New miniature virtual reality (VR) goggles provide more immersive experiences for mice living in laboratory settings. By more faithfully simulating natural environments, the researchers can more accurately and precisely study the neural circuitry that underlies behavior. Compared to current state-of-the-art systems, which simply surround mice with computer or projection screens, the new goggles provide a leap in advancement.

Chemists have now come up with a way to make molecules known as acenes more stable, allowing them to synthesize acenes of varying lengths. Using their new approach, they were able to build molecules that emit red, orange, yellow, green, or blue light, which could make acenes easier to deploy in a variety of applications.

Amid the rubble of large-sale earthquake, war or other disaster -- and as ageing buildings and infrastructure are replaced -- mountains of concrete are often taken to landfill or pounded into rubble for roads. For a more sustainable approach, experts are developing a 'value add' for old broken concrete to 'upcycling' coarse aggregate to produce a strong, durable and workable concrete using a small amount of a secret ingredient -- graphene.

Graphene, that is extremely thin carbon, is considered a true miracle material. An international research team has now added another facet to its diverse properties with new experiments: Experts fired short terahertz pulses at micrometer-sized discs of graphene, which briefly turned these minuscule objects into surprisingly strong magnets. This discovery may prove useful for developing future magnetic switches and storage devices.

In Korea, workers are being provided with virtual reality (VR)-based safety training content to mitigate the increase in occupational accidents. However, the current training evaluation methods suffer from a lack of immediate feedback from participants for personal learning performance evaluation. To address this, a team of researchers has now developed a new framework that uses real-time biometric data during VR training for improving personalized safety and preventing occupational hazards.

Researchers have developed a new experiment to better understand what people view as moral and immoral decisions related to driving vehicles, with the goal of collecting data to train autonomous vehicles how to make 'good' decisions. The work is designed to capture a more realistic array of moral challenges in traffic than the widely discussed life-and-death scenario inspired by the so-called 'trolley problem.'

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.

Sodium- and potassium-ion batteries are promising next-generation alternatives to the ubiquitous lithium-ion batteries (LIBs). However, their energy density still lags behind that of LIBs. To tackle this issue, researchers explored an innovative strategy to turn hard carbon into an excellent negative electrode material. Using inorganic zinc-based compounds as a template during synthesis, they prepared nanostructured hard carbon, which exhibits excellent performance in both alternative batteries.

Researchers have unveiled a remarkable new material with potential to impact the world of material science: amorphous silicon carbide (a-SiC). Beyond its exceptional strength, this material demonstrates mechanical properties crucial for vibration isolation on a microchip. Amorphous silicon carbide is therefore particularly suitable for making ultra-sensitive microchip sensors.

New research suggests sleepiness during virtual meetings is caused by mental underload and boredom. Earlier studies suggested that fatigue from virtual meetings stems from mental overload, but new research shows that sleepiness during virtual meetings might actually be a result of mental underload and boredom.
