To navigate the world, we all shimmy like these electric fish      (via sciencedaily.com)     Original source 

An electric knifefish shimmies in the water for the same reason a dog sniffs or a human glances around a new place -- to make sense of their surroundings. For the first time, scientists demonstrate that a wide range of organisms, even microbes, perform the same pattern of movements in order to sense the world.

Defect in fruit fly respiratory system may provide insights into human aortic aneurysms      (via sciencedaily.com)     Original source 

A team of researchers has gained new insights into the respiratory system of fruit flies -- the so-called tracheal system -- which could be important for future research into aneurysms. Scientists carried out genetic, cell biological and biochemical studies on Drosophila embryos. They found that the cells in the fruit fly's tracheal system are connected to the extracellular matrix by the proteins Dumpy and Piopio.

What do new moms and roaches have in common?      (via sciencedaily.com)     Original source 

Researchers are studying the dramatic physical transformation that some insects undergo to give birth to live young. This includes suppressing their immune systems to accommodate babies, which is something some insects and people have in common. Understanding how these systems work can help improve treatments for fibromyalgia and other immune disorders. An international team of researchers has examined the complex structural and physiological changes that take place in Hawaii's beetle-mimic cockroaches, which give birth to live young.

Restoring the function of a human cell surface protein in yeast cells      (via sciencedaily.com)     Original source 

Yeast cells are widely used to study G protein-coupled receptors (GPCRs), a large group of cell surface proteins in humans. However, several of these proteins lose their function when introduced into yeast cells. To tackle this issue, researchers developed an innovative strategy to restore GPCR function in yeast cells by inducing random mutations. Their findings can help understand GPCRs better and could pave the way to therapeutic breakthroughs for many diseases.

New insights into the genetics of the common octopus: Genome at the chromosome level decoded      (via sciencedaily.com)     Original source 

Octopuses are fascinating animals -- and serve as important model organisms in neuroscience, cognition research and developmental biology. To gain a deeper understanding of their biology and evolutionary history, validated data on the composition of their genome is needed, which has been lacking until now. Scientists have now been able to close this gap and, in a new study, determined impressive figures: 2.8 billion base pairs -- organized in 30 chromosomes. What sounds so simple is the result of complex, computer-assisted genome analyses and comparisons with the genomes of other cephalopod species.
