Whole-Genome Sequencing Breaks the Cost Barrier
The ever-decreasing cost of sequencing is ushering in a new era in genomic medicine. Laura Bonetta reports on new studies that provide a glimpse of the opportunities ahead.
متن کاملAttosecond and Angstrom Science
When a strong laser field ionizes atoms (or molecules), the electron wave packet that tunnels from the molecule moves under the influence of the strong field and can re-collide with its parent ion. The maximum re-collision electron kinetic energy depends on the laser wavelength. Timed by the laser field oscillations, the re-colliding electron interferes with the bound state wave function from w...
متن کاملAngstrom-scale flatness using selective nanoscale etching
The realization of flat surfaces on the angstrom scale is required in advanced devices to avoid loss due to carrier (electron and/or photon) scattering. In this work, we have developed a new surface flattening method that involves near-field etching, where optical near-fields (ONFs) act to dissociate the molecules. ONFs selectively generated at the apex of protrusions on the surface selectively...
متن کاملNucleic acid nanotechnology-towards Angstrom-scale engineering.
Nucleic acids and analogues are suitable building blocks for reliable self-assembly of nanometer-sized two- or three-dimensional materials. In order to mimic or approach nature with respect to size and function, Angstrom-scale chemical engineering is emerging as pivotal for future developments. Efforts within nucleic acid nanotechnology will be focussed on generating rigid and stable low nanome...
متن کاملWhen it breaks , it breaks
Dependencies among software projects and libraries are an indicator of the often implicit collaboration among many developers in software ecosystems. Negotiating change can be tricky: changes to one module may cause ripple effects to many other modules that depend on it, yet insisting on only backwardcompatible changes may incur significant opportunity cost and stifle change. We argue that awar...
