With the arrival of the Metaverse era, there has been an increase in expectations that virtual reality (VR) and augmented reality (AR) technologies will improve everyday convenience and industry productivity performance. A joint research team has introduced core technology for smart contact lenses to implement AR-based navigation through 3D printing. According to the research team, [..]

Researchers have combined 3D flash and beam-scanning laser light sources to create a 3D, nonmechanical system. According to the researchers, the system can measure the distance of poorly reflective objects in the field of view (FOV) and automatically track their motion — a capability not found in conventional lidar that will allow autonomous vehicles to [..]

Most mainstream commercial solutions for 3D display are based on binocular vision principles to achieve more realistic visual experiences. However, unlike when viewing real 3D objects, the viewer’s depth of visual focus remains constant while wearing the device to obtain 3D information. This vergence accommodation conflict predisposes the viewer to visual fatigue and vertigo, limiting [..]

The C-reactive protein (CRP) is an acute-phase protein that plays a role in inflammation. Furthermore, CRP is a biomarker used in blood analyzer diagnostics to predict the risk of cardiovascular disease (CVD) and monitor bacterial and viral infections. Venipuncture is still required to measure plasma CRP and must be performed by trained phlebotomists. As a [..]

Patients with bone fractures and defects face serious health risks. Synthetic scaffolds have been actively investigated for clinical therapeutics to promote critical-sized bone regeneration, and electrical stimulations are recognized as an effective auxiliary to facilitate the process. Researchers created a three-dimensional (3D) biomimetic scaffold with thin-film silicon (Si) microstructures. This Si-based hybrid scaffold provides a [..]

Researchers have made a significant breakthrough in thermal radiation by discovering a new method for producing spinning thermal radiation in a controlled and efficient manner using artificially structured surfaces known as metasurfaces. Thermal radiation, caused by random fluctuations in materials, has traditionally been regarded as an incoherent signal. The emitted heat from most conventional thermal [..]

Researchers created a tunable laser based on liquid droplets that can be inkjet-printed and have a color that changes depending on the shape, potentially leading to cheaper and more flexible optical communication devices. They demonstrated a straightforward method for creating ionic liquid microdroplets that function as flexible, long-lasting, and pneumatically tunable lasers. Unlike existing “droplet [..]

Many life-saving drugs interact directly with DNA to treat diseases like cancer, but scientists have struggled to understand how and why they work – until now. In a paper, researchers described a new DNA sequencing method to detect where and how small molecule drugs interact with the targeted genome. Understanding how drugs work in the [..]

Scientists have determined the mechanism and functional form for the yield of neutrons from a laser-driven source and used it to carry out a neutron resonance analysis much faster than conventional methods. This work may help bring non-invasive testing to more applications in manufacturing and medicine. While most microscopes use photons or electrons to study [..]

According to new research, PET/MRI achieves comparable or superior results to PET/CT for detecting pulmonary malignancies. Based on those findings, experts involved in the study believe that MRI could play a growing role in lung cancer staging and restaging. Although previous research has yielded somewhat contradictory results on the efficacy of the modality for detecting [..]

Researchers struggle to detect cognition accurately. Functional magnetic resonance imaging (MRI) is currently used to measure brain activity.
