Evolutionary Arms “Chase”

ScreenShot2017-08-18at5.40.35PM.png

The study analyzed multiple species of Inga, a genus of tropical trees that produces defensive chemicals, and their various insect herbivores. The researchers found that closely-related plants evolved very different defensive traits. Additionally, their analysis revealed that herbivores may drive evolution of plant defenses, but may not show coevolutionary adaptations. Instead, they may ‘chase’ plants based on the herbivore’s own traits at the time they encounter a new host.

A new University of Utah-led study shows that targeted forest regeneration among the largest and closest forest fragments in the Eastern Arc Mountains of Tanzania and the Atlantic Forest of Brazil can dramatically reduce extinction rates of bird species over time.

University at Buffalo researchers have assembled a team of three antibiotics that, together, are capable of eradicating E. coli carrying mcr-1 and ndm-5 — genes that make the bacterium immune to last-resort antibiotics.

Can a group of three single-celled, algae-like organisms produce high quantities of sugar just right for making biofuels? Laboratory results indicate that they can. Sandia National Laboratories is helping Bay Area-based HelioBioSys understand whether these cyanobacteria can be grown large scale.

When Fish Swim in the Holodeck

Behavior experiments are useful tools to study brain function. Standard experiments to investigate behavior in popular lab animals such as fish, flies or mice however only incompletely mimic natural conditions. The understanding of behavior and brain function is thus limited. Virtual Reality (VR) helps in generating a more natural experimental environment but requires immobilization of the animal, disrupting sensorimotor experience and causing altered neuronal and behavioral responses. Researchers at the University of Freiburg, and the Max F. Perutz Laboratories (MFPL), a joint venture of the University of Vienna and the Medical University of Vienna, in collaboration with groups at the Research Institute of Molecular Pathology (IMP) and the MPI for Ornithology in Konstanz, have now developed a VR system for freely moving animals – FreemoVR – to overcome most of these limitations. Their findings are now published in Nature Methods.
