How electric fish were able to evolve electric organs

Electric organs help electric fish, such as the electric eel, do all sorts of amazing things: They send and receive signals that are akin to bird songs, helping them to recognize other electric fish by species, sex and even ...

Only 10 vaquita porpoises survive, but species may not be doomed

The vaquita porpoise, the world's smallest marine mammal, is on the brink of extinction, with 10 or fewer still living in Mexico's Gulf of California, their sole habitat. But a genetic analysis by a team of UCLA biologists ...

Spider silk could stabilize cancer-suppressing protein

The p53 protein protects our cells from cancer and is an interesting target for cancer treatments. The problem is, however, that it breaks down rapidly in the cell. Researchers at Karolinska Institutet in Sweden have now ...

Model analyzes how viruses escape the immune system

One reason it's so difficult to produce effective vaccines against some viruses, including influenza and HIV, is that these viruses mutate very rapidly. This allows them to evade the antibodies generated by a particular vaccine, ...

New understanding of CRISPR-Cas9 tool could improve gene editing

Within a mere eight years, CRISPR-Cas9 has become the go-to genome editor for both basic research and gene therapy. But CRISPR-Cas9 also has spawned other potentially powerful DNA manipulation tools that could help fix genetic ...

Tracking inheritance of human mitochondrial DNA

New insight into how genetic information stored in human mitochondria is passed from one generation to the next could have important implications for genetic counseling of women planning pregnancies, according to a study ...
