Engineer, physicist to turn the inner workings of living cells into 'molecular movies'
What happens when a chemical engineer and a physicist walk into a bar? They forge a collaboration that could change biological imaging.
Light workout: Scientists use optogenetics to effectively stimulate muscle movement in mice
Researchers at Stanford University were able to use light to induce normal patterns of muscle contraction, in a study involving bioengineered mice whose nerve-cell surfaces are coated with special light-sensitive proteins.
Hitchhiking nanotubes show how cells stir themselves
(Phys.org) —Chemical engineers from Rice University and biophysicists from Georg-August Universität Göttingen in Germany and the VU University Amsterdam in the Netherlands have successfully tracked single ...
Nano-machines for 'bionic proteins'
Physicists of the University of Vienna together with researchers from the University of Natural Resources and Life Sciences Vienna developed nano-machines which recreate principal activities of proteins. ...
Human arm sensors make robot smarter (w/ Video)
Using arm sensors that can "read" a person's muscle movements, Georgia Institute of Technology researchers have created a control system that makes robots more intelligent. The sensors send information to ...
How the tiny fruit fly could help science get to the heart of human genetics
(Phys.org) —A new study by scientists at the University of Sussex shows how the tiny fruit fly could be used to better understand the genetic processes at work in humans, such as those governing heart function.
Bats use blood to reshape tongue for feeding
Nectar-feeding bats and busy janitors have at least two things in common: They want to wipe up as much liquid as they can as fast as they can, and they have specific equipment for the job. A study in the Proceedings of th ...
The material that's like an octopus
(Phys.org)—The atomic structure of a zinc-based material has a surprising amount in common with the tentacles of an octopus, Oxford University researchers have found.
Soft autonomous robot inches along like an earthworm (w/ Video)
Earthworms creep along the ground by alternately squeezing and stretching muscles along the length of their bodies, inching forward with each wave of contractions. Snails and sea cucumbers also use this mechanism, ...
Biologists take snapshot of fleeting protein process
Structural biologists from Rice University and Baylor College of Medicine (BCM) have captured the first three-dimensional crystalline snapshot of a critical but fleeting process that takes place thousands ...
Cool muscles: Storing elastic energy for flight
(Phys.org) —Flying has always fascinated humans, probably because we are so relentlessly Earthbound. One of the things that interests researchers who study flight is the question of how animals that do ...
Single gene has major impact on gaits in horses and in mice
Researchers at Uppsala University, Swedish University of Agricultural Sciences and their international collaborators have discovered a mutation in a single gene in horses that is critical for the ability ...
