Researchers have used a series of artificial stream channels to mimic the behavior of headwater creeks under future climate change scenarios. They found that drier conditions shifted the life cycles of the algae and insects that form the base of the alpine food web. However, because species adjusted to the shifts in a variety of ways, the stream ecosystems were generally resilient to the changing conditions.

The traveling salesman problem is considered a prime example of a combinatorial optimization problem. Now a team has shown that a certain class of such problems can actually be solved better and much faster with quantum computers than with conventional methods.

A novel mixed light field technique that utilizes a mix of ray-controlled ambient lighting with projection mapping (PM) to obtain PM in bright surroundings has been developed by scientists. This innovative technology utilizes a novel kaleidoscope array to achieve ray-controlled lighting and a binary search algorithm for removing ambient lighting from PM targets. It provides an immersive augmented reality experience with applications in various fields.

A curious aspect of tree frogs is that they often lay their eggs on the ground where the risk of predation by natural enemies is greater than in the trees where they live. A research team suggested that the reason for this behavior is to protect the eggs from low temperatures. Their findings highlight the challenge faced by tree frogs: Should they attempt to maintain an optimal temperature for their eggs or risk predation?

Imagine performing a sweep around an object with your smartphone and getting a realistic, fully editable 3D model that you can view from any angle -- this is fast becoming reality, thanks to advances in AI. Researchers have unveiled new AI technology for doing exactly this. Soon, rather than merely taking 2D photos, everyday consumers will be able to take 3D captures of real-life objects and edit their shapes and appearance as they wish, just as easily as they would with regular 2D photos today.

Neural networks have been powering breakthroughs in artificial intelligence, including the large language models that are now being used in a wide range of applications, from finance, to human resources to healthcare. But these networks remain a black box whose inner workings engineers and scientists struggle to understand. Now, a team has given neural networks the equivalent of an X-ray to uncover how they actually learn.

In the quest to develop quantum computers and networks, there are many components that are fundamentally different than those used today. Like a modern computer, each of these components has different constraints. However, it is currently unclear what materials can be used to construct those components for the transmission and storage of quantum information.
