First case of highly pathogenic avian influenza transmitted from cow to human confirmed      (via sciencedaily.com)     Original source 

in March a farm worker who reported no contact with sick or dead birds, but who was in contact with dairy cattle, began showing symptoms in the eye and samples were collected by the regional health department to test for potential influenza A. Experts have now confirmed the first case of highly pathogenic avian influenza transmission from a mammal (dairy cow) to a human.

Cats purrfectly demonstrate what it takes to trust robots      (via sciencedaily.com)     Original source 

Would you trust a robot to look after your cat? New research suggests it takes more than a carefully designed robot to care for your cat, the environment in which they operate is also vital, as well as human interaction.

World's largest hummingbird is actually two species      (via sciencedaily.com)     Original source 

The Giant Hummingbird of western South America is not one species but two, according to an international group of researchers. The northern population stays in the high Andes year-round while the southern population migrates from sea level up to 14,000 feet for the nonbreeding months.

Fruit fly testes offer potential tool against harmful insects      (via sciencedaily.com)     Original source 

A way to curb nagging insects has been flying under our radar -- an enzyme from fruit fly testes. The compound could control bugs that carry disease and harm crops by stunting their ability to procreate, researchers have found.

New viruses that could cause epidemics on the horizon      (via sciencedaily.com)     Original source 

Suddenly they appear and -- like the SARS-CoV-2 coronavirus -- can trigger major epidemics: Viruses that nobody had on their radar. They are not really new, but they have changed genetically. In particular, the exchange of genetic material between different virus species can lead to the sudden emergence of threatening pathogens with significantly altered characteristics.

Island birds more adaptable than previously thought      (via sciencedaily.com)     Original source 

The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.

Some varieties of annual flowers have a place in pollinator-friendly gardens      (via sciencedaily.com)     Original source 

While wildflowers and perennials are a must for supporting pollinators, there's no denying the popularity of many annual flowers for their colorful, visual appeal. A new study suggests choosing the right varieties can give annual flowers a role in nourishing bees and other pollinating insects in home gardens. Researchers observed pollinators visiting the six most popular annual flower species in the U.S., finding significant variation in pollinator attractiveness between cultivars, even within the same flower species.

A better way to control shape-shifting soft robots      (via sciencedaily.com)     Original source 

A new machine-learning technique can train and control a reconfigurable soft robot that can dynamically change its shape to complete a task. The researchers also built a simulator that can evaluate control algorithms for shape-shifting soft robots.

Generative AI that imitates human motion      (via sciencedaily.com)     Original source 

Walking and running is notoriously difficult to recreate in robots. Now, a group of researchers has overcome some of these challenges by creating an innovative method that employs central pattern generators -- neural circuits located in the spinal cord that generate rhythmic patterns of muscle activity -- with deep reinforcement learning. The method not only imitates walking and running motions but also generates movements for frequencies where motion data is absent, enables smooth transition movements from walking to running, and allows for adapting to environments with unstable surfaces.

New record holder for smallest dispersers of ingested seeds: Woodlice      (via sciencedaily.com)     Original source 

Even bugs as small as woodlice can disperse seeds they eat, setting a new record for smallest animal recorded to do so. The discovery underscores the crucial yet often overlooked role that small invertebrates play in ecosystems.

Acceptance of animals in urban environments      (via sciencedaily.com)     Original source 

How do city residents feel about animals in their immediate surroundings? A recent study shows how different the acceptance of various wild animals in urban areas is. Important factors are the places where the animals are found and their level of popularity -- squirrels and ladybugs come out on top here. The results have important implications for urban planning and nature conservation.

Swarms of miniature robots clean up microplastics and microbes, simultaneously      (via sciencedaily.com)     Original source 

When old food packaging, discarded children's toys and other mismanaged plastic waste break down into microplastics, they become even harder to clean up from oceans and waterways. These tiny bits of plastic also attract bacteria, including those that cause disease. Researchers describe swarms of microscale robots (microrobots) that captured bits of plastic and bacteria from water. Afterward, the bots were decontaminated and reused.

Bee body mass, pathogens and local climate influence heat tolerance      (via sciencedaily.com)     Original source 

How well bees tolerate temperature extremes could determine their ability to persist in a changing climate. But heat tolerance varies between and within populations, so entomologists examined bee physical traits to understand how these traits interact with environmental conditions, pathogens and other factors.
