Breakthroughs in acoustic tracking shine new light on the lives of fish
...others to evaluate trade-offs of different reserve sizes and locations. "On land, scientists know where elk or bears roam, what their daily habits are, how far they go from home, but until recently we haven't had the tools to study daily movements of marine fishes," says Richard Starr of the University of...Nanoparticle probes are destined for major new role in medical diagnostics and drug delivery
...tiplexing, bioconjugated quantum dots of different sizes can be embedded in tiny polymer beads and finely tuned to tag a multitude of proteins or genetic sequences. In particular, says Dr. Nie, medical applications for namoparticles will focus on cancer, cardiovascular disease, and neurodegenerative disea...Powerful machines are coming in small packages
...ese operations can require integrating the feature sizes across seven or eight orders of magnitude. (By comparison, assembling a jet airplane using centimeter-sized rivets involves three orders of magnitude.) Some of the technologies Paul is working on include micromachined gas-liquid contactor membranes f...Insights gained from molecular modeling may lead to better insecticides
.... As a result, toxins of many different shapes and sizes can enter and be detoxified. Since the toxins are not as rigidly restricted, they are not detoxified quite as efficiently as some of the toxins encountered by the specialist P450.

...s. The scientists then looked at the relative sizes of cadherins and the integrins. One particular cadherin protein, cadherin 23, appeared to be the right size. Combined with the fact that mutations in the cadherin 23 gene are associated with deafness and deaf-blindness, it became the prime suspect in...Understanding nutrition labels can lead to healthier eating

Comparing the range of these step sizes to the physical dimensions of Condensin complexes, the authors were able to make some informed proposals for how Condensins interact with DNA for example, by forming large DNA loops that can be popped open by increased stretching force.
