Researchers discover anti-laser masquerading as perfect absorber
Researchers at Duke University have discovered that a perfect absorber of electromagnetic waves they described in a 2017 paper can easily be tweaked into a sort of "time-reversed laser" known as a coherent perfect absorber (CPA). The research appeared online on January 28 in the journal Advanced Optical Materials. A laser is a device that transforms energy into coherent light, meaning the light waves are…
Chemical data mining boosts search for new organic semiconductors
Producing traditional solar cells made of silicon is very energy intensive. On top of that, they are rigid and brittle. Organic semiconductor materials, on the other hand, are flexible and lightweight. They would be a promising alternative, if only their efficiency and stability were on par with traditional cells. Together with his team, Karsten Reuter, Professor of Theoretical Chemistry at the Technical University of Munich,…
Running an LED in reverse could cool future computers
In a finding that runs counter to a common assumption in physics, researchers at the University of Michigan ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away. The approach could lead to new solid-state cooling technology for future microprocessors, which will have so many transistors packed into a small space that current methods can't remove heat…
Sony α6400 mirrorless camera with the world’s fastest autofocus launches in the UAE
Sony's full-frame camera lineup boasts of some advanced imaging features which the company has brought down to its new α6400 E-mount mirrorless camera. The α6400 boasts of the world's fastest autofocus acquisition at 0.02 seconds but that's just one of the interesting things about this camera. With an AF acquisition speed of 0.02 seconds and 425 phase-detection and contrast- detection points spread across 84% of…
will.i.am speaks on security, AI, and new partnership with Majid Al Futtaim
At the World Government Summit 2019, Majid Al Futtaim announced a new partnership with I.AM+ to bring its voice-controlled AI to the Middle East for the first time. Named Omega, it’s designed to be a conversational, voice first, A.I platform. While similar to existing voice assistants such as Siri and Amazon Echo, Omega is able to understand more complex requests, as well as the context…

UMD researcher helps to crack the genetic code for wheat for...
The University of Maryland as part of the International Wheat Genome Sequencing Consortium (IWGSC) published findings in Science detailing the full genome sequence of wheat, the world's most widely cultivated crop. Additionally, a second companion paper was published in the same issue of Science with UMD as a major contributor in conjunction with the John Innes Centre, using this genome sequence to examine the way…
