Researchers from Rice University, Duke University, Brown University and Baylor College of Medicine developed magnetic technology to wirelessly control neural circuits in fruit flies. They used genetic engineering to express heat-sensitive ion channels in neurons that control behavior and iron nanoparticles to activate the channels. When the researchers activated the magnetic field in the fly cage, the nanoparticles converted the magnetic energy into heat, firing channels and activating neurons. An overhead camera filmed the fly during the experiment, and visual analysis showed the genetically modified fly assumed a wing-spreading posture about half a second after receiving the magnetic signal.

Robinson/Rice University A research team led by Rice University neuroscientists has created wireless technology to remotely activate certain brain circuits in fruit flies in less than a second. ...

Washington [US]July 10 (ANI): Researchers have definitively linked the function of a protein-specific domain important in plant microbial biology to cancer triggers in humans, knowledge that has eluded scientists for decades. The team’s findings, published in Nature Communications Biology, open new avenues for the development of selective drug therapies to fight different types of cancers such as cancers that start in the breast and stomach.

ORNL scientists set out to experimentally prove what they first concluded with computational studies: that the plasminogen-apple-nematode domain, or PAN, is associated with cell proliferation that promotes tumor growth in humans and defense signaling during plant-microbial interactions in bioenergetic plants. This association was first made when researchers were exploring the genomes of plants such as poplars and willows. In the latest study, the ORNL team demonst...
