Published New superconducting diode could improve performance of quantum computers and artificial intelligence
(via sciencedaily.com) Original source A team has developed a more energy-efficient, tunable superconducting diode -- a promising component for future electronic devices -- that could help scale up quantum computers for industry and improve artificial intelligence systems.
Published Robot 'chef' learns to recreate recipes from watching food videos
(via sciencedaily.com) Original source Researchers have trained a robotic 'chef' to watch and learn from cooking videos, and recreate the dish itself.
Published Shining a light on neuromorphic computing
(via sciencedaily.com) Original source AI, machine learning, and ChatGPT may be relatively new buzzwords in the public domain, but developing a computer that functions like the human brain and nervous system -- both hardware and software combined -- has been a decades-long challenge. Engineers are exploring how optical "memristors" may be a key to developing neuromorphic computing.
Published Quantum computers are better at guessing, new study demonstrates
(via sciencedaily.com) Original source Researchers have demonstrated a quantum speedup over the most efficient classical computer algorithm possible for what is believed to be the first time. The accomplishment was performed on an IBM Montreal Quantum Falcon r4 27-qubit device.
Published New method improves efficiency of 'vision transformer' AI systems
(via sciencedaily.com) Original source Vision transformers (ViTs) are powerful artificial intelligence (AI) technologies that can identify or categorize objects in images -- however, there are significant challenges related to both computing power requirements and decision-making transparency. Researchers have now developed a new methodology that addresses both challenges, while also improving the ViT's ability to identify, classify and segment objects in images.
Published Geneticists discover hidden 'whole genome duplication' that may explain why some species survived mass extinctions
(via sciencedaily.com) Original source Geneticists have unearthed a major event in the ancient history of sturgeons and paddlefish that has significant implications for the way we understand evolution. They have pinpointed a previously hidden 'whole genome duplication' (WGD) in the common ancestor of these species, which seemingly opened the door to genetic variations that may have conferred an advantage around the time of a major mass extinction some 200 million years ago.
Published 4,000-year-old plague DNA found -- the oldest cases to date in Britain
(via sciencedaily.com) Original source Researchers have identified three 4,000-year-old British cases of Yersinia pestis, the bacteria causing the plague -- the oldest evidence of the plague in Britain to date.
Published Robot centipedes go for a walk
(via sciencedaily.com) Original source Researchers show how their multilegged walking robot can be steered by inducing a dynamic instability. By making the couplings between segments more flexible, the robot changes from walking straight to moving in a curved path. This work can lead to more energy-efficient and reliable robotic navigation of terrain.
Published Effective as a collective: Researchers investigate the swarming behavior of microrobots
(via sciencedaily.com) Original source Miniaturization is progressing rapidly in just any field and the trend towards the creation of ever smaller units is also prevalent in the world of robot technology. In the future, minuscule robots used in medical and pharmaceutical applications might be able to transport medication to targeted sites in the body. Statistical physics can contribute to the foundations for the development of such technologies.
Published Early toilets reveal dysentery in Old Testament Jerusalem
(via sciencedaily.com) Original source Study of 2,500-year-old latrines from the biblical Kingdom of Judah shows the ancient faeces within contain Giardia -- a parasite that can cause dysentery.
Published Robots and Rights: Confucianism Offers Alternative
(via sciencedaily.com) Original source As robots assume more roles in the world, a new analysis reviewed research on robot rights, concluding that granting rights to robots is a bad idea. Instead, the article looks to Confucianism to offer an alternative.
Published Researchers build bee robot that can twist
(via sciencedaily.com) Original source A robotic bee that can fly fully in all directions has been developed. With four wings made out of carbon fiber and mylar as well as four light-weight actuators to control each wing, the Bee++ prototype is the first to fly stably in all directions. That includes the tricky twisting motion known as yaw, with the Bee++ fully achieving the six degrees of free movement that a typical flying insect displays.
Published Dinosaurs were the first to take the perspectives of others
(via sciencedaily.com) Original source Understanding that others hold different viewpoints from your own is essential for human sociality. Adopting another person's visual perspective is a complex skill that emerges around the age of two. A new study suggests that this ability first arose in dinosaurs, at least 60 million years before it appeared in mammals. These findings challenge the idea that mammals were the originators of novel and superior forms of intelligence in the wake of the dinosaur extinction.
Published Earliest evidence of wine consumption in the Americas found in Caribbean
(via sciencedaily.com) Original source Scientists have found what they believe to be the earliest known evidence of wine drinking in the Americas, inside ceramic artefacts recovered from a small Caribbean island.
Published Humanity's earliest recorded kiss occurred in Mesopotamia 4,500 years ago
(via sciencedaily.com) Original source Written sources from Mesopotamia suggest that kissing in relation to sex was practiced by the peoples of the ancient Middle East 4,500 years ago.
Published Homo sapiens likely arose from multiple closely related populations
(via sciencedaily.com) Original source In testing the genetic material of current populations in Africa and comparing against existing fossil evidence of early Homo sapiens populations there, researchers have uncovered a new model of human evolution -- overturning previous beliefs that a single African population gave rise to all humans.
Published Can't find your phone? There's a robot for that
(via sciencedaily.com) Original source Engineers have discovered a new way to program robots to help people with dementia locate medicine, glasses, phones and other objects they need but have lost.
Published New study illustrates unique genetic landscape in Newfoundland and Labrador with links to Ireland and England
(via sciencedaily.com) Original source A new study has produced the most detailed genetic analysis of people living in the Canadian province of Newfoundland to date, demonstrating a unique founder population structure that could be used for the identification and study of health-related genetic variants.
Published Researcher uses mammal DNA to zoom into the human genome with unprecedented resolution
(via sciencedaily.com) Original source Scientists have precisely identified base pairs of the human genome that remained consistent over millions of years of mammalian evolution, and which play a crucial role in human disease. The team analyzed the genomes of 240 mammals, including humans and identified base pairs that were 'constrained' -- meaning they remained generally consistent -- across mammal species over the course of evolution. The most constrained base pairs in mammals were over seven times more likely to be causal for human disease and complex trait, and over 11 times more likely when researchers looked at the most constrained base pairs in primates alone.
Published Better than humans: Artificial intelligence in intensive care units
(via sciencedaily.com) Original source With the help of extensive data from intensive care units of various hospitals, an artificial intelligence was developed that provides suggestions for the treatment of people who require intensive care due to sepsis. Analyses show that artificial intelligence already surpasses the quality of human decisions. However, it is now important to also discuss the legal aspects of such methods.
