Published Immersive engagement in mixed reality can be measured with reaction time
(via sciencedaily.com) Original source 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 Earliest known European common hippopotamus fossil reveals their Middle Pleistocene dispersal
(via sciencedaily.com) Original source Modern hippos first dispersed in Europe during the Middle Pleistocene, according to a new study.
Published Like the phoenix, Australia's giant birds of prey rise again from limestone caves
(via sciencedaily.com) Original source Australia's only vulture, and a fearsome extinct eagle, are among the earliest recorded birds of prey from the Pleistocene period more than 50,000 years ago -- and now researchers are bringing them to 'life' again. Along with new scientific information, a bold new pictorial reconstruction of a newly named eagle and the only known Australian vulture will be unveiled at the World Heritage-listed Naracoorte Caves in South Australia's Limestone Coast this month.
Published Birds set foot near South Pole in Early Cretaceous, Australian tracks show
(via sciencedaily.com) Original source The discovery of 27 avian footprints on the southern Australia coast -- dating back to the Early Cretaceous when Australia was still connected to Antarctica -- opens another window onto early avian evolution and possible migratory behavior.
Published Plants that survived dinosaur extinction pulled nitrogen from air
(via sciencedaily.com) Original source Ancient cycad lineages that survived the extinction of the dinosaurs may have done so by relying on symbiotic bacteria in their roots to fix atmospheric nitrogen. The finding came from an effort to understand ancient atmospheres, but became an insight into plant evolution instead.
Published When we feel things that are not there
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Virtual meetings tire people because we're doing them wrong
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Simulating cold sensation without actual cooling
(via sciencedaily.com) Original source 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 Holy bat skull! Fossil adds vital piece to bat evolution puzzle
(via sciencedaily.com) Original source Bats may have lived in caves and used soundwaves to navigate much earlier than first thought.
Published Virtual reality helps people with hoarding disorder practice decluttering
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Extraordinary fossil find reveals details about the weight and diet of extinct saber-toothed marsupial
(via sciencedaily.com) Original source A 13-million-year-old saber-toothed marsupial skeleton discovered during paleontological explorations in Colombia is the most complete specimen recovered in the region.
Published Race to find world's oldest mammal fossils led to mud-slinging
(via sciencedaily.com) Original source The hunt for the world’s most ancient mammals descended into academic warfare in the seventies, researchers have discovered.
Published Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought
(via sciencedaily.com) Original source For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.
Published New internet addiction spectrum: Where are you on the scale?
(via sciencedaily.com) Original source 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 Genome study reveals 30 years of Darwin's finch evolution
(via sciencedaily.com) Original source An international team of researchers has released a landmark study on contemporary evolutionary change in natural populations. Their study uses one of the largest genomic datasets ever produced for animals in their natural environment, comprising nearly 4,000 Darwin's finches. The study has revealed the genetic basis of adaptation in this iconic group.
Published New research reveals extreme heat likely to wipe out humans and mammals in the distant future
(via sciencedaily.com) Original source A new study shows unprecedented heat is likely to lead to the next mass extinction, akin to when the dinosaurs died out, eliminating nearly all mammals in some 250 million years time.
Published Drug discovery on an unprecedented scale
(via sciencedaily.com) 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.
