Introduction Plants depend on light as their sole source of energy. Consequently, plants will achieve optimal fitness only if they are also able to coordinate their growth and metabolism with their light environment. To enable this coordination, plants have developed a series of photoreceptors that allow them to sense light from the UV-B to the near far-red. The red to near farred region of the...

The activation state of mTORC1, a master regulator of cell growth, is particularly sensitive to changes in the intracellular levels of the amino acid arginine, but the sensing mechanisms are poorly understood. In this issue of Cell, Chantranupong et al. identify CASTOR1 as a direct arginine sensor that acts through the GATOR2 complex to regulate mTORC1.

Ultrashort UV pulses at 258 nm with repetition rate of 10 kHz have been used to irradiate buffer solution of antibody. The tryptophan residues strongly absorb this radiation thus becoming capable to disrupt the disulfide bridges located next to them. Due to their high reactivity the opened bridges can anchor a gold plate more efficiently than other sites of the macromolecule giving rise to pref...

Structured light-based sensing (SLS) requires the illumination to be coded either spatially or temporally in the illuminated pattern. However, while the former demands the use of uniquely coded spatial windows whose size grows with the reconstruction resolution and thereby demanding increasing smoothness on the imaged scene, the latter demands the use of multiple image captures. This article pr...

Recent work in blind human subjects has confirmed the presence of a non-visual ocular photoreceptive mechanism similar to that described in blind mice. This system appears to subserve circadian photic entrainment, the pupillary light response, and a number of other aspects of neurophysiology and behavior.

The ever increasing demand for in situ monitoring of health, environment and security has created a need for reliable, miniaturised sensing devices. To achieve this, appropriate analytical devices are required that possess operating characteristics of reliability, low power consumption, low cost, autonomous operation capability and compatibility with wireless communications systems. The use of ...

Indirect sensing is a new sensing methodology which aims to eliminate the need need for special-purpose transducers in certain domains. Rather than the sensor signal being derived from a directly connected transducer, it is derived by data-mining representations of ambient phenomena (sound, light, temperature etc.) As an information-fusion task this involves the fusion of a knowledge source (i....
