Byproducts of ‘Junk DNA’ Implicated in Cancer Spread

The more scientists explore so-called “junk” DNA, the less the label seems to fit. Only an estimated two percent of the human genome encodes for functional proteins that carry out normal biological processes. The remaining approximately 98 percent—the “junk DNA”—has for many years been considered a useless artifact. Some junk […]

Lessons from flies: genetic diversity impacts disease severity

New research offers clues as to why some diseases are highly variable between individuals. The phenomenon is apparent in people with retinitis pigmentosa, a condition that causes the light-sensing cells in the eye to degenerate. While some only develop night blindness, others completely lose their sight, even when their condition […]

Double time limit for embryo research to further research into IVF, synthetic embryos and gene editing

In countries which already permit embryo research, there are no “compelling moral arguments” why the time limit for experimentation should not be doubled say ethics experts. Currently, research on embryos is limited in many countries to a maximum period of 14 days after their fertilisation in the lab. But ethicists […]
