantum counterpart of classical friction, a velocity-dependent force acting against the direction of motion. In particular, a translationary invariant Lindblad equation is derived satisfying the appropriate dynamical relations for the coordinate and momentum (i.e., the Ehrenfest equations). Numerical simulations establish that the model approximately equilibrates. (© ACS)

So, the US Military has developed a way to eliminate bad memories/ PTSD and another method to restore memories. Wish the US Government would make their minds up on this one — LOL.
A scientist in DARPA’s biological technologies offices explains how the agency is developing implants that could bring back memories.
US Government may have discovered a new method of safely getting rid of old chemical and other old stockpile weapons.
Getting rid of chemical weapons is one of the military’s most unpleasant duties. But in the future, it may be no more difficult than incinerating garbage, thanks to a team of DARPA-funded scientists who think they can turn some of the world’s deadliest poisons into harmless dirt.
Chemical weapons, including nerve agents and mustards, have been banned under international law since the 1990s, but many countries still harbor large stockpiles. In 2013, a horrific chemical weapons attack in Syria—called the Ghouta attack —claimed hundreds of civilian lives, prompting the international community to intervene and eliminate the country’s chemical weapons reserves. By August 2014, 600 metric tons of deadly weapons had been destroyed (in the military parlance, “demilitarized”) aboard the US Navy vessel MV Cape Ray.

Excellent read about future Commerce in Space — could we see an Amazon or a HomeDepot in space?
In space there are no service stations to pull into and get replacement parts for your satellite. Nor is there a towing service if a satellite is in the wrong orbit, a construction contractor to help you build structures, or a “Space Depot” for those who wish to “do-it-themselves” on orbit. In other words, we still operate within a first-generation space industrial enterprise, i.e. all commerce is on Earth, and we only focus on bits (data) coming from monolithic things that go up (i.e., satellites), which eventually die or just come down with no chance of repair or reuse.
Today the commercial space industry focuses exclusively on applications that support launching science, exploration, military, or established earth-bound data communication or delivery services, focusing data to/from space. The lack of technology to support or “markets” to enter has resulted in nebulous, unconsolidated and without-a-critical-mass investment in space-based infrastructure, industrialization, space resources (survey and process maturation) and global utility creation and delivery applications in space. However, all that may finally be changing.
