There is a great need to generate various types of cells for use in new therapies to replace tissues that are lost due to disease or injuries, or for studies outside the human body to improve our understanding of how organs and tissues function in health and disease. Many of these efforts start with human induced pluripotent stem cells (iPSCs) that, in theory, have the capacity … [Read more...] about A computational guide to lead cells down desired differentiation paths

Computer engineers at the world's largest companies and universities are using machines to scan through tomes of written material. The goal? Teach these machines the gift of language. Do that, some even claim, and computers will be able to mimic the human brain. But this impressive compute capability comes with real costs, including perpetuating racism and causing significant … [Read more...] about Large computer language models carry environmental, social risks

In the field of robotics, metals offer advantages like strength, durability, and electrical conductivity. But, they are heavy and rigid -- properties that are undesirable in soft and flexible systems for wearable computing and human-machine interfaces. Hydrogels, on the other hand, are lightweight, stretchable, and biocompatible, making them excellent materials for contact … [Read more...] about Unique Ag-hydrogel composite for soft bioelectronics created

One of the most classic algorithmic problems deals with calculating the shortest path between two points. A more complicated variant of the problem is when the route traverses a changing network -- whether this be a road network or the internet. For 40 years, an algorithm has been sought to provide an optimal solution to this problem. Now, computer scientist Christian … [Read more...] about Classic math conundrum solved: Superb algorithm for finding the shortest route

Artificial intelligence is part of our modern life. A crucial question for practical applications is how fast such intelligent machines can learn. An experiment has answered this question, showing that quantum technology enables a speed-up in the learning process. The physicists have achieved this result by using a quantum processor for single photons as a robot. Robots solving … [Read more...] about Robots learn faster with quantum technology

Researchers at UCL have solved a major piece of the puzzle that makes up the ancient Greek astronomical calculator known as the Antikythera Mechanism, a hand-powered mechanical device that was used to predict astronomical events. Known to many as the world's first analogue computer, the Antikythera Mechanism is the most complex piece of engineering to have survived from the … [Read more...] about Experts recreate a mechanical Cosmos for the world’s first computer

Anxiety levels in the United States are rising sharply and have especially intensified in younger populations. According to the Anxiety and Depression Association of America, anxiety disorders affect 31.9 percent of children ages 13 to 18 years old. Because of the COVID-19 pandemic, children and adolescents have experienced unprecedented interruptions to their daily lives and … [Read more...] about A remote, computerized training program eases anxiety in children: Researchers first to explore relationship between anxiety, inhibitory control and EEG measures in preadolescents

A new study led by Head of the Rokers Vision Laboratory and NYUAD Associate Professor of Psychology Bas Rokers explored why the severity of motion sickness varies from person to person by investigating sources of cybersickness during VR use. In the new study, Variations in visual sensitivity predict motion sickness in virtual reality published in the journal Entertainment … [Read more...] about Predicting motion sickness severity from virtual reality

Scientists from the Institute of Industrial Science at The University of Tokyo demonstrated how the adaptive immune system uses a method similar to reinforcement learning to control the immune reaction to repeat infections. This work may lead to significant improvements in vaccine development and interventions to boost the immune system. In the human body, the adaptive immune … [Read more...] about Learning to help the adaptive immune system

Researchers have struck quantum gold -- and created a new word -- by enlisting machine learning to efficiently navigate a 20-dimensional quantum treasure map. Physicist Dr Markus Rambach from the ARC Centre of Excellence for Engineered Quantum Systems (EQUS) at The University of Queensland said the team was able to find unknown quantum states more quickly and accurately, using … [Read more...] about Finding quvigints in a quantum treasure map
