Companies today face incredible challenges around compliance, security and analytics, as their data lakes fill with invaluable information from ever more sensors. And tomorrow?s challenges will be no easier. As the digital age expands to cover all facets of our lives, more and more computing power will be necessary to process all of the data created.
It?s taken some time, but Microsoft?s $26 billion purchase of LinkedIn is finally starting to show some interesting results, with LinkedIn data starting to show up in tools like Outlook. It?s the first sign of Microsoft using the social network?s relationship graph, the complex data set that was the reason for one of Microsoft?s biggest Silicon Valley acquisitions.
In the last couple of years I have reviewed four of the leading business intelligence (BI) products: Tableau, Qlik Sense, Microsoft Power BI, and Amazon QuickSight. In general terms, Tableau sets the bar for ease of use, and Power BI sets the bar for low price.
This tiny motion-sensing strip contains 6 bright LEDs, and sticks anywhere. Just the trick for illuminating an entryway door-lock, a kitchen cabinet, drawers, closet or the glove box in your car. This deal gets you a 2-pack for 43% off.
This week?s articles describe a mechanism by which starvation primes a cellular nutrient-sensing system for activation upon refeeding; microRNAs that control pain sensitivity; and the lasting effects of early life stress on the likelihood of developing depression.
This week?s articles explore the structural basis for nitrate sensing in bacteria, the importance of attenuating healing responses to reduce fibrosis and allergy, and the recruitment of chromatin silencing factors in X chromosome inactivation.
Escherichia coli use a transmembrane sensor protein to sense nitrate in their external environment and initiate a biochemical response. Gushchin et al. compared crystal structures of portions of the NarQ receptor that included the transmembrane helices in ligand-bound or unbound
The quantum properties of the nitrogen vacancy (NV) defect in diamond can be used as an atomic compass needle that is sensitive to tiny variations in magnetic field. Schmitt et al. and Boss et al. successfully enhanced this sensitivity by several orders of magnitude (see the Perspective by Jordan). They applied a sequence of pulses to the NV center, the timing of which was set by and compared with a highly stable oscillator. This allowed them to measure the frequency of an oscillating magnetic field (megahertz bandwidth) with submillihertz resolution. Such enhanced precision measurement could be applied, for example, to improve nuclear magnetic resonance-based imaging protocols of single molecules.

In comparison to that of other animals, the human sense of smell is widely considered to be weak and underdeveloped. This is, however, an unproven hypothesis. In a Review, McGann traces the origins of this false belief back to comparative 19th-century neuroanatomical studies by Broca. A modern look at the human olfactory bulb shows that it is rather large compared with those of rats and mice, which are presumed to possess a superior sense of smell. In fact, the number of olfactory bulb neurons across 24 mammalian species is comparatively similar, with humans in the middle of the pack, and our sense of smell is similar to that of other mammals.

Transistors with exfoliated two-dimensional (2D) materials on a SiO2/Si substrate have been applied and have been proven effective in a wide range of applications, such as circuits, memory, photodetectors, gas sensors, optical modulators, valleytronics, and spintronics. However, these devices usually suffer from limited gate control because of the thick SiO2 gate dielectric and the lack of reliable transfer method. We introduce a new back-gate transistor scheme fabricated on a novel Al2O3/ITO (indium tin oxide)/SiO2/Si ?stack? substrate, which was engineered with distinguishable optical identification of exfoliated 2D materials. High-quality exfoliated 2D materials could be easily obtained and recognized on this stack. Two typical 2D materials, MoS2 and ReS2, were implemented to demonstrate the enhancement of gate controllability. Both transistors show excellent electrical characteristics, including steep subthreshold swing (62 mV dec?1 for MoS2 and 83 mV dec?1 for ReS2), high mobility (61.79 cm2 V?1 s?1 for MoS2 and 7.32 cm2 V?1 s?1 for ReS2), large on/off ratio (~107), and reasonable working gate bias (below 3 V). Moreover, MoS2 and ReS2 photodetectors fabricated on the basis of the scheme have impressively leading photoresponsivities of 4000 and 760 A W?1 in the depletion area, respectively, and both have exceeded 106 A W?1 in the accumulation area, which is the best ever obtained. This opens up a suite of applications of this novel platform in 2D materials research with increasing needs of enhanced gate control.
