Researchers investigate quantum network solutions, by ground and by air

While quantum computers represent a revolution in computation, they can't communicate with each other the way regular computers can—over the internet. If quantum computers could be connected through a quantum network, they could facilitate perfectly secure communication between more than two parties or combine computing power to solve much harder problems than one quantum computer could do...

New shape memory alloy discovered through artificial intelligence framework

Researchers from the Department of Materials Science and Engineering at Texas A&M University have used an Artificial Intelligence Materials Selection framework (AIMS) to discover a new shape memory alloy. The shape memory alloy showed the highest efficiency during operation achieved thus far for nickel-titanium-based materials. In addition, their data-driven framework offers proof of concept for...

Cell division in moss and animals more similar than previously thought

For a new plant to grow from a seed, cells need to divide numerous times. Daughter cells can each take on different tasks and sometimes vary in size. How plants determine the plane of cell division in this process, known as mitosis, is currently being researched. Working with Physcomitrella -- a moss plant, they have now identified how the mitotic apparatus is localized in the plant cell: "Using...

A surging glow in a distant galaxy could change the way we look at black holes

Something strange is afoot in the galaxy known as 1ES 1927+654: In late 2017, and for reasons that scientists couldn't explain, the supermassive black hole sitting at the heart of this galaxy underwent a massive identity crisis. Over a span of months, the already-bright object, which is so luminous that it belongs to a class of black holes known as active galactic nuclei (AGN), suddenly grew a lot...

How our brains influence language change

Our language is changing constantly. Researchers of the University of Vienna found that, over centuries, frequently occurring speech sound patterns get even more frequent. The reason for this development is that our brain can perceive, process and learn frequent, and thus prototypical sound patterns more easily than less frequent ones. The results of the study were published in the journal...

Misperceptions can threaten scientific advancement

Misperceptions of marginalized and disadvantaged communities' level of concern regarding COVID-19, as well as other issues such as climate change, constitutes a form of social misinformation that may undermine cooperation and trust needed to address collective problems, according to new Cornell-led research.

Single photon emitter takes a step closer to quantum tech

To get closer to quantum technology we need to develop non-classical light sources that can emit a single photon at a time and do so on demand. Scientists at EPFL have now designed one of these "single photon emitters" that can work at room temperature and is based on quantum dots grown on cost-effective silicon substrates.
