0.75 Gbit/s key distribution with mode-shift keying chaos synchronization

Researchers propose a novel key distribution scheme based on mode-shift keying chaos synchronization to overcome limitations of laser transition time, achieving 0.7503 Gbit/s rate with high security. The method uses Fabry-Perot lasers and random drive source to generate chaotic waveforms, which are then quantized to produce random bits.

How SNPs can be used to detect disease pathways

Researchers developed VarSAn, a computational tool that analyzes SNPs to predict disease pathways, including breast and prostate cancer. The tool uses network analysis to identify perturbed pathways, offering a new approach to understanding genetic variation.

The earlier, the better

A team of researchers from FAU has investigated the timing of treatment in autoimmune diseases and found that early intervention can have a major impact on disease progression. By targeting B cells, which produce autoantibodies and influence other immune cells, researchers were able to prevent or delay severe organ damage.

Male giraffes are more socially connected than females

A new study reveals that male giraffes have higher social connectedness than females, with males forming more acquaintances and older males having shorter social paths. This complexity could impact conservation efforts for endangered giraffes.

Late Pleistocene humans may have hatched and raised cassowary chicks

An international team of scientists suggests that early humans in New Guinea collected cassowary eggs near maturity and then raised the birds to adulthood, with evidence supporting this behavior dating back 18,000 years. The researchers used eggshells to determine the developmental stage of ancient embryos/chicks when the eggs cracked.
