A study involving virtual rather than real patients was as effective as traditional clinical trials in evaluating a medical device used to treat brain aneurysms, according to new research. The findings are proof of concept for what are called in-silico trials, where instead of recruiting people to a real-life clinical trial, researchers build digital simulations of patient … [Read more...] about Using virtual populations for clinical trials

Rare-earth elements are in many everyday products, such as smart phones, LED lights and batteries. However, only a few locations have large enough deposits worth mining, resulting in global supply chain tensions. So, there's a push toward recycling them from non-traditional sources, such as waste from burning coal -- fly ash. Now, researchers in ACS' Environmental Science & … [Read more...] about Mining precious rare-earth elements from coal fly ash with a reusable ionic liquid

Augmented reality (AR) is poised to revolutionise the way people complete essential everyday tasks, yet older adults -- who have much to gain from the technology -- will be excluded from using it unless more thought goes into designing software that makes sense to them. The danger of older adults falling through the gaps has been highlighted by research carried out by … [Read more...] about AR can improve the lives of older adults, so why are apps designed mainly for youngsters?

A research team led by Professor Jang-Sik Lee of Pohang University of Science and Technology (POSTECH) has successfully developed an halide perovskite-based memory with an ultra-fast switching speed. The findings from this study were published in Nature Communications on June 10, 2021. Resistive switching memory is a promising contender for next-generation memory device due to … [Read more...] about Perovskite memory devices with ultra-fast switching speed

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

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

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

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
