The approach uses multiple radio frequencies to encode data, enabling multiple calculations to be carried out in parallel. The method shows promise for outperforming state-of-the-art electronic processors, with further enhancements possible.
Published The encounter between Neanderthals and Sapiens as told by their genomes



About 40,000 years ago, Neanderthals, who had lived for hundreds of thousands of years in the western part of the Eurasian continent, gave way to Homo sapiens, who had arrived from Africa. This replacement was not sudden, and the two species coexisted for a few millennia, resulting in the integration of Neanderthal DNA into the genome of Sapiens. Researchers have analyzed the distribution of the portion of DNA inherited from Neanderthals in the genomes of humans (Homo sapiens) over the last 40,000 years. These statistical analyses revealed subtle variations in time and geographical space.
Published How to build greener data centers? Scientists say crank up the heat



Colder is not always better for energy-hungry data centers, especially when it comes to their power bills. A new analysis says that keeping the centers at 41°C, or around 105°F, could save up to 56% in cooling costs worldwide. The study proposes new temperature guidelines that may help develop and manage more efficient data centers and IT servers in the future.
Published A non-exploitative economy favored the splendor of the Iberian Peninsula's Copper Age communities



A study describes the productive forces of the Chalcolithic communities of the southern half of the Iberian Peninsula as being very diverse, both in the type of tasks performed and in intensity, with a high degree of cooperation and no apparent signs of dependence between the different types of settlements or of political centralization. The work, based on the analysis of macrolithic tool data and the additional support of bioarchaeological information, allows to confirm the large ditched enclosure of Valencina de la Concepción (Seville) as a macro-populated area, inhabited by thousands of people, and not only as a place of worship.
Published Physicists demonstrate powerful physics phenomenon



In a new breakthrough, researchers have used a novel technique to confirm a previously undetected physics phenomenon that could be used to improve data storage in the next generation of computer devices.
Published Self-correcting quantum computers within reach?



Quantum computers promise to reach speeds and efficiencies impossible for even the fastest supercomputers of today. Yet the technology hasn't seen much scale-up and commercialization largely due to its inability to self-correct. Quantum computers, unlike classical ones, cannot correct errors by copying encoded data over and over. Scientists had to find another way. Now, a new paper illustrates a quantum computing platform's potential to solve the longstanding problem known as quantum error correction.

Published Birders and AI push bird conservation to the next level



Big data and artificial intelligence (AI) are being used to model hidden patterns in nature, not just for one bird species, but for entire ecological communities across continents. And the models follow each species’ full annual life cycle, from breeding to fall migration to non-breeding grounds, and back north again during spring migration.
Published AI drones to help farmers optimize vegetable yields



For reasons of food security and economic incentive, farmers continuously seek to maximize their marketable crop yields. As plants grow inconsistently, at the time of harvesting, there will inevitably be variations in quality and size of individual crops. Finding the optimal time to harvest is therefore a priority for farmers. A new approach making heavy use of drones and artificial intelligence demonstrably improves this estimation by carefully and accurately analyzing individual crops to assess their likely growth characteristics.
