Researchers developed an automated system to help programmers increase the efficiency of their deep learning algorithms by simultaneously leveraging two types of redundancy in complex data structures: sparsity and symmetry.

Researchers have developed a computer model to help scientists identify tumor-fighting immune cells in patients with lung cancer treated with immune checkpoint inhibitors.

Electrochemical reaction-based stimuli-responsive materials are shaping up the era of innovative display devices. By embedding luminescent europium(III) complexes and color-changing viologen derivatives in a layered clay matrix, the device achieves simultaneous control of light emission and color at low voltage. The use of clay-based materials also highlights an eco-friendly approach to enhancing electronic device performance. This innovation could revolutionize display technology and the development of sensors, adaptable to changing light conditions.

Engineers developed a training method for multiagent systems, such as large numbers of drones, that can guarantee their safe operation in crowded environments.

With the growing popularity of telehealth comes new issues with billing.

The development of vehicle components is a lengthy and therefore very costly process. Researchers have developed a method that can shorten the development phase of the powertrain of battery electric vehicles by several months. A team is combining simulation models of components with evolutionary optimization algorithms. This AI system automatically optimizes the entire powertrain -- from the power electronics to the electric machine through to the transmission -- in line with the manufacturer's technical requirements, taking into account targets such as production costs, efficiency and package space requirements in the vehicle.

Skyrmions are nanometer- to micrometer-sized magnetic whirls that exhibit particle-like properties and can be moved efficiently by electrical currents. These properties make skyrmions an excellent system for new types of data storage or computers. However, for the optimization of such devices, it is usually too computationally expensive to simulate the complicated internal structure of the skyrmions. One possible approach is the efficient simulation of these magnetic spin structures as particles, similar to the simulation of molecules in biophysics. Until now, however, there has been no conversion between simulation time and experimental real time.

By analyzing almost 10,000 pregnancies, researchers discovered previously unidentified combinations of risk factors linked to serious negative pregnancy outcomes, finding that there may be up to a tenfold difference in risk for infants who are currently treated identically under clinical guidelines.

Researchers have developed a new material that harnesses the power of enzymes more effectively. These materials have improved the reaction efficiency and long-term stability of enzymes in electrochemical biosensors used in health care and other applications. Furthermore, the researchers significantly enhanced device performance.

The electronics of the future can be made even smaller and more efficient by getting more memory cells to fit in less space. One way to achieve this is by adding the noble gas xenon when manufacturing digital memories. This technology enables a more even material coating even in small cavities.

Personalized medicine aims to tailor treatments to individual patients. Until now, this has been done using a small number of parameters to predict the course of a disease. However, these few parameters are often not enough to understand the complexity of diseases such as cancer. A team of researchers has developed a new approach to this problem using artificial intelligence (AI).

A new study shows that artificial intelligence (AI) can help doctors make better decisions when treating cancer. However, it also highlights challenges in how doctors and AI work together. The study focused on AI-assisted radiotherapy for non-small cell lung cancer and hepatocellular carcinoma (liver cancer).

A study suggests that a computer-generated breathing coach could be as effective as sessions with a human trainer.

Researchers developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate.

AI agents trained in simulations that differ from the environments where they are deployed sometimes perform better than agents trained and deployed in the same environment, research shows.

Many materials store information about what has happened to them in a sort of material memory, like wrinkles on a once crumpled piece of paper. Now, a team of physicists has uncovered how, under specific conditions, some materials seemingly violate underlying mathematics to store memories about the sequence of previous deformations.

This novel finding regarding the nonreciprocal diffraction of acoustic waves could open doors for next-generation communication devices.

The universe is getting more disordered, entropy is growing -- this is the second law of thermodynamics. But according to quantum theory, entropy should actually stay the same. Scientists took a closer look and resolved this apparent contradiction.

The narrow, deep holes required for one type of flash memory are made twice as fast with the right recipe, which includes a plasma made from hydrogen fluoride.

In a groundbreaking achievement for quantum technologies, researchers have created a functional quantum register using the atoms inside a semiconductor quantum dot.
