Published Could an electric nudge to the head help your doctor operate a surgical robot?



People who received gentle electric currents on the back of their heads learned to maneuver a robotic surgery tool in virtual reality and then in a real setting much more easily than people who didn't receive those nudges, a new study shows.
Published Cognitive strategies for augmenting the body with a wearable, robotic arm



Scientists show that breathing may be used to control a wearable extra robotic arm in healthy individuals, without hindering control of other parts of the body.
Published Immersive VR goggles for mice unlock new potential for brain science



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.
Published Scientists propose a model to predict personal learning performance for virtual reality-based safety training



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.
Published To help autonomous vehicles make moral decisions, researchers ditch the 'trolley problem'



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.'
Published Immersive engagement in mixed reality can be measured with reaction time



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.
Published Massive 2022 eruption reduced ozone layer levels



The Hunga Tonga-Hunga Ha'apai volcano changed the chemistry and dynamics of the stratosphere in the year following the eruption, leading to unprecedented losses in the ozone layer of up to 7% over large areas of the Southern Hemisphere.
Published When we feel things that are not there



The discovery of the phantom touch illusion provides insights into human perception and opens up new perspectives for interaction with virtual reality technology.
Published Machine learning gives users 'superhuman' ability to open and control tools in virtual reality



Researchers have developed a virtual reality application where a range of 3D modelling tools can be opened and controlled using just the movement of a user's hand.
Published Human emissions increased mercury in the atmosphere sevenfold



Researchers estimated that before humans started pumping mercury into the atmosphere, it contained on average about 580 megagrams of mercury. However, in 2015, independent research that looked at all available atmospheric measurements estimated the atmospheric mercury reservoir was about 4,000 Mg -- nearly 7 times larger than the natural condition estimated in this study.
Published Virtual meetings tire people because we're doing them wrong



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.
Published Robot stand-in mimics movements in VR



Researchers have developed a souped-up telepresence robot that responds automatically and in real-time to a remote user's movements and gestures made in virtual reality.
Published Mystery of volcanic tsunami solved after 373 years



The explosion of the underwater volcano Kolumbo in the Aegean Sea in 1650 triggered a destructive tsunami that was described by historical eye witnesses. A group of researchers has now surveyed Kolumbo's underwater crater with modern imaging technology and reconstructed the historical events. They found that the eyewitness accounts of the natural disaster can only be described by a combination of a landslide followed by an explosive eruption.
Published Simulating cold sensation without actual cooling



The perception of persistent thermal sensations, such as changes in temperature, tends to gradually diminish in intensity as our bodies become accustomed to the temperature. This phenomenon leads to a shift in our perception of temperature when transitioning between different scenes in a virtual environment. Researchers have now developed a technology to generate a virtual cold sensation via a non-contact method without physically altering the skin temperature.
Published California supervolcano is cooling off but may still cause quakes



New high-resolution images of the Long Valley Caldera indicate that the subsurface environment is cooling off, releasing gas and fluids that contribute to seismic activity.
Published Virtual reality helps people with hoarding disorder practice decluttering



A new study lets patients practice letting go of treasured objects in simulations of their own homes.
Published Virtual driving assessment predicts risk of crashing for newly licensed teen drivers



New research found that driving skills measured at the time of licensure on a virtual driving assessment (VDA), which exposes drivers to common serious crash scenarios, helps predict crash risk in newly licensed young drivers. This study brings the research community one step closer to identifying which skill deficits put young new drivers at higher risk for crashes. With this cutting-edge information, more personalized interventions can be developed to improve the driving skills that prevent crashes.
Published Volcanic ash effects on Earth systems



To bridge the knowledge gap between volcanologists and atmospheric scientists working on climate change and observing global systems, researchers have characterized volcanic ash samples from many explosive eruptions of a broad compositional range.
Published New internet addiction spectrum: Where are you on the scale?



Young people (24 years and younger) spend an average of six hours a day online, primarily using their smartphones, according to new research. Older people (those 24 years and older) spend 4.6 hours online.
Published Drug discovery on an unprecedented scale


Boosting virtual screening with machine learning allowed for a 10-fold time reduction in the processing of 1.56 billion drug-like molecules. Researchers teamed up with industry and supercomputers to carry out one of the world's largest virtual drug screens.
