Scientists at Cold Spring Harbor Laboratory are studying Alston's singing mice to better comprehend the evolutionary origins of vocal communication. The research may also hold clues for understanding strokes, autism, and other speech-related disorders. The study found that singing mice use a common brain region for both singing and ult...
Researchers discovered that hatchling loggerhead turtles feel the Earth’s magnetic map to determine their location on epic migration routes. By zapping them with a strong magnetic pulse, scientists confirmed that these turtles use magnetism to navigate and determine direction.
A recent study by Nagoya University researchers has revealed that zebrafish have enlarged areas in their spinal cords, corresponding to the paired pectoral and pelvic fins. The findings suggest an evolutionary theory: when tetrapods evolved from fish, only the paired fins transformed into limbs, while unpaired fins disappeared.
Researchers discovered seals can detect size differences of just 17.6mm between vortex rings, helping them identify fish escape directions. This ability may allow seals to outmaneuver fleeing fish.
The study found that a specific spinal circuit is involved in both ejaculation and arousal, and integrates sensory inputs to adjust its output based on the animal's internal state. The researchers also discovered that Gal⁺ neurons receive sensory input from the penis and can trigger ejaculation, but their effects are suppressed by brai...
New research suggests that rapid brain growth in marmoset infants, similar to human babies, enables them to learn language through feedback from caregivers. This learning strategy makes humans an oddity within the animal kingdom.
Researchers found that harbour seals can determine their heading from optic flow fields, even in cloudy or opaque water. The team created a gaming challenge for the seals, using particle simulations to show them which direction they were moving in, and found that they consistently chose the correct direction.
A study by scientists at the Smithsonian Tropical Research Institute found that juvenile fringe-lipped bats do not initially differentiate between palatable and unpalatable frogs and toads, but learn to identify toxic species through experience. As they mature, adult bats respond more strongly to palatable prey.
Eye saccades enable mammals to chase prey and navigate through complex environments by aligning with optic flow, reducing motion blur. This mechanism allows animals to track erratic movements and react flexibly to changes in direction.
Researchers discovered that fruit fly Drosophila busckii can detect and thrive on toxic food sources, including dimethyldisulfide, an unpleasantly smelling sulfur compound. The fly's unique adaptations provide a valuable model for studying toxin tolerance and ecological concepts.
Researchers found that desert ants rely on the polarity of the geomagnetic field to navigate during learning walks, contradicting previous findings in other insects. The team manipulated magnetic fields and observed the ants' behavior, concluding that a compass-like navigation system is useful for short-distance navigation.
A team of scientists has pinpointed a critical neural circuit for female sexual rejection, revealing how the brain integrates signals to shape behavior. The ventromedial hypothalamus, specifically progesterone-sensitive neurons in the anterior VMH, play a crucial role in determining whether a female accepts or rejects mating attempts.
A study by Eötvös Loránd University found that domestication and human socialization alone are insufficient to trigger a human-analog attachment bond in companion animals. Dogs displayed specific behaviors typical of the attachment bond, unlike pigs, which did not exhibit these behaviors.
Researchers found that dogs matched their emotional state with the content of human vocalizations, while pigs exhibited stress behaviors to unusual humming sounds. This suggests that domestication may have facilitated emotional contagion in dogs.
The study reveals a unique, ring-shaped organization of the antennal lobe, with specific glomerular clusters encoding different odors. This coding mechanism differs from other insects and vertebrates, with the representation of odor valence encoded in higher brain centers.
Researchers found that elevated ozone levels remove mating barriers between different fly species, leading to increased hybridization and sterile offspring. The study used four species of Drosophila and found that ozone concentrations often measured on hot days can cause flies to mate with closely related species.
Researchers have solved the long-standing question of what triggers the alarm response in fish by identifying two distinct chemical signals: Daniol sulphate and Ostariopterin. These substances convey separate pieces of information that must be detected simultaneously to trigger a flight-or-freeze response.
Research found that female silkmoth long sensilla recognize silkworm feces as a deterrent, helping females avoid mulberry trees with high silkworm populations. In contrast, male silkmoths have specialized antennae to detect female sex pheromones, but no clear male counterpart has been identified.
Researchers examine the dynamic nature of fear responses in varied environments, shedding light on physical manifestation of memory in the brain. The study reveals that fear memories are linked to pathological states like PTSD and generalized anxiety, with direct translational relevance for disorders involving dysregulated fear responses.
Researchers discovered that octopuses transition between quiet and active stages of sleep, with the latter resembling neural activity seen when awake. This active stage may be essential for octopus function and potentially related to dreaming.
Scientists at UC Santa Barbara discovered a unique pathway in fruit flies that reduces the sensation of pain from heat, with a single pair of neurons called 'Epi' neurons playing a crucial role. The Epi neurons produce a neuropeptide that suppresses thermal nociception, contradicting their role in fly larvae.
Researchers at Sainsbury Wellcome Centre found that instinctual exploratory runs enable mice to learn a map of the world efficiently. The study demonstrates how biological brains can learn faster and more efficiently than AI agents by focusing on salient objects.
Ozone exposure destroys pheromones essential for fly mating, leading to abnormal behavior and reduced female attraction. The study's findings highlight the devastating impact of air pollution on insect populations.
Researchers found that companion dogs, but not pigs, would show their owners the location of a food reward out-of-reach. This suggests that directing humans' attention to interesting locations may not be a universal ability among domestic animals. Dogs and other visually communicative species were more likely to use this behavior.
Neuroscientists demonstrate that mice can learn to suppress their innate escape response, effectively ignoring stimuli deemed non-threatening. The study's findings show that this suppression is specific to the stimulus and dependent on recent threat-escape history.
Researchers discovered that robber flies employ a combination of two strategies to navigate cluttered environments and capture prey. They use an obstacle avoidance strategy to swerve around obstructions, which is then followed by a resumption of the conventional interception path once the fly has passed the obstacle.
A new study published in Nature Communications found that amylin peptide plays a crucial role in regulating social contact-seeking behavior in female mice. The researchers discovered that isolation leads to a decrease in amylin levels, while social reunion increases them.
Researchers discovered that female tobacco hawkmoths opt for plant sites with three-lined potato beetles over uninfested ones, potentially benefiting from the beetle's scent. This unique behavior is a cost-benefit trade-off where avoiding parasitic wasps outweighs the disadvantage of food competition.
A new study by researchers from Eötvös Loránd University found that dog brains can differentiate between two languages, with distinct activity patterns in primary and secondary auditory cortices. The study used brain imaging to compare dogs' responses to speech and non-speech stimuli in Spanish and Hungarian.
A new study by Hungarian researchers finds that dogs use complex computations and brain regions similar to humans to learn word boundaries in speech. Dogs can recognize syllable patterning, such as frequent words with consistent syllables, and use this information to extract words from continuous speech.
Researchers at Eötvös Loránd University discovered that dogs exhibit attachment behaviors similar to human infants, responding positively to their owner's speech. The study found that the reward center of a dog's brain is more sensitive to its owner's voice compared to a familiar person's praise.
