Published Breathe! The shape-shifting ball that supports mental health
(via sciencedaily.com) A soft ball designed to support mental health by 'personifying' breath has been invented by a computer science student.
Published The scent of the afterlife unbottled in new study of ancient Egyptian mummification balms
(via sciencedaily.com) Original source A team of researchers has recreated one of the scents used in the mummification of an important Egyptian woman more than 3500 years ago.
Published Tiny, shape-shifting robot can squish itself into tight spaces
(via sciencedaily.com) Imagine a robot that can wedge itself through the cracks in rubble to search for survivors trapped in the wreckage of a collapsed building. Engineers are working toward to that goal with CLARI, short for Compliant Legged Articulated Robotic Insect.
Published Paving the way for advanced quantum sensors
(via sciencedaily.com) Quantum physics has allowed for the creation of sensors far surpassing the precision of classical devices. Now, several new studies show that the precision of these quantum sensors can be significantly improved using entanglement produced by finite-range interactions. Researchers were able to demonstrate this enhancement using entangled ion-chains with up to 51 particles.
Published Three-eyed distant relative of insects and crustaceans reveals amazing detail of early animal evolution
(via sciencedaily.com) Original source Scientists use cutting edge scanning technology to reconstruct 'fossil monster' that lived half a billion years ago. The creature's soft anatomy was well-preserved, allowing it to be imaged almost completely: It fills a gap in our understanding of the evolution of arthropods such as insects and crustaceans.
Published AI helps robots manipulate objects with their whole bodies
(via sciencedaily.com) A new AI technique enables a robot to develop complex plans for manipulating an object using its entire hand, not just fingertips. This model can generate effective plans in about a minute using a standard laptop.
Published Scientists invent micrometers-thin battery charged by saline solution that could power smart contact lenses
(via sciencedaily.com) Scientists have developed a flexible battery as thin as a human cornea, which stores electricity when it is immersed in saline solution, and which could one day power smart contact lenses.
Published New dual-arm robot achieves bimanual tasks by learning from simulation
(via sciencedaily.com) An innovative bimanual robot displays tactile sensitivity close to human-level dexterity using AI to inform its actions.
Published Do measurements produce the reality they show us?
(via sciencedaily.com) The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.
Published Newly discovered 'primitive cousins of T rex' shed light on the end of the age of dinosaurs in Africa
(via sciencedaily.com) Original source Researchers have discovered the fossils of two new abelisaurs in Morocco, showing the diversity of dinosaurs in this region at the end of the Cretaceous period.
Published How artificial intelligence gave a paralyzed woman her voice back
(via sciencedaily.com) Researchers have developed a brain-computer interface (BCI) that has enabled a woman with severe paralysis from a brainstem stroke to speak through a digital avatar.
Published Researchers extract ancient DNA from a 2,900-year-old clay brick, revealing a time capsule of plant life
(via sciencedaily.com) Original source For the first time, a group of researchers have successfully extracted ancient DNA from a 2,900-year-old clay brick. The analysis provides a fascinating insight into the diversity of plant species cultivated at that time and place, and could open the way to similar studies on clay material from other sites and time periods.
Published Did sabertooth tigers purr or roar?
(via sciencedaily.com) Original source When a sabertooth tiger called out, what noise did it make -- a mighty roar or a throaty purr? A new study examined the data behind the arguments for each vocalization and found that the answer was more nuanced than they thought -- and that it could depend on the shape of a few small bones.
Published Iceman Ötzi: Dark skin, bald head, Anatolian ancestry
(via sciencedaily.com) Original source A research team has used advanced sequencing technology to analyze Ötzi's genome to obtain a more accurate picture of the Iceman's appearance and genetic origins.
Published 'Resurrecting' the legendary figure behind Count Dracula
(via sciencedaily.com) Original source Vlad III, known as Vlad the Impaler, was a 15th century prince and military leader who was so terrifying, he's thought to have inspired the creation of the literary vampire, Count Dracula. Now, a scientific examination of his letters is giving new insights into his health. Researchers say the results suggest that Vlad probably had skin and respiratory conditions and could have even cried literal tears of blood.
Published Fossil feces infested with parasites from over 200 million years ago
(via sciencedaily.com) Original source Fossilized feces preserve evidence of ancient parasites that infected an aquatic predator over 200 million years ago, according to a new study.
Published Drops of seawater contain traces of an ancient world
(via sciencedaily.com) Original source New research links chemical changes in seawater to volcanic activity and changes.
Published The 'unknome': A database of human genes we know almost nothing about
(via sciencedaily.com) Original source Researchers hope that a new, publicly available database they have created will shrink, not grow, over time. That's because it is a compendium of the thousands of understudied proteins encoded by genes in the human genome, whose existence is known but whose functions are mostly not.
Published Quantum material exhibits 'non-local' behavior that mimics brain function
(via sciencedaily.com) New research shows that electrical stimuli passed between neighboring electrodes can also affect non-neighboring electrodes. Known as non-locality, this discovery is a crucial milestone toward creating brain-like computers with minimal energy requirements.
Published Whale-like filter-feeding discovered in prehistoric marine reptile
(via sciencedaily.com) Original source A remarkable new fossil from China reveals for the first time that a group of reptiles were already using whale-like filter feeding 250 million years ago.
