Understanding the dangers of social engineering
Social engineering is a manipulative technique used by individuals or groups to deceive or manipulate others into divulging confidential or sensitive information, performing actions, or making decisions that are not in their best interest. It often i.....»»
These worms have rhythm: New imaging technique to observe active gene expression in real time
There's a rhythm to developing life. Growing from a tiny cell cluster into an adult organism takes precise timing and control. The right genes must turn on at the right time, for the right duration, and in the correct order. Losing the rhythm can lea.....»»
Experimental quantum imaging distillation with undetected light
It is possible to image an object with an induced coherence effect by making use of photon pairs to gain information on the item of interest—without detecting the light probing it. While one photon illuminates the object, its partner alone is detec.....»»
Photocoupled electroreduction of CO2 over photosensitizer decorated covalent organic frameworks
Electrocatalytic CO2 reduction reaction (CO2RR) is thought to be an ecologically favorable technique for using CO2 as a cheap and abundant C1 feedstock for the production of value-added chemicals such as CO. However, the thermodynamically stable natu.....»»
