See less to move better: Dynamic schooling of fish by visual selection and focus      (via sciencedaily.com)     Original source 

Sometimes less is more. Researchers accurately modeled dynamic fish schooling by incorporating the tendency of fish to focus on a single visual target instead of the whole school, as well as other visual cues.

Morals are key to consumer views on lab-grown meat, study finds      (via sciencedaily.com)     Original source 

People's moral values could limit their uptake of lab-grown meat, a study suggests. People who say living a natural life is morally important to them are more likely to reject lab-grown meat -- also known as cultured or cultivated meat -- than those who do not, research shows.

The courtship of leopard seals off the coast of South America      (via sciencedaily.com)     Original source 

A pioneering study has unveiled the first paired observations of sexual behavior and vocalizations in wild leopard seals. The study on the mysterious leopard seal represents a major advance in understanding the behavior of one of the most difficult apex predators to study on Earth.

The most endangered fish are the least studied      (via sciencedaily.com)     Original source 

The most threatened reef fishes are also the most overlooked by scientists and the general public. Scientists measured the level of human interest in 2,408 species of marine reef fish and found that the attention of the scientific community is attracted by the commercial value more than the ecological value of the fishes. The public, on the other hand, is primarily influenced by the aesthetic characteristics of certain species, such as the red lionfish (Pterois volitans) and the mandarinfish (Synchiropus splendidus).

Logged forests can still have ecological value -- if not pushed too far      (via sciencedaily.com)     Original source 

Researchers have analysed data from 127 studies to reveal 'thresholds' for when logged rainforests lose the ability to sustain themselves. The results could widen the scope of which forests are considered 'worth' conserving, but also show how much logging degrades forests beyond the point of no return.

Influenza viruses can use two ways to infect cells      (via sciencedaily.com)     Original source 

Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers have now discovered that certain human flu viruses and avian flu viruses can also use a second entry pathway, a protein complex of the immune system, to infect cells. This ability helps the viruses infect different species -- and potentially jump between animals and humans.

Could intensive farming raise risk of new pandemics?      (via sciencedaily.com)     Original source 

Industrialized farming is often thought to reduce the risk of zoonotic diseases because of better control, biosecurity and separation of livestock. A new study examines the effect of social and economic factors -- which are often overlooked in traditional assessments.

Researchers find that frogs can quickly increase their tolerance to pesticides      (via sciencedaily.com)     Original source 

Although there is a large body of research on pests evolving tolerances for the pesticides meant to destroy them, there have been considerably fewer studies on how non-target animals in these ecosystems may do the same.

Receptors make dairy cows a prime target for influenza      (via sciencedaily.com)     Original source 

A study helps explain why dairy cows infected by highly pathogenic avian influenza are shedding the virus in their milk. Their findings could help develop biosecurity measures aimed at slowing the spread of the illness.

A stealth fungus has decimated North American bats but scientists may be a step closer to treating white-nose syndrome      (via sciencedaily.com)     Original source 

An invasive fungus that colonizes the skin of hibernating bats with deadly consequences is a stealthy invader that uses multiple strategies to slip into the small mammals' skin cells and quietly manipulate them to aid its own survival. The fungus, which causes the disease white-nose syndrome, has devastated several North American species over the last 18 years.

Hatcheries can boost wild salmon numbers but reduce diversity, studies find      (via sciencedaily.com)     Original source 

The ability of salmon hatcheries to increase wild salmon abundance may come at the cost of reduced diversity among wild salmon, according to a new study.

Introducing co-cultures: When co-habiting animal species share culture      (via sciencedaily.com)     Original source 

Cooperative hunting, resource sharing, and using the same signals to communicate the same information -- these are all examples of cultural sharing that have been observed between distinct animal species. In a new article, researchers introduce the term 'co-culture' to describe cultural sharing between animal species. These relationships are mutual and go beyond one species watching and mimicking another species' behavior -- in co-cultures, both species influence each other in substantial ways.

Blood fat profiles confirm health benefits of replacing butter with high-quality plant oils      (via sciencedaily.com)     Original source 

Switching from a diet high in saturated animal fats to one rich in plant-based unsaturated fats affects the fat composition in the blood, which in turn influences long-term disease risk. A study shows that it is possible to accurately measure diet-related fat changes in the blood and directly link them to the risk of developing cardiovascular disease and type 2 diabetes.

Air pollution harms pollinators more than pests, study finds      (via sciencedaily.com)     Original source 

Pollinators experienced a 39-percent decline in foraging efficiency after being exposed to elevated air pollution levels. In contrast, plant-eating aphids and other pests were not significantly impacted.
