Light-field control of real and virtual charge carriers

Posted by in categories: computing, materials

Year 2022 femtosecond logic gates for computers once thought to be almost a myth only for 2099 dreams is now real.


Light-field control of real and virtual charge carriers in a gold–graphene–gold heterostructure is demonstrated, and used to create a logic gate for application in lightwave electronics.

An organic jelly made fractal logic gate with an infinite truth table

Posted by in category: futurism

Year 2015 Once again nature shows intelligent design so advanced that it can leave us in awe. I personally never thought that an infinite logic gate was possible due to the nature of the speed of it or that it would create a gravity well or something weird but here it is an infinite logic gate 😗😁😘.


Scientific Reports — An organic jelly made fractal logic gate with an infinite truth table. Sci. Rep. 5, 11265; doi: 10.1038/srep11265 (2015).

Dynamic models of complete, day 14 human embryos grown from stem cells

Posted by in categories: biotech/medical, life extension

A research team headed by Professor Jacob Hanna at the Weizmann Institute of Science has created complete models of human embryos from stem cells cultured in the lab – and managed to grow them outside the uterus up to day 14. As reported today in Nature, these synthetic embryo models had all the structures and compartments characteristic of this stage, including the placenta, yolk sac, chorionic sac and other external tissues that ensure the models’ dynamic and adequate growth.

Longevity. Technology: Cellular aggregates derived from human stem cells in previous studies could not be considered genuinely accurate human embryo models, because they lacked nearly all the defining hallmarks of a post-implantation embryo. In particular, they failed to contain several cell types that are essential to the embryo’s development, such as those that form the placenta and the chorionic sac. In addition, they did not have the structural organization characteristic of the embryo and revealed no dynamic ability to progress to the next developmental stage.

Given their authentic complexity, the human embryo models obtained by Hanna’s group may not only provide an unprecedented opportunity to shed new light on the embryo’s mysterious beginnings, but open the door to new technologies for growing transplant tissues and organs.

How Does Your Body Turn Food Into Fuel? Scientists Tracked Individual Atoms to Find Out

Posted by in categories: food, particle physics

Inside our bodies at every moment, our cells are orchestrating a complex dance of atoms and molecules that uses energy to create, distribute and deploy the substances on which our lives depend.

And it’s not just in our bodies: all animals carry out this dance of metabolism, and it turns out none of them do it quite the same way.

In new research published in Science Advances, we analysed specific carbon atoms in amino acids – the building blocks of proteins – to discover distinctive fingerprints of the metabolism of different species.

BMW to use Amazon cloud technology to build its autonomous driving features for new EVs

Posted by in categories: robotics/AI, transportation

The German automaker’s next-generation advanced driver assistance system, or ADAS, will feature in its Neue Klasse range of electric cars that the company revealed on Saturday — that will launch in 2025.

It comes as traditional automakers look to boost the technology in their cars, with a particular focus on ADAS, to compete with Tesla.

“We’re not ‘gatekeepers,’” Apple and Microsoft tell European Union

Posted by in category: futurism

Companies would have to offer users alternatives to iMessage, Bing.

The legislation imposes new responsibilities on tech companies, including sharing data, linking to competitors, and making their services interoperable with rival apps.

Connected cars are a “privacy nightmare,” Mozilla Foundation says

Posted by in category: transportation

Data privacy protections are almost nonexistent when it comes to automobiles.

Mozilla looked at 25 car brands and found that all of them collected too much personal data, and from multiple sources—monitoring not just which buttons you push or what you do in any of the infotainment system’s apps but also data from other sources like satellite… More.


Today, the Mozilla Foundation published its analysis of how well automakers handle the privacy of data collected by their connected cars, and the results will be unlikely to surprise any regular reader of Ars Technica. The researchers were horrified by their findings, stating that “cars are the worst product category we have ever reviewed for privacy.”
