New method could reveal what genes we might have inherited from Neanderthals
Using neural networks, researchers from the University of Copenhagen 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 … [Read more...] about New method could reveal what genes we might have inherited from Neanderthals
Compact quantum computer for server centers: Researchers build smallest quantum computer yet based on industry standards
So far, quantum computers have been one-of-a-kind devices that fill entire laboratories. Now, physicists at the University of Innsbruck 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. Over the past three decades, fundamental groundwork for building … [Read more...] about Compact quantum computer for server centers: Researchers build smallest quantum computer yet based on industry standards
The Earth has a pulse — a 27.5-million-year cycle of geological activity, researchers say: Analysis of 260 million years of major geological events finds recurring clusters 27.5 million years apart
Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a "pulse," according to a new study published in the journal Geoscience Frontiers. "Many geologists believe that geological events are random over time. But our study provides statistical evidence for a common cycle, suggesting that these geologic events are correlated and not random," … [Read more...] about The Earth has a pulse — a 27.5-million-year cycle of geological activity, researchers say: Analysis of 260 million years of major geological events finds recurring clusters 27.5 million years apart
New cold atom source lays groundwork for portable quantum devices
Although quantum technology has proven valuable for highly precise timekeeping, making these technologies practical for use in a variety of environments is still a key challenge. In an important step toward portable quantum devices, researchers have developed a new high-flux and compact cold-atom source with low power consumption that can be a key component of many quantum … [Read more...] about New cold atom source lays groundwork for portable quantum devices
New method for molecular functionalization of surfaces
One vision that is currently driving material scientists is to combine organic molecules (and their diverse functionalities) with the technological possibilities offered by extremely sophisticated semiconductor electronics. Thanks to modern methods of micro- and nanotechnology, the latter designs ever more efficient electronic components for a wide variety of applications. … [Read more...] about New method for molecular functionalization of surfaces
Quantum computing: Common perovskite superfluoresces at high temperatures
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. The finding from North Carolina State University researchers also indicates that superfluorescence may be a common characteristic for this entire class of materials. Superfluorescence is an … [Read more...] about Quantum computing: Common perovskite superfluoresces at high temperatures
Modeling a circular economy for electronic waste: Engineers propose solutions for e-waste recycling fraud
Think about how many different pieces of technology the average household has purchased in the last decade. Phones, TVs, computers, tablets, and game consoles don't last forever, and repairing them is difficult and often as expensive as simply buying a replacement. Electronics are integral to modern society, but electronic waste (e-waste) presents a complex and growing … [Read more...] about Modeling a circular economy for electronic waste: Engineers propose solutions for e-waste recycling fraud
Microscopy deep learning predicts viral infections
In humans, adenoviruses can infect the cells of the respiratory tract, while herpes viruses can infect those of the skin and nervous system. In most cases, this does not lead to the production of new virus particles, as the viruses are suppressed by the immune system. However, adenoviruses and herpes viruses can cause persistent infections that the immune system is unable to … [Read more...] about Microscopy deep learning predicts viral infections
New software for designing sustainable cities
New technology could help cities around the world improve people's lives while saving billions of dollars. The free, open-source software developed by the Stanford Natural Capital Project creates maps to visualize the links between nature and human wellbeing. City planners and developers can use the software to visualize where investments in nature, such as parks and … [Read more...] about New software for designing sustainable cities
