Molecular motors cooperate in moving cellular cargo, study shows
...." Dynein and kinesin are biomolecular motors that haul cargo from one part of a cell to another. Dynein moves material from the cell membrane to the nucleus; kinesin moves material from the cell nucleus to the cell membrane. The little cargo transporters accomplish their task by stepping along filaments ......attery for later use, greatly reducing the need to haul and use heavy replacement batteries. "The need for electronic devices in remote areas is an increasing reality these days," says Rome. "Throughout history, humans have solved many problems by inventing passive devices to enhance the movements made by...Seal rookeries could provide a reliable food source for endangered California condors, study finds
... the coast south of Big Sur where seals frequently haul out. "Free-flying condors are just not finding these areas yet so we need to encourage them to do so," he adds. Other major haul-outs can be found from Baja California to British Columbia. "If we can train condors to find sites along the beach where ...Hooked on fishing, and we're heading for the bottom, says scientist
...ere have been regional variations, the global fish haul has gradually sunk. "There's no doubt about this," says Dr. Pauly whose findings have been published in the world's leading peer-reviewed journals, including Science and Nature. "We're in a phase where increasing fishing effort produces less catch." ...Researchers discover botulism toxin's insidious route into nerve cells
...sicles are sac-like cargo carriers in neurons that haul neurotransmitters from the cell's interior to the synapses, which are the junctions between neurons. At the synapse, neurotransmitters are released, triggering nerve impulse in neighboring neurons. "Our uptake experiments with all the toxins showing ...NASA ice images aid study of Pacific walrus arctic habitats
...t-long, 3,000 pound mammals. In the spring, walrus haul out on this floating ice to rest, mate and rear their young. Recently, NASA collaborated with the Department of Interiors U.S. Fish and Wildlife Service (USFWS) in Alaska to determine the usefulness of satellite imagery for studying the effect of cli...CESAR could hail cheaper and greener small aircraft
...ncrease in coming years. "The view is that short haul flights within Europe will become more extensive as the Eastern European counties expand their trade with the West. "The grant we have received will allow us to employ two full-time researchers to carry out extensive research into how electromechan...MIT engineer works toward clean water, more
... the requirements of the local women who typically haul and store water, as well as being affordable to people earning one dollar a day. The same general principles also apply to other co-evolutionary design projects. Murcott is currently focusing her energies in the northern region of Ghana, thanks t......has been based on observations made when the seals haul out on sub Antarctic islands to breed, such as the number and physical condition of the animals, Professor Hindell said. In particular, we have had no way to study how the seals interact with their environment and the prey within it. By monitoring ...
