Modeling a circular economy for electronic waste

Posted: 21 Jun 2021 02:41 PM PDT

New research develops a framework to understand the choices an electronic waste recycler has to make and the role that digital fraud prevention could have in preventing dishonest recycling practices.

Quantum computing: Common perovskite superfluoresces at high temperatures

Posted: 21 Jun 2021 01:05 PM PDT

A commonly studied perovskite can superfluoresce at temperatures that are practical to achieve and at timescales long enough to make it potentially useful in quantum computing applications.

New method for molecular functionalization of surfaces

Posted: 21 Jun 2021 01:05 PM PDT

An interdisciplinary team of researchers has succeeded in depositing nitrogen-containing organic molecules as a highly ordered layer on silicon. This opens up new perspectives for the development of more powerful semiconductor materials, which can be used, for example, in computers, photovoltaics or sensor technology.

New cold atom source lays groundwork for portable quantum devices

Researchers demonstrate a new high-flux and compact cold-atom source with low power consumption that can be a key component of many quantum technologies.

Microscopy deep learning predicts viral infections

Posted: 21 Jun 2021 09:37 AM PDT

When viruses infect cells, changes in the cell nucleus occur, and these can be observed through fluorescence microscopy. Using fluorescence images from live cells, researchers have trained an artificial neural network to reliably recognize cells that are infected by adenoviruses or herpes viruses. The procedure also identifies severe acute infections at an early stage.

New software for designing sustainable cities

Posted: 21 Jun 2021 05:40 AM PDT

By 2050, more than 70% of the world's population will live in cities. Researchers have developed software that shows city planners where to invest in nature to improve people's lives and save billions of dollars.

The Earth has a pulse -- a 27.5-million-year cycle of geological activity, researchers say

Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a 'pulse,' according to a new study.

Compact quantum computer for server centers

Posted: 18 Jun 2021 06:17 AM PDT

Quantum computers have been one-of-a-kind devices that fill entire laboratories. Now, physicists have built a prototype of an ion trap quantum computer that can be used in industry. It fits into two 19-inch server racks like those found in data centers throughout the world. The compact, self-sustained device demonstrates how this technology will soon be more accessible.

New method could reveal what genes we might have inherited from Neanderthals

Posted: 17 Jun 2021 08:55 AM PDT

Using neural networks, researchers have developed a new method to search the human genome for beneficial mutations from Neanderthals and other archaic humans. These humans are known to have interbred with modern humans, but the overall fate of the genetic material inherited from them is still largely unknown. Among others, the researchers found previously unreported mutations involved in core pathways in metabolism, blood-related diseases and immunity.
