The twain finally meet: Nanowires and nanotubes combined to form intracellular bioelectronic probes
Life 'not as we know it' possible on Saturn's moon Titan
A new type of methane-based, oxygen-free life form that can metabolize and reproduce similar to life on Earth has been modeled by a team of Cornell University researchers.
Protons fuel graphene prospects
Graphene, impermeable to all gases and liquids, can easily allow protons to pass through it, University of Manchester researchers have found.
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.
Researchers bring clean energy a step closer
For nearly half a century, scientists have been trying to replace precious metal catalysts in fuel cells. Now, for the first time, researchers at Case Western Reserve University have shown that an inexpensive metal-free catalyst ...
Voltage tester for beating cardiac cells
For the first time, scientists have succeeded in recording the current in membrane channels of contracting cardiac cells. To do this, the scientists combined an atomic force microscope with a widely used ...
Biochemist sheds light on structure of key cellular 'gatekeeper'
Facing a challenge akin to solving a 1,000-piece jigsaw puzzle while blindfolded—and without touching the pieces—many structural biochemists thought it would be impossible to determine the atomic structure ...
Engineers put the 'squeeze' on human stem cells
After using optical tweezers to squeeze a tiny bead attached to the outside of a human stem cell, researchers now know how mechanical forces can trigger a key signaling pathway in the cells.
Neutron beams reveal how two potential pieces of Parkinson's puzzle fit
To understand diseases like Parkinson's, the tiniest of puzzles may hold big answers. That's why a team including scientists from the National Institute of Standards and Technology (NIST) have determined ...
