Genetic instructions from mom set the pattern for embryonic development
Fri, 15 Dec 2017 12:47:39 EST
A new study indicates an essential role for a maternally inherited gene in embryonic development. The study found that zebrafish that failed to inherit specific genetic instructions from mom developed fatal defects earlier in development, even if the fish could make their own version of the gene.

A new genetic analysis of fungal yeast infections (candidiasis) from around the world has revealed surprising secrets about how these microbes reproduce and cause disease, according to a new study.
Committed to relatives: Hounds and wolves share their parasites
Fri, 15 Dec 2017 10:51:54 EST
Grey wolves, as all wild animals, are hosts to a variety of parasites. The presence of grey wolves in German forests has little influence on the parasite burden of hunting dogs, according to a new study.
Nanoparticles as a solution against antibiotic resistance?
Fri, 15 Dec 2017 09:44:56 EST
Scientists have succeeded in developing an efficient method to treat mucoviscidosis. Crucial are nanoparticles that transport the antibiotics more efficiently to their destination. First of all, the active particles need to have a certain size to be able to reach the deeper airways and not to bounce off somewhere else before. Ultimately, they have to penetrate the thick layer of mucus on the airways as well as the lower layers of the bacteria biofilm.
First-of-its-kind chemical oscillator offers new level of molecular control
Thu, 14 Dec 2017 18:18:26 EST
Researchers successfully constructed a first-of-its-kind chemical oscillator that uses DNA components. DNA molecules that follow specific instructions could offer more precise molecular control of synthetic chemical systems, a discovery that opens the door for engineers to create molecular machines with new and complex behaviors.
