Simulating Evolution to Understand a Hidden Genetic Switch

Computer simulations of cells evolving over tens of thousands of generations reveal why some organisms retain a disused switch mechanism that turns on under severe stress, changing some of their characteristics. Maintaining this “hidden” switch is one means for organisms to maintain a high degree of gene expression stability under normal conditions. Tomato hornworm larvae […]

Important Milestone in the Creation of a Quantum Computer That Uses Transistors As Qubits

One of the obstacles for progress in the quest for a working quantum computer has been that the working devices that go into a quantum computer and perform the actual calculations, the qubits, have hitherto been made by universities and in small numbers. But in recent years, a pan-European collaboration, in partnership with French microelectronics […]

Giving Computers a Keen Sense of Smell – Researchers Create a Biohybrid Olfactory Sensor

A keen sense of smell is a powerful ability shared by many organisms. However, it has proven difficult to replicate by artificial means. Researchers combined biological and engineered elements to create what is known as a biohybrid component. Their volatile organic compound sensor can effectively detect odors in gaseous form. They hope to refine the […]

Error Protected Quantum Bits Entangled: A Milestone in the Development of Fault-Tolerant Quantum Computers

Even computers can miscalculate. Already small disturbances change stored information and corrupt results. That is why computers use methods to continuously correct such errors. In quantum computers, the vulnerability to errors can be reduced by storing quantum information in more than a single quantum particle. These logical quantum bits are less sensitive to errors. In […]

Lack of Sleep Could Be a Problem for Artificial Intelligence

One of the distinguishing features of machines is that they don’t need to sleep, unlike humans and any other creature with a central nervous system. Someday though, your toaster might need a nap from time to time, as may your car, fridge and anything else that is revolutionized with the advent of practical artificial intelligence […]
