Maintaining large-scale satellite constellations using logistics approach

Posted: 12 Jul 2019 02:40 PM PDT

Researchers have identified a critical hidden challenge about replacing the broken satellites in megaconstellations and proposed a unique solution with inventory control methods.

Novel nanoparticles deliver CRISPR gene editing tools into the cell with much higher efficiency

Posted: 12 Jul 2019 12:19 PM PDT

Researchers have developed a significantly improved delivery mechanism for the CRISPR/Cas9 gene editing method in the liver. The delivery uses biodegradable synthetic lipid nanoparticles that carry the molecular editing tools into the cell to precisely alter the cells' genetic code with as much as 90 percent efficiency. The nanoparticles could help overcome technical hurdles to enable gene editing in a broad range of clinical therapeutic applications.

Automated system generates robotic parts for novel tasks

Posted: 12 Jul 2019 12:19 PM PDT

An automated system designs and 3D prints complex robotic parts called actuators that are optimized according to an enormous number of specifications. In short, the system does automatically what is virtually impossible for humans to do by hand.

Shifts to renewable energy can drive up energy poverty, study finds

Posted: 12 Jul 2019 12:19 PM PDT

Efforts to shift away from fossil fuels and replace oil and coal with renewable energy sources can help reduce carbon emissions but do so at the expense of increased inequality, according to a new study.

Device channels heat into light
