Now we know why old scizophrenia medicine works on antibiotics-resistant bacteria
|
|
|
An old medicine for schizophrenia is effective at treating something completely different than it was designed for: antibiotic-resistant bacteria. So far it has been a mystery how this old schizophrenia medicine works, but now researchers have figured it out. This can lead to a new medicine against the increasingly threatening antibiotic-resistant bacteria.

Developmental genetics of space and time
|
|
|
Scientists have conducted a study that reveals important and useful insights into how and why developmental genes often take inputs from two independent “morphogen concentration gradients.”

Untangling the tree of life
|
|
|
Phylogeneticists examined the reasons why large-scale tree-of-life studies are producing contradictory results and have proposed a suite of novel techniques to resolve the conflicts.

Cells must use their brakes moderately for effective speed control
|
|
|
How cells regulate their own function by “accelerating and braking” is important basic knowledge when new intelligent medicines are being developed, or when plant cells are tweaked to produce more bioenergy. Scientists now show a model of how cells’ regulatory systems work.

Same musicians play a brand new tune: Unusual interplay of signaling pathways shapes critical eye structure
|
|
|
A small ensemble of musicians can produce an infinite number of melodies, harmonies and rhythms. So too, do a handful of workhorse signaling pathways that interact to construct multiple structures that comprise the vertebrate body. In fact, crosstalk between two of those pathways -- those governed by proteins known as Notch and BMP (for Bone Morphogenetic Protein) receptors -- occurs over and over in processes as diverse as forming a tooth, sculpting a heart valve and building a brain.

Alligator stem cell study gives clues to tooth regeneration
|
|
|
Alligators may help scientists learn how to stimulate tooth regeneration in people, according to new research. For the first time, a global team of researchers has uncovered unique cellular and molecular mechanisms behind tooth renewal in American alligators.
