Blue and great tits deploy surprisingly powerful memories to find food      (via sciencedaily.com)     Original source 

Blue and great tits recall what they have eaten in the past, where they found the food and when they found it, a new study shows. In the first experiment of its kind to involve wild animals, blue and great tits demonstrated 'episodic-like' memory to cope with changes in food availability when foraging. The same study may suggest that humans leaving out seeds and nuts for garden birds could be contributing to the evolution of these memory traits.

Spotted apex predator being pressured by spotted pack hunters -- and it's our fault      (via sciencedaily.com)     Original source 

Leopards, who are already in decline, can't keep up with hyenas when people are around. As we humans move into the their territories more and more, we are helping to disturb and unbalance ecosystems. This has been shown in a new study where researchers used camera traps to observe both large carnivore species.

Genetic patterns of world's farmed, domesticated foxes revealed via historical deep-dive      (via sciencedaily.com)     Original source 

Domesticated animals play a prominent role in our society, with two-thirds of American families enjoying the companionship of pets and many others relying on animal products for their nutritional needs. But the process of domestication remains a bit of a mystery.

New and improved camera inspired by the human eye      (via sciencedaily.com)     Original source 

Computer scientists have invented a camera mechanism that improves how robots see and react to the world around them. Inspired by how the human eye works, their innovative camera system mimics the tiny involuntary movements used by the eye to maintain clear and stable vision over time.

The evidence is mounting: humans were responsible for the extinction of large mammals      (via sciencedaily.com)     Original source 

Human hunting, not climate change, played a decisive role in the extinction of large mammals over the last 50,000 years. This conclusion comes from researchers who reviewed over 300 scientific articles from many different fields of research.

Researchers develop fastest possible flow algorithm      (via sciencedaily.com)     Original source 

Computer scientists have written a network flow algorithm that computes almost as fast as is mathematically possible. This algorithm computes the maximum traffic flow with minimum transport costs for any type of network. It thus solves a key question in theoretical computer science. The superfast algorithm also lays the foundation for efficiently computing very large and dynamically changing networks in the future.

New mathematical model sheds light on the absence of breastfeeding in male mammals      (via sciencedaily.com)     Original source 

Mathematicians ave put forward a hypothesis which suggests that the reason male mammals don't breastfeed might be driven by the rich community of microbes that lives in breast milk and which plays an important part in establishing the gut microbiome of the infant.

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.
