- A Bitcoin documentation pull-request (bitcoin/bitcoin.org#713) corrects the widespread but misleading claim that “51 % of miners can attack the network,” clarifying that control is measured by hashrate, not node count.  
- Microfluidic in-vitro fertilization now succeeds with far fewer and less-concentrated spermatozoa than conventional methods, demonstrating a path to low-volume, high-precision reproductive technology.  
- An optofluidic laser-microsurgery platform for oocytes (PMC3380719) enables automated, contact-free cell manipulation, while magnetic nanoparticles conjugated to signaling proteins provide remote, spatially controlled activation of ion channels and cytoskeletal re-organization—together forming a toolkit for “magnetic synthetic biology.”  
- Scaling rabbit-based polyclonal-antibody production involves 24–36 animals per batch, 12-week cull cycles, and ELISA-based affinity confirmation, but faces regulatory and market-entry barriers versus large commercial facilities; chicken antibodies were rejected because they do not bind Protein A/G, complicating downstream processing.  
- Robert A. Freitas Jr.’s 1979 monograph “Xenology” (xenology.info) is highlighted as the most comprehensive systematic study of extraterrestrial life, intelligence, and civilization yet produced.  
- ArXiv papers 1104.4362 and 0908.1803 explore the speculative physics of black-hole starships—microscopic black holes as compact, high-efficiency energy sources for relativistic probes with masses up to hundreds of thousands of tonnes—while a 2014 SciRP paper critiques standard general-relativity calculations for massive-body collapse to singular black holes.  
- X-ray pulsar-based spacecraft navigation uses compact, low-power detectors and the stable rotation of millisecond-period pulsars for 3-D position estimation, though “timing glitches” remain an engineering challenge.  
- NIH’s 3-D Print Exchange (3dprint.nih.gov) offers open-source biomedical hardware, including downloadable models for an NK-cell F-actin synapse and a 3-axis micromanipulator/CNC assembly, complementing grassroots efforts like an announced open-source CNC router build.
