'Tricked' bacteria open new pathways to antimicrobial treatments
Scientists have developed a new technique to trick bacteria into revealing hundreds of holes in their cell walls, opening the door for drugs that destroy bacteria's cells.

Scientists are decoding the genetic mechanisms of aging
Scientists describes the mechanisms by which longevity is regulated post-transcriptionally, or after a genetic blueprint has been transcribed from an organism's DNA. The identification of these mechanisms will serve as a road map for screening new, more specific drugs to prolong healthy lifespan. The laboratory focuses on research on regeneration and aging.

Molecular biologists have pinpointed a gene that allows chlamydia to take up DNA from its host environment.
Read moreA Lego-like approach to improve nature's own ability to kill dangerous bacteria
A research team has demonstrated how it could improve upon the ability of nature's exquisitely selective collection of antimicrobial enzymes to attack bacteria in a way that's much less likely to cause bacterial resistance.
Read moreLongtime DNA mystery illuminated by buttons and flies
Biologists have uncovered an important clue in the longtime mystery of how long strands of DNA fold up to squeeze into microscopic cells, with each pair of chromosomes aligned to ensure perfect development.
Read morePlant death may reveal genetic mechanisms underlying cell self-destruction
Hybrid plants, which produced by crossing two different types of parents, often die in conditions in which both parents would survive. Certain hybrid tobacco plants, for example, thrive at 36 degrees Celsius, but die at 28 degrees Celsius, which is the temperature at which both parents would thrive. Researchers have begun to unravel the molecular mechanisms by which hybrid tobacco plant cells meet their demise.

Researchers have restored normal working memory to a mouse model of schizophrenia, eliminating a core symptom of the disorder that, in people, has proven virtually impossible to treat.

Scientists have developed CRISPR-BEST, a new genome editing tool for actinomycetes. It addresses the problem of genome instability caused by DNA double-stranded breaks in current CRISPR-technologies.
