Do some electric fish sense the world through comrades' auras?      (via sciencedaily.com)     Original source 

It would be a game-changer if all members of a basketball team could see out of each other's eyes in addition to their own. Biologists have found evidence that this kind of collective sensing occurs in close-knit groups of African weakly electric fish, also known as elephantnose fish. This instantaneous sharing of sensory intelligence could help the fish locate food, friends and foes.

Lab-grown liver organoid to speed up turtle research, making useful traits easier to harness      (via sciencedaily.com)     Original source 

Researchers developed protocols for growing organoids that mimic a turtle liver, the first organoids developed for a turtle and only the second for any reptile. The discovery will aid deeper study of turtle genetics, including the cause of traits with potential medical applications for humans such as the ability to survive weeks without oxygen.

Conservation actions for SA's white shark population now a matter of urgency      (via sciencedaily.com)     Original source 

A group of marine biologists specializing in shark ecology, genetics and fisheries have challenged the findings from a recent study suggesting that South Africa's white shark population has not decreased, but simply redistributed eastwards to flee predation from orcas.

Fossil named 'Attenborough's strange bird' was the first in its kind without teeth      (via sciencedaily.com)     Original source 

A new fossil, named 'Attenborough's strange bird' after naturalist and documentarian Sir David Attenborough, is the first of its kind to evolve a toothless beak. It's from a branch of the bird family tree that went extinct in the mass extinction 66 million years ago, and this strange bird is another puzzle piece that helps explain why some birds -- and their fellow dinosaurs -- went extinct, and others survived to today.

New research shows migrating animals learn by experience      (via sciencedaily.com)     Original source 

Individual white storks incrementally straightened their migration routes to find more direct ways to move between destinations during the spring migration to summer breeding and nesting grounds, suggesting that experiential learning is an important part of successful migration.

The crow's best friend: Humans      (via sciencedaily.com)     Original source 

A new study has found that when humans are suddenly absent from the urban environment, the activity of the crows and ringneck parakeets that 'live' in the area reduces significantly. Conversely, the graceful prinias, who are generally considered shy, increased their activity.

A model for the evolution of intelligence      (via sciencedaily.com)     Original source 

When certain species of wild birds and primates discover new ways of finding food in the wild, it can serve to measure their flexibility and intelligence. In the largest experimental study ever conducted on this topic, researchers have shown that foraging problems requiring overcoming obstacles, such as removing the lid off a container of food, are the only predictors of brain size and innovative behavior in the wild.

In wake of powerful cyclone, remarkable recovery of Pacific island's forests      (via sciencedaily.com)     Original source 

After one of the most intense cyclones in world history tore through the Pacific island of Tanna in Vanuatu, new research showed the resilience of the island's forests.

Study results show 25% of pregnant people are not getting enough omega-3 fatty acids from their diet or dietary supplements      (via sciencedaily.com)     Original source 

Results from a new US nationwide cohort study show that, despite strong recommendations in favor of consuming omega-3 fatty acids for optimal pregnancy outcomes and offspring health, 25% of participants reported rarely, or never eating fish during pregnancy, with fewer taking omega-3 supplements.

Shining a light on the effects of habituation and neural adaptation on the evolution of animal signals      (via sciencedaily.com)     Original source 

A new paper examines the possible effects of two properties of receiver playing fields documented in studies of animal psychology -- habituation and neural adaptation -- on the efficacy of mate choice signals.

Researchers have discovered 18 new species of Enterococcus type bacteria from soil samples collected from all corners of the globe, which may offer new clues to the origins of antibiotic-resistant infections in hospitals.

Slimming down a colossal fossil whale      (via sciencedaily.com)     Original source 

A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.

Small dietary changes can cut your carbon footprint by 25%      (via sciencedaily.com)     Original source 

New research provides compelling evidence that partially substituting animal with plant protein foods can increase life expectancy and decrease greenhouse gas emissions. Importantly, it also suggests that benefits depend on the type of animal protein being replaced. The study drew data from a national nutrition survey to analyze Canadians' dietary records. The study modeled partial replacements (25% and 50%) of either red and processed meat or dairy with plant protein foods like nuts, seeds, legumes, tofu, and fortified soy beverages, on a combination of nutrition, health, and climate outcomes.

Uncertainty in measuring biodiversity change could hinder progress towards global targets for nature      (via sciencedaily.com)     Original source 

More than ever before, there is a growing interest in dedicating resources to stop the loss of biodiversity, as recently exemplified by the Kunming-Montreal Global Biodiversity Framework (GBF) decided at COP15 in December 2022. The GBF focuses on understanding why biodiversity is declining and what actions are needed to reverse this trend. However, according to researchers, implementing the plan is challenging because information about biodiversity changes is not evenly available everywhere, and is uncertain in many places.

The Golgi organelle's ribbon structure is not exclusive to vertebrates, contrary to previous consensus      (via sciencedaily.com)     Original source 

Researchers report that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins. The function of the Golgi ribbon is still enigmatic, but its presence in diverse animal lineages indicates that its function is not vertebrate specific, as previously thought. The team also showed Golgi ribbons form at a specific timepoint during embryogenesis, which suggests that they might play a role in cell differentiation.

Bottlenecks and beehives: How an invasive bee colony defied genetic expectations      (via sciencedaily.com)     Original source 

An invasive Asian honeybee colony in northern Australia has defied expectations, displaying emergent genetic variation in a short period of time. While bad news for biosecurity agencies, it could be a sign that species under pressure from climate change can be resilient.

The veil varies more than the threat: Predator selection on variability in camouflage and warning signals      (via sciencedaily.com)     Original source 

Researchers leveraged open-access digital collections to validate an age-old hypothesis in evolutionary ecology. The classic hypothesis proposes that predators select for a great variety of camouflage and a limited variety of warning signals, but the idea has never been tested on natural prey.
