(via sciencedaily.com) Original source A new kind of 'wire' for moving excitons could help enable a new class of devices, perhaps including room temperature quantum computers.
Published Unlocking the secrets of cells, with AI
(via sciencedaily.com) Original source Researchers have developed a new program that provides a more accurate understanding of the peptide sequences in cells. The researchers use machine learning to help analyze the makeup of unfamiliar cells, which could lead to more personalized medicine in the treatment of cancer and other serious diseases.
Published Defending your voice against deepfakes
(via sciencedaily.com) Original source Computer scientists have developed AntiFake, a tool to protect voice recordings from unauthorized speech synthesis.
Published Scientist discovers potential brain link between stress, emotional eating
(via sciencedaily.com) Original source Scientists describe how they identified a molecule that may trigger over-consumption of comfort foods after a threatening event.
Published Measuring long-term heart stress dynamics with smartwatch data
(via sciencedaily.com) Original source Biomedical engineers have developed a method using data from wearable devices such as smartwatches to digitally mimic an entire week's worth of an individual's heartbeats. The new 'digital twins' computational framework captures personalized arterial forces over 700,000 heartbeats to better predict risks of heart disease and heart attack. The advance is an important step toward evaluating the risks of heart disease or heart attack over months to years.
Published Immersive engagement in mixed reality can be measured with reaction time
(via sciencedaily.com) Original source In the real world/digital world cross-over of mixed reality, a user's immersive engagement with the program is called presence. Now, researchers have identified reaction time as a potential presence measurement tool. Their findings have implications for calibrating mixed reality to the user in real time.
Published How heat can be used in computing
(via sciencedaily.com) Original source Physicists have demonstrated that, combining specific materials, heat in technical devices can be used in computing. Their discovery is based on extensive calculations and simulations. The new approach demonstrates how heat signals can be steered and amplified for use in energy-efficient data processing.
Published New clues into the head-scratching mystery of itch
(via sciencedaily.com) Original source Scientists show for the first time that bacteria can cause itch by activating nerve cells in the skin. The findings can inform new therapies to treat itch that occurs in inflammatory skin conditions like eczema and dermatitis.
Published Hybrid transistors set stage for integration of biology and microelectronics
(via sciencedaily.com) Original source Researchers create transistors combining silicon with biological silk, using common microprocessor manufacturing methods. The silk protein can be easily modified with other chemical and biological molecules to change its properties, leading to circuits that respond to biology and the environment.
Published Nutrient found in beef and dairy improves immune response to cancer
(via sciencedaily.com) Original source Trans-vaccenic acid (TVA), a long-chain fatty acid found in meat and dairy products from grazing animals such as cows and sheep, improves the ability of CD8+ T cells to infiltrate tumors and kill cancer cells, according to a new study.
Published Team discovers rules for breaking into Pseudomonas
(via sciencedaily.com) Original source Researchers report that they have found a way to get antibacterial drugs through the nearly impenetrable outer membrane of Pseudomonas aeruginosa, a bacterium that -- once it infects a person -- is notoriously difficult to treat.
Published Medical AI tool gets human thumbs-up
(via sciencedaily.com) Original source A new artificial intelligence computer program can generate doctors' notes so well that two physicians couldn't tell the difference, according to an early study from both groups.
Published How we play together
(via sciencedaily.com) Original source Psychologists are using EEG to research what games reveal about our ability to cooperate.

(via sciencedaily.com) Original source Researchers have used laser-powered ‘optical tweezers’ to reveal a universal motor mechanism used by viruses for packaging their DNA into infectious particles.
Published Unearthing how a carnivorous fungus traps and digests worms
(via sciencedaily.com) Original source A new analysis sheds light on the molecular processes involved when a carnivorous species of fungus known as Arthrobotrys oligospora senses, traps and consumes a worm.
Published Coffee grounds may hold key to preventing neurodegenerative diseases
(via sciencedaily.com) Original source A team of researchers found that caffeic-acid based Carbon Quantum Dots (CACQDs), which can be derived from spent coffee grounds, have the potential to protect brain cells from the damage caused by several neurodegenerative diseases.
Published New computer code for mechanics of tissues and cells in three dimensions
(via sciencedaily.com) Original source Biological materials are made of individual components, including tiny motors that convert fuel into motion. This creates patterns of movement, and the material shapes itself with coherent flows by constant consumption of energy. Such continuously driven materials are called 'active matter'. The mechanics of cells and tissues can be described by active matter theory, a scientific framework to understand shape, flows, and form of living materials. The active matter theory consists of many challenging mathematical equations. Scientists have now developed an algorithm, implemented in an open-source supercomputer code, that can for the first time solve the equations of active matter theory in realistic scenarios. These solutions bring us a big step closer to solving the century-old riddle of how cells and tissues attain their shape and to designing artificial biological machines.
