Integrated into a high-resolution wireless biosensing device, the antennas could enable researchers to decode complex electrical signals generated by cells.

Monitoring electrical signals in biological systems allows scientists to study how cells communicate, providing valuable insights that can improve the diagnosis and treatment of conditions such as arrhythmia and Alzheimer’s disease.

But devices that record electrical signals in cell cultures and other liquid environments often use wires to connect each electrode on the device to its respective amplifier. Because only so many wires can be connected to the device, this restricts the number of recording sites, limiting the information that can be collected from cells.

A groundbreaking study has revealed a new regime of cooperative radiative phenomena, addressing a 70-year-old puzzle in quantum optics.

By using arrays of synthetic atoms and ultracold matter waves, they uncovered previously unseen collective spontaneous emission effects. These findings not only advance our understanding of fundamental quantum behaviors but also hold promise for practical applications, such as enhancing long-distance quantum networks and improving technologies in quantum science.

Researchers are developing a groundbreaking, non-medication approach to combat insomnia, particularly in military personnel.

By using a novel brain stimulation technique that targets specific brain networks, the team led by William “Scott” Killgore aims to significantly enhance sleep quality and readiness in service members. Their promising initial results have led to a larger study to further validate and refine this technology.

OpenAI CEO Sam Altman said the first artificial intelligence agents might enter the workforce this year as his company inches closer to developing humanlike artificial general intelligence (AGI).

“We believe that, in 2025, we may see the first AI agents ‘join the workforce’ and materially change the output of companies,” said Altman in a blog post titled “Reflections” on Jan. 6.

AI agents or agentic AI refers to artificial intelligence systems that exhibit autonomous decision-making and goal-directed behavior. They can autonomously understand complex goals, make decisions, take actions with minimal human intervention and execute multi-step reasoning processes.

A study led by researchers from the Indiana University School of Medicine, Washington University in St. Louis, and other institutions has identified neuroanatomical differences in children associated with early substance use initiation.

Early-age substance use is strongly associated with a heightened risk for substance use disorders (SUDs) and other adverse outcomes later in life. Neuroanatomical changes in brain structure have been linked to substance use, especially in youth when the brain is undergoing substantial development.

But are the changes seen in substance user brains primarily a result of the substance use itself, or is it an inherent predisposition in some individuals with certain neuroanatomical variations?

Shooting a laser pulse at a porous silver target generates more intense x rays than previous targets, which will help studies of matter in extreme conditions.

Physicists rely on intense bursts of high-energy x rays to observe the progress of fusion experiments and to probe the dynamics of matter under conditions of extreme temperature and pressure. Current techniques for generating such bursts involve firing a laser pulse at a material target but typically turn only a small fraction of the laser energy into usable x rays, thereby limiting the burst energy and intensity. Now researchers have demonstrated a doubling of the efficiency by using a target made of a low-density metallic foam [1]. They expect that the new targets will lead to much brighter x-ray bursts capable of illuminating extreme physical processes under conditions that were previously inaccessible to x-ray observations.

When a powerful laser pulse strikes a foil of material such as silver, the laser strips away the electrons, leaving exposed the highly charged nuclei. Surrounding electrons then fall back into the lowest energy levels, creating high-energy x rays. However, most of the laser energy can be lost in the process, and the overall efficiency is very sensitive to the nature of the material target. Researchers have found, for example, that solid targets generally yield low efficiencies, as x rays emerge from only a small volume near the surface, while laser energy is otherwise consumed by stirring up plasma waves in the material. This low efficiency limits the x-ray intensity.

Researchers at Cornell University have created a sustainable method to extract gold from electronic waste and use it as a catalyst to transform CO₂ into valuable organic materials.

This process provides an eco-friendly alternative to traditional extraction methods, utilizes vast amounts of e-waste, and helps mitigate CO₂ emissions, showcasing a promising avenue for environmental conservation and resource recovery.

Scientists to examine if humans’ and dogs’ brains synchronise when they interact in a way similar to parents and babies.

Not a dramatic increase, but a good one.

Loyal, a US biotech startup, has been conducting research and development on LOY-002, a potential drug for extending the lifespan of dogs.
