Acute sense of touch helps hummingbirds hover near a flower without bumping into it      (via sciencedaily.com)     Original source 

Hummingbird flight mechanics have been well studied but far less is known about how their sense of touch helps them sip nectar from a flower without bumping into it. Most of what scientists know about how touch is processed in the brain comes from studies on mammals, but bird brains are very different from mammal brains. New research shows that touch and air pressure on the wings and legs activate specific clusters of neurons in two regions of the forebrain to create a map of their body, which may help hummingbirds make nuanced adjustments to flight.

Fatal attraction: When endangered species try to mate with domestic relatives, both wildlife and people lose      (via sciencedaily.com)     Original source 

Sticks and stones aren't enough to thwart biological attraction, but sometimes those are the only tools available to pastoralists trying to prevent wildlife from eloping with their livestock. A new study brings awareness to both the human impacts of these encounters -- ranging from economic loss to death -- and conservation concerns for the wild animals that are often endangered.

Wild megalopolis: Study shows unexpected pockets of biodiversity pepper Los Angeles      (via sciencedaily.com)     Original source 

Researchers, in partnership with the city of Los Angeles, have developed the urban association index to help identify how well or poorly individual wildlife species are doing in the city. The researchers found unexpected pockets of biodiversity deep in the city, but they say it will still be a challenge to elevate Los Angeles' overall level of biodiversity.

The secret sex life of coral revealed      (via sciencedaily.com)     Original source 

Corals play an essential role in ocean ecosystems, and like many organisms, they are under threat from climate change and other human activities. To better protect coral, it's first necessary to understand them, in particular their reproductive life cycle, which only happens once a year. For the first time, researchers have produced a model for coral spawning, based on various environmental factors. They achieved this by tapping an often overlooked source of aquatic knowledge, an aquarium.

Smarter foragers do not forage smarter      (via sciencedaily.com)     Original source 

Why do primates have big brains? In the Panamanian rainforest, scientists pitted large-brained primates against smaller-brained mammals to find out who was the smartest forager.

Why do Dyeing poison frogs tap dance?      (via sciencedaily.com)     Original source 

The toe tapping behavior of various amphibians has long attracted attention from researchers and pet owners. Despite being widely documented, the underlying functional role is poorly understood. In a new paper, researchers demonstrate that Dyeing poison frogs modulate their taps based on specific stimuli.

Tracking animals without markers in the wild      (via sciencedaily.com)     Original source 

Researchers developed a computer vision framework for posture estimation and identity tracking which they can use in indoor environments as well as in the wild. They have thus taken an important step towards markerless tracking of animals in the wild using computer vision and machine learning.

How killifish embryos use suspended animation to survive over 8 months of drought      (via sciencedaily.com)     Original source 

The African turquoise killifish lives in ephemeral ponds in Zimbabwe and Mozambique. To survive the annual dry season, the fish's embryos enter a state of extreme suspended animation or 'diapause' for approximately 8 months. Now, researchers have uncovered the mechanisms that enabled the killifish to evolve this extreme survival state.

Echidnapus identified from an 'Age of Monotremes'      (via sciencedaily.com)     Original source 

Australian researchers have found evidence of the oldest known platypus and a new species, dubbed 'echidnapus', which has a platypus-like anatomy alongside features that more closely resemble an echidna.

Entomologist sheds light on 250-year-old mystery of the German cockroach      (via sciencedaily.com)     Original source 

Entomologists have solved the 250-year-old origin puzzle of the most prevalent indoor urban pest insect on the planet: the German cockroach. The team's research findings, representing the genomic analyses of over 280 specimens from 17 countries and six continents, show that this species evolved some 2,100 years ago from an outdoor-living species in Asia.

High H5N1 influenza levels found in mice given raw milk from infected dairy cows      (via sciencedaily.com)     Original source 

Mice administered raw milk samples from dairy cows infected with H5N1 influenza experienced high virus levels in their respiratory organs and lower virus levels in other vital organs, according to new findings. The results suggest that consumption of raw milk by animals poses a risk for H5N1 infection and raises questions about its potential risk in humans.

Key role of plant-bacteria communication for the assembly of a healthy plant microbiome supporting sustainable plant nutrition      (via sciencedaily.com)     Original source 

In an interdisciplinary study, researchers discovered that symbiotic bacteria communicate with legume plants through specific molecules and that this communication influences which bacteria grow near the plant roots. The findings provide insights into how plants and soil bacteria form beneficial partnerships for nutrient uptake and resilience. These results are a step towards understanding how communication between plants and soil bacteria can lead to specific beneficial associations providing plants with nutrients.

Psychedelic drug-induced hyperconnectivity in the brain helps clarify altered subjective experiences      (via sciencedaily.com)     Original source 

A new study shows that the use of psilocybin, a compound found in the widely known 'magic mushrooms,' initiates a pattern of hyperconnectivity in the brain linked to the ego-modifying effects and feelings of oceanic boundlessness. The findings help explain the so-called mystical experiences people report during the use of psychedelics and are pertinent to the psychotherapeutic applications of psychedelic drugs to treat psychiatric disorders such as depression.

Designing a better nest to help endangered turtles      (via sciencedaily.com)     Original source 

With Ontario's eight species of turtles considered at risk, a new nest designed by researchers has the potential to significantly bolster their struggling populations. The habitat is the first designed for turtles in rock barren landscapes, such as the research site around Georgian Bay. It uses moss and lichen. The researchers found that the design provided a more stable environment for incubating eggs compared to natural sites, where the probability of an egg hatching was only 10 per cent compared to 41 per cent in the created site.

Bigger is better: Male proboscis monkeys' enhanced noses evolved to attract mates      (via sciencedaily.com)     Original source 

When it comes to the animal kingdom, bigger is better. Well, at least for proboscis monkeys, famously known for their long, large and droopy noses. Researchers have provided a world-first explanation for why male proboscis monkeys have larger and 'enhanced' nasal structures.
