【推荐2】The “junk DNA” may be useful in developing future cancer treatments, according to a new report in the journal Nature Immunology. The discovery was led by Wilmot Cancer Institute investigators and University of Rochester biologists Vera Gorbunova, Ph.D., and Andrei Seluanov, Ph.D..

The DNA elements under research are known as retrotransposons (逆转录转座子). The bad side of them is that if left to run amok, they can give rise to tumors (肿瘤).

【推荐2】Anyone who commutes by car knows that traffic jams are an unavoidable part of life. But humans are not alone in facing potential backups.

Ants also commute — between their nest and sources of food. The survival of their habitats depends on doing this efficiently.

When humans commute, there’s a point at which cars become dense enough to slow down the flow of traffic, causing jam. Researchers wanted to know if ants on the move could also get stuck. So they regulated traffic density by constructing bridges of various widths between a colony of Argentine ants and a source of food. Then they waited and watched, trying to find out at what point they are going to have a traffic jam.
