Individual differences in the brain

Scientists selectively bred zebrafish to exhibit distinct personality traits, finding that brain activities soon changed and new brain regions were activated. The study suggests a rapid pace of personality trait changes and potential implications for human behavior.

Humans and flies employ very similar mechanisms for brain development and function

Research has found that the brains of humans, flies, and mice share similar mechanisms for brain development and function. This similarity can be interpreted in two ways: as evidence of a single ancestral brain or independent evolution of brain circuits. The study identified shared genetic regulatory mechanisms controlling brain area f...

'Little brain' or cerebellum not so little after all

New research using ultra-high-field MRI reveals the cerebellum has a surface area equal to 80% of the cerebral cortex's surface area, challenging the long-held idea that it is smaller. This expansion is linked to human behavior and cognition evolution, enabling the processing of complex concepts like language and abstract reasoning.

'Selfish and loveless' society in Uganda really is not

A Baylor University study led by Cathryn Townsend challenges the long-held notion that the Ik ethnic group in Uganda is selfish and loveless. The research found that sharing and cooperation are integral to Ik culture, with a strong emphasis on supernatural punishment for those who do not share.

Dolphins learn in similar ways to great apes

Dolphins use complex techniques like 'shelling' to obtain food, a behavior comparable to tool use in humans. A study revealed that dolphins learn new foraging methods mainly through social transmission among peers, similar to great apes and gorillas. This discovery expands our understanding of how dolphins adapt to changing environment...

An ant-inspired approach to mathematical sampling

A team of researchers from the University of Bristol developed an ant-inspired method for mathematical sampling, which outperforms traditional methods. The study found that ants' collective behavior can be used to create a more efficient way of exploring complex probability distributions.

Decide now or wait for something better?

Researchers developed a mathematical model to describe human behavior in various scenarios, helping to understand decision-making. The study found that people tend to use a linear threshold model, increasing the price they're willing to pay over time.

People more likely to accept nudges if they know how they work and how effective they are

A recent study from Queen Mary University of London and the University of Oxford found that people are more likely to accept nudges if they know how they work and how effective they are. The study involved over 1700 participants from the US and UK, who were presented with examples of genuine behavioral interventions used by policymakers.

Yes, your dog wants to rescue you

A recent study by Arizona State University's Canine Science Collaboratory found that pet dogs will attempt to rescue their owners if they know how. Approximately one-third of the dogs in the experiment rescued their owners, suggesting that motivation alone is not enough, but rather a combination of understanding and ability are required.

A lost world and extinct ecosystem

Researchers at Arizona State University have discovered the earliest evidence for symbolic behavior, complex pyrotechnology, and projectile weapons in South African archaeological sites. The study reveals that a vast plain, now submerged undersea, was a key foraging habitat for early modern humans during glacial phases.

Biorobotics is the future of fish farming

A study published in Royal Society Open Science found that small and slowly moving robots can effectively monitor the behavior of salmon in fish farms without scaring them off. The results suggest that these robots can provide valuable insights into the state of the fish, including their health, parasites, and feeding habits.

New UTA study finds people tune out facts and trust their guts in medical emergencies

A new study by University of Texas at Arlington researchers found that people tend to rely on personal anecdotes rather than facts during medical emergencies, such as the COVID-19 pandemic. This bias can lead to irrational decision-making and a lack of fact-based decision-making when individuals feel vulnerable.

Evolution of sedentary behaviors

Researchers examined Hadza adults' activity patterns, finding they spent nearly 10 hours a day in nonambulatory postures similar to industrialized populations. However, Hadza adults spent more time in squatting and kneeling postures, which produce muscle activity, suggesting humans need daily muscle activity from both movement and resting
