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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
