A recent study from the University of Rochester found that humans rely on several brain regions to process sentences, not a single advanced area. The researchers used American Sign Language to investigate how different grammatical structures activate distinct brain regions.
Researchers at UC Berkeley found that dominant hyenas produce steady, confident-sounding giggles, while subordinate ones have more variable calls. The study's findings suggest that the frequency analysis of these calls can reveal an animal's social stature and age.
A U.S. Geological Survey scientist is using a satellite collar on a North Pole wolf named Brutus to learn about the Arctic wolves' behavior in winter. The collar collects and stores locations every day, which are then emailed to researchers, allowing them to track the wolf's movements and habitat use.
Researchers discovered that tropical paper wasps' brain structures alter to tackle complex tasks, integrating sensory inputs. The brain's dendrite network grows in complexity as the wasps transition from nest work to foraging, adapting to new environments.
A study in Evolution Canyon, Israel, shows that scorpion species exhibit different distributions on the south-facing and north-facing slopes, despite identical regional geology. The results suggest that environmental pressures, such as sunlight and drought, can lead to local changes in biodiversity.
A database detailing life history traits of over 4,000 animal species has been developed for studying ageing, evolution, and conservation. The AnAge resource provides insights into the mechanisms of ageing and how environmental adaptations influence lifespan, with potential applications in conservation efforts.
A recent study by Rensselaer Polytechnic Institute suggests that non-conscious exposure to advertisements can increase consumer preference for promoted products. The research, led by cognitive scientist Mark Changizi, reveals how advertising tactics like apparel branding and product placement in movies and TV shows tap into our brain's...
Researchers have generated a synthetic SARS-like bat coronavirus that is infectious in cultured cells and mice, identifying pathways by which a bat coronavirus may have adapted to infect humans. The findings provide a model approach for rapid identification, analysis, and public health responses to future natural or intentional virus e...
A new genus and species of primate, Diablomomys dalquesti, has been discovered in Texas dating back to 44-43 million years ago. The finding provides evidence that primates lingered in Texas longer than previously thought due to the warm climate during the late middle Eocene.
A new species of bacteria, Leptospira licerasiae, has been identified as a cause of severe leptospirosis in the Peruvian Amazon region. The pathogen was found to have novel biological features and is significantly different from other forms of the bacteria.
A Hebrew U study has shown that humans can detect finer frequency differences than animals, using single neuron recordings in the auditory cortex. This suggests a unique neural representation of frequency in the human brain.
Researchers argue that autistic savants' exceptional skills come at a cost in other aspects of processing, while animals process sensory inputs according to rules. This shared processing method is thought to be a specialized feature of the left hemisphere, common to both humans and nonhuman animals.
A Harvard University scientist has synthesized four key differences in human and animal cognition into a hypothesis on what exactly differentiates human and animal thought. The theory of
Researchers at Duke University Medical Center found that monkeys can perform mental arithmetic, solving problems with accuracy and speed similar to those of college students. The study suggests that basic arithmetic may be part of our shared evolutionary past.
Rats who received help in the past were more likely to help another unknown partner, demonstrating generalized reciprocal cooperation. This finding suggests that evolutionary explanations for cooperation in animals may be broader than previously thought, potentially involving cultural and anonymous experiences.
Researchers at Stanford University School of Medicine have identified two proteins, ROP16 and ROP18, that are critical to Toxoplasma's ability to infect and reproduce inside human cells. The study found that changes in these proteins can ramp up damage to the host by 10,000-fold.
A study found female budgerigars pair with males that sound like them, receiving more assistance during nesting. Males that mimic similar calls are also less aggressive and provide better support to females.
Researchers at New Mexico State University offer a new approach to understanding desertification by studying past events, environmental factors, and soil properties. Their six-step scheme integrates information from broad scale to fine scale to determine the most important influences.
The analysis shows that animals have varying sleep patterns to optimize their chances of finding food and avoiding danger. Human sleep follows similar rules as other animals, but is shorter in duration.
A positive relationship between male status and offspring count was found in a modern society subsample, indicating evolutionary forces may still be at work. This finding has implications for economics and management, explaining the striving for high and prestigious positions in men.
A new study found that horses with exercise-induced pulmonary hemorrhage (EIPH) trail the winner by an average of 14 feet after intense exercise. Horses with mild EIPH perform just as well as those without the disorder, but severe cases significantly hinder performance.
A new study reviews 80 published studies, finding that routine animal handling, blood collection, and force-feeding can cause significant stress responses. This stress can lead to impaired immune function and elevated levels of stress hormones.
Researchers found thousands of 600 million year old embryo microfossils in China's Doushantuo Formation. The discoveries suggest that these ancient embryos may have hatched into adult forms with tubular structures, linking them to a coral-like animal.
Researchers discovered that bacteria have acquired a gene from animal immune systems, allowing them to evade host defenses. This finding has significant implications for vaccine development and our understanding of bacterial evolution.
Researchers suggest that vibrant egg colours advertise females' ability to defend against deleterious free radicals, indicating genetic quality. This hypothesis can be applied to all animals with colourful eggs and paternal care.
Dr. David Bartel and colleagues have identified 16 novel miRNAs in Arabidopsis that regulate gene expression during development. The researchers demonstrate a plant homologue of the Dicer enzyme, CARPEL FACTORY (CAF), which processes plant miRNAs with sequence and structural similarities to animal miRNAs.
Scientists discovered a receptor tyrosine kinase in single-celled choanoflagellates, a group of protists with characteristics similar to those of multicellular animals. The finding provides strong support for the hypothesis that choanoflagellates are closely related to metazoans and may represent modern examples of animal ancestors.
Researchers propose that early animal life evolved to thrive in unique Cambrian environments with microbial mats. This new perspective suggests alternative evolutionary explanations for the development of strange morphologies, such as those seen in helicoplacoids, the earliest known echinoderms.
Arctic ground squirrels experience long periods of torpor punctuated by costly rewarming periods. Hibernation is about finding rest, not conserving energy, according to zoophysiologist Brian Barnes.
