# Key Points from #hplusroadmap Discussion

• Participants explored space technology concepts involving satellites transferring momentum onto pellets to slow satellites to Earth's speed for potential use as tethers, though concerns were raised about pellets surviving atmospheric transit.

• The discussion covered magnetism fundamentals, ranging from basic explanations of atoms as tiny electromagnets that align to form fields to more advanced concepts involving virtual photons and field theory.

• Technical conversation examined how magnetic fields could theoretically enable devices to bounce pellets back and forth without energy loss unless momentum transfers to the devices themselves.

• Detailed analysis of Terminal deoxynucleotidyl Transferase (TdT) highlighted its potential for template-free DNA synthesis in synthetic biology applications, with specific mutations like R387K that could enhance its activity.

• Research on TdT indicated it naturally polymerizes approximately 50 nucleotides and is regulated by TdT interacting factors (TdiFs) that can increase or decrease its activity by roughly 4-fold or 2-fold respectively.

• Ocean microbial ecology data revealed remarkable statistics: approximately 10^27 bacterial cells exist in oceans (10^6 cells per ml), while viruses number around 10^30 globally, outnumbering cellular life by a factor of 10.

• A significant claim that viruses kill approximately 40% of ocean bacteria daily was discussed, raising questions about microbial turnover rates and whether this process might actually increase overall biomass by releasing carbon and nutrients.
