To protect corals from summer heatwaves, we should help their microbial symbionts evolve heat tolerance in the lab      (via sciencedaily.com)     Original source 

Most coral reef restoration efforts involve restocking reefs with nursery-grown corals. However, if these corals are of the same stock as their wild counterparts, they will be equally vulnerable to the heat stress that caused the bleaching event in the first place. Researchers discuss the potential of improving corals' chances by inducing the evolution of heat tolerance in their symbionts -- the mutualistic microbes that provide corals with nutrients in exchange for shelter and that are expelled during coral bleaching.

Researchers find genetic stability in a long-term Panamanian hybrid zone of manakin birds      (via sciencedaily.com)     Original source 

We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stable, and studying them can reveal key insights into how species boundaries evolve -- or sometimes blur. Researchers now describe a hybrid zone between two manakin species in Panama that has overall remained relatively stable over the past 30 years.

Mechanical computer relies on kirigami cubes, not electronics      (via sciencedaily.com)     Original source 

Researchers have developed a kirigami-inspired mechanical computer that uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on electronic components. The system also includes a reversible feature that allows users to control when data editing is permitted and when data should be locked in place.

Balancing act: Novel wearable sensors and AI transform balance assessment      (via sciencedaily.com)     Original source 

Traditional methods to assess balance often suffer from subjectivity, aren't comprehensive enough and can't be administered remotely. They also are expensive and require specialized equipment and clinical expertise. Using wearable sensors and advanced machine learning algorithms, researchers offer a practical and cost-effective solution for capturing detailed movement data, essential for balance analysis. This approach is more accessible and can be administered remotely, which could have significant implications for health care, rehabilitation, sports science or other fields where balance assessment is important.

Discovery of vast sex differences in cellular activity has major implications for disease treatment      (via sciencedaily.com)     Original source 

The study reveals vast differences in gene activity within the mitochondria of males compared to females. This is the first study to test effects of all 37 genes in the mitochondrial genome -- genes that copepods and humans share. The study found that males demonstrate more activity across all protein-coding mitochondrial genes than females. Although the study looks at tiny marine organisms called copepods, the findings have weighty implications for human medicine.

Next platform for brain-inspired computing      (via sciencedaily.com)     Original source 

Computers have come so far in terms of their power and potential, rivaling and even eclipsing human brains in their ability to store and crunch data, make predictions and communicate. But there is one domain where human brains continue to dominate: energy efficiency.

Researchers engineer AI path to prevent power outages      (via sciencedaily.com)     Original source 

Researchers developed an artificial intelligence (AI) model that could help electrical grids prevent power outages by automatically rerouting electricity in milliseconds. The approach is an early example of 'self-healing grid' technology, which uses AI to detect and repair problems such as outages autonomously and without human intervention when issues occur, such as storm-damaged power lines.

Breakthrough may clear major hurdle for quantum computers      (via sciencedaily.com)     Original source 

The potential of quantum computers is currently thwarted by a trade-off problem. Quantum systems that can carry out complex operations are less tolerant to errors and noise, while systems that are more protected against noise are harder and slower to compute with. Now a research team has created a unique system that combats the dilemma, thus paving the way for longer computation time and more robust quantum computers.

Simplicity versus adaptability: Understanding the balance between habitual and goal-directed behaviors      (via sciencedaily.com)     Original source 

Scientists have proposed a new AI method in which systems of habitual and goal-directed behaviors learn to help each other. Through computer simulations that mimicked the exploration of a maze, the method quickly adapts to changing environments and also reproduced the behavior of humans and animals after they had been accustomed to a certain environment for a long time. The study not only paves the way for the development of systems that adapt quickly and reliably in the burgeoning field of AI, but also provides clues to how we make decisions in the fields of neuroscience and psychology.
