Published Rock, paper, scissors: Searching for stronger nonlocality using quantum computers



In the quantum world particles can instantaneously know about each other's state, even when separated by large distances. This is known as nonlocality. Now, A research group has produced some interesting findings on the Hardy nonlocality that have important ramifications for understanding quantum mechanics and its potential applications in communications.
Published Long-distance quantum teleportation enabled by multiplexed quantum memories



Researchers report having achieved quantum teleportation from a photon to a solid-state qubit over a distance of 1km, with a novel approach using multiplexed quantum memories.
Published Nullarbor rocks reveal Australia's transformation from lush to dust



Researchers have discovered how long ago the Australian Nullarbor plain dried out, with a new approach shedding light on how ancient climate change altered some of the driest regions of our planet.
Published Team designs four-legged robotic system that can walk a balance beam



Researchers have designed a system that makes an off-the-shelf quadruped robot nimble enough to walk a narrow balance beam -- a feat that is likely the first of its kind.
Published Ancient DNA reveals the multiethnic structure of Mongolia's first nomadic empire



The Xiongnu, contemporaries of Rome and Egypt, built their nomadic empire on the Mongolian steppe 2,000 years ago, emerging as Imperial China's greatest rival and even inspiring the construction of China's Great Wall. In a new study, researchers find that the Xiongnu were a multiethnic empire, with high genetic diversity found across the empire and even within individual extended elite families. At the fringes of the empire, women held the highest positions of power, and the highest genetic diversity was found among low-status male servants, giving clues to the process of empire building that gave rise to Asia's first nomadic imperial power.
Published Processing data at the speed of light



Scientists have developed an extremely small and fast nano-excitonic transistor.
Published Dairy foods helped ancient Tibetans thrive in one of Earth's most inhospitable environments



The question of how prehistoric populations obtained sustainable food in the barren heights of the Tibetan Plateau has long attracted academic and popular interest. A new study highlights the critical role of dairy pastoralism in opening the plateau up to widespread, long-term human habitation.
Published It's all in the wrist: Energy-efficient robot hand learns how not to drop the ball



Researchers have designed a low-cost, energy-efficient robotic hand that can grasp a range of objects -- and not drop them -- using just the movement of its wrist and the feeling in its 'skin'.
Published Study re-evaluates hazards and climate impacts of massive underwater volcanic eruptions



Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new research.
Published Table tennis brain teaser: Playing against robots makes our brains work harder



Brain scans taken during table tennis reveal differences in how we respond to human versus machine opponents.
Published Technology advance paves way to more realistic 3D holograms for virtual reality and more



Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.
Published Origami-inspired robots can sense, analyze and act in challenging environments


A multidisciplinary team has created a new fabrication technique for fully foldable robots that can perform a variety of complex tasks without relying on semiconductors.
Published Robotic hand can identify objects with just one grasp


Newly created soft-rigid robotic fingers incorporate powerful sensors along their entire length, enabling them to produce a robotic hand that could accurately identify objects after only one grasp.
Published English language pushes everyone -- even AI chatbots -- to improve by adding



A linguistic bias in the English language that leads us to 'improve' things by adding to them, rather than taking away, is so common that it is even ingrained in AI chatbots, a new study reveals.
Published Yak milk consumption among Mongol Empire elites


For the first time, researchers have pinpointed a date when elite Mongol Empire people were drinking yak milk, according to a new study.
Published Researchers use 21st century methods to record 2,000 years of ancient graffiti in Egypt


Researchers are learning more about ancient graffiti -- and their intriguing comparisons to modern graffiti -- as they produce a state-of-the-art 3D recording of the Temple of Isis in Philae, Egypt.
Published Can AI predict how you'll vote in the next election?


Artificial intelligence technologies like ChatGPT are seemingly doing everything these days: writing code, composing music, and even creating images so realistic you'll think they were taken by professional photographers. Add thinking and responding like a human to the conga line of capabilities. A recent study proves that artificial intelligence can respond to complex survey questions just like a real human.
Published Ancient DNA reveals Asian ancestry introduced to East Africa in early modern times


The largest-yet analysis of ancient DNA in Africa, which includes the first ancient DNA recovered from members of the medieval Swahili civilization, has now broken the stalemate about the extent to which people from outside Africa contributed to Swahili culture and ancestry.
Published New chip design to provide greatest precision in memory to date


Everyone is talking about the newest AI and the power of neural networks, forgetting that software is limited by the hardware on which it runs. But it is hardware become 'the bottleneck.' New collaborators might change that. They believe that they have developed a new type of chip with the best memory of any chip thus far for edge AI (AI in portable devices). To put it in context, right now, ChatGPT is running on a cloud. The new innovation, followed by some further development, could put the power of a mini version of ChatGPT in everyone's personal device. It could make such high-powered tech more affordable and accessible for all sorts of applications.
Published Ancient giant amphibians swam like crocodiles 250 million years ago


Ancient 2m-long amphibians swam like crocodiles long before true crocodiles existed, according to a new study.
