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 ...
Scientists prove X-ray laser can solve protein structures from scratch
A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.
Super-thin membranes clear the way for chip-sized pumps
The ability to shrink laboratory-scale processes to automated chip-sized systems would revolutionize biotechnology and medicine. For example, inexpensive and highly portable devices that process blood samples ...
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 ...
Computer simulations reveal universal increase in electrical conductivity
Computer simulations have revealed how the electrical conductivity of many materials increases with a strong electrical field in a universal way. This development could have significant implications for practical ...
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.
Escherichia coli bacteria produce diesel on demand
It sounds like science fiction but a team from the University of Exeter, with support from Shell, has developed a method to make bacteria produce diesel on demand. While the technology still faces many significant ...
Biomimetic nanosponges absorb toxins released by bacterial infections and venom
Engineers at the University of California, San Diego have invented a "nanosponge" capable of safely removing a broad class of dangerous toxins from the bloodstream – including toxins produced by MRSA, E. co ...
Breakthrough in race to create 'bio-batteries'
(Phys.org) —Scientists at the University of East Anglia have made an important breakthrough in the quest to generate clean electricity from bacteria.
Computer simulations yield clues to how cells interact with surroundings
(Phys.org) —Your cells are social butterflies. They constantly interact with their surroundings, taking in cues on when to divide and where to anchor themselves, among other critical tasks.
Math model reveals insight into how first life forms were 'born'
An international team of physicists have revealed insights into how the very first life-forms made the jump from the non-living to the living world, by mathematically modelling biological states using energy waves called ...
Unearthing key function of plant hormone
Plants, like animals, employ hormones as messengers, which coordinate growth and regulate how they react to the environment. One of these plant hormones, auxin, regulates nearly all aspects of plant behavior and development, ...
Nanoscale freezing leads to better imaging
It's an odd twist. For scientists to determine if a cell is functioning properly, they must destroy it.
