The twain finally meet: Nanowires and nanotubes combined to form intracellular bioelectronic probes
Scientists create renewable fossil fuel alternative using bacteria
The development is a step towards commercial production of a source of fuel that could one day provide an alternative to fossil fuels.
Nano-scale gold particles are good candidates for drug delivery
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.
New technique allows "nanobiopsies" of living cells
(Phys.org) —Researchers at UC Santa Cruz have developed a robotic "nanobiopsy" system that can extract tiny samples from inside a living cell without killing it. The single-cell nanobiopsy technique is ...
The inheritance of the primary cilium and the soul of the cell
Spider venom reveals new secret
University of Arizona researchers led a team that has discovered that venom of spiders in the genus Loxosceles, which contains about 100 spider species including the brown recluse, produces a different chemic ...
Natural affinities—unrecognized until now—may have set stage for life to ignite
The chemical components crucial to the start of life on Earth may have primed and protected each other in never-before-realized ways, according to new research led by University of Washington scientists.
Architecture of a lipid transport protein revealed
For the first time, the complex architecture of a protein that controls the transport of lipids between the two layers of a cell membrane has been described. With this structure, Biochemists from the University ...
Cell division, minus the cells
(Phys.org) —The process of cell division is central to life. The last stage, when two daughter cells split from each other, has fascinated scientists since the dawn of cell biology in the Victorian era. ...
Water purification at the molecular level
(Phys.org) —Fracking for oil and gas is a dirty business. The process uses millions of gallons of water laced with chemicals and sand. Most of the contaminated water is trucked to treatment plants to be ...
How did complex life evolve? The answer could be inside out
A new idea about the origin of complex life turns current theories inside out. In the open access journal BMC Biology, cousins Buzz and David Baum explain their 'inside-out' theory of how eukaryotic cells, which all multic ...
Cell membranes self-assemble
A self-driven reaction can assemble phospholipid membranes like those that enclose cells, a team of chemists at the University of California, San Diego, reports in Angewandte Chemie.
Emergent behavior lets bubbles 'sense' environment
Tiny, soapy bubbles can reorganize their membranes to let material flow in and out in response to the surrounding environment, according to new work carried out in an international collaboration by biomedical ...
'Endless possibilities' for bio-nanotechnology
Scientists from the University of Leeds have taken a crucial step forward in bio-nanotechnology, a field that uses biology to develop new tools for science, technology and medicine.
