Complex nerve-cell signaling traced back to common ancestor of humans and sea anemones
New research shows that a burst of evolutionary innovation in the genes responsible for electrical communication among nerve cells in our brains occurred over 600 million years ago in a common ancestor of ...
Nerve impulses can collide and continue unaffected
According to the traditional theory of nerves, two nerve impulses sent from opposite ends of a nerve annihilate when they collide. New research from the Niels Bohr Institute now shows that two colliding nerve ...
Bioelectronics could lead to a new class of medicine
Imagine having tiny electronics implanted somewhere in your body that can regulate nerve signals and make symptoms of various disorders go away. That's the vision of the field of bioelectronic medicine—the emerging discipline ...
Solitary acoustic waves observed to propagate at a lipid membrane interface
Horses set to gain health benefits from stem cell advance
Horses suffering from neurological conditions similar to those that affect humans could be helped by a breakthrough from stem cell scientists.
Made to order at the synapse: Dynamics of protein synthesis at neuron tip
Protein synthesis in the extensions of nerve cells, called dendrites, underlies long-term memory formation in the brain, among other functions. "Thousands of messenger RNAs reside in dendrites, yet the dynamics ...
Scientists model human disease in stem cells
Many scientists use animals to model human diseases. Mice can be obese or display symptoms of Parkinson's disease. Rats get Alzheimer's and diabetes.
Carbon nanotube harpoon catches individual brain-cell signals
Neuroscientists may soon be modern-day harpooners, snaring individual brain-cell signals instead of whales with tiny spears made of carbon nanotubes.
Blowfly protein key to terror poison antidote
A protein that costs the Australian sheep industry hundreds of millions of dollars each year may also pave the way to an antidote for chemical warfare agents.
Computer simulations reveal the energy landscape of ion channels
Every cell of our body is separated from its environment by a lipid bilayer. In order to maintain their biological function and to transduce signals, special proteins, so called ion channels, are embedded ...
Shedding light on the senses fish use for navigation
(Phys.org) —New research conducted at Queen's University has discovered that polarized light vision, which is used for navigation and orientation by rainbow trout, changes with age.
3-D printer builds synthetic tissues
A custom-built programmable 3D printer can create materials with several of the properties of living tissues, Oxford University scientists have demonstrated.
Lipid vesicles to replace mouse experiments
Researchers from ETH Zurich have filed a patent application for a method to test the biological activity of one of the strongest toxins known, the botulinum neurotoxin. If the procedure is adopted by the ...
New nanoparticle halts multiple sclerosis, now being tested in Type 1 diabetes and asthma
In a breakthrough for nanotechnology and multiple sclerosis, a biodegradable nanoparticle turns out to be the perfect vehicle to stealthily deliver an antigen that tricks the immune system into stopping its attack on myelin ...
