Genes. Not important.
One of the great puzzles of evolutional biology is what induced certain living creatures to abandon solitary existence in favor of living in collaborative societies, as seen in the case of ants and other social, colony-forming insects. A major characteristic of so-called eusocial species is the division of labor between queens that lay eggs and…

Built from glass…
Ever wondered how groups of cells managed to build your tissues and organs while you were just an embryo? Using state-of-the-art techniques he developed, UC Santa Barbara researcher Otger Campàs and his group have cracked this longstanding mystery, revealing the astonishing innerworkings of how embryos are physically constructed. Cells coordinate by exchanging biochemical signals, but…

Eugenics works! So why not use it? A hard problem begging for a simple answer...
In a recent online discussion where the idea of modern eugenics was brought up, many people were against it. Since eugenics bring up correlations with the Nazis it is easy for most people to discard such ideas as wrong or unethical. It is obvious that applying eugenics is wrong. But all obvious things are very…

Father. Mother. Cosmos…
It was long thought that during an embryo's first cell division, one spindle is responsible for segregating the embryo's chromosomes into two cells. Scientists now show that there are actually two spindles, one for each set of parental chromosomes, meaning that the genetic information from each parent is kept apart throughout the first division. (1)…

Instability… Randomness… Out of design…
A study by researchers at the University of Illinois at Urbana-Champaign, the Massachusetts Institute of Technology, and the Applied Physics Laboratory, Johns Hopkins University has brought science one step closer to a molecular-level understanding of how patterns form in living tissue. The researchers engineered bacteria that, when incubated and grown, exhibited stochastic Turing patterns: a…
