Published Old-growth trees more drought tolerant than younger ones, providing a buffer against climate change



A new analysis of more than 20,000 trees on five continents shows that old-growth trees are more drought tolerant than younger trees in the forest canopy and may be better able to withstand future climate extremes. The findings highlight the importance of preserving the world's remaining old-growth forests, which are biodiversity strongholds that store vast amounts of planet-warming carbon, according to forest ecologists.
Published Crowding makes time seem to pass more slowly


Testing time perception in an unusually lifelike setting -- a virtual reality ride on a New York City subway train -- an interdisciplinary research team found that crowding makes time seem to pass more slowly.
Published Mammoth problem with extinction timeline



Paleontologists say environmental DNA is not always helpful in identifying when animals like mammoths went extinct because genetic material found in sediment could have come from animals that died thousands of years earlier.
Published 1930s Dust Bowl led to extreme heat around Northern Hemisphere


The 1930s Dust Bowl affected heat extremes across much of North America and as far away as Europe and East Asia, according to new research. The study found that the extreme heating of the Great Plains triggered motions of air around the Northern Hemisphere in ways that suppressed cloud formation in some regions and contributed to record heat thousands of miles away.
Published Interdisciplinary environmental history: How narratives of the past can meet the challenges of the anthropocene


A new article discusses vital methodological issues for humanities-based historical inquiry and argues that the challenges of the Anthropocene demand interdisciplinary research informed by a variety of historical narratives.
Published What ancient underwater food webs can tell us about the future of climate change


Have humans wreaked too much havoc on marine life to halt damage? A new analysis challenges the idea that ocean ecosystems have barely changed over millions of years, pointing scientists down a new path on conservation efforts and policy.
Published The evolution of Asia's mammals was dictated by ancient climate change and rising mountains


A new study compiles data on more than 3,000 species to show how climate and geologic changes across Asia over the last 66 million years have shaped the evolution of the continent's mammals.
Published Math approach may make drug discovery more effective, efficient


Researchers have devised a computer-based platform for drug discovery that could make the process more effective, more efficient and less costly.
Published A navigation system with 10 centimeter accuracy


Researchers have developed an alternative positioning system that is more robust and accurate than GPS, especially in urban settings. The working prototype that demonstrated this new mobile network infrastructure achieved an accuracy of 10 centimeter. This new technology is important for the implementation of a range of location-based applications, including automated vehicles, quantum communication and next-generation mobile communication systems.
Published All solid-state LiDAR sensor that sees 360°


A research team develops a fixed LiDAR sensor that can recognize all directions simultaneously.
Published Virtual reality experiences to aid substance use disorder recovery


Researchers are combining psychological principles with innovative virtual reality technology to create a new immersive therapy for people with substance use disorders.
Published Smelling in VR environment possible with new gaming technology


An odor machine, so-called olfactometer, makes it possible to smell in VR environments. First up is a 'wine tasting game' where the user smells wine in a virtual wine cellar and gets points if the guess on aromas in each wine is correct. The new technology can be printed on 3D printers.
Published Video games offer the potential of 'experiential medicine'


After a decade of work, scientists have developed a suite of video game interventions that improve key aspects of cognition in aging adults.
Published An AI message decoder based on bacterial growth patterns


Depending on the initial conditions used, such as nutrient levels and space constraints, bacteria tend to grow in specific ways. Researchers have created a new type of encryption scheme based on how a virtual bacterial colony grows with specific initial conditions.
Published Can eyes on self-driving cars reduce accidents?


Robotic eyes on autonomous vehicles could improve pedestrian safety, according to a new study. Participants played out scenarios in virtual reality (VR) and had to decide whether to cross a road in front of a moving vehicle or not. When that vehicle was fitted with robotic eyes, which either looked at the pedestrian (registering their presence) or away (not registering them), the participants were able to make safer or more efficient choices.
Published New method for comparing neural networks exposes how artificial intelligence works


A team has developed a novel approach for comparing neural networks that looks within the 'black box' of artificial intelligence to help researchers understand neural network behavior. Neural networks recognize patterns in datasets; they are used everywhere in society, in applications such as virtual assistants, facial recognition systems and self-driving cars.
Published Optical rule was made to be broken


Engineers find a way to identify nanophotonic materials with the potential to improve screens for virtual reality and 3D displays along with optical technologies in general.
Published City digital twins help train deep learning models to separate building facades


To automatically generate data for training deep convolutional neural network models to segment building facades, researchers used a three-dimensional model and game engine to generate digital city twin synthetic training data. They found that a model trained on these data mixed with some real data was competitive with a model trained on real data alone, revealing the potential of digital twin data to improve accuracy and replace costly manually annotated real data.
Published New chip-based beam steering device lays groundwork for smaller, cheaper lidar


Researchers have developed a new chip-based beam steering technology that provides a promising route to small, cost-effective and high-performance lidar systems. Lidar, which uses laser pulses to acquire 3D information about a scene or object, is used in a wide range of applications such as autonomous driving, free-space optical communications, 3D holography, biomedical sensing and virtual reality. Researchers describe their new chip-based optical phased array (OPA) that solves many of the problems that have plagued previous OPA designs.
Published Augmented reality could be the future of paper books, according to new research


Augmented reality might allow printed books to make a comeback against the e-book trend, according to researchers.
