Genes find their partners without matchmakers
A new study provides more evidence that identical sections of DNA can match up with each other without the help of other molecules.

Maternal intake of past-its-prime fish oil linked to newborn death, rat study finds
Nearly 30 percent of newborn pups born to pregnant rats fed highly-oxidized ("off") fish oil died within two days after birth, finds a new study.

A 'smart dress' for oil-degrading bacteria
The modified polyelectrolyte-magnetite nanocoating was applied to functionalize the cell walls of oil decomposing bacteria Alcanivorax borkumensis.

How the immune system might evolve to conquer HIV
Scientists have mathematically modeled the coevolutionary processes that describe how antibodies and viruses interact and adapt to one another over the course of a chronic infection, such as HIV/AIDS.

Biologists home in on paleo gut for clues to our evolutionary history
A new study of the gut microbiomes of humans, chimps, bonobos and gorillas shows that at least two major groups of bacteria have cospeciated with these hosts, with a lineage going back at least 15 million years to our last common ancestor. Researchers hope to reconstruct the ancestral 'paleo gut' that went with our paleo diet, and use the gut bacteria to track human migration.

New mechanism of tuberculosis infection
Researchers have identified a new way that tuberculosis bacteria get into the body, revealing a potential therapeutic angle to explore.

Scientists program cells to remember and respond to series of stimuli
Engineers have programmed cells to remember and respond to events. This approach to circuit design enables scientists to create complex cellular state machines and track cell histories.

Yeast emerges as hidden third partner in lichen symbiosis
For nearly 150 years, lichens have been the model organisms of symbiosis. Now researchers have uncovered an unexpected third partner embedded in the lichen cortex or 'skin' -- yeast.

3-D-printing lab instruments one block at a time
Building lab instruments for chemistry and biology experiments used to be an expensive, time consuming process only done by scientists with specialized training. A 3-D printed, Lego-like system of blocks is changing that. In addition to real research applications, the system can also be used for STEM education, where students gain both an engineering experience by building the instruments and a science experience as they use them.

Synthetic biology used to limit bacterial growth and coordinate drug release
Researchers have engineered a clinically relevant bacterium to produce cancer drugs and then self-destruct and release the drugs at the site of tumors. The approach enables continual production and release of drugs at disease sites in mice while simultaneously limiting the size, over time, of the populations of bacteria engineered to produce the drugs. The strategy represents the use of synthetic biology in therapeutics.
