A study analyzed fossil dermal denticles from ancient coral reefs and modern reefs to estimate Caribbean shark abundance before and after human settlement. The results show a significant decline in shark populations, with fast-swimming species facing the greatest losses.
Researchers found that Siberian jays exclusively trust warning calls from members of their own group, ignoring those from neighboring territories. This social knowledge mechanism may have played a role in the diversification of human languages and dialects.
Researchers used live human cortical tissue to identify functionally important features that make human neurons unique, revealing a massive amount of diversity among human neocortical pyramidal cells. The team found distinct electrophysiological features between neurons located at different layers in the human neocortex.
A new study by the University of Sydney suggests that climate change and environmental pressure are key factors in predicting the emergence of pandemics. The researchers found a link between higher human population density, forest coverage, and disease diversity, particularly in countries with larger land areas and more dense populations.
A team of researchers found that diverse biologically and culturally rich regions exhibit even greater diversity than expected. The study, published in Scientific Reports, suggests a link between complexity and diversity across different domains.
Research reveals differing preferences for suffixes and prefixes across languages, including African Bantu language Kîîtharaka. English speakers favor suffixes, while Kîîtharaka speakers prefer prefixes.
Researchers at UC Santa Cruz developed an efficient de novo human genome assembly algorithm using the Shasta toolkit, achieving high accuracy and scalability. The algorithm can assemble a complete human genome in under six hours and costs around $70, paving the way for pangenome research to represent true human diversity.
A comprehensive analysis of 929 human genomes provides unprecedented detail of our genetic history, highlighting the complexity of human evolution and its impact on disease susceptibility. The study identifies millions of previously unknown DNA variations that may influence susceptibility to different diseases.
Rick Guidotti, founder of POSITIVE EXPOSURE, receives ASHG Advocacy Award for his innovative use of visual arts to celebrate human diversity. He has promoted genetics awareness, funding for biomedical research, and integrating genetics into health systems.
Researchers found Snowball's movement diversity is not limited to humans, suggesting an innate ability to respond to music with intentional movements. The study proposes five traits that may explain the shared natural ability to dance in humans and parrots.
The Human Genetics Scholars Initiative aims to increase workforce diversity in human genetics research by providing intensive mentoring, skill-building, and community-building opportunities. The program will support up to 240 diverse young researchers over five years.
The bias in human genomics research limits understanding of health and disease, and the ability to make accurate predictions and develop new treatments. The authors call for increased diversity in studies to address health inequalities and mistrust
A recent study found that high levels of human impact on chimpanzee habitats lead to a significant reduction in behavioral diversity. The researchers analyzed data from 144 social groups across Africa and found that behaviors such as tool use, nut consumption, and thermoregulation were lost at sites with high human disturbance.
Researchers found that chimpanzee behavioral diversity is reduced by 88% in areas with high human impact, indicating a loss of cultural traditions and social learning opportunities. This study highlights the need to protect animal behavioral diversity as part of biodiversity conservation efforts.
Research on 144 chimpanzee groups found that high levels of human impact significantly reduce behavioral diversity, including the loss of unique tools and hunting behaviors. The study suggests population size and social learning play key roles in maintaining cultural traits.
Researchers identify major transitions in human cultural evolution using computational methods and large cross-cultural datasets. The study reveals the complex processes underlying our cultural histories, including changes from small kin-based groups to colossal nation states.
Researchers developed a new approach to model human immune variation, identifying gene markers that correlate with human disease outcomes. The study found that accounting for immune diversity is critical for predicting disease outcomes.
A team of international researchers used a form of simulation modeling to study the processes shaping language diversity patterns in Australia. They found strong evidence that rainfall and limits to group size shaped both the total number of languages and the geographic patterns of language diversity on the continent. This study provid...
New research reveals that human-provided food shortens bears' hibernation period by up to 56%, leading to increased interactions with other species and humans. This study has important management implications for bear conservation.
A recent study suggests that individuals with autism may have played an important role in their social groups due to their exceptional memory skills and heightened perception. Collaborative morality, which emerged around 100,000 years ago, allowed for the acceptance and respect of people with autistic traits.
A team of scientists, including Michael Yudell, Dorothy Roberts, and Sarah Tishkoff, recommend phasing out race from genetic research due to its lack of clear-cut genetic boundaries. Instead, they propose using terms like 'ancestry' or 'population' to describe grouping for studies.
A study published by SAGE in Human Relations found that diversity in the boardroom is key to advancing LGBT-inclusive policies. Firms with a higher percentage of women on the board are more likely to adopt a broad range of LGBT-friendly policies and practices.
New research has found significant differences in the body structure of early human ancestors, including facial features and skeletal traits. The discovery of a 1.9 million-year-old pelvis and femur fossil reveals greater diversity in the human family tree than previously thought.
Researchers tracked bacterial colonies using experimental tools to observe massive phenotypic diversification in aging Escherichia coli colonies. They found diverse metabolic capacities, stress resistance, and improved biofilm production among survivors of senescent colonies.
Research from the University of British Columbia found that Canadian print news articles frequently use words that legitimize sexual exploitation and portray victims as 'business' or 'trade'. The study suggests improvements are needed for accurate reporting to avoid perpetuating stereotypes.
A study reveals cultural variations in spatial relationships, with nomadic hunter-gatherers remembering body movements differently than Westerners. German children followed a consistent pattern, while Hai||om children adapted their movements based on direction.
A team of linguists, led by Professor Michael Krauss, will document 11 endangered languages in Alaska using a $1.2 million grant from the National Science Foundation. The project aims to preserve the Atuuan dialect, Southern Tsimshian, and other critically endangered languages.
Researchers examined over 7,000 plant species in the human diet, finding that humans consume a remarkably high number of plant families. A study of a McDonald's Big Mac meal revealed approximately 20 different species and ingredients originating from around the world.
Companies recognized for diversity may prioritize surface-level recruiting over comprehensive programs, while those in top human resources departments focus on work environment improvements. Researchers found that diversity initiatives are more effective when driven by business goals, such as boosting productivity and profitability.
A new study reveals that pathogens play a significant role in shaping the evolution of human's most diverse genes, specifically those encoding Human Leukocyte Antigen (HLA) proteins. High HLA diversity is found to correlate with high pathogen diversity, particularly for certain types of HLA genes.
An ivory statuette of a lion-tamer may be part of the throne given to Apollo by King Midas, according to Dr. Keith DeVries. The statuette's style and date match Phrygian art from Turkey, supporting a strong case for its association with the king's throne.
The Human Genome project has a limited representation of global genetic diversity due to an inadequate sample size from sub-Saharan Africa. This exclusion ignores the worldwide genetic variation and evolutionary history of the human species, according to anthropologist Todd R Disotell.
