Published Long-distance quantum teleportation enabled by multiplexed quantum memories
(via sciencedaily.com)
Original source 
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 Fossils reveal the long-term relationship between feathered dinosaurs and feather-feeding beetles
(via sciencedaily.com)
Original source 
New fossils in amber have revealed that beetles fed on the feathers of dinosaurs about 105 million years ago, showing a symbiotic relationship of one-sided or mutual benefit.
Published Team designs four-legged robotic system that can walk a balance beam
(via sciencedaily.com)
Original source 
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 New details of Tully monster revealed
(via sciencedaily.com)
Original source 
For more than half a century, the Tully monster (Tullimonstrum gregarium), an enigmatic animal that lived about 300 million years ago, has confounded paleontologists, with its strange anatomy making it difficult to classify. Recently, a group of researchers proposed a hypothesis that Tullimonstrum was a vertebrate similar to cyclostomes (jawless fish like lamprey and hagfish). If it was, then the Tully monster would potentially fill a gap in the evolutionary history of early vertebrates. Studies so far have both supported and rejected this hypothesis. Now, using 3D imaging technology, a team in Japan believes it has found the answer after uncovering detailed characteristics of the Tully monster which strongly suggest that it was not a vertebrate. However, its exact classification and what type of invertebrate it was is still to be decided.
Published Processing data at the speed of light
(via sciencedaily.com)
Original source 
Scientists have developed an extremely small and fast nano-excitonic transistor.
Published It's all in the wrist: Energy-efficient robot hand learns how not to drop the ball
(via sciencedaily.com)
Original source 
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 Table tennis brain teaser: Playing against robots makes our brains work harder
(via sciencedaily.com)
Original source 
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
(via sciencedaily.com)
Original source 
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 How were amino acids, one of the key building blocks of life, formed before the origin of life on Earth?
(via sciencedaily.com)
Original source 
The amino acid abundances of two Ryugu particles were measured and compared with their rocky components. The results demonstrate the important role that water plays in the formation of amino acids on the giant precursors of asteroids like Ryugu. Our solar system formed from a molecular cloud, which was composed of gas and dust that was emitted into the interstellar medium (ISM), a vast space between stars. On collapse of the molecular cloud, the early sun was formed, with a large disk of gas and dust orbiting it. The dusty material collided to produce rocky material that would eventually grow in size to give large bodies called planetesimals.
Published One of Swedish warship Vasa's crew was a woman
(via sciencedaily.com) 
When the human remains found on board the Swedish warship Vasa (1628) were investigated, it was determined that the skeleton designated G was a man. New research now shows that the skeleton is actually from a woman. About thirty people died when Vasa sank on its maiden voyage in Stockholm, 1628. We cannot know who most of them were, only one person is named in the written sources. When the ship was raised in 1961 it was the scene of a comprehensive archaeological excavation, in which numerous human bones were found on board and examined.
Published Origami-inspired robots can sense, analyze and act in challenging environments
(via sciencedaily.com) 
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
(via sciencedaily.com) 
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
(via sciencedaily.com)
Original source 
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
(via sciencedaily.com) 
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
(via sciencedaily.com) 
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 Predatory dinosaurs such as T. rex sported lizard-like lips
(via sciencedaily.com) 
A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths.
Published Can AI predict how you'll vote in the next election?
(via sciencedaily.com) 
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 New chip design to provide greatest precision in memory to date
(via sciencedaily.com) 
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
(via sciencedaily.com) 
Ancient 2m-long amphibians swam like crocodiles long before true crocodiles existed, according to a new study.
Published First silicon integrated ECRAM for a practical AI accelerator
(via sciencedaily.com) 
The transformative changes brought by deep learning and artificial intelligence are accompanied by immense costs. For example, OpenAI's ChatGPT algorithm costs at least $100,000 every day to operate. This could be reduced with accelerators, or computer hardware designed to efficiently perform the specific operations of deep learning. However, such a device is only viable if it can be integrated with mainstream silicon-based computing hardware on the material level.
